1975 Chevron B31

The Chevron B31/75/05 is the fifth of six examples built in 1975, designed for the European 2-Litre Championship and based on the aluminium monocoque architecture shared with the B26. Powered by an Anderson Racing Hart 420R engine mated to a J&P Hewland FG400 transaxle, it has competed in HSCC historic racing continuously for close to three decades, winning the 2013 HSCC Martini Sportscars Trophy with four victories from eleven rounds. Presented in Martini livery, both the engine and gearbox have been rebuilt, and the car retains valid HSCC and FIA documentation.
