Q:
A: I think you may have mixed up a word or two in your question as it doesn't make any sense. But you'll likely find your answer in this info: The first cars run in Grand Prix Racing (before F1) by Ferrari were Alfa Romeos. The engines in these cars were made by Alfa, though the engines and cars were prepped and modified by Ferrari. In the late 1930s, Ferrari began manufacturing their own cars (including the engine). And by the time that the Formula 1 Championship came to be, the cars and the engines for the Ferrari team, were made by Ferrari.
