Porsche 909 Bergspyder

Weighing just 384 kilograms including oil and fuel, the 909 Bergspyder is the lightest racing car Porsche has ever built. This vehicle represents the pinnacle and completion of the technical development of Porsche hill-climbing race cars. The thin fibre-glass body weighs ten kilos. Both 909 Bergspyders that are built by Porsche feature aluminium space frames and titanium coil springs. For the short hill-climb sprints, the 909 is fitted with a silver-oxide battery and silver wiring for the electric system. There is no fuel pump for the air-cooled, two-valve engine. Instead fuel comes from a pressurized 15-litre titanium ball. With the differential behind the gearbox, the latter plus the engine and driver move forward, which results in a very favourable weight distribution. Porsche races the 909 only twice in the European Hill Climb Championship late in 1968. After having clinched nine championships in eleven years, the factory then turns its full attention to circuit racing and rallying.
