Engine makers

According to MSHFA rules, foreigners should be considered only for achievements in American motorsports, but even if you discount the impact of their game-changing DFV F1 engine, introduced in 1967, the Britons behind Cosworth Engineering had immense impact here in the U.S. In the mid-1970s the Cosworth DFX — a turbocharged short-stroke evolution of the DFV — became the go-to engine in IndyCar racing, ending decades of Offenhauser dominance. From 1978 to 1987 the DFX took 10 consecutive Indy 500 victories. The Cosworth XB added two more 500 victories in 1995 and ’96. Overall, Cosworth engines scored more than 200 IndyCar wins and 11 drivers’ championships for inductees like A.J. Foyt, Al Unser, Johnny Rutherford, Nigel Mansell, Rick Mears, Tom Sneva, Bobby Rahal and Michael and Mario Andretti. Other Cosworth engines were mainstays in SCCA Formula B and C and the Formula Atlantic series. And the DFV powered Andretti to his 1978 F1 World title and Harley Cluxton’s Mirage M8s to consecutive second-place finishes at the 24 Hours of Le Mans (1976-7).
