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.
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 sports transmission from the SL 63 AMG
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 dynamicovertaking 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).
Performance package: technology transfer from the SLS AMG
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.

Optimised suspension, new steering system reduces fuel consumption
The AMG sports 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.
The AMG speed-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.
Interior: high quality and perceived value
Even a quick glance at the interior of the C 63 AMG reveals 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 quality look and feel meet the highest standards. 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, which is enhanced with high-gloss black piano lacquer trim elements, is the new rotary control for selecting the transmission modes C, S, S+, M and RACE START. The special AMG sports seats with integral head restraints and adaptive backrests are available from launch with combined ARTICO/DINAMICA black upholstery. DINAMICA is a new type of breathable man-made fibre which is pleasant to the touch and is characterised by low emissions and a high degree of lightfastness. The side bolsters of the AMG sports seats are covered in ARTICO while the centre panels of the seat cushions are also upholstered with DINAMICA.
Available as an option, designo leather appointments give the interior of the C 63 AMG a particularly exclusive character: four single colours and three two-tone combinations are available. As a further option, these can be complemented with “extended black designo leather appointments” for the top section of the dashboard and the upper section of the door linings.
Other attractive optional appointments are also exclusively available for the C 63 AMG from the AMG Performance Studio:
- AMG five-spoke light-alloy wheels, painted in titanium grey with a high-gloss finish, with 235/40 R 18 (front) and 255/35 R 18 (rear) tyres

New generation of telematics is the first to feature internet access
The C-Class sees the debut of a new telematics generation which will also be gradually introduced in other model series. Major new features include greater operating convenience, larger displays, telephone directory transfer via Bluetooth®, wireless music reproduction and a USB interface in the centre console.
The top-of-the-range COMAND Online system now provides internet access for the first time. When the car is stationary the customer can browse freely or surf to a Mercedes-Benz Online service whose pages load particularly rapidly. The integrated services include weather information and a local search function as well as the option of downloading a route that has been previously configured on a PC using Google maps and sent to the car. The navigation system of COMAND Online also has added functions. New features include a 3D display with virtual city views. Also new: routes covered can be recorded and repeated later, specific personal destinations can be entered and stored and three alternative routes can be displayed on the screen – one of them a particularly economical variant.
As a first in the C-Class, the Becker®MAP PILOT makes a low-cost navigation function, which can also be retrofitted, available for the entry-level Audio 20 radio. Its advantages over aftermarket solutions include integrated operation via the COMAND Controller and the Audio 20 display.
