About the Audi A8

The Audi A8 is a full-size luxury saloon manufactured and marketed by the German automaker Audi from 1994 to 2026. Succeeding the Audi V8, and produced through four generations, the A8 has been offered with either front- or permanent all-wheel drive and in short- and long-wheelbase variants. The first two generations employed the Volkswagen Group D platform, with the current generation deriving from the MLB platform. After the original model's 1994 release, Audi released the second generation in late 2002, the third in late 2009, and the fourth and current iteration in 2017.
