Singapore - The AMG GT family welcomes its youngest member, the new Mercedes-AMG GT four-door Coupé. The four-door Coupé combines driving dynamics suitable for the racetrack with the high day-to-day comfort of a Gran Turismo, making it the perfect companion in any situation in life.
“The new Mercedes-AMG GT 4-Door Coupé is the perfect embodiment of race-bred performance and great practicality, an ultimate track weapon with the versatility of a four- door Coupe and a Gran Turismo which spearheads the AMG family." said Philipp Hagenburger, President and CEO, Mercedes-Benz Singapore.
Top-level longitudinal and lateral dynamics, and a striking silhouette with classic sports car proportions put the Mercedes-AMG GT 4-Door Coupé in the same portfolio as its two-door sibling at the very first glance. The expressive design with the front end drawn low down below the stretched bonnet, not to mention its muscular body, low greenhouse and powerful fastback highlights the sporty genes of the four-door Coupé.
The new 3.0-litre inline 6-cylinder petrol engine and the proven AMG 4.0-litre V8 biturbo engine covers a performance spectrum ranging from 320kW (435hp) to 470kW (63hp). They deliver incredible driving performance despite offering contemporary levels of efficiency. AMG-specific technologies such as the fully-variable 4MATIC+ all-wheel drive system and the rapid-shifting AMG SPEEDSHIFT 9G transmission with torque converter (TCT = Torque-Clutch Transmission) on six-cylinder models and a wet start-off clutch (MCT = Multi-Clutch Transmission) on eight-cylinder models serve to increase performance levels. As with the two-door AMG GT, the active aerodynamics with AIRPANEL active air control system in the front apron and extendible rear spoiler form the basis for high aerodynamic performance.
The interior is equipped with a number of modern high-tech features: innovative control panels such as the eight high-resolution display buttons in the centre console can be intuitively operated. The AMG Performance steering wheel with the new AMG steering wheel buttons, the AMG seats and the fully-digital Widescreen Cockpit with the new "Supersport" display style underscore the vehicle's dynamic character. MULTIBEAM LED headlamps, the EASY-PACK tailgate, Burmester® Surround Sound system and the 64- colour ambient lighting increase the car's everyday comfort.
The blend of high individualisation and sports car technology, placing yet more focus on the requirements of discerning customers, is also clear from the wealth of equipment packages and individual options. This is unique in the segment and includes, for example, three different configurations for the rear bench seat. Two individual seats in the rear are the standard equipment.
The high longitudinal and transverse dynamics come by virtue of systematic networking of all systems and components. The extremely rigid structure of the bodyshell also contributes to this, as does the sophisticated control strategy of the fully variable all-wheel drive system. Working together with the active aerodynamics, the active rear-axle steering (standard on the eight-cylinder model, optional for six-cylinder) and the integrated AMG DYNAMICS dynamic control system, the sophisticated suspension configuration comes fully into its own.
Production of the new Mercedes-AMG GT 4-Door Coupé started in September in hall 36 of the Mercedes-Benz Sindelfingen plant. The plant is the competence centre for vehicles of the upper and luxury segments. There, Mercedes-Benz produces the entire Mercedes-AMG GT family.
The V8 drivetrain of the AMG GT 4-Door Coupé is produced at AMG's engine manufacturing plant in Affalterbach in accordance with the "One Man – One Engine" principle.
Six and eight-cylinder units offering a broad performance spectrum
The exciting AMG 4.0-litre V8 biturbo engine is already used in a number of AMG models, where it delivers top-level, sporty performance. In the Mercedes-AMG GT 63 S 4MATIC+ it achieves a new performance peak of 470kW (639hp) and ensures superior sports car performance. The peak torque of 900Nm is available across a broad engine speed range from 2500 to 4500 rpm. As such, the top-of-the-line engine conveys a sense of absolute effortless superiority in all engine speed ranges. Acceleration from 0 to 100km/h in 3.2 seconds clearly illustrates this, as does the maximum speed of 315km/h.
The AMG 4.0-litre V8 engine works with the proven biturbocharging, where the two exhaust-gas turbochargers are arranged not on the exterior, but between the cylinder banks. The advantages of the "hot inside V" are the compact engine design and the immediate response of the exhaust-gas turbochargers.
Direct response: the two twin-scroll exhaust-gas turbochargers
To provide more power and even better responsiveness, the two twin-scroll turbochargers combine optimal responsiveness at low engine speeds with high performance gains at higher revs. In addition to this, the turbine housing is divided into two flow passages which run parallel to one another. Combined with two separate ducts in the exhaust manifold, this makes it possible to individually control the momentum of the exhaust gases acting on the turbine wheel.
