1973 Chevron B25 F2
Chevron B25 chassis B25/73/7 was constructed at the factory in 1973 as a works Formula 2 entry, powered by a Ford-backed Brian Hart engine and driven by Peter Gethin and John Watson in that year's European F2 Championship. Factory support was curtailed following a fatal accident in the companion car, after which the car was campaigned more modestly before passing to hillclimb competitors Reg Phillips and John Stewart. Following a heavy accident and years of obscurity, the tub was rediscovered in the early 1990s and eventually acquired by Simon Hadfield Motorsport, who began a full restoration. The current owner completed this work and has used the car in several historic events, most recently finishing second at the 2021 Oulton Park Gold Cup. It holds FIA HTP papers valid to 2033.
