Varzi won six Grand Prix in 1934 driving the Alfa Romeo P3, at Alessandria, Tripoli, Targa Florio, Penya Rhin at Barcelona, Coppa Ciano and Nice.

Quickly overshadowed by teammate Bernd Rosemeyer, his trips to the winners circle dropped to only four, but he did win his third Tripoli Grand Prix in his third different vehicle.

During practice runs for the 1948 Swiss Grand Prix a light rain fell on the Bremgarten track in Berne, Switzerland.

Varzi's death resulted in the FIA mandating the wearing of crash helmets for racing, which had been optional previously.

The team entered some Formula One races in 1950 equipped with Maseratis 4CL and 4CLT and featured drivers José Froilán González, Antonio Branca, Alfredo Pián and Nello Pagani.

In the film, at least twice, Enzo Ferrari said that the newest addition to his racing team, Alfonso de Portago, "drives like Varzi."
