Affalterbach. New engine, new transmission, new all-wheel drive, new exterior and interior design: On the S 63 4MATIC+ (fuel consumption combined: 8.9 l/100 km; CO2 emissions combined: 203 g/km), Mercedes-AMG has dramatically honed the driving dynamics and looks further. For improved performance with significantly reduced fuel consumption, the AMG 4.0-litre V-8 Biturbo engine with cylinder deactivation replaces the previous 5.5-litre V-8 Biturbo. Despite the smaller displacement, the new engine puts out 450 kW (612 hp) and thus exactly 20 kW (27 hp) more than the preceding model. With a sprint time of 3.5 seconds from zero to 100 km/h, the performance luxury saloon is on par with full-blooded sports cars. The AMG SPEEDSHIFT MCT 9‑speed sports transmission replaces the previous 7-speed gearbox. This has enabled more agile response times to be achieved. The fully variable AMG Performance 4MATIC+ all-wheel-drive system provides optimal traction.

At the same time as the S 63 4MATIC+, the top-of-the-range model S 65 (fuel consumption combined: 11.9 l/100 km; CO2 emissions combined: 279 g/km) receives a visual update that underscores the superiority of the high-end 12-cylinder model. Its 6.0-litre V-12 Biturbo engine retains its output of 463 kW (630 hp) and peak torque of 1000 Newton metres. Thanks to the highest stage of development of the V-8 and V-12 biturbo engine, both new models deliver more output and torque than the competitors.

New MULTIBEAM LED headlamps and the updated front apron with jet wing underscore the more expressive appearance of both S-Class models. At the rear, the new apron and modified tailpipe trim add distinctive design focuses.

"Impressive power, torque and performance on the road, as well as the expressive design distinguish the new Mercedes-AMG S 63 4MATIC+ and the new S 65. With the S 63, we additionally took a major development step that supports our leadership claim in the areas of driving dynamics, performance, traction, equipment and demonstrative comfort. The S 65 with its high-torque 6.0-litre V-12 Biturbo engine remains the spearhead of the S-Class models“, says Tobias Moers, Chairman of the Managing Board of Mercedes-AMG GmbH.

4.0-litre V-8 biturbo engine with twin-scroll turbochargers

The AMG 4.0-litre V-8 Biturbo engine in the S 63 4MATIC+ comes exclusively in the highest performance stage to date rated at 450 kW (612 hp). The peak torque of 900 Nm also represents a new maximum. It is available across a wide rev range between 2750 and 4500 rpm, and thereby provides a sense of superior poise. The sprint from standstill to 100 km/h takes just 3.5 seconds, faster than in any other performance luxury saloon, and the dynamic push in the back does not end before reaching the electronically limited top speed of 250 km/h (with AMG Driver's Package: 300 km/h).

The further advanced AMG 4.0-litre V-8 Biturbo engine utilises well-proven twin-turbo forced induction, with the two chargers not located outside on the cylinder banks, but rather between them in the V of the cylinders. The advantages of the "hot inner V" are a compact engine design, an immediate response from the turbochargers and low exhaust emissions thanks to optimum airflow to the close-coupled catalytic converters.

Two twin-scroll turbochargers provide even better fresh-mixture cylinder charge. The results are a higher output, more torque already at low engine speeds, and a very spontaneous throttle response.

'AMG Cylinder Management' cylinder deactivation system

For maximum efficiency, Mercedes-AMG equipped the V-8 engine in the S 63 4MATIC+ with the AMG Cylinder Management cylinder deactivation system. In the partial-load range, cylinders two, three, five and eight are deactivated, which significantly lowers the fuel consumption. With a combined fuel consumption of 8.9 litres and combined CO2 emissions of 203 grams per kilometre, the new S 63 4MATIC+ is among the leaders in its competitive segment.

When the driver has selected the "Comfort" transmission driving mode, the cylinder deactivation system is available in the wide engine speed range from 1000 to 3250 rpm. The AMG main menu on the instrument cluster informs the driver whether the cylinder deactivation system is in use and whether the engine is presently operating in the partial or full-load range. The transition from four to eight-cylinder operation is immediate, fast and imperceptible, so that the passengers do not experience any loss of comfort whatsoever.

