Model change in the DTM: From 2012 on, Audi will bank on the A5 in the most popular international touring car racing series. The coupe, which is internally named “R17,” will replace the four-door A4 DTM with which Audi has won the prestigious DTM title four times since 2004.
The technically and visually upgraded A5 that is will be arriving at dealerships shortly provides the basis for the new DTM car. “In 2012 new Technical Regulations will come into effect in the DTM,” says Head of Audi Motorsport Dr. Wolfgang Ullrich. “We’ve got exactly the right model for that in the A5. We’re convinced that we’ll be able to continue Audi’s success story with it in the DTM.”
The new technical specifications have been worked out by the German Motorsport Association (DMSB) and the DTM umbrella organization ITR in close cooperation with the automobile manufacturers and are setting new standards particularly in terms of safety. “Our engineers have been involved in bringing up safety in the DTM, which had already been high before, to the highest possible level,” explains Dr. Ullrich. “At Le Mans this year we learned again that our concept of designing safety structures is a very good and appropriate one. This is exactly what we’ve been trying to feed into the DTM’s safety concept together with our colleagues from BMW and Mercedes-Benz. This new principle is an outstanding example of what is possible when employees of three premium manufacturers try to achieve a common aim: to get the best possible, lowest-cost and safest vehicle – and a fantastic car in general – off the ground.”
Underneath the carbon body is a new type of hybrid chassis construction. The combination of a carbon fiber monocoque and steel rollcage sets new standards in terms of safety for a touring car. The chassis is one of more than 50 components which are identical for all DTM vehicles, which all share a 108” wheelbase.
"Due to these shared components, it was possible to achieve the cost reduction target of up to 40 percent without compromising safety," explained Dr Wolfgang Ullrich of Audi Motorsport, who was in charge of the Audi A5 DTM development. Like its predecessor, the A5 DTM is powered by a 460hp V8 engine. The six-speed transmission, now pneumatically operated by paddle shifters on the steering wheel, is new. The shifting is more precise than conventional manual shifts and allow the unit to last four-times longer, up to 15000 miles.
ENGINE
The A5 DTM is 5.01 meters long, 1.95 meters wide, and 1.15 meters low, and is completely made in carbon fiber. It is powered by a V8 engine mated to six-speed transmission, now pneumatically operated using paddle shifters in the steering wheel. The shifting events are more precise compared with conventional manual gearshifts and allow the mileage of the unit to be quadrupled to up to 24,000 kilometers. The whole setup delivers a total of 460 HP. The race car has also received a safety fuel tank with a capacity of 120 liters integrated with the carbon fiber cell of the Audi A5 DTM that allows the current distance of a DTM race to be covered without a refueling stop.
