A Ferrari Monza is one of a series of cars built by Ferrari. In the early 1950s, Ferrari shifted from using the compact Gioacchino Colombo-designed V12 engine in its smallest class of sports racers to a line of four cylinder engines designed by Aurelio Lampredi. Inspired by the success of the light and reliable 2.5 L 553 F1 car, the four cylinder sports racers competed successfully through the late 1950s, culminating with the famed 500 Mondial and 750 Monza.
One important stylistic difference between most four-cylinder Ferraris is that they lacked the hood scoops common on V12 models. The V12 cars used downdraft carburettors located centrally in the "valley" of the engine, while the inline-engined fours used side-draft units and thus did not need the hood scoops.
