What makes the 3.0 CSL unique?
The 3.0 CSL is a lightweight, performance-oriented version of the standard 3.0 CS/3.0 CSi coupe. It was originally developed as a homologation model for the German Touring Car Championship by a separate division within BMW AG, a division that would later become BMW Motorsport GmbH.
Is the 3.0CSL considered an M car?
Because the 3.0 CSL was conceived by BMW's competition department, which would be formally incorporated in 1972 as BMW Motorsport GmbH (later renamed BMW M GmbH), it is therefore generally considered to be the first M Series model. Though it does not carry an M badge, the 3.0 CSL would eventually be offered with the tri-color stripes that would form the icon of the M division.
What do the letters "CSL" designate?
The "CS" suffix denotes "Coupe Sport" and was introduced with the Bertone-designed 3200 CS of 1962. The "L" was added to this version of the 3.0 CS in order to denote "Lightweight"
How much lighter is the 3.0 CSL compared to the steel-bodied 3.0 CS?
According to official BMW figures, a non-optioned 3.0 CSL with all the aluminum body panels weighs 2,568 pounds or about 440 pounds less than an equivalent 3.0 CS. City Package-equipped models are 297 pounds heavier than the standard 3.0 CSL at 2,865 pounds.
Why is the later 3.0 CSL sometimes referred to as the "Batmobile"?
In addition to the standard front airdam and rear spoiler, 3.2-liter CSL models could be fitted with a removable "racing kit" consisting of an air guide mounted above the rear window and an enlarged rear spoiler, both designed to increase downforce on the competition machines. The addition of these rather striking appendages resulted in the nickname "Batmobile." Because these items were required on the road version for homologation purpose but could not be installed at the factory due to a conflict with various European laws, they were supplied as the removable kit.
Production Data
How many versions of the 3.0 CSL were developed?
BMW developed four different versions of the 3.0 CSL over five years, all to European specification. The original 1971 version utilized the standard 2,985-cc M30 engine with twin carburetors and was produced only in left-hand drive. A fuel-injected model displacing 3,003cc replaced the earlier carbureted version and was produced in both left-hand drive and right-hand drive forms during 1972 and 1973. The final iteration of the 3.0 CSL, all in left-hand drive and with a larger 3,153-cc engine, was built in two distinct production runs during 1973 (first batch) and 1974-75 (second batch).
How many of each version of the 3.0 CSL were produced?
3.0 Carburettor (LHD): 169 built from 9/71 thru 7/72
3.0 Injection (LHD): 429 built from 9/72 thru 6/73
3.0 Injection (RHD): 500 built from 9/72 thru 1/73
3.2 injection (LHD): 110 built from 7/73 thru 10/73, 57 built from 1/74 thru 10/75
Where was the 3.0 CSL produced?
Like all 3.0-liter E9-series coupes, the 3.0 CSL was assembled at the Karmann Werkes in Rheine, Germany.
Does the 3.0 CSL have a unique serial number sequence?
All fuel-injected CSLs have a unique model code and serial number sequence. However, the original carbureted CSLs were based upon standard 3.0 CS production models and therefore have no unique model code but instead contain serial numbers within the normal 3.0 CS production sequence.
Drivetrain
What engines were fitted to the 3.0 CSL?
The engine used in the first version of the 3.0 CSL was entirely unchanged from the standard 2,985-cc M30 inline-6 found in the 3.0 S/3.0 CS models. With an 89mm bore, an 80mm stroke and dual Zenith carburetors, this unit produced 180 hp (DIN) at 6,000 rpm and 192 lb/ft of torque at 3,700 rpm.
The second version of the 3.0 CSL carried over this same basic engine configuration but the bore was increased very slightly to 89.25mm (for a new overall displacement of 3,003cc) and the twin Zenith carbureotrs were replaced by an electronically-controled Bosch fuel injection system. Horsepower increased to 200 hp (DIN) at 5,500 rpm and torque increased to 204 lb/ft at 4,300 rpm. Though these were identical outputs to the standard fuel-injected 2,985-cc unit found in the 3.0 Si/3.0 CSi models, the slightly larger displacement helped better suit the requirements of the competition version.
The final version of the 3.0 CSL utilized a further enlarged version of the fuel-injected M30 powerplant with a longer 84mm stroke for a new overall displacement of 3,153cc. Peak power and torque both increased slightly to 206 hp (DIN) at 5,600 rpm and 215 lb/ft at 4,200 rpm, respectively.
What transmissions were offered on the 3.0 CSL?
All 3.0 CSLs were equipped with the same Getrag four-speed manual gearbox found in other three-liter E9 coupes and utilized the same gear ratios: 3.855 (1), 2.20 (2), 1.40 (3), 1.00 (4). This was mated to a limited slip rear differential (25 percent locking) with an axle ratio of either 3.45:1 (carbureted model) or 3.25:1 (all fuel-injected models).
Chassis
How is the suspension of the 3.0 CSL different from that of the 3.0 CS/3.0 CSi?
Though made up of the same basic MacPherson strut/semi-trailing arm design as all E9 coupes, the CSL incorporates the following changes:
-Bilstein gas-pressurized shocks
-specific progressive-rate springs with 20mm reduced height
-increased camber (1.1-degree in the front, 1.0-degree in the rear)
NOTE: CSLs are not equipped with front or rear anti-roll bars
What kind of steering system is fitted to the 3.0 CSL?
Like all E9 coupes, the 3.0 CSL utilizes a ZF worm and roller steering system, though it is different in two respects: the overall ratio is slightly longer (18.9:1 versus 18.0:1) and it is not power assisted except as an option or when equipped with the available "City Package".
What kind of brakes are fitted to the 3.0 CSL?
The 3.0 CSL is equipped with the same 10.7-inch disc brakes on all four corners as the standard 3.0 CS/3.0 CSi models.
What size wheels and tires is the 3.0 CSL equipped with?
All 3.0 CSL models are fitted with Alpina 7x14-inch alloy wheels wearing 195/70VR14 tires (originally Michelin XWX).
Cosmetics
How does the exterior of the 3.0 CSL differ cosmetically from the standard 3.0 CS/3.0CSi?
The 3.0 CSL can be distinguished from its 3.0 CS/3.0 CSi counterparts by the following items:
-aluminum hood, doors and trunk lid
-chrome fender lip extensions
-black side stripe with the "3.0 CSL" logo
-racing-style pin release for the hood*
-lack of front bumper*
-lightweight (5.5 lbs.) plastic rear bumper without overriders*
-"Verbel" laminated windshield
-lightweight window glass*
-fixed rear side windows*
-lack of trunk lock and tool kit*
-Alpina 7x14-inch alloy wheels
*does not apply to most UK-spec right-hand drive examples or those with the City Package
In addition, the final 3.2-liter CSL models differed cosmetically from the earlier models by including the following:
-front airdam
-black rubber air guides on the front fenders
-steel trunk lid with plastic rear spoiler and rubber lip
-"3.0 CSL" decal in place of metal rear model badge
-tri-color stripes on side and front airdam (Chamonix and Polaris metallic cars only)
-removable "racing kit" consisting of an air guide above the rear window and large rear spoiler (16 percent less drag)
How does the interior of the 3.0 CSL differ cosmetically from the standard 3.0 CS/3.0CSi?
The interior of the 3.0 CSL can be distinguished from that of the 3.0 CS/3.0 CSi models by its unique three-spoke leather-wrapped steering wheel and Scheel sport seats in black cloth upholstery with black leatherette bolsters. In addition, the roof lining is also black.
What options were offered on the 3.0 CSL?
Though generally equipped to a minimal specification to retain the lightest curb weight, the 3.0 CSL could be fitted at extra cost with the following features: power front windows (including standard glass), tinted windows (including standard glass), velour carpeting, locking gas cap, air conditioning, headlight washer/wipers and passenger-side mirror.
What is the City Package?
A City Package was offered as an option on all 3.0 CSL models and fitted to the majority of right-hand drive cars sold in the UK. Designed to make the 3.0 CSL more usable as a daily driver, it consisted of the following items:
-steel body panels (not included on all examples)
-power steering
-standard 3.0 CS/3.0 CSi chassis components (including anti-roll bars)
-standard 3.0 CS/3.0 CSi front and rear bumpers
-standard 3.0 CS/3.0 CSi windshield
-standard 3.0 CS/3.0 CSi side glass
-rear-window defroster
-chassis undercoating
-interior hood release
-additional sound deadening
-retractable rear side windows (power-operated)
-tool kit on inner trunk lid
-trunk lock
-velour carpeting

E10 2002 Turbo
Production Versions:
2291: European-spec (LHD), 01/74-10/75
History
What makes the 2002 Turbo unique?
The 2002 Turbo is a forced-induction version of the 2002tii. It was developed by BMW Motorsport based on previous experience with turbocharging and supercharging in racing applications.
Is the 2002 Turbo considered an M car?
Though not officially labeled as an M car, the 2002 Turbo was developed by BMW Motorsport (later renamed BMW M). Like the 3.0CSL, it is therefore often considered a member of the M Series.
Production Data
Where was the 2002 Turbo produced?
Production of the 2002 Turbo occurred on the standard production line in Munich, Germany.
How many versions of the 2002 Turbo were produced?
All 2002 Turbos were built in left-hand drive and to European specification.
How many examples of the 2002 Turbos were built?
ECE (non-cat): 1,672 built from 01/74 thru 10/75*
*includes 12 pre-production examples produced 7/73 thru 12/73
What changed during the production of the 2002 Turbo?
Because the 2002 Turbo existed for a relatively short time, there were few changes during its production. Of note, however, is that the original stripes, with their reversed "obrut" script, were deleted not long after production began (see explanation under Cosmetics). Also, beginning with VIN 4291213, the side-mounted tailpipe was moved to the center in an effort to prevent rust around the rear valance panel.
Drivetrain
How does the 2002 Turbo’s engine differ from a 2002tii??
The 2002 Turbo’s engine was based on the M10 1990cc SOHC inline-4 with Kugelfischer fuel injection, as used in the 2002tii. However, a KKK turbocharger adapted from a light-duty truck application boosted power to 170 hp (DIN) @ 5,800 rpm and torque to 181 lb/ft @ 4000 rpm. The low-compression nature of turbocharged engines required special pistons, lowering the compression ratio to 6.9:1. The cylinder head was also redesigned, but the stock 2002 pistons were retained. The Kugelfischer fuel injection pump was similar to the 2002tii unit, but was modified internally.
What kind of gearboxes were offerred in the 2002 Turbo?
The standard 2002 Turbo transmission was a reinforced Getrag 232 four-speed manual with the following ratios: 3.76 (1), 2.09 (2), 1.32 (3), 1.00 (4).
Two versions of the close-ratio Getrag 235/8 five-speed manual gearbox were optional. The first included the following ratios: 2.72 (1), 1.84 (2), 1.38 (3), 1.13 (4), 1.00 (5). A second, beefier version used the following ratios: 2.91 (1), 1.97 (2), 1.48 (3), 1.21 (4), 1.00 (5).
A 3.36:1 final drive was standard with all gearboxes, though a shorter 3.45:1 could be ordered as an option. Both came mated to limited slip differentials (40% locking). There were also a number of BMW Motorsport differntials available (3.64, 3.91, 4.10, etc.), but these were intended for competition use only.
Chassis
How is the 2002 Turbo’s chassis different from a 2002tii?
The Turbo’s chassis was based upon that of the already competent 2002tii, with MacPherson struts in the front and semi-trailing arms in the back. The normal 2002 front springs were retained, as was the 16mm rear antiroll bar. However, the Turbo used a larger 20mm front antiroll bar (up from 15mm) and unique rear springs with three different spring pads to adjust the ride height. In addition, the Turbo was fitted with Bilstein shocks and had reinforced trailing arms, rear wheel bearings, hubs and stub axles.
What kind of brakes was the 2002 Turbo equipped with?
The 2002 Turbo used upgraded 10.08-inch front disc brakes and the stock 2002tii rear drums.
What were the factory wheels and tires for the 2002 Turbo?
All 2002 Turbos were fitted with 185/70VR13 tires. Two types of wheels were available: 5.5x13-inch steel wheels with dark gray centers were standard, with a disc-type 6x13-inch alloy wheel as an option.
Cosmetics
What exterior features are unique to the 2002 Turbo?
The 2002 Turbo is easily distinguished from any other 2002 by its body-color front spoiler, black rubber rear spoiler, and riveted fender flares. Some cars were further fitted with Motorsport stripes on the front spoiler and sides. However, underneath the surface there are more subtle changes: The front frame rails are heavier, the floor areas around the rear suspension mounting points are thicker, the quarter panels are cut out for the flares, the outer rear wheel housings are larger, the trunk floor is different to accommodate a larger spare tire and special 70-liter fuel tank, and the nose panel is unique.
Why were there two kinds of Motorsport stripes?
The original style of Motorsport stripes featured the word “turbo” in reverse on the front spoiler. This was designed so that drivers could see the word clearly in their rear-view mirror as the Turbo was quickly approaching. However, the German government considered this to be too outlandish and BMW was quickly pressured into changing to a different style without any kind of turbo script on the front spoiler.
What interior features are unique to the 2002 Turbo?
The interior of the 2002 Turbo is equipped with a three-spoke sport steering wheel, sport seats in black leatherette, a red instrument surround within the main cluster and a VDO boost gauge with analog clock mounted in a central pod above the dash.
What was optional on a 2002 Turbo?
The standard 2002 Turbo was sparsely equipped, thus many options were available. These included a five-speed manual gearbox, 6x13-inch alloy wheels, rear window defroster, laminated glass, rear seat belts, passenger-side exterior mirror, velour floor mats, lockable glove box, lockable gas cap, manual sunroof, power sunroof, front fog lights, rear fog light, headlight washer/wipers, tinted glass, radio with cassette player and the exterior Motorsport stripes.
Special Versions
Were there any special versions of the 2002 Turbo?
There were no special versions of the 2002 Turbo.
What makes the E12 M535i unique?
The E12 M535i is the only official BMW Motorsport-developed version of the E12 5 Series. It is the only E12 model powered by the 3.5-liter M30 inline-six from the E23 735i and E24 635CSi. It also has a BMW Motorsport-tuned chassis and several unique cosmetic items.
Where was the E12 M535i produced?
European-spec E12 M535i models were partially assembled on the normal 5 Series production line at Dingolfing then hand-finished at the BMW Motorsport facility on the Preussenstrasse in Munich. South African-spec versions were assembled in BMW's Rosslyn, South Africa factory from Complete Knock Down (CKD) kits supplied from Germany.
When was the E12 M535i introduced?
The E12 M535i was introduced at the 1979 Frankfurt motor show.
Why was the E12 M535i never officially sold in North America?
The E12 M535i was never officially sold in North America because the 3.5-liter M30 engine was not yet available with a catalyst and therefore could not meet U.S. emission control standards. Also, the addition of such equipment, as well as the various government-mandated safety items, would have reduced performance to essentially that of a North American-spec 528i.
Production Data
How many versions of the E12 M535i were developed?
Two versions of the E12 M535i were produced by BMW Motorsport GmbH exclusively for the European market, one in left-hand drive and another in right-hand drive. In addition, BMW of South Africa assembled its own right-hand drive version of the E12 M535i from German-supplied Complete Knock Down (CKD) kits. An updated M535i also existed as part of the "hybrid" E12/E28 range that was produced exclusively in South Africa between 1981 and 1984.
How many of each version were produced?
ECE (LHD): 950 built from 4/80 thru 5/81
ECE (RHD): 450 built from 7/80 thru 6/81
SA (RHD): 240 assembled from CKD kits from 2/81 thru 7/81
SA (RHD): 1,416 assembled from CKD kits from 9/81 thru 5/84*
*Special E12/E28 hybrid model. See Speical Versions.
Drivetrain
What kind of engine powers the E12 M535i?
The E12 M535i is powered by the early version of the M30 inline-six with a bore of 93.4mm and a stroke of 84.0mm for a total displacement of 3,453cc. This SOHC iron-block unit utilizes Bosch L-Jetronic fuel injection and produces 218 hp (DIN) at 5,200 rpm and 224 lb/ft of torque at 4,000 rpm. This engine was not offered with emission controls. Note: South African-spec models, though powered by essentially the same engine, are rated at 214 hp (DIN) and 229 lb/ft of torque.
What kind of gearboxes were available in the E12 M535i?
There were two different five-speed manual gearboxes fitted to the E12 M535i. All European-spec models were equipped with the Gertag close-ratio unit featuring a "dogleg" shift pattern and the following ratios: 3.72 (1), 2.40 (2), 1.77 (3), 1.26 (4), 1.00 (5). South African-spec model retained the more common overdrive Getrag transmission with the following ratios: 3.82 (1), 2.20 (2), 1.40 (3), 1.00 (4), .81 (5). All E12 M535i models were equipped with a 3.07:1 rear end with limited slip differential.
Chassis
How is the E12 M535i's suspension different from that of the standard E12 5 Series?
The basic suspension design of the E12 M535i is similar to that of all E12 5 Series models, with MacPherson struts in front and a semi-trailing arm design in the rear. However, it has been tuned by BMW Motorsport and is therefore equipped with unique springs and Bilstein shocks. Steering is by recirculating ball, with engine-speed-sensitive power assist and an overall ratio of 16.9:1.
What kind of brakes does the E12 M535i have?
Every E12 M535i has four-wheel disc brakes. The vented front rotors measure 11-inches (280mm) in diameter and are no larger than those fitted to other six-cylinder E12 models. However, at 25mm in thickness, they are 3mm thicker than all other E12 rotors. The solid rear rotors measure 10.7-inches (272mm) in diameter and are identical to those used on other E12 models. ABS was not available.
What are the factory wheel and tire sizes for the E12 M535i?
All E12 M535i models are fitted with 195/70VR14 tires but there were two different wheel options. All European-spec models are equipped with 6.5x14-inch BBS cross-spoke alloys while South African-spec versions use a slightly wider 7x14-inch version of a similar design made by BBS/Mahle. The latter also feature unique center caps bearing the BMW Motorsport logo.
Cosmetics
What distinguishes the exterior of the E12 M535i from that of a standard 5 Series?
The exterior of the E12 M535i can be identified by its unique body-color front airdam, black rubber rear spoiler and tri-color BMW Motorsport stripes on the side bodywork and front airdam. However, these items were technically listed as "special equipment" and could be omitted upon request in order to give the car the stealthy appearance of a standard 5 Series. In addition, the "M535i" grille and decklid badging could be deleted as well. However, the 14-inch cross-spoke alloy wheels were fitted to every M535i.
How is the exterior of the South African E12 M535i different from that of the German-built version?
The South African-spec M535i was not offered with the front airdam, rear spoiler or Motorsport stripes of the European-spec model. However, it was equipped with the "M535i" grille and decklid badging as well as a pair of large front foglights. It was also fitted with 7x14-inch BBS/Mahle cross-spoke alloy wheels featuring special center caps bearing the BMW Motorsport logo.
What distinguishes the interior of the E12 M535i from that of a standard 5 Series?
Though it shares its basic design and layout with that of the standard E12 5 Series, the interior of the E12 M535i contains two special features: Front sport seats made by Recaro in corduroy, leatherette or optional leather (or available ASS sport seats in black cloth with the Motorsport stripes) and a three-spoke leather-wrapped steering wheel featuring the BMW Motorpsort logo, identical to the one used in the M1 sports car.
How is the interior of the South African E12 M535i different from that of the German-built version?
The interior of the South African-spec E12 M535i is essentially identical to that of the German-built version, though it is fitted with additional standard equipment including air conditioning, power windows and central locking.
What features were optional on the E12 M535i?
The lengthy option list for the E12 M535i consisted of fog lights (not available with the front and rear spoilers), headlight washer/wipers, passenger-side rearview mirror, leather upholstery (or leatherette at no extra charge), ASS sport seats with Motorsport stripes, passenger seat height adjustment, velour floor mats, fire extinguisher, rear headrests, green tinted glass, brown tinted glass, air conditioning (including green-tinted glass), manual sunroof, power sunroof, power windows (all around or front only), central locking, various audio systems and a power antenna. In addition, the front airdam, rear spoiler and Motorsport stripes were listed as "special equipment," presumably at no extra charge. Note: Right-hand drive models (both ECE and South African) included many of these optional items as standard equipment.
Special Versions
Were there any special versions of the E12 M535i?
There were no official factory special editions of the E12 M535i. However, the M535i was not the first E12 model developed by BMW Motorsport GmbH. Through a special program offered soon after E12 production began, 5 Series sedans could be fitted by BMW Motorsport GmbH with the larger 3.0-liter and (later) 3.2-liter M30 inline-6 engines from the upmarket 6 Series and 7 Series models . Along with the "Motorsport Special Edition" E12 530 model, produced as a homologation special exclusively by BMW South Africa, these BMW Motorsport-built 5 Series were the unofficial predecessors to the E12 M535i. It is also worth noting that the M535i was included as part of the updated E12 range that was produced in South Africa prior to the introduction of the true E28 M535i in 1985.
What distinguishes the 3.0-liter and 3.2-liter E12 5 Series models built by BMW Motorsport?
Starting in 1974, the E12 5 Series could be equipped by BMW Motorsport GmbH with the three-liter M30 inline-six from the larger E3 sedans and E9 coupes in either carburetted or fuel-injected form. Later, the 3.2-liter version of the fuel-injected engine also became available. These cars were not separate models but were instead converted from standard 525, 528 or 528i sedans shipped from the normal BMW assembly line to the BMW Motorsport facility on the Preussenstrasse in Munich.
When fitted with these larger engines, the 5 Series sedans also received a shorter 3.45:1 rear axle ratio with limited slip differential, a revised exhaust system, Bilstein shocks, rear disc brakes, a reinforced rear axle and 195/70VR14 tires on 7x14-inch BBS cross-spoke alloy wheels with center caps bearing the BMW Motorpsort logo. Tri-color Motorsport stripes could be applied to the body as an option, and a BMW Motorsport three-spoke steering wheel and sport seats made by Recaro or Scheel were also available. It is thought that around 900 of these special E12 5 Series models were produced by BMW Motorsport over seven years.
What distinguishes the South African-built E12 530 Motorsport Special Edition?
The Motorsport Special Edition of the E12 530 was jointly developed by BMW of South Africa and BMW Motorsport GmbH in order to homologate the three-liter 5 Series sedan for competition in South Africa's Modified Production class. The production of at least 100 road cars was required under the homologation rules, though it is thought that around 200 street-legal examples of the Motorsport Special Edition 530 were ultimately produced, all in 1976.
At the time, the largest engine available in a standard production E12 5 Series was the 2.8-liter inline-six. However, the Motorsport Special Edition 530 was equipped with a larger three-liter motor based on the unit from the E3 sedan and E9 coupe but fitted with twin Zenith carburetors, a special camshaft, lightened flywheel and an engine oil cooler. It was rated at 197 hp (DIN) at 6,000 rpm and 204 lb/ft of torque at 4,300 rpm. This was mated to the close-ratio Getrag five-speed manual gearbox featuring a "dogleg" shift pattern and a Borg-Warner limited slip differential.
The chassis was upgraded with Bilstein shocks, stiffer springs and thicker anti-roll bars similar to those fitted to the German-built three-liter E12 5 Series models built by BMW Motorsport starting in 1974. In addition, the cars were equipped with four-wheel disc brakes and 195/70VR14 tires on BBS/Mahle cross-spoke alloy wheels.
All examples of the Motorsport Special Edition 530 were painted white with Motorsport stripes. The body featured fender lip extensions as well as fiberglass front and rear spoilers. In order to reduce weight, several body panels were made of aluminum or thinner steel, while the pedals and trunk hinges were drilled for further savings. Inside, these special 530s were fitted with Scheel sport seats covered in blue velour and equipped with a three-spoke sport steering wheel. Finally, the rear bench seat was mounted to a foam base in order to reduce weight even further.
What distinguishes the later South African-assembled E12/E28 "hybrid" M535i?
Though an E28-based successor to the original E12 M535i did not appear in German-built form until early 1985, an updated E12 M535i was introduced as part of the revised South African E12 5 Series range in the Fall of 1981. These special E12/E28 hybrid models mate the existing E12 bodywork with many of the improved chassis and interior features of the newer E28 (which were not produced in South Africa until 1985). Like the original E12 M535i, the updated model is powered by the older 3,453cc version of the M30 inline-six, rated at 214 hp (DIN) at 5,200 rpm and 229 lb/ft of torque at 4,000 rpm. This could be mated to either the overdrive or close-ratio version of the Getrag five-speed manual gearbox (as used on the German-built model), paired exclusively with the taller 3.07:1 final drive and limited slip differential. The M-Technic chassis is identical to that of the German-built E28 M535i, though the four-wheel disc brakes do not include ABS. Tires are metric-sized 200/60VR390 Michelin TRXs on 165mm x 390mm alloy wheels (also used on some non-M versions of the German-built E28 5 Series).
The early South African M535i shares all of its exterior body panels with the E12 5 Series and is not equipped with any special M-designed spoilers or trim. However, it is fitted with large front foglights, plus "M535i" grille and decklid badges, as seen on the E12 M535i.The interior blends the E28-style dashboard and instrument cluster with the E12-style door panels and seats, velour-covered Recaros in this case. It is also fitted with the early-style M steering wheel, as used in the E12 M535i and M1. The leather shift knob is also of the earlier E12 stlye, without the shift pattern on top. Standard equipment included air conditioning, power windows (front and rear), power mirrors, central locking, rear headrests, check control, and a radio/cassette audio system with four speakers. A power steel sunroof was optional.
BMW South Africa assembled 1,416 examples of the updated E12 M535i, known internally as model 4709, between September of 1981 and May of 1984. It was then replaced by a true E28-based successor to the E12 M535i in January of 1985.

