Mercedes-Benz C63 AMG being used for the 2011 DTM season comes with the AMG 6.3-litre V8 engine has an exceptionally high output of 358 kW (487 hp) and a peak torque of 600 Nm. The increase in output versus the standard 336 kW (457 hp) engine is due to the AMG Performance Package, which is optionally available for any C63 AMG model and enables the car to accelerate from 0 to 100 km/h in 4.3 seconds (Estate 4.4 seconds). For the AMG Performance Package the engine specialists have placed their trust in a technology transfer from the Mercedes-Benz SLS AMG: the forged pistons, connecting rods and lightweight crankshaft have been adopted from the gull-wing model. The lower inertia of the three-kilogram lighter components allows the naturally aspirated eight-cylinder engine to rev freely and respond even more promptly. Distinguishing features of the Performance Package include the variable intake manifold painted in titanium grey and the AMG high-performance braking system with compound brake discs at the front axle.
New equipment includes the innovative AMG SPEEDSHIFT MCT 7-speed sports transmission, which incorporates a wet start-up clutch and four transmission modes as well as double-declutching and RACE START functions for optimum driving dynamics. Distinguishing features of the current model include the aluminium bonnet with modified powerdomes, the new radiator grille, the new headlamps, the new AMG rear apron with a distinctive black diffuser insert and active rear-axle cooling. To optimise radiator inflow, the AMG front apron on the DTM Safety Car features enlarged openings and side air outlets, while the AMG carbon-fibre spoiler lip on the boot lid reduces lift at high track speeds. In keeping with this design, the DTM Safety Car also sports AMG carbon-fibre exterior mirrors.
The Mercedes-Benz C63 AMG DTM Safety Car is shod with multi-spoke AMG light-alloy wheels painted in matt black with a high-sheen rim flange, 235/35 R 19 front tyres and 255/30 R 19 rear tyres.
