The endurance racing had two world championships: the 1976 FIA World Championship for Makes for Group 5 special production cars, and the 1976 World Sportscar Championship season for Group 6 prototypes up to 3.0L. Accordingly, the 935 and the new Porsche 936 were the two-pronged Porsche effort for 1976 which was sponsored by Martini Racing, which had already supported Porsche 917 or 908 entries in 1970 and 1971, like the 1971 Le Mans winner.
The Porsche 935 Chassis no. 930 990 0029 sold new to Ted Field’s Interscope team, chassis 930 990 0029 made its competition debut at the 1979 Daytona 24 Hours. For the occasion Field was joined by Danny Ongais and Hurley Haywood. Starting from 8th, the ‘0’ car took a brilliant debut victory.
Kremer Racing 935 K1
The Kremer Racing built a 935 K1, and in 1977, modified their customer 935 to the K2. For 1979, they introduced the 935 K3 (for Kremer Type 3; the derivative of the successful K2). Driven mainly by Klaus Ludwig, it won the 24 Hours of Le Mans in 1979, beating all prototypes, in heavy rain, which is usually considered a disadvantage for race cars with windshields. Coming in second was a factory spec model, driven by Rolf Stommelen, and supported by team owner Dick Barbour and actor Paul Newman.
