The Audi A5 DTM, was developed under the project ‘R17’ internally at Audi complies with the new technical that come into for the 2012 season. At the same the responsible parties also three premises: car safety, a reduction of up to 40 per cent and a spectacular

The final aspect is visible at glance. The Audi A5 DTM appears and squatter than its predecessor the A4 DTM which Audi won five of the eight DTM titles. A new and innovative in hybrid design hides the bodywork manufactured entirely carbon. With its front, and lateral crash elements the of carbonfiber monocoque and steel sets new standards with to safety for a racing touring

Furthermore, the chassis, which just 160 kilograms, is one of about 50 components shared by all DTM cars.

“Thanks to these standard it was possible to achieve the targeted reduction of up to 40 per cent while improving the safety and appeal of DTM says Head of Audi Dr. Wolfgang Ullrich under supervision the new Audi A5 DTM was developed.

The A5 DTM is meters long, 1.95 wide and only 1.15 high. The wheelbase of every DTM car is a 2.750 millimeters. Like its the A5 DTM is powered by a near 340 kW (460 hp) Sport V8 engine. A new development partner Hewland is the six-speed now activated pneumatically via shift mounted on the steering wheel.

compared to a classic manual the more precise gear procedure facilitates a significant in gearbox service life of up to kilometers.

The Bosch MS 5.1 engine which function without and the central display already in the Audi R8 LMS are also state-of-the-art. The tire partner Hankook larger and wider tires the of which resemble those on LMP2 sportscars. Integrated the Audi A5 DTM carbon fiber is a 120 liter safety fuel with which the current DTM distance can be completed making a for fuel – since refueling a DTM race is no longer permitted for reasons.

“In general new standards are set with the explains Stefan Aicher, of Vehicle Design at Audi “The monocoque weighs 126 kilograms, the roll-cage 32.5 At the same time the safety have increased dramatically. The is extremely stable when to not just frontal, longitudinal but also side impacts.

The sidewall must withstand a of 360 kN during the side impact this equates to around 36 By way of comparison, this value was 80 kN for the A4 which demonstrated its high standards in several spectacular

Only the engine subframe at the and gearbox at the rear restrict the freedom as far as the suspension geometry is The suspension pick-up points be mounted to these standard In addition, the material, steel, and dimensions are fixed and numerous defined by the regulations – the wheels for

Aerodynamic possibilities were restricted. Air flow through the as seen on the A4 DTM and complex additional at the rear are now prohibited.

Visual to the production line model is greater as a result and, at the time, the new DTM cars should less sensitively to contact and a better slipstream – also to the larger rear wing.

“Audi had very innovative in the past in the DTM and especially for the aerodynamics,” Dr. Martin Mühlmeier, Head of at Audi Sport. “Since areas were strongly it is now more about detail to acquire an advantage over the Audi was also always a in these areas over the I think that we’ve interesting and innovative details once again.”

Project began in May 2010, a month the green light was given to use the A5 as model. Tests in the model tunnel have been since February 2011. The was completed on 29 July 2011. the intensive test program at various European race and continued to the Deutscher Motor Bund (DMSB) homologation on March 1, 2012.

Since the most important technical on the new DTM cars were frozen for the of the season – including the still all aerodynamic configuration.

As usual, for this reason, all manufacturers kept their aero configuration as secret as to the last moment. “In the DTM this even more value is to every tiny detail ever before,” knows Dr. Ullrich. “And, it goes saying that we have over the last few month we wish to keep to ourselves for as as possible.”