The exhaust gas from the first and fourth cylinders of the cylinder bank is fed into one duct, while the exhaust gas from the second and third cylinders is fed into the other duct. The aim is to prevent the individual cylinders from having mutually adverse effects on the gas cycle. This reduces the exhaust gas back pressure and improves gas exchange. The results are increased output due to improved cylinder charge with fresh mixture, more torque at low revs and very immediate response times.
To enhance performance, compressor and turbine wheels which have been optimised for efficiency are used in the two twin-scroll turbochargers. The geometry of the compressor and turbine blades has been adopted from the latest generation of turbochargers.
What's more, this is the first time that the compressor wheel and turbine wheel are fitted with ball bearings. Thanks to the ball bearing, mechanical friction of the wheel assembly in the turbocharger is reduced to a minimum. The turbocharger therefore responds more spontaneously and achieves high speed more quickly.
Further features of the V8 engine are spray-guided direct petrol injection with piezo injectors, the all-aluminium crankcase, the four-valve-per-cylinder design with camshaft adjustment, air-water charge air cooling, alternator management, the ECO start/stop function and the gliding mode – all of which have been retained.
Improved efficiency: the intelligent AMG Cylinder Management
For maximum efficiency, Mercedes-AMG has also equipped the V8 engine with the AMG Cylinder Management cylinder deactivation system. In the partial-load range, cylinders two, three, five and eight are deactivated, which crucially reduces the fuel consumption.
When the driver has selected the "Comfort" drive program, the cylinder shut-off system is available in the wide engine speed range from 1000 to 3250 rpm. A special display on the instrument cluster indicates whether the cylinder deactivation system is in use and whether the engine is presently operating in four or eight-cylinder mode. The transition between these two operating states is immediate, fast and torque-neutral, so the passengers do not have to relinquish any comfort.
In the AMG GT 63 S variant, the eight-cylinder unit is also equipped with dynamic engine mounts as part of the standard AMG DYNAMIC PLUS Package. The mounts solve the conflicting goals of achieving as soft a connection as possible to the powertrain for high comfort and as rigid a connection as possible for optimum driving dynamics, by steplessly and quickly adapting their rigidity to the respective driving conditions.
Efficient and multifaceted: six-cylinder engine with hybrid functions
Alongside the V8 engine, the new four-door sports car is also available with the new 3.0- litre inline six-cylinder engine for the AMG GT 53 4MATIC+ model. The 320kW (43hp) powerful units are characterised by superior power delivery, exemplary smooth running and contemporary efficiency. The integrated EQ Boost starter-alternator provides assistance in the form of up to 16kW (22hp) more power and 250 Newton metres more torque. It unites a starter motor and an alternator in a single, powerful electric motor integrated between the engine and the transmission.
This intelligent combination along with efficient charging by means of the electric auxiliary compressor and the turbocharger helps ensure the hallmark AMG performance and driving dynamics but also cuts consumption and emissions at the same time. The AMG GT 53 4MATIC+ accelerates from 0 to 100km/h in just 4.5 seconds and can reach a top speed of 285km/h,
More energy for even more innovations: the new 48-volt on-board power supply
The EQ Boost starter-alternator in the new AMG GT 53 also generates the power for the 48 V on-board electrical system. This in turn uses a DC/DC converter to supply the conventional 12 V network for the lights, cockpit, infotainment displays and control units. Through the 48 V battery, the battery capacity of the entire car is increased, which means that more electrical energy can be made available for new functions. The 48 V on-board electrical system thus also paves the way for the progressive expansion of infotainment and assistance systems.
With wet start-off clutch or torque converter
Power transmission is handled by the AMG SPEEDSHIFT 9-speed automatic transmission which combines an emotive shifting experience with extremely rapid shift times. In the case of the V8 power units, the wet start-off clutch reduces weight and optimises responsiveness. The transmission of the six-cylinder version features a torque converter.
The AMG SPEEDSHIFT MCT 9G (MCT = Multi-Clutch Transmission) is specially tuned for the requirements of the eight-cylinder variant of the four-door AMG GT. A wet start-off clutch is used here. This saves weight and, as a result of its low inertia, optimises the response to the driver's accelerator pedal input, particularly during acceleration and load changes.
