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.
