STM Mercedes-AMG C63 Saison 9

The DTM AMG-Mercedes C-Coupe was designed to meet the new and improved safety concept for 2012, which includes a state-of-the-art carbon fibre monocoque and a roll cage made of high strength steel. In order to improve driver protection in the event of an accident, all safety-related components such as the fire extinguishing system and fuel tank have been incorporated into the monocoque. Furthermore, each vehicle is equipped with six crash structures to give the driver additional protection to the front, rear and sides. These carbon fibre crash structures are designed to gradually absorb impact energy, so that the driver is not exposed to high deceleration forces.

The new safety concept was developed jointly by rights holder and promoter ITR e.V., the DMSB and the three manufacturers - Audi, BMW and Mercedes-Benz. In order to verify the performance of the DTM safety concept, the DMSB developed a test programme, which was carried out and analyzed by DEKRA, the independent testing organization. All tests were completed without any problems.

The new DTM AMG-Mercedes C-Coupe is based on the latest Mercedes-Benz C-Class Coupe, which celebrated its world premiere in autumn 2011.

The Mercedes-Benz C-Coupe DTM was built to supersede the Mercedes-Benz C-Class race car, a chassis was made directly connected to the carbon fibre monocoque is a roll cage of high-strength steel; CFRP crash elements on the side, front and rear.

At the beginning of the 2012 season, homologation rules for DTM cars were changed, an increase in minimum weight from 1,050 kg to 1,110 kg was mandated.
