Mercedes-Benz CLS 63 AMG
21st November, 2010
Exciting design, ultimate performance and groundbreaking efficiency:
this is what the new Mercedes-Benz CLS 63 AMG is all about. The top-of-the-range version of the four-door coupé is
equipped with the newly developed AMG V8 biturbo engine, featuring a peak output of up to 410 kW (557 hp) and 800
Nm of torque, as well as the AMG SPEEDSHIFT MCT 7-speed sports transmission. On top of this, the vehicle's fuel
consumption of 9.9 litres per 100 km (NEDC) represents an improvement of 32 per cent compared with the previous
model (all figures provisional).
The combination of an AMG RIDE CONTROL sports suspension with electronically controlled damping system and new
front axle, newly developed electromechanical AMG sports parameter steering, and also optional AMG ceramic
high-performance composite braking system, is synonymous with maximum driving dynamics. Visually, the CLS 63 AMG
impresses with its 'athletic' appearance and distinctive exterior and interior design. The model's standard
specification also includes innovative LED High Performance headlamps.
"The new CLS 63 AMG continues the success story of the previous models, the CLS 55 AMG and CLS 63 AMG, which
have delighted our customers all around the world since 2004", according to Ola Källenius, Head of
Mercedes-AMG GmbH. "The CLS 63 AMG is a unique high-performance car – it sets new standards in design,
performance and efficiency."
Like the S 63 AMG and CL 63 AMG, drivers of the CLS 63 AMG will benefit from an eight-cylinder powerhouse,
designated internally as the M 157: the new AMG 5.5-litre V8 biturbo engine boasts a combination of innovative
high-tech components which, in addition to spray-guided direct petrol injection with piezo injectors, also include
a full aluminium crankcase, four-valve technology with camshaft adjustment, air/water intercooling, generator
management and stop/start system. With a displacement of 5,461 cc, the eight-cylinder engine develops a peak
output of 386 kW (525 hp) and torque of 700 Nm. In conjunction with the AMG Performance package, these figures
increase to 410 kW (557 hp) and 800 Nm. Both variants of the CLS 63 AMG achieve exceptional performance:
acceleration from zero to 100 km/h takes 4.4 and 4.3 seconds respectively, and the top speed is 250 km/h
The major difference between both power units is the increase in the maximum charge-air pressure from 1.0 to
1.3 bar. In addition, the CLS 63 AMG with the AMG Performance package features a special high-quality carbon fibre
Quantum leap: fuel consumption reduced by 32 per cent
Despite a significant performance increase compared with the previous model, which had a naturally aspirated
AMG 6.2-litre V8 engine producing 378 kW (514 hp) and 630 Nm of torque, the new CLS 63 AMG is some 4.6 litres, or
32 per cent, more economical – which represents a quantum leap forward. The NEDC fuel consumption of 9.9 litres
per 100 km equates to a CO2 output of 232 g/km. Thanks to these figures, the new V8 Coupé from AMG not only
undercuts all of its direct competitors in the small but refined four-door high-performance coupé segment, but is
also more fuel efficient than significantly lower-powered vehicles. Both performance variants have identical fuel
consumption and CO2 figures.

Exclusive: AMG SPEEDSHIFT MCT 7-speed sports transmission
A major contribution towards achieving the unrivalled consumption figures has been made by the AMG SPEEDSHIFT
MCT 7-speed sports transmission, a component used exclusively at Mercedes-AMG. Unlike a conventional automatic
transmission, the MCT transmission does away with the torque converter; instead, it makes use of a compact, wet
start-up clutch. Also fitted as standard equipment is the stop/start function: it is permanently active in the
transmission's Controlled Efficiency ("C") mode, and switches the eight-cylinder engine off when the car comes
to a stop. At the same time, "C" mode also means a "soft" accelerator response set-up with convenient and early
gearshifts; moving off generally takes place in second gear. A green "ECO" symbol in the AMG instrument cluster
shows the driver that the stop/start function is active.
