On 26 November 1968, Auto Union invited dealers and the press to attend the presentation of the newly designed Audi 100 at the Ingolstadt City Theatre.

1967 NSU presents the Ro 80
In September 1967, NSU presented a completely new model in the upper mid-size category, the NSU Ro 80. Its outstanding feature was a 115 bhp twin-rotor rotary piston engine. Its modern body was ahead of its time and featured styling elements that only became the norm in body design several years later. The NSU caused a major sensation, but was unable to help the Wankel principle make the breakthrough hoped for.   View large picture.

1963 The NSU Prinz is the sensation at the IAA
The open-top two-seater on the NSU stand at the 1963 Frankfurt Motor Show was a sensation. Known as the Wankel Spider, this small two-seater had a single-rotor rotary piston engine at the rear. NSU had been working together with Felix Wankel on a new engine concept since the beginning of the 1950s: instead of a reciprocating piston, a rotor compressed the fuel/air mixture (rotary piston engine).   View large picture.

September 1974 saw the launch of the Audi 50, the smallest car in the Audi model range and Audi's answer to the energy crisis of the early 1970s.

Six months after the appearance of the Audi 50, this model was also launched on the market as the VW Polo.   View large picture.
