Steve McQueen drove a Porsche 917 in the film Le Mans, and while that alone is reason enough to put this car on the list of the greatest Porsches of all time, the 917 itself has the goods to solidify its place as one of the greatest race cars of all time. Powered by a flat-12 engine capable of over 620 horsepower, the Porsche 917 was hellishly fast. Flying under the Porsche/Gulf Racing banner, the 917 gave Porsche its first overall win at the 24 Hours of Le Mans in 1970, a feat it repeated the following year. Porsche officially retired the car in 1971, but the car would go on to conquer racetracks around the world for another 10 years.
