Although Ferdinand Piëch had left the Porsche company, the final evolution of the 917 was created. Two complete 917/30 Can-Am cars with 2500 mm wheelbase were made and acquired by Roger Penske Enterprises racing team. They were chassis 917/30-002 and 003. The 001 car was not a real 917/30 and was raced in Europe at the Interserie. The Can-Am 917/30 had a flat 5.4-litre 12-cylinder twin-turbo engine which produced so much power that nobody really knew how much. It was the most powerful racing sports car ever created and being so unbeatable, it is known for killing the Can-Am series's popularity. In the 1973 Can-Am series Mark Donohue drove both the chassis 002 and 003. The cars had the same livery and beared the same racing number, so the spectators didn't know which one he drove in which race. Donohue said: “It’s the only car I’ve ever driven that can spin the tires at 200 mph.”
