The debut of the 125 F.1 took place at the Valentino GP in 1948, with decidedly good results, which encouraged Enzo Ferrari to continue with the single-seaters too. In 1949 and 1950 the 125 F.1 was further modified and refined, with the adoption of a double-stage compressor and a new bodywork
With the 1.5-litre 125 V12 with supercharger, Alberto Ascari took part in two GPs in the 1950 F.1 world championship season. In Monaco, the Italian driver qualified in seventh place, finishing second.
