1971 Emil Stadtmann (Switzerland) - AllCarIndex

In 1963, Zurich-based technical employee and Porsche enthusiast Emil Stadtmann set out to build his own custom sports car. With the help of a colleague, Stadtmann spent over 1,500 hours crafting a unique vehicle from scratch, using plaster to form a mold for the body and later laminating it in polyester fiberglass. Inspired by Porsche’s iconic design, the car was built on a Porsche 356 B chassis, featuring a 1.6-liter, 4-cylinder Porsche engine producing 90 HP.

The car's lightweight construction—just 650 kg—allowed for impressive performance, achieving a top speed of 190 km/h and a power-to-weight ratio of 7.02 kg/HP. Equipped with original Porsche suspension, drum brakes, and ZF steering, the vehicle offered agility and precision on the road.

With a compact, sleek design and a 2+2 seating configuration, Stadtmann’s custom creation was not only a testament to his technical skill but also a tribute to Porsche’s engineering. His handcrafted sports coupe remains a unique symbol of passion, creativity, and personal craftsmanship in automotive history.
