The more powerful 6C 1750 (1,752&nbsp;cc, 65 x 88&nbsp;mm) was introduced in 1929 in Rome. The car had a top speed of {{convertcvt|95|mi/h|km/h|abbrorder=onflip}}, a chassis designed to flex and undulate over uneven surfaces, as well as sensitive geared-up steering.<ref name=simeone>{{cite web|last1=Simeone|first1=Frederick|title=1929 Alfa Romeo 6C 1750 SS|url=http://www.simeonemuseum.org/the-collection/automobile-racing-club-of-america/1929-alfa-romeo-6c-1750-ss|publisher=Simeone Foundation Automotive Museum|access-date=10 March 2015}}</ref> It was produced in six series between 1929 and 1933. The base model had a single overhead cam. Super Sport and Gran Sport versions had a double overhead cam engine (DOHC). Again, a supercharger was available. Most of the cars were sold as rolling chassis and bodied by coachbuilders such as [[Zagato]], and [[Carrozzeria Touring|Touring Superleggera]]. Additionally there were 3 examples built with [[James Young (coachbuilder)|James Young]] bodywork, one of which is a part of the permanent collection at the [[Simeone Foundation Automotive Museum]] in Philadelphia, PA, USA, in original and unrestored condition.<ref name=simeone/>
