In 1984, the long-awaited double success was achieved: Blomqvist took the driver’s title almost unchallenged, with wins in five rallies. The season had already begun with a sensational 1-2-3 victory in Monte Carlo, with Walter Röhrl, a newcomer to the team, leading his Scandinavian colleagues across the finishing line after a breathtaking duel.
During the season, however, the initially unrivalled quattro began to encounter new and vigorous competitors, for example the Peugeot 205 T 16, the first pure competition car concept with mid-engine to be seen in rallying. The temptation for Audi to pursue a similar approach was great, and a prototype was in fact built. The idea was none the less rejected because it was felt that the rally cars should not be too dissimilar to those sold to the public.
Instead of this, the Sport quattro, a 331 kW (450 bhp) front-engined car, made its debut at the end of 1984. The wheelbase was shortened dramatically, by no fewer than 32 cm, in an attempt to make the car even lighter and more agile.