Short shift times, high efficiency: the AMG SPEEDSHIFT MCT 9-speed sports transmission

For the first time, the S 63 is fitted with the AMG SPEEDSHIFT MCT 9-speed sports transmission, which impresses with extremely short shift times, fast multiple downshifts and a rev-matching function. A wet start-off clutch replaces the torque converter of the production model. This saves weight and improves the response to the driver's accelerator pedal input, particularly during acceleration and load changes.

The extremely high torque of the S 65 is transferred by the proven AMG SPEEDSHIFT 7G-TRONIC PLUS transmission. It delivers convincing tailor-made dynamics and high variability. Whether automatic or initiated by the driver using the steering wheel paddle shifters, upshifts or downshifts are affected quickly and instantly. Especially in the "Sport+“ and in manual driving modes, the transmission is very fast and responsive.

AMG Performance 4MATIC+ variable all-wheel drive

The LHD version of the S 63 4MATIC+ comes as standard with the fully variable AMG Performance 4MATIC+ all-wheel-drive system. This intelligent system combines the advantages of different drive concepts: The fully variable torque split between front and rear axle, another first, ensures not optimal traction. What is more: The driver is also able to rely on high handling stability and a high level of safety under all conditions, in the dry, in the wet or in snow. The transition from rear-wheel to all-wheel drive and vice versa is seamless, because the intelligent control is integrated into the overall vehicle system architecture.

An electro-mechanically controlled clutch connects the permanently driven rear axle variably to the front axle. The best possible torque split is continuously computed according to the driving conditions and driver's input. The performance saloon can thus be driven in a continuously variable way from traction-oriented all-wheel drive to purely rear-wheel drive. Transitions are seamless and based on a sophisticated matrix. Alongside traction and lateral dynamics, the all-wheel drive also improves the longitudinal dynamics for even more powerful acceleration.

The RHD version of the S 63 is equipped with the new engine and the new transmission. It is available solely with rear-wheel drive. The same applies to the S 65.

For a personalised experience: AMG DYNAMIC SELECT driving modes

The four AMG DYNAMIC SELECT driving modes, "Comfort“, "Sport“, "Sport+“ and "Individual“, allow the driver to influence the characteristics of the S 63 4MATIC+ and the S 65 extensively. Each driving mode modifies key parameters such as the response of engine, transmission, suspension, steering, ESP®, and all-wheel drive (in the S 63 4MATIC+). Independently of the DYNAMIC SELECT driving modes, the driver has the option of pressing the "M" button to switch directly to manual mode, in which gearshifts are executed exclusively using the paddle shifters on the steering wheel. If required, the suspension settings can be specially selected as well. The 3-stage ESP® and the exhaust flap can also be switched with a special AMG button.

"Comfort" is the well-balanced driving mode with a comfort-oriented suspension and steering set-up, as well as a consumption-oriented powertrain configuration and early upshifts – including smooth gear changes and a discreet engine sound. Cylinder deactivation (in the S 63 4MATIC+), ECO start/stop function and sailing function (in the S 63 4MATIC+) are active: When the driver releases the accelerator in a speed range between 60 and 160 km/h, the clutch of the MCT transmission disengages and the engine is decoupled from the powertrain. The electronics lower the engine speed to idle and driving resistance is reduced by the compression and friction forces of the engine on overrun.

The DYNAMIC SELECT driving modes "Sport“ and "Sport+“ are designed for high driving dynamics. This is provided by the agile accelerator pedal characteristics with direct set-up and the emotionally appealing gearshifts with shortened shift times and rev-matching function on downshifts. The increased idle speed in "Sport+“ furthermore makes particularly fast start-offs and even better acceleration from standstill possible.

In addition, the S 65 features the "Curve“ driving mode, active in the speed range between 15 km/h and 180 km/h. A curve-tilting function is integrated into the MAGIC BODY CONTROL suspension of the S 65. As a result, the vehicle tilts to the inside of the turn by up to 2.65 degrees, similar to a motorcycle rider. This reduces the perceived lateral forces and increases the ride quality.

RACE START now even easier

The RACE START function is now also available in the S 63 4MATIC+. It now has a new and simplified operating logic: In the "Sport“ or "Sport+“ driving modes, the driver only has to press hard on the brake pedal with their left foot while fully depressing the accelerator pedal with their right foot at the same time.

