The Volkswagen Passat is a nameplate of large family cars (D-segment) manufactured and marketed by the German automobile manufacturer Volkswagen since 1973. It has been marketed variously as the Dasher, Santana, Quantum, Magotan, Corsar and Carat, with varying body styles such as saloon, estate, and hatchback.

The Audi 80 is a compact executive car produced by the Audi subdivision of the Volkswagen Group across four generations from 1966 to 1996. It shared its platform with the Volkswagen Passat from 1973 to 1986 and was available as a saloon, and station wagon — the latter marketed by Audi as the Avant. The coupé and convertible models were not badged as members of the range, but used a derivative of the same platforms.
