During the mid-1960s Porsche decided that if it was to enjoy outright success at Le Mans (rather than class wins) it would need a car somewhat larger and more powerful than those it already had. It was time for something completely different. It was time for the Type 917. Mid-engined like so many earlier Porsches, it had a 12-cylinder air-cooled boxer engine that produced 580 bhp from 4.5 liters when first announced in 1969. After a period of « development » in 1970, the 917 became almost unbeatable, winning at Le Mans and virtually every other circuit. By 1972 the 917 was enjoying success in the hugely popular Can-Am series in America with a turbocharged 5.0 liter engine of 950 bhp and later a 5.4 liter unit that produced over 1,000 bhp! The hero driver was usually the late Mark Donohue. Later came the 935, 956, and the evergreen 962 that enjoyed a race-winning life of many years, way beyond the normal two or three years.