The complex and fine-tuned software ensures extremely rapid shift times as well as quick multiple downshifts where required. Thanks to the double de-clutching function in the "Sport" and "Sport+" drive programs, the system delivers an especially emotive shift experience. Here, defined ignition adjustments enable even faster gearshifts than in the other modes. In all modes, moving off occurs in first gear in order to always guarantee a dynamic driving experience. There is also the RACE START function which ensures optimum acceleration from a standstill.
The inline 6-cylinder engine is coupled with the AMG SPEEDSHIFT TCT 9G (TCT = Torque- Clutch Transmission) transmission. In conjunction with the torque converter, the automatic transmission is tuned to the special requirements of this engine. On the one hand, this guarantees maximum comfort during pulling away and shifting, while on the other, it allows for AMG-typical rapid and emotive shifting to suit the selected drive program.
Fully-variable all-wheel drive
In order to deliver the high engine output with maximum traction and dynamism in all situations, the AMG GT 4-Door Coupé models are equipped with AMG Performance 4MATIC+ all-wheel drive.
The electro-mechanically controlled clutch of the AMG Performance 4MATIC+ all-wheel- drive system 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 transition from rear-wheel to all-wheel drive and vice versa is seamless, as the intelligent control is integrated into the overall vehicle system architecture. Alongside traction and lateral dynamics, the all-wheel drive also improves the longitudinal dynamics for even more powerful acceleration.
It is still possible to drift thanks to fully variable torque distribution. To this end, the S version of the four-door AMG GT features Drift mode as standard. It is also available for other models as part of the optional AMG DYNAMIC Plus Package. Drift mode can be called up in the "RACE" drive program using the shift paddles, provided that ESP® is deactivated and the transmission is in manual mode.
Up to six options suitable for all types of driving
Depending on the engine, there are up to six AMG DYNAMIC SELECT drive programs to choose from in the four-door AMG GT: "Slippery", "Comfort", "Sport", "Sport+", "Individual" and "RACE". These programs can be set using the switch in the centre console or the AMG steering wheel buttons and can additionally be assigned AMG DYNAMICS attributes. As a result, the driving characteristics can be more greatly differentiated in line with various demands and driving conditions.
The AMG DYNAMIC SELECT drive programs adapt important parameters such as the responsiveness of the engine and transmission, the characteristic curve of the steering, the suspension damping or even the vehicle's sound. The programs are selected using the paddle in the centre console or the AMG steering wheel buttons and are then visualised in the instrument cluster and on the multimedia display.
• "Slippery": optimised for slippery road conditions, with reduced power and a flat torque curve.
• "Comfort": comfortable and fuel-efficient driving, e.g. thanks to very early upshifts. Suspension and steering are set up for an emphasis on comfort.
• "Sport": sporty characteristics thanks to a more agile response to the driver's accelerator pedal input, shorter shift times, earlier downshifts and significantly more emotive gearshifts owing to double de-clutching. A more dynamic suspension and steering setup.
• "Sport+": extremely sporty characteristics thanks to an even more agile throttle response, increased acoustic emphasis on double de-clutching during downshifts as well as selective torque control on upshifts with cylinder suppression for optimal shift times. Increased idle speed for faster pulling away. An even more dynamic setup for suspension, steering and drivetrain.
•"Individual": individual adjustment of the drive system, transmission, AMG DYNAMICS, suspension and exhaust system.
• "RACE": the AMG GT 63 S 4MATIC+ additionally features as standard the "RACE" drive program for highly dynamic driving on closed race tracks. In this program, all of the parameters are configured for maximum performance. It is also available for the other model as part of the optional AMG DYNAMIC PLUS Package.
Even more differentiation in driving experiences: AMG DYNAMICS
As a new feature within the AMG DYNAMIC SELECT drive programs, the AMG GT 4-Door Coupé also includes AMG DYNAMICS. This integrated driving dynamics regulation influences the control strategy of ESP® (Electronic Stability Program), the all-wheel-drive system, the rear-axle steering (standard on V8 model) and the electronically controlled rear-axle differential lock (standard on V8 model). This increases agility without negatively affecting the vehicle's stability.
Particularly remarkable: AMG DYNAMICS determines how the vehicle should react. The system uses the available sensors, among other things, to ascertain the speed, lateral acceleration, steering angle and yaw rate. Thanks to an intelligent pilot-control principle, it is possible to anticipate how the driver wants the vehicle to behave, based on the driver's actions and on data from the sensors. Regulation is tailored to the dynamic driving competence of the driver – without any noticeable or disruptive interventions by the system. The driver gets a very authentic driving feel with high cornering dynamics and optimum traction as well as high stability and predictable handling. Even experienced drivers receive optimum assistance without feeling patronised by the system.
