The Chevron B34 was racecar built by Chevron Cars.

The B34 was designed in 1975 as a Formula Atlantic race car. It was then decided to convert the car to a Formula 3 Championship car in the winter of 1975. The first runs in the test car were successful, and Derek Bennett helped to develop the racecar further. In contrast to Formula Atlantic, the car had an engine from Toyota.

The B34 was one of the best selling Chevron racing cars ever.
