a coffin?" Nuvolari and co-driver Battista Guidotti won the Mille Miglia in a Zagato-bodied Alfa Romeo 6C 1750 GS, becoming the first to complete the race at an average of over . At night, leading on elapsed time but still lying behind his teammate Achille Varzi on the road because he had started after him, he tailed Varzi at speeds of up to with his headlights switched off, so that he could not be seen in the other car's rear-view mirrors. He eventually switched them on to overtake "the shocked" Varzi near the finish at Brescia. 1931 Towards the end of 1930, Nuvolari decided to stop racing motorcycles and concentrate fully on cars for 1931. Regulations for the season required Grand Prix races to be at least 10 hours long. For the Italian Grand Prix, Nuvolari was to share an Alfa Romeo with Baconin Borzacchini.

The pair took the race win, although Nuvolari could not receive the championship points. Apart from the Belgian Grand Prix, where he came second, the only other European Championship race was the French Grand Prix, where he finished 11th.

It was the only season in which Nuvolari regularly drove one of the fastest cars, the Alfa Romeo P3, and he took two wins and a second place from the three European Championship Grands Prix, plus victory in the championship by four points from Borzacchini. He achieved four other race wins that year, including the prestigious Monaco Grand Prix and a second Targa Florio. Of the latter, his mechanic Mabelli said: "Before the start, Nuvolari told me to go down on the floor of the car every time he shouts, which was a signal that he went to a curve too fast and that we need to lower the car's center of mass. I spent the whole race on the floor. Nuvolari started to shout in the first curve and wouldn't stop until the last one." On 28 April the writer Gabriele d'Annunzio gave him
