In 1953 the famous NSU Max followed, a 250 cc motorbike with a unique overhead camdrive with connecting rods. All these new models had a very innovative monocoque frame of pressed steel and a central rear suspension unit. Albert Roder, the genius chief engineer behind the success story, made it possible that in 1955 NSU became the biggest motorcycle producer in the world. NSU also holds 4 world records for speed: 1951, 1953, 1954 and 1955. In 1956 Wilhelm Herz started at the Bonneville Salt Flats, Utah. Herz was the first man to drive faster than 200 miles per hour, in August 1956. [dubious – discuss] In 1957 NSU re-entered the car market with the new NSU Prinz, a small car with a doubled NSU Max engine, an air cooled two-cylinder engine of 600 cc and 20 hp. Motorbike production continued until 1968.

In 1964 NSU offered the first Wankel engine car of the world: the NSU Wankelspider. In the same year Prinz 1000 and derivates like the TT and TT/S followed. As a family car the Typ 110 (later 1200SC called) was launched in 1965 with a more spacious body design. The last NSU cars with a conventional 4 - stroke engine had the air cooled OHC four cylinder engine in common. In 1968 the sensational 2 rotor 115hp NSU Ro 80 was presented to public and soon gained several design awards like "car of the year 1968". The sensation was never found back in sales figures.
