The new DTM Safety Car: The most powerful C-class of all time

A further highlight of the 2012 DTM season in addition to the spectacular new Mercedes-AMG C-Coupe will be the DTM Safety Car - right from the off, C 63 AMG Coupe Black Series will be providing the necessary safety for the world's most popular touring car series. With a
maximum output of 380 kw (517 hp), this two-seater is the most powerful C-class of all time. The German Touring Car Masters (DTM) gets underway at the Hockenheimring on April 29, 2012.

The Safety Car is deployed under the direction of the German Motorsport Association (DMSB), which is responsible for implementing safety measures, ensuring compliance with safety standards and discharging the attendant official sporting functions in accordance with the DTM rules. The C 63 AMG Coupe Black Series Safety Car driven by racing driver Jurgen Kastenholz (44) is intended to ensure maximum safety for racing drivers, spectators and track marshals in case of dangerous situations, such as extreme weather conditions, accidents or other incidents. In response to a radio message from the race organisers, the Safety Car enters the track and leads the DTM field around the circuit until normal racing can be resumed.

The most powerful C-class of all time stands for spectacular design, technology transfer from the field of motorsport and driving dynamics of the very highest calibre. As such, the C 63 AMG Coupe Black Series only required modification to a few points of detail for deployment as the DTM Safety Car. The most  striking feature distinguishing it from the series production version is the aerodynamically optimised light bar on the roof. Energy-efficient, fast-response LEDs in green and orange keep the DTM racing drivers informed of the current situation.
> Green: The two central green lights on the front and rear are always active when the C 63 AMG Coupe Black Series enters the field at the beginning of a Safety Car phase. Continuous green is the signal for all DTM drivers to overtake the Safety Car
> Orange: As soon as the Safety Car is in position in front of all DTM vehicles, the green LEDs are switched off and the orange LEDs are activated. The flashing orange lights at the outer ends of the light bar indicate that overtaking is absolutely prohibited.

The stroboscope-like flashing LED lights on the front and rear remain active throughout the Safety Car phase. The license plate with Safety Car lettering which is illuminated by LEDs on the boot lid provides for better visibility in poor weather.

Engine, power transmission, chassis, suspension and brake system corresponding to series production variant
The AMG 6.3-litre V8 engine corresponds to the series-production engine with a maximum output of 380 kw (517 hp) and maximum torque of 620 nm it even tops the roughly 377 kw (500 hp) V8 engine in the Mercedes-AMG C-Coupe which is being used in the DTM. The high-speed naturally aspirated engine enables acceleration to 100 km/h from a standing start in 4.2 seconds and a top speed of 300 km/h (electronically limited). With the spectators at the race track and the TV audience in mind, the C 63 AMG Coupe Black Series Safety Car is fitted with a modified AMG sports exhaust system. The special rear silencer guarantees a distinctive AMG V8 sound.

Engine cooling, power transmission, chassis and suspension, brake system – these areas have been honed to perfection and did not require any modification. The AMG SpeedShift MCT 7-speed sports transmission with four drive programmes, double-declutching function and Race Start guarantees direct and fast gear-shifting. As is customary in motorsport and typical for a Black Series model, the AMG sports suspension is designed as a coil-over suspension. It covers a broad range of adjustment options for an individual race track set-up. The standard-fit AMG rear-axle differential lock with locking effect in acceleration and deceleration mode combines with the 3-stage ESP for reliable traction. The AMG high-performance braking system featuring motorsport-tested compound brake disks at the front offers extremely short stopping distances and fade-resistant deceleration performance.

Optional equipment from the AMG Performance Studio
The C 63 AMG Coupe Black Series DTM Safety Car is equipped with the AMG Track package, the AMG Aerodynamics package, the AMG Exterior Carbon-Fibre package and forged AMG light-alloy wheels. The AMG Track package comprises active rear axle gear cooling and sports tyres. The radiator is positioned in front of the diffuser insert in the rear apron, where it effectively takes in the air stream. The specially developed Dunlop Sport Maxx Race sports tyres in size 255/35 R 19 at the front and 285/30 R 19 at the rear are fitted on forged AMG wheels which are painted matt black with a high-sheen rim flange.

The AMG Aerodynamics package includes so-called flics and a functionally designed genuine carbon-fibre front splitter on the front apron, plus a fixed carbon-fibre rear aerofoil with adjustable blade. All three components provide the vehicle with a sharper profile while optimising its aerodynamic balance. The AMG Exterior Carbon-Fibre package covers exterior mirror housings, the inserts in the side sill panels and a diffuser insert in genuine carbon fibre. All optional equipment items come from the AMG Performance Studio and are available ex-factory for every C 63 AMG Coupe Black Series.

Functional race-track atmosphere in the interior
The interior also corresponds to the series production model, with a few exceptions. The two AMG sports bucket seats ensure optimum lateral support for driver and co-driver. In view of the intended deployment on the race track, four-point seat belts are used. Optimum control of the vehicle is guaranteed by the AMG Performance steering wheel in nappa leather/Dinamica with flattened top and bottom rim sections and aluminium gearshift paddles.

AMG carbon-fibre trim featuring the 'AMG Black Series' logo underscores the functional race-track atmosphere. For communication with the race organisers, the Safety Car is equipped with a two-way radio system and TV monitor. The camera located next to the rear license plate provides the co-driver with a view of the DTM cars following the Safety Car. Under the monitor there are four buttons in blue, green, orange and silver for operating the light bar, the stroboscope-type flashing LED lights and the horn.
