The first national Grand Prix event in German motor racing history was held at the AVUS circuit in southwestern Berlin in 1926. AVUS stood for Automobil Verkehrs und Übungs-Straße (Automobile Traffic and Practice Road), a circuit made up of two parallel six-mile straights connected at each end by hairpins. The 1926 race, run in heavy rain, was won by Germany's Rudolf Caracciola in a Mercedes-Benz, though the event was marred by a crash involving Adolf Rosenberger that killed three people. Because AVUS was considered excessively dangerous even by the standards of the time, the German Grand Prix was moved away from the Berlin circuit.
The German Grand Prix became an official championship event in 1929, by which time it had found a permanent home at the Nürburgring, a vast 28.3-kilometre circuit inaugurated in June 1927 in the Eifel Mountains about 70 miles from Cologne. Designed by architect Gustav Eichler's practice and constructed through the Eifel highlands, the Nürburgring was intended as a showcase for German automotive engineering. With over 300 metres of elevation change, more than 170 corners, and multiple sections where cars became airborne — including Flugplatz, Brunnchen and Pflanzgarten — it was unlike any other circuit in the world.
The 1930 and 1933 races were cancelled due to the economic difficulties of the Great Depression. From 1931 the race used only the Nordschleife, or North Loop, a 22.8-kilometre layout that remained the mainstay of the German Grand Prix for decades. Rudolf Caracciola won consecutive editions in 1931 and 1932 in a Mercedes and an Alfa Romeo respectively.
From 1934, the German Grand Prix became a showcase for state-sponsored German motorsport supremacy. Mercedes-Benz and Auto Union, their budgets underwritten by the Nazi government, brought technically advanced supercharged cars that dominated the European championship from 1934 to 1939. The German Grand Prix counted toward the European Championship throughout this period, and the annual confrontation at the Nürburgring attracted enormous crowds — an average of 375,000 spectators per year.
Caracciola won again in 1934 and 1937, accumulating six German Grand Prix victories in total over his career. Bernd Rosemeyer won for Auto Union in 1936, having earned the nickname "Fog Master" for his spectacular performances in treacherous conditions. Richard Seaman, a British driver in the Mercedes factory team, won in 1938 — his only championship Grand Prix victory, achieved on what was effectively hostile territory as a non-German winner in a German car during the Nazi era.
The 1937 race saw Ernst von Delius die of injuries sustained when his Auto Union struck the back of Seaman's Mercedes at high speed near the Antonius Bridge on the main straight. The dangers of the Nürburgring were constant and sometimes lethal; the track's enormous length and inaccessibility meant that accident response times were far longer than at any other circuit.
The greatest single moment of the prewar German Grand Prix came in 1935. Italian Tazio Nuvolari, driving an ageing and underpowered Alfa Romeo, faced the full might of the German Silver Arrows in front of 350,000 spectators and the Nazi High Command. After a poor start and a pit stop that cost him six minutes, Nuvolari launched a relentless charge. On the final lap he caught and passed the seemingly certain winner Manfred von Brauchitsch, whose Mercedes had worn its tyres to destruction while leading. Nuvolari won by a substantial margin over the remaining Silver Arrows. The sight of a 42-year-old Italian humiliating the entire German establishment on home soil in front of the country's political leadership became one of the defining legends of Grand Prix racing.
Caracciola took his sixth German Grand Prix victory in 1939, the last prewar edition. Plans for a 1940 German Grand Prix at a new Deutschlandring circuit near Dresden were made but never materialised due to the outbreak of the Second World War. The Nürburgring stood idle as a racing venue during the war years, returning to international competition only in 1951 when West Germany was readmitted to international sporting events.
The prewar German Grand Prix established the Nürburgring's reputation as the most challenging and demanding circuit in the world, a status it would maintain for decades. It also demonstrated, through Nuvolari's 1935 triumph, that sheer driving artistry could occasionally overcome technological superiority — a lesson that resonated far beyond the confines of motor sport.