E23 745i SA (M88)
Production Versions:
6928: South African-spec (RHD), 01/84-05/86
History
What makes the South African E23 745i unique?
The South African E23 745i is unique in that it is the only 7 Series model that is powered by the BMW Motorsport-designed 24-valve M88 powerplant also used in the E24 M635CSi coupe and E28 M5 sedan. This effectively makes it an "M7" in all but name. E23 745i models sold in the rest of the world use a turbocharged version of the 12-valve M30 engine instead.
Why was the M88-powered 7 Series not badged as an M7?
It is not entirely clear why the M88-powered 7 Series was not badged as an M7. It may have been because of BMW AG's policy (which continues to this day) of not bestowing any 7 Series model with a proper M badge. It may also be because BMW AG did not wish to upstage the turbocharged 745i sold in Europe, which was ultimately less powerful than the 24-valve version.
Why was the M88-powered E23 745i developed for South Africa?
After experimenting with various new V8 and V12 engines, BMW AG decided to use a turbocharged version of the existing SOHC M30 inline-six in its flagship E23 7 Series model. However, because of packaging restrictions caused by the addition of the turbocharger, this engine could not be fitted to right-hand drive cars.
Not content with selling a left-hand drive version of the 745i in a right-hand drive market, BMW of South Africa decided to instead to create a unique E23 variation powered by the 24-valve M88 engine already developed by BMW Motorsport for the E24 6 Series and E28 5 Series. Assembled in South Africa from Complete Knock-Down (CKD) kits, this special right-hand drive model was sold exclusively in the domestic market, though at least one example was subsequently exported to Europe.
Why is the M88-powered 745i unique to South Africa?
BMW has never officially stated why the German-built 745i models did not receive the M88 engine. The most likely explanation is that the M88 powerplant, developed originally for the M1 sports car, is a fairly noisy unit that develops its peak power at a relatively high engine speed. This was perhaps at odds with the role of the 7 Series as a refined luxury sedan, thus the smoother turbocharged unit was deemed more appropriate for use in 745i models sold in all other markets. In addition, it is unlikely that BMW could have produced enough M88 engines to satisfy demand, had the M motor been used in the German-built 745i.
Where was the South African E23 745i built?
Like all E23 7 Series sold in South Africa, the 745i was assembled in small numbers at BMW's Rosslyn, South Africa factory from Complete Knock-Down (CKD) kits supplied from Germany.
Production Data
How many versions of the M88-powered E23 745i were developed?
Just one version of the M88-powered 745i was developed, exclusively in right-hand drive for the South African market.
How many examples of the M88-powered E23 745i were built?
209 examples of the M88-powered 745i sedan were assembled by BMW South Africa from January 1984 thru May 1986. Of these, 17 were equipped with the manual transmission and the remainder were automatic.
What changes were made to the South African E23 745i during its producton?
With the exception of minor equipment alterations common to the entire E23 7 Series range such as an updated steering wheel design and improved on-board computer, there were no major changes to the South African 745i during the two and a half years that it was produced.
Drivetrain
What makes the M88 powerplant unique?
The M88 engine in the South African 745i is an evolution of the 24-valve inline-six developed for the mid-engine M1 supercar and is identical to the unit used in the non-catalyst versions of the E24 M635CSi and E28 M5. Like the 12-valve M30 engine upon which it is based, the M88 has a displacement of 3,453cc via a bore of 93.4mm and a stroke of 84mm. Unique to the M88 is the four-valve crossflow cylinder head (with 37mm inlet valves and 32mm exhaust valves) designed for better breathing at high rpm and a pair of 264-degree camshafts. With Bosch ML-Jetronic fuel injection system and a lack of smog controls, the M88 produces 286 hp (DIN) at 6,500 rpm and 251 lb/ft of torque at 4,500 rpm.
It is worth noting that the M88 engines fitted to early examples of the South African 745i are simply inscribed "BMW" on their cam cover in place of the later "M Power" designation shared with the E24 M635CSi and E28 M5.
What kind of gearboxes were offered on the South African-spec 745i?
Most examples of the South African-spec 745i were equipped with a computer-controlled ZF four-speed automatic transmission with Sport, Economy and Manual shift point modes mated to a 3.73:1 rear axle ratio and limited slip differential. Unlike the German-built 745i, the South African version was also offered with a Getrag five-speed manual gearbox with a "dogleg" shift pattern and the following ratios: 3.72 (1), 2.40 (2), 1.77 (3), 1.24 (4), 1.00 (5). These were equipped with a 3.45:1 rear end with limited slip.
Chassis
How is the South African-spec 745i's suspension different from that of the German-built version?
The suspension of the South African-spec 745i is slightly firmer than that of the European-spec model and a load-leveling rear axle is standard.
What size brakes does the South African-spec 745i have?
The South African-spec 745i is most likely equipped with the same brakes as the E24 M635CSi and E28 M5: 11.8-inch (300mm) vented discs in front and 11.2-inch (285mm) solid discs in the rear with standard ABS.
What size wheels and tires does the South African-spec 745i have?
The South African-spec 745i is fitted with BBS Mahle cross-spoke alloy wheels featuring special center caps bearing the BMW Motorsport colors. These measure 7x16-inch in front and 8x16-inch in rear and are fitted with staggered 205/55VR16 (front) and 225/50VR16 (rear) tires.
As an alternative, the South African-spec 745i could be ordered with the same metric-sized 165x390mm alloy wheels used on the German-built car, shod with 220/55VR390 Michelin TRX tires.
Cosmetics
How does the exterior of the South African-spec 745i differ from that of the German-built model?
The exterior of the M88-powered 745i is distinguished from other 7 Series models only by its 16-inch BBS Mahle alloy wheels. There are no M badges or any other special trim items on the exterior of the car.
How is the interior of the South African-spec 745i different from that of the German-built model?
Unlike the exterior, the interior of the M88-powered 745i contains many special features. The entire cabin including the dashboard, center console, door panels and headliner is covered in ultra-soft Nappa leather (later known as the "Highline" interior, this extensive leather option was not offered on German-built E23s until the final 1986 model year). The center console itself is shaped slightly differently than in other E23 models, with the power window switches located around the shifter instead of around the parking brake handle and the ashtray located behind the shifter instead of below the radio. On cars with an automatic transmission, the shift lever lacks the usual "PRND321" markings and is surrounded by a leather boot. Also unique to the South African-spec 745i is a special instrument cluster with the M logo on both the speedometer and tachometer faces though it appears that the M logo was removed from the speedometer face early into production. The leather-wrapped steering wheel is a three-spoke (non-M) design.
What features are included in the South African-spec 745i's interior?
The interior of every South African-spec 745i is equipped with essentially all available E23 features including power windows, power mirrors, power front seats, power rear seats, power glass moonroof (deletable upon request), automatic climate control, cruise control, check control, on-board computer, radio/cassette audio system and rear window sunshade.
Special Versions
Were there any special versions of the South African-spec 745i?
Essentially a special model in itself, there were no further special editions of the M88-powered 745i.
Color and Upholstery Selections
Exterior Colors
All standard 7 Series exterior colors for the South African market wrere offered.
Interior Colors
Complete ultra-soft Nappa leather covering the dashboard, center console, sun visors, door pulls, etc. in either Lotus White, Natur or Dark Blue.
What makes the M6535CSi/M6 unique?
The M635CSi and M6 are the BMW Motorsport-developed versions of the E24 6 Series. They use the M88 or S38 twin-cam 24-valve inline-six-cylinder engines first introduced in the M1. They also have a BMW Motorsport-tuned chassis and a few special cosmetic pieces.
What’s the difference between the M635CSi and M6?
All examples of the BMW Motorsport-developed E24 6 Series are known interanlly as the M635CSi. However, all North American versions were officially badged "M6", both to simplify the name and to bring it in line with the other M models, specifically the M3 and M5.
When was the M635CSi/M6 first introduced?
The M635CSi was introduced at the 1983 Frankfurt Motor Show.
Where was the M635CSi/M6 built?
Like all 6 Series, the M635CSi/M6 was built on the normal Dingolfing assembly line, with body shells shipped from the Karmann works in Osnabruck.
Production Data
How many versions of the M635CSi/M6 were developed?
BMW Motorsport developed five different versions of the M635CSi/M6: Two non-catalyst models for the European market (left-hand drive and right-hand drive), plus three distinct catalyst versions for Europe, North America and Japan (all left-hand drive).
How many of each version were produced?
ECE (LHD without cat): 3,283 built from 12/83 thru 12/88
ECE (RHD without cat): 524 built from 09/84 thru 02/89
ECE (LHD with cat): 117 built from 11/86 thru 12/88
NA (LHD with cat): 1,767 built from 09/86 thru 09/88
JAP (LHD with cat): 164 built from 09/86 thru 03/88
What changed during the production of the M635CSi?
There were few major mechanical changes during the five-year period that the M635CSi was produced, though certain items with known mechanical defects (valve springs, two-piece wheels) were updated during the course of production. In addition, the catalyst-equipped S38 engine became available as an option in some left-hand drive European markets starting with November 1986 production (two months after it became the standard M6 engine in North America). Also beginning in 1986, a fixed rear center console with integrated storage compartment and air conditioning unit became available in some markets and Shadowline (dechromed) exterior trim was added to the option list.
The biggest cosmetic changes occurred starting with June 1987 production. At this time, the slimmer chrome-trimmed bumpers were replaced with larger versions featuring body-color end caps. Also, ellipsoid headlights and foglights replaced the halogen units of earlier cars. The latter were part of a reshaped front airdam that was shared with the regular 635CSi. Finally, the shift knob was updated to the ergonomic design introduced a year earlier on the E32 7 Series, and the Highline complete Nappa leather interior, already standard on U.S.-spec M6s, became available as an option in other markets. (Note: All right-hand drive examples of the "big bumper" M635CSi have the Highline Nappa leather interior.) The final change occured in Spetember of 1988 when the power front seat controls were moved from the center console to the base of the seat itself.
How did these changes affect the North American M6?
Though there were no major mechanical alterations during the production of the North American M6, the are a number of cosmetic differences between M6s built before June of 1987 (1987 models) and those built after that date (1988 models). The 1987 models have large, government-mandated five-mph bumpers with black rubber trim and a unique front air dam that is similar to that of the 1985-87 North American-spec 635CSi, but with extra cooling ducts for the engine oil cooler. The 1988 model features the same updated bumpers, ellipsoid headlights and revised front airdam with flush-mounted foglights as the facelifted, European-spec M635CSi. It also has the ergonomic shift knob. U.S.-specification M6s built to 1988 specification are further fitted with a driver-side airbag with knee bolster, but lack the leather dashboard and upper door trim of the 1987 M6 Highline models (though they retain Nappa leather upholstery on the seats, center console, lower door panels, glovebox door, A-pillars, B-pillars, headliner and sun visors).
Drivetrain
What makes the M88/S38 engine unique?
The M88 and S38 engines are evolutions of the 24-valve inline-six developed for the mid-engine M1 supercar. Like that engine, both the M88 and S38 have a four-valve crossflow cylinder head (with 37mm inlet valves and 32mm exhaust valves) designed for better breathing at high rpm and a pair of 264-degree camshafts. They also share a displacement of 3,453cc via a bore of 93.4mm and a stroke of 84mm. However, for their application in the M635CSi/M6, the M88 and S38 have unique pistons and connecting rods, as well as a more advanced Bosch ML-Jetronic fuel injection system. To save costs, both engines utilize the standard steel M30 crankshaft and wet-sump lubrication system. Many other smaller items, such as the ignition system, are shared with the regular 6 Series as well.
How do the M88 and S38 engines differ?
The M88 is the non-catalyst version of the S38 engine. With a 10.5:1 compression ratio and a single-row timing chain, it is identical to the one found in Euro-spec E28 M5 sedans. Power is rated at 286 hp (DIN) at 6,500 rpm with 251 lb/ft of torque at 4,500 rpm. The M88 can be identified by the inscription on its cam cover: the propeller Roundel plus the words “BMW” or “M Power.”
The S38 is the “clean” version of the engine, introduced for North America but later offered in other markets as well. It utilizes a duplex (double-row) timing chain and lower 9.8:1 compression designed to work with catalytic converters. This reduced the horsepower to 256 hp (SAE) or 260 hp (DIN) at 6,500 rpm and torque to 243 lb/ft at 4,500 rpm. The S38 has the inscription “BMW M Power” on its cam cover but no Roundel.
What kind of gearbox does the M635CSi/M6 have?
All M635CSi/M6s have the Getrag 280/5 five-speed manual gearbox. Gear ratios are as follows: 3.51 (1), 2.08 (2), 1.35 (3), 1.00 (4), .81 (5). A 3.73:1 final drive is fitted to all but the North American M6, which uses a 3.91:1 rear end. All have limited slip differentials with a maximum locking of 25 percent.
Chassis
How is the M635CSi/M6's suspension different from the standard 6 Series?
All M635CSi/M6s use the MacPherson strut/semi-trailing arm suspension design common to all E24 6 Series. However, it has been tuned by BMW Motorsport in the following ways:
-Ride height reduced by 0.4 inches
-Increased steering caster
-Spring stiffness increased by 15 percent
-Progressive rate rear springs
-Specially-tuned Bilstein shocks
A self-leveling rear suspension was optional in some markets and standard on all North American-spec M6s.
How is the M635CSi/M6's steering different from the standard 6 Series?
The M635CSi/M6’s recirculating ball steering with ZF power assist is identical to the one used in the regular 635CSi and has an overall ratio of 15.7:1. Like the 635CSi, cars built for the final 1989 model year have vehicle-speed sensitive Servotronic power steering made by ZF.
What size brakes does the M635CSi/M6 have?
The M635CSi/M6 has enlarged vented front rotors that measure 11.8-inches (300mm) in diameter. These utilize four-piston calipers. The solid rear rotors, measuring 11.2-inches (284mm) in diameter, are the same as those found on the 635CSi. ABS is standard.
What are the factory wheel and tire sizes for the M635CSi/M6?
There were two available wheel and tire sizes for the M635CSi. Early European-spec cars used the standard 6 Series metric-sized wheels (390mm x 165mm) with 220/55VR390 Michelin TRX tires. However, optional from the start of production (standard in some markets) were larger, two-piece alloys in a cross-spoke design measuring 415mm x 195mm (16.3-in. x 7.7-in.). Cars with these wheels carry 240/45VR415 Michelin TRX tires. After the two-piece wheels showed signs of cracking, BMW switched to a similar one-piece cross-spoke design in the same size as part of the June, 1987 facelift. However, these wheels were also fitted to all North American M6s from the beginning of production.
Cosmetics
What distinguishes an M635CSi’s exterior from a regular 6 Series?
The M635CSi has few visual clues to distinguish it from the normal 6 Series. Almost all body panels are shared with other E24s, including the body-color rear spoiler with black rubber lip. The only exception is the deeper front airdam fitted only to pre-facelift models, which is ribbed on the lower portion. There are also two M badges, one on the trunklid and one on the grille, though these could be omitted upon request. In addition, the rear-view mirror housings are painted in body color instead of the chrome finish used on all other pre-facelift 6 Series. Finally, cars with the BBS-style cross-spoke wheels (in either the early or later version) have body-color fender lip extensions. After the mid-1987 facelift, the front airdam was changed to the same one fitted to all 6 Series, so the M635CSi could only be identified by its M badges (where fitted) and 415mm (16.3-inch) cross-spoke alloys, now standard and in a one-piece design. As with the 635CSi, Shadowline (dechromed) exterior trim became optional on the M635CSi during 1986 but only with limited exterior colors.
What distinguishes the exterior of the North American M6 from that of the M635CSi?
Cosmetically, all North American-spec M6s have unique grille and decklid badges with the “M6” logo. They also have a rear spoiler (not fitted by the factory to other North American 6 Series models) and the later one-piece metric-sized cross-spoke alloy wheels. Cars built for the 1987 model year (before June, 1987 production) have the bulky five-mph bumpers used on all 1978-87 6 Series in North America. The 1987 M6 also has a unique front airdam, with additional cooling slats. Cars built for the 1988 model year (6/87 and later) have ellipsoid headlights and a slimmer 2.5-mph bumper design that is visually identical to the European-spec M635CSi of the same vintage. The front airdam on these cars is also identical to the one used on all 1988-89 6 Series. All North American M6s have chrome (non-Shadowline) exterior trim.
What distinguishes an M635CSi’s interior from that of a regular 6 Series?
The interior of the M635CSi is much like that of all other 6 Series models. The only truely unique item is the instrument cluster, which contains a 280 kph/170 mph speedometer and a special tachometer with the M logo instead of an economy meter. In addition, every M635CSi is fitted with the three-spoke M-Technic steering wheel (unless equipped with the optional driver's airbag) and the same sport seats available in other 6 Series models. In some markets, these could be replaced by the wider "comfort" chairs, also shared with other 6 Series models. Finally, the battery of the M635CSi is mounted in the trunk for better weight distribution.
How does the interior of the North American M6 differ from that of an M635CSi?
The M6 interior differs little from that of the M635CSi. Like the European model, North American examples have the unique instrument cluster with a 280 kph/170 mph speedometer and a special tachometer with the M logo. However, they also have a generally higher level of standard equipment, including leather sport seats with power controls and driver’s side seat memory, power sunroof, cruise control, air conditioning, rear window sunshade and an eight-speaker am/fm cassette sound system. U.S.-spec cars are further enhanced by Nappa leather upholstery with either the Highline (1987 models) or Halfline (1988 models) interior trim and a rear center console/air conditioning unit. On 1988 models, a driver’s side airbag is also standard for U.S.-spec examples. Heated front seats were standard on the Canadian-specification M6 and the sole factory option on U.S models.
How exactly are U.S-specification and Canadian-specification M6s different?
All North American M6s are mechanically identical. They also have the same exterior appearance (with the exception of two additional exterior color choices for Canada). It is only on the inside that the U.S. and Canadian models can be distinguished from each other. The following are all the ways that the two versions differ, aside from having metric (Canada) or non-metric (U.S.) instrumentation:
U.S Specification:
Leather trim: Nappa Highline leather (1987) or Nappa Halfline leather (1988)
Rear console with A/C unit: Standard
Heated front seats: Optional
Driver’s side airbag with knee bolster: Standard (1988 models only)
Canadian Specification:
Leather trim: Regular leather on seats only
Rear console with A/C unit: Not available
Heated front seats: Standard
Driver’s side airbag with knee bolster: Not available
What are the Highline and Halfline interiors?
To add additional luxury to the M635CSi late in its product cycle, BMW introduced a Highline interior option as part of the mid-1987 facelift. It is worth noting that all left-hand drive facelifted examples are not necessarily Highlines, as they are often incorrectly referred to. In other words, there are a small number of left-hand drive facelifted cars without the Highline interior option.
The Highline interior includes hand-stitched Nappa leather on the seats, door panels, center console, glovebox door, headliner, sun visors, door pillars, upper door trim and dashboard. This interior was standard on all U.S-specification M6s built before June 1987, as well as all "big bumper" UK-specification M635CSi examples. In some other markets, the Highline interior could be ordered as an extra-cost option.
A special variation of the Highline linterior was introduced on all U.S.-specification M6s beginning with June 1987 production (1988 model year) after BMW of North America was forced to replace a significant amount of 1987 M6 leather dashboards that had been warped by the sun in warmer parts of the United States. Unofficially known as the "Halfline" interior, it included all the Nappa leather trim of the Highline interior except for the leather dashboard and leather upper door trim.
What features were optional on the M635CSi?
In general, the level of standard equipment increased on the M635CSi from year to year. Depending on the market and production date, options included: cross-spoke alloy wheels, metallic paint, Shadowline (dechromed) exterior trim, headlight washer/wipers, leather upholstery, air conditioning, rear air conditioning and storage unit, power front seats with driver's side memory, heated front seats, power sunroof, rear window sunshade, rear headrests, and various audio systems.
Special Versions
Were there any special editions of the M635CSi/M6?
There were no official special editions of the E24 M635CSi or M6. However, BMW United Kingdom offered an unofficial "Motorsport Edition" of the 1989 M635CSi in three special color and trim combinations: Misano Red (236) with Black Nappa Highline leather upholstery, Nogaro Silver metallic (243) with Black Nappa Highline leather upholstery and Macao Blue metallic (250) with Lotus White Nappa Highline leather upholstery. Produced in one consecutive batch of 23 examples between October of 1988 and February of 1989, the "Motorsport Edition" included all of the standard UK M635CSi equipment, plus Shadowline exterior trim and M stripe lapels on the front and rear seats.
Though not technically a special edition, the last two examples of the North American M6 ever produced are unique in that they were the only two made for the 1989 model year. Both VIN 2561766 (Alpine White II with Black leather) and VIN 2561767 (Salmon Silver with Black leather) were equipped to Canadian specification and feature the later E34-style power seat controls mounted directly to the seat instead of on the center console.

