Ferdinand Porsches engineering background is legend, and after the war a design studio run by his son Ferry designed the 4 wheel drive rear engined supercharged Grand Prix car for the post war Grand Prix era for the Italian Cisitalia. Ferdinad Porsche had no hand in this as he was still interned, but afterwards said there was nothing on the design that he would have done differently - so the capability at Gmund in Austria, was as high as anywhere in the world. After a prototype was sold the ensuing publicity led to orders and some 52 cars were made at Gmund with the 270 employees, before the factory was relocated in Germany in the Reutter bodywork factory, and the 356 model was continually developed until 1965. The 911 model was introduced in 1963. A less expensive 912 was of which nearly 33,000 were sold before it ceased in 1969 when the 914 "Volkswagen-Porsche" was introduced and sold unbelievably well. It's successor in 1976 was the front engined 924 using the 2 litre Audi engine, followed in 1978 by the V8 engined 928.
