After Alfa Romeo officially withdrew from Grand Prix racing Nuvolari drove for Enzo Ferrari's team, Scuderia Ferrari, who ran the Alfa Romeo cars semi-officially. In 1933 he won Le Mans in an Alfa Romeo as a member of Ferrari's team, and a month later won the Belgian Grand Prix in a works Maserati, having switched teams a week before the race. Mussolini helped persuade Ferrari to take Nuvolari back for 1935, and in that year he won the German Grand Prix in Ferrari's outdated Alfa Romeo, defeating more powerful rivals from Mercedes-Benz and Auto Union. It was the only time a non-German car won a European Championship race from 1935 to 1939.
