In addition to the Manufacturers World Championship for production race cars (Group 5, Porsche 935), in 1976 Porsche took part in the World Championship for sports cars (Group 6). In record time, Weissach developed a new racing sports car of the 936 type. Technically, the engineers utilized the proven 908/03 and 917/10 designs in the development of the open Spyder. The result was an aluminium space frame which was covered by a plastic body. Powering the 936 was the 2.1-litre six-cylinder boxer turbo engine with an output of around 520 hp, previously planted in the 911 Carrera RSR Turbo 2.1. See all of our Porsche 936 Research.
