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 competion 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" and in a distinct typeface which has remained nearly unchanged since its inception.
The Audi Quattro was made for 11 years, from 1980 to 1991.
