2012 DTM Mercedes AMG C-Coupe

DTM AMG Mercedes C-Coupé_01The DTM Mercedes AMG C-Coupe is based on the latest Mercedes-Benz C-Class Coupe, which received its world premiere in summer 2011. HWA AG began development, design and construction of the DTM Mercedes AMG C-Coupé in June 2010. The first chassis was assembled in June 2011, and the first vehicle completed in August. Gary Paffett completed the car’s first tests at the Lausitzring in early September. On 1st March 2012, the DTM cars of all three participating manufacturers were homologated by the German Motor Sports Association (DMSB), so no further major developments were permitted after that.

The DTM Mercedes AMG C-Coupé has been designed to a new, improved safety concept featuring an innovative safety cell at its core. This includes an optimised carbon fibre monocoque and a roll cage made of high strength steel. In order to improve protection for the driver in an accident, all safety-related components such as the fire extinguishing system and fuel tank are incorporated into the carbon fibre chassis. In addition, each vehicle has six energy absorbing crash structures to provide additional protection for the driver to front, rear and sides. These carbonfibre crash elements (front and rear: 61cm, side: 30cm) gradually absorb the energy in an impact so that the driver is not subjected to excessive deceleration forces. At the same time, other components dissipate the forces in a controlled manner. 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.

The new monocoque is one of some 50 standard components used by all three manufacturers in the DTM. Among other standard components are: brakes, gearbox, drive shaft, the new paddle gear change, fuel tank and rear wing. Costs can be reduced in this way without limiting scope for development of the aerodynamics, chassis and engine. As a result, the manufacturers can demonstrate technical expertise yet simultaneously deliver cost savings. Standard parts comprise around five percent of the car’s components.
