Ingolstadt, 9 April, 2003

Five victories, six pole positions, six fastest race laps and, as jewel in the crown, the DTM title – the Abt-Audi TT-R was the most successful car during the 2002 season. Nevertheless, the Audi TT race version with approximately 455 hp was completely reworked for the 2003 DTM. “The basis remained unchanged, but all other details went under the microscope,” explained Albert Deuring, Technical Director at Team Abt Sportsline in Kempten.

The DTM regulations leave the engineers with little room to maneuver. The wheelbase and overhang dimensions are specified as well as the weight and material of many components.

A four-litre V8 power unit with a standard air intake restrictor is compulsory for all competitors. Other components such as the six-speed sequential gearbox, carbon fibre brakes, the tyres and engine electronics are the standard components of exclusive suppliers. This should prevent an expensive development escalation and simultaneously guarantee the best possible chance of equipment parity. Attention to detail counts in the DTM.

However, the modifications made to the Abt-Audi TT-R, now in its fourth generation, are visible at a glance when compared to last year’s model. Newly designed inner wheel arches guaranteed a lower drag coefficient and improved airflow over the biplane rear wing. The exhaust position is a novelty for a DTM car: The tailpipes now exit from the carbon fibre bodywork above the inner rear wheel arches instead of from the side.

Distinct changes were also made under the synthetic skin of the TT-R. The V8 engine, used for the first time last year, was reworked exactly as the oil cooling system and brakes were, as they will be subjected to even more stress than ever before because of the longer race distances (up to 170 kilometres) specified this year. Due to the longer race distance, the race will be more demanding for the drivers. In the TT-R cockpit, in which the driver sits embedded in a carbon fibre monocoque, provision was therefore made for an even better fresh air supply.

Regulation changes dictated several changes made to the TTR. With the introduction of fuel stops, the fuel system also had to be repackaged; the tank inlets are located in the right rear side screen.