E26 M1
Production Versions:
5991: European-spec (LHD), 07/78-07/81
History
What makes the E26 M1 unique?
The E26 M1 is BMW's only mid-engine production sports car and the only product of BMW Motorsport GmbH that is not based on an existing production model from BMW AG. It has a two-seat GRP body designed by Giorgetto Giugiaro and a 24-valve version of the production M30 inline-six derived from the unit used in the 3.0CSL competition cars and known as the M88.
When was the E26 M1 introduced?
The E26 M1 debuted at the 1978 Paris motor show.
Why was the E26 M1 developed?
The E26 M1 was developed to 1) show that BMW Motorsport GmbH was a legitimate manufacturer of sports cars that could compete with Porsche and Ferrari on the street and 2) to offer a purpose-built machine that could participate competitively in the Group 4 and Group 5 racing series.
Why did the E26 M1 not compete in the Group 4 series?
Group 4 homologation requirements dictated that at least 400 examples of the street-legal verison of each competition machine had to be produced within 24 months. Due to the difficulties in securing a subcontractor to produce the M1 and the subsequent delay that this caused, the M1 was not officially homologated until April 1, 1981. Because the Group 4 homologation took several years longer than anticipated, BMW created the Procar Series in which identical Group 4-spec M1 racers competed in the hands of established Formula 1 and Touring Car drivers as well as privateers.
Production Data
How many versions of the E26 M1 were developed?
BMW Motorsport developed just one street-legal version of the E26 M1 in left-hand drive European specification. In addition, there were competition versions of the M1 built for Group 4 and Group 5, though the former were never homologated and subsequently became used in the M1 Procar series.
How many examples of the E26 M1 were produced?
There are many conflicting production numbers regarding the E26 M1, though it is clear that between 445 and 450 examples were produced in a three-year period between July 1978 and July 1981. Of these, between 46 and 50 are believed to be competition versions while the remaining 400 (approx.) examples constitute the road-going street cars. It is thought that the final street-legal M1 was produced in February 1981.
Where was the E26 M1 produced?
The E26 M1 project was approved by BMW AG in 1976 under the condition that it would not interfere with the production of any other BMW model. BMW Motorsport initially contracted Lamborghini to assemble the cars with engines produced and shipped from Germany. However, Lamborghini's severe financial troubles at the time forced them to terminate their agreement with BMW. Thus, the production examples of the E26 M1 were partially assembled at Ital Design in Turin using fiberglass bodywork supplied by T.I.R and tubular spaceframes supplied by Marchesi. Final assembly was then conducted in Stuttgart, Germany at the Baur coachworks.
What changes were made to the E26 M1 during its production?
There were no significant changes to the E26 M1 during the 32 months that it was produced.
Drivetrain
How is the M88 engine unique?
The M88 engine that powers the E26 M1 is based on the 3,453-cc (via a bore of 93.4mm and stroke of 84mm) M30 inline-six that powered the contemporary BMW 6 Series and 7 Series models of the era. However, the M88 received a number of unique components including:
-A four-valve cylinder head derived from the 3.0CSL racing engines. The head is made of two pieces, the lower part comprising the combustion chamber and coolant chamber, while the upper portion contains the camshaft bearings and cup tappets.
-Individual throttle bodies for each cylinder. Measuring 46mm each, this is the first production engine from BMW Motorsport to utilize them.
-Kugelficsher mechanical fuel injection
-Magneti-Marelli electronic ignition
-Dry sump lubrication
Tuned for street use, the M88 engine produces 277 hp (DIN) at 6,500 rpm and 239 lb/ft of torque at 5,000 rpm. Racing versions produced 470 hp for Group 4 (normally-aspirated) and up to 850 hp for Group 5 (turbocharged).
What kind of gearbox does the E26 M1 have?
The E26 M1 uses a ZF five-speed manual gearbox with a "dogleg" shift pattern and the following ratios: 2.42 (1), 1.61 (2), 1.14 (3), 0.846 (4), 0.704 (5). This is mated to a 4.22:1 rear axle with limited slip differential (40 percent locking).
Chassis
What kind of suspension does the E26 M1 utilize?
The E26 M1 utilizes essentially the same double-wishbone suspension configuration both front and rear. Designed by Gianpaolo Dallara at Lamborghini, it is comprised of MacPherson struts, height-adjustable Bilstein shocks and double unequal-legnth control arms. There is a 23mm anti-roll bar in the front and a 19mm anti-roll bar in the rear. The E26 M1 is equipped with non-assisted rack-and-pinion steering with 3.2 turns lock-to-lock.
What size brakes does the E26 M1 have?
The E26 M1 is equipped with four-wheel vented disc brakes manufactured by ATE. The front rotors are 11.8-inches in diameter while the rear rotors measure 11.7-inches. ABS was not offered.
What size wheels and tires is the E26 M1 equipped with?
The E26 M1 was fitted exclusively with Pirelli P7 tires, sized 205/55VR16 in front and 225/50VR16 in the rear. The Campagnolo wheels contain BMW Motorsport center caps and are unique to the M1. They are sized 7x16-inch (front) and 8x16-inch (rear) .
Cosmetics
How is the exterior of the E26 M1 unique?
The Giugiaro-designed bodywork of the E26 M1 is made of GRP (fiberglass) and shares no panels with any other BMW model.
How is the interior of the E26 M1 unique?
Except for some minor switchgear carried over from the E21 3 Series and E24 6 Series, the interior of the E26 M1 is also largely unique. The seats are specific to the M1 and are manufactured by Recaro. The dashboard and seat bolsters are covered in leather, while the inner portion of the seats, door panels and headliner are covered in a textured cloth. The three-spoke, leather-wrapped steering wheel with early BMW Motorsport logo in the center was later shared with the E12 M535i.
What features were included on the E26 M1?
All M1 street cars were fitted as standard with air conditioning, power windows, power mirrors and a Becker radio/cassette audio system.
What items were optional on the E26 M1?
There were no factory options for the road version of the E26 M1.
Special Versions
Were there any speical factory versions of the E26 M1?
There were no special factory versions of the E26 M1 road car.

E28 M5
Production Versions:
DC91: European-spec (LHD), 10/84-9/87
DC92: European-spec (RHD), 03/86-11/87
DC93: North American-spec (LHD), 11/86-11/87
DC98: South African-spec (RHD), 06/87-11/88
History
What makes the E28 M5 unique?
The E28 M5 is the BMW Motorsport-developed version of the E28 5 Series. It uses the M88 or S38 twin-cam 24-valve inline-six first introduced in the M1. It also has a BMW Motorsport-tuned chassis and a few special cosmetic pieces.
Where was the E28 M5 built?
Unlike the normal 5 Series models, M5s were hand-assembled at the BMW Motorsport facility in Garching, a suburb of Munich. Bodies were pressed at the normal Dingolfing factory, then sent to Garching where they were mated with the engine and interior trim. The only exceptions were the South African-spec cars, assembled at BMW's Rosslyn, South Africa factory from German-supplied Complete Knock Down (CKD) kits.
Where was the E28 M5 first introduced?
The M5 debuted at the 1985 Amsterdam Motor Show.
Why was BMW sued by American E28 M5 owners?
When BMW of North America first anounced the E28 M5 in late 1986, production was said to be limited to 500 cars. But by the time production ended in November 1987, however, almost triple that number had been produced. Thus, a class action lawsuit was filed against BMW by E28 M5 owners who claimed that the collector's value of their cars was diminished by the greater volume. The company settled the case by giving these owners a rebate on the purchase of a new BMW.
Why are all North American-spec E28 M5s officially 1988 models if the last example was made in 1987?
This was most likely a marketing decision. With the M5 originally intended to be a limited edition of 500 cars, and with the entire E28 range due to be replaced by the E34 for 1989, perhaps BMW of North America wanted to keep the E28 M5 exclusive by offering it only for the final 1988 model year. Also, it is worth noting that production of the other 1988 5 Series models began in early 1987, so the M5 preceeded these by only a few months.
Why are all North American E28 M5s essentially identical?
Because the E28 M5 was hand-assembled, yet needed to be manufactured for the North American market in relatively large numbers within a relatively short amount of time, BMW of North America was forced to limit the model's specification to just two color schemes: Black (086) with a Natur (tan) leather interior and (officially for Canada only) Black (086) with a black leather interior.
Why is a North American E28 M5 with a black leather interior so rare?
Though a Natur (tan) leather interior was the only official color choice for the U.S. market, Canada insisited on giving E28 M5 buyers the option of a black leather interior. Because all cars for North America (Canada and the U.S.) are built to one specification aside from minor details like metric or non-metric instrumentation, some U.S. dealers were able to special order the black interior. However, it is thought that less than 50 North American M5s with a black interior were produced.
Production Data
How many versions of the E28 M5 were developed?
BMW Motorsport built four different versions of the E28 M5, three at the M works in Garching, Germany (European-spec in left-hand drive and right-hand drive, plus the North American version) and a South African-spec model for the home market assembled from Complete Knock Down (CKD) kits. Only the North American version utilized the catalyst-equipped S38 version of the M88 motor.
How many of each version were produced?
ECE (LHD): 588 built from 10/84 thru 9/87
ECE (RHD): 187 built from 3/86 thru 11/87
NA (LHD): 1,370 built from 11/86 thru 11/87
SA (RHD): 96 assembled from CKD kits from 6/87 thru 11/88*
*Figures indicate final completion date of vehicles assmebled in Rosslyn, South Africa.
Does every example of the E28 M5 utilize a "WBS" VIN prefix?
Starting with the E28 M5, all products from BMW Motorsport GmbH were assigned a "WBS" VIN prefix to distinguish them from the non-M BMW AG vehicles, which retained a "WBA" prefix. However, it is believed that the first 27 left-hand drive ECE examples of the E28 M5 were produced with the regular WBA prefix.
Drivetrain
What makes the M88/S38 engine unique?
The M88 and S38 engines are evolutions of the 24-valve inline-six developed for the mid-engine M1 supercar. Like that engine, both the M88 and S38 have a four-valve crossflow cylinder head (with 37mm inlet valves and 32mm exhaust valves) designed for better breathing at high rpm and a pair of 264-degree camshafts. They also share a displacement of 3,453cc via a bore of 93.4mm and a stroke of 84mm. However, for their application in the E28 M5, the M88 and S38 have unique pistons and connecting rods, as well as a more advanced Bosch ML-Jetronic fuel injection system. To save costs, both engines utilize the standard steel M30 crankshaft and wet-sump lubrication system. Many other smaller items, such as the ignition system, are shared with the regular 5 Series as well.
How do the M88 and S38 engines differ?
The M88 is the non-catalyst version of the S38 engine. With a 10.5:1 compression ratio and a single-row timing chain, it is identical to the one found in the M635CSi coupe. Power is rated at 286 hp (DIN) at 6,500 rpm with 251 lb/ft of torque at 4,500 rpm. The M88 can be identified by the inscription on its cam cover: the propeller Roundel plus the words “BMW” or “M Power.”
The S38 is the “clean” version of the engine, exclusively available in the E28 M5 in North America. It utilizes a duplex (double-row) timing chain and lower 9.8:1 compression designed to work with catalytic converters. This reduced the horsepower to 256 hp (SAE) or 260 hp (DIN) at 6,500 rpm and torque to 243 lb/ft at 4,500 rpm. The S38 has the inscription “BMW M Power” on its cam cover but no Roundel.
What kind of gearbox does the E28 M5 have?
All E28 M5s have the Getrag 280/5 five-speed manual gearbox. Gear ratios are as follows: 3.51 (1), 2.08 (2), 1.35 (3), 1.00 (4), .81 (5). A 3.73:1 final drive is fitted to all but the North American E28 M5, which uses a 3.91:1 rear end. All have limited slip differentials with a maximum locking of 25 percent.
Chassis
How is the suspension of the E28 M5 different from that of a standard 5 Series?
All M5s use the MacPherson strut/semi-trailing arm chassis design common to all E28 5 Series. However, it has been upgraded by BMW Motorsport in the following ways:
-Shorter, stiffer progressive-rate coil springs (not fitted to the North American version)
-Increased steering caster
-Specially-tuned Bilstein shocks
-25mm (front) and 18mm (rear) anti-roll bars
A self-leveling rear suspension was optional in some markets and standard on all North American-spec M5s.
What size brakes does the E28 M5 have?
The E28 M5 has enlarged vented front rotors that measure 11.8-inches (300mm) in diameter. These utilize four-piston calipers. The solid rear rotors are the same as those fitted to an E28 535i or M535i, measuring 11.2-inches (284mm) in diameter. ABS is standard.
What are the E28 M5's factory wheel and tire sizes?
There were two available factory wheel and tire sizes for the E28 M5. Early European-spec cars have metric-sized wheels measuring 195mm x 390mm with 220/55VR390 tires. Later European-spec examples, as well as all those sold in North America and South Africa, have 7.5x16-inch cross-spoke alloy wheels with 225/50VR16 tires, usually Pirelli P700s.
Cosmetics
What distinguishes the exterior of a European-spec E28 M5 from that of a normal 5 Series?
Because the intention of BMW Motorsport was to hide the performance capabilities of the M5 within a standard-looking 5 Series body, there are few external items that differentiate the European-spec E28 M5 from any other E28 sedan. The only body panel that is unique is the black plastic front airdam, included to reduce front end lift at high speeds. There is also an M5-specific aerodynamic engine compartment undertray, body-color rear-view mirror housings and a pair of "M5" badges, one on the grille and another on the trunk-lid, though these could be omitted upon request (which was common). Early examples wear metric-sized alloy wheels (exclusive to the M5 within the E28 series but also offered on the E24 6 Series and E23 7 Series) while most later cars have unique 7.5x16-inch cross-spoke alloys that also include body-color fender lip extensions. Shadowline (dechromed) exterior trim for the window surrounds, bumpers and side moldings was optional.
Later cars were also offered with the M-Technic aerodynamic package as an option. This consisted of body-color extensions with ribbed trim (front bumper and lower airdam, side valance panels, rear bumper and lower diffuser), a rear spoiler and dechromed side moldings. This option could be ordered with or without Shadowline trim but always included the16-inch cross-spoke alloy wheels and body-color fender lip extensions.
How is the interior of an E28 M5 different from that of a regular 5 Series?
Though identical in basic design and layout to that of any E28 5 Series, the interior of the E28 M5 is fitted with a few special items. All examples have a three-spoke M-Technic steering wheel also used in other BMW models. Most are also equipped with sport front seats, though a few were fitted with the standard "comfort" versions by request and some even had genuine Recaro front seats in place of the BMW items. In some markets, both the front and rear seats include an M tri-color stripe attached to a metal tag. On the earliest cars, the leather shift knob is topped with only an "M" logo. This was soon changed to a version with both the standard shift pattern and the tri-color M stripe. The instrument cluster contains a unique 280 kph/170 mph speedometer and a special tachometer with the M logo instead of an economy meter. A black headliner is exclusive to the M5 within the E28 range and later examples also have special door sill plates with the "M5" logo. Finally, the trunk of the E28 M5 is unique for four reasons. First, it contains the battery in a special right-side compartment, secured by one of two different covers, depending on the production date. Second, it is lined with a plush carpet. Third, with the exception of the earliest examples, the lining on the inside of the trunk lid is black instead of the usual light grey. Finally, there is a special cargo net to secure loose objectrs, though this also does not appear to have been fitted to the earliest cars.
What features were optional on the European-spec E28 M5?
Because the E28 M5 was assembled largely by hand at the BMW Motorsport facility, European customers could not only choose from the entire range of normal E28 options but also request more specialized features like hand-stitched complete leather interiors and/or integrated electronics such as phones, faxes, and minibars. Thus, depending on the market and production date, the E28 M5 could be very sparsely equipped or extremely luxurious. However, every E28 M5 features power front windows, power mirrors, central locking, and the Check Control vehicle function monitoring system. Options varied from market to market but generally included metallic paint, Shadowline (dechromed) exterior trim, headlight washer/wipers, leather upholstery (in various grades), air conditioning, the on-board computer II, power front seats, heated front seats, power sunroof, rear window sunshade, rear headrests and various audio systems.
How is a North American-spec E28 M5 cosmetically different from a Euro-spec E28 M5?
The North American-spec E28 M5 uses the same government-mandated sealed-beam headlights (all four of the same diameter) and 5-mph bumpers with integrated side marker lights as all U.S. and Canadian versions of the E28 5 Series. However, the M5 adds a special front airdam designed specifically for the North American front bumper as well as the M-Technic rear spoiler fitted as an option to some European-spec examples. Though these items are not unique to this model (both are also found on the E28 535is), the M5 can further be identified by its Shadowline trim, "M5" grille and trunk-lid badges plus the 16-inch cross-spoke alloy wheels.
How is the interior of the North American E28 M5 different from that of the European version?
Unlike the wide variation of color, trim and equipment found in European-spec E28 M5s, all North Americans-spec interiors have Black or Natur leather sport seats, with additonal hide on the seats, center console, glovebox door and door pulls. In addition, all have the M tri-color seat stripes (front and rear) and "M5" door sill plates, while the carpeted trunk always features the black lid lining, cargo net, later-style battery box enclosure and left-side storage compartment. Standard equipment includes air conditioning, power seats, power sunroof, cruise control and an eight-speaker am/fm cassette stereo system. Heated front seats were the only factory option (standard in Canada).
Special Versions
Were there any special versions of the E28 M5?
There were no special editions of the German-built E28 M5. However, a limited run (96 cars) of M5s was assembled in South Africa exclusively for that market.
What distinguishes the South African E28 M5 from the German-built version?
The 96 right-hand drive E28 M5s produced for the South African market were assembled at the Rosslyn, South Africa factory using German-made Complete Knock Down (CKD) kits. The mechancal items are thus identical to those of the European-spec E28 M5.
Cosmeticaly, however, the South African E28 M5 is somewhat unique. All are equipped with the M-Technic body panels that could be ordered as an option in some European markets, as well as Shadowline trim and the 7.5x16-inch cross spoke alloy wheels. But because the South African E28 M5s were painted in the local paint shop, exterior colors were limited to five choices: Henna Red (052), Ice White (?), Cirrus Blue metallic (189), Delphin Gray metallic (184) and Diamond Black metallic (181).
On the inside, all South African E28 M5s have essentially every normal 5 Series luxury item as standard, the only optional extra being a power sunroof. Unique to the South African version is a complete “Highline” Nappa leather interior normally offered only in E24 6 Series and E23 7 Series models. This includes Nappa leather on the seats, door panels, center console, glovebox door, headliner, sun visors, upper door trim and dashboard. There are also the usual M tri-color insignias on the front and rear seats. This interior was available in Lotus (white), Natur (tan), Midsilver (gray) and Indigo (dark blue). Finally, South African-spec models are not equipped with the black inner trunk lid liner used on all but the earliest German-built E28 M5s, though they do utilize the black trunk carpeting.

