Drivers were equally aggressive, not least as a result of the world’s best Formula 1 stars had been pitted in opposition to one another. The 5 best-ranked drivers in each Formula 1 race got a spot in a Procar cockpit, offered by BMW motor sport.

The BMW M1 is the first automotive to be solely developed by BMW M and employs a 3,453 cc (3.5 L) M88/1 petrol six-cylinder engine with Kugelfischer-Bosch mechanical gas injection and Magneti-Marelli ignition system.

Road Legal Racing Automotive
Despite further wing extensions and the lowered chassis, the optics of the racing model weren’t all that different from its brother on the highway. After its founding in 1972, BMW Motorsport GmbH established its status by way of worldwide successes achieved through the BMW 2002 and BMW three.0 CSL. These successes could be impressively underpinned by the efficiency of the BMW M1. During a TV look in early 1978, Jochen Neerpasch, then chief govt of BMW Motorsport GmbH, offered the racing version of the BMW M1, bedecked for the primary time in the traditional colours of white, purple and blue. The resulting automotive was bought to the general public, from 1978 to 1981, as the BMW M1.

The fibre glass body of the M1 was manufactured by Italian firm Italina Resina which was situated in Modena, Italy. The body of the automobile was completed by Italdesign at their manufacturing facility positioned in Turin along with the inside. The ventilated brakes of the automotive measured 300 mm (eleven.eight in) on the entrance and 297 mm (11.7 in) at the rear and were constructed from metal. The M1 used special Campagnolo alloy wheels measuring 7×16-inches at the front and 8×16-inches on the rear fitted with Pirelli P7 tyres (having sizes of 205/55 VR15 on the front and 225/50 VR15s at the rear).
When BMW’s engineers made it streetable, they didn’t have to worry about handling and stability—they’d it in spades. Although your legs lie virtually parallel to the ground, and aimed inboard slightly to clear the wheel wells, your torso sits comfortably sedan-vertical. From this position, all of the controls are an easy reach, and visibility is superb except for the rear quarters. Even the engine louvers, which are initially annoying, appear to fade into close to transparency with time.
Two were light-weight spaceframe models from the outlets of Peter Sauber, who would later gain fame as a Formula One team owner and staff supervisor for the Mercedes Group C effort. They had been ninety kilograms lighter than the opposite Group 5 vehicles, which had been ProCar conversions. This difference was bourn out in qualifying occasions as the #50 BASF and #52 Wurth entries have been inside three/100ths of a second of each other, and practically eight seconds forward of the #fifty one ZOL Auto and #53 SDC Builders entries. The #seventy one and #seventy two Group 4 M1’s netted first and second at school, explainable by the low number of class entries that year. The maiden outing was a attempting one, because the colourful M1 required replacement of all four brake discs, the clutch, in addition to a gearbox rebuild. Running half the race on 5 cylinders, it was miraculous that the automobile completed sixth general, and only twenty-two laps behind the winners.
