to enter the 24 Hours of Le Mans with modified 924s, which had no hopes of winning. This didn't sit well with Porsche's new CEO Peter Schutz, who insisted that Porsche enter with a car capable of winning or not at all. Porsche engineer Peter Falk suggested an Indy engine developed but never used due to new US regulations, which would have made it uncompetitive for the Indy series, however, it could have been competitive in a sports car chassis, so it was approved by Porsche's engineering chief Helmuth Bott, also it provided an opportunity to test the engine for the 956. So a few 936s were pulled out of the Porsche museum in Stuttgart, redesigned to create the 936/81 and entered as 2 official works entries for the 1981 Le Mans 24 Hours. Jacky Ickx was coaxed out of retirement, and at the Belgian's request got Briton Derek Bell as his teammate for the race, which they then won, with the Mass/Barth/Haywood sister car retiring. Porsche engineers provided some unofficial support to very good customers, though, and Joest managed to get a spare chassis (004) and parts to assemble a car which was in 1980 designated as Porsche 908/80 and entered privately by Joest Racing. The Martini Racing Liqui Moly backed car took second at Le Mans in 1980. Kremer received blueprints to recreate a modified '81-spec car dubbed chassis 005 for 1982. 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.
