At the official DTM test at Mugello (Italy) between 8 and 11 March, defending champion Audi presents three new partners for the 2005 DTM season: SONAX, the Audi Bank and Audi Gebrauchtwagen:plus use the successful AUDI AG involvement in Europe's most popular touring car series to present its products and services to an audience of millions. SONAX is one of the world's leading manufacturers of car care products and market leader in Germany and was an Audi partner in the DTM during the years 1990 and 1991.

- SONAX and Audi Bank advertise on the Audi A4 DTM
- Audi Gebrauchtwagen:plus goes to the grid
- quattro GmbH again partner in the DTM

During the 2005 season the six-time Le Mans winner Tom Kristensen and DTM newcomer Frank Stippler compete with two Audi A4 DTM cars in the SONAX design and that of S line, the sport and tuning kits from quattro GmbH.

Also for the Audi Bank, one of Europe's leading automotive financial service providers, the DTM is no unknown territory: In 2003 the Audi Bank supported the juniors Peter Terting and Martin Tomczyk. The two Audi A4 DTM cars of Christian Abt and Pierre Kaffer carry the Audi Bank name in the 2005 DTM.

On both the silver and grey painted year-old cars, AUDI AG also presents its new programme Audi Gebrauchtwagen:plus, which is launched at the Audi partners parallel to the start of the DTM season in April 2005.

The new colours can be seen on the Audi A4 DTM cars for the first time at the DTM test at Mugello, which will be run by Audi Sport Team Joest. After a test scheduled for the end of February at Hockenheim fell victim to adverse weather conditions, Christian Abt, Rinaldo Capello, Pierre Kaffer and Frank Stippler now have the opportunity to test their race cars for the 2005 season for four days.

At the next official DTM test between 29 March and 1 April at Spa-Francorchamps (Belgium) all eight Audi DTM drivers should be in action.
