The Audi V8 quattro DTM (internal R6) is a touring car from Audi and was used in the German Touring Car Championship from 1990 to 1992 . The Audi V8 D11 served as the basis . This makes it the third racing car based on the C3 platform, alongside the Audi 200 quattro Rallye and the Audi 200 quattro Trans-Am . After successes in the World Rally Championship and in the USA in the Trans-Am series and the IMSA-GTO , Audi wanted to demonstrate the advantages of the quattro permanent all-wheel drive on home soil from 1990 onwards . The Audi drove in competition with the other two German premium manufacturers BMW and Mercedes-Benz .

drive

The engine of the V8 quattro DTM is based on the 8-cylinder V-engine with a displacement of 3.6 liters from the series. At the beginning of the 1990 season, it had an output of around 309 kW (420 hp) and has been continuously developed over the years. Audi was able to improve the engine's response behavior and increase torque and power, among other things with an oil slicer for the wet sump , which prevents the crankshaft from dipping into the oil during high lateral acceleration and making it frothy. In the last race in 1992, 340 kW (462 hp) were available. Power is transmitted via a 6-speed manual transmission and, just like in series production, via the quattro permanent all-wheel drive.

body

In 1990, in its first year of involvement in the DTM, Audi used the series body of the V8 quattro. The vehicle was homologated according to the Group A regulations , which means that the external appearance of the vehicle remained almost unchanged. On high-speed courses such as the AVUS or at the Wunstorf Air Base, however, the V8 quattro generated lift, which caused the top speed to suffer. That is why Audi brought an evolution model with sliding spoilers for homologation in 1991. These spoilers created significantly more downforce. In the interior, the dashboard and door panels from the series had to be retained. The minimum weight varied over the years between 1220 and 1300 kg. Most recently, the V8 quattro weighed 320 kg more than the competition in the form of the Mercedes 190E 2.5-16 Evo 2 and BMW M3 Sport Evolution .

1990 season

When Audi announced that it would be competing in the DTM in 1990, it was the choice of the vehicle that caused a sensation. Hardly anyone expected a full-size sedan in the DTM. Since turbo engines have been banned in the DTM since 1990, the in-line five-cylinder turbo engine, which has proven itself in motorsport, could not be used. Audi was therefore unable to start with the Audi 90 quattro , which had already been successfully used in racing as the 90 quattro IMSA GTO .

The vehicles for the 1990 season were prepared by Konrad Schmidt Motorsport GmbH , SMS for short. At the beginning of the season, only one vehicle was used, which was driven by Hans-Joachim Stuck . Stuck was already on the podium in the second race in Zolder on the first race weekend . At the AVUS he was able to win both races and thus achieve the first victories for Audi. From the eighth race weekend at the Norisring , he received support from two-time rally world champion Walter Röhrl , who drove the second V8 quattro DTM for the rest of the season. In his first race, Röhrl led to the last lap and then let Stuck pass in favor of the championship. On the last race weekend at the Hockenheimring , four other drivers besides Stuck had a chance for the title. Each manufacturer signed guest starters for the last two races. Frank Jelinski drove for Audi , who played an important role in the fight for the title with his two second places. With triple victories in both races, Audi and Hans-Joachim Stuck secured the championship. The Audi V8 quattro DTM won the title in its first year of racing.

1991 season

For the 1991 season, Audi competed with four V8 quattro DTMs right from the start. Hans-Joachim Stuck and the young driver Hubert Haupt drove for the SMS team, Frank Biela and Frank Jelinski started the season with the new team from the Audi Zentrum Reutlingen (AZR). The new V8 quattro were evolutionary models with spoilers at the front and rear. A duel for the title between Stuck and Biela emerged relatively quickly. Both were able to win a run at AVUS each. At the last race weekend at Hockenheim, the two were separated by only a few points. Walter Röhrl was once again committed to replace Hubert Haupt for this race weekend. Stuck had a defect in the speed sensor in the first run, which threw him far back and cost the title chances. Frank Biela won both runs and won the championship. It was the first title defense in the history of the DTM.

1992 season

The regulations were adjusted for the 1992 season and the V8 quattro DTM became even heavier. In order to keep up with the competition, Audi developed a new crankshaft with a journal offset of 180 ° instead of the 90 ° in the series V8. Since a different crankshaft was not permitted according to the Group A regulations, Audi resorted to a trick. The original crankshaft with a 90 ° pin offset was twisted in its raw state, so the series part was retained. BMW lodged a protest with the ONS , which declared the part legal. Mercedes also protested against the loophole in the regulations later. In the second instance, too, the part was not declared illegal. Audi drove with this crankshaft on the first six race weekends and even clinched a triple victory at the Nürburgring. Due to the heavy weight, however, there were more punctures. Furthermore, the third generation V8 quattro DTM suffered from reliability problems. After the race weekend on the Nordschleife, the ONS appeals court ruled that the crankshaft of the Audi V8 quattro DTM is not permitted. Because of this decision, Audi withdrew from the DTM with immediate effect. The V8 quattro DTM was then no longer used. Just a few weeks later, Audi began developing a super touring car based on the Audi 80 B4 .
