The new CLK 63 AMG Black Series based on the Official F1™ Safety Car – the high-performance AMG vehicle that has been providing Formula One safety since 2006. The coupe, optimized for the racing circuit, is powered by an AMG 6.3-liter V8 with its performance boosted to 373 kW/507 hp and 630 Newton meters of torque. Top-rank handling is assured by the sophisticated AMG threaded suspension with 19-inch AMG forged wheels, new steering and the generously dimensioned AMG high-performance brake system with its composite disks. Visually, too, the CLK 63 AMG Black Series clearly shows its descent from the Official F1™ Safety Car: its striking front apron with large cooling intakes, flared wheel arches, diffusor-type rear apron and carbon-fiber airflow breakaway edge, all demonstrate the car’s sporting and pur sang pedigree.

Transition from motorsport in its purest form: the new CLK 63 AMG Black Series is derived from the official F1™ safety car – the AMG high-performance vehicle that has been the sentinel of safety at Formula 1 races since 2006. Carefully honed for the race track, the coupé is powered by an uprated AMG 6.3-litre V8 engine delivering 373 kW/507 hp and 630 Newton metres of torque. Dynamic handling of the highest order is assured by the newly designed axles, the painstakingly developed AMG sports suspension featuring spring and shock absorber units with adjustable coil springs and 19-inch AMG forged wheels, the new steering and the thicker AMG high-performance composite brakes. The affinity of the CLK 63 AMG Black Series to the official F1™ safety car is clearly obvious from its looks too: its striking front apron with large air intakes, flared wings, diffusor-look rear apron and carbon-fibre spoiler lip all demonstrate the car’s sporting, puristic pedigree.

The new CLK 63 AMG Black Series draws its technical and visual inspiration from the official F1™ safety car, meaning that it will appeal to all sports-car enthusiasts looking for enhanced race-track capability. Thanks to an extra 19 kW/26 hp of output, the CLK 63 AMG Black Series races from standstill to 100 km/h in 4.3 seconds, making it 0.3 seconds faster than the standard 354-kW/481-hp model. The top speed is 300 km/h (electronically limited).

Mercedes-AMG engineers achieved the increase in power to 373 kW/507 hp by completely overhauling the intake and exhaust systems. The high-revving, naturally aspirated AMG engine with a displacement of 6208 cc is supplied with fresh air via enlarged intake ducts. The new AMG sports exhaust system with full-length twin pipes features brand new silencers and a lower exhaust backpressure. Not only does this have a beneficial effect on output, it has an impact on the acoustics too by producing that irresistible, unmistakable AMG V8 sound. Together with a reprogrammed engine management unit, these measures not only ensure a more efficient charge cycle, they enable the V8 power unit to respond to the accelerator with even greater alacrity. It goes without saying that the CLK 63 AMG Black Series complies with the EU 4 emissions standard as well as the specific requirements of the US market.

Naturally aspirated AMG V8 engine with an array of high-tech features

Made entirely from high-strength aluminium, the naturally aspirated V8 engine is packed with a wealth of fascinating racetrack technology that reflects AMG’s rich motorsport heritage. The vertical arrangement of the intake and exhaust ports together with the sophisticated new variable intake manifold featuring two integral throttle flaps results in perfect cylinder charging. The use of bucket tappets in the cylinder heads paves the way for an unyielding valve train and therefore high rev speeds. Variable camshaft adjustment, an extra-rigid closed-deck crankcase and cylinder walls with a revolutionary new LDS coating are further attributes of this ultra-sophisticated V8 engine made by Mercedes-AMG.

The electronically controlled fuel supply operates with a system pressure of between 3.8 and 5.0 bar, depending on current requirements. The fuel pressure is adjusted instantaneously to match the power demands and outside temperature. The engine electronics translate the command from the accelerator into a corresponding specified target pressure in a matter of milliseconds. This variable control guarantees spontaneous response combined with sporty overrun characteristics throughout the full spectrum of engine loads and rev speeds.

