On 8 June 1948, the first car to bear the Porsche name was road-certified: the Porsche 356/1 Roadster produced in Gmünd (in Carinthia, Austria). The “Gmünd Roadster” was powered by a 1.1-liter air-cooled flat-four engine from Volkswagen. The engine’s power was increased to 35 hp for the 356. The roadster weighed just 585 kilograms and reached speeds of up to 135 km/h (83 mph).
