The Porsche 550 was a racing sports car produced by Porsche from 1953-1956.
Inspired by the Porsche 356, the factory decided to build a car designed for use in auto racing. The model Porsche 550 Spyder was introduced at the 1953 Paris Auto Show. The 550 was very low to the ground, in order to be efficient for racing.
The later 1956 evolution version of the model, the 550A, which had a lighter and more rigid spaceframe chassis, gave Porsche its first overall win in a major sports car racing event, the 1956 Targa Florio.
