The NSU Prinz was manufactured in West Germany by NSU Motorenwerke AG between 1958 and 1973. The Prinz 4 was unveiled at the Frankfurt Motor Show in 1961, when production began, which lasted until 1973. It was sold as a 2-door sedan.

The body of the car was very similar to the then fashionable Chevrolet Corvair, but it was significantly smaller. It was powered by a 0.6-litre, air-cooled 2-cylinder in-line engine, which was mated to a 4-speed manual gearbox. The car was able to reach a top speed of 113 km/h and accelerate from 0 to 97 km/h in 35.7 seconds.
