 Ferrari achieved the 4.5-litre goal of the formula with the 375 F1, two of which debuted at Monza on September 3, 1950.This 4.5-litre (4493.73 cc/274 in³) engine produced roughly the same power as its 4.1-litre predecessor, but its tractability earned Ascari second place in that debut race.A series of modifications through the 1951 season allowed Ferrari to finally put Alfa Romeo behind it in a Formula One race, with José Froilán González' victory at Silverstone on July 14 becoming the constructor's first World Championship win.
