BMW M1 E26

You are here: Home >> BMW M history >> BMW M1 E26

Between 1978 and 1981, there were 455 BMW M1's manufactured by BMW Motorsport. The M1 with its throaty 6 cylinder engine and great styling makes it an easy car to love. However, since the vehicle hasn't been manufactured since 1981, it makes the car hard to maintain.

Much speculation surrounded the BMW Motorsport Division in 1976 on the development of a GT race car for homologation in Group 4 and Group 5 racing. To qualify, BMW had to build at least 400 identical cars in 24 months. The car became known as the "Mid-Engined BMW M1 Project" (E26) and was started in 1976 and completed in 1980. Though conceived as a "homologation special" for production-class sports-car competition, it was never actually campaigned by the factory, whose motorsport policy veered toward building Formula 1 engines soon after the M1 was finalized. In the end, only 450 examples were built, almost all of them fully equipped road cars. Needless to say, they've already become prized collector's items.

The BMW M1 E26 (which stands for "mid-engine car, first type") originated in 1975 as BMW's counterattack against the Porsche 911s then cleaning up in various sports-racing series. Even so, the only part BMW actually contributed was the engine: a much-modified 4-valves-per-cylinder version of its straight six, designated M-88.

Aside from the gullwing BMW Turbo Concept of 1972, BMW had no experience with "middies," so it hired Lamborghini in Italy to design, develop, and produce BMW M1. Giorgetto Giugiaro's Ital Design (then also involved with the ill-starred DeLorean) was contracted for bodywork styling and construction.

Ital Design was told to retain some "BMW identity," which explains the use of the familiar "twin-kidney" grille motif. Still, the overall result was somewhat heavy-handed compared to Paul Bracq's Turbo (especially around the rear quarters), lacking its grace and excitement.

The use of Italian specialist know-how should have worked brilliantly, but it didn't. Lamborghini welcomed contracts like this because it was on the financial brink at the time. As if by design, it slipped over the edge shortly after the M1 was locked up, leaving BMW no choice but to regroup. Accordingly, construction was farmed out to two other Italian firms: Marchesi, for the multi-tube chassis, and Trasformazione Italiana Resina, for the fiberglass body. Final assembly was shifted to Baur, the German coachbuilder long associated with BMW.

But by then it was 1979 (the BMW M1 debuted at the Paris Salon in October '78) and BMW was wearying of a project that wasn't likely to generate the publicity -- or victories -- expected of it. The BMW M1's sole moment in the competition spotlight came with the 1979-80 "Procar" series, a sort of European International Race of Champions staged before major Grands Prix. In it, F1 drivers competed against each other and a few non-GP pilots in identically prepared BMW M1s, a sort of pre-race side show. It was almost as if BMW was ashamed of what it had done.

And more's the pity, because the BMW M1 was a superb modern supercar by any standard. As in Lamborghini's Miura and Countach, the engine sat longitudinally behind a two-seat cockpit to drive the rear wheels via a 5-speed transaxle (by ZF). Suspension was naturally all-independent, with coil springs and twin A-arms at each corner.

Brakes were big discs all around, while massive 16-inch-diameter wheels and tires were wider at the rear than at the front, as is common in tail-heavy high-performers. The results of all this were vice-free handling, very high cornering grip, and excellent stopping power -- in short, real racetrack ability.

That's hardly surprising when you consider that the BMW M1 was developed in three versions: a 277-horsepower road car, built mainly to satisfy the 400-unit homologation minimum; a Group 4 racer with 470 bhp and suitable body and chassis modifications; and a Group 5 car with about 850 bhp from a reduced-capacity (3.2-liter) turbocharged engine (the others had normally aspirated 3.5-liter powerplants). The Group 4 version was the one run in Procar.

A BMW M1 became one of the BMW art cars collection. It was painted by Alexander Calder and was racing in the 24 Hours of Le Mans in 1979

"Production" BMW M1s were pretty plush, their comprehensive equipment running to air conditioning and full carpeting. They were -- and are -- as nice on the road as any Ferrari Boxer and probably better built. The highly reliable 24-valve M-88 engine is another plus for would-be owners. In fact, this is a pretty young power unit with a lot of development potential as yet unexplored. As proof, a revised rendition powers the limited-production M5 sedan and M635CSi/M6 coupe built by BMW's Motorsport division.

Production Notes:
(Provided by the M1 Register)

  • First car completed on July 10th, 1978
  • Last car completed on Feb.13th, 1981
  • All VINs have the same 14-digit prefix (WBS59910004301XXX) with individual 3-digit suffices. The entire production range used numbers 001 to 460, with seven numbers never used (045 to 049, 428, 431) and two Group 5 race cars built without VINs.

Production Breakdown:

  • 1979 - 79 cars (41 road, 38 race)
  • 1980 - 188 cars (178 road, 10 race)
  • 1981 - 188 cars (180 road, 8 race)

Total: 455 cars (399 road, 56 race)
