Delecour was then hired by the Ford team to contest the 1991 World Championship. The four-wheel-drive Ford Sierra Cosworth, introduced the previous season, was not regarded as fully competitive, but Delecour demonstrated a remarkable turn of speed on the Monte Carlo Rally. He took the lead from reigning world champion Carlos Sainz on the third day and seemed certain to win until he lost five minutes with suspension failure on the final night and dropped to third place. Delecour retired from the next three events he contested, but then took fourth and third places on the San Remo and Catalunya rallies and sixth on the final round of the series, the RAC Rally in Great Britain, to finish seventh in the driver’s championship. Delecour remained with Ford for the 1992 season, and was joined by twice world champion Massimo Biasion. Results were generally better than in 1991, with second places for Biasion in Portugal and Delecour on the Tour de Corse. Delecour also took third place on the San Remo, leaving him sixth in the World Championship.
