Delecour led going into the seventh special stage before his engine began to play up. His Italian team-mate, Biasion, briefly moved to the top of the standings before he, too, was forced out of contention. Their problems cleared the way for the Spaniard Sainz, without a race win this season, to take charge of an event Lancia have won every year since 1985.
However, Sainz has lost the support of his Italian team-mate, Andrea Aghini, who won last year. Aghini dropped out on the opening day of the three-day race with mechanical problems.
The drivers were last night heading for the small Tuscan town of Il Ciocco with the evening stages raced in thick fog.
Toyota have already wrapped up the constructors' championship.
