Born in Turin, and nicknamed "__", X was a doctor of engineering and nephew of Pinin _____ of the coach building company. He began his motor racing career in hillclimbs, graduating to circuit racing with Maserati. But it was not until he moved to Alfa Romeo, as number two driver to Tazio Nuvolari, that his racing career really blossomed. During the late 1930s he won numerous minor races in the Voiturette class, securing himself the Italian Drivers' Champion three years in a row (1937–1939). He then went on to take his first major race win, at the 1940 Tripoli GP. Sadly for _X_, he was just reaching his peak as a driver at the outbreak of World War II, and it would be another eight years before he would win a major race.
Entering post-war Grands Prix in a privately owned Maserati, __X__ took a win at the 1948 Monaco GP. When the FIA announced the inaugural World Championship for 1950, __X___ secured a drive alongside Juan Fangio and countryman Kuigi Fagioli at the dominant Alfa Romeo team, driving the invincible 158 Alfetta cars. __X____ took 3 wins from the 7 races of the 1950 season, securing himself the first ever World Championship. It was the pinnacle of his career.
