After the private Team Abt Audi TT-R was raced from 2000 to 2003, Audi re-entered the DTM series with a factory team since 1992. Audi's comeback resulted in a successful start and finish with titles for the driver, team, and manufacturer rating of the championship race.[1]
Production A4 DTM Edition
To celebrate its first DTM championship title win in 2004, Audi released a production variant of the A4 called the DTM from 2005 to 2007.[2] It featured an additional 20-horsepower over the standard model, sports-styled exterior features, and a new version of the quattro all-wheel-drive system.[2]
