On the eve of the international exhibition 2011 (IAA) in Frankfurt am Main, represented the new Audi A5 Audi DTM: after the V8 Quattro (1990-1992) and A4 (2004-2011), the brand with the four rings with a door in the most popular international tourist chose for the first time.
The new Audi A5 DTM, internal project name "R17" by Audi Sport is compatible with the new regulation technology, after entry into force of the season 2012. vehicle safety, reduced by up to 40% and a spectacular exterior design costs: the project has three main goals.
Room 2011 visitors can car 25 get an idea of the appearance of the New Testament Audi in Hall 13-September, 2011 take place. Audi A5 DTM is smaller and more robust than its predecessor, the success with the DTM, Audi has won four of the last seven titles. In the body, carbon, one new type of chassis with a hybrid design made is. The combination of a cage made of sheet steel monocoque carbon fibers and sets new safety standards for a race car. In addition, the chassis is one of more than 50 components that are all DTM vehicles.
"Because of these similarities, it was possible to achieve the cost up to 40% without the safety and attractiveness of the DTM cars", says the Director of Audi Motorsport Dr Wolfgang Ullrich, responsible for the development of the new DTM for Audi A5.

Audi A5 DTM is 5.01 M long, 1.95 m wide and 1.15 metres below. The wheelbase of the DTM cars are identical, 2,750 mm. Like its predecessor, the A5 DTM is powered by a V8 engine of with an output of 340 kW (460 HP). Box six speed, is now with pallets of change of the wheel of the pneumatic control system for a new development. The sequence of events is more accurate, that allow the conventional manual progress and change the performance of the aircraft, which has quadrupled to a maximum of 24 000 kilometers.
(Bosch MS 5.1) electronic engine control, operation without backups, and the main screen already, used in the Audi R8 LMS of the art are also state. Exclusive partner of Hankook Tire to larger and wider, tires with similar dimensions to the of the LMP2 sports car.
Insurance with a capacity of 120 litres fuel tank is embedded in the cell A5 Audi DTM carbon fiber. This would cover the actual distance between a DTM race without aerial refueling. Developed for quick charging of short.

The casing of the engine in the front and rear wheel are the same for all the DTM cars drive and engineers limit the suspension mounted on these components need to be shared. Steel as a material for the dimensions of the pipes can specify also Ay weapons. With the company Carrefour, create you the rules, the materials and the manufacturing process used. A piece of aluminum produced with a minimum weight limit. In addition, a provision of the regulations strictly define is you the hubs of the wheels and tyres for all participants.
Possibilities are limited in the field of aerodynamics. Air circulates in the body, as in the current A4 DTM and complex wing on the back and it is not allowed. This creates a strong similarity between the race and the standard of model cars. At the same time new vehicles that meet less sensitive physical contact DTM with other vehicles and to improve you with wider rear fenders.

"In the past, Audi very innovative, was especially in the area of aerodynamics in the DTM," says Dr. Martin mill Meier, Chief Engineer of the Audi Sport. "These areas were serious restrictions remain a subject good detailed solutions to crucial for the realization of the benefits of competition."
"R17" was published in May 2010 and a month later, decided that the A5 would serve as a basic model. A model wind tunnel testing was conducted from February 2011. The operation was a success, on 29 July 2011 Martin Tomczyk. Since then, the test A5 DTM Audi was constant. The assumption of A5 DTM is planned in March 2012, until then, Audi Sport in Ingolstadt and Neckarsulm to refine time on the detailed solutions engineers.
