The BMW M1 is a special machine. Sure, by today’s standards its performance is somewhat pedestrian, but back in the 1970s, when the M1 was first released, it was the real deal. BMW even set up a one-make ‘M1 Procar’ series.

The category supported Formula One races in Europe for the 1979 and 1980 seasons. Better than that, the first five F1 drivers from Friday practice were all given a factory-backed M1 Procar to race on Saturday. Those were the days!

Well, luckily for us those days have been given a revival of sorts thanks to this new onboard video of an M1 Procar being driven around the famed Nürburgring Nordschleife earlier this month. Klaus Graf is the man at the wheel, fresh from his recent win at the Road Atlanta ALMS race.

Apparently this was his first flying lap in the M1 Procar at the ‘Green Hell’ so posting a sub-8 minute lap time is not too shabby at all. Perhaps this should come as no surprise. After all, the very same car was driven by Nelson Piquet and Hans-Joachim Stuck to third place in the 1980 Nürburgring 1000km race. But, most all, we love the noise. Oh the noise!

A big thank you to frozenspeed for making the clip available (check it out below). There’s also a couple of bonus M1 videos for you to enjoy.
