The 1991 World Rally Championship season was an opportunity for Ford to push for victory again, and to evolve the Sierra RS Cosworth 4x4; lessons learned on the stages would be used to simultaneously develop the Ford Escort RS Cosworth. The cars were again predominantly blue with title sponsorship from Q8, but now featured extra sponsors like Autoglass and Noberasco, which were displayed in white sections on the bonnet and rear flanks of the car. British driver Malcolm Wilson returned, and was joined by a relatively unknown French driver called Francois Delecour. Both drivers were entered on six of the European rounds of the Championship, with Delecour also entering the Catalonia Rally in Spain. A third car was shared by Alessandro Fiorio and Gwyndaf Evans, and a single car was made available for Ari Vatanen at Rally Finland.
