This was the year that Nuvolari achieved the 'Impossible Victory', which many regard as the greatest win in all of motor racing history: driving an outclassed Alfa Romeo P3 (3167 cc, supercharged, 265 hp) in the German Grand Prix at the Nürburgring, he beat all the dominant German cars—five Mercedes-Benz W25s (3990 cm³, 8C, supercharged, driven by Caracciola, Fagioli, Lang, von Brauchitsch, and Geyer), and four Auto Union Bs (4950 cc, 16C, supercharged, driven by Rosemeyer, Varzi, Stuck, and Pietsch). The crowd of 300,000 applauded Nuvolari, but the representatives of the Third Reich were enraged.
