The new Mercedes-AMG C 63 Cabriolet combines an intensive open-air ambience with the AMG 4.0-litre V8 engine to create an exhilarating performance experience. The biturbo engine developed in Affalterbach is available in two output ratings with 350 kW or 375 kW 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 adjustable damping, as well as the rear-axle limited-slip differential.
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 number of versions as Sedan, 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 Florian Seidler, Co-CEO Mercedes-Benz South Africa and Executive Director, Mercedes-Benz Cars.
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.
Unique offering in the segment with V8 biturbo engine
In its competitive field the new C 63 Cabriolet is exceptional in every respect, being the only vehicle in the segment to boast an 8-cylinder biturbo engine. Mercedes-AMG thus meets the wishes of those customers who desire a combination of a highly emotive, unmistakable engine sound and torquey power delivery. The driver also benefits from the unrivalled performance: the C 63 S Cabriolet accelerates from 0 to 100 km/h in 4.1 seconds, the C 63 Cabriolet in 4.2 seconds. The top speed is 250 km/h (electronically limited; 280 km/h with AMG Driver’s package)
* DIN ready-to-drive condition (fuel tank 90% full) / EC ready-to-drive condition (fuel tank 90% full, with driver (68 kg) and luggage (7 kg)); ** electronically limited; with AMG Driver’s package 280 km/h
Drive system: 4.0-litre V8 biturbo engine and SPEEDSHIFT MCT 7-speed sports transmission
V8 biturbo engine with hot inside V
The 4.0-litre eight-cylinder biturbocharged engine is already used in the C 63 Sedan, 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 main advantages of this design are the compact engine construction, optimal response and low exhaust gas emissions. The ‘hot inside V’ also optimises the supply of fresh air to both exhaust gas turbochargers. Electronically controlled blow-off valves ensure a very immediate and direct response. The maximum charge pressure in the C 63 S Cabriolet is 1.2 bar, and in the C 63 Cabriolet 1.1 bar. The turbochargers reach a maximum rotational speed of 186,000 r/min.
The cylinder heads in the AMG 4.0-litre, V8 biturbo engine are made of a zirconium alloy for maximum temperature resistance and thermal conductivity. Four overhead camshafts control a total of 32 valves. Camshaft adjustment on the inlet and outlet side enables an excellent response and optimises the gas cycle for each operating point. Optimised valve springs and the low-friction valve gear with cam followers deliver further fuel savings.
In addition, forged aluminium pistons featuring a lightweight design and high strength are used. A low-friction piston ring package reduces fuel and oil consumption.
C 63 S with dynamic engine mounts as standard
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.
“One Man – One Engine”: a tradition of hand-built excellence
The biturbo eight-cylinder engine of the C 63 Cabriolet is fitted by hand in the hand-finishing section of AMG’s production plant in Affalterbach based on the “One Man – One Engine” philosophy. This means that each engine is assembled by a highly qualified technician who applies the strictest quality standards. This technician is responsible for everything from installing the crankshaft in the engine block and assembling the camshafts to wiring the engine and filling it with engine oil – as clearly evidenced by the signature on the AMG engine badge.
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 pronounced 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. Furthermore, the aluminium shift paddles are now able to transmit the driver’s commands to change gears even faster. The tangible driving dynamics are thus enhanced further.
AMG DYNAMIC SELECT transmission modes
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 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” ensures a further reduction in fuel consumption: 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.
“Sport” transmission mode is characterized by agile response to accelerator pedal input, shortened shift times and earlier downshifts. Gear changes are made significantly more emotionally appealing thanks to a double-declutching function when downshifting. On top of this, the steering and suspension feature more dynamic tuning. The experience becomes even more dynamic in “Sport Plus” mode. Numerous parameters are sharpened further here, from the highly agile throttle response and the acoustically more powerful double-declutching function, through to targeted torque control during upshifts with cylinder deactivation. The higher idle speed enables lightning-fast moving off. Suspension and steering are equally tuned for an even faster response. In addition, the exhaust system sound is more emotional.
The C 63 S has an additional “RACE” transmission mode. It is the optimal setting for tackling some ambitious laps on a closed-off race track. Here the drivetrain reacts extremely spontaneously and the ESP® switches to Sport Handling mode. In “Individual” transmission mode the driver can individually adjust the response of the drive system, suspension, transmission, exhaust system and ESP®.
The Mercedes-AMG C 63 S and the C 63 Cabriolet come standard with the class-leading six-years/100 000 km PremiumDrive maintenance plan.
