Few auto racing efforts were as ambitious as Ford’s quest to beat Ferrari at the 24 Hours of Le Mans, the world’s most important sports car race, in the 1960s. Ford’s dedication paid off, first in 1966 when GT40s finished 1-2-3 at the French endurance race, and then again in 1967 with an all-American victory by drivers Dan Gurney and A.J. Foyt in the Ford Mark IV. Fifty years later, we look at the Mark IV – and Ford’s long road to glory at Le Mans.
