The Alfa Romeo 6C name was used on road, race and sports cars made between 1925–1954 by Alfa Romeo. 6C refers to to a straight 6 engine. Bodies to 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.
