European Grand Prix
The European Grand Prix was created as an honorific title by the AIACR, the FIA's predecessor in the organisation of motor racing events. The first race to receive the title was the Italian Grand Prix, in 1923; the French Grand Prix followed in 1924 and the Belgian Grand Prix in 1925. After a hiatus in 1929, the Belgian race received the title in 1930, becoming the last race to do so before World War II.
German Grand Prix
The "Grand Prix" moved to the new, 28.3 km (17.6 mi) Nürburgring, located in the Eifel Mountain region in western Germany about 70 miles (112 km) from Frankfurt and Cologne. It was inaugurated on 18 June 1927 with the annual race, the ADAC "Eifelrennen". This was a huge, incredibly challenging racing circuit that sped and twisted through forests of the Eifel Mountains, and had over 1000 feet (300 m) of elevation change and many spots where the cars visibly left the ground, such as the Flugplatz, Brunnchen and Pflanzgarten sections. There were two more races on the "Gesamtstrecke" (Combined circuit) combined course, which were both sportscar races, where German pre-war great Rudolf Caracciola would win his second of six German Grands Prix.
