Airfield Diepholz Racetrack

History and photos by Dieter C. Serowy

The Airfield Diepholz is located in Lower Saxony, a northern part of Germany. It was built in the 1930s and used as a german airbase in the Second World War. The airfield was destroyed in the war and got rebuild as a military airbase in the 1950s. The German Airforce still uses the airfield.

The german motorsport in the 1960s suffered very much from a lack of circuits. The old N¸rburgring and the 1966 opened new Hockenheim-Motodrom were the only two permanent race tracks at that time. Looking for alternatives, races on military airfields became quite popular. Untill the 1990s, tracks like Wunstorf, Mainz-Finthen, Kassel-Calden, Fassberg or Siegerland were used for german championship races. But the most popular airfield-race in Germany used to be at Diepholz.

In 1968, the local motorsport-club AMC Diepholz organized the first "ADAC-Flugplatzrennen Diepholz". The anual event soon became quite popular, due to the fact that race-director Peter Rumpfkeil and his team not only proved to be able to well-organize the races but also to bring the stars of international motorsport to Diepholz.

From the start of the championship in 1972, the Diepholz-Race was included in the "Deutsche Rennsport-Meisterschaft" (DRM), the most famous touring-car-championship of the 1970s. The best touring-car-pilots of that time - like Dieter Glemser, Frank Gardner, Hans Heyer, Toine Hezemans, Helmut Kelleners, Karl-Heinz Becker, Bob Wollek or Albrecht Krebs - raced at Diepholz. 1977 saw one of the most spectaculous races in the history of Diepholz: In that season, BMW and Ford battled in the DRM. The Bavarians ran three works-cars with the youngsters Eddie Cheever, Marc Surer and Manfred Winkelhock - the so-called "BMW-Junior-Team". Their appearences were sucessful but the youngsters got a bit wild on the track. At the Norisring-race, Surer attacked Ford-driver Hans Heyer in such a brutal way that both cars were totally smashed. BMW Motorsport-Director Neerpasch wanted to cool things down and for the Diepholz-race the "Junior-Team" was replaced by the "Gentleman-Team"- Hans-Joachim Stuck, Ronnie Peterson and David Hobbs. Bad luck for Neerpasch, Stuck and Peterson didn't act like elder statesmen of motorsport. In the pouring rain they had their private battle which ended almost dramaticly: Peterson missed his breaking point at the end of the s/f-straight, hitting some water-tons, smashing his BMW 320 and stopping just some centimetres away from the spectators. Many other drivers spun on the slippery track and it was Hans-Joachim Stuck who won after an error-free race.

After this race - and the Peterson-incident - there was a lot of criticism in the press about safety at Diepholz. And the teams complained about the damaged cars. At that time, the chicanes in Diepholz were marked by old watertons and old tyres - hitting either of them meant a lot of work for the mechanics. So the DRM decided not to return to Diepholz in 1978. Peter Rumpfkeil had to come up with a new idea - and he did: He brought 20 Chevrolet Camaro from Sweden to Diepholz for the "Camaro-Supercup 1978". And of course he managed to have drivers like Stuck, Mass and Stommelen in those cars. The fans were enthusiastic and the show was perfect. And in 1979 the DRM returned to Diepholz....

At the end of 1980 the DRM seemed to face a crisis for 1981. And so Rumpfkeil cancelled the DRM-races in favour of having an outstanding one-off event: The "German Race of Champions". The entry-list of that race in 1981 is a who-is-who of motorsport at that time: F1-Champion Alan Jones, John Watson, Hans-Joachim Stuck, Hans Heyer, Rally-Champion Walter Röhrl, Björn Waldegaard, Michele Mouton and many more. On identical cars - Ford Escort XR3 - they offered brillant entertainment for the fans at Diepholz and on TV. And it was Hans-Joachim Stuck who proved to be the Champion of the Champions, winning the race.

In 1983 the Group-C-Sportscars made their first appearence on the airfield. The Porsche 956 and 962 Turbo, the most impressive Sauber-Mercedes C9 Turbo and Nissan Turbos remain as the fastest cars ever to race on this track - cars with up to 900 hp. But a new german touring-car-championship called "Deutsche Tourenwagen-Meisterschaft" (DTM) soon proved to be more popular than the powerful sportscars. The DTM raced at Diepholz in 1984 and 1985, but it all ended up in a scandal. The touring cars had to have noise-reduction but Rumpfkeil wanted to have racing-sounds on the airfield. So he encouraged the teams to run the cars without noise-reduction-exhausts. Some teams did, others did not. There were protests, Rumpfkeil got in trouble with the national motorsport association and Diepholz lost the DTM-races until 1989.

When the DTM returned in 1989, the circuit had changed: The old watertons and tyres had gone. They had been replaced by plastic-kerbs, which were installed especially for the race-weekend and which were removed afterwards. The track-layout had also changed. Up to 1996 - the last year of the DTM - Diepholz was part of the championship. Still it was a non-permanent race-track and it was a huge amount of work necessary to keep the DTM-race: e.g. installing stands for the spectators, the kerbs, barriers, the paddock. In 1996 Rumpfkeil and his team even had to add a gravel-trap at the end of the s/f-straight. Still the teams had to improvise as there were no pit-buildings. And the drivers had mixed emotions about the track itself with the superfast chicanes on the s/f-straight.

About 60 000 spectators watched the races in 1996 - the biggest crowd ever. And it was the last highlight in the history of the Diepholz-races. The DTM/ITC collapsed at the end of the season. Meanwhile, Peter Rumpfkeil was the driving force behind the new permanent circuit at Oschersleben and so the days of the races at Diepholz were counted.

1997 saw the anual event take place with some minor races. The final curtain fell in 1998 - exactly thirty years after the first race at the airfield.
