At the Coppa Acerbo, Alfa Romeo's new 12C-37 car proved to be slow and unreliable. Frustrated, Nuvolari handed his car over to Giuseppe Farina mid-race. Not wanting to leave Alfa Romeo, he drove an Auto Union in the Swiss Grand Prix as a one-off. After the Italian Grand Prix, Alfa Romeo withdrew from racing for the remainder of the season and dismissed Vittorio Jano, its chief designer.