The engine and transmission come across as much more agile in the "S" (Sport), "S+" (Sport plus) and "M"
(Manual) modes; in addition, the stop/start function is switched off. In "S" and "M" modes, the engine
management system partially suppresses the cylinders: interrupting ignition and injection under full load leads
to even faster gearshifts than before. The highly emotional vocals are an appealing side effect of this
lightning-fast process. An automatic double-declutching function and RACE START function are also included as
Autonomously developed AMG RIDE CONTROL sports suspension
The suspension, steering and braking system of the new CLS 63 AMG complement the high-tech drive system
perfectly. The AMG RIDE CONTROL sports suspension, with steel suspension struts on the front axle and air
suspension struts on the rear axle, as well as automatic level control, is enhanced further by an electronically
controlled damping system; it automatically adjusts the damping characteristics depending on the driving
conditions and reduces the roll angle of the body. The result: lightning-fast adjustment between optimum driving
comfort and the best possible agility. The driver can switch between the three suspension modes of "Comfort",
"Sport" and "Sport plus" at the press of a button.
The autonomously developed front axle, with a track width which is 24 mm wider, is the perfect match for the
newly developed electromechanical AMG sports parameter steering. It not only features variable power assistance
which adapts according to the suspension mode, but also contributes towards reducing fuel consumption by up to
0.3 litre (7 g CO2) in the ECE fuel cycle, since the steering assistance system only draws power when the
vehicle is actually being steered. The 3-stage ESP® also has individual setting options – thereby providing a
definite advantage when it comes to combining driving pleasure with absolute driving safety.
AMG ceramic high-performance composite braking system available as an option
Perfect deceleration even when driving extremely briskly is ensured by the AMG high-performance braking system
with 360 mm, internally ventilated and perforated brake discs all-round. Particularly resistant, motor
sports-tested composite technology is used on the front axle. The optional AMG ceramic high-performance composite
braking system with yet larger brake discs guarantees an even higher level of braking performance as well as
lower unsprung masses. Good contact with the road, meanwhile, is provided courtesy of the titanium grey-painted,
high-sheen AMG light-alloy wheels featuring a new triple-spoke design and fitted with 255/35 R 19 tyres on the
front and 285/30 R 19 tyres on the rear.
Intelligent lightweight construction: making a significant contribution to efficiency
The highest level of engineering is also reflected in the body of the new CLS 63 AMG: the intelligent
lightweight construction makes a significant contribution towards addressing the classic conflicting goals of
low weight and high strength. Like the SLS AMG, the CLS 63 AMG is also fitted with doors featuring a full
aluminium construction. They consist of deep-drawn aluminium panels with extruded sections, and are around 24 kg
lighter compared with conventional steel doors. In addition, the bonnet, front guards, boot lid, parcel shelf,
various support sections as well as major parts of the chassis and engine are all made from aluminium too.
Light-years ahead: LED High Performance headlamps as standard
The CLS 63 AMG is the first passenger car in the world to offer LED High Performance headlamps, which combine
the exciting colour elements of LED technology – similar to those of daytime running lamps – with the performance,
functionality and energy efficiency of today's bi-xenon generation. Fitted as standard, for the first time ever
this new light system provides the Intelligent Light System already proven in Mercedes models fitted with bi-xenon
headlamps in combination with LED technology. The headlamps, with their 71 LED lamps in total, underline the
unmistakable appearance of the CLS 63 AMG. The light specialists from Mercedes-Benz have for the first time been
able to use LED technology in the Adaptive Highbeam Assist, resulting in an entirely new level of safety when
driving at night.
