Mercedes-Benz C63 AMG
In the German Touring Car Championships (DTM) the new AMG C-Class ensures exciting motor racing at the highest level, and now its roadgoing sister model is celebrating its debut: the new C 63 AMG. Its AMG 6.3-litre V8 engine develops a peak output of 336 kW/450 hp and a maximum torque of 600 newton metres – unrivalled figures in this segment. Accordingly the C 63 AMG accelerates from zero to 100 km/h in 4.5 seconds, while its top speed is electronically limited to 250 km/h. In conjunction with an all-new front axle, speed-sensitive AMG sports steering and the new, 3-stage ESP Ò, the AMG sports suspension ensures both outstanding driving enjoyment and exemplary handling dynamics. A combination of expressive design, a decidedly sporty interior and a high level of everyday practicality makes the C 63 AMG a unique high-performance car.
With the new C 63 AMG, Mercedes-AMG GmbH is making a confident statement to mark the 40th birthday of the company. The new V8 flagship model is now the fifth generation of the AMG C-Class, whose family tree goes back to the C 36 AMG of 1993 – the very first vehicle developed as a cooperative venture between Daimler-Benz and AMG.
Merely the appearance of the C 63 AMG is impressive enough, with its wide, road-hugging stance. The new bonnet with its prominent power domes conceals the independently developed AMG 6.3-litre V8 engine, which develops a fulminating 336 kW/450 hp at 6800 rpm from a displacement of 6208 cubic centimetres. In this respect the C 63 AMG comes very close to the 470 or so horsepower delivered by the AMG C-Class racing touring car in the DTM series. This high output also benefits the power-to-weight ratio, which is a very favourable 3.6 kg/hp.
The torque developed by the AMG 6.3-litre V8 engine need fear no comparison either. The maximum of 600 newton metres at 5000 rpm is unrivalled in this class, and the torque curve is equally impressive: from 2000 to 6250 rpm the driver always has more than 500 newton metres on tap – ideal for powerful acceleration in any engine speed range.
Perfect cylinder charging is guaranteed by the vertical arrangement of the intake and exhaust ducts, as well as the magnesium variable intake manifold with two integral throttle flaps. Other high-tech features include variable camshaft adjustment, four-valve technology with bucket-type tappets, a particularly rigid aluminium crankcase of closed-deck design and the low-friction TWAS coating on the cylinder contact surfaces.
Among the particular strengths of the AMG V8 engine are outstanding responsiveness and enormous pulling power – by virtue of its large displacement, it develops over 30 percent more torque than comparable engines in this performance class. Electronically controlled fuel delivery is another reason for the outstanding agility and responsiveness to movements of the accelerator. With its sporty AMG sound, which was designed-in during a series of sophisticated trials, this eight-cylinder powerpack from Affalterbach offers the unique excitement of a fast-revving, naturally aspirated engine – an audible and immediate experience whether at low, medium or high engine speeds.
In the interests of optimal reliability, the C 63 AMG has a particularly efficient water cooling system and large engine and transmission oil coolers. Located behind the large apertures in the AMG front apron, these coolers ensure non-critical operating temperatures at all times – even under the extreme stress of the racetrack.
Like all AMG high-performance engines, the AMG 6.3-litre V8 is built in the AMG engine shop on the traditional "one man, one engine" principle. This means that one technician is responsible for hand-assembling a complete V8 engine to the highest quality standards – which is attested to by his signature on the AMG engine plate.
This high-performance eight-cylinder engine has the perfect partner in the form of the AMG SPEEDSHIFT PLUS 7G-TRONIC transmission. Equipped with AMG steering wheel shift paddles and three driving modes, the seven-speed automatic transmission allows a decidedly sporty or more comfort-oriented style of driving according to the driver’s preference. The different modes - "S" (Sport), " C" (Comfort) and "M" (Manual) differ in their shift characteristics and speed: gearshifts in "S" mode are around 30 percent faster than in "C", and no less than around 50 percent faster in "M" mode.
The C 63 AMG is appropriately fitted with new, 18-inch AMG light-alloy wheels in a five-spoke design. Painted in titanium grey, these high-sheen wheels in size 8.0 x 18 and 8.5 x 18 are shod with wide-base tires in size 235/40 R 18 (front) and 255/35 R 18 (rear). Even more dynamic handling is made possible by the optionally available 19-inch AMG light-alloy wheels in a multi-spoke design. The front wheels are in size 8.0 x 19 with 235/35 tires, with 9.0 x 19 wheels and 255/30 R 19 tires at the rear.
Generously dimensioned AMG high-performance braking system
Internally ventilated and perforated disc brakes all-round reside behind the spokes of the AMG wheels. The front brakes have size 360 x 36-millimetre discs with six-piston fixed callipers, while deceleration at the rear is by 330 x 26-millimetre discs with four-piston fixed callipers. The AMG high-performance braking system is characterised by great sensitivity and high fade-resistance.
It is not only in technological but also in visual terms that the new C 63 AMG is more distinctively different from the standard C-Class than ever before. The front end is dominated by the new bonnet with its two pronounced power domes, as well as the trademark AMG radiator grille with a central star and two louvres with chrome inserts. The honeycomb pattern of the grille is also reflected in the large air dams of the new, athletically contoured front apron which forms part of the AMG-specific bodystyling. The fog lamps with chrome surrounds are spaced well apart, acting together with the flared front wheel arches to accentuate the width of the car – with the striking transition from the front apron to the wings leaving a particularly strong impression. The side air vents in the front apron serve to expel the hot air from the oil coolers. If the C 63 AMG is specified with the optional bi-xenon headlamps or the Intelligent Light System, the headlamps are also dark-tinted.
Eye-catching features when viewed from the side include the 18-inch AMG light-alloy wheels, the harmoniously integrated "6.3 AMG" lettering on the front wing and the AMG side skirts. At the rear the standard LED rear lights, the AMG rear apron with its black diffuser insert and three pronounced diffuser fins, as well as the AMG sports exhaust system with two chrome twin tailpipes, provide further visual highlights that are hallmarks of the brand. The AMG spoiler lip on the boot lid reduces lift and ensures greater handling stability at high speeds.
