Last weekend’s presentation of the BMW M1 Homage Concept (see here) prompted us to perform a search on the original M1’s history and in particular, its racing heritage. Our hunt led us to the discovery of two, nostalgic late-1970’s videos of the M1 Procar racing version, one from the Procar Series in The peppy M1 Procar edition featured among other things, a modified version of the M88 6-cylinder unit with new camshafts, larger valves, forged pistons, optimized flow ducts, slides instead of throttle butterflies and a modified exhaust system boosting, all of which helped boost output to 470–490 Hp. Weighing in at a mere 1,020 kg or 2,248 lbs, the M1 Procar had a top speed of approximately 310 km/h (192 mph). –Video after the jump
