Mercedes-Benz C63 AMG Coupe
Mercedes-Benz presents the new C63 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 AMG 6.3-litre V8 engine in the C63 AMG Coupé has a maximum output of 336 kW (451 hp) and peak torque of 600 Nm, delivering powerful traction and first-class performance figures: the Coupé accelerates from 0 to 100 km/h in 4.4 seconds and the top speed is 250 km/h (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 C63 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 consumption figures for the C63 AMG Coupé are 12.0 l/100 km.
This fuel consumption figure also applies to the performance version generating 358 kW (480 hp), courtesy of the AMG Performance package. Available as an option, this package improves acceleration from 0 to 100 km/h 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.
It is not just the engine and power transmission which characterise the C63 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 Coupé version of the C63 AMG is compelling in visual terms as well, with an assured, athletic presence that is reminiscent of the high-performance SL63 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 powerdomes, 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.
