In September of 1959 Porsche revealed their fully updated 356 known as the 356B. This had a completely revised body that was more suitable for the American market. New to the model was the Type 616/7 Super 90 engine which was an indirect replacement for the Carrera de Luxe models. The engine was fully revised with a new intake manifold, a larger Solex 40 PII-4 carburetor and the Carrera air filters.