E30 320is (S14)
Production Versions:
AK95: Italy and Portugal-spec two-door, 03/88-11/90
AC95: Italy and Portugal-spec four-door, 09/87-07/90
History
What makes the E30 320is unique?
The E30 320is is a special 3 Series model that was sold exclusively in Italy and Portugal in order to take advantage of the reduced taxes in those countries for cars with engines that displace two liters or less. It is powered by a 1990cc version of the four-cylinder S14 engine developed by BMW Motorsport for the E30 M3 and also shares its close-ratio Getrag gearbox with the M3. However, all other components are standard 3 Series items.
Where was the E30 320is built?
The E30 320is was built on the normal Regensberg assembly line alongside the other 3 Series models.
If the E30 320is is powered by an M engine, why is not badged as an M model?
The reason the E30 320is is not badged as an M model ultimately comes down to marketing: Unlike the limited-production M3, which was created primarily as a competition machine and utilizes many unique exterior body panels and chassis components, the 320is was never intended to be a homologation special. It was conceived instead as a sportier and more affordable alternative to the torquier and more refined 325i, which was taxed heavily in Italy and Portugal due to its 2.5-liter engine.
Production Data
How many versions of the E30 320is were developed?
BMW developed the E30 320is only in non-catalyst, left-hand drive form and exported it exclusively to Italy and Portugal. Both two-door and four-door body styles were offered.
How many of each version were produced?
Two-door: 2,540* built from 03/88 thru 11/90
Four-door: 1,206 built from 09/87 thru 07/90
*includes one pre-production example produced 11/87
What changed during the production of the E30 320is?
There were no mechanical changes to the E30 320is during the three years that it was produced. However, there were a number of minor cosmetic and equipment variations that also apply to every E30 3 Series model built during the same period.
Drivetrain
What makes the two-liter S14 engine unique?
The two-liter S14 engine in the E30 320is is essentially identical to the 2,302cc version found in the E30 M3 except for its shorter stroke (72.6mm versus 84mm) that yields an overall displacement of 1,990cc. Like all S14 engines, it combines the basic four-cylinder block from the M10 family with a four-valve head derived from the one used on the six-cylinder M88 and S38 motors. Special features of this engine include individual throttle plates for each cylinder, machined intake and exhaust ports, and a crankshaft with eight counterweights. Like the M88 and S38, the S14 does not have hydraulic lifters, and thus requires periodic valve adjustments.
The two-liter S14 is rated at 192 hp (DIN) at 6,900 rpm and 155 lb/ft of torque at 4,900 rpm. This is down slightly compared to the non-catalyst, 2.3-liter S14 used in the E30 M3 which is rated at 200 hp (DIN) at 6,750 and 176 lb/ft of torque at 4,750 rpm.
The S14 engine fitted to the 320is has an identical appearance to the unit found in the E30 M3 and thus shares the "BMW M Power" inscription on its cam cover.
What kind of gearbox does the E30 320is have?
Like the European-spec E30 M3, the sole gearbox for the E30 320is is a close-ratio Getrag 260 five-speed manual with a "dogleg" shift pattern and the following ratios: 3.72 (1), 2.40 (2), 1.77 (3), 1.26 (4), 1.00 (5). This is mated to a shorter (compared to the M3) 3.46:1 rear axle ratio with limited-slip differential.
Chassis
How is the suspension of the E30 320is different from that of a standard E30 3 Series?
Like all E30 3 Series, the suspension of the 320is consists of a MacPherson strut/semi-trailing arm design.However, the springs, shocks and anti-roll bars of all two-doors (as well as four-doors produced from 9/89) are of the more aggressive "Sportfahrwerk" specification.
What kind of steering does the E30 320is have?
The 320is uses the standard E30 power-assisted rack-and-pinion steering system with an overall ratio of 20.5:1.
What size brakes does the E30 320is have?
The E30 320is shares its braking system with the six-cylinder E30 models and thus is equipped with 10.2-inch (260mm) vented disc brakes in the front and 10.2-inch (260mm) solid disc brakes in the rear. ABS was fitted as standard equipment.
What are the factory wheel and tire sizes for the E30 320is?
The E30 320is is equipped exclusively with 195/65VR14 tires. These are mounted to one of two different alloy wheel designs, both of which were shared with other E30 3 Series models: The 6.5x14-inch cross-spoke wheel (standard on the two-door) or the more plain 6x14-inch alloy (standard on the four-door).
Cosmetics
How is the exterior of the E30 320is different from that of a regular 3 Series?
The exterior of the 320is can only be identified from other E30 3 Series models by its "320is" badging on the trunk lid, though this could be deleted upon request. (The curved dual exhaust tips are also unlike those of any other four-cylinder 3 Series but are shared with the six-cylinder E30 325i.
The exterior of the four-door E30 320is is otherwise the same as any basic E30 sedan, equipped as standard with only fog lights and 14-inch alloy wheels. However, front and rear spoilers, Shadowline (dechromed) exterior trim, plus the sportier 14-inch cross-spoke alloy wheels, were offered as extra-cost options.
The two-door version of the E30 320is is further equipped with the complete M-Technic II aero package (identical to the one fitted to the UK-spec 325i Sport and available as an accessory on all other E30 3 Series models), which consists of a deeper front airdam, additional lower side body panels, an extended valance under the rear bumper and a two-piece rear spoiler. In addition, the two-door E30 320is sports body-color rearview mirror housings, Shadowline (dechromed) window trim and 14-inch cross-spoke alloy wheels.
How is the interior of the E30 320is different from that of a regular 3 Series?
The interior of the E30 320is is identical to that of other 3 Series models with the sole excpetion of its unique instrument cluster that utilizes the same tachometer with integrated oil temperature gauge as the E30 M3, but lacks the red needles and M logo between the two main dials. Also, the gear shift knob is of the older non-ergonomic design that was phased out on other E30 3 Series models (with the exception of the M3) in September, 1987.
The interior of the four-door E30 320is is quite Spartan, offering only the basics such as power mirrors, central locking, power front windows and a rear-window defroster as standard equipment. The two-door model adds map lights in the rear view mirror, sport seats, a three-spoke leather-wrapped M-Technic steering wheel and a leather shift knob, all of which were also available on the four-door as extra-cost options.
Factory options for both two-door and four-door versions of the 320is included: air conditioning, manual sunroof, power sunroof, interior headlight adjustment, BMW Sound System, heated front seats, digital clock with outside temperature display, on-board computer, rear headrests, rear sunshade and leather upholstery.

History
What makes the E30 M3 unique?
The E30 M3 is the BMW Motorsport-developed version of the E30 3 Series. Its S14 four-cylinder powerplant is a further development of the M10 unit and was chosen because of its compact dimensions. The chassis is based on the basic E30 3 Series design but has been thoroughly reworked by BMW Motorsport in every significant area. The reshaped body shares few panels with other E30 3 Series models.
Where was the E30 M3 first introduced?
The E30 M3 debuted at the 1985 Frankfurt motor show.
Where was the E30 M3 produced?
Because of the relatively high production numbers required to homologate the M3, production took place at the normal Munich-Milbertshofe factory instead of in the more limited Motorsport facility in Garching. However, unlike the normal E30 models, the M3's drivetrain was assembled by special teams, then mated to the chassis on the regular assembly line.
Why is the E30 M3 considered a homologation model?
The main impetus for the E30 M3’s existence was Group A racing, a production-based class that demanded that each race car share its core mechanical components with a road car, of which at least 5,000 examples had to be produced. Thus, BMW Motorsport designed the race car first, then applied the necessary changes to the road car in order to homologate the competition machine. The E30 M3 street version and E30 M3 competition version are therefore quite similar. For example, the widened fenders were needed to accommodate racing rubber on the competition cars but were not necessary for the more modest tires of the street version. However, fender width had to be identical between the road and race versions, so both share the same flared arches.
Production Data
How many versions of the E30 M3 were developed?
BMW Motorsport developed seven versions of the E30 M3 coupe, each with slight mechanical variations and all in left-hand drive. Four were regular production models: European-spec without catalyst, European-spec with catalyst in 195 hp (early) and 215 hp (later) forms, and North American-spec. The remaining three were limited editions known as the Evolution I, Evolution II and Sport Evolution. These were built to homologate updates to the engine and aerodynamics for racing purposes. There were also four further special editions with mainly cosmetic variations: Tour de Corse, Europa Meister 88, Johnny Cecotto and Roberto Ravaglia. In addition to the coupe, an E30 M3 convertible (see specific FAQ) was assembled by hand in limited numbers.
How many of each version were produced?

Do all examples of the E30 M3 utilize the "WBS" VIN prefix?
The E30 M3 was generally given a "WBS" VIN prefix (i.e. the first three letters in the VIN) to identify it as a product of BMW Motorsport GmbH. However, it is believed that the initial 164 ECE non-catalyst examples of the E30 M3 were given the regular WBA (non-M) prefix. The WBA prefix also appears in the VIN of the first 208 examples of the E30 M3 Sport Evolution.
What changed during the production of the European-spec E30 M3?
In addition to the development of several special edition models, there were many major and minor improvements made to the standard European-spec E30 M3 during the five and a half years it was produced. The most noteworthy of these occurred when both the 200-hp (non-catalyst) and 195-hp (catalyst) engines were replaced by the more powerful, catalyst-equipped 215-hp engine in September of 1989. Other changes include a switch to ellipsoid headlights with integrated "city" lights (from 9/87 production) and aluminum front control arms (6/89 production), the availability of Boge Electronic Damping Control and a myriad of minor color, trim and option variations.
What changed during the production of the North American-spec M3?
The E30 M3 was introduced in North America as a 1988 model, though production began in March of 1987. Cars produced before September of 1987 were actually built to 1987 specification (despite being officially considered "1988" models). True 1988 production began in September of 1987, when ellispoid headlights were introduced, Henna Red (052) was replaced by Cinnabar Red (138), Pearl Beige leather was replaced by Natur leather, and Silver leather was offered for the first time. An upgraded radio with CD-changer capability was introduced for the 1989 model year (from 7/88 production).
The next major round of changes were introduced with the 1990 model year (from 6/89 production). At this time, the ellipsoid headlights were once again replaced by halogen units, the rear quarter windows were fixed, the control arm bushings were modified, aluminum control arms replaced the steel versions and the air intake box was enlarged (as fitted to the Euro-spec Evolution II). In addition, the option list was expanded to inlcude a power glass moonroof and heated front seats (already standard in Canada). Further changes were implemented in September of 1989, when a driver-side airbag with knee bolster became standard (U.S.-spec cars only), plus Cinnabar Red (138) and Salmon Silver (203) were replaced by Brilliant Red (308) and Sterling Silver (244). The final 1991 models entered production in June of 1990 with no significant changes.
Drivetrain
What makes the S14 engine unique?
The E30 M3’s S14 engine was designed for racing applications and is therefore compact and high-revving. It combines the basic four-cylinder block from the M10 family with a four-valve head derived from the one used on the six-cylinder M88 and S38 motors. Special features of this engine include individual throttle plates for each cylinder, machined intake and exhaust ports, and a crankshaft with eight counterweights. Like the M88 and S38, the S14 does not have hydraulic lifters, and thus requires periodic valve adjustments.
How many versions of the S14 engine are there and how are they different?
BMW Motorpsort built five road-going versions of the S14 powerplant. The “standard” S14 engine has a bore of 93.4mm and a stroke of 84mm for a total capacity of 2,302cc. Without pollution controls, it is rated at 200 hp (DIN) at 6,750rpm and 176 lb/ft of torque at 4,750 rpm. A version of this engine equipped with twin in-line catalytic converters produces 195 hp (DIN) or 192 hp (SAE) and 170 lb/ft of torque at the same engine speeds. This was the only variation of the S14 sold in North America.
A second catalyst-equipped version of the S14 was introduced on the E30 M3 Cecotto/Ravaglia special editions in April, 1989. This engine produces 215 hp (DIN) at 6,750 rpm and 170 lb/ft of torque at 4,600 rpm. The increased power is largely due to a reprogramming of the Bosch Digital Motor Electronics (DME). This engine also became the standard European-spec E30 M3 engine as of September, 1989 production.
The most powerful evolution of the 2.3-liter S14 was introduced in the M3 Evolution II starting in March, 1988. Changes included new pistons that raised the compression to 11:1 (from 10.5:1), a more effecient air intake, lightened flywheel and reprogrammed engine management. This non-catalyst powerplant is rated at 220 hp (DIN) at 6,750 rpm and 181 lb/ft of torque at 4,750 rpm. These engines have white cam covers with the tri-color Motorpsort logo painted on them.
The final version of the S14 features increased cylinder bore (to 95mm) and a long-stroke crank for a new total displacement of 2,467cc. This engine was used exclusively in the 1990 E30 M3 Sport Evoltuion, built from 12/89 to 03/90. In addition to the increased displacement, the valves were enlarged and a more aggressive cam was fitted. Special nozzles sprayed oil under the pistons to keep them cool. All Sport Evolution motors were equipped with catalysts. Power increased to 238 hp (DIN) at 7,000 rpm, though peak torque decreased slightly (over the Evolution II) to 177 lb/ft at 4,750 rpm. These engines use the regular black cam cover but have red spark plug wires.
What kind of gearbox does the E30 M3 have?
Two different Getrag 260 five-speed manual gearboxes were used; a close-ratio version with a direct top gear and a “dogleg” shift pattern for Euro-spec cars, and an overdrive unit (shared with the E30 325i) with a standard “H” layout for North American-spec cars. The ratios are as follows:
European-spec: 3.72 (1), 2.40 (2), 1.77 (3), 1.26 (4), 1.00 (5)
North American-spec: 3.83 (1), 2.20 (2), 1.40 (3), 1.00 (4), 0.81 (5)
North American-spec cars have a shorter 4.10:1 final drive (versus 3.25:1) to offset the taller ratios. Both gearboxes are mated to limited slip rear differentials with a maximum locking of 25 percent.
What distinguishes a Euro-spec E30 M3 mechanically from a North American version?
Except for a different air intake arrangement, the North American-spec E30 M3 carries essentially the same powerplant as the early catalyst-equipped European-spec model. It is rated at 192 hp (SAE) at 6,750 rpm, which translates to a European rating of about 195 hp (DIN). Torque is an identical 170 lb/ft at 4,750 rpm. The only significant powertrain difference concerns the gearbox, which is a Getrag 260 with a standard shift pattern, as opposed to the European-spec model’s close-ratio Getrag box with its dogleg first gear location. The use of the conventional shift gate was determined to be more easily acceptable to Americans, and the wider ratios (shared with the E30 325i) are offset by a shorter 4.10:1 final drive.
Chassis
How is the M3's suspension different from that of a standard E30 3 Series?
The E30 M3’s chassis consists of the MacPherson strut/semi-trailing arm design used on all E30 3 Series model, but has been revised with the following changes:
-Three times more steering castor
-Front antiroll bar linked to the struts
-Stronger wheel bearings (from E28 5 Series)
-Thicker 19mm rear antiroll bar
-Shorter (by .6mm), stiffer springs
-Wider track
-Revalved shocks
Starting sometime in 1988, Euro-spec E30 M3s were available with Electronic Damper Control by Boge. This offered three shock stiffness settings, Komfort (K), Normal (N) and Sport (S) in order of increasing firmness, adjusted via a control knob in the center console.
How is the M3's steering different from that of a standard 3 Series?
Like all E30 3 Series, the E30 M3 has a power-assisted rack-and-pinion steering system, but the overall ratio has been reduced to 19.6:1.
What size brakes does the E30 M3 have?
All E30 M3s have vented front disc brakes measuring 11.1-inches (280mm) and solid rear discs measuring 11.1-inches (282mm). ABS is standard.
What are the factory wheel and tire sizes for the E30 M3?
There were two wheel and tire combinations available for the E30 M3. Early European-spec models and all North American-spec examples came with 205/55VR15 tires on 7x15-inch cross-spoke alloy wheels. Evolution models, along with the Cecotto/Ravaglia special editions and the later standard European-spec car, were equipped with 225/45ZR16 tires on 7.5x16-inch cross-spoke alloys.
Cosmetics
How is the M3’s exterior different from that of a normal E30 3 Series?
Because the E30 M3's shape had to be homologated for racing, all exterior body panels except the hood are unique to this model. The fenders are flared. The front and rear fascias contain unique 2.5-mph bumpers. The rear window is re-angled and the glass, both front and rear, is bonded. The trunk lid sits over 1.5-inches higher than the normal E30 3 Series, has a wing-type rear spoiler and is met by an extended cap over the C-pillar, all of which lower the Cd to 0.33 from 0.38. There is a roof-mounted radio antenna at the front. All window trim is of the blacked-out "Shadowline" variety. “M3” badges appear on the grille and decklid.
How does the exterior of the North American-spec E30 M3 differ from that of the Euro-spec model?
Cosmetically, the North American E30 M3 is nearly identical to the European-spec model. However, it can be easily identified by the black intake grilles near each front fog light in place of the European-spec model's body-color tow hook covers.There are also bumper-mounted side marker lights, slightly different headlight configurations and a high-mounted third brake light, all required by Federal law.
How is the interior of the E30 M3 different from that of a normal E30 3 Series?
The E30 M3 interior shares its basic architecture with the standard E30 3 Series. However, all M3s are equipped with manual sport seats in cloth, leather or a combination of the two. The rear seat is individually contoured for two passengers. A black headliner and a unique instrument cluster with red needles, an M logo and an oil temperature gauge under the tachometer in place of the economy-meter are also included. Cars without a driver-side airbag have a leather-wrapped M three-spoke steering wheel in one of two designs: The M-Technic I with a slimmer hub and the M tri-color stripe on the center spoke was used on M3s built before September, 1989. After this date, the M-Technic II steering wheel with a thicker rim and the M logo on the central spoke was used. The shift knob is also leather and includes an M stripe with the "dogleg" shift pattern (euro-spec) or the standard "H" configuration (North American models). It is always of the earlier, non-ergonomic design and comes attached to an integrated leather boot. The parking brake handle boot is also leather and is unique to the M3. All M3s were equipped with the check control vehicle monitoring system above the interior rearview mirror.
How does the interior of the North American-spec E30 M3 differ from that of the Euro-spec version?
Except for unique instrumentation and a generally higher level of equipment, the interior of the North American-spec E30 M3 is essentially identical to the Euro-spec model. Standard equipment on all North American-spec M3s included Bison leather sport seats, cruise control, air conditioning, power windows and sunroof, on-board computer II and an eight-speaker am/fm stereo cassette sound system. U.S.-spec models built for the 1990 and 1991 model years (9/89 thru 12/90 production) have a driver-side airbag with knee bolster.
How does the interior of the Canadian-spec M3 differ from that of the U.S. version?
Aside from small items like metric instrumentation, Canadian E30 M3s are essentially identical to the U.S. versions, with a few minor exceptions: Heated seats are standard on all model years (these did not appear until the 1990 model year on U.S.-spec cars, and then only as an option) and cars built for the 1990 and 1991 model years do not have a driver’s side airbag or knee bolster.
What features were optional on the E30 M3?
The European-spec versions of the E30 M3 were far less lavishly equipped than the North American-spec version. Optional equipment, depending on the market and production date, included: metallic paint, headlight washer/wipers, leather upholstery, heated seats, power windows, power sunroof, rear headrests, on-board computer II, air conditioning, Electronic Damper Control (EDC) and various audio systems.
North American-spec cars were fitted with most of the above items as standard, and thus options were limited to metallic paint, heated seats (from 9/89 production on U.S. models, always standard in Canada) and a glass moonroof (1990-91 models only). A CD changer could be added as a factory option starting with 9/88 production.
Special Versions
Were there any special editions of the E30 M3?
There were seven special editions of the E30 M3. Three were homologation specials known as the Evoultion I, Evolution II and Sport Evolution. The remaining four were based more closely on regular production models, but had special cosmetic features. These editions were called the Tour de Corse, Europa Meister 88, Johnny Cecotto and Roberto Ravaglia.
What distinguishes an E30 M3 Evolution I?
The initial E30 M3 Evolution was created to homologate refinements to the E30 M3 designed to make it more competitive in its competition guise. The main mechanical alteration was a revised cylinder head, distinguishable by an "E" cast into it, though peak power remained unchanged from the standard non-catalyst M3 at 200 hp (DIN). The model is otherwise identical to a standard European-spec E30 M3 and lacks a numbered dash plaque or any other identifying feature to denote this special series. It is thought that 505 examples were produced in the Spring of 1987.
What distinguishes an E30 M3 Evolution II?
The E30 M3 Evolution was followed by the E30 M3 Evolution II, all of which were built in the Spring of 1988. Unlike the first Evolution, the E30 M3 Evolution II has significant mechanical upgrades over the regular M3. New pistons raised the compression to 11:1 (from 10.5:1), the air intake was improved, the flywheel lightened and the engine management revised. Power increased to 220 hp, torque to 181 lb/ft, both at the same rpm as the standard E30 M3. These engines have cam covers painted in white with the tri-color Motorsport emblem.The close-ratio gearbox carried over unchanged, though the final drive was reduced slightly from 3.25:1 to 3.15:1.
There were no alterations to the chassis or brakes, though the larger 7.5x16-inch wheels with 225/45ZR16 tires (as fitted to the Evolution I) were standard, along with the deeper front airdam, additional rear spoiler and front brake cooling ducts in place of foglights from the Evolution I. In addition, thinner glass plus a lightened trunk lid and bumpers reduced weight by 22 pounds.
The E30 M3 Evolution II was available in only three exclusive exterior colors: Misano Red (236), Macao Blue metallic (250) and Nogaro Silver metallic (243). The sole interior choice was Silver cloth with matching leather bolsters. Both the front and rear seats were fitted with the tri-color M lapels (as used on the E28 M535i/M5), plus the the special M dead pedal and door sill plates with the "M3" insiginia from the first M3 Evolution model. Finally, a center console-mounted plaque denoting the specific number of each example out of 500 was fitted to every Evolution II.
What distinguishes an E30 M3 Sport Evolution?
The E30 M3 Sport Evolution, produced in late 1989 and early 1990, was the most extensively modified of the three E30 M3 Evolution editions. The cylinder bore was increased to 95mm (from 84mm) and a long-stroke crank was added to boost displacement to 2,467cc (from 2,305). In addition, the valves were enlarged and a more aggressive cam was fitted. Special nozzles sprayed oil under the pistons to keep them cool. All Sport Evolution motors were equipped with catalysts. The end result was a power increase to 238 hp at 7,000 rpm, though peak torque decreased slightly (over the Evolution II) to 177 lb/ft at 4,750 rpm. These engines use the regular black cam cover but have red spark plug wires. The gearbox remained unchanged but the 3.15:1 final drive was fitted.
Like the Evolution II, the Sport Evolution has thinner glass, a lighter trunk and bumpers, and brake cooling ducts in place of foglights. In addition, it also has a smaller fuel tank. For homologation purposes, the Sport Evolution has unique front and rear spoilers with adjustable extensions for greater downforce, even wider front fenders, and reprofiled grille slats with sealed gaps for better aerodynamics, all of which have negligible effect on the street. The M3 Sport Evolution also sits 10mm lower than the normal E30 M3.
The Sport Evolution was only offered only in Jet Black (668) with red bumper stripes or Brilliant Red (308) with black bumper stripes. The wheels are the same 7.5x16-inch cross-spoke items used on other Evolution models, but the spokes are painted a darker Nogaro Silver. Comfort items such as power windows, a sunroof, on-board computer and air conditioning were all deleted in order to keep weight down, though they could be ordered as options. Even the interior map lights and grab handles were deleted. Recaro sport seats with integrated headrests were standard in Anthracite M cloth. Black leather with the M tri-color logo was an option. A suede-covered M Technic II steering wheel, shift knob and parking brake handle were included along with red seatbelts. Door sill plates with color "M3" insignias were added and a special plaque denoting each car as a Sport Evolution appears on the center console (though it does not include the unique number of each example out of the 600).
What distinguishes an E30 M3 Tour de Corse?
Though not considered an "official" model by BMW AG, the E30 M3 Tour de Corse was a special edition of the M3 Evolution I created by BMW France exclusively for the French market to celebrate the win of French drivers Bernard Beguin and Jean-Jacques Lenne in the Tour de Corse rally. The Tour de Corse model shares the "E-stamped" cylinder head, 7.5x16-inch cross-spoke alloy wheels, M dead pedal and special door sill plates featuring the "M3" logo with the Evolution I. However, unlike the Evolution I, the Tour de Corse does not feature the extended front airdam, additional rear lip spoiler or brake cooling ducts in place of fog lights. Instead, it is cosmetically identical to the standard E30 M3 aside from two "Tour de Corse" badges, one in place of the standard M3 badge on the grille and another on the left side of the trunk lid.
Inside, the Tour de Corse includes tri-color M stripe lapels on the front and rear seats and a numbered plaque on the center console bearing the signatures of Bernard Beguin and Jean-Jacques Lenne. It is thought that 200 examples of the E30 M3 Tour de Corse were produced within the series of 505 cars that make up the entire Evolution I production. All were Diamond Black metallic (181) with a Black leather interior and equipped with the power sunroof, on-board computer II, interior headlight adjustment and headlight washer/wipers.
What distinguishes an E30 M3 Europameister?
BMW decided to celebrate the dominance of the E30 M3 in the 1988 Touring Car season with a limited run of 148 "Europameister" edition road cars built in October and November of that year. These were based on the regular production M3 with the 195-hp catalyst-equipped engine. All were painted Macao Blue metallic (250) with a Silver extended Nappa leather interior including the center console and special diagonally-pleated door panels. In addition, the Europameister was given the larger 7.5x16-inch alloy wheels and special door sill plates with the "M3" insignia. A special plaque on the center console reads "Europameister 1988 auf BMW M3" and is signed by driver Roberto Ravaglia.
What distinguishes an E30 M3 Cecotto?
In order to celebrate the many competition victories of factory driver Johnny Cecotto, BMW produced a speical version of the E30 M3 during 1989 that was named in his honor. This model introduced the 215-hp version of the 2.3-liter S14, still rated at 170 lb/ft of torque, though now at a slightly lower 4,600rpm. This engine, which would become standardized on European-spec M3s beginiing in September of 1989, can be identified on the Cecotto by its body-color cam cover.
All M3 Cecottos are painted Misano Red (236), Macao Blue metallic (250) or Nogaro Silver metallic (243) and carry the Evolution II front and rear spoilers. They are further distinguished by their 7.5x16-inch wheels with special black centers. However, unlike the Evolution models, they do not include the thinner glass or front brake ducts in place of foglights.
On the inside, the Cecotto has the standard M3 sport seats, though these are generally trimmed in a special Anthracite or Silver M-Technic cloth with leather bolsters (also offered as a rare option on regular ECE E30 M3 models starting in 9/89). As an alternative, extended Black Bison leather, Black Nappa leather or Silver Nappa leather could be specified at extra cost. Cecotto editions were also equipeed with the on-board computer II and internal headlight adjustment. Additional special features included door sill plates with a color "M3" insignia, a green-tinted windshield band, an illuminated shift knob and a plaque on the center console that displays the signature of Johnny Cecotto, as well as the exclusive number of each car out of 505. (In fact, only 480 Cecottos were built, the other 25 being nearly identical Ravaglia editions see below).
Finally, it is believed that the Swiss market received a special series of 50 additional E30 M3 Cecotto models in late 1989 and early 1990. These are identical in every way to the normal Cecotto edition model aside from being fitted with a special 211-hp (DIN) version of the S14 motor, the later M-Technic II steering wheel and a unique center console plaque that bears the signature of Johnny Cecotto but is not individually numbered. The Swiss Cecotto models do not contain a unique VIN sequence, but are instead included within the standard E30 M3 range.
What distinguishes an E30 M3 Ravaglia?
Instead of the E30 M3 Johnny Cecotto edition, the U.K. received only the E30 M3 Roberto Ravaglia edition, which was essentially an identical car except for the signature of another BMW factory race driver on the numbered plaque. Only 25 were built.

