During the 1960s, although the company had no official presence in the top tier of motorsport a number of Formula One teams used independently developed Alfa Romeo engines to power their cars. In the early 1970s, Alfa provided Formula One support for their works driver Andrea de Adamich, supplying adapted versions of their 3-litre V8 engine from the Alfa Romeo Tipo 33/3 sports car to power Adamich's McLaren (1970) and March (1971) entries. None of these engine combinations scored championship points.
