Porsche 909 Bergspyder

The Porsche 909 Bergspyder was a spyder sports car that Porsche designed and built in 1968 to compete in hillclimbing, in the Sports Car class of the European Hillclimb Championship. It was short-lived, but its structure, technical innovations and design became the basis of the successful 908/3. Ferdinand Piech and his engineers built it in a hurry to counter the Ferrari 212 E Montagna. Its 2.0 litre, 275 horsepower Type 771 flat-eight came from Porsche Formula 1 work, its fiberglass body weighed just 10 kg, and a pressurized titanium ball fed the fuel in place of a pump to save weight. Rolf Stommelen placed second and third in two races, though the car was a handful to drive and had reliability problems.