E30 M3 convertible
Production Versions:
BB01: Euro-spec (200 hp), 06/88-09/88 and 04/89-06/89
BB05: Euro-spec with catalyst (195 hp), 07/88 to 09/88 and 03/89-06/89
BB05: Euro-spec with catalyst (215 hp), 03/90-06/91
History
What makes the E30 M3 convertible unique?
The E30 M3 convertible combines the drivetrain, chassis and much of the bodywork from the E30 M3 sedan with the open-top body style of the E30 3 Seres convertible.
Where was the E30 M3 convertible first introduced?
A six-cylinder E30 3 Series convertible prototype with M3 bodywork and all-wheel-drive was displayed at the 1985 Frankfurt motor show. The production version, with the four-cylinder S14 engine and rear-wheel drive chassis, did not appear until the middle of 1988.
Where was the E30 M3 convertible built?
Because of its low production volume, the E30 M3 convertible was assembled by hand at BMW M's Garching facility, much like the E28 and E34 M5s. Bodies were supplied from the normal E30 assembly lines, then fitted at Garching with the special drivetrain, chassis and interior.
Production Data
How many versions of the E30 M3 convertible were there?
There were three versions of the E30 M3 convertible, all in left-hand drive and all built to European specification. Cars produced in 1988 and 1989 use the standard 2.3-liter S14 engine in either non-catalyst (200 hp) or catalyst (195 hp) form. After nearly a year out of production, a second batch of catalyst-equipped cars was assembled starting in March, 1990. These have the later 215-hp version of the S14 engine.
How many of each version were built?
ECE (non-cat): 136 built from 06/88 thru 09/88 + from 04/89 thru 06/89
ECE (cat/195 hp): 174 built from 07/88 thru 09/88 + from 03/89 thru 06/89
ECE (cat/215 hp): 476 built from 03/90 thru 06/91
Drivetrain
How is the E30 M3 convertible mechanically different from the hardtop version?
Aside from the structural reinforcements fitted to all E30 convertibles, the E30 M3 convertible is mechanically identical to the hardtop.
Chassis
How is the E30 M3's chassis different from that of the closed version?
The E30 M3 convertible uses slightly different springs and shocks to compensate for the car's added weight (increased by almost 400 pounds over the coupe). The suspension, steering, brakes, wheels and tires are otherwise identical to those of the E30 M3 coupe.
Cosmetics
How is the E30 M3 convertible cosmetically different from that of the sedan?
The E30 M3 convertible shares most of the coupe’s body panels, save for the trunk lid, which is a stock E30 convertible item and is not equipped with a rear spoiler. The convertible top is also identical to the one fitted to the regular E30 models and is power-operated as standard.
How is the E30 M3 convertible's interior different from that of the sedan?
Like the closed car, the E30 M3 convertible's interior features sport seats, an M steering wheel (in one of two versions) and the M instrument cluster. The convertibles were also fitted with the "M3" door sill plates used on the M3 Evolution models. Cars equipped with optional leather upholstery have the M tri-color stripes on both front and rear seats, as well as unique door panels with diagonal pleating.
What items were optional on the E30 M3 convertible?
The E30 M3 convertible was generally equipped with more standard features than the closed car. All were fitted with power windows and a power-operated folding soft top. The standard E30 M3 options were all available, as was a removable hardtop with rear window defroster and an extended leather interior including leather on the center console, door panels and door pulls. A number of special-order features not found on the usual option list (phone, fax, suede interior trim, leather dashboard, etc.) could also be requested due to the model's hand-built assembly.
Special Versions
Were there any special versions of the E30 M3 convertible?
There were no official special editions of the E30 M3 convertible, but it is thought that at least one example was built with the 220-hp engine from the E30 M3 Evolution II. It is not known if this car also featured the Evo II's cosmetic items.

What makes the 850CSi unique?
The 850CSi is the the BMW Motorsport-developed version of the E31 8 Series coupe. It is powered by the S70 V12 engine, a BMW Motorsport-enhanced version the standard production M70 powerplant. In addition, the 850CSi features a BMW Motorsport-tuned chassis and several unique cosmetic items.
Where was the 850CSi introduced?
The 850CSi was introduced at the 1991 Frankfurt International Motor Show.
Where was the 850CSi produced?
The 850CSi was built on the regular 8 Series assembly line at BMW's Dingolfing factory.
Is the 850CSi considered an M car?
Although not badged as such, the 850CSi was developed by BMW Motorsport (later renamed BMW M) and is therefore a true M car.
If the 850CSi was developed by M, why is it not badged as an "M8"?
BMW Motorsport did develop a prototype 8 Series with a lightweight body and a 550-hp 48-valve V12 engine that was known as the M8. However, BMW pulled the plug on the M8 and stated, "We're just not interested in putting our name on cars like this anymore." Instead, a more mild 8 Series with a 24-valve version of the V12 and normal steel body panels was chosen for production. This model was named 850CSi, perhaps because it was more closely related to the regular 850Ci coupe than the M8 prototype or perhaps because BMW did not wish to attach the M badge to a rather large and heavy grand touring coupe.
What does the "CSi" suffix denote?
The "CSi" suffix was first used in 1971 on the E9 3.0 CSi coupe to denote "Coupe Sport injection". It was carried over by the 3.0 CSi's successor, the E24 633CSi (and its successors, the 628CSi, 635CSi and M635CSi). However, in the case of the 8 Series, the CSi suffix is unique to the M-powered version (all other 8 Series models have either an "i" or "Ci" suffix).
Production Data
How many versions of the 850CSi were developed?
Three versions of the 850CSi were developed: Two European-spec models (left-hand drive and right-hand drive) and a United States-spec version.
How many of each version were produced?
ECE (LHD): 1,125 built from 08/92 thru11/96
ECE (RHD): 160 built from 06/93 thru 10/96
US (LHD): 225 built from 10/93 thru 06/95
What changed during the production of the 850CSi?
There were no major mechanical changes to the 850CSi during the three and a half years that it was produced. However, the 850CSi did receive a myriad of smaller running changes that affected all 8 Series models. These included the addition of Coded Driveaway Protection (1/95 producton) and revisions to the ABS braking system, door locking system, audio system, on-board computer and other minor equipment changes.
How does the the U.S.-spec version of the 850CSi differ from the European-spec model?
Though lagely similar in specification and appearance, the U.S.-spec 850CSi was denied the following items, largely for cost reasons:
-Engine oil cooler
-Transmission oil cooler
-Active Rear-Axle Kinematics (AHK)
-Upgraded 13.6-inch front brakes rotors, all rotors with "floating" design
-Smoked front turn signal lenses
-M aerodynamic rear-view mirrors
However, U.S. models do include exterior door handles embossed with "BMW Motorsport" and Extended Yew wood interior trim, both items not normally found on the European-spec version.
Drivetrain
How is the S70 engine different from the M70 V12 upon which it is based?
When creating the 850CSi's S70 V12 motor, BMW Motorsport began with the standard 24-valve SOHC M70 engine and instituted the following changes:
-Increased bore (from 85mm to 86mm) and stroke (from 79mm to 80mm) for a new total displacement of 5,576cc (from 4,988cc)
-Lighter pistons
-Increased compression (from 8.8:1 to 9.8:1)
-More aggressive valve timing for increased high-rpm power
-Larger diameter exhaust pipes
-Variable rpm limit (6,400 in 1st+2nd, 6,200 in 3rd, 6,100 in 4th. 6,000 in 5th+6th)
-Adjustable throttle sensitivity via dual mode (Sport or Komfort) console-mounted switch
-Engine oil cooler (European-spec models only)
These modifications resulted in an increase in maximum power from 300 hp (DIN) or 296 hp (SAE) at 5,200 rpm to 380 hp (DIN) or 372 hp (SAE) at 5,300 rpm. In addition, maximum torque was increased from 332 lb/ft at 4,100 rpm to 402 lb/ft at 4,000 rpm.
This engine can be identified by the "Powered by M" inscription on the central cam cover between the two banks of cylinders.
What kind of gearbox does the 850CSi have?
The sole gearbox offered for the 850CSi was the Getrag Type E six-speed manual with the following ratios: 4.25 (1), 2.53 (2), 1.68 (3), 1.24 (4), 1.00 (5), 0.83 (6). This is mated to a 2.93:1 rear end with limited slip differential. In addition, Automatic Stability Control plus Traction (ASC+T), which can apply the brakes and/or reduce engine power in the event of traction loss, is fitted as standard to the 850CSi. Finally, European-spec models are equipped with a transmission oil cooler.
Chassis
How is the chassis different from that of a standard 8 Series coupe?
The 850CSi's chassis is based on that of a normal 8 Series and thus is made up of MacPherson struts in front and a multi-link system that comprises five components (upper transverse link, two lower transverse links, longitudinal link and integral link) in the rear. However, BMW Motorsport specified stronger front hubs, stiffer shocks and shorter springs (by 10mm) for the 850CSi.
In addition, all Euro-spec cars are fitted with Active Rear-Axle Kinematics (known by its German abbreviation AHK for Aktive Hinterachs-Kinematik). The system works by turning the rear wheels in the same direction as the fronts in order to facilitate change of direction and weight shift in a corner. The hydraulically-controlled AHK system activates at speeds above approximately 60 kph (37 mph) and can turn the rear wheels up to 2.5 degrees depending on the angle of the front wheels.
How is the steering different from that of a standard 8 Series coupe?
The 850CSi's steering system is based on the same recirculating ball design as the standard 8 Series but incorporates ZF Servotronic vehicle-speed-sensitive power assist (in place of the usual engine-speed-sensitive system) and a quicker rack (2.8 turns lock-to-lock instead of 3.3 turns).
What size brakes does the 850CSi have?
There are two different braking systems for the 850CSi. European-spec cars are equipped with the same braking system that was fitted to the E34 M5 starting with May, 1994 production. This consists of 13.6-inch vented discs incorporating "floating" rotors and four-piston calipers in the front and 12.8-inch vented discs in the rear. U.S.-spec cars are fitted with the same brakes as the standard five-liter 850i/850Ci: 12.8-inch vented discs in the front and 12.8-inch solid discs in the rear.
What size wheels and tires does the 850CSi have?
There were two different wheel and tire packages for the 850CSi. Until early 1995 production, the 850CSi was equipped exclusively with three-piece M System II wheels consisting of a five-spoke forged alloy center and an outer cover in a "throwing star" design. These are sized 8x17-inch in the front and 9x17-inch in the rear with 235/45ZR17 and 265/40ZR17 tires, respectively.
As of early 1995 production, 18-inch M Parallel Spoke forged alloy wheels became available, either as an option or as standard equipment depending on the market. The 8x18-inch front wheels are fitted with 245/40ZR18 tires, while the 9.5x18-inch rear wheels carry 285/35ZR18 tires.
Cosmetics
How dos the exterior of the 850CSi differ cosmetically from that of other 8 Series?
Aside from its M-designed 17- or 18-inch wheels, the exterior of the 850CSi is distinguished by a unique front fascia that includes a deeper front airdam and air intake, more pronounced side sills and four round exhaust tips, two pairs on either side of a "diffuser" panel under the bumper. European-spec models also feature aerodynamic M rear-view mirrors, while U.S.-spec cars have unique door handles that are embossed with "BMW Motorsport" script. An "850CSi" badge appears on the trunk lid, but there are no M badges on the exterior of the car.
How is the interior of the 850CSI different from that of a normal 8 Series?
The interior of the 850CSi shares its basic architecture and design with all 8 Series coupes. The power and heated front seats are identical in shape and function to those fitted to other 8 Series models and include a three-position memory on the driver-side seat. Unlike other 8 Series models, however, the interior of the 850CSi could also be ordered in several two-tone or "Bicolor" Nappa leather combinations (Black/Dark Silvergray, Light Silvergray/Dark Silvergray, Black/Lotus White) in addition to all Black.
Three different airbag-equipped steering wheels were offered depending on the market and production date: a three-spoke design, a four-spoke design (through 8/93 production) and a four-spoke M design with tri-color stitching on the rim (from 9/93 production). A leather shift knob was fitted to every 850CSi while all U.S.-spec models and some later European-spec cars received the leather shift knob with M tri-color stripe.
Every 850CSi also features a special instrument cluster with red needles, a 300 kph/180 mph speedometer and a unique tachometer with a graduated redline (to reflect the variable rev limiter). There are also special plates with the "M" logo on both door sills. The U.S.-spec 850CSi is further distinguished by its standard Yew wood trim on the dashboard, front and rear center consoles, door panels and rear side panels. Several other types of wood trim could be ordered as an option in other markets.
What features were optional on the 850CSi?
The 850CSi was the flagship of the BMW range and was therefore fitted with most features as standard equipment. Options varied from market to market on Euro-spec cars but generally included various audio and phone systems, a power rear window sunshade, retractable headlight washers, wood trim and (from early 1995) 18-inch M Parallel Spoke wheels. There were no factory options for the U.S.-spec model.
Special Versions
Were there any special versions of the 850CSi?
There were no official factory special editions of the 850CSi. However, the 850CSi could be ordered in certain markets outside of North America with the rare "Color-Line" option consisting of monochromatic paint and interior trim in one of three color schemes (Calypso Red, Tobago Blue or Barbados Green).
In addition, customers often requested paint, interior trim and/or special equipment from BMW Individual, the branch of BMW M responsible for tailoring vehicles to specific customer requests. Thus, it is fairly common to find examples with items not usually found on the normal equipment list. One extreme example is a special 850CSi built for the painter David Hockney (probably as a gift for having painted the 850CSi Art Car) with an integrated water bowl for his dog between the rear seats.

