When Porsche went to Le Mans, they reverted to aluminum shells made at their first factory in Gmünd, Austria. Three of these coupes, called 356 SL, raced Le Mans. All three Le Mans cars were shipped to America by Max Hoffman and sold to Fritz Kosler, Ed Trego and John von Neumann for SCCA racing. Before the 1952 races at Torrey Pines, von Neumann had Emil Diedt remove the coupe's roof, creating in effect the first Carrera Speedster.
