Mercedes-AMG C 63 Cabriolet

Open-air performance for the C-ClassMercedes-AMG C 63 S Cabriolet (A 205), 2016

The new C 63 Cabriolet combines an intensive open-air ambience with the AMG V8 engine to create an exhilarating performance experience. The biturbo engine developed in Affalterbach is available in two output ratings with 350 kW (476 hp) or 375 kW (510 hp) and provides performance on a par with a sports car. Flared wheel arches at the front and rear, the wide track and the large wheels underscore the powerful looks. The agile longitudinal and lateral dynamics come courtesy of the sophisticated AMG RIDE CONTROL suspension with adaptive damping adjustment, the rear-axle limited-slip differential and the dynamic engine mounts.

Performance-oriented automotive enthusiasts can enjoy the largest selection in the market segment with the Mercedes-AMG C-Class: it is now available in a total of twelve versions as Saloon, Estate, Coupé and Cabriolet; with a choice of V6 biturbo engine and all-wheel drive or V8 biturbo engine in two output ratings, rear-wheel drive and rear-axle limited-slip differential. “The C-Class is a decisive factor in our company’s success. The new combination of intensive open-air ambience and powerful V8 engine is unique in the segment and perfectly supplements our large C-Class range,” says Tobias Moers, CEO of Mercedes-AMG GmbH. Extensive know-how from motorsport and the passion of the AMG engineers, designers and product managers form the basis for the emotive driving experience with the new Performance Cabriolet.

The 4.0-litre eight-cylinder biturbo engine is already used in the C 63 Saloon, Estate and Coupé. It is also installed in the GT sports car with dry sump lubrication. A characteristic feature is that the two turbochargers are positioned not on the outside of the cylinder banks, but between them in the “V” – experts call this the “hot inside V.”

The typical V8 engine sound was likewise a key development goal. The Coupé adopted the composition with its sonorous bass tones, powerful mid tones and increasing trebles as the engine speed increases. A model-specific exhaust system with flap technology is used as standard. It is automatically map-controlled depending on the AMG DYNAMIC SELECT transmission mode, the power demanded by the driver and the engine speed. Optionally available is the Performance exhaust system, which allows the sound to be modulated at the press of a button. In any case, the exhaust systems are so designed that all noise limits are complied with irrespective of the flap position.

Faster gearshifts: the AMG SPEEDSHIFT MCT 7-speed sports transmission

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.

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 mm 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.Mercedes-AMG C 63 S Cabriolet (A 205), 2016

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.

Rear-axle limited-slip differential: optimal traction, including on the race trackMercedes-AMG C 63 S Cabriolet (A 205), 2016

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.

“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.Mercedes-AMG C 63 S Cabriolet (A 205), 2016

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.

C 63 S with dynamic engine mounts as standardMercedes-AMG C 63 S Cabriolet (A 205), 2016

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.

AMG high-performance braking system with front tyres of size 255/35 R 19 on 9.0 J x 19 wheels

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 mm 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 mm to account for the increased performance. A high-performance compound braking system with ceramic discs measuring 402 mm 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.