The spectrum ranges from extremely stable to highly dynamic. On the multimedia display, when a drive program is selected, the new AMG DYNAMICS symbol is displayed together with the corresponding additional information.
• "Basic" is assigned to the "Slippery" and "Comfort" drive programs. Here the AMG GT demonstrates exceptionally stable handling characteristics with high yaw damping.
• "Advanced" is activated in the "Sport" programme. The four-door Coupé maintains a neutral balance. The lower yaw damping, lower steering angle requirement and enhanced agility support dynamic manoeuvres such as driving on winding country roads.
• "Pro" (short for "Professional") belongs to the "Sport+" program. In "Pro" the driver receives even more assistance for dynamic driving manoeuvres while agility and feedback from the road when cornering are further enhanced.
• "Master" is coupled with the "RACE" drive program. "Master" mode is aimed at drivers who want to experience dynamism and the driving enjoyment on closed-off circuits. "Master" offers a vehicle balance with slight oversteer, a low steering angle requirement and more agile steering. In this way, "Master" ensures maximum agility and optimally exploits the dynamic potential of the "S" version. To activate "Master" mode, the driver must use the separate button in the centre console to switch the ESP® to ESP® SPORT Handling Mode or ESP® OFF.
In the "Individual" drive program, the driver can set the AMG DYNAMICS levels "Basic", "Advanced", "Pro" and "Master" themselves.
Irrespective of the drive programs, as before it is possible to use the display buttons in the centre console to directly select manual transmission mode, the favourite suspension level and exhaust system settings.
Numerous motorsports elements ensure dynamic driving
The high agility and race track-oriented driving dynamics of the four-door AMG GT are also down to the special AMG suspension. In the case of the six-cylinder model, the AMG RIDE CONTROL suspension with steel springs and the Adaptive Damping System are used. The AMG RIDE CONTROL+ suspension of the eight-cylinder variants is based on the full-support multi-chamber air suspension, also combined with the Adaptive Damping System. A rigid integral carrier bears the front axle, engine, transmission and steering gear.
The front axle is a 4-link construction. In conjunction with the wide track width and large tyre dimensions, wheel location and spring elements which are independent of one another facilitate high lateral acceleration, whilst the low unsprung masses promote the agile driving sensation even further. The oversteer/understeer characteristics deliver neutral to slight understeer bias.
The torque strut, spring link and wishbone are all made of forged aluminium and thus save weight and improve driving dynamics. Even the steering knuckle, specially tuned for the Mercedes-AMG GT 4-Door Coupé, as well as the rigid integral carrier for the mounting of the front axle, engine, transmission and steering gear are weight-optimised. By decoupling the chassis from the body, it also contributes to increased camber stability and the high level of noise comfort on-board.
Optimum traction: multi-link rear suspension with differential lock
The multi-link rear suspension with five links makes for impressively precise suspension and high rigidity. Here again, the consistent implementation of a lightweight construction leads to reduced unsprung masses: three of the five wheel-guiding links as well as the wheel mounts are made of forged aluminium. The driving dynamics benefit from the increased track width, the larger tyre dimensions and the optimised fine-tuning of the wheel-guiding elastomer bearings. Newly developed elastokinematics guarantee everyday comfort as well as high-precision driving and great vehicle dynamics.
To improve traction and dynamics, the eight-cylinder model is equipped as standard with an electronically controlled differential lock on the rear axle. The slip is thus suppressed at the inner wheel on bends, ensuring optimum grip. The driver is therefore able to accelerate out of corners earlier and with more power thanks to the improved traction. The vehicle remains more stable when braking from high speed, while the limited-slip differential also improves traction when accelerating from a standstill. The electronically controlled rear- axle differential lock is also part of the optional AMG DYNAMIC PLUS Package and is available in this way for the six-cylinder model of the four-door AMG GT.
The rear-axle differential also has a new specially reinforced mount to improve the NVH (noise, vibration, harshness) characteristics. As on the AMG GT R, an anti-roll bar made of tubular material reduces the overall weight of the rear axle.
The Adaptive Damping System works dependent on the selected drive program, but can also be individually actuated using the display button in the centre console, where the three stages "Comfort", "Sport" and "Sport+" can be individually selected. The driving sensation which these deliver ranges right from relaxed long-distance comfort to maximum sportiness. The rebound and compression levels are adjusted independently of each other, and the freely programmable maps permit a wide spread between minimum and maximum damper force. The difference between the comfortable and sporty suspension settings is thus more refined and is even more perceptible – depending on the particular driving situation.
