The M88 engine was also tuned up to 490hp, it weighed just 2,250 lbs. and with long gear ratios top speed was set at 193 mph. Marc Surer, the former Swiss F1 driver, lapped the Nordschleife of the Nurburgring
in just 7 minutes 55.9 seconds. The M1 was sold for 100,000 Deutsche Marks (more than $500,000 today), quite expensive for a BMW. However, the demand was much higher than the supply and all cars were sold before production ceased. When the time arrived for the M1 to take part in Group 4 racing, after it reached the 400 units production milestone, it was already too late.
