1971 PORSCHE 917K


We are pleased to offer this very unique 1971 Porsche 917K. The car was commissioned by Bill Freeman of Newman Freeman Racing, a race partnership that included the late Paul Newman that successfully competed in various forms of racing, including Indy Cars, Can-Am, S.C.C.A and I.M.S.A racing. Billโ€™s company, Fine Sports Cars specialized in restoring legendary sports racing cars and recreating significant racing cars to very a high level of detail, like this Porsche 917K. This Porsche 917K was Billโ€™s last project and was going to be the only, authentic 917K recreation built. Unfortunately, Bill had passed away before the car could be completed, so we have been asked to sell it. There is very little to complete the car and we are happy to assist any way we can. We have gone through the car and have spoke to the original builder to determine what is left to complete the car and mostly it just consists of finish plumbing the systems (Brakes, Oil & Fuel), exhaust and some wiring. We also have access to the builder, many of the suppliers, as well as the engine tuner that can tune the engine and will be happy to provide those to the new owner.


There are over 3000 hours into this build and Bill and his team went to great lengths to build this car to the 917K specs. They had access to the original cars and were able to get measurements, source original parts, or remanufacture them to make this car as close to the original cars as possible. This includes the entire rear engine section of the car that was unique to the 917K. This also includes a custom made rear suspension and bodywork to allow for the massive rear wheels and tires that were unique to the 917K.

The 917K was further developed for the 1971 season, and the car had vertical fins and two air boxes on the tail section for better aerodynamics and cooling. The fins retained the airflow over the rear part of the bodywork, allowing the deck height to be reduced for a given level of downforce. As a result, the ‘finned’ 1971 917Ks were faster than the 1970 versions and proved just as successful, winning seven of the eleven WSC races. A version of this model with a lightweight magnesium chassis won the 1971 24 Hours of Le Mans. The white #22 Martini Racing entered 917K of Helmut Marko and Gijs van Lennep set an overall distance record that stood until 2010. This Porsche 917K still holds the fastest lap at the Le Mans racing circuit to this day.

The Porsche 917 represents a turning point for motorsport. It marks the transition from a focus on speed to a focus on low lap time through increased downforce and thus corner speed. At the end of the Mulsanne Straight, the 917’s were traveling at 240 mph. The 917 was never designed to be pretty. It was designed to be fast. Its beauty is just a happy corollary.

The ultimate tribute was paid to this successful design when the FIA changed the regulations for the 1972 season, thus precluding the 917’s from competing again. The romantic, high speed era of beautiful cars, which began with the post-war Jaguars, Aston Martin’s, Mercedes, and Ferrari’s, finished, making the Porsche 917 the last icon of this legendary breed.