A new dimension of the individually configurable driving experience is made possible by the AMG RIDE CONTROL+ three-chamber air suspension system and its sporty spring and damper setup. It combines exemplary driving dynamics with increased rolling comfort. The rigidity of the air springs can be fine-tuned by activating or deactivating individual air chambers. This results in a tangible increase in comfort, as well as having a positive effect on handling.
By carrying out extended trials and test drives, the developers at AMG have defined three spring tuning settings which are actuated depending on the selected drive program and actual driving conditions. During sudden load changes, fast cornering, heavy acceleration or hard braking, the spring rate is also automatically made harder on the front or rear axle, as appropriate. This effectively reduces roll and pitching movements.
In the "Comfort" program, the air suspension is oriented towards providing a very comfortable ride. Irregularities in the road surface are absorbed and the four-door model travels smoothly. In "Sport", the Coupé drives much more dynamically thanks to a stiffer setup and less roll. In "Sport+", agility and the desire to take corners are more drastically increased as the front and rear axles are sprung even stiffer.
Enhanced agility and precision: the active rear-wheel steering
The AMG GT 4-Door Coupé responds even more sensitively to steering commands thanks to the active rear-axle steering which comes as standard in the V8 model and is also available in the six-cylinder version as part of the optional AMG DYNAMIC PLUS Package. The system delivers an even better combination of agility and stability and thus reinforces the dynamism and handling safety of the new four-door AMG GT.
Up to a speed of 100km/h, the rear wheels point in the opposite direction to the front wheels with the aid of two electric actuator motors. As a result, the car turns into corners with significantly higher agility. Under everyday driving conditions, the driver also benefits from a smaller turning circle.
At speeds higher than 100km/h, the system turns the rear wheels in the same direction as the front wheels. This noticeably improves driving stability. At the same time, the lateral force on the rear wheels builds up considerably faster during changes of direction, thus improving the response to the steering. The driver can also rely on extreme rear-axle grip and high stability when changing direction quickly.
Direct and immediate: AMG speed-sensitive sports steering
The electromechanical speed-sensitive power steering has a variable ratio. It impresses with its precise feedback thanks to the AMG-specific rack-and-pinion steering with a variable ratio. Power assistance also varies between the three stages "Comfort", "Sport" and "Sport+". The appropriate characteristic is automatically activated depending on the selected AMG DYNAMIC SELECT drive program or can be personalised as required in "Individual" mode.
Good control and fade-resistant: the high-performance composite brake systems
In line with the high output values and their associated performance, the eight-cylinder model have a large-dimensioned brake system consisting of internally-ventilated, perforated composite discs at both the front and rear axles, with 6-piston fixed callipers used at the front and single-piston floating callipers at the rear. The six-cylinder model is also equipped with internally-ventilated, perforated composite disc brakes at the front.
As an option, an AMG high-performance ceramic composite brake system with bronze- coloured 6-piston fixed callipers at the front and single-piston floating brake callipers at the rear can be ordered. This leads to additional weight savings and lower unsprung masses. Further advantages are their even greater overall sturdiness and fading stability under high stress. The brake system also wins points with a high service life and immediate response – guaranteeing fast lap times.
All brake systems can impress with short brake paths, sensitive responsiveness and high life expectancy, even in the case of extreme stress. Among the comfort features of the vehicle are hill start assist, priming and dry-braking in the wet. With the ignition switched off and the vehicle at a standstill, the transmission automatically selects Park position "P". Meanwhile, the electric parking brake releases automatically when pulling away.
Lightweight construction principle
High percentage of aluminium and carbon-fibre components
An aim during development of the new four-door AMG GT was to create a rigid body shell which would serve as the basis for high levels of driving dynamics. In order to do this, analysis and simulation methods from racing were used in order to reinforce the structure in the relevant places to ensure maximum performance. The body-in-white is based on a highly rigid structure made using hybrid constructions in steel, aluminium and carbon fibre. This intelligent mix of materials harmoniously unites an array of different requirements: low weight, greatest possible structural rigidity as well as the best-possible crash safety and long-term bodywork quality.
