Model history

The genesis of this car is legendary. To have Essentially the thought leaders at VW in Wolfsburg, with the 1965 bankruptcy purchased Auto Union threatened another assembly plant for the still well- selling VW Beetle acquired. The spare capacity were filled with the assembly of the VW Beetle, which now rolled off the line in Ingolstadt. So Volkswagen boss Heinrich Nordhoff had decreed that no new Audi models should be developed more. The bad selling DKW F102 was revised and equipped with a four-stroke engine. This referred to as "Audi F103 " car, the Auto Union Audi brand was new.

The coming of Daimler -Benz engineer Ludwig Kraus, however, did not believe in the future of VW Beetle and developed without the knowledge of the parent company and mostly after work a new model under the name Audi 100 until the finished car was Nordhoff finally presented. In the Audi 100 for the first time a computer-calculated body ( finite elements) was developed in the emergence of a series vehicle.

The plan was to produce a one-off print run of 100,000 vehicles, but the demand was so great that by July 1976 the first Audi 100 827 474 vehicles were produced.

The secret development of this model, an unusual in the West German automobile history process was ultimately the reason that Audi was retained as an independent brand at all. Audi's technical know -how (especially after the merger with NSU in 1969 ) saved the early 1970s, fighting with sales problems Volkswagenwerk AG. This had maneuvered with the rear engine monoculture of the beetle and its derivatives up to the VW 411 technically offside and was only by drawing on developments in the Group subsidiary Audi NSU (VW K 70 1970 or Audi 80 1972) capable of their offer convert short time on modern models with water-cooled front engine and front wheel drive.

All of the cars were equipped with four-cylinder engines of 1.6 l and 1.9 l displacement. With the exception of offered as the base engine only from 1974 1600 OHC engine from the new Audi 80 all engines based on the acquired formerly of Mercedes' medium-pressure engine " of the Audi F103, a conventional design with side camshaft and bumpers, although reliable and economical, but also ran rough.

In 1971 the production was moved to Neckarsulm in the former NSU factory. Even before introduced in the series in March 1980 four-wheel drive " quattro " Audi NSU experimented in prototypes of the Audi 100 with a four-wheel steering. This development, however, was discarded and developed only in the late 1980s at Mazda for series production. In contrast to the all-wheel drive, the all-wheel steering has been developed only for the commercial vehicle sector.
