Weissach, 1965. In this scene a 911 is undergoing suspension testing at Porsche’s now-famous search and development track. After years of trying to test cars on the public highway, in 1960, Porsche had bought a tract of land lying just west of the rural town of Weissach to create its own proving facility. After the earthmovers had smoothed out some of the terrain, the first task was the skid pan because Ferry had learned from Zora Arkus-Duntov, Chevrolet engineer and sometime Porsche works driver, that a skid pan was indispensable. Helmuth Bott, then chief development engineer, architected a 3km circuit around the natural bowl of the landscape. Within this, inner circuits, test hills and handling loops were steadily constructed.
