Audi quattro 20V, 1989
The Audi quattro presented at the Geneva Motor Show in March 1980 represented a quantum leap in the repositioning of the Audi brand. The statement “Vorsprung durch Technik” was taken literally. A new 20-valve engine was introduced in 1989. With it, the quattro became the last series production model to be given a controlled catalytic converter. After 11,452 Audi quattro cars had been built, production of the longest built Audi model ceased on 17 May 1991.
