In 1967 and 1968, Porsche’s lightweight 910 Bergspyder (the 910 was essentially an updated 906) were the championship-winning race cars. With between 200 and 270 horsepower and weight around 420 kg, they were extremely nimble and well-suited to dominating mountain roads. In 1967 and 1968, the Porsche 910/8 Bergspyder was the dominant force before the 909 came along.
Technically, the Porsche 910 Bergspyder was state-of-the-art, featuring materials such as titanium (brake calipers), beryllium (brake discs), magnesium (wheels), electron (tank), plastic (body) and aluminium. The running gear was similar to that of a Formula 1 car, including an eight-cylinder boxer engine that had about 275 horsepower.
