The Chaparral 2F is a Group 6 sports prototype designed by Jim Hall and Hap Sharp, and built under their company Chaparral Cars. Built with the intention to compete in the World Sportscar Championship, it competed in the 1967 season, with a best finish of first at the BOAC 500, driven by Phil Hill and Mike Spence. The 2F, alongside its predecessor the 2E, had a heavy influence in dictating the direction of Formula One car design in the late 1960s and early 1970s, with a larger emphasis on aerodynamic efficiency.
