Giuseppe Farina
Fangio had no compunction about leaving a team, even after a successful year or even during a season, if he thought he would have a better chance with a better car. As was then common, several of his race results were shared with teammates after he took over their car during races when his own had technical problems. His rivals included Alberto Ascari, Giuseppe Farina and Stirling Moss. Throughout his career, Fangio was backed by funding from the Argentine government of Juan Perón.
