Iconic Porsche 550 RS Spyder Hits the Market
One of the last Porsche 550 RS Spyders produced, out of a total of 90
The Porsche 550 was Porsche’s first production racing car. The car was completely street legal, so it could be driven to the races and back home. A really special engine was developed for it, engineered by Ernst Fuhrmann. It was a flat DOHC engine, meaning it had 4 overhead camshafts like the Porsche type 360 design for Formula 1. Although with just 4 cylinders, the engine was really complicated and took a lot of time to build. Compared to the “regular” 1500 cc engine in the 356, the Fuhrmann 1500 didn’t have anything in common with it. The 4-cam Porsche engine developed twice the power compared to the single-cam unit based on the pre-war Volkswagen design (which was also a Porsche design). In all, 90 Porsche 550 cars were built, including 15 prototypes. The 1956 version of the Porsche 550 was known as the 550A. It had a lighter and more rigid spaceframe chassis, and gave Porsche its first overall win in a major sports car racing event, the 1956 Targa Florio. 40 units were made.
