The new C 63 AMG coupé – emotion and high performance at its most attractive
Mercedes-Benz presents the new C 63 AMG Coupé, a stand-alone, high-performance car that appeals to all the senses: unmistakable design is teamed up with a high-performance drive system and dynamic handling. The new Coupé rounds off the successful C-Class AMG model range, which includes the classic Saloon as well as the practical Estate models. The C 63 AMG Coupé also enhances the AMG family of Coupés: in addition to the CLS 63 AMG and the CL 63 AMG, Mercedes-AMG GmbH is now able to offer another dream car featuring a high-performance eight-cylinder engine. The market launch commences in July 2011. Looking particularly attractive is the “Edition 1” of the C 63 AMG Coupé, available from launch and featuring exclusive equipment.
The AMG 6.3-litre V8 engine in the C 63 AMG Coupé has a maximum output of 336 kW (457 hp)and peak torque of 600 Nm (443 lb-ft), delivering powerful traction and first-class performance figures: the Coupé accelerates from 0 to 100 km/h (62 mph) in 4.4 seconds and the top speed is 250 km/h (155 mph) (electronically limited). With this kind of specification, the new two-door vehicle is set to take the lead in its segment.
The new Coupé variant benefits from all the technology updates that have served the C 63 AMG Saloon and Estate models so well. Fuel consumption is reduced through the AMG SPEEDSHIFT MCT 7-speed sports transmission with its “Controlled Efficiency” mode as standard and a new power steering pump: overall NEDC (New European Driving Cycle) consumption figures for the C 63 AMG Coupé are 12.0 l/100 km (19.60 mpg/US, 8.33 km/l).
AMG Performance package for a maximum output of 358 kW (487 hp)
This fuel consumption figure also applies to the performance version generating 358 kW (487 hp), courtesy of the AMG Performance package. Available as an option, this package improves acceleration from 0 to 100 km/h (62 mph) to 4.3 seconds, with technology transferred from the SLS AMG responsible for the 22 kW (30 hp) increase in output. The forged pistons, connecting rods and lightweight crankshaft adopted from the gull-wing model’s high-tech drive system save three kilograms in weight. This reduces inertia and enhances the agility and responsiveness of the high-revving, eight-cylinder naturally-aspirated engine. Visually, the AMG Performance package can be identified by the variable intake manifold 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 and the AMG Performance steering wheel in nappa leather with an Alcantara® grip area.
The AMG SPEEDSHIFT MCT 7-speed sports transmission provides direct and dynamic power delivery. Rather than using a torque converter, it has a compact, wet start-off clutch which reduces the losses associated with conventional automatic transmission and thereby significantly lowers fuel consumption. The Controlled Efficiency “C” mode also plays a significant part in this. By providing earlier and more comfortable upshifts while maintaining the lowest possible engine speed and “soft” accelerator characteristics, the AMG SPEEDSHIFT MCT 7-speed sports transmission helps the driver achieve better fuel economy figures. At the same time, the power transmission, which is exclusive to Mercedes-AMG, excites with its high level of variability and scintillating dynamism: the “S,” “S+” and “M” transmission modes make the vehicle even more responsive and can be selected using the new rotary transmission switch familiar to many from the SLS AMG. Shorter gear shift intervals and higher engine revs assure the ultimate in emotional appeal. The double-declutching function is also activated in the “S,” “S+” and “M” modes, thereby further increasing driving enjoyment. The gear shifts take just 100 milliseconds in “S+” and “M” transmission modes. Using the RACE START function the driver can explore the vehicle’s full acceleration capability.
Specific AMG sports suspension for great dynamism and ride comfort
It is not just the engine and power transmission which characterise the C 63 AMG Coupé’s dynamic quality – the AMG sports suspension and AMG high-performance braking system are also key here. In contrast to the series production suspension system, the top-of-the-range AMG model has a specially designed three-link front suspension, reinforced multi-link independent rear suspension and a wider track all round. The stiffer elastokinematics, the autonomous axle kinematics with more negative all-round camber and stabilisers with a larger cross-section all give greater responsiveness and greater lateral acceleration. Selective damping with specially modified spring and damper rates optimises both the response characteristics of the springs as well as the ride comfort.
The AMG sports speed-sensitive power steering with direct steering ratio (13.5 : 1) gives excellent road surface contact and makes a significant contribution to the vehicle’s direct, responsive handling. This is complemented perfectly by 3-stage ESPÒ: the Electronic Stability Program gives three individual control strategies at the touch of a button: the ESPÒ button in the centre console allows the driver to choose between “ESP ON,” “ESP SPORT HANDLING MODE” and “ESP OFF.” The AMG high-performance brake system has internally ventilated and perforated brake discs on all wheels: it is characterised by outstanding responsiveness, short stopping distances and excellent fatigue strength.
Confident and athletic: the design of the C 63 AMG coupé
The Coupé version of the C 63 AMG is compelling in visual terms as well, with an assured, athletic presence that is reminiscent of the high-performance SL 63 AMG Roadster. All AMG-specific design features have been skilfully combined with classic coupé proportions. This compact two-door Coupé excites with its low profile, powerful-looking shoulder line and slimline C-pillar. The short overhang, long engine cover, steeply sloping windscreen and long, stretched-out roof are also striking elements of its overall style.
The distinctive, strikingly arrow-shaped front section is characterised by features typical of AMG: a new AMG front apron including lower cross-struts finished in high-gloss black, LED daytime driving lamps specifically created for AMG and side air outlets. The large Mercedes star is positioned on a wing-shaped horizontal grille slat in the new radiator grille and, together with the newly-designed aluminium engine cover which has power domes, underlines the masculine feel of the vehicle. The new clear glass headlamps, in particular in combination with the Intelligent Light System (ILS) as an optional extra, are further eye-catching features.
When viewed from the side, the wide front wing bearing the “6.3 AMG” legend, the AMG side sill panels and the new, high-sheen AMG 5-twin-spoke light alloy wheels in titanium grey finish all stand out. Good contact with the road is provided by the wide 235/40 R 18 (front) and 255/35 R 18 (rear) tyres. Attention is drawn at the rear to the distinctive AMG rear apron with a striking black diffuser and three diffuser fins as well as the two chrome twin tailpipes of the AMG sports exhaust system.
