<< Prev Page 2 of 3 Next >>  The transmission plays a major part in the direct and sporty character of the new Mercedes-AMG C 63 Cabriolet. The AMG SPEEDSHIFT MCT 7-speed sports transmission impresses with its tailor-made dynamics and high variability. Whether automatic or initiated by the driver using the steering wheel shift paddles, upshifts and downshifts are executed quickly and immediately. This is achieved by specifically adjusting the engine and transmission parameters.The fascinating agility and high cornering speed of the C 63 Cabriolet are also thanks to the standard-fit AMG Ride Control suspension with adaptive damping adjustment. This combines a sporty with a comfortable set-up. The driver can select the three suspension settings "Comfort", "Sport" and "Sport Plus" via a button in the centre console. Whatever the setting, each wheel is individually electronically controlled automatically. A four-link front suspension with radial, racing-style brake connections is used. Model-specific steering knuckles and a wider track allow greater lateral acceleration. The rear axle was completely newly developed for the Coupé and Cabriolet. The multi-link concept ensures highly precise wheel control and increased stiffness. The AMG-specific rear axle carrier makes the wider track possible, with the contact surfaces of the wheel bearings moved out by another 25 millimetres compared with the Saloon and Estate. Other innovations include AMG-specific wheel carriers, stiffer elastokinematic tuning and higher negative camber. As standard the C 63 Cabriolet is shod with 10-spoke light-alloy wheels 9.0 J x 18 (front) and 10.5 J x 18 (rear) with rims painted titanium grey with a high-sheen finish and tyres in size 255/40 R 18 (front) and 285/35 R 18 (rear). The C 63 S Cabriolet runs on tyres of sizes 255/35 R 19 (front) and 285/30 R 19 (rear) mounted on 9.0 J x 19 (front) and 10.5 J x 19 (rear) 5-twin-spoke light-alloy wheels, also painted titanium grey with a high-sheen finish. Other tyre/wheel combinations are optionally available. These include mixed-size tyres with forged cross-spoke wheels, painted matt black with high-sheen rim flange. The front axle features tyres of size 255/35 R 19 on 9.0 J x 19 wheels. The rear axle is fitted with tyres of size 285/30 R 20 on 10.5 J x 20 wheels. For improved traction and vehicle dynamics, the C 63 Cabriolet is provided with a mechanical rear-axle limited-slip differential, while the C 63 S Cabriolet comes with an electronic version. Both differentials reduce the slip on the inside wheel when cornering, without control interventions in the braking system. The advantage: 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 moving off. The model-specific, completely redesigned rear axle was specially adapted to the higher vehicle dynamics of the Cabriolet. The greatest benefit from the electronic rear-axle limited-slip differential - which is installed as standard exclusively on the C 63 S - is the even more sensitive and faster control, which pushes the thresholds higher and makes it even easier to drive at the vehicle's limits. The 3-stage ESP with "ESP ON", "ESP Sport Handling Mode" and "ESP OFF" settings works in perfect unison with the rear-axle limited-slip differential and is optimally tuned to the outstanding dynamics. The driver is able to influence the characteristics of the C 63 with four different AMG DYNAMIC SELECT transmission modes. The driver decides on the desired driving experience, from comfortable-economical to super-sporty, using a controller to the left of the touchpad. "Comfort" is the well-balanced transmission mode with a comfort-oriented suspension and steering set-up, as well as a fuel-efficient powertrain configuration - including smooth gearshifts and a discreet engine note. The "sailing function" for a further reduction in fuel consumption is new: when the driver releases the accelerator in a speed range between 60 and 160 km/h, the clutch of the MCT transmission is disengaged and the engine is decoupled from the powertrain. The electronics reduce the engine speed to idle level, and the driving resistance is reduced by the compression and frictional forces of the engine in overrun mode. The transmission modes "Sport" and "Sport Plus" enhance the sporty intensity. The C 63 S also comes with the "RACE" mode, which provides the optimum setting for challenging laps on private racing circuits. Unique in its segment, the C 63 S Cabriolet - like the Saloon, Estate and Coupé - is equipped with dynamic engine mounts. These help to further resolve the conflicting aims of comfort and dynamic performance. These dynamic mounts are very quickly and variably able to adapt their stiffness to the driving conditions and requirements. 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. These measures enhance the vehicle's precision when driven dynamically. For example, the steering response and feedback are even more direct. The electromechanical, speed-sensitive sports steering ensures precise, agile handling. The driver benefits from the direct, linear steering ratio of 14.1:1 and an optimised response. It also features variable power assistance with the three characteristics "Comfort", "Sport" and "Sport Plus". The power steering is not only speed-sensitive but also factors in the current lateral acceleration, the selected AMG DYNAMIC SELECT transmission mode or the setting of the AMG Ride Control adaptive damping. The high-performance braking system of the C 63 Cabriolet ensures short stopping distances and excellent control with large cross-drilled and vented brake discs measuring 360 millimetres in diameter at the front and rear. The C 63 S Cabriolet is fitted with compound brake discs at the front with a diameter of 390 millimetres to account for the increased performance. A high-performance compound braking system with ceramic discs measuring 402 millimetres in diameter on the front axle is optionally available for the C 63 S Cabriolet. They weigh just half of comparable conventional brake discs and as a result reduce unsprung masses. This in turn substantially improves the steering response. << Prev Page 2 of 3 Next >> |
