Earlier this month, at the Dix Mille Tours, two very rare Porsches made their first competitive appearance in many years. Undoubtedly the rarest of these was this 917/10, which is one of just 13 built for the Can-Am and Interserie championships during the early 1970s. Based on the all-conquering 917 Group 5 sports cars, these mighty machines were initially available with a naturally aspirated engine, while a turbocharged version would later also be used. The three 917/10s featured today are all fitted with the naturally aspirated version of the engine and were raced extensively in period on both sides of the Atlantic.
Of a slightly earlier vintage was the Porsche 908 Langheck brought by the same collector. Built early in 1968, the car that raced at the Dix Mille Tours was one of the earliest of these three-litre machines. In its original guise, it was not particularly loved by the drivers as it was unstable at high speeds. The car was rebuilt with a later body that used ingenious, suspension actuated flaps on the tail to provide more stability. While the later versions won at Spa and Monza in 1969, the 908 Langhecks' most famous outing came at Le Mans in 1969 where one came within a few metres of clinching the outright victory in what was the closest non-staged victory in the event's history. In addition to the chassis in action at Paul Ricard, our 34-shot gallery also includes images of two additional cars, both still owned by Porsche.
