Audi has presented its new A5 DTM car at the International Motor Show in Frankfurt. The car, internally codenamed the R17, has been built to the new technical regulations that come into force for the 2012 DTM season.

The body sits upon a spec chassis, one of more than 50 components that will be identical for all DTM cars. A combination of a carbonfibre monocoque and steel cage creates an improved safety standard.

“Due to these shared components it was possible to achieve the cost reduction target of up to 40 percent without compromising on the safety and attractiveness of the DTM vehicles,” said Head of Audi Motorsport Dr. Wolfgang Ullrich.

The car also includes a larger fuel tank with a capacity of 120 litres which will allow current DTM races to be covered without a refuelling stop, while a quick refuelling system is in development for longer races.

The regulations allow for less additional aerodynamic parts at the rear of the car, like on the current A4 DTM. This not only creates a stronger resemblance between the race car and its production model, but also make the cars less sensitive to contact.

“In the past, Audi has had very innovative solutions particularly in the area of aerodynamics in the DTM,” said Dr. Martin Muhlmeier, Head of Engineering at Audi Sport. “Since these areas have been subjected to severe restrictions good detailed solutions will now be crucial to achieving advantages over the competition.”

Testing of the car has already begun, while engineers have until the scheduled homologation date of 1 March 2012 to make adjustments.
