The 1931 Grand Prix season was the first AIACR European Championship season. The championship was won by Ferdinando Minoia, driving for the Alfa Corse team. Minoia won the championship despite not winning a single race during the championship season.[1]
Similar to the modern FIA World Endurance Championship, all championship races were endurance events, each lasting ten hours, so most cars utilised more than one driver.[2][3][4]
