Alfa Romeo 6C 1500
|Engine||1.5 L 1487 cc I6|
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 World Championship in 1925, changed to 1.5 liter for the 1926 season. The 6C1500 was introduced in 1925 at Milan, 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.