The very rigid front section prevents unwanted distortions about the longitudinal and lateral axes, which ensures precise steering behaviour and better feedback for the driver. Here, a further-developed modular concept was implemented which was previously only used in Cabriolets. A so-called "shearing plate" – an aluminium plate underneath the engine – increases the torsional rigidity at the vehicle's front end. In addition, stiffening struts made of steel are also used. In the centre section of the vehicle, the struts are made of aluminium. The rear of the car is reinforced by means of a package of struts in steel. All measures, as well as the close networking with the chassis development team in the development phase provide the optimal basis for high lateral dynamics.
Hybrid construction principle with an intelligent materials mix
The lightweight concept is based on a hybrid construction principle with an intelligent materials mix of steel, aluminium and carbon fibre, as part of which special joining processes improve the quality of the joints between the various materials. The bonnet and wings, for example, are made of aluminium. Cast aluminium nodes in the C pillar strengthen the rear area. The rear wall (in the case of the standard rear seats without folding backrests) and the boot cavity are made of light and highly rigid carbon fibre.
The core of the body's safety concept is the highly rigid passenger cell. In the structure areas which are subject to especially high loads, hot-stamped, ultra-rigid steels are used to provide the best-possible crash performance, while deformable load path structures absorb energy in the front and rear crumple zones.
Typical AMG GT proportions and dynamics
As a member of the AMG GT family, the new AMG GT 4-Door Coupé follows the design philosophy of Sensual Purity. It picks up on the striking proportions, the convex surfaces and the muscular body of the two-door variant and further develops these into the characteristic shape of the four-door version. The flowing silhouette with low greenhouse and dynamic fastback underscores the sporty focus.
The front end is markedly dynamic with its broad, low-drawn "shark nose", filigree MULTIBEAM LED headlamps with carbon-fibre elements, AMG-specific radiator trim and front apron featuring further-developed jet wing (with flowing A wing in the case of six- cylinder model). The heavily contoured powerdomes on the long bonnet allude to the powerful unit housed underneath it, while the broad wings make the dynamic potential of the AMG GT 4-Door Coupé distinctly visible. As with the two-door AMG GT models, a radiator blind, the so-called AIRPANEL, positioned in front of the central radiator air inlet improves the vehicle's aerodynamic efficiency according to requirements. The striking front splitter reduces lift on the front axle.
Characteristic Coupé architectural features include the frameless side windows and the flat windscreen which is drawn widely towards the rear. Even from the side perspective, the "shark nose" design looks especially dynamic and feisty. The tapered side line and the broad shoulders hint at the athletic and sporty orientation of the vehicle. Depending on the engine version, the heavily pronounced wheel housings are home to a broad range of 19 and 20-inch light-alloy wheels, not to mention optional 21-inch forged wheels, all of which provide a high degree of personalisation.
The broad and flat rear end takes up the characteristic design elements of the AMG GT design idiom: extremely narrow LED tail lamps with dynamic turn signal indicators define the typical load sill, whilst the third brake lamp in the upper area of the rear window and the rounded rear window itself underline the vehicle's sporty Coupé character. The multi- stage extendible rear spoiler doesn't just signal its family origin, but it is also an important component of the car's active aerodynamics. As part of the optional Aerodynamics Package, a fixed rear wing is available in either high-gloss black or carbon-fibre look. Further design elements include the diffuser and twin tailpipe trims fixed on the outer edges.
The tail lamps feature so-called multi-level functionality: the brightness of the LED brake lights is, for example, dimmed when waiting at a red traffic light.
Differentiation of the V8 model underlines the sporty character
The design of the V8 model is made even more powerful through the addition of various details such as the lower and wider design of the front and rear aprons. From the front, the AMG GT 63 S is characterized by the splitter which is additionally in silver shadow as opposed to being painted in the vehicle's body colour.
From the side, the tapered side sills highlight the slender, muscular vehicle body; the additional sill inserts further underline the vehicle's sporty character. Wider and lower proportions at the rear end make the vehicle look as if sits more firmly on the road.
Compared to the six-cylinder model, the striking diffuser with larger shaped fins and directly connected diffuser blade increases the downforce at the rear axle and also features a trim element in high-gloss black (AMG GT 63 S in silver shadow). The V8 model is equipped with twin trapezoidal tailpipe trims while the six-cylinder variants can be recognised by their round twin tailpipe trims.
A particular highlight comes in the form of the new, optional AMG light show which welcomes passengers by projecting the AMG logo onto the ground in front of the doors.
Fine-tuned interplay of active elements
A significant contribution towards the high driving dynamics and handling safety of the AMG GT 4-Door Coupé is made by the active aerodynamics, which have been tuned to the special requirements of the four-door Coupé in extensive simulations, wind tunnel tests and road testing. The main components of the complex aerodynamics concept are the AIRPANEL active air control system in the front apron, the compact, multi-stage retractable and extending rear spoiler, and the aerodynamic rim designs.
