The 1930 and 1933 races were cancelled due to economic reasons related to the Great Depression. In 1931, the event began to use only the 14.2-mile (22.8 km) "Nordschleife" (North Loop), and this would continue onwards throughout the century. Caracciola would win the 1931 and 1932 events in a Mercedes and an Alfa Romeo respectively. Starting in 1934, there were often several races each year with the so-called "Silver Arrows" "Grand Prix" cars in Germany, e.g. the "Eifelrennen", the AVUS race and several hillclimbs. Yet it was only the Grand Prix at the Nürburgring that was the national "Grande Epreuve", which counted toward the European Championship from 1935 to 1939. The 1935 event was considered to be one of the greatest motorsports victories of all time. Italian legend Tazio Nuvolari, driving a hopelessly outdated and underpowered Alfa Romeo against state-of-the-art Mercedes and Auto Unions drove a very hard race in appalling conditions. After a dreadful start, he was able to pass a number of cars, particularly while some of the German cars pitted. But after a botched pit stop that cost him six minutes, he drove on the limit, made up that time and was second by the start of the last lap; 35 seconds behind leader Manfred von Brauchitsch in a Mercedes. Von Brauchitsch had ruined his tyres by pushing very hard in the dreadful conditions and Nuvolari was able to catch the German and take victory in front of the stunned German High Command and 350,000 spectators. The small 42-year-old Italian ended up finishing in front of eight running Silver Arrows. Second placed Hans Stuck was two minutes behind Nuvolari.
