In the history of motorsports, the German Touring Car Championship, DTM was an absolute spectacle back in late 80’s. Those were the times when the championship was at its peak of being its most sideways, door-banging, thrilling self. It was a series drenched in the legacy of icons like the Mercedes 190 E 2.3 Cosworth. And then there was the BMW E30 M3 that had the sole purpose of beating the three pointed star in its own game. However, there was another legend that the world forgets to talk about among these amazing race cars. It was the Audi V8 Quattro DTM race car, a car that shook the championship completely. While its rivals were light and oversteer-ing wonders, the Audi was heavier and far more composed. Probably it was that lack of drama and theatrics which is why world forgets about the Audi V8 Quattro DTM race car.
But no one can deny that the acclaimed all-wheel drive Audi V8 Quattro DTM gripped and won at will. The 3.6-liter naturally aspirated Audi V8 Quattro DTM produced a staggering 414bhp@8200rpm and had a mammoth torque rating of 380Nm@6000rpm. Weighing around 1250kg, it wasn’t a light car as compared to its rivals. In fact, the Audi V8 Quattro DTM was almost 300kg heavier than the Mercedes and the BMW’s. However, its brilliant all-wheel drive system meant it never wasted any of its power in slides. All this power was transmitted by a 6-Speed manual gearbox, Wow! The car also had an option to chose from two types of centre differentials. The choices being a Torsen with a viscous coupling, or a planetary gear set with a viscous coupling. While the front had a viscous limited slip-diff, the rear had a clutch pack limited slip-diff.
The car was a true engineering masterpiece, and the Quattro system played a major role in that. The system kept the car from over-steering all over the place, and even if the car ever slid, it was much easier to control than its rivals. This can be attributed to Audi V8 Quattro DTM having 22 degrees of steering lock to BMW’s just 13. All this brilliant engineering meant that the Audi V8 Quattro DTM became the only DTM car to win back-to-back championships. The Audi V8 Quattro DTM won in 1990 and 1991 before the regulations changed in 1993. In 1990 Hans Stuck and Frank Biela in 1991 took the Audi V8 Quattro DTM to victory. In the video below Hans-Joachim Stuck talks about what made the Audi V8 Quattro DTM such a standout.
In 1992, Audi came with a new engine design that was a 180° flat-plane crankshaft. As per Audi, this new crankshaft was re-forged and bent from the production models 90° crossplane unit. However this new design was met with a dispute regarding its legality. This led to company withdrawing its team mid-season.