The on-board electronics will then set the optimum engine speed. Depending on the requirements or the road surface conditions, the engine speed can be increased or lowered in a certain range by operating the paddle shifters. As soon as the driver releases the brake pedal, the S 63 4MATIC+ storms forward with optimal traction. The saloon then completes the sprint from zero to 100 km/h in 3.5 seconds.

Pure sound: the controllable AMG Performance exhaust system

The S 63 4MATIC+ is fitted as standard with the controllable AMG Performance exhaust system to achieve an even more emotionally appealing sound experience. The infinitely adjustable flaps modulate the exhaust note authentically and directly. The flaps open or close dependent on the selected AMG DYNAMIC SELECT driving mode, but can also be controlled individually with a separate button in the AMG DRIVE UNIT on the centre console. In the "Comfort" and "Sport" modes, the low-frequency sound typical of a V-8 emphasises comfort. In "Sport+“ it is of a much more emotionally appealing nature.

Systematic lightweight design: AMG Lightweight Performance

The stringent implementation of the AMG Lightweight Performance strategy also contributes to the high driving dynamics and low fuel consumption. The lightweight construction measures include the use of a lightweight lithium-ion starter battery, AMG forged light-alloy wheels as well as the weight-optimised AMG high-performance compound braking system. Furthermore, the entire outer skin of the S-Class including the roof and the front end of the body are made of aluminium. Installing a spare wheel recess made of carbon fibre, a material used in Formula 1 racing, reduces the weight by a further four kilograms.

Specially developed suspension for maximum lateral and longitudinal dynamics

The S 63 4MATIC+ is equipped with the AMG sports suspensions based on AIRMATIC with adaptive damping. Customers can preset the damping to the stages "Comfort“ or "Sport“ ‑ from relaxed long-distance comfort to dynamic sportiness. Rebound and compression are set independently of each other, which optimises the adaptation to the driving status and the quality of the road. The freely programmable mapping furthermore allows a wide spread between minimum and maximum damper forces. The difference between the comfortable and sporty suspension setting is thus more refined and is subjectively even more perceptible – depending on the particular driving situation.

Mercedes-AMG developed special front axle kinematics including a higher wheel camber, bigger stabiliser bar and more rigid subframe mount at the rear axle exclusively for the S 63 4MATIC+. These measures optimise the vehicle's agility when employing a spirited driving style. In conjunction with the newly developed front axle and the specially tuned all-wheel-drive system, the S 63 4MATIC+ represents a new dimension in driving dynamics in its segment.

S 65: AMG sports suspension based on MAGIC BODY CONTROL with curve-tilting function

The MAGIC BODY CONTROL suspension of the S 65 is focused on driving dynamics and prepares for bumps before the vehicle runs over them. To this end, MAGIC BODY CONTROL combines the active springs of the suspension with continuously adjustable dampers and ROAD SURFACE SCAN. The system precisely scans the condition of the road ahead with the help of a stereo camera to adjust the damping of each individual wheel optimally to the upcoming bumps already ahead of time.

The standard curve-tilting function causes the body of the vehicle to tilt to the inside of a turn by up to 2.65 degrees. This significantly reduces the perceived lateral forces and enhances the driving fun in particular on secondary roads.

Depending on the driving mode, the springing behaviour can be set to comfortable or sporty to suit personal preferences and/or the curve-tilting function can be activated. The active suspension effectively compensates body roll, squat and dive when moving off the line, in curves and during braking. The continuously adjustable dampers enable comfortable basic damping and a speed-dependent firm setting.

The ride height of the vehicle can be raised by 40 mm to increase the ground clearance. At high speeds, it is lowered by up to 15 mm and thereby reduces aerodynamic drag and increases the handling stability.

Direct and with clear feedback: the AMG speed-sensitive steering

The electro-mechanical speed-sensitive sports steering in the S 63 4MATIC+ and in the S 65 has a variable steering ratio. It stands out thanks to the AMG-specific rack-and-pinion ratio with its precise, highly authentic feedback. Power assist varies between the stages "Comfort“, "Sport“ and "Sport+“. The relevant characteristics are automatically activated depending on the selected DYNAMIC SELECT driving mode or can be personalised in "Individual" mode. At low speeds, the driver only needs to provide minimal steering input. At high speeds, he or she is able to rely on solid straight-line stability. The clearly defined steering centre and the authentic feedback likewise contribute to the optimum steering feel.