This unique combination of a high-revving concept and a large displacement achieves the best of both worlds: exhilarating, free-revving flexibility accompanied by high pulling power at low engine speeds. The decidedly sporty character of the CLK 63 AMG Black Series manifests itself in the form of tremendous agility across all engine speed ranges. The new AMG V8 delivers 500 Newton metres of torque to the crankshaft as low down as 2000 rpm, while the maximum of 630 Newton metres is on tap at 5250 rpm. In the AMG engine manufacturing facility, each engine is traditionally built according to the "One man, one engine" philosophy. Every AMG V8 engine is hand-assembled from start to finish by a single engineer in accordance with the strictest quality standards– as verified by the engineer’s signature on the AMG engine plate.

Seven gears with a distinctly sporting feel

Power is transmitted to the wheels through the AMG SPEEDSHIFT 7G-TRONIC. Compared to the standard CLK 63 AMG, the rear-axle final drive ratio of this puristic special-edition series has been shortened by about six per cent for even greater agility when accelerating at any speed. The driver can move between the seven gears by using the AMG aluminium gearshift paddles on the steering wheel, while an indicator in the AMG instrument cluster shows the gear currently selected at any given time.

In the manual "M" driving mode, gear changes are executed around 20 per cent faster than in "S". Moreover, in the manual "M" mode the driver can truly harness the immense pulling power generated by the V8 engine, as there is no automatic downshift under full throttle or during kickdown; the transmission remains in the selected gear. AMG SPEEDSHIFT does not automatically shift up a gear when it reaches the engine speed limit in manual mode either to enhance the vehicle’s dynamic performance on the race track. A visual icon appears in the AMG main menu when it is recommended to change up a gear.

Optimised cooling for peerless stamina

Motor racing sets the tone for the looks of the CLK 63 AMG Black Series too. The redesigned front section is directly descended from the official F1™ safety car, and its generously proportioned air intakes provide a visual hint of the sophisticated cooling measures at work. For greater resilience under extreme operating conditions, not only is there a larger main radiator and an optimised cooler for the power steering, an additional transmission oil cooler can also be found in the front-left wheel arch. The engine oil cooler is located in the right wheel arch. The cooling measures are rounded off by optimised air ducts with side outlets made from genuine carbon fibre in front of the front wheels. The front wings are made entirely of plastic. The "6.3 AMG" badge on their flanks announces the exceptional power of the naturally aspirated V8 under the bonnet. Restyled side sill panels extend back to the broad rear wings, which are in turn connected by a newly developed rear apron. As well as carbon-fibre diffusor fins and the two twin tailpipes of the AMG sports exhaust system, the rear apron also incorporates the cooler for the rear-axle limited-slip differential, which is subject to particularly high loads when the vehicle is being raced. For this reason, it comes with a separate oil cooler with an electric pump which is activated as a function of the oil temperature. The new carbon-fibre spoiler lip on the boot lid reduces uplift at the rear axle. The AMG logo with "Black Series" lettering provides a discreet yet clear reminder of the formidable exclusiveness and race track capabilities of this high-speed AMG coupé. In addition to the above, a series of measures have been incorporated to purposefully reinforce the entire bodyshell.

