The Audi Avantissimo was a concept car by the German automobile manufacturer Audi. The Audi Avantissimo debuted at the 2001 Frankfurt Motor Show in Germany. It also appeared at the 2002 North American International Auto Show in Detroit. Audi planned the Avantissimo to be luxurious and distinguished, but very swift at the same time. Many of its styling cues are visible on the 2004 Audi A8.
