The Audi Quattro was the first rally car  to take advantage of the then-recently changed rules which allowed the  use of four-wheel drive in competition  racing. It won competition after competition for the next two  years.  To commemorate the success of the original vehicle, all subsequent  Audis with their trademark quattro four wheel drive  system were badged "quattro" with a lower case "q". The original car  with the upper case "Q" in the Quattro name is a collector's piece.
The Audi Quattro shared many components and the core of its body  style with the Audi Coupé, which was a  member of the Audi 80 (B2) model range.  It was internally designated Typ 85, a type number it shared  with the Audi Coupé GT, Audi Coupé quattro and Audi 4000CS quattro. Its characteristic flared  wheelarches were styled by Martin Smith. Audi Quattro had  independent rear suspension and independent front suspension.
