sucksqueezebangblow: Porsche 909 'Bergspyder'

One of Porsche's more brutal competition efforts, the 909 'Bergspyder' is as hardcore as they come. Powered by a 2.0-litre eight-cylinder boxer that produced around 300bhp, the car tipped the scales at just 385kg; it was effectively an aerodynamic soap-box racer with a huge sting in the tail.