What makes the E34 M5 unique?
The E34 M5 is the BMW Motorsport-developed version of the E34 5 Series. It is powered by the S38 twin-cam 24-valve inline-six, an evolution of the engine used in the E28 M5 and E24 M6. It also has a BMW Motorsport-tuned chassis and a few special cosmetic pieces.
When was the E34 M5 first introduced?
The original E34 M5 was introduced in September, 1988. The later 3.8-liter version first appeared at the 1991 Frankfurt motor show, as did the E34 M5 Touring.
Where was the E34 M5 produced?
Unlike the normal 5 Series, M5s were hand-assembled at the BMW Motorsport facility in Garching, a suburb of Munich. Bodies were pressed at the normal Dingolfing factory, then sent to Garching where they were mated with the engine and interior trim. The only exception was the South African-spec model, assembled at BMW's Rosslyn, South Africa factory from German-supplied Complete Knock Down (CKD) kits.
Production Data
How many versions of the E34 M5 were produced?
The E34 M5 was produced in two distinct versions, each with several variations. Early cars have a 3.6-liter (actually 3,535cc) version of the 24-valve S38 inline-6 known as the S38 B36. These were built in both left-hand and right-hand drive configurations, as well as a North American-specification edition. There were also a small amount of 3.6-liter M5s assembled in South Africa, exclusively for that market.
Starting in late 1991 (with the exception of North American-spec cars and those assembled in South Africa), the M5 switched to a 3.8-liter (3,795cc) version of the S38 (designated S38 B38) and gained Adaptive M Suspension, plus a few cosmetic changes. The 3.8-liter M5s were available in both LHD and RHD variations, but there were no North American or South African editions. However, there was a small production run (891 built) of the E34 M5 Touring, or station wagon, all built to 3.8-liter European specification in left-hand drive.
How many of each version were built?
ECE 3.6 (LHD): 5,877 built from 9/88 thru 4/92
ECE 3.6 (RHD): 524 built from 11/89 thru 11/91
NA 3.6 (LHD): 1,678 built from 12/89 thru 4/93
SA 3.6 (RHD): 265 built from CKD kits 9/90 thru 3/93*
ECE 3.8 (LHD): 2,676 built from 12/91 thru 7/95
ECE 3.8 Touring (LHD): 891 built from 3/92 thru 8/95
ECE 3.8 (RHD): 343 built from 12/91 thru 6/95
*Figures indicate final completion date of vehicles assmebled in Rosslyn, South Africa.
What major revisions were made to the European-spec E34 M5 during its production?
Except for minor trim and equipment variations, there were few revisions to the original European-spec E34 M5 during its production. The first major round of changes occurred with the introduction of the more powerful 3.8-liter M5 in late 1991. Along with the larger engine, the 3.8-liter M5 brought Adaptive M Suspension, a reduced-effort clutch and a myriad of cosmetic alterations. Also, the M5 Touring was added at this time.
The final evolution of the E34 M5 entered production in May of 1994 and included the following upgrades:
-Getrag Type D six-speed manual gearbox
-Enlarged brake rotors with two-piece "floating" front calipers
-Nurburgring Package standardized with Servotronic steering as an option
-18-inch M Parallel Spoke wheels
-Widened front "kidney" grilles with revised hood to match
How many examples of the North American E34 M5 were produced for each model year?
Of the 1,678 examples of the E34 M5 produced for North America (USA and Canada), the following are the production totals for each of the three model years:
1991: 1,280*
1992: 125
1993: 273
*NOTE: Though technically 1991 models, E34 M5s built for North America before 9/90 were actually built to 1990 specification. These comprise 495 of the 1,280 1991 models produced.
What changed during the production of North American-spec M5s?
Though the E34 M5 was introduced in North America as a 1991 model, production actually began in December of 1989. Cars produced before September of 1990 were therefore built to 1990 specification. Thus. the North American-spec E34 M5 did not actually adopt true 1991 specifications until approximately nine months after production began. At that time, the following items were modified:
-Rear center console deleted (became optional in Canada)
-Ellipsoid headlights and foglights replaced by "free form" versions
-Radio head unit updated to the later version (as used in other 1991 E34 models)
-Automatic climate control deleted (only used in some early 1991 E34 M5 examples)
-Tilt steering wheel added
-Light Silvergray leather upholstery offered in place of Silvergrey
For the 1992 model year (starting 7/91 production) the following changes were introduced:
-Rear axle ratio changed from 3.91:1 to 3.73:1 for better fuel economy
-Remote locking included as standard equipment
-ZF Servotronic (vehicle-speed sensitive) power steering in place of engine-speed sensitive version (USA models only)
-Reduced clutch pedal effort
-Door sill plates updated to the later design (from 01/92 production)
-Calypso Red metallic (252) paint available
For the final 1993 model year (starting 9/92 production), the North American M5 was given some cosmetic updates, many of which were first introduced on the Euro-spec 3.8-liter model:
-M System II ("throwing star") wheel covers replace M System I ("turbine")
-M-Technic side rear-view mirrors in place of the standard 5 Series versions
-Shadowline exterior trim in place of chrome
-Front exterior door handles embossed with "BMW Motorsport" text
-Birds-eye maple wood trim added in either a gray or black stain (not available in conjunction with the extended leather interior option on Canadian models)
-M tri-color stitching added to the airbag steering wheel rim
-Brilliant Red (308) paint replaced by Mugello Red (274)
-Lagoon Green metallic (266) and Avus Blue metallic (276) paints available (Lagoon Green for USA only)
How does the U.S.-spec E34 M5 differ from the Canadian version?
In addition to items mandated by different government regulations such as imperial versus metric instrumentation, the U.S and Canadian E34 M5s differ in the following ways:
U.S Specification:
Headlight washers: Not offered
Leather trim: Nappa leather on seats only
Fixed rear console: Standard before 09/90 production, then deleted
Heated front seats: Optional
Driver-side airbag with knee bolster: Standard
Three-position driver seat memory: Optional on 1992 models only
Power steering column adjustment: Optional on 1992 models only
Servotronic power steering: Standard on 1992 and 1993 models
Canadian Specification:
Headlight washers: Standard
Leather trim: Nappa leather on seats only, optional Extended trim with Nappa leather on center console, door pulls, glovebox door
Fixed rear console: Standard before 09/90 production, then optional
Heated front seats: Standard
Driver-side airbag with knee bolster: Optional
Three-position driver seat memory: Optional
Power steering column adjustment: Optional
Servotronic power steering: Not offered
Drivetrain
How is the S38 engine in the E34 M5 different from the version used in the E28 M5?
The early E34 M5 uses an evolution of the 24-valve inline-six found in the E28 M5 and E24 M635CSi/M6. Designated S38 B36, the engine technically remains a 3.5-liter, with a bore of 93.4mm (same as the previous engine) and a stroke of 86mm (up 2mm on the early S38) for a total capacity of 3535cc (up from 3453cc). The added stroke is due to a new forged steel crankshaft, though the camshafts were also changed. Compression is up slightly (10:1 versus 9.8:1). Further enhancements include:
-An electronically-controlled butterfly valve in the inlet manifold to provide better low-rpm and mid-range power
-Bosch Motronic fuel injection for precise metering of the air/fuel mixture
-Improved flywheel
-Equal length stainless steel headers
-Three way ceramic catalysts (similar to those used on the M70 V12 engine)
The S38 B36 is rated at 315 hp (DIN) or 310 hp (SAE) at 6,900 rpm and 266 lb/ft of torque at 4,750 rpm. Like the earlier S38 B35, it carries the "BMW M Power" inscription on its cam cover but the design of almost every component is different.
Unlike the engine used in the E28 M5, the S38 B36 engine in the E34 M5 was designed to meet all worldwide emission standards from the start. Therefore, the engines used in North American- and South African-spec E34 M5s are essentially the same as those used in the European-spec models.
How is the 3.8-liter M5 engine (S38 B38) different from the 3.6-liter version (S38 B36)?
The final evolution of the S38 powerplant, the S38 B38, was used in later versions of the E34 M5, none of which were sold in North America. In this application, the bore was increased (to 94.6mm) and the stroke lengthened (to 90mm), raising the displacement to 3,795cc. Though the added capacity makes the S38 B38 the largest six-cylinder production BMW engine of the modern era, it represents only a portion of the major revisions developed by BMW Motorsport at this time. Others include:
-Larger intake and exhaust valves
-Lighter pistons
-Shorter conrods
-Increased compression to 10.5:1
-Bosch Motronic 3.3 engine management system
-Distributorless ignition with six coils
-Redesigned intake and exhaust manifolds
-Revised throttle butterfly linked to Motronic engine control
-Dual-mass flywheel with harmonic balancer
-Metal catalysts for reduced backpressure and better heat conduction
The S38 B38 is normally rated at 340 hp (ECE)/347 hp (DIN) at 6,900 rpm and 295 lb/ft of torque at 4,750 rpm. However, a cleaner version was developed for Austria and Switzerland, rated at 334 hp (ECE) and later 327 hp (ECE). The S38 B38 can be identified by its grey (instead of black) cam cover surround.
What kind of gearbox does the E34 M5 have?
All M5s built before May, 1994 have a Getrag 280/5 five-speed manual gearbox with the following ratios: 3.51 (1), 2.08 (2), 1.35 (3), 1.00 (4), 0.81 (5). These cars have a 3.91:1 final drive, with the exception of North American-spec E34 M5s built to 1992 and 1993 specification which have a taller 3.73:1 final drive for better fuel economy.
As of May, 1994 production, the five-speed was replaced with a Getrag Type D six-speed manual box with the following ratios: 4.23 (1), 2.52 (2), 1.66 (3), 1.22 (4), 1.00 (5), 0.83 (6). A taller 3.23:1 final drive was fitted at this time.
All E34 M5s have a standard limited slip differential with a maximum locking of 25 percent.
Chassis
How is the E34 M5's suspension different from the standard E34 5 Series?
The E34 M5’s chassis is based on the MacPherson strut/semi-trailing arm design of the normal E34 5 Series but incorporates the following changes from BMW Motorsport:
-20mm reduction in ride height
-25 percent firmer spring rates
-Firmer shock valving all around and self-leveling in the rear
-Thicker antiroll bars (25mm vs. 23mm in the front, 18mm vs. 15mm in the rear)
-Adjustable rear toe-in
All 3.8-liter M5s are further fitted with the Adaptive M Suspension, an M-tuned version of the Electronic Damping Control system that was introduced in the E32 7 Series. This system electronically chooses the optimum shock rates based on sensors that gather road speed, steering input, acceleration/deceleration loads and lateral body movements. Furthermore, M5s equipped with the Nurburgring package (standard from May, 1994) have a control switch on the dashboard to lock the Adaptive M Suspension into the firmest setting during aggressive driving.
How is the E34 M5's steering system different from the standard E34 5 Series?
Like all E34 5 Series, the E34 M5 uses a recirculating ball steering design, but the overall ratio is reduced from 16.2:1 to 15.6:1.
Two types of power assistance were offered: An engine-speed sensitive system was fitted to all European-spec 3.6-liter M5s and on North American models built before September, 1991. A vehicle-speed sensitive system developed by ZF and called Servotronic was available on European-spec 3.8-liter models as either a stand-alone option or as part of the optional Nurburgring Package. However, Servotronic was not included with the Nurburgring Package after it became standard equipment in May of 1994, but continued to be available as an individual option. Servotronic was also fitted as standard to all North American-spec M5s built after September, 1991 (i.e. 1992 and 1993 model years).
What is the Nurburgring Package?
In addition to the standard Adaptive M Suspension fitted to all 3.8-liter M5s, the Nurburgring Package could be added as an extra cost option. This consisted of ZF Servotronic (vehicle-speed sensitive) power steering, a 19mm rear anti-roll bar, wider 255/40ZR17 rear tires on 9x17-inch alloy wheels (already standard on the Touring) and a control switch for the adjustable shocks that allowed them to be locked in the firmest position. This package became standard on all M5s as of May, 1994 production, with the exception of the Servotronic steering which became a separate option at this time.
What size brakes does the E34 M5 have?
All M5s built before May, 1994 have upgraded vented front disc brakes measuring 12.4-inches. The rear rotors measure 11.8-inches in diameter and are vented as of 10/89 production. The May, 1994 update brought even larger front and rear brakes (now 13.6-inches and 12.8-inches, respectively) and the front rotors were changed to a two-piece “floating” design for better heat dissipation.
What are the factory wheel and tire sizes for the E34 M5?
There are two factory 17-inch wheels for the E34 M5, M System I and M System II. Both are a two-piece wheel with a forged five-spoke center and a cast rim covered by an outer cover. The only difference is the design of the outer cover, "turbine" for the M System I and "throwing star" for the M System II. This outer cover is interchangeable between the two M System wheels, making updating form the earlier style to the later style an easy (and therefore common) procedure.
The 3.6-liter M5 is equipped with 235/45ZR17 tires on 8x17-inch M System I wheels. However, for the 1993 model year, North American-spec M5s use the M System II design in the same size. In addition, wider 255/40ZR17 rear tires on 9x17-inch M System I wheels were available as an option in some markets (not North America).
All 3.8-liter M5 sedans built before May, 1994 are equipped with 235/45ZR17 tires on 8x17-inch M System II wheels. Sedans equipped with the optional Nurburgring Package and all Tourings use wider 255/40ZR17 rear tires on 9x17-inch M System II wheels.
All M5s built after May, 1994 have 245/45ZR18 tires on all four corners with staggered M Parallel Spoke wheels measuring 8x18-inches in the front and 9x18-inches in the rear. Note: Though nearly identical in style to the 18-inch M Parallel Spoke wheels later used on the E38 7 Series, the E34 M5 wheels have a matte silver finish and a unique offset.
Cosmetics
How is the E34 M5’s exterior different from that of a normal 5 Series?
An E34 M5 is most easily distinguished from a normal 5 Series by its unique lower body panels that include a front airdam, side valances and rear diffuser. These are painted in a contrasting Diamond Black metallic (181), Sebring Grey metallic (229) or Granite Silver metallic (237), depending on the car’s exterior color and production date. In addition, the E34 M5 has large-diameter twin exhaust pipes and “M5” grille and decklid badges (only the former on M5s built after May, 1994). Like the previous E28 M5, these could be deleted upon request. Dechromed window trim (known as Shadowline) was optional on the E34 M5 in most markets, as was a body-color rear decklid spoiler. Starting with the production of the 3.8-liter model, the E34 M5 could be ordered (in most markets) with aerodynamic M rear-view mirrors (also fitted to all North American-spec E34 M5s for the 1993 model year). All E34 M5 sedans have a black plastic panel that fills in the gap between the taillights and the license plate. Though this panel was only fitted to M5 sedans, this same area on the M5 Touring is covered in an exclusive textured black paint (instead of the normal body-color).
The E34 M5 was also the only regular production 5 Series to be fitted from the factory with 17-inch M alloy wheels in either a “turbine” style known as M System I (all 3.6-liter models and North American-spec cars up to 9/92) or a “throwing star” design known as M System II (all 3.8-liter cars up to 5/94 and North American-spec after 9/92). The final six-speed 3.8-liter M5s (from 5/94) use an 18-inch M Parallel Spoke design, also essentially unique to the M5 within the E34 range.
How is the North American-spec E34 M5 cosmetically different from the European-spec version?
Aside from government-mandated safety features such as bumper-mounted side marker lights, North American cars are visually very similar to their Euro-market counterparts. The sole exception are 1993 models (built from 09/92-03/93). These have the exterior appearance of the European-spec 3.8-liter M5, but retain the 3.6-liter engine and chassis.
How is the South African version of the E34 M5 cosmetically different from the German-built version?
The South African-built M5s are cosmetically identical to the European-spec cars. However, like the South African-spec E28 M5s, their bodies were painted at BMW's Rosslyn factory, thus exterior paint choices may have been limited.
How is the exterior of the 3.8-liter M5 cosmetically different from that of the 3.6-liter model?
The wheels are the main exterior differentiator between a 3.6-liter E34 M5 and a later 3.8-liter model. The European-spec 3.6-liter M5s were all equipped with the M System I (“turbine”) wheel design, while the 3.8 utilized the M system II (“throwing star”) version until April, 1994. At that point, all M5s were upgraded to the 18-inch M Parallel Spoke wheels. (Note: North American-spec 1993 M5s use the later M System II wheel even though they are powered by the earlier 3.6-liter engine.)
In addition, the contrasting color of the lower aerodynamic body panels differed between the 3.6-liter and 3.8-liter M5 models. On the 3.6-liter examples ,these were painted either Diamond Black metallic (181) or Sebring Grey metallic (229). This changed with the 3.8-liter version to a choice of either Diamond Black metallic (181) or Granite Silver metallic (237). (Note: the change from Sebring Grey to Granite Silver also applies to the 1993 North American-spec E34 M5, which retained the 3.6-liter motor.)
What distinguishes the interior of the E34 M5 from that of a normal E34 5 Series?
Though the basic architecture of the interior is identical to that of any E34 5 Series, the M5 interior does have a few unique items: The unique instrument cluster contains red needles, an oil temperature gauge under the tachometer (instead of an economy gauge) and an M logo between the speedometer and tachometer. Like the E28 M5, there are "M5" trim plates on all four door sills (in one of two versions, depending upon the production date) and a fully-carpeted trunk with a storage compartment on the left side.
All E34 M5s are equipped with sport front seats, identical in shape and adjustment to those fitted as an option to other E34 5 Series models. Power controls were either standard or optional, depending upon the year and market. On European-spec M5s, the seats could be upholstered in a unique M cloth with leather boolsters on 3.6-lier models or a different M cloth with Amaretta suede bolsters on 3.8-liter models, as well as optional leather. Also, all E34 M5s built before September, 1990 have a fixed rear center console that effectively makes them four-seaters. This console became optional in most markets starting with September, 1990 production.
There were five different factory steering wheels available on the E34 M5, depending on the market and production date. Most 3.6-liter models and some early 3.8-liter cars have the three-spoke M-Technic II steering wheel without an airbag but with the M logo on the third spoke. Standard on U.S.-spec M5s and optional in most other markets (including Canada) was the regular airbag-equipped four-spoke BMW wheel. Starting with September, 1992 production, this wheel was upgraded to include the M tri-color stitching on the rim. Beginning with the 1994 model year (09/93 production), E34 M5s could be fitted with either an M-enhanced version of the four-spoke airbag wheel, now including a thicker rim with thumb grips and a revised center pad, or a new non-M three-spoke wheel with an integrated Euro-sized airbag. A leather-wrapped shift knob with an illuminated shift pattern and the M tri-color stripe was fitted as standard to all E34 M5s. Also, the area around the shift lever is unique in that it is recessed for extra storage.
Finally, all E34 M5s have a check control vehicle monitoring system integrated into the instrument cluster and the fourth-generation BMW on-board computer.
What are all the ways that the interior of U.S. and Canadian E34 M5s differ?
All North American E34 M5s are mechanically identical and share the same exterior appearance, with the exception of standard headlight washers on Canadian-spec cars. This feature aside, it is only on the inside that U.S. and Canadian cars can be distinguished from each other. The following are all the ways the two models differ, aside from having metric (Canada) or non-metric (U.S.) instrumentation:
U.S Specification:
Leather trim: Standard on seats only
Fixed rear console: Standard before 09/90 production, then deleted
Heated seats: Optional
Driver’s airbag with knee bolster: Standard
Driver’s three-position seat memory and power steering column adjustment: Not available
Canadian Specification:
Leather trim: Standard on seats only, optional Extended trim with leather on center console, door pulls, glovebox door
Fixed rear console: Standard before 09/90 production, optional after
Heated seats: Standard
Driver’s side airbag with knee bolster: Optional
Driver’s three-position seat memory and power steering column adjustment: Optional
How does the interior of the South African E34 M5 differ from that of the German-built model?
There were no significant differences between the interior of the German-built E34 M5 and those assembled in South Africa, although the level of standard equipment was generally higher on South African models.
How is the 3.8-liter E34 M5's interior different from that of the 3.6-liter version?
The interior of the 3.8-liter E34 M5 is essentially identical to the one found in 3.6-liter models. The main exception concerns the standard cloth upholstery. Early (3.6-liter) E34 M5s that are not equipped with optional leather upholstery have M cloth seats and door panels with leather on the outer bolsters, while the later (3.8-liter) cars have a different type of M cloth on the center part of the seats and door panels with a suede-like Amaretta material on the bolsters.
Also, 3.8-liter M5s have more pronounced door sill plates with the “M5” logo in a style similar to that of the E36 M3. (Note: North American-spec M5s built after 01/92 also have this design.)
What features were optional on the E34 M5?
Like most other M models, the level of standard and optional equipment for the E34 M5 varies significantly from year to year and market to market. Major exterior options (standard in some markets) include power sunroof, metallic paint, heated headlight washers, Shadowline (dechromed) trim and a body-color rear spoiler. Like the E28 M5, the E34 M5's hand-built nature allowed even more variation on the interior. All regular E34 options were available, as well as various special types of upholstery, dash and console trims, and luxury items such as upgraded audio systems, phones, fax machines and televisions.
These special-order items were generally not availble in the North American market, where the E34 M5's option list was confined to heated front seats (standard in Canada), a CD changer, integrated cellular phone and remote locking with alarm (standard from 9/91 production) . One further rare option was the "Four-Seasons" glass moonroof, discontinued as of September, 1990. In addition, Canadian cars could further be fitted with a three-position memory for the driver's power seat and power steering column, extended leather upholstery and the fixed rear center console (standard on all North American cars built before September, 1990).
What types of leather trim were available on the E34 M5?
There were three types of leather trim offered as part of the normal upholstery options for the E34 M5: The most basic included leather only on the seats. This was the only type available on U.S.-spec M5s, where it was standard. In most other markets (including Canada), the interior could be upgraded to "extended leather", which added hide on the center console, door pulls, and glovebox door. Finally, the top-level "complete leather" interior further added leather to the upper dashboard (including instrument cluster surround), A-pillars, upper door panels, sunvisors and rear parcel shelf. Please note that not all upholstery colors were offered with every leather type. See "Color and Upholstery Selections" below.
Special Versions
Were there any special versions of the E34 M5?
There were four official special editions of the E34 M5 sedan: The Cecotto, Winkelhock and "20 Jahre" editions were offered exclusively as left-hand drive European-spec models, while the right-hand drive UK Limited Edition was only sold in the United Kingdom. In addition, a special "NAGHI" edition of the E34 M5 sedan was produced for the Saudi Arabian market and an unofficial special edition of the M5 Touring, known as the "Elekta," was produced exclusively for Italy.
What is an E34 M5 Cecotto edition?
In 1991, BMW asked two of its racing drivers to design their own ideal version of an E34 M5. One of the drivers was multiple Touring Car champion Johnny Cecotto. His ideal M5 was one fitted with a full host of luxury items. BMW M then offered the public a package of features based on this ideal M5.
A total of 22 Cecotto M5s were produced. They were available in either Lagoon Green metallic (266) or Mauritius Blue metallic (287) and included the following special equipment:
-Servotronic power steering
-Full Bicolor Napa leather (Silvergray/Light Silvergray or Parchment/Light Parchment) including the steering wheel hub, column and horn pad
-Wood trim
-Power sunroof
-Heated, power front seats with driver's memory

What is an E34 M5 Winkelhock edition?
In 1991, BMW asked two of its racing drivers to design their own ideal version of an E34 M5. One of the drivers was Joachim Winkelhock, known for his success on the racing circuit with the Schnitzer E30 M3. His ideal M5 was a lightweight edition, stripped of all but the most performance-oriented items. BMW M then offered the public a package of features based on this ideal M5.
A total of 51 Winkelhock M5s were produced, all painted Jet Black (668) with contrasting lower body panels in Sterling Silver metallic (244) and including the following special equipment:
-Smaller battery* (66 volt versus 85 volt)
-Smaller gas tank* (80 liters)
-Reduced sound deadening material*
-Deletion of power rear windows, rear headrests, fog lights, headlight washers, vanity mirrors*

-Evolution front sport seats in M cloth with Anthracite leather bolsters
-Red seat belts front and rear
-Special leather service book pouch, key holder and gold pin
*These changes reduced the curb weight of the Winkelhock M5 by 88 lbs. compared to the standard M5.
In addition, the option list was reduced to the following:
Rear spoiler, power sunroof, rear sunshade (manual), floor mats, radio, Shadowline trim, air conditioning (with 85-volt battery)
What is an E34 M5 "Naghi Motors" edition?
At the request of Naghi Motors, the BMW importer for Saudi Arabia, BMW Motorsport GmbH produced 15 special examples of the 3.6-liter E34 M5 sedan. Known as the "Naghi" edition, these were the final ECE-spec 3.6-liter M5s produced. and were all built in late March and early April of 1992. Like all Gulf-specification E34 M5s, they were built without catalysts and were therefore rated at 318 hp (DIN). Five examples were produced in three different exterior colors each: Jet Black (668), Alpine White II (218) and Lagoon Green metallic (266).
Each “Naghi” edition was fitted with only the following regular options:
-Rear spoiler
-Shadowline trim
-Green windshield stripe
-Velour floor mats
-Air conditioning
-BMW Bavaria Cassette III radio
In addition, each “Naghi” edition was equipped from the factory with the following special equipment:

-Red seatbelts
-M System II alloy wheels (8x17-inch front, 9x17-inch rear)
-Hirschmann phone antenna
Finally, the following additional equipment was added by Naghi Motors once the cars arrived in Saudi Arabia:
-Red leather steering wheel, gear shift knob and parking brake handle
-M tri-color stripes on the front driver-side edge of the hood
-Special door sill plates with the "Naghi Motors" insignia
What is an E34 M5 "20 Jahre" edition?
To celebrate the 20th anniversary of BMW Motorsport, BMW built a limited run of 20 specially-equipped M5s in October of 1992. Based on the 3.8-liter sedan, they are all painted Mugello Red (274) and include several regular options (Nürburgring Package, Shadowline trim, driver-side airbag, power sunroof, headlight washers, air conditioning with automatic air recirculation, BMW Bavaria Cassette III radio with hi-fi speakers), as well as the following special equipment:
-M Technic rearview mirrors
-Contrasting M lower body panels in Jet Black (668)
-M System II wheels with Jet Black "throwing star" covers
-Recaro SR sport seats in special M cloth with Anthracite Amaretta (faux suede) bolsters
-Amaretta-covered steering wheel, shift knob, shift boot and parking brake, all with red stitching
-Carbon fiber trim on dash and door panels

-Plaque on the center console with each individual number in the edition of 20
What is an E34 M5 UK Limited Edition?
To commemorate the end of right-hand drive E34 M5 production, 50 examples of the E34 M5 Limited Edition were assembled between March and June of 1995 in one of two unique color and trim conbinations: Rosso Red metallic (369) with a Champagne extended leather interior and natural poplar wood trim (15 built) or Orinoco metallic (406) with a Bicolor Petrol and Mint extended leather interior and graphite birds-eye maple wood trim (35 built). In addition to a storage net in the passenger footwell, each E34 M5 Limited Editon was further equipped with the three-spoke steering wheel, Shadowline trim, power sunroof, green windshiled stripe, auto-dimming interior mirror, power front seats, headlight washers, air conditioning and radio preparation. A special numbered plaque appears on the center console of each example.
What is an E34 M5 Touring "Elekta" edition?
At the request of several Italian BMW dealers, a limited edition of 20 E34 M5 Touring "Elekta" editions was produced by BMW Individual exclusively for the Italian market in June and July of 1995. These were offered in a choice of two unique color schemes: Sterling Silver metallic (244) with a Marine Blue Nappa leather interior and matching carpeting or British Racing Green (312) with a Hazlenut Nappa leather interior and Mexico Green carpeting. Both schemes also included a black leather dashboard and door tops, but not the leather A-pillar trim, sun visors and Alcantara headliner normally fitted to E34 M5s with the Complete leather option. In addition to a special storage net in the passenger-side footwell, all of these Tourings were further equipped with the three-spoke steering wheel, Shadowline trim, roof rails, dual power sunroof, power front seats with driver-side memory, auto-dimming interior mirror, radio preparation, hi-fi speaker system, headlight washers and automatic climate control with automatic air recirculation. Some examples were also fitted with a special metal shift knob insert inscribed with "Elekta" and each unique car number in the edition of 20.

