Like all of the 6C series, the 1930 6C-1750 Gran Sport (GS) benefited from Vittorio Jano’s excellent engineering and design principles. It was an updated version of the 6C-1750 Super Sport from 1929 which had similar specification. Engine now developed 102 hp. New to the Gran Sport was shorter wheelbase that was reduced 50 mm with shorter rear leaf springs. The slightly smaller fuel tank was repositioned behind the rear wheels and the battery box was moved from the fender to inside the cockpit. The first big win of the GS was at the 1930 Mille Miglia, where Tazio Nuvolari won in an epic duel with Achille Varzi.
For the 1931 Targa Florio Alfa Romeo entered two new 2300, 8-cylinder racecars for Tazio Nuvolari and Luigi Arcangeli. Giuseppe Campari, Baconin Borzacchini, and Guido D’Ippolito were to race with the well-tried 6-cylinder 1750 cars. Tazio Nuvolari dominated the race, and Borzacchini finished second. Campari was fourth behind Achille Varzi in Bugatti, and d’Ippolito finished fifth.
