1930 | Alfa Romeo 6C 1750 Gran Sport

Transmission: 4 gears, Manual gearbox

Evolution of the “6C 1500”, the Alfa Romeo 6C 1750 is a milestone, a true legend in the history of Alfa Romeo and motorsport in general.

In the late 1920s, the Alfa Romeo 6C 1750 range included four body types – the Sport, the Berlina, the Torpedo and the Spider – in addition to Super Sport. In the 4th and 5th series appeared a spider and convertible, known as Gran Sport and equipped with a volumetric supercharger. Milan-based coachbuilder Zagato made several sporty-looking Spiders that would become famous for their performance on the chassis of the most powerful 6C 1750 Gran Sport.

The engine, designed by Vittorio Jano and derived from the earlier “6C 1500”, is a 1752 cc straight-six engine with two overhead camshafts and a volumetric lobe supercharger. The original 85 hp of the straight-6 was increased to 102 hp in the so-called Testa Fissa (fixed head) versions. With a weight of only 840 kg, this 1750 GS reached a top speed of 170 km/h.produce