Good control and fade-resistant: the AMG high-performance compound braking system

The large high-performance compound braking system decelerates the performance saloon reliably and quickly, and is fade-resistant even under high stress. The S 63 4MATIC+ and S 65 are fitted with compound brake rotors of size 390 x 36 mm with 6-piston aluminium fixed callipers on the front axle, and of size 360 x 24 mm with single-piston floating callipers on the rear axle.

The AMG ceramic high-performance compound braking system is optionally available. The weight savings of more than 20 percent reduce unsprung masses and increase driving dynamics, agility and ride quality. Furthermore, the ceramic brakes are distinguished by a longer service life, higher corrosion resistance and higher thermal stability. It features brake discs of size 420 x 40 mm at the front and of size 360 x 32 mm at the rear. It can be identified visually by the "AMG Carbon Ceramic" lettering on the specially painted brake callipers.

The 3-stage ESP® offers more safety or more fun as desired:

• ESP® ON: for a high level of safety by adaptation to the sporty character of the car
• ESP® Sport Handling Mode: allows wider yaw angles before system intervention for a sporty driving style
• ESP® OFF: system deactivated for a sporty driving style on closed circuits. During hard braking, ESP® is switched back on temporarily.

Front apron with new jet wing: the exterior design

The new S 63 4MATIC+ and the new S 65 can be identified from the front by the MULTIBEAM LED headlamps and the redesigned front apron with expressive jet wing. The large side air intakes provide an improved airflow to the cooling modules – their functional form is familiar from motorsport. The three-dimensional front splitter reduces lift at the front axle.

The door sill panelling with three-dimensional high-gloss chrome inlays lower the S-Class visually closer to the road and create even more tension in the side. Typical for the AMG S-Class models are the large forged light-alloy wheels with a diameter of 19 inches as standard on the S 63 4MATIC+, and of 20 inches as standard on the S 65. The exclusive forged wheels of the V-12 saloon fascinate with their unusual design: each of the 16 spokes twists in a special way so that the light-catching contours radiate to the centre of the wheel hub. The effect: The wheel appears larger than its actual dimensions of 8.5 J x 20 at the front and 9.5 J x 20 at the rear. In addition, the ceramic mirror polishing ensure an exclusive look.

As standard, the forged wheels feature a high-quality, bolted and fully integrated wheel bolt cover made of forged aluminium. Its shape is reminiscent of a centre lock as seen in motorsport. The AMG logotype is incorporated into the rim as a design element. Three other forged wheels of the same size are optionally available – two design variants also painted matt black with a high-sheen rim flange.

The powerful rear end of the S 63 4MATIC+ and S 65 is formed by the updated rear apron with diffuser insert and the redesigned model-specific dual tailpipes of the AMG sport exhaust system. Additional stand-out features are the many high-gloss chrome design elements at the front, side and rear, which develop their radiant effect especially in combination with dark paint finishes.

Interior: beguiling appointments, design and quality

The stylish character of the new S-Class models from Mercedes-AMG is also evident in the interior: Both models welcome their passengers with an exclusive ambience. The AMG power sports seats with memory function and seat heating offer the driver and front passenger more lateral support. Nappa leather in AMG V-8 design with AMG badges in the front and rear backrests creates a luxurious atmosphere on board. Special touches include the embossed emblem on the armrest of the front centre console and the analogue clock in exclusive IWC design, which features three-dimensional, milled metal hands and genuine metal appliqués on the face.

The three-spoke Performance steering wheel features paddle shifters, a distinctly contoured rim trimmed with perforated leather in the grip area, and a metal insert with AMG logotype. It is optionally available made of black nappa leather/DINAMICA microfibre.

Another hallmark AMG speciality are the displays: The 31.2-centimetre TFT wide-screen colour display reproduces round dials that provide information about engine speed, vehicle speed and lots of additional data. The driver can choose from three display designs, Classic, Sport and Progressive. In addition, the AMG menu was expanded considerably. Among other things, it can display the engine and transmission oil temperature, lateral and longitudinal acceleration, engine output and torque, boost pressure, tyre temperatures and pressures as well as the current vehicle set-up.

