The debut of the supercharged sport version of the 6C 1750 Gran Sport came in the third Mille Miglia in 1929. It dominated sports car racing for 1929 and 1930 and repeated its Mille Miglia victory in 1930.
The car is powered by a water-cooled, double-overhead-cam, 1752cc, 6-cylinder engine coupled to a four-speed manual transmission. The competition version developed as much as 102 horsepower at 5000 RPM. This car was so outstandingly successful not because of outright speed - its absolute maximum was 105 mph - but because it was reliable and exhibited superb road handling.
A total of 369 Super Sport and Grand Sport 6C 1750s were built. This Zagato-bodied two-seat spider is typical of the 6C 1750 Grand Sport.
