The cream of Ford's efforts came on the race track and drag strip, which lent credence to the premise of their campaign. The Ford GT40 won overall in 24 Hours of Le Mans in 1966, 1967, 1968, and 1969, and chalked up numerous victories in other endurance races such as the 12 Hours of Sebring and 24 Hours of Daytona. Legendary engines, like the big-block Ford 427 engine, and the Ford-sponsored Cosworth DFV were products of this era. Ford engines powered hundreds of victories in Formula One, NASCAR, CART, and other racing series. Ford-powered Lolas raced in the Can-Am series, and other Ford vehicles (most especially the Ford Escort) were successful in rallying.
