The F.2 Drivers' Championship was established in 1948. The regulations provided for a series of races on circuits all over Europe and allowed the registration of single-seaters with 2-liter aspirated or supercharged 500cc engines. The new Ferrari for this category (166 F2) was designed around the 1995cc engine that already equipped the 166 with covered wheels. After an uncertain start to the season, the 166 F2s won the races in Rome, Naples, Bari, Monza and Reims. Among the cars there was a blue one with a yellow hood, lined up by the A.C. Argntina for a young driver: Juan Manuel Fangio, who was first in Monza.
