The 275 F1 made its debut at the 1950 Belgian Grand Prix and belongs to the 375 F1 model range. It used the 3.3-liter version of Lampredi's new engine with three Weber carburetors, a single overhead camshaft per cylinder bank, and two valves per cylinder. Alberto Ascari drove it to fifth place. With that, the era of the 3.3-liter engine came to an end.
