<< Prev Page 2 of 2  The C 63 now makes use for the first time of the AMG SPEEDSHIFT MCT 9G transmission, which the Mercedes-AMG developers have tuned specifically for a dynamic driving experience. A wet start-off clutch continues to replace the torque converter. This saves weight and optimises the response to the driver's accelerator pedal input, particularly during acceleration and load changes.The multiple downshift function allows more spontaneous bursts of speed, while the double-declutching function in "Sport" and "Sport+" drive programmes makes for an even more emotional driving experience. Defined ignition adjustments also provide faster gear shifts in the other modes. In all modes moving off occurs in first gear in order to always guarantee a dynamic driving experience. "Manual" mode can be selected using a separate button in the centre console. The gear changes are based on the selected drive programme, and the driver can now change gear using the paddles on the steering wheel. Moreover, the transmission stays in the selected gear and does not automatically shift up when the engine speed reaches the limit. Depending on the engine, up to six drive programmes are available: "Slippery", "Comfort", "Sport", "Sport+", "RACE" and "Individual". These levels are selectable via the gearshift paddle in the centre console and stored with the new drive programme attribute AMG DYNAMICS, which can be adjusted to match the C 63's handling characteristics to different demands and driving conditions in a much more differentiated way. Behind the umbrella term AMG DYNAMICS are the agility functions "Basic", "Advanced", "Pro" and "Master", which are automatically selected by the respective drive programme. Parameters relevant to driving, such as the response of the engine and suspension or the control thresholds of the completely redeveloped ESP, are intelligently adapted according to the drive programme. The spectrum ranges from extremely safety-oriented to highly dynamic. The "Master" mode, which is included in the RACE drive programme, guarantees optimal agility and makes ideal use of the new C 63's high driving dynamics potential - for example by means of higher yaw rates and faster response of accelerator, gearshift and electronically controlled rear-axle limited-slip differential. Irrespective of the drive programmes, as before the driver can use the display buttons in the centre console to directly select manual transmission mode, their favoured suspension level and also the exhaust system, for instance. As the virtual race engineer for recording data when driving on closed-off race tracks, AMG TRACK PACE provides a significantly extended and even more precise scope of functions. On the C 63 S, AMG TRACK PACE is a standard (C 63: optional) part of the optional COMAND Online infotainment system. If this function is enabled, while driving on a race track, over 80 vehicle-specific sets of data (e.g. speed, acceleration) are recorded ten times per second. On top of this there are displays of lap and sector times and also the respective difference for a reference time. Because specific display elements are shown in green or red, the driver is able to see at a glance without reading numbers whether he/she is currently faster or slower than the best time. After putting in some fast laps, the driver can use the data to analyse and, if necessary, improve his or her driving skills. In addition, acceleration and deceleration values (e.g. 0-100 km/h, ½ mile, 100-0 km/h) can be measured and saved. Thanks to a new developed algorithm which determines the vehicle position as precisely as possible, AMG TRACK PACE even detects when the circuit is left or shortened. Alongside GPS data, the sensors available in the vehicle (acceleration, gyroscope, steering angle, wheel speeds) are used. The data are displayed on the multimedia display, in the instrument cluster and on the head-up display. Known race tracks, for example the Nürburgring or Spa Francorchamps, are already stored. Furthermore, it is also possible to record your own circuits. The map display can be switched from 2D to 3D and updated online. With its adjustable, electronically controlled damping system, the AMG RIDE CONTROL steel suspension of the C 63 provides both sporty driving dynamics and brand-typical comfort on long journeys. The basis for this is formed by the 4-link front axle and multi-link independent rear suspension. The AMG-specific kinematics and elastokinematics with newly developed components result in very high camber stability when cornering at speed. The axial brake connection on the front axle supports the agile and precise handling. The adaptive damping adjustment comes as standard. This fully automatic, electronically controlled system adjusts the damping at each wheel to the current requirements. This improves driving safety and ride comfort. The damping is adjusted individually for each wheel, and depends on the driving style, the road surface and the selected suspension setting. The ideal operating point can be selected at all times on the basis of a broad scope of information relating to acceleration or vehicle