The Porsche 917 was designed by chief engineer Hans Mezger under the leadership of Ferdinand Piëch and Helmuth Bott. The car was built around a very light spaceframe chassis (42 kg (93 lb)) which was permanently pressurised with gas to detect cracks in the welded structure.

Power came from a new 4.5-litre air-cooled engine designed by Hans Mezger, which was a combination of 2 of Porsche's 2.25L Flat-6 engines used in previous racing cars.
