Porsche 956 B

Chassis 115 is one of only six 956 B-specification cars built by the Porsche factory. The B brought a lighter tub, a redesigned high-downforce nose, a flat underbody feeding the rear venturis and Bosch Motronic fuel injection on the 2.6-litre twin-turbo flat-six. Only 28 956s were made, and the page says this is one of just three surviving B-spec cars with an original, undamaged factory chassis.

Its race record is strong. Run by Kremer in Kenwood livery, it led the 1984 Le Mans 24 Hours for six hours with Vern Schuppan, Alan Jones and Jean-Pierre Jarier, and finished sixth. A fortnight later it won the Norisring 'Money Race' with Manfred Winkelhock. It finished fifth at Le Mans in 1985, then raced in Japan's All-Japan Sports Prototype Championship with Alpha Cubic, taking podiums in 1985 and 1986. The page says it never retired in its three-year career.

Kremer bought it back, and it later passed through Coys to Tony O'Neill and then Henry Pearman's collection in 2004. It has been with the current owner since 2015, who returned it to 1984 Le Mans specification and Kenwood livery. The high-downforce 'Sprint' nose and tail sections are included in the sale. It is eligible for Le Mans Classic and the Peter Auto and Masters Group C series. Price on application.
