Sergio Cresto
Sergio Cresto (January 19, 1956 – May 2, 1986) was the American co-driver of Finnish Henri Toivonen at the Lancia Martini team for the 1986 World Rally Championship season. He was also a former co-driver for fellow Lancia employee Attilio Bettega, who died in an accident during the 1985 Tour de Corse on May 2, 1985. His co-driver Maurizio Perissinot survived the crash uninjured. This event happened exactly one year before the accident that claimed the lives of both Sergio Cresto and his then co-driver Henri Toivonen on May 2, 1986.
