Porsche 550

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.

Porsche 550A RS Spyder (1956 – 1957)

The 550A was based on Porsche’s first purpose-built racing car, the mid-engined RS 550 Spyder. Appearing at the end of 1956, the 550A differed from its predecessor by use of a full tube spaceframe with several rear supportive cross-members, rather than the heavier welded-up sheet steel internal structure of the 550. The rear swing axles of the 550 were replaced by a new low-pivot arrangement that made handling much more predictable.

Porsche 550 RS Spyder (1954 – 1956)

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.

Porsche 550 Prototype Spyder (1953)

In 1953 Porsche created a series of 550 prototypes and 550-03 became the most important car in Porsche history by winning the 1954 Carrera Panamerica with Hans Herrmann at the wheel. This singular victory lent the Carrera nameplate to future models and also marked the first international victory of a mid-engine car. Only 15 prototypes were made until regular production began in 1954 of the Porsche RS Spyder.

Porsche 550 Prototype Coupé (1953)

One year before Porsche started production of the legendary RS Spyder, they experimented several unique 550 Prototypes. Two of these were fitted with removable hardtops that transformed the diminutive roadster into a sleek coupe. These were quite successful on faster circuits, but the roadster was later preferred as a more saleable car. The Coupes were retained by the factory to contest the Carrera Panamericana race.
