The 904, full name Porsche 904 Carrera GTS, was in many ways a special model for Porsche. Due to the unique design of Ferdinand Porsche, the sports car is affectionately called “Butzi’s masterpiece” and is still considered by many to be one of the most beautiful road racing cars. In a record-breaking development period of six months, the Porsche 904 was implemented in 1963. But not only that made this car a model in terms of innovation. For homologation (the approval process) as a race car, about 100 units of the Porsche 904 were registered as road vehicles and sold to private customers. The demand was so great that the car soon became a highly exclusive rarity. The distinctive look that characterises the Porsche design and the combination of technical innovations and low production costs did the rest to give the Porsche 904 a cult status that continues today.
