For 1993 the Sierra was replaced by the smaller and more agile Ford Escort RS Cosworth. Delecour immediately showed its potential by leading the Monte Carlo until the final night, with Biasion second. However, both lost out to a final-night charge by Didier Auriol, and finished second and third. Delecour at this time was still regarded as a specialist on asphalt rallies, but he finally established his reputation as an effective driver on all surfaces by winning the third round of the series, the Portuguese Rally, again with Biasion second. He won again in Corsica, giving him the championship lead. However, retirement in Greece and San Remo saw the title pass to Juha Kankkunen, although Delecour compensated somewhat by winning the Catalunya Rally and finishing a strong fourth on the RAC, giving him second place in the World Championship. His co-driver, Daniel Grataloup, was awarded the co-driver’s championship for that year.
