The Ford GT40 is a high performance American-British endurance racing car, built and designed in England (Mk I, Mk II, and Mk III) and in the United States (Mk IV), and powered by a series of American-built engines, which won the 24 Hours of Le Mans four consecutive times, from 1966 to 1969 (1966 being the Mk II, 1967 the Mk IV, and 1968-1969 the oldest chassis design, the Mk I), Including a 1-2-3 finish in 1966. In 1966, with Henry Ford II himself in attendance at Le Mans, the Mk II GT40 provided Ford with the first overall Le Mans victory for an American manufacturer and the first victory for an American manufacturer at a major European race since Jimmy Murphy´s triumph with Duesenberg at the 1921 French Grand Prix. The Mk IV GT40 that won LeMans in 1967 is the only car designed and built entirely in the United States to win the overall title.
The GT40 was originally produced to win long-distance sports car races against Ferrari (who won at Le Mans six times in a row from 1960 to 1965). FORD/Shelby Chassis # P-1075, which won in 1968 and 1969, is the first car in Le Mans history to win the race more than once, with the same chassis. Using an American Ford V-8 engine of 289 cubic inch displacement capacity. It was later enlarged to the 302 cubic inch engine,with custom designed alloy Gurney-Weslake cylinder heads. The car was named the GT (for Grand Touring) with the 40 representing its overall height of 40 inches (measured at the windshield) as required by the rules. Large displacement Ford V8 engines were used.
The contemporary Ford GT is a modern homage to the GT40.