speed, for example. Via a switch on the centre console the driver can select between three different sets of damper characteristics, namely "Comfort", "Sport" and "Sport+", and thus individually influence the driving experience - from highly comfortable to sportily taut. For improved traction and driving dynamics, the C 63 and C 63 S are equipped with an electronically controlled rear-axle limited-slip differential. This reduces the slip on the inside wheel when cornering, without any control intervention in the braking system. The result is that it allows the driver to accelerate out of corners earlier thanks to the improved traction. The car remains more stable when braking from high speeds, and the limited-slip differential also improves traction when accelerating fast from a standing start. The greatest benefit of the electronically controlled rear-axle limited-slip differential is the especially sensitive and fast control, which pushes the critical threshold higher, making it even easier to drive at the vehicle's limits. The electromechanical speed-sensitive power steering has a variable ratio. It impresses with its precise, authentic feedback. The steering servo assistance is reduced at high speeds, and continuously increases at lower speeds. This means that comparatively little steering force is required at low speeds, and that the best possible control over the vehicle is maintained at high speeds. The steering servo assistance in the two modes "Comfort" and "Sport" is automatically linked with the currently selected drive programme. All four body styles are available as basic model and S-model: the proven AMG 4.0-litre V8 biturbo engine in this case puts out 350 kW (476 hp) or 375 kW (510 hp), while the maximum torque is 650 or 700 Nm. Depending on body style, the C 63 S accelerates from zero to 100 km/h in 3.9 seconds, the C 63 in 4.0 seconds. The top speed is up to 290 km/h for the C 63 S and 250 km/h for the C 63 (both electronically limited). The 4.0-litre eight-cylinder biturbo engine is already used in numerous AMG Performance vehicles. A characteristic feature is that the two turbochargers are positioned not on the outside of the cylinder banks, but inside the cylinder "V". The main advantages of this design are the compact engine construction and optimal response. The spray-guided direct petrol injection system ensures clean and efficient combustion with high thermodynamic efficiency. Fast-acting piezo injectors enable multiple injections of fuel to be delivered to the engine on demand and with the utmost precision. The large cooling system guarantees the performance of the engine even under extreme loading - such as at track days on the race track. The same is true for the flow-optimised cylinder heads, which are made of a special heat-resistant alloy. Continuous adjustment of the intake and exhaust camshafts improves power delivery and efficiency. It delivers excellent throttle response and optimises the charge cycle for every operating point. An oil pump with variable control also contributes to low fuel consumption. One mechanic assembles each engine in the engine shop in Affalterbach according to the "one man - one engine" principle. The typical V8 engine sound is another key element of the AMG driving experience. The C 63 comes as standard with an AMG exhaust system with a variable flap. This is steplessly map-controlled depending on the drive programme, the power demanded by the driver and the engine speed. The engine sound varies accordingly between discreet/suitable for long-distance driving, and robust/emotively appealing. A Performance exhaust system with three selectable exhaust flaps is optionally available for both engine variants. This gives the driver an even wider sound range. In any case, the exhaust systems are designed in such a way that all statutory noise limits are complied with at all times, irrespective of the flap position. The more powerful C 63 S comes with dynamic engine mounts. These resolve the conflicting aims of comfort and dynamic performance by reducing vibrations in the engine/transmission unit. These dynamic mounts are instantly and variably able to adapt their rigidity to the driving conditions and style of driving. Soft engine mounts improve comfort, as they provide more effective decoupling of noise and vibration. However, handling and agility benefit from a generally stiffer mount set-up. The driver feels more connected to the vehicle when driving dynamically, as there is more feedback and the steering response is more direct. All in all the driver benefits from more precise vehicle control: minimised mass movements of the major assemblies mean less corrective action to be taken by the driver when steering into bends. The optional ENERGIZING comfort control is also available for the new C 63. It networks together the various comfort systems in the vehicle and uses specific functions of the air conditioning and seats (heating, ventilation) plus lighting and music moods. Depending on the mood or requirement of the driver, it generates a special wellness set-up to enhance well-being and performance. << Prev Page 2 of 2 |
