Alfa Romeo’s long-lived 6C model made its debut in 1925. It was designed by the brilliant engineer Vittorio Jano and first appeared with 1,487 cubic centimetres of displacement and a single overhead camshaft. Twin cams were introduced in 1928, and they were joined by a 1,750-cubic centimetre sibling a year later. That year, the 6C 1750 won every racing event it entered. A 1,900-cubic centimetre version came in 1933, followed by the 6C 2300 the next year. The final variant, the 2500, of which this car is an excellent example, was introduced in 1938, and it remained in production until 1952.
