The Mercedes-AMG C 63 S Coupé fascinates even at first glance with its impressive proportions. The expressive exterior design differs significantly from the standard Mercedes-Benz model, which shares merely the same doors, roof and boot lid. The powerful eight-cylinder engine as well as the wider track of the front and rear axles call for a redesigned front end, a model-specific rear assembly and new side walls. The flared wheel arches make the AMG Coupé 64 millimetres wider at the front and 66 millimetres wider at the rear, enabling the vehicle to hug the road better.
The larger wheel arches allow the use of wider tyres (up to 255 millimetres on the front axle and up to 285 millimetres on the rear axle), contributing to improved lateral acceleration, traction and agility. Under the outer skin, the body structure has been reinforced in key areas to transfer and compensate the extreme longitudinal and lateral forces from the powertrain and suspension. There is also the model-specific rear axle carrier.
The 60-millimetre-longer aluminium bonnet is adorned by two distinctive power domes, which are among the typical distinguishing features and underscore the muscular appearance. The extremely wide front section is characterised by large air inlets and precisely positioned flics. The low, arrow-shaped “twin blade” radiator grille with AMG lettering visually lowers the vehicle’s centre of gravity. The typical AMG “A-wing” is serving as an air deflector for the three cooling air intakes. Additional flics ensure an optimal flow of air to the cooling modules. And a front splitter at the bottom of the front apron helps to reduce front-axle lift.
The side line, too, presents an entirely unique face thanks to the large wheels, which finish flush with the body on the far outside, and the special side skirts. The lateral inward step from door to sill lends additional emphasis to the wide base. Added benefit of the newly designed body elements: no compromises were required with regard to the connection of the aprons and other components: every joint and light-catching contour blends in harmoniously with the overall design. In the diagonal view from behind, the muscular line from roof to shoulder via side wall and wheel cut-out looks especially impressive, adding to the impression of an intricately modelled sculpture with alternating light reflections. Refined detail: In typical sports car fashion, the exterior mirrors are mounted on the door rather than in the mirror triangle.
Taking its inspiration from the S-Class Coupé, the completely redesigned rear end includes a diffuser insert that invokes a typical feature from motor sport. The special design of the laterally positioned, optical air outlet openings improves the rear air flow, allowing it to break away with aerodynamically advantageous precision. Features such as the narrow rear reflectors reinforce the impression of width. The boot lid includes a narrow spoiler lip in the form of a sharp blade. It not only looks elegant, but also produces more downforce on the rear axle.
Interior with high-class appeal
The careful selection of high-class materials, their high-quality touch and feel as well as the meticulous workmanship lend the interior a high-class appeal. The instrument panel is trimmed with black ARTICO man-made leather. Numerous AMG-specific controls underscore the motor sport heritage. AMG Performance seats are available as standard, allowing the occupants a lower seating position and are more strongly contoured for increased lateral support.
Also as regards its engine, the C 63 S Coupé occupies an exceptional status among the competition, being the only vehicle in the segment to boast an 8-cylinder biturbo engine. Mercedes-AMG thus precisely meets the wishes of those customers who desire a combination of a highly emotionally appealing, unmistakable engine sound and high-torque power delivery.
The driver also benefits from the impressive performance: the C 63 S Coupé accelerates from 0 to 100 km/h in just 3.9 seconds. The top speed is 290 km/h (with AMG Driver’s Package). With a power-to-weight ratio of 3.4 kg/hp (C 63 S), the new AMG V8 top model is the head the field in this segment.
New V8 biturbo closely related to the engine in the Mercedes-AMG GT
The 4.0-litre eight-cylinder biturbo engine is already used in the C 63 S Sedan. 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 a ‘hot inside V’. The main advantages of this design are the compact engine construction; optimal response and low exhaust gas emissions.
A host of measures combines maximum performance with favourable fuel consumption figures. 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.
Variable dynamics: 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 S Coupé. 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 noticeably faster than in the previous model. Especially in “Sport+” and in manual mode, the transmission response is now even more prompt. This enhanced spontaneity was made possible by optimising the transmission hardware and software. Furthermore, the aluminium paddle shifters are now able to transmit the driver’s commands to change gears even faster than before. The tangible driving dynamics are thus enhanced further.
AMG DYNAMIC SELECT driving modes
The four different driving modes “Comfort“, “Sport“, “Sport+“ and “Individual“ allow drivers to influence the characteristics of their Coupé. The C 63 S Coupé has an additional “RACE” driving mode allowing for a completely personalised driving style. The driver selects the driving experience using a controller to the left of the touchpad.
“Comfort” is the well-balanced driving mode with a comfort-oriented suspension and steering set-up as well as a fuel-efficient powertrain configuration – including smooth gearshifts and a discreet exhaust note. The “sailing function” for a further reduction in fuel consumption is completely 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 driving modes “Sport“ and “Sport+“ enhance the sporty intensity. “RACE“ is exclusive to the C 63 S Coupé and the optimal setting for ambitious laps on a racetrack.
C 63 S Coupé with dynamic engine mounts as standard
Unique in its segment, the C 63 S Coupé is equipped 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 a more precise driving sensation.
Safety of the highest calibre
All assistance systems available for the C-Class Coupé can also be ordered for the C 63 S Coupé. It comes as standard with the further advanced ATTENTION ASSIST drowsiness detection system and Driver Assistance Package Plus, a combination of complementary safety and assistance systems helps to relieve driver strain, reduces the risk of accidents and improves protection for the occupants as well as other road users.