Adjustable AMG sports suspension for optimum track performance

Like its counterpart in the Formula 1 World Championship, the CLK 63 AMG Black Series also has a newly developed AMG sports suspension. Featuring spring and shock absorber units with adjustable coil springs, it delivers optimum road contact and maximum precision. It allows drivers to create a personalised suspension setup for competitive driving: not only is the ride height adjustable but also the compression and rebound stages of the shock absorbers, the front-axle track and camber, as well as the rear-axle track. Both axles come with newly developed components, such as the spring links, wheel carriers and the thrust, camber and torque arms, as well as completely reworked elastokinematics including the strut tower bearings for the front suspension . Compared to the series-production CLK 63 AMG, the Black Series has over 75 millimetres more track width at the front and an extra 66 millimetres at the rear. Extra rigidity to handle increased lateral dynamics is provided by the strut tower braces in the engine compartment and the boot as well as the supplementary diagonal braces in the front section of the vehicle. On the rear axle, a multi-plate limited-slip differential ensures optimum traction, with a 30 per cent locking effect under throttle and 10 per cent when overrunning. Acceleration skid control (ASR) and the Electronic Stability Program ESP® have been recalibrated to make allowance for the more dynamic handling.

Ultra-light forged wheels, sports tyres for a perfect grip

The wheel and tyre combination used is the perfect complement for the AMG sports suspension with its adjustable coil springs. Pirelli P Zero Corsa sports tyres size 265/30 R 19 (front) and 285/30 R 19 (rear) permit exceptional levels of grip and astonishing cornering speeds, combined with outstanding characteristics in the wet. The tyres are mounted on handsome multi-spoke forged wheels. The imposing 9.00 x 19 and 9.50 x 19 AMG light-alloy wheels are manufactured using forging technology to make them even lighter. The weight reduction results in improved response from the speed-sensitive power steering, which has also been modified for greater precision and agility.

AMG high-performance brake system with composite discs at the front

Looking through the tracery of the AMG forged wheels, you can catch a glimpse of the ventilated and perforated disc brakes. Thicker 360 x 36 mm brake discs featuring the composite technology that has been tried and tested on the race track can be found at the front wheels. Their counterparts at the rear measure 330 x 26 millimetres. Flawless deceleration, optimal metering of braking power and tremendous fade resistance are the hallmarks of the AMG high-performance brake system – even when pushed to the limit out on the track.

Interior with the functional feel of a genuine racing car

The transfer of technology from motorsport is equally evident in the interior of the CLK 63 AMG Black Series. This dedicated two-seater sports car not only dispenses with rear seats, but with its new AMG sports bucket seats (ECE version only), alluring carbon-fibre trim and black headliner, it pulses with the functional atmosphere of a true racing car – and thus documents 40 years of Mercedes-AMG motorsport history. The AMG sports bucket seats without sidebags are covered in flame-retardant nylon velour with white AMG logos. The interior is given an even classier air by carbon-fibre trim elements on the centre console and on the interior door panelling, which also features embossed AMG logos, aluminium door handles as well as black anodised trim strips. Further highlights of the centre console include the specially styled sports selector lever, the new start/stop button with its gleaming matt finish and the AMG logo with "Black Series" lettering.

The new AMG performance steering wheel is 15 millimetres smaller in diameter and comes with silver-coloured aluminium gearshift paddles. The steering wheel rim, with a diameter of 365 millimetres, is flattened on its underside to ensure that the driver of the CLK 63 AMG Black Series maintains an optimum seating position and perfect control over the vehicle at all times.

AMG instrument cluster with RACETIMER

The carbon-fibre-embedded AMG instrument cluster with a speedometer calibrated up to 320 km/h and red needles radiates an air of exclusivity paired with excellent functionality. The AMG main menu in the instrument cluster is just the thing for serious outings on the race track: it displays the gear currently engaged and recommended upshifts in Manual mode, plus either the engine oil temperature or the battery voltage, as well as the RACETIMER. This last function allows the driver to record lap times on private racing circuits, storing not only the time for the fastest lap but also the average and top speeds as well as the lap length.

Despite its race-car-like handling dynamics, the CLK 63 AMG Black Series retains all of those trademark qualities that distinguish a true Mercedes-Benz: everyday practicality, longevity, safety and quality. Just like the SLK 55 AMG Black Series before it, the new CLK 63 AMG Black Series was developed in the AMG PERFORMANCE STUDIO opened in 2006. Customer deliveries of the unlimited AMG special series are due to commence in June 2007.
