In 1975, Chevron was commissioned by David Purley to create a new car for him to race in the European F5000 Championship. Chevron used the 3.4-litre Cosworth GAA V6 engine that had been homologated for Formula 5000. Purley in his Chevron took 2nd place in the first round of the Championship (March 15, Brands Hatch). On the next day the Race of Champions, non-championship Formula One race, was held at Brands Hatch. Organizers decided to top up the grid with Formula 5000 cars. The race was won by Tom Pryce in Shadow DN5, while Purley was 11th, last finisher and only F500 car reached the checkered flag. Later that season Purley won two rounds of the championship (in Brands Hatch and Oulton Park) and was 5th in the final Championship standings. On the next year he used Chevron B30 – Ford in the British F5000 Shellsport International Series, winning the title and 6 out of 13 rounds.