Numerous options from the AMG Performance Studio

Anyone looking to customise the S 63 4MATIC+ and S 65 even further, can order a host of options from the AMG Performance Studio. The exterior can be tailored to personal preferences with the Night package, attractive alternative wheels and a Carbon package. In the interior, the black nappa leather/DINAMICA microfibre Performance steering wheel boosts the sporty character. Carbon or carbon/piano lacquer trim elements round off the possibilities.

AMG TRACK PACE App

Motorsport enthusiasts can record numerous vehicle data and lap times on the race track with AMG Track Pace in the S 63 4MATIC+. All values are shown on the COMAND display, and in the Widescreen Cockpit the current times can also be read off in the instrument cluster. Based on the data, drivers are able to analyse their driving style with precision and can use the insights gained to improve their lap times.

Affalterbach. Mercedes-AMG is once again extending its product portfolio with the addition of a very dynamic model: the new GLC 43 4MATIC Coupé* combines a sporty, elegant design with the brand's hallmark Driving Performance and the advantages of an SUV in terms of seating position, interior flexibility and also traction off the beaten track. The 270 kW (367 hp) 3.0‑l itre V6 biturbo engine, the automatic transmission 9G‑TRONIC with shortened shift times and the AMG Performance 4MATIC all-wheel drive configured with a rear bias form the basis for an especially dynamic on-road driving experience. A significant contribution is also made here by the independent sports suspension based on the multi-chamber air suspension system AIR BODY CONTROL with adaptive damping adjustment. Additionally, the GLC 43 4MATIC Coupé also enables occasional off-road excursions to be undertaken: the ground clearance can be increased at the touch of a button, and the pneumatic all-round self-levelling ensures a constant vehicle level at all times.   

"The new GLC 43 4MATIC Coupé is characterised by a high level of agility and sporty driving dynamics. With its expressive design and high everyday practicality the Coupé is able to appeal to new target audiences", according to Tobias Moers, Chairman of the Board of Management of Mercedes‑AMG GmbH.

The SUV Coupé fulfils a very wide variety of tasks with style: the unmistakable design stands out from the crowd without being overpowering, the sports car-like performance reveals the Coupé to be a thoroughbred performance car, and the convenience settings selectable at the touch of a button make it a reliable companion whatever the conditions. The GLC 43 4MATIC Coupé accelerates from rest to 100 km/h in 4.9 seconds and its speed is electronically governed at 250 km/h.

Spontaneous and powerful: the AMG 3.0-litre V6 biturbo engine

The 3.0-litre V6 biturbo engine is used in numerous AMG Performance models. It delivers a maximum output of270 kW (367 hp) plus maximum torque of 520 newton metres. Installed close to the engine, the two turbochargers are especially spontaneous in their response. The performance yield comes courtesy, among other things, of the boost pressure, which has been increased to 1.1 bar. The NANOSLIDE® coating of the cylinder liners is also used in the Formula 1 engines of MERCEDES-AMG PETRONAS. Especially tough and, therefore, wear-resistant, this coating also reduces friction, thereby contributing to higher efficiency. The same applies to the spray-guided multiple injection with up to 200 bar fuel pressure. Visually, the powerplant can be identified by the red aluminium insert in the engine cover and the AMG logo.

Short shift times, high efficiency: the 9G-TRONIC automatic transmission

The new GLC 43 4MATIC Coupé is equipped with the 9G-TRONIC automatic transmission, which Mercedes-AMG developers have specially configured for a more dynamic driving experience. They have managed to reduce the shift times of the 9-speed transmission by means of a dedicated software application. Courtesy of multiple downshifts, quick bursts of speed are possible with the 9G-TRONIC. Thanks to defined sparking manipulation, the double-clutching function allows more emotional and quicker gear changes in the "Sport", "Sport Plus" and "Manual" transmission modes.

"Manual" mode can be selected using a separate button in the centre console. The gear changes are based on the selected transmission mode, and the driver can now change gear using the standard-fit shift 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.

More agility: the sports suspension based on AIR BODY CONTROL

For added agility, more neutral cornering behaviour and higher traction even when driving at speed, the developers in Affalterbach have designed a dedicated sports suspension on the basis of the AIR BODY CONTROL full-support multi-chamber air suspension system. The four-link front axle is fitted with special steering knuckles and load-bearing joints; all components have been optimised in terms of rigidity. A more negative camber on the front axle and on the multi-link rear axle enhances lateral dynamics. The elastokinematics of both axles have been designed to be more rigid in general. The sum of these measures improve agility, and boost the dynamics.