The intelligent interaction of the active aerodynamics features ensures the optimum combination of power output and low wind resistance. As part of this, the system reacts to the respective driving situation and the vehicle settings selected by the driver, varying the position of the rear spoiler appropriately to the computed optimum position.
AIRPANEL is made up of 20 vertically installed fins located in the lower section of the front apron. These electronically controlled blinds are opened and closed very quickly by an electric motor in order to steer the air flow and thus ensure the aeroperformance and necessary engine cooling requirements are met.
Active rear spoiler for more driving stability and dynamism
The active rear spoiler changes its position depending on the driving characteristics. In doing so, the control software takes into account numerous parameters: it evaluates the vehicle speed and lateral acceleration, reacts to the switch position for the AMG DYNAMIC SELECT drive program and also takes into account the separate, manual switch for the rear spoiler.
From a speed of 80km/h, the spoiler adopts different heights in order to either optimise the driving stability, reduce the air resistance or increase the top speed. If the system detects lateral dynamics, the spoiler moves into the most steep Dynamic position and thus ensures both dynamic and safe driving.
• Position 0, 0mm height
-V8 and inline 6-cylinder 0 - 80km/h: Fully integrated into the design of the tailgate, the rear spoiler makes for a clean visual appearance at a standstill and at low speeds. When parked, the positioning mechanism is protected against dirt and foreign bodies.
• Position 1, 65mm height
-V8 and inline 6-cylinder 80 - 140km/h: In this position, the AMG GT 4- Door Coupé demonstrates the lowest air resistance (lower than in position 0), thus delivering the best-possible efficiency.
• Position 2, 130mm height
-V8 140 - 180km/h: Optimal balance between low air resistance and driving stability from the mid road speed range.
- Inline 6-cylinder 140km/h - Vmax: Optimal balance between low airresistance and driving stability right up to the vehicle's top speed. Position 3, 160mm height
- V8 180km/h - Vmax: Optimal balance between low air resistance and driving stability right up to the vehicle's top speed.
- Inline 6-cylinder Performance position, 180 - 240km/h, only in the drive programs "Sport+" and "RACE": Optimal performance thanks to increased downforce when cornering or braking.
- Inline 6-cylinder Spoiler also extends to position 3 if the display button in the centre console is pressed.
• Position 4, 172mm height
-V8 Performance position, 180 - 260km/h, only in the "Sport+" and "RACE" drive programs: Optimal performance thanks to increased downforce when cornering or braking.
-V8 Spoiler also extends to position 4 if the display button in the centre console is pressed.
• Position 5, 182mm height
- V8 and inline 6-cylinder Dynamic position, 120km/h - Vmax, when the vehicle detects highly dynamic driving: Maximum lateral dynamics with greatest possible downforce providing for the best-possible road-holding. Simultaneously the greatest driving stability.
For the AMG GT 4-Door Coupé, there are also a range of aerodynamically optimised 19- inch light-alloy wheels available which create less turbulent air flow and thus reduce air resistance.
Added downforce: the optional Aerodynamics Package
As an exclusive in its market segment the new AMG GT 4-Door Coupé can also be equipped with an Aerodynamics Package on request. It comprises a larger front splitter and additional flics on the lateral air inlets of the front apron, an even more aerodynamically optimised diffuser and a fixed rear wing. The wing's blade can be mechanically adjusted in order to adapt the vehicle to the conditions of various race tracks, for example. What's more, there are also guide elements on the lateral air inlets of the rear wings.
Compared with the other model's adjustable rear spoiler extended to the full, at 300km/h, the rigid variant pushes the rear axle down onto the road surface with an additional 30 kilogrammes of aerodynamic force. The larger front splitter also reinforces the effect of the AIRPANEL active air management system: if the adjustable blinds are closed, the lift at the front axle is further reduced.
Another advantage of the complex work that has gone into this package: despite the increased downforce, the air resistance is even lower than on the variant equipped with the adjustable spoiler.
Incredible inner values
The interior of the AMG GT 4-Door Coupé stuns thanks to its sporty ambiance and generous feeling of spaciousness. It presents itself as a symbiosis of performance and exclusivity, integrating the conspicuous AMG Drive Unit in V8 styling with ultra-modern, innovative operating concept into a Gran Turismo ambiance. Depending on the equipment level, either two or three passengers can sit comfortably in the rear of the four-door Coupé. Different design and equipment packages offer a wide range of scope for personalisation.
