Like all racing cars in the DTM it is based on the C-Class W203 DTM and looked like the eponymous series cars. The prototype was constructed on a CFK - monocoque chassis with an integrated 15.4-imperial gallons fuel tank. Since refuelling at this time was still allowed in the race, a 26.4-imperial gallons tank was not built as from 2012. The C-Class W204 DTM is powered by a 4,000 cc (4.0 L; 244.1 cu in) Mercedes-Benznaturally-aspiratedV8 engine, power output approximately 476 hp (355 kW; 483 PS) and maximum torque approximately 490 N⋅m (361 lbf⋅ft). The rear-wheel drive C-Class DTM also has a sequential 6-speed sports transmission, a 3-plate carbon fiber clutch supplied by Sandtler (2007-2010), then ZF (2011) and an adjustable multi-disc limited-slip differential, check by mercedes diagnostic tool.
