[1] He was later drafted in to play a key role for the works Lancia World Rally Championship team in the mid-1980s as the squad sought to regroup after previous star driver Henri Toivonen's fatal crash, and would go on to dominate early Group A rallying, taking the world championship in the years 1988 and 1989.

He failed to win an event for Lancia in 1991, and switched to Ford for 1992 on a contract that made him the highest-paid driver of his day, and gave him some managerial input.

The following year, driving the new Ford Escort RS Cosworth, he won the Acropolis Rally and led the driver's championship for part of the season.

Throughout Biasion's tenure at Ford he was overshadowed by the younger François Delecour, who generally proved to be faster, especially on tarmac.

Insufficient resources meant that development of the Escort slipped behind its rivals, and Biasion's relationship with the team worsened as the season progressed.

In 2007, he was part of the manufacturer Fiat team, running the diminutive Panda 4x4 ('PanDakar') on the event, alongside team-mate Bruno Saby.
