When trimmed down to a sporty 1020 kilogrammes, the BMW M1 Procar accelerated from 0 – 100 km/h in 4.5 seconds and was capable of a top speed of around 310 km/h. Thus equipped, Marc Surer circulated the Nürburgring’s legendary Nordschleife in just 7:55.9 minutes.
However, the BMW M1 built according to Group 4 regulations was not available only to five Formula 1 drivers per race for the Procar one-make cup. As a ready-to-use racing car, the car was available for purchase directly from the factory for 150,000 German marks. Renowned tuners such as Schnitzer and Heidegger availed themselves of this offer.
The racing car was produced in several locations. The pre-assembled BMW M1 came either directly to BMW Motorsport GmbH or was sent to Osella in Italy or to Ron Dennis in Great Britain to be completed. However, the assembled parts were always selected and provided by those in Munich. The mix of BMW M1 prepared by the factory and those prepared by privateer teams increased the appeal of the one-make cup.
