Back in the 90s Audi had a decision to make. It was time to retire the Audi 80 so work began on a new model as its successor. The new compact executive vehicle that would take its place was finally presented in 1994, it would be the first of at least five generations which are still in production today. It was a long process that began with sketches and development plans in 1988. Imre Hasanic was chosen to provide the exterior design in 1992 and the interior had been finalized and approved by 1992. Audi is a German car manufacturer which is a subsidiary of the Volkswagen Group. The A4 model received inspiration from the GroupB platform of the Volkswagen. It is worth noting that the Audi A4 vehicles have all retained the internal numbering that picks up where the A80 left off with a clear distinction that it is a continuation of the line in its DNA.
The first generation: 1994-2001
The Audi A4, known in the plant by the Type 8D was first presented to the world in October of 1994 with a teaser reveal that let everyone known what was coming within the next calendar year.
