Mercedes-Benz C63 AMG DTM Safety Car
The new C 63 AMG is being used as the Safety Car for the 2011 DTM season. The V8 Sports Saloon only had to be modified slightly for its demanding DTM task. Responsibility for development and production of the C 63 AMG Safety Car was entrusted to the specialists in the AMG Overall Vehicle Development department and the AMG Performance Studio.
The new C 63 AMG being used for the 2011 DTM season scales new heights in terms of design and technology: the AMG 6.3-litre V8 engine has an exceptionally high output of 358 kW (480 hp) and a peak torque of 600 Nm. The increase in output versus the standard 336 kW (451 hp) engine is due to the AMG Performance Package, which is optionally available for any C 63 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 adjustable coil-over suspension together with the differential lock and the 3-stage ESP® ensures a high level of agility and outstanding grip on the race track. The C 63 AMG 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.
The AMG high-performance braking system has been optimised for the race track: compound brake discs with six-piston brake callipers at the front axle and steel brake discs with four-piston brake callipers at the rear axle; all of the discs are internally ventilated and perforated. Meanwhile, the AMG sports exhaust system with special rear silencers produces an unmistakable AMG V8 sound.
Distinguishing features of the DTM Safety Car compared to the standard C 63 AMG include distinctive DTM Safety Car logos, the LED light bar on the roof and the stroboscopic flashing LED lights at the front and rear. A number plate illuminated with LEDs and the words "Safety Car" on the boot lid make the car easier to see in poor weather conditions. To facilitate communication with Race Control, the Safety Car is fitted with a radio system and a TV monitor. Two AMG sports bucket seats with four-point seat belts provide ideal lateral support for the driver and co-driver, while the AMG performance steering wheel in nappa leather/Alcantara with steering-wheel shift paddles assures optimum vehicle control.
Mercedes-AMG has provided the Safety Car ever since the "new" DTM's inception in 2000 and alternates with Audi from race to race. The flagship V8 C-Class model from AMG has been used in DTM since its launch in 2008. To help ensure safety on the race track in the Formula-1 World Championship, the SLS AMG is used as the Official F1TM Safety Car, while the Official F1TM Medical Car is a C 63 AMG Estate.
