| Competition history | |
The Alfa Romeo 6C name was used on road, race, and sports cars produced between 1927 and 1954 by Alfa Romeo; the "6C" name refers to six cylinders of the car's straight-six engine. Bodies for these cars were made by coachbuilders such as James Young, Zagato, Touring, Castagna, and Pininfarina. Starting from 1933 there was also a 6C version with a factory Alfa body, built in Portello. In the early 1920s Vittorio Jano got a task to create a lightweight, high performance vehicle to replace the Giuseppe Merosi designed RL and RM models. The car was introduced in April 1925 at the Salone dell’ Automobile di Milano as the 6C 1500. It was based on the P2 racing car, using single overhead cam 1,487 cc inline six-cylinder motor producing 44 horsepower, in the 1928 was presented the 1500 Sport which was the first Alfa Romeo road car with double overhead camshafts.
In the mid-1920s, Alfa's RL was considered too large and heavy, so a new development began. The 2-liter formula that had led to Alfa Romeo winning the Automobile World Championship in 1925, changed to 1.5 liter for the 1926 season. The 6C 1500 was introduced in 1925 at the Milan Motor Show, production started 1927, with the P2 Grand Prix car as starting point. Engine capacity was now 1487 cc, against the P2's 1987 cc, while supercharging was dropped. First versions were bodied by Young and Touring.
In 1928, a 6C Sport was released, with a dual overhead camshafts engine. Its sport version won many races, including the 1928 Mille Miglia. Total production was 3000 (200 with DOHC engine). Ten copies of a supercharged (compressore, compressor) Super Sport variant were also made.