E34 M540i
Production Versions:
Canadian-specification (LHD), 04/95-07/95
History
What makes the M540i unique?
The E34 M540i is a special 5 Series model produced in 1995 by BMW Individual exclusively for the Canadian market. In essence, this model mates the standard four-liter M60 V8 engine and Getrag six-speed manual gearbox of the 540i with the M-designed chassis and cosmetic enhancements of the final European-spec E34 M5.
Where was the M540i introduced?
The M540i premiered at the 1995 Toronto auto show.
Why was the M540i created?
BMW Canada came up with the idea of the M540i as a way to offer customers a true successor to the E34 M5, which had been discontinued during 1993 (though it continued to be produced for the European market until July of 1995). The basis for the M540i was the 540i six-speed, a model that was already certified for sale in Canada and produced similar power figures to the M5. By adding all the chassis and cosmetic enhancements from the 1995 European-spec M5 but without altering the drivetrain, BMW Canada could offer a model with a comparable appearance and performance to the M5, but without the prohibitive cost of additional emissions and safety certification.
How was the M540i produced?
To create the M540i, BMW M pulled semi-completed examples of the North American-spec 540i six-speed from the Dingolfing assembly line. These cars were then taken to the BMW M works in Garching where they were fitted with the M chassis components and cosmetics.
Production Data
How many examples of the M540i were made?
BMW Individual built 32 examples of the M540i between April and July of 1995.
Does the M540i have a unique VIN sequence?
No. The M540i is technically considered a North American-spec 540i six-speed. Therefore, all 32 examples have chassis numbers within that model's normal sequence.
Drivetrain
What kind of engine powers the M540i?
The M540i is powered by the standard 3982cc M60 V8 used in all E34 540i, E32 740i/740iL and early E31 840Ci models. It has an aluminum block and head with four valves per cylinder. Power is rated at 282 hp (SAE) at 5,800 rpm and 295 lb/ft of torque at 4,500 rpm.
What kind of gearbox does the M540i have?
The M540i utilizes a Getrag Type D six-speed manual gearbox with the following ratios: 4.23 (1), 2.51 (2), 1.67 (3), 1.23 (4), 1.00 (5), .83 (6). This is mated to a 2.93:1 axle ratio and a limited slip differential, except on those examples equipped with the optional ASC+T tracrtion control system, which have an open differential.
Chassis
How is the M540i's chassis different from that of a normal 540i?
The suspension of the M540i is identical to the standard "Nurburgring" chassis of the European-spec E34 M5. It therefore incorporates the following modifications over the normal 540i setup:
-Adaptive M Suspension, an M-tuned version of Electronic Damping Control (EDC) that electronically chooses the optimum shock rates based on sensors that gather road speed, steering input, acceleration/deceleration loads and lateral body movements
-20mm reduction in ride height
-25 percent firmer spring rates
-Self-leveling rear shocks
-Thicker antiroll bars front and rear
-Adjustable rear toe-in
The recirculating ball steering utilizes the E34 M5's quicker ratio (15.6:1) and available ZF Servotronic (vehicle-speed sensitive) power assist.
What size brakes does the M540i have?
The M540i's braking system is the same as that of all E34 M5s built as of May 1994, its four-wheel vented discs measuring 13.6-inches (front) and 12.8-inches (rear) in diameter. In addition, the front rotors incorporate two-piece “floating” calipers. This is the only factory BMW application of these rotors ever offered in North America.
What are the factory wheel and tire sizes for an M540i?
Like all E34 M5s built from May 1994, the M540i is shod with 245/45ZR18 tires on M Parallel Spoke alloy wheels, sized 8x18-inch (front) and 9x18-inch (rear).
Cosmetics
How is the exterior of the M540i different from that of a standard E34 540i?
The M540i's appearance is distinguished from that of the normal 540i by the folowing items:
-Body-color M-Technic front spoiler and rear diffuser
-M aerodynamic rear-view mirrors
-Shadowline (dechromed) exterior trim
-18-inch M Parallel Spoke alloy wheels
-Chrome exhaust tips
-"M540i" decklid badging
-Choice of Avus Blue metallic (276) and Daytona Violet metallic (266) paints, in addition to the standard E34 exterior colors
How is the interior of the M540i different from that of a standard E34 540i?
In addition to all the standard Canadian-spec 540i six-speed equipment for the 1995 model year (headlight washers, air conditioning, power sunroof, power and heated sport seats with driver-side memory, power steering column adjustment, on-board computer, hi-fi speakers, etc.), the interior of the M540i is equipped with the following special features:
-M cloth upholstery with Amaretta suede bolsters (or optional Bison leather)
-carbon fiber interior trim
-M-Technic four-spoke airbag-equipped steering wheel with tri-color stitching
-leather shift knob with M stripe and illuminated shift pattern
-door sill plates with the "M" logo
-dash plaque with each individual car number in the series of 32
What items were optional on the M540i?
Two factory options were offered on the M540i: ASC+T traction control (in place fo the standard limited slip differential) and Bison leather upholstery (in either Black or Light Silvergrey). In addition, a 6-disc CD changer and cellular phone were dealer-installed options.
Special Versions
Were there any special versions of the M540i?
Being a limited model itself, there were no further special editions of the M540i. However, the final example of the M540i (#32 of 32) is unique in that it was ordered with special BMW Individual paint (British Racing Green) and upholstery (Modena Natur Nappa leather with Mexico Green Nappa leather trim).
Though only Canada received the M540i, Australia and the United States (both markets where the 3.8-liter E34 M5 was never offered) also received special versions of the 540i with an M5-derived Nürburgring chassis and unique cosmetic items. These were known as the 540i Manual Limited Edition (Australia) and the 540i M-Sport (USA).
How is the Australian-spec E34 540i Manual Limited Edition unique?
A special production run of 70 right-hand drive E34 540i Manual Limited Edition models was produced for the Australian market between February and July of 1995. These were the only E34 540i models sold in Australia with the six-speed manual gearbox and included all of the standard 540i equipment (dual airbags, remote locking with alarm, green windshield stripe, power sunroof, power front seats with driver-side memory, rear headrests, air conditioning, cruise control, hi-fi speakers) as well as the following special features:

History
What makes the three-liter E36 M3 unique?
The E36 M3 3.0 is the original BMW Motorsport (later called BMW M) version of the E36 3 Series. Available as a coupe, convertible or sedan, it uses one of two 3.0-liter S50 engines, both based to some degree on the standard production M50 powerplant. The European S50 has individual throttle bodies and a more complex cylinder head, while the U.S.-spec S50 more closely resembles the normal production M50 engine. All E36 M3s also have a BMW M-tuned chassis and unique cosmetic items both inside and out. Unlike its E30 M3 predecessor, the E36 M3 was not designed primarily for competition use, but rather as a road-going GT car.
Where was the E36 M3 3.0 introduced?
The E36 M3 coupe was first shown at the 1992 Paris Motor Show. The U.S.-spec version did not appear until the 1994 Los Angeles International Auto Show.
Where was the E36 M3 3.0 built?
All 3.0-liter E36 M3s were built on the regular 3 Series assembly line at the Regensburg factory near Munich with the excpetion of a small batch of coupes assembled in South Africa from German-supplied Semi Knocked-Down kits exclusively for that market.
Production Data
How many versions the 3.0-liter E36 M3 were there?
BMW initially produced the European-spec E36 M3 3.0 only as as a coupe. Convertible and sedan versions were introduced two years later. Each body style was offered in left-hand drive and right-hand drive configurations. There was also a limited run of E36 M3 GT coupes built in both left-hand drive and right-hand drive. The U.S.-spec version of the 3.0-liter M3 was offered only as a coupe, with a choice of manual or automatic transmissions. Finally, there was a small number of South African-spec coupes assembled for the 1994 model year at the Rosslyn, South Africa factory from German-supplied Semi Knocked-Down kits (SKD).
How many of each version were produced?
ECE coupe (LHD): 11,284 built from 03/92 thru 07/95
ECE coupe (RHD): 3,152 built from 03/93 thru 07/95
ECE GT coupe (LHD): 350 built from 02/95 thru 06/95 (plus 6 pre-production in 12/94)
SA coupe (RHD): 748 built in SKD form from 09/93 thru 04/94
USA coupe manual (LHD): 8,515 built from 03/94 thru 12/95
USA coupe automatic (LHD): 1,705 built from 12/94 thru 01/96
ECE convertible (LHD): 1,403 built from 03/94 thru 08/95
ECE convertible (RHD): 572 built from 09/94 thru 08/95
ECE sedan (LHD): 868 built from 06/94 thru 07/95
ECE sedan (RHD): 415 built from 10/94 thru 07/95
How did the U.S.-spec version of the E36 M3 come about?
When the E36 M3 made its European debut in 1992 there were no plans to produce a North American version. Sales of the previous M3, the E30 of 1988-91, had amounted to just under 5,000 units and BMW’s only other North American-spec M car at the time, the E34 M5, was not selling in large enough quantities to justify the addition of another M model in the American market. However, a letter-writing campaign initiated by the BMW Car Club of America sparked such an overwhelming response by the enthusiast BMW community that BMW of North America decided to reconsider. The main issue was price: BMW NA was determined to keep the MSRP down to around $35,000, about the same as the last of the E30 M3s. The only way to meet this price point was to develop a specific version of the S50 engine without the costly individual throttle bodies and continuously variable VANOS valve timing system of the European-spec motor. Just such a car entered production in February, 1994 (as a 1995 model) and went on to be produced in almost equal numbers to the European version despite a production run of only half as many years. (Note: This model was not available in Canada see question below)
What chnaged during the production of the European-spec E36 M3 3.0?
There were no major mechanical alterations to the E36 M3 3.0 during its production. However, the model did receive the following equipment changes:
-M tri-color stitching added to four-spoke airbag steering wheel (9/92 production)
-M-design four-spoke airbag steering wheel offered (9/93 production)
-Passenger-side airbag available (9/93 production)
-Light Silvergrey Nappa leather replaced by Light Grey Nappa leather (9/93 production)
-Alpine White II (218) replaced by Alpine White III (300) (12/93 production)
-Sterling Silver metallic (244) replaced by Arctic Silver metallic (309) (12/93 production)
-Diamond Black metallic (181) replaced by Cosmos Black metallic (303) (3/94 production)
-Violet Blue/Black extended Nappa leather added (3/94 production)
-Classic Red/Black extended Nappa leather added (3/94 production)
-Mugello Red (274) replaced by Bright Red (314) (9/94 production)
-Revised temperature controls for HVAC (9/94 production)
What changed during the production of the U.S.-spec 1995 M3?
Though all 3.0-liter U.S.-spec M3s are officially 1995 models, production actually spanned from March of 1994 thru January of 1996. During that time, the following changes were introduced:
-On-board computer added to option list (mid-1994 production)
-Height-adjustable steering wheel deleted (9/94 production)
-Console Valet with cupholders added (9/94 production)
-Mugello Red (274) replaced by Bright Red (314) (9/94 production)
-Revised temperature controls for HVAC (9/94 production)
-Automatic transmission available (12/94 production)
-Luxury Package option introduced (12/94 production)
-Forged Double Spoke alloy wheels, sized 7.5x17-in. (front) and 8.5x17-in. (rear), added to option list (12/94 production)
-Coded Driveaway Protection introduced (1/95 production)
-Rear spoiler becomes a factory option (was dealer-installed) and adds integrated third brake light (1/95 production)
-All exterior colors available with and without optional Luxury Package (5/95 production)
-Polished finish added to optional forged M Double Spoke alloy wheels (9/95 production)
-Radio changed to version used on 1996 models (11/95 production)
Was the European version of the three-liter E36 M3 ever sold in North America?
Yes. Through an agreement that existed between Canada and several European nations, any car federalized in one country could legally be sold in any of the others. With no North American version of the E36 M3 on the horizon in late 1993, BMW Canada took advantage of this agreement and imported 45 European-spec M3 coupes for the 1994 model year. Pulled at random off the standard assembly line during December of 1993, these cars were fitted with a third brake light and daytime running lights (required by Canadian law), while the rear fog light was deleted. Each car also received a numbered plaque on the inside of the glovebox door.
All paint colors and interior trims from the Euroepan-spec M3 were offered on the 45 Canadian examples. Each was equipped as standard with dual airbags, air conditioning, a green-tinted windshield stripe and an anti-theft AM/FM cassette radio. However, almost the entire European option list (including remote locking, power sunroof, front armrest, rear headrests, power front seats, heated front seats, on-board computer, hi-fi speakers, headlight washers, rear sunshade and forged M Double Spoke alloy wheels) was available at extra cost.
Was the 1995 U.S.-spec M3 ever offered outside the United States?
No, the 3.0-liter, 240-hp version of the M3 was exclusive to the United States for the 1995 model year. Even Canada, which received 45 Euro-spec M3s for 1994, was not offered the M3 again until the 1997 model year.
Drivetrain
What makes the European-spec S50 B30 powerplant unique?
Though based on the regular production M50 24-valve inline-six used in many BMW models of the era, the European version of the S50 B30 engine has a number of unique components developed by BMW Motorsport (later renamed BMW M). These include:
-Increased bore (to 86mm) and stroke (to 85.8mm) for a total of 2990cc
-Increased compression to 10.8:1
-Ported and polished cylinder head
-Individual throttle bodies for each cylinder
-Heavy-duty valve springs
-Continuously-variable VANOS valve timing on the intake stroke
-Bosch Motronic M3.3 engine management control
-Dual mass flywheel
-Free-flowing intake and exhaust systems
In this guise, the S50 B30 produces 286 hp (DIN) at 7,000 rpm and 236 lb/ft of torque at 3,600 rpm. These engines are equipped with dual catalysts for all markets.
How do the U.S. and European versions of the S50 engine differ?
The European and U.S. versions of the S50 B30 powerplant share similar cast iron engine blocks and have an identical capacity of 2990cc. However, the U.S. version (known as the S50 B30 USA) retains the less complex head design and two-stage (non-stepless)VANOS valve timing system of the normal M50 engine upon which it is based. It also does without the European-spec model's individual throttle plates for each cylinder. Compression is slightly lower at 10.5:1. One benefit of the U.S. version is that it retains hydraulic lifters, thus periodic valve adjustments are not needed.
The S50 B30 USA is rated at 240 hp (SAE) at 6,000 rpm and 225 lb/ft of torque at 4,250 rpm.
What kind of gearbox does the 3.0-liter E36 M3 have?
All 3.0-liter E36 M3s regardless of engine type have a ZF Type C five-speed manual gearbox with the following ratios: 4.20 (1), 2.49 (2), 1.66 (3), 1.24 (4), 1.00 (5). This is mated to a limited slip differential (25%) with a 3.15:1 final drive.
In addition, the U.S.-spec 1995 M3 was available with a ZF 5HP18 five-speed automatic transmission as an option starting with 12/94 production. This unit offers three driver-adjustable modes (normal, manual and winter) and uses the following ratios: 3.67 (1), 2.00 (2), 1.41 (3), 1.00 (4), .74 (5). It comes mated to a 3.23:1 final drive with limited slip differential.
Chassis
How is the M3's chassis different from that of a normal E36 3 Series?
The E36 M3’s suspension is based on that of the regular E36 3 Series, with MacPherson struts in front and the multi-link “Z-axle” in the rear. However, BMW M made the following changes when adapting the system to the M3:
-Height decreased by 31mm (1.2-in.)
-Track increased by .55mm (front) and .90mm (rear)
-Firmer shocks and springs
-Reinforced spring mounting plates
-Thicker anti-roll bars
-Revised suspension geometry
In addition, all 3.0-liter M3s have a special M-tuned steering rack with a variable ratio (from 15.4:1 to 19.8:1) and engine-speed-sensitive power steering.
What size brakes does the 3.0-liter E36 M3 have?
All 3.0-liter E36 M3s are fitted with four-wheel vented disc brakes measuring 12.4-inches or 315mm (front) and 12.3-inches or 313mm (rear) in diameter with a thickness of 28mm.
What size wheels and tires was the 3.0-liter E36 M3 equipped with?
For the E36 M3 3.0, BMW M specified 235/40ZR17 tires on all four corners. However, each body style was given a unique set of wheels. The coupe (both Euro-spec and U.S.-spec) wears 7.5x17-inch M Double Spoke cast alloy wheels. A lighter forged M Double Spoke version was optional on European-spec models from the start of production, and became optional on U.S.-spec M3s starting in December, 1994. These are always fitted in a staggered configuration, with 7.5x17-inch wheels in front and 8.5x17-inch wheels in back. A polished version of this wheel was standard on the E36 M3 convertible. The sedan has its own wheel design, the M Contour II, also in the staggered (7.5x17-in./8.5x17-in.) configuration. This wheel is also fitted to the U.S.-spec M3 coupe with Luxury Package, though only in the narrower 7.5x17-inch version.
How does the chassis of the U.S.-spec M3 differ from that of the European version?
The U.S.-spec M3 received the same chassis enhancements as the European-spec model, with the exception of slightly less aggressive spring and shock rates.
Cosmetics
How does the M3 3.0 differ cosmetically from the regular E36 3 Series?
Aside from the wheels, E36 M3s can be distinguished from a normal E36 3 Series by their more aggressive lower body panels consisting of a front airdam with body-color mesh intake, highly-sculpted side valance panels and lower rear diffuser with large-diameter exhuat tips. In addition, the protective side rub strips are wider and contain the “M3” logo, and the side-view mirrors are of the aerodynamic M design. A body-color M-Technic rear spoiler with either the "BMW Motorsport" script or a third brake light could be fitted as an option in most markets (except on convertibles).
How is the three-liter E36 M3 convertible cosmetically different from the coupe?
The three-liter M3 convertible shares all of its M body panels with the M3 coupe. However, the front airdam lacks the black plastic lower lip extension and the M-Technic rear spoiler was never available as a factory option on the open-top model.
How is the three-liter E36 M3 sedan cosmetically different from the coupe?
In order the appeal to a more conservative buyer, the M3 3.0 sedan is fitted with a more restrained M-Technic front airdam. Though similar to the one used on M3 coupes and convertibles, it contains three body-color horizontal slats in place of the mesh intake and (like the convertible) lacks the black plastic lower lip extension. Also, the side valance panels are less heavily sculpted.
How is the U.S. version of the E36 M3 3.0 cosmetically different from the European version?
There are few external differentiators between the two versions. However, like all E36 3 Series sold in America, the M3 is not fitted with ellipsoid headlights or a rear fog light, both standard features of the European version. Also, U.S.-spec models were never available with headlight washers.
How does the interior of the E36 M3 3.0 differ from that of a regular E36 3 Series?
The interior of the 3.0-liter E36 M3 has several special items that are unique to this model: an M instrument cluster with red needles and the M logo, door sill plates with the "M3" insiginia, a black headliner and a shift knob with the M tri-color stripe. All E36 M3s are equipped with the Check Control vehicle function monitoring system.
Several different steering wheels were offered on the E36 M3. Some very early examples have the three-spoke M-Technic II wheel without an airbag, but most have either a non-M three-spoke wheel with a Euro-size airbag or a four-spoke wheel with a full-size airbag. Cars built before September, 1993 use this wheel in the normal BMW design. After that time, the standard airbag wheel was replaced with an M version featuring a thicker rim and raised thumb grips plus a redesigned horn pad and M tri-color stitching on the rim. This was the only wheel available on North American M3s.
Unique to the E36 M3 coupe are M Design sport seats with integrated headrests in either M cloth with Amaretta suede bolsters or Nappa leather with the M tri-color insignia. The M3 sedan and convertible, as well as the U.S.-spec M3 coupe with Luxury Package, have regular BMW sport seats covered in Nappa leather. Luxury Package-equipped coupes and all E36 M3 sedans are further fitted with Burl Walnut wood trim on the center console, shift knob, parking brake handle and door pulls. They also have chrome interior door handles.
How is the interior of the U.S.-spec E36 M3 3.0 different from that of the European version?
The sole item that is unique to the interior of E36 M3s built for the American market is the instrument cluster. Though it shares its red needles and M logo with that of the Euro-spec car, the U.S. version has a 160-mph speedometer (in place of the 280 kph/170 mph unit) and a unique tachometer with a graduated redline and integrated economy-meter (in place of an oil temperature gauge).
Also, standard equipment was more extensive than on the European-market M3, and included:
-Air conditioning
-10 speaker Alpine radio/cassette sound system, prewired for CD changer
-Choice of M cloth/Amaretta suede or Nappa leather seating at no extra cost
What items were optional on the E36 M3 3.0?
European-market E36 M3s could be fitted with almost any 3 Series option including headlight washers, metallic paint, a rear spoiler (not available on the convertible), air conditioning, leather upholstery (standard on the convertible and sedan), power sunroof, power seats, heated seats, manual rear window sunshade, the fourth-generation on-board computer, cruise control and rear headrests.
On U.S. models, options were initially limited to a power sunroof, cruise control and heated front seats. The fourth-generation on-board computer became optional a few months after production began, and forged M Double Spoke alloy wheels were added to the option list by the end of 1994. An M-Technic rear spoiler was a dealer-installed option from the start of production and became a factory option in January, 1995.
What is the Luxury Package for the E36 M3?
The Luxury Package debuted exclusively for the U.S. version of the E36 M3 starting with December 1994. This package, with its more understated exterior trim and more luxurious interior appointments, included the following features:
-M-Technic front spoiler with three-slat, body color air intake and no lower lip
-Less sculpted side valance panels
-M Contour II alloy wheels (sized 7.5x17-in.)
-Eight-way power BMW sport seats
-Nappa leather door panels
-Extended Burl Walnut wood trim including the center console and door pulls
-Chrome interior door handles
-Front armrest
-Cruise control
-On-board computer
-Exclusive (until 5/95 production) choice of Arctic Silver metallic (309) and Boston Green metallic (275) paints
-Exclusive choice of Mulberry and Champagne Nappa leather upholstery
Special Versions
Were there any special versions of the three-liter E36 M3?
Five special versions of the E36 M3 3.0 were created by BMW M, though only three, the M3 GT, M3 GT Individual and M3 Lightweight, can truly be considered production models. The other two, M3 GTR and M3-R, are highly specialized models built in very limited numbers and not generally available to the public.
What is an E36 M3 GT?
The E36 M3 GT is a limited-edition version of the European-market 3.0-liter M3 coupe developed to homologate engine and bodywork enhancements to the equivalent competition model in the FIA GT Series (Division II) and the American IMSA GT Series. A total of 350 examples were produced in left-hand drive form from February thru June of 1995 (in addition to six pre-production vehicles produced in December of 1994) with the following special equipment:
-A retuned version of the S50 B30 powerplant with 264-degree cams, a BMW Motorsport dual-pickup oil pan, duocentric oil pumps and upgraded VANOS software producing 295 hp at 7,000 rpm and 238 lb/ft of torque at 3,900 rpm

