The 6C 1750 was a thrilling touring car available in single-cam Turismo and twin-cam Sport (later Gran Turismo) versions, known for its combination of lightness and high performance. Depending on the coachwork, it could reach speeds of over 120 km/h (75 mph).
Targeted at racing enthusiasts, there was also a limited edition Super Sport (‘SS’) model, which later became the Gran Sport. Produced from 1929, the SS came with or without a Roots-type supercharger, with a production split of 52/60 (blown/un-blown). Many had bodies by Carrozzeria Zagato, Carrozzeria Touring, and James Young for those imported into the UK.
The Alfa Romeo 6C 1750 SS was a highly popular and successful sports-racing car, with 26 of them competing in the 1929 Mille Miglia, where 25 finished, and six were among the top ten. Giuseppe Campari and Giulio Ramponi, driving a 6C 1750 SS, secured victory in the race for the second consecutive year.
This model also triumphed in high-profile events like the 24 Hours of Spa Francorchamps, Grand Prix of Ireland, and the 12 Hours of San Sebastian in 1929, as well as the 24 Hours of Spa Francorchamps and RAC Tourist Trophy in 1930. The 1750’s racing success, coupled with its mechanical durability, extended well beyond its production years, which ended in 1933.
