The Audi A6 has been in production since 1994, when it replaced the Audi 100. Originally, it used the same chassis, but it was renamed to fit better into Audi's naming conventions. Audi offered saloon and Avant models right from the beginning and has taken the A6 through five generations, with regular facelifts that keep the lineup fresh and modern.
