The Porsche 935 was the Stuttgart manufacturer’s answer to the FIA’s Group 5 class regulations, making it eligible for the World Championship of Makes. The first Porsche car in this so-called ‘Silhouette’ series, was introduced for the start of the 1976 season. The factory entered 935s in both the World Championship of Makes and the World Sportscar Championship, winning both titles, the latter with almost three times the number of points as the second-placed manufacturer.
The factory 935/77 cars featured a twin turbo setup and boasted an extra 40 bhp, now up at 630 bhp. At the end of the 1977 season, Porsche decided to withdraw from the World Championship of Makes and to let its strong and capable band of privateer teams carry the company flag. The factory made one exception in ’78, and that was to run their very special 935/78 ‘Moby Dick’ in the Le Mans 24 Hours that year.
In 1977, Porsche built and sold a small number of 935s to private teams, such as the Kremer Brothers and Georg Loos, these being similar to the 1976 cars. While the Georg Loos cars were essentially factory maintained, the Kremer Brothers did a lot of their own modifications, and became very successful in the process. In 1976, Kremer built the 935 K1, in 1977 they developed the K2, and the K3 was introduced at the start of the 1979 season. The 935 Kremer K3 went on to win the 1979 Le Mans 24 Hours, with a factory-specification Porsche 935 finishing second.
