In the world of racing, the Porsche 917 is known throughout as one of the greatest racing cars of all time. Development of the vehicle began as early as 1968 with their eye on prize: winning the 24 Hours of Le Mans in May of 1970. And while it took them an extra year to reach that goal, the Porsche 917 not only won the 1971 Le Mans but set a distance record that would hold for the next 40 years.
Now, what we have here is an early prototype for this record-breaking race car, known as the Porsche 917/10 variant. It was finalized on December 3rd, 1970 and was used for further research and development before Porsche retired the vehicle. Today, it remains the first of only thirteen builds ever created and the only one in private ownership. The Prototype houses a monstrous 4,998 cc DOHC air-cooled horizontally opposed 12-cylinder engine with a Bosch mechanical fuel injection pushing out over 600 bhp. Front and rear ventilated disc brakes, a front and rear independent suspension, and five-speed manual transaxle are also featured with this one. It’s slated for auction next month through RM Sotheby’s and boasts an estimated value of $5,863,525.
