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 12 prototypes were made until regular production began in 1954 of the Porsche RS Spyder. Of these, Porsche historian Steve Heinrichs believes nine cars currently survive.
