1984 Sthemo SM C2 Sound - BMW M1 ProCar Engine on a Group C Prototype!

This video is about a quite unknown Group C prototype called Sthemo SM which raced in the Group C2 class (also called Group C Junior) during 1984 and 1985. The car is powered by a BMW M88 3.5-litre straight-6 engine which is the exact same engine we can find in the famous BMW M1 ProCar. Listen to that engine screaming around Spa-Francorchams circuit during the 2017 Spa Classic racing weekend!
