Much alike the rallye Quattro A2, besides the shortened chassis and the new 20 valved engine. First used at Corsica 1984 and last at Ivory Coast rally in 1985, the rallye Sport Quattro had the same displacement as the A2 with 2110cc. It featured approx 400hp by 7500 rpms and 460Nm, with a compression-ratio of 7:1.

0-100 km/h in 4.4 seconds, weight was 1060kg.
Length/height/widht 4239/1859/1343mm.

The rallye version of the Sport Quattro didn’t prove itself highly competitive in the result lists. Stig Blomqvist managed to claim the championship title in 1984, a year he clung to the preferred Quattro A2, when he took the overall win of Côte d’Ivoire (Ivory Coast) rallye.
