1969 Porsche 917K

Taking advantage of an FIA rule change allowing larger engines, Porsche developed a completely new race car: the legendary 917. Constructed of advanced lightweight materials and powered by an air-cooled flat-twelve that generated nearly 600 horsepower, the 917 initially had handling problems due to aerodynamic lift. Changes to the tail designs improved stability and in 1970 a 917K delivered Porsche its first of 19 wins at the 24 Hours of Le Mans.
