Evolution of the "6C 1500", the Alfa Romeo 6C 1750 is a milestone, a genuine legend in the history of Alfa Romeo and of motorsports in general.
The range of the Alfa Romeo 6C 1750 at the end of the twenties featured four body types – the Sport, the Berlina, the Torpedo and the Spider – in addition to Super Sport. A spider and convertible known as Gran Sport and fitting a volumetric supercharger appeared in the 4th and 5th series.Milan-based coachbuilder Zagato made several sporty-looking spiders that would become famous for their achievements 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-6 with two overhead cams and lobe volumetric 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 just 840 kg, this 1750 GS clocked a top speed of 170 km/h.
Not by chance, the most famous 6C 1750 Gran Sport is one of Zagato's. Its fame still echoes today in glossy magazines and on the posters of historic race re-enactments. Its characteristic snout with three red-capped headlights caps is a firm favourite of all motorsports enthusiasts and not only Alfa Romeo fans.
