The original Audi Quattro competition car debuted in 1980, first as a development car, and then on a formal basis in the 1980 Janner Rally in Austria.
Largely based on the bodyshell of the road-going Quattro models (in contrast to the forthcoming Group B cars), the engine of the original competition version produced approximately 300 bhp (224 kW; 304 PS).
