1972 Chevron B21 Sport Roadster

Derek Bennett was the founder of Chevron Cars Ltd. He was a brilliant engineer, mostly self-taught, and had a talent for modifying, designing and fabricating race cars. Team Chevron drivers included Jochen Mass, Gerry Birrell, and Peter Gethin. Power was provided by a Cosworth Hart BDA, 2.0 liter DOHC 16-valve four-cylinder engine producing 250 horsepower.

Chevron moved into international competition when the B16 made its inaugural debut at the 1969 Nurburgring 500km driven by Brian Redman. It was Redman who pointed out that with heavy bodywork it would be beaten on most circuits by lighter open-topped Spyders from the marques like Abarth and Lola. The B16 Spyder was introduced in 1970, with a body inspired by the Porsche 908, and this started a long line of successful two-liter sports racers.

This was the last B21 built in 1972, and after racing improvements and modifications became the prototype B23 model. This particular B21 was the Chevron Works entry for the 1972 South African Springbok series. The car competed in all five events in the Springbok series winning four of them on their way to clinching the 1972 championship.
