Inspired by the work and design philosophy of Ferry Porsche, son of founder Ferdinand Porsche, and designed by Wilhelm Hild. The 550 was originally built to compete for Porsche in the roadster racing class. 43 Spyders were built as non-racers, one of which was purchased by James Dean, which is also the one he was driving and he met his tragic end. An engineering leap, the 550 combined a mid-engine layout, ladder framed chassis, and independent body with an extremely low profile and flaring fenders for optimal aerodynamics.
