This 1970 Porsche 917/10 Prototype, chassis number 917/10-001, is the first 917 Can Am Spyder and the only 917 of all variants with chassis number ‘001’ in private ownership. It has a notable competition history, only four private owners from new, and is comprehensively documented. The car features a 600+ bhp, 4,998 cc DOHC air-cooled horizontally opposed 12-cylinder engine with Bosch mechanical fuel injection and has undergone a full restoration, presented as a ‘point-in-time’ restoration replicating its 1971 Weissach wind tunnel configuration.
