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.
In North America and Australia, the 80 was marketed as the Audi Fox for model years 1973–79, and as the Audi 4000 for model years 1980–87 in the US. The Audi 90 was an upmarket version of the Audi 80, although all North American sedans of the B4 generation were called Audi 90.
Under Audi's platform numbering convention, the 80 is classified as a member of the B-series or B platform family of vehicles, with the four generations of 80 being numbered as B1, B2, B3 and B4; its replacement – the Audi A4 – continues this sequence with platform numbers B5 through to B9. Originally this numbering convention ran concurrently with that of the Volkswagen Passat, the first generation of which was essentially a badge engineered clone of the Audi 80. This link was severed in 1988 when the Passat moved to a non-related, transverse-engined, VW-specific platform for its 80-unrelated B3 and B4 versions. The Passat was based again on the Audi A4 (B5 or "8D" platform) for its B5 generation, and returned to a transverse engine for the B6 and later generations.
Audi F103
The Audi F103 series, based on the DKW F102 but with an all-new range of four-stroke engines developed in conjunction with Daimler-Benz, was sold between 1965 and 1972. It comprised several models named for their horsepower ratings. From 1966 to 1969 this series included an Audi 80, and there were also Audi 60, 72, 75, and Super 90 models available over the years.
This model debuted in Europe in 1972 as the Audi 80, and in 1973 in Australia and North America (Canada and the USA) as the Audi Fox, and was available as either a two-door or a four-door saloon (sedan).
