Audi will tackle the 2013 season with an optimised organisational structure, having appointed former F1 engineer Dieter Gass as its new 'head of DTM'.

Gass, who worked with Toyota and the Lotus/Caterham squads during his time in the top flight, will be responsible for the eight Audi RS5s racing this season, while Christopher Reinke assumes the corresponding role for the marque's Le Mans Prototypes. Both men will report directly to head of Audi Motorsport Dr. Wolfgang Ullrich.

"With the new structure at Audi Sport, we react to the growing demands and the increasingly tough competition in the DTM and in the FIA World Endurance Championship," technical development board member Wolfgang D?rheimer commented, "Both programmes are of great importance for our company and this forward-looking arrangement will be the base for future motorsport projects."

The appointment marks a return to Audi for 50-year old Gass, who was a technician at Audi Sport between November 1994 and March 2001. He then worked in F1 for ten years before rejoining Audi Sport as 'head of racing commitments' in January 2012.

"Dieter Gass was a logical choice for the new position owing to the extent of his experience," Ullrich concluded.
