Affalterbach – 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 reducing fuel consumption significantly. 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 helps to reduce the combined NEDC fuel consumption by about ten percent to 12.0 l/100 km (Estate: 12.3 l/100 km). The output of the AMG 6.3-litre V8 engine is unchanged at 336 kW (457 hp) and can be increased to a maximum of 358 kW (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 AMG is 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, especially when the optional Intelligent Light System (ILS) is also specified. 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.1 February 2011
The rear view of the C 63 AMG also 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.
AMG SPEEDSHIFT MCT 7-speed
Under the skin, too, the top C-Class model boasts a wealth of new technology including the AMG SPEEDSHIFT MCT 7-speed sports transmission – another advanced feature adopted from the SL 63 AMG. 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 “Controlled Efficiency” mode and a new power steering pump: at 12.0 litres per 100 km (Estate: 12.3 l/100 km) the combined NEDC fuel consumption of the C 63 AMG is 1.4 litres (Estate: 1.3 litres) lower than that of the predecessor model; this represents a reduction in fuel consumption of some ten percent. The CO2 emissions figure is now 280 (Estate: 288) grams per kilometre. Both power variants have identical fuel consumption and emission figures.
The AMG SPEEDSHIFT 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 Controlled Efficiency “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 336 kW (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 AMG retains its predecessor’s position as the top performing model in its segment: acceleration from standstill to 100 km/h takes just 4.5 seconds (Estate: 4.6 s) while the top speed is 250 km/h (electronically limited).
Even more dynamic performance is available with the optional AMG Performance package: this offers 358 kW (487 hp) and allows a 0-100 km/h 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 calipers 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.