The three-chamber air suspension system with a sporty spring/damper set-up and continuously variable damping adjustment combines excellent vehicle dynamics with a high level of ride comfort. The spring elements, which feature a composite design that is both light and strong, help reduce system weight compared with conventional air suspension.

The AMG developers have used a special matrix to define four spring rates, which are selected to suit the current transmission mode and driving conditions. In "Comfort" mode, the handling ranges from neutral to slight understeer. In "Sport" mode, the GLC 43 4MATIC Coupé handles significantly more dynamically with reduced roll thanks to the harder spring rate. "Sport Plus" mode delivers further enhanced agility and cornering ability due to the front and rear axles being sprung with different spring rates.

During sudden changes of load, fast cornering, heavy acceleration or hard braking, the spring rate is automatically made harder on the front or rear axle. This effectively reduces roll and pitching while stabilising the vehicle.

The adaptive damping adjustment also features in a model-specific configuration and offers a choice of the three modes "Comfort", "Sport" and "Sport Plus". This provides for broader scope between a high level of comfort on long journeys and sporty driving dynamics.

With the AIR BODY CONTROL suspension, the GLC 43 4MATIC Coupé is also suitable for occasional excursions into unpaved terrain: the vehicle level is not only permanently set to a constant height, it can also be increased at the touch of a button for more ground clearance – even while on the move. The fording depth of 300 mm and the approach angle of 19.8 degrees and departure angle of 20.8 degrees are evidence of the off-road capabilities of the SUV Coupé. It is equally suitable as a towing vehicle: it has a braked towing capacity of up to 2460 kg.

Rear-biased and agile: AMG Performance 4MATIC

The standard-fit AMG Performance 4MATIC all-wheel drive combines optimum traction, hallmark AMG vehicle dynamics and maximum driving pleasure. The system features a rear-biased torque distribution of 31 percent to the front axle and 69 percent to the rear axle. This arrangement ensures greater vehicle dynamics and higher lateral acceleration on the road as well as improved traction as it uses the dynamic shift in the axle load toward the rear axle that occurs during acceleration to deliver more drive torque to the rear. A multi-disc clutch with a locking effect of 50 Nm guarantees that the frictional connection potential of all four wheels is exploited to the full, particularly on snow and ice. On road surfaces with different levels of grip, the all-wheel drive responds with targeted brake application on one wheel in order to also guarantee optimum traction in such instances.

Characteristics at the tap of a finger: AMG DYNAMIC SELECT

With the five DYNAMIC SELECT transmission modes Eco, Comfort, Sport, Sport Plus and Individual, the characteristics of the GLC 43 4MATIC Coupé can be tailored to suit individual preferences at the tap of a finger. The broad range extends from efficient and comfortable to extremely sporty. This modifies key parameters, such as the response of the engine, transmission, suspension and steering. Independently of the DYNAMIC SELECT transmission modes, the driver has the option of pressing the "M" button to switch directly to manual mode, in which gearshifts are executed exclusively using the shift paddles on the steering wheel.

The DYNAMIC SELECT transmission modes "Sport" and "Sport Plus" are even more strongly configured for driving dynamics in the GLC 43 4MATIC Coupé than in the series-production models. This is thanks to the more agile, more direct accelerator characteristic and the more emotive gear shifting with shortened shift times, double-declutching function and cylinder shut-off. The higher idle speed also facilitates even faster moving off and acceleration from standstill.

In order to increase efficiency, in "Eco" mode the ECO start/stop function and the gliding function reduce fuel consumption: when the driver releases the accelerator in a speed range between 60 and 160 km/h, the clutch 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 "Comfort" mode provides for particularly comfortable motoring. To ensure maximum possible driving safety also in this mode, the spring and damper forces are instantaneously adjusted, for example in case of a sudden evasive manoeuvre.

Direct and with clear feedback: speed-sensitive sports steering

The speed-sensitive sports steering has a variable ratio in the GLC 43 4MATIC Coupé. It stands out with its precise, highly authentic feedback. Steering power assistance is adjusted in the two stages "Comfort" or "Sport". The relevant characteristics are automatically activated depending on the selected DYNAMIC SELECT transmission mode or can be personalised in "Individual" mode.

