A new top V8 model is making its debut in Geneva in the form of the CLK 63
The 100% AMG-developed 6.3-litre V8 engine under the bonnet
promises a truly memorable driving experience. Available in both Coupé and
Cabriolet guise, the CLK 63 AMG eclipses the power and torque figures for
any other model in this segment with a maximum output of 354 kW/481 hp
and 630 newton metres of peak torque.
Compared to its predecessor, the CLK
55 AMG, power has been upped by 84 kW/114 hp (+31 percent) and torque by
120 newton metres (+23 percent) in the CLK 63 AMG. With new AMG high-
performance composite brakes, a new AMG sports suspension, new AMG 18-
inch light-alloy wheels plus exclusive and dynamic standard appointments,
the new CLK 63 AMG is the sportiest and most elite CLK to date.
The new AMG 6.3-litre V8 engine delivers truly explosive performance: the
CLK 63 AMG Coupé sprints from standstill to 100 km/h in 4.6 seconds
(predecessor: 5.2 s), with the Cabriolet taking 4.7 seconds (predecessor: 5.4 s).
The electronically limited maximum speed is 250 km/h. The majestic power
delivery of the Mercedes-AMG V8 engine permits either electrifying acceleration
or relaxed cruising in a high gear with ample power reserves. The new 6.3-litre
V8 engine from AMG is the first in the world to combine the high-revving concept
with a large displacement. Developed exclusively by AMG, this high-performance
engine delivers 20 percent more torque than comparable naturally aspirated
engines with a similar power rating.
AMG V8 naturally aspirated engine with an array of high-tech features
Made entirely from high-strength aluminium, the V8 naturally aspirated 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 superlative cylinder charging.
The use of bucket tappets in the cylinder heads paves the way for a stiff valve train and therefore
high engine 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.
This unique combination of a fast-running design and a large displacement
achieves the best of both worlds: exhilarating high-revving flexibility
accompanied by high pulling power at low engine speeds. The decidedly sporty
character of the CLK 63 AMG manifests itself in the form of tremendous agility
and dynamic responsiveness 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 5000 rpm.
The new AMG V8 unit promises dynamic acceleration, instantaneous pickup and
sheer driving pleasure at the highest level. With its new, sporty AMG soundtrack
which was fine-tuned during an extensive series of tests, the eight-cylinder
powerpack from Affalterbach offers all the spine-tingling excitement of a high-
revving V8 naturally aspirated engine that makes its presence both heard and felt
at any engine speed.
New AMG SPEEDSHIFT 7G-TRONIC promises extra dynamism
The new AMG SPEEDSHIFT 7G-TRONIC transmission is the perfect complement
to the dynamic power delivery and can be operated using the AMG shift paddles
on the steering wheel. The seven-speed automatic transmission caters effortlessly
for both a dynamic driving style and a more comfort-orientated approach. Three
shift modes specially configured for the performance characteristics of the AMG
V8 engine enable its tremendous power to be harnessed to best effect. Selectable
using a switch in the centre console, the shift modes in the CLK 63 AMG - "S"
(Sport), "C" (Comfort) and "M" (Manual) – differ in terms of their shift
characteristics and shift speeds.
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. Plus, AMG
SPEEDSHIFT does not automatically execute an upshift when it reaches the
engine speed limit in manual mode either, which allows drivers with a
particularly sporty streak to make even better use of the power at their disposal.
As the rev speed approaches the lower limit, the transmission automatically
changes down a gear.
AMG 18-inch light-alloy wheels and new AMG composite brakes
Equipped with a retuned AMG sports suspension, high-sheen AMG 18-inch light-
alloy wheels featuring a titanium grey painted finish and new five-spoke styling,
as well as wide-base tyres (size 225/40 at the front and 255/35 at the rear), the
CLK 63 AMG has precisely what it takes to deliver sporty handling and high-speed
cornering. New AMG high-performance composite brakes can be found at the front
wheels, with internally ventilated brake discs providing sure stopping power at
Powerful, harmonious AMG bodystyling
The CLK 63 AMG makes no secret of the fact that it is a range-topping sports
model: the powerful AMG bodystyling injects even more dynamism into the
already exciting design. The new front apron with its bolder lines, air outlets at
the sides and integral fog lamps, the side skirts and the rear apron together
produce an overall look that is bristling with character. The "6.3 AMG" lettering
adorning the front wings adds further lustre. The spoiler lip on the boot lid
reduces the lift acting at the rear axle by over 50 percent. At the rear of the
CLK 63 AMG Coupé, the AMG sports exhaust system with two sets of chromed
twin oval tailpipes provides both a visual highlight and an acoustic highlight with
its sonorous V8 sound.
The CLK 63 AMG Cabriolet is fitted with an AMG sports
exhaust system ending in a single chromed twin oval tailpipe.
Exclusive leather interior and high-class appointments
Sportiness and exclusivity are the predominant themes inside both V8 models
too. AMG door sill panels, special AMG aluminium trim elements with decorative
chrome strips and the new AMG instrument cluster with a 320-km/h speedometer
dial create a unique ambience without compromising at all on practicality. Also
new is the AMG main menu in the instrument cluster, which displays the
currently engaged gear and recommended upshifts in Manual mode, plus either
the engine oil temperature or the battery voltage as well as the RACETIMER. The
new RACETIMER 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.
The new silver-coloured aluminium AMG shift
paddles on the AMG ergonomic sports steering wheel are particularly eye-
catching. The electrically adjustable AMG multicontour sports seats are heated
and come upholstered in exclusive nappa leather with an attractive cross-piping
design. The market launch of the new CLK 63 AMG is due to commence in the
second quarter of 2006.
