The NSU Prinz 1000 was introduced in 1963. It was an important evolution of the Prinz, with a 996cc 4-cylinder engine. With this version, NSU began to position itself in the compact sports car segment. Later the TT version was introduced, also as a rear wheel drive 2-door coupe with manual transmission. This improved sports model used the same 996cc engine but was tuned to produce up to 55hp, making it more popular in touring racing. It was differentiated by its wheels and some aesthetic details. The NSU Prinz 1000 was produced until 1972.
