The Audi A8 is a four-door, full-size, luxury sedan manufactured and marketed by the German automaker Audi since 1994. Succeeding the Audi V8, and now in its fourth generation, the A8 has been offered with both 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.
