The original Ford Mustang was a 2-passenger concept car often referred to as the Mustang I. An almost purist sports/racing machine it had full 4-wheel independent suspension and a mid-mounted V-4 engine. Although it contributed little more than its name and the galloping horse emblem to the production Mustang it was a step in the path that led to the development of one of the most successful racing cars of all time, the Ford GT-40. Today the Mustang I is housed in the Henry Ford Museum at Dearborn, Michigan.
