The sports car Porsche 356 No. 1 Roadster (Sport 356/1) was the first vehicle to be built under the Porsche name , a prototype with a mid-engine and a tubular steel frame . On June 8, 1948, the car received an individual license and was approved for road traffic on June 15, 1948. Series production did not follow.
A small series of the later Porsche 356/2 with its sheet metal chassis and rear engine was in preparation at the time, but no copy was completed by August 1948. As part of the supporting program for the race in Innsbruck on July 11, 1948, the 356/1 was presented next to a Berlin-Rome car . His concept was later adopted for the Porsche 550 .
According to Porsche documents, work on the first sports car with the name Porsche began on July 17, 1947 at the Porsche factory in Gmünd under the direction of Ferdinand "Ferry" Anton Ernst Porsche , which was then transferred in November 1944 under the name Porsche-Konstruktionen-Ges.mbH the design office had been relocated to Stuttgart because of the air raids . The later financing of this project took place from 1949 on from a contract with the then VW general director Heinrich Nordhoff . The agreement guaranteed Ferdinand Porsche a license fee of five marks for each VW Beetle produced (this corresponded to approx. 0.1 percent of the gross sales price), Beetle parts for building his own sports car and selling it through VW dealers. As a result, most of the technical components came from the Beetle.
The chassis of the prototype was a self-made tubular steel space frame with the front and rear axles of the VW Beetle . On this scaffolding, Ferry Porsche had a self-designed body assembled from aluminum sheets that were hand-driven over wooden molds . This body had a drag coefficient of 0.462.
The fan-cooled four-cylinder piston engine with a displacement of 1131 cc, and a capacity of the original 25 hp (18.4 kW) at 3300 / min, the unsynchronized four-speed transmission as well as the axes of VW came. The engine output was increased to 35 hp (26 kW) at 4000 rpm, and the maximum torque increased from 67 Nm at 2000 rpm to 69 Nm at 2600 rpm. This increase in performance was achieved, among other things, by new cylinder heads with V-shaped hanging valves. A further increase to 40 hp was possible with two carburettors instead of just one. The machine was installed lengthways in front of the rear axle .
The ready-to-drive 585 kg roadster reached a speed of 135 km / h or 140 km / h with the front passenger seat covered. As was common at the time, the vehicle had four drum brakes .
When Ferdinand Porsche, after his release from 22 months of French prison , was able to assess the first vehicle with the name Porsche , which had been built at the Porsche factory in Gmünd under the direction of his son Ferry, he found the result to be absolutely satisfactory.
Later the car was sold for 7000 Sfr. sold to the Zurich car dealer Rupprecht von Senger, who bought it for CHF 7,500. resold to the first Porsche customer. Porsche invested the proceeds in the construction of new sports and racing cars .
In 1953 Porsche bought back the 356/1. The vehicle is now in the Porsche Museum in Zuffenhausen .
