Ten years later, Biasion secured the first of those two titles with Lancia. He will drive a 037 this week.
Biasion will be joined by countrymen and fellow rally stars Tony Fassina, Piero Longhi and Gigi Galli. The hugely popular Galli takes his 600bhp Kia Rio RX rallycross car into a stage for the first time.
Hyundai will demonstrate the modern era of the sport, with title-chasing Thierry Neuville driving an i20 wrc. Team-mate Andreas Mikkelsen gets an older-specification i20.
The non-championship event starts with a night time parade through San Marino on Thursday, with the competition running from Friday to Sunday.
