Porsche 904 Bergspyder

For the underpinnings of the new 904 Bergspyder, the Porsche engineers recycled five chassis originally laid down for a production version of the six-cylinder 904/6 Coupes. The steel platform chassis of the 904 was reinforced with cross-braces to compensate for the rigidity that had originally been provided by the coupe body. The Bergspyders were tried with both the exotic twin-cam eight-cylinder engine and a highly tuned flat six.