The large-sized braking system with internally ventilated compound brake discs decelerates the performance SUV Coupé reliably and quickly. Perforated discs in size 360 x 36 mm with 4-piston fixed callipers and AMG lettering are fitted on the front axle, while discs in size 320 x 24 mm with 1-piston fixed callipers feature at the rear.

Assistance systems such as Active Brake Assist, Crosswind Assist, Headlamp Assist, ATTENTION ASSIST or ESP®Curve Dynamic Assist enhance on-board safety as standard. Comfort and safety can be further enhanced with additional driver assistance systems.

Sporty and distinctive: the exterior design

The front view of the GLC 43 4MATIC Coupé reveals its independent character, with the diamond radiator grille with chrome pins and a louvre in high-gloss black with insert in high-gloss chrome and AMG lettering in high-gloss chrome. The sportily distinctive air intakes in the AMG front apron feature fins in silver chrome. Down below, the silver chrome front splitter ensures an optimal flow of air to the cooling modules.

Compared with the GLC 43 4MATIC, the A-pillar features a flatter slope angle. The squat greenhouse blends in seamlessly with the side of the vehicle to emphasise the coupé silhouette. The interplay between high beltline and wide shoulders results in proportions that lend the GLC Coupé its dynamic looks.

High-gloss black-painted, high-sheen 48.3 cm (19-inch) AMG 5-twin-spoke light-alloy wheels dominate the side view. The mixed-size tyres in the dimensions 235/55 R 19 on 8.0 J x 19 at the front axle and 255/50 R 19 on 9.0 J x 19 at the rear axle emphasise the powerful appearance. As an option, other combinations and designs are available, right up to 21-inch wheels in a bichromatic design.

The tail end also sports characteristic highlights and exudes sporty, aesthetic appeal with chrome-plated tailpipe trim elements in a four-pipe look. The AMG-specific rear apron sports trim in silver chrome. Narrow, divided tail lights and the sharp spoiler lip invoke the design line displayed for the first time with the S-Class Coupé and followed by all of the coupé models from Mercedes-AMG. The rear window dispenses with a wiper, as the airflow does not fall away until after the spoiler lip, which means that water is unable to strike the rear window.

Sporty characteristics: the interior design

The interior reinforces the consistently dynamic bias with numerous specially designed details. The colour combination of sporty, functional black with red contrasting features is a characteristic element. Longitudinal-grain aluminium trim highlights the sporty aspirations. The multifunction sports steering wheel in black leather with red contrasting topstitching and featuring a flattened bottom section is ideally suited to an emphatic driving style.

The driver and front passenger enjoy a secure position in the sports seats even when driving at speed, thanks to the improved lateral support. The upholstery in black ARTICO man-made leather/DINAMICA microfibre boasts its own seat upholstery layout plus red topstitching. To match the seat design, the door centre panels are styled in the same material. As a result, the standard-fit red designo seat belts also blend into the design. With two large round dials and central colour multifunction display with a 5.5-inch (13.97 cm) screen diagonal, the AMG instrument cluster places all the important information in the driver's field of vision. The ECO display supports a fuel-saving driving style. Dials in a chequered-flag look and the distinctive typography lend the large displays an especially sporty touch. Customers with a passion for motorsports will be pleased to note the RACE TIMER for recording lap times on closed-off tracks.

Flexible and spacious: the space conditions

For all its sportiness, the dynamic newcomer also impresses with some practical advantages. With a capacity of 491 to 1400 litres, the luggage compartment leads this market segment. Split-folding rear seat backrests, which fold down in the ratio 40:20:40, enable a variety of configurations to be used for particularly long or bulky items of luggage. And the availability of space in both front and rear is on a par with the GLC 43 4MATIC in terms of comfort level. Entrance height, shoulder room, elbow room and legroom are all identical.

Comprehensive: infotainment features

The standard infotainment equipment in the GLC 43 4MATIC Coupé includes the Audio 20 CD with 7-inch (17.8 cm) display, Frontbass, Bluetooth® hands-free function, audio streaming and two USB ports. The optional Garmin® MAP PILOT with Live Traffic expands Audio 20 CD into a fully-fledged navigation system with traffic jam avoidance integrated into the onboard electrical system. The navigation software and map data are supplied on an SD card.

When COMAND Online is installed, the colour media display features a screen diagonal measuring 8.4 inches (21.3 cm) and has an even higher resolution.
