Mercedes-Benz C 63 AMG Estate
The successful Mercedes-Benz C 63 AMG is now more attractive than ever:
the modified design of the top-of-the-range C-Class model is complemented by numerous enhancements to its
technology which deliver even more driving enjoyment while significantly improving fuel consumption.
____________________________________________________________________
____________________________________________________________________
The introduction of the AMG SPEEDSHIFT MCT 7-speed sports transmission with the "Controlled Efficiency" mode as standard along with a new power steering pump
help to improve the combined NEDC fuel consumption by about ten percent to 23.5 mpg (Estate: 22.9 mpg). The output of the AMG 6.3-litre V8 engine is unchanged
at 457 hp and can be increased to a maximum of 487 hp with the optional AMG Performance package. Agility, grip and ride comfort have been enhanced as a result
of numerous measures to optimise the AMG sports suspension. New assistance systems and a new generation of telematics with internet access increase both safety
and comfort.
The latest 2011 generation of the C 63 AMGis now more dynamic and athletic than ever. Thanks to its new radiator grille with a large Mercedes star and a wing-type
transverse louvre, as well as a new AMG front apron with a lower cross member painted in high-gloss black, special AMG daytime running lights and side air outlets,
the front section recalls the look of the SL 63 AMG high-performance roadster. The new bonnet with its modified powerdomes is now made of aluminium.
New clear-lens headlamps emphasise the car's distinctive, self-confident presence and the Intelligent Light System (ILS) Â is fitted as standard. The wide front wings
with the "6.3 AMG" legend and the new 5 twin-spoke AMG light-alloy wheels which are painted in titanium grey and have a high-sheen finish dominate the side view.
Good contact with the road is provided by the wide 235/40 R 18 and 255/35 R 18 tyres at front and rear respectively.

The rear view of the C 63 AMGalso evokes the SL 63 AMG: the new AMG rear apron has a distinctive, black diffuser insert with three pronounced diffuser fins.
The two chromed twin tailpipes of the AMG sports exhaust system are as pleasing to the ear as they are to the eye.
Under the skin, too, the top C-Class model boasts a wealth of new technology including the AMGSPEEDSHIFT MCT 7-speed sports transmission. Â Rather than using a
torque converter, this innovative transmission has a wet start-off clutch which allows it to deliver a much more efficient, agile and direct response.
Fuel consumption and emissions have been reduced significantly thanks to the "Comfort" mode and a new power steering pump: at 23.5 mpg (Estate: 22.9 mpg) the
combined NEDC fuel consumption of the C 63 AMG sees about a ten per cent improvement over that of the previous model. CO2 emissions figure is now 280
(Estate: 288) grams per kilometre. Both power variants have identical fuel consumption and emission figures.

TheAMGSPEEDSHIFT MCT 7-speed sports transmission impresses with its exceptional flexibility: with four driving modes as well as double-declutching and
RACE START functions it is as compatible with a relaxed, fuel-saving driving style as it is with high-speed laps on a closed racing circuit and extremely dynamic
overtaking manoeuvres. The Comfort "C" mode is programmed to provide early, comfortable upshifts while maintaining the lowest possible engine speed to help the
driver keep fuel consumption down. The "S", "S+" and "M" modes deliver increased agility through fast, responsive gear changes and higher revs. Gear changes in
the "S+" and "M" modes take just 100 milliseconds.
The naturally aspirated eight-cylinder engine with its large displacement of 6208 cc develops 457 hp at 6800 rpm and attains a peak torque of 600 newton metres
at 5000 rpm. A look at the performance figures confirms that the new C 63 AMGretains its predecessor's position as the top performing model in its segment:
acceleration from standstill to 62 mph in just 4.5 seconds (Estate: 4.6 s) while the top speed is 155 mph (electronically limited).

Even more dynamic performance is available with the optional AMG Performance package: this offers 487 hp and allows a 0-62 mph acceleration time of 4.4 seconds
(Estate: 4.5 s). The Mercedes-AMG engine experts have achieved this increase in output thanks to a technology transfer from the SLS AMG: the forged pistons,
connecting rods and the lightweight crankshaft all come from the gullwing model's engine. The reduced mass inertia of the components - which are three kilograms
lighter than those of the standard version - allows the naturally aspirated eight-cylinder engine to rev up with even greater ease and agility. Models equipped with
the performance package can be identified by the variable intake manifold painted in titanium grey under the bonnet, the AMG high-performance braking system
with composite front discs and red painted brake callipers all round, the carbon-fibre spoiler lip on the boot lid (Saloon) and the AMG performance steering wheel in
nappa leather with an Alcantara® grip area.
TheAMGsports suspension with a special front axle, reinforced rear axle and wider track all round has undergone thorough modification; the driver benefits from
this in two ways as the C 63 AMG now offers greater driving enjoyment and ride comfort at all times. The new, stiffer elastokinematics, the revised axle kinematics
with more negative camber all round and the new rear-axle anti-roll bar with a larger cross-section result in higher agility and greater lateral acceleration.
But driving dynamics is not the only area in which progress has been made: new spring and damper rates have optimised both the responsiveness of the suspension
as well as the road roar and tyre vibration characteristics.

TheAMGspeed-sensitive sports steering with a direct ratio (13.5 : 1) has a newly developed power-steering pump which plays a decisive role in reducing the fuel
consumption. This is because the power assistance for the steering only requires energy when the driver is actually making steering movements.
Reliable deceleration at all times is ensured by the AMG high-performance braking
system with internally ventilated and perforated discs all round.
Even a quick glance at the interior of the C 63 AMGreveals the considerable progress which has been made: the completely new dashboard design with an integrated
screen impresses with its particularly attractive appearance and the superior quality of the details which immediately bring the new CLS 63 AMG to mind. The new,
all-colour, three-dimensional TFT display in the middle of the redesigned speedometer welcomes the driver by showing the AMG logo. The new three-spoke AMG
performance steering wheel - another feature adopted from the CLS 63 AMG - which is trimmed in nappa leather and features a metallic trim element has flattened
top and bottom sections as well as grip areas which are specially shaped and trimmed in perforated leather for perfect steering control. Aluminium shift paddles
allow manual gear selection.

Fine trim elements in brushed dark aluminium are to be found on the dashboard and doors. Situated in the centre console, is the enhanced high-gloss black piano
lacquer trim elements and the new rotary control for selecting the transmission modes C, S, S+, M and RACESTART. The special AMG sports seats with integral head
restraints and adaptive backrests are upholstered in nappa leather.