What is an E36 M3 GT Individual?
The E36 M3 GT Individual is a special edition of 50 right-hand drive E36 M3 coupes produced for the UK market in July of 1995. Though based mechanically on the standard E36 M3 instead of the more powerful GT version, these cars have the following special features:
-British Racing Green (312) paintwork
-Adjustable front and rear GT spoilers
-Clear front turn signal lenses
-Aluminum doors
-M strut tower brace
-Forged M Double Spoke alloy wheels (7.5x17-in. front, 8.5x17-in. rear)

What is an E36 M3 Lightweight?
The M3 Lightweight (sometimes referred to as the M3 CSL) is a special version of the U.S. model E36 M3 designed for track driving. Approximately 120 were built between July and October of 1995 by BMW Individual (the division of BMW M responsible for special orders). These cars retain the stock 240-hp S50 B30 USA powerplant, though BMW claimed that all engines fitted to the Lightweights were tested to make sure they were operating at the top of the acceptable range.

History
What makes the E36 M3 3.2 unique?
For the 1996 model year, BMW M replaced the E36 M3 3.0 with the faster and more refined 3.2-liter version. For the European market, this model was fitted with the new S50 B32 engine, an evolution of the S50 B30, as well as a six-speed manual gearbox and detail refinements to the chassis. For the U.S. (and later Canadian) market, the M3 received its own powerplant, the S52, plus ASC+T traction control and a host of chassis upgrades. Both versions were also treated to a few cosmetic alterations.
Where was the E36 M3 3.2 introduced?
The 3.2-liter E36 M3 was first shown at the 1995 Frankfurt Motor Show. The North American-spec version did not appear until the 1996 New York International Auto Show.
Where was the E36 M3 3.2 built?
All 3.2-liter E36 M3s were built on the regular 3 Series assembly line at the Regensburg factory near Munich, with the exception of a small batch of M3 3.2 sedans built in BMW’s Rosslyn, South Africa factory from both Semi Knocked Down (SKD) and Complete Knock Down (CKD) kits.
Did Canada receive a version of the 3.2-liter E36 M3?
An E36 M3 powered by the 3.2-liter S52 engine was not introduced in Canada until the 1997 model year (9/96 production). This was the first official Canadian-spec M3 of any kind since the 45 limited-edition European-spec coupes that were sold there in 1994, and the first Canadian E36 M3 to use the North American-spec engine. The 3.2-liter E36 M3 was available in Canada as a coupe or sedan, but never as a convertible. Aside from minor differences in standard and optional equipment (see Production Data below), they are identical to the U.S. versions.
Did BMW ever produce an E36 M3 3.2 Compact?
BMW M GmbH only built one example of an E36/5 M3 Compact (hatchback) in honor of the 50th birthday of Auto Motor und Sport magazine in 1996. In addition to the S50 B32 engine and Getrag six-speed manual gearbox, this car featured a special quad-tip exhaust configuration that previewed the similar arrangement that would later appear on the E36/7 M roadster and E36/8 M coupe. It also included an M-tuned suspension, M3-spec brakes and 17-inch forged M Double Spoke alloy wheels. An M-Technic aero package, M aerodynamic rear-view mirrors and clear turn signal lenses dressed up the Bright Red (314) exterior, while the interior was treated to the M3 instrument panel, Recaro racing seats in black cloth with red four-point seatbelts, plus an Alcantara-wrapped steering wheel and gearshift knob. It is not known if this car still survives.
Production Data
How many versions the 3.2-liter E36 M3 are there?
The E36 M3 3.2 was immediately produced in coupe and convertible forms, as well as a four-door sedan. Like the original 3.0-liter E36 M3, 3.2-liter models were equipped with two different powerplants, one for North America (S52) and a second for Europe and the rest of the world (S50 B32). The latter model was offered from the start in all three body styles, and in both left-hand drive and right-hand drive configurations. Of these, a small run of right-hand drive sedans was assembled in South Africa from German-supplied components in late 1996, and a further number were fully built there during 1997 and 1998.
The North American-spec E36 M3 3.2 was initially offered only in the U.S. market and only as a coupe. For the 1997 model year (September, 1996 production), a North American-spec M3 sedan was added and Canada received the S52-powered E36 M3 for the first time. An S52-powered E36 M3 convertible was added exclusively to the U.S. market starting with March, 1998 production. Though all North American E36 M3 3.2 coupes were fitted with a manual gearbox, both the sedan and convertible could be ordered with a ZF five-speed automatic transmission.
How many of each version were built?
ECE coupe (LHD): 6,117 built from 09/95 thru 12/98
ECE coupe (RHD): 2,845 built from 11/95 thru 12/98

What is an E36 M3 Evolution?
To better distinguish the 3.2-liter E36 M3 from its 3.0-liter predecessor, BMW GB marketed the E36 M3 3.2 as the M3 Evolution within the United Kingdom. Aside from its right-hand drive configuration, it is mechanically and cosmetically identical to other European-spec 3.2-liter M3s.
How does the South African-produced E36 M3 sedan differ from the European-spec model?
The South African-spec E36 M3 sedan is essentially identical to the European-spec right-hand drive model but utilizes a low-compression version of the S50 B32 engine designed for low-octane South African fuel that produces slightly less power and torque (see Drivetrain below).
What changes were made to the European-spec E36 M3 3.2 during its producton?
The only major mechanical change during the production of the Euro-spec E36 M3 3.2 was the addition of the Sequential M Gearbox (SMG) option in 1997. In addition to SMG, various minor upgrades were introduced before production ended in late 1999 including:
-Restyled grille and side marker turn signals (9/96 production)
-Three-spoke M steering wheel available (9/96 production)
-Byzanz metallic available (9/96-8/97 production, sedan only)
-Side impact airbags available on sedans (1/97 production)
-Side impact airbags available on coupes and convertibles (9/97 production)
-Illumination added to M shift knob (9/97 production)
-Imola Red (405) paint available (3/98 production)
-Titanium Silver metallic (354) available in place of Arctic Silver metallic (309) (3/98 production)
-Fern Green metallic (386) available in place of Boston Green metallic (275) (3/98 production)
-Dark Beige leather upholstery available (9/98 production)
-In dash CD player available in some markets (9/98 production)
What changes were made to the North American-spec E36 M3 3.2 during its producton?
Though there were no further mechanical changes to the North American-spec E36 M3 after the 1996 model year, a number of equipment revisions occurred before production ended in August 1999. These included:
-Restyled grille and side marker turn signals (9/96 production)
-Byzanz metallic available (9/96-8/97 production, U.S-market sedan only)
-Side impact airbags available as an option for sedans (1/97 production)
-Power front seats available as individual option (3/97 production, already offered in Canada)
-Luxury Package option discontinued (9/97 production)
-Side impact airbags standard on all body styles (9/97 production)

-Imola Red (405) paint available (3/98 production)
-Titanium Silver metallic (354) offered in place of Arctic Silver metallic (309) (3/98 production)
-Fern Green metallic (386) offered in place of Boston Green metallic (275) (3/98 production, not available on sedans)
-Radio updated from Alpine C33 to Alpine C43 (9/98 production)
-Sand Beige leather upholstery offered (9/98 production)
How does the Canadian-spec E36 M3 differ from the U.S. version?
After a two-year hiatus, the E36 M3 returned to the Canadian market for the 1997 model year. Unlike the 45 European-spec E36 M3 coupes that were sold in Canada during 1994, the 3.2-liter version was powered by the same S52 motor as the U.S.-spec model and was offered as a coupe or sedan. However, it differed from the U.S. model in the following ways:
-"Floating" front brake rotors standard (identical to the European-spec M3)
-Manual transmission only (no automatic option for the sedans
-Metric instrumentation
-Daytime running lights
-Three-spoke M steering wheel included from start of production
-Tilt steering wheel
-Standard power sunroof and cruise control
-Standard front armrest
-Standard split-folding rear seats (coupe and sedan)
-Optional heated front seats include headlight washers
-Optional power front seats offered from start of production
-Byzanz metallic paint not offered
-M cloth/Amaretta interiors still offered on coupes afterr 8/97
-Magma, Mulberry and Modena Natur Nappa leather interiors discontinued after 8/97
Drivetrain
How is the Euro-spec M3's 3.2-liter engine (S50 B32) different from the previous version (S50 B30)?
When creating the 3.2-liter M3 engine, BMW M relied upon much of the experience it had gained when designing the V12 engine for the McLaren F1 supercar. In the end, the S50 B32 incorporated the following improvements over the S50 B30 engine used in the original Euro-spec E36 M3:
-Increased bore to 86.4mm (from 86.0mm) and lengthened stroke to 91.0mm (from 85.8mm) for a total capacity of 3,201cc (from 2,990cc)
-Increased compression ratio to 11.3:1 (from 10.8:1)
-Advanced BMW/Siemens MSS50 engine management system able to compute 20 million instructions per second
-Double VANOS continuously variable valve timing on both intake and exhaust strokes
-Lightweight pistons
-Improved dual-mass flywheel
-Graphite-coated conrods
-Larger inlet valves
-More efficient intake and exhaust systems
-Second oil pump
The result of these changes boosted horsepower from 286 hp (DIN) at 7,000 rpm to 321 hp (DIN) at 7,400 rpm. Maximum torque also increased from 236 lb/ft at 3,600 rpm to 258 lb/ft at 3,250 rpm. This was the first street-legal BMW engine to achieve over 100 hp per liter.
How does the South African-spec S50 B32 engine differ from that of the European-spec version?
Due to low-octane fuel requirements, the S50 B32 motors produced for South Africa utilize different pistons which result in a reduced compression ratio of 10.5:1. These engines produce 310 hp (DIN) at 7,400 rpm and 251 lb/ft of torque at 3,250 rpm.
How is the North American 3.2-liter M3 engine (S52) different from the 3.0-liter (S50 B30 USA)?
Unlke the Euro-spec S50 B32, the S52 powerplant is an evolution of the standard production M52 engine. However, it incorporates the following changes over its S50 B30 USA predecessor:
-Increased bore to 86.4mm (from 86.0mm) and increased stroke to 89.6mm (from 85.8mm) for a total displacement of 3,152cc (from 2,990cc)
-More finely balanced camshafts
-Valve lifters, springs and spring seats with reduced mass
-Revised intake and exhaust systems
-OBD II (On-Board Diagnostics, version II) compliance
-Horsepower unchanged at 240 hp (SAE) at 6,000 rpm
-Torque increased to 236 lb/ft at 3,800 rpm (up from 225 lb/ft at 4,250 rpm)
NOTE: E36 M3s equipped with the ZF five-speed automatic transmission are rated at 225 lb/ft of torque at 3,800rpm.
What kind of gearboxes does the 3.2-liter M3 use?
There were four different transmissions used on 3.2-liter M3s. European-spec models have a Getrag six-speed manual transmission with the following ratios: 4.23 (1), 2.51 (2), 1.67 (3), 1.23 (4), 1.00 (5), .83 (6). This same gearbox was later used (with the same ratios) as the internals of the Sequential M Gearbox (SMG).
The North American-spec 3.2-liter E36 M3 retains the ZF Type C five-speed manual gearbox of the 3.0-liter version, with the same internal ratios: 4.20 (1), 2.49 (2), 1.66 (3), 1.24 (4), 1.00 (5). Starting with the 1997 model year, the ZF 5HP18 five-speed automatic returned as an option with the same internal ratios used on the 3.0-liter model: 3.67 (1), 2.00 (2), 1.41 (3), 1.00 (4), .74 (5).
All 3.2-liter M3s equipped with a manual gearbox (including SMG) use a shorter 3.23:1 final drive and limited slip differential. North American-spec M3s with the ZF five-speed automatic transmission have an even shorter 3.38:1 rear end, also with limited slip. In addition, all 3.2-liter North American-spec E36 M3s are equipped with Automatic Stability Control plus Traction (ASC+T) which can apply the brakes and/or reduce engine power in order to maintain traction. It includes an orange warning light under the M logo in the instrument cluster and can be switched off via a console-mounted button.
What is the Sequential M Gearbox (SMG)?
In 1997, BMW introduced the Sequential M Gearbox (SMG) as an option on the European-spec E36 M3 in some markets. Using the internals of the Getrag six-speed manual gearbox, SMG employs an electronic clutch operated by a magnetic valve that is triggered by pulling or pushing on the gear lever. Two further valves operate a pair of hydraulic cylinders that electronically engage each gear, thus allowing for shifts to occur in as little as 0.4 seconds. The SMG electronics are integrated with the Siemens engine management system to put the engine and gearbox in synch. The system includes an automatic mode, gear indicator in place of the engine oil temperature gauge below the tachometer, and a flashing upshift light under the M logo in the instrument cluster.
Chassis
What chassis upgrades were made to the 3.2-liter E36 M3 compared to the 3.0-liter model?
All 3.2-liter E36 M3s incorporate the following chassis revisions compared to the 3.0-liter version:
-Revised suspension geometry with increased front castor
-Firmer springs and shocks
-Stronger wheel hubs
-Front anti-roll bar linked to struts for lighter weight
-Quicker steering ratio (mean reduced from 17.6:1 to 15.6:1)
Note: European-spec E36 M3 3.2 sedans utilize the same suspension settings as the E36 M3 3.2 coupe.
What size brakes does the 3.2-liter E36 M3 have?
All 3.2-liter E36 M3s are fitted with four-wheel vented disc brakes of the same size as the E36 M3 3.0: 12.4-inches or 315mm (front) and 12.3-inches or 313mm (rear). However, European-spec and Canadian models also utilize two-piece front "floating" rotors.
Why was the U.S. market denied the “floating” front brake rotors?
The U.S. market was denied the more efficient two-piece rotors offered in the rest of the world because BMW of North America was concerned that, if not properly maintained, the rotors presented the possibility of failing, thus creating a legal liability.
What are the factory wheel and tire sizes for the M3 3.2?
For all versions of the 3.2-liter E36 M3, BMW M replaced the previous model's 235/40ZR17 tires with a staggered setup, specifically narrower 225/45ZR17s in the front and wider 245/40ZR17s in back. The tires are mounted on one of three wheel designs, all measuring 7.5x17-inch (front) and 8.5x17-inch (rear).
European-spec models continue to utilize one specific wheel design for each body style: M Double Spoke II for the coupe, forged M Double Spoke with a polished finish for the convertible (optional on the coupe) and M Contour II for the sedan. On North American models, the M Double Spoke II became the standard wheel for all body styles, with the forged M Double Spoke and M Contour II as options. The latter was fitted to all M3s equipped with the optional Luxury Package and became an individual option as of 9/97 production.
Cosmetics
What distinguishes the 3.2-liter E36 M3 cosmetically from the 3.0-liter version?
The E36 M3 3.2 can be identified from the 3.0-liter version by the following features:
-Black mesh front airdam insert in place of the body-color version
-M Double-Spoke II alloys in staggered 7.5x17-in. (front) and 8.5x17-in. (rear) sizes (not available on the European-spec convertible or sedan)
-Dakar Yellow II (337) offered in place of Dakar Yellow (267)
-Techno Violet metallic (299) offered in place of Daytona Violet metallic (266)
-Estoril Blue metallic (335) offered in place of Avus Blue metallic (276)
In addition, European-spec models are further enhanced by:
-Aluminum doors (coupe and convertible only)
-Clear turn signal lenses
-Third brake light in rear window or on rear spoiler
Note: All European-spec E36 M3 3.2 sedans share the mesh front airdam insert with the other M3 models but retain the less sculpted side valance panels. Like the 3.0-liter versions, both the European-spec sedan and convertible lack the black lower lip extension under the front airdam.
How is the interior of the E36 M3 3.2 different from that of the 3.0-liter model?
Though essentially identical in design and equipment to the earlier model, the interior of the 3.2-liter E36 M3 differs in the following ways:
-Restyled M cloth upholstery (coupe only)
-Shift knob with "M" logo instead of M stripe
-Leather door inserts included with leather upholstery on all models
-Magma leather interior in place of Champagne leather interior (only with Luxury Package on North American-spec cars built before 9/97)
-Modena Natur leather interior available
-Dark Beige leather interior available (from 9/98)
-Hazlenut leather interior available (not for North America)
In addition to the above M3-specific upgrades, the 3.2-liter M3 interior benefits from the following improvements made to most E36 3 Series models as of September 1995 production:
-Automatic climate control in place of manual system
-One-touch feature added to the optional power sunroof
-Revised audio systems and optional Harman/ Kardon upgrade with 320 watts and 6-disc CD changer (optional in most markets)
-Console-mounted door lock switch added (North American models only)
-Redesigned Console Valet (North American models only)
Was the optional Luxury Package continued on North American 3.2-liter M3s?
Yes. The Luxury Package option of the 1995 North American M3 continued unchanged (with the exception of additional leather on the seatbacks) for the later 3.2-liter model, but only on those built before September, 1997 (1996 and 1997 model years). The package was discontinued starting with the 1998 model year (9/97 production), at which time the front armrest became standard equipment (already standard in Canada) and the M Contour II wheels were offered as a no-cost option.
What items were optional on the E36 M3 3.2?
The option list of the 3.2-liter E36 M3 continued largely unchanged from that of the 3.0-liter model, with the exception of a few new items including: Harmon/Kardon audio system, door-mounted side airbags (standard in North America from 9/97 production), power rear vent windows for the coupe (not available in North America), Extended Burl Walnut wood interior trim for the coupe and convertible (not available in North America), and the SMG gearbox (not available in North America).
How do the South African E36 M3 sedans differ cosmetically from the German-built versions?
The South African-built E36 M3 sedan appears essentially identical to that of the German-built model though it is equipped with the black lower lip extension on the front airdam, sculpted side valance panels and forged M Double Spoke alloy wheels, none of which were officially available on European-spec M3 sedans. The interior of the South African model is essentially identical to the German-built version and is fitted with most available features as standard equipment including Nappa leather upholstery, wood trim, cruise control, power seats, on-board computer and premium sound system.
Special Versions
Were there any speical versions of the 3.2-liter E36 M3?
There were two official special editions of the 3.2-liter E36 M3, both introduced in late 1998. A limited edition of 50 right-hand drive M3 coupes was produced by BMW Individual exclusively for the United Kingdom to commemorate the end of E36 M3 production. In addition, 120 right-hand drive E36 M3 coupes and convertibles with special equipment were produced for the Australian market in order to commemorate 25 years of BMW Motorsport.
What distinguishes the UK-market E36 M3 Special Edition coupe?
BMW GB celebrated the end of E36 M3 production with a special edition of 50 UK-market M3 coupes in late 1998. Although mechanically identical to the standard model, these were all painted Imola Red (405) and featured additional front "splitters" below the standard airdam, the complete M3 GT-spec rear spoiler with third brake light and the forged M Double Spoke alloy wheels. The interior was trimmed in Bicolor Imola Red leather with Anthracite Amaretta suede bolsters and was equipped with a special M steering wheel featuring red stitching on the rim. Similar stitching appeared on the parking brake handle. All examples were further equipped with side airbags, power sunroof, power front seats, power rear vent windows and the Harmon/Kardon audio system.
What distinguishes the Australian-market E36 M3 Anniversary Edition?
The Australian-market E36 M3 Anniversary Edition coupes and convertibles were produced for 1999 to celebrate 25 years of BMW M GmbH.