In contrast to the first vehicles equipped with LED headlamps, no compromises are now necessary with respect
to the functionality and performance of the lighting technology. There are further arguments for the new,
LED-based lighting technology: the average operating life of an LED is around 10,000 hours, around five times
longer than that of a xenon light; moreover, LED headlamps most closely approximate the colour temperature of
daylight. This means that LED light is in keeping with normal human perception patterns. Studies have shown that
the closer the colour of artificial light comes to daylight, the less strain there is on the eyes. With a colour
temperature of 5500 kelvin, LED light is closer to daylight (6500 K) than xenon light (4200 K). The LED daytime
driving lights specific to AMG are also presented in two characteristic light strips integrated into the AMG
<>Exterior design inspired by the SLS AMG>
When viewed from the front, the new CLS 63 AMG evokes associations with the SLS AMG – the radiator grille in
particular, with its large Mercedes star and wing-shaped horizontal slats, appears to have been inspired by the
"gullwing". The top-of-the-range AMG model distinguishes itself from the other CLS variants with its distinctive
bonnet, wider mudguards with "V8 BITURBO" logo and a specific AMG front apron with black painted cross member.
Eye-catching features at the rear include the diffuser insert, the AMG spoiler lip on the boot lid, the AMG
sports exhaust system with dual twin chrome tailpipes, and - as also featured on the SLS AMG - integrated rear
foglamp. The AMG bodystyling perfectly matches the typical CLS outline, which is essentially characterised by
the elegantly long proportions, the lateral dropping line and the muscular sports car-like shoulder line above
the rear axle.
Exclusive atmosphere in the interior
This philosophy also continues through consistently into the interior. All of the AMG-specific design and
appointment features ideally supplement the redesigned CLS interior. The wrap-around effect in the cockpit,
with its high line which sweeps from the driver's door over the instrument panel support and across to the
front passenger door, is generously flanked by high-quality trim elements – available in black piano lacquer
as standard in the top-of-the-range AMG model. Quality materials and workmanship meet the very highest of
standards and help to guarantee a particularly exclusive atmosphere.
The extensive range of standard appointments also includes AMG sports seats in nappa leather, a new
three-spoke AMG Performance steering wheel with aluminium shift paddles and flattened top and bottom sections,
and the AMG DRIVE UNIT with compact E-SELECT selector lever.
New driving assistance systems: greater safety
More than a dozen driving assistance systems on the new CLS help to prevent traffic accidents and reduce
the severity of an accident. The Active Blind Spot Assist and the Active Lane Keeping Assist are new.
Active Blind Spot Assist warns the driver if it detects - with the assistance of short-range radar
sensors - that there is a danger of collision if the vehicle is about to change lanes. Should the driver
ignore the warnings and come dangerously close to the vehicle in the next lane, Active Blind Spot Assist
will intervene. By applying braking force to the wheels on the opposite side of the vehicle via the
Electronic Stability Programme ESP®, a yaw movement is made which counteracts the collision course.
Active Lane Keeping Assist is now also linked to the ESP® for the first time. This system kicks into
action if the driver inadvertently drifts over a solid line to the right or left of a lane. In this case,
Active Lane Keeping Assist brakes the opposite wheels and thereby prevents the vehicle from crossing the
line. A display on the instrument cluster warns the driver at the same time. If broken lane markings are
crossed, the system controls an electric pulse generator in the steering wheel which generates vibrations
for a short time – a discreet but highly effective cue to countersteer immediately. Before the braking
system intervenes, the steering wheel always vibrates to provide a warning.

Specially designed "Edition 1"
Also available is the special limited "Edition 1" version of the CLS 63 AMG. Finished in the new
manganite grey SHAPE matt paint, the "Edition 1" features a host of specially designed high-quality
interior details. On opening the doors, the first items to catch the eye are the AMG sports seats:
the "corteccia pearl" designo leather is characterised by a shimmering metallic surface finish.
The roof lining, A, B and C-pillars, as well as the sunblinds, are finished in anthracite Alcantara®,
while carbon fibre/black piano lacquer AMG trim elements help to give the interior a functional
atmosphere. Also making a perfect match for the designo leather seats are the designo floormats in black
velour, featuring designo badge and designo leather insert in "corteccia pearl".
