The Porsche 917 is a 5 litre sportscar with a minimum of 25 models to be built for homologation reasons according to the FIA regulations at the end of the sixties. The original version of the 917, initiated by Ferdinand Piech and designed by Paul Hensler and Hans Mezger was shown for the first time at the Geneva Motor Show in 1969. It is the fastest series production car of all times, faster than it`s closest rival, the Ferrari 512 from Maranello. The 917 was available in a short back and a long back coupé version. While the sports car versions belonged to Group 5, the PA, Spyder and 917/10 or 917/30 models were made under the Group 7 (two-seater racing cars) regulations. In contrast to Porsche`s series production engines (boxer), all 917 versions were 180° V shape engines - cooled by air as ever.
