Porsche 935 F6 2100 cc Twin-Turbo
Was not super successfull race car, but definetely was fast one. Don't conuce with 936 model, wintter of LM '77
The successor Porsche 956 was introduced in 1982 after the new 2650 cc engine designed for Indycar was tested in the 1981 winning chassis 003 which was sponsored by Jules, a Christian Dior fragrance for men. At the inaugural year of the new Group C formula which the 956 was built for, privateer teams such as Kremer Racing and Joest Racing had to wait until 1983 for their 956. Thus, in an attempt to conform to the new Group C regulations, both teams built new bodyshapes that incorporated a roof onto their 936-replicas. Joest's car was designated as 936C JR005 while Kremer's car became known as the CK5 01.
