Production Data

Versions

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 (ECE, non-catalyst) - 5,187 produced from 03/86 through 08/89
  • European-spec (ECE, catalyst) in 195 hp (early) form - 3,544 produced from 05/86 through 05/89
  • European-spec (ECE, catalyst) in 215 hp (later) form - 1,914 produced from 09/89 through 12/90*
  • North American-spec (NA, catalyst) - 5,300 produced from 03/87 through 12/90


The remaining three were limited editions built to homologate updates to the engine and aerodynamics for racing purposes:

  • Evolution I (ECE, non-catalyst) - 505 produced 02/87 through 05/87**
  • Evolution II (ECE, non-catalyst) - 501 produced from 03/88 through 06/88
  • Sport Evolution (ECE, catalyst) - 600 produced from 12/89 through 03/90


There were also four further special editions with mainly cosmetic variations:

  • Tour de Corse
  • Europa Meister 88 (ECE, catalyst) - 148 produced from 10/88 through 11/88 (includes the French E30 M3 "Tour de Corse" edition)
  • Johnny Cecotto (ECE, catalyst) - 480 produced from 04/89 through 07/89
  • Roberto Ravaglia (ECE, catalyst) - 25 produced in 07/89 (includes the Swiss E30 M3)


In addition to the coupe, an E30 M3 convertible was assembled by hand in limited numbers.


VIN

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.


Changes (European)

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 colour, trim and option variations.


Changes (North American)

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 ellipsoid 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 on U.S.-spec cars and optional in Canada, plus Zinnaber Red (138) and Salmon Silver metallic (203) were replaced by Brilliant Red (308) and Sterling Silver metallic (244). The final 1991 models entered production in June of 1990 with no changes.

Drivetrain

S14

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.


Versions

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 Evolution, 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.


Gearbox

Two different Getrag 260 five-speed manual gearboxes were used:

  • European-spec: Close-ratio version with a direct top gear and a “dogleg” shift pattern
  • North American-spec: Overdrive unit (shared with the E30 325i) with a standard “H” layout


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.


Europe vs North America

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

Suspension

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.


Steering

The E30 M3 has a power-assisted rack-and-pinion steering system with an overall ratio of 19.6:1, which is slightly quicker than the normal E30 ratio of 20.5:1.

Brakes

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.


Wheels

There were two wheel and tire combinations available for the E30 M3. A 7x15-inch cross-spoke alloy wheel with 205/55VR15 tires was the standard wheel on European-spec models and was also fitted to all North American-spec examples. However, the Evolution II, Sport Evolution and Cecotto/Ravaglia special editions were equipped with 225/45ZR16 tires on 7.5x16-inch alloys of the same cross-spoke design. This larger wheel and tire package could also be ordered as a factory option on regular Euro-spec M3s.


Cosmetics

Exterior

Because the E30 M3's shape had to be homologated for racing, all exterior body panels except the bonnet are unique to this model. The front wings 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 boot 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 boot lid.

Europe vs North America

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.

Interior

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.

Europe vs North America

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.

Canada vs U.S

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.

Optional Extras

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.

Identifying an M3

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. A total of 505 examples were produced with consecutive ViNs (2190283 through 2190787) during March and April of 1987.

M3 Evolution II

The E30 M3 Evolution was followed by the E30 M3 Evolution II, 500 of which were built in the Spring of 1988. (NOTE: This model is officially known simply as the "M3 Evolution", since BMW M considers the 505 examples of the first M3 Evolution produced in 1987 as a slight variation on the regular M3 and not a separate edition in its own right.) Unlike the first Evolution, the E30 M3 Evolution II received significant mechanical upgrades to its S14 motor (identifiable by unique valve covers in white with tri-color Motorsport stripes). 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 and 181 lb/ft of torque, both at the same rpm as the standard non-catalyst S14 motor. The close-ratio Getrag 5-speed manual gearbox carried over unchanged, though the final drive was reduced slightly from 3.25:1 to 3.15:1. Larger 7.5x16-inch alloy wheels with 225/45ZR16 tires, normally an extra-cost option on the standard M3, were fitted as standard to the Evolution II. However, there were no alterations to the suspension or brakes.

The exterior of the Evolution II can be easily identified by its deeper front airdam, additional rear lip spoiler on the trunk lid and front brake cooling ducts in place of foglights . In addition, thinner window glass, plus a lightened trunk lid and bumpers, reduced weight by 22 pounds. The E30 M3 Evolution II was offered only in 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 an M foot rest and door sill plates with the "M3" insiginia were included. Finally, a special dashboard plaque denoting the specific number of each example out of 500 was fitted to every Evolution II. All features from the normal M3 option list were also offered on the M3 Evolution II at extra cost, with the exception of the green-tinted windshield stripe, which was standard equipment.

