The Audi A4 DTM is a 4-door touring car (DTM) constructed by the German car manufacturer Audi. It was first developed for use in the 2004 DTM season, replacing the Audi TT DTM at the end of 2003 DTM season. Based on the Audi A4, it was continually improved over the course of six face-lifts between 2004 and 2011. The Audi A4 DTM was succeeded by the Audi A5 DTM in 2012.
Comeback as a factory team
After the private Team Abt Audi TT-R was raced from 2000 to 2003 with Laurent Aiello, Audi reentered the DTM series with a factory team. Audi's comeback resulted in a successful start and finish with titles for the driver, team, and manufacturer rating of the championship race.[1]
Technical details
Like all DTM racing cars, the A4 DTM resembles its A4 production equivalent only in cosmetic appearance.[2] The A4 DTM is constructed with a carbon fiber reinforced plastic monocoque chassis and an integrated 15.4 imp gal (70 L; 18 US gal) fuel tank.[2] Powered by a 4,000 cc (4.0 L; 244.1 cu in) Audi naturally-aspirated V8 engine, it has a power output of approximately 460 hp (343 kW; 466 PS) and a maximum torque of more than 500 N·m (370 ft·lbf). The rear-wheel drive A4 DTM also has a sequential 6-speed transmission, a 3-plate carbon fiber clutch supplied by Sandtler (2004-2010) and ZF (2011), and an adjustable multi-disc limited-slip differential.
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.[3] 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.[3]
