16. Ford GT40
Every Ford GT 40 was an utter surprise to the motoring world. But the first one they introduced in late 1965 was the biggest. Ford was always an economy manufacturer with a wide range of affordable cars and trucks. However, never has a company like that built a world-class supercar capable of beating all those European exotics.
In fact, it won the 24 Hours of Le Mans race four times in a row. But that is exactly what Ford did and what made the GT40 such a legendary and important car.