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).

M3 Tour de Corse edition

The Tour de Corse was a special edition of the E30 M3 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. A total of 50 were produced, each based on the E30 M3 Evolution I and therefore equipped with the "E-stamped" cylinder head. Only one paint and upholstery combination was offered: Diamond Black metallic (181) with a Black leather interior (0203). In addition, each Tour de Course was equipped with a high level of factory equipment: central locking, power sunroof, power windows, headlight washer + wipers, interior headlight aim adjustment, on-board computer and velour floor mats. In addition, BMW France retrofitted each Tour de Course prior to delivery with 7.5x16-inch cross-spoke alloy wheels, an M footrest, door sill plates featuring the "M3" logo, and tri-color M stripe lapels on each of the four seats. Finally, each example was given two "Tour de Corse" exterior badges, one in place of the standard M3 badge on the grille and another on the left side of the trunk lid, plus a numbered plaque on the center console bearing the signatures of rally drivers Bernard Beguin and Jean-Jacques Lenne.

M3 Europameister edition

BMW celebrated the dominance of its E30 M3 in the 1988 Touring Car season with a limited run of 148 "Europameister" edition road cars built from October through December of that year. Based on the regular production M3 with the 195-hp catalyst-equipped S14 engine, each was painted Macao Blue metallic (250) and most were equipped with a Silver extended Nappa leather interior with hide covering the center console and special diagonally-pleated door panels, plus M-stripe lapels on all four seats. A complete Silver Nappa leather interior (including the entire dashboard, glovebox door and steering wheel) was offered as a rare (and expensive) option. In addition, the Europameister interior included door sill plates with the "M3" insignia and an "M" foot rest for the driver. A special plaque on the center console read "Europameister 1988 auf BMW M3" and was signed by driver Roberto Ravaglia. Most examples of the Europeameister were heavily optioned, though additional standard equipment over the normal M3 included only the 7.5x16-inch alloy wheels, green-tinted windshield stripe and power windows.

M3 Cecotto edition

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 catalyst-equipped 2.3-liter S14 motor, still rated at 170 lb/ft of torque (though now peaking at a slightly lower 4,600 rpm). This engine, which would become standardized on European-spec M3s beginiing in September of 1989, can be identified in the Cecotto by its body-color valve cover. All other mechanical aspects of the Cecotto edition are identical to the standard E30 M3.

The M3 Cecotto was offered in the same three exterior color choices as the E30 M3 Evolution II: Misano Red (236), Macao Blue metallic (250) or Nogaro Silver metallic (243). It also featured the M3 Evolution II front and rear spoilers, and is further distinguished by its thinner rear window glass, chrome tailpipes, and 7.5x16-inch alloy wheels with unique metallic black centers. However, unlike the M3 Evolution II, the Cecotto does not include the front brake cooling ducts in place of fog lights.On the inside, the standard BMW sport seats were trimmed in a special Anthracite or Silver M-Technic cloth with Bison leather bolsters. As an alternative, Black Bison leather, Black extended Nappa leather or Silver extended Nappa leather could be specified at extra cost. Additional special interior features included door sill plates with a color "M3" insignia, an M footrest for the driver, an illuminated leather 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 in the series out of 505. (In fact, 478 E30 M3 Cecottos were built in total, in addition to 26 nearly identical Ravaglia editions see below, for a grand total of 504 examples). All M3 Cecotto and Ravaglia editions were further equipeed with the green-tinted windshield stripe, power windows, internal headlight aim adjustment, on-board computer II and the cassette storage box, while all available equipment from the regular E30 M3 option list was offered at extra cost.

In addition to the initial 504 examples of the E30 M3 Cecotto and Ravaglia editions, the Swiss market later received its own special series of E30 M3 Cecotto models. These were produced in two batches, the first in October and November of 1989, and the second in April and May of 1990. A total of 80 examples were built, each identical in specification to the earlier M3 Cecotto edition, aside from being fitted with a special 211-hp (DIN) version of the S14 motor tailored for Swiss emissions regulations, as well as the later M-Technic II steering wheel that was introduced on all E30 M3s for the 1990 model year. Though equipped with a special center console plaque that bears the signature of Johnny Cecotto, the Swiss edition is not individually numbered.

M3 Roberto Ravaglia edition

Instead of the E30 M3 Johnny Cecotto edition, the U.K. market received only the E30 M3 Roberto Ravaglia edition, which was essentially an identical car except for the signature of a different BMW factory race driver on the numbered plaque. A total of 26 examples were produced, 16 in Misano Red (236) with an Anthracite M cloth and Bison leather interior, 9 in Nogaro Silver metallic (243) with a Silver M cloth and Bison leather interior, and one single example in Macao Blue metallic (250) with an Anthracite M cloth and Bison leather interior.
