The B40 was Chevron's design for the 1977 F2 season and was a tidied up and improved version of the B35. It was a front runner in the European Championship, wholly competitive with its rivals: the March 772, Martini MK22 and the Ralt RT1. Although the B40 only won twice, Rosberg at Enna and Leoni in the Ferrari-engined chassis at Misano, it was competitive everywhere as five second places showed. In addition to the aforementioned Ferrari engine both Hart and BMW were the engines of choice.
