1978 Le Mans 24h, Porsche 934. Everybody knows the famous orange livery of German liquor producer Jägermeister. Interesting is that no cars in that livery drove at Le Mans before, most were racing in ETCC / DRM / DTM and world championship sports cars. One man managed to drive the famous colours at Le Mans: Hervé Poulain, the same that took the initiative for the famous BMW Art cars in the previous years. Again, he added another famous livery to the Le Mans history.

Kremer Porsche 935
1976 Nürburgring 1000 km, Porsche 935 K1. The new group 5 rules were a perfect match for Porsche.

Kremer Racing built its own version of a Porsche 935, the K1. It wasn’t as fast as the works car, but better than the 934/5. Unfortunately the 2nd spot on the grid didn’t pay off in the race because the car retired with a broken driveshaft.

1979 DRM Championship, Porsche 935 K3. The K3 version of the Porsche 935 was a fantastic car. Not only did Klaus Ludwig win 10 out of 11 races in this year’s DRM he would also win Le Mans The following year everybody wanted a K3, but it never came to the succes it had in 1979.