The sculpted instrument panel in the cockpit of the AMG GT 4-Door Coupé forms an interesting contrast to the large trim element with its flowing style, which merges into the driver's door in a wrap-around effect. 64-colour ambient lighting, ten colour worlds and two different effects which also include the illumination of the turbine-look air vents round off the high quality impression. One clearly visible characteristic is the centre console in V8 design featuring innovative display buttons which offer a novel and ground-breaking operating experience.
Two high-resolution 12.3-inch displays dominate the Widescreen Cockpit which comes as standard for both models. The surface is formed by a bonded glass cover, as familiar from expensive smartphones and tablets. Three different styles are available for selection for these all-digital displays: "Classic", "Sport" and "Supersport". The different styles can be changed at any time using the Touch Control buttons on the steering wheel.
The digital speedometer of the six-cylinder vehicles features a 330km/h scale, whilst the scale of the V8 model reaches as far as 360km/h. The standard instrument cluster for the six-cylinder versions features round analogue instruments in a two-tube design: the speedometer with a 320km/h scale is on the left, and the rev counter with AMG logo can be found on the right. The AMG main menu including RACETIMER is shown in high- resolution on the central 7-inch multifunction TFT colour display. As an option, a Head-up Display is also available. It projects an approximately 21 x 7 cm image featuring the most important driving data into the driver's field of vision.
Via the left-hand Touch Control button on the steering wheel, preferred information can be shown on the left or right-hand side of the instrument cluster – for example the classic speedometer and rev counter, information on navigation or assistance systems and even detailed engine data. Especially sporty drivers can also display the lateral acceleration or the current output and torque values.
In the "Supersport" view there is also extensive additional AMG-specific information, such as a prominent prompt to change up a gear ("shift light") in manual transmission mode, reminiscent of those found in motorsports.
The central display represents the interface to all further content and information, such as navigation, radio, media, telephone and vehicle data.
The large full-screen map view ensures optimum legibility in all driving situations. There are also extra performance-oriented functions, such as visualisation of the all-wheel drive.
With additional functions as an option: the new performance steering wheel
The new AMG Performance steering wheel in sporty 3-spoke design blends ideal ergonomics with maximum functionality. It features a flattened bottom section and high- grade aluminium shift paddles as well as a 12 o'clock marking. Various functions are clubbed together in groups and can be precisely and intuitively operated via the Touch Control buttons on the steering wheel. The driver controls the entire infotainment system using finger swipes, without having to take their hands off the steering wheel.
The AMG drive programs can be actuated directly via the controller. The selected drive program is shown on the colour TFT display directly integrated in the controller.
With the two freely configurable display buttons and the additional AMG switches, further AMG functions can be controlled ergonomically and directly on the steering wheel. This means that the driver can concentrate fully on dynamic driving without having to take their hands off the wheel. Each desired function can be depicted on the other TFT display, and the designated switch can be tapped by the driver to set the respective function. The driver's two preferred AMG functions can be defined in this way and the settings changed with just one tap of the finger.
As standard, the steering wheel comes in black nappa leather. Other optional variants see the use of black microfibre either in just the grip area or all-round (as part of the AMG DYNAMIC PLUS Package) as well as carbon-fibre or black piano lacquer in the upper and lower sections of the steering wheel rim, thus providing a range of additional personalisation options and much greater motorsport flair.
Display buttons in the innovative centre console
Inspired by the two-door Mercedes-AMG GT, the centre console of the new 4-door model is yet another special feature. A new and unique feature comes in the form of the colour display buttons, integrated into the distinctive and tailor-made trim element. These allow the simultaneous display and control of the transmission logics, suspension, ESP®, exhaust system, start/stop function and rear spoiler. With their TFT technology the display buttons use colour, intuitively comprehensible symbols to show the function and are easy to operate with just a small tap of the finger. They are supplemented by the two rocker switches for drive program selection and volume regulation.
Comfortable, sporty, spacious: the front seats
The AMG GT 4-Door Coupé uses a lightweight seating concept, as one would expect from its sports car character. Here, too, Mercedes-AMG proves that comfort and exclusivity are not diametric opposites to a performance-oriented vehicle setup and high safety levels – for example thanks to their 4-stage adjustable head restraints and the strong side bolsters which deliver greater lateral support. The comfortably ergonomic basic construction with high seat backrest makes possible an especially comfortable shoulder area, while the seat adjustment range and diverse variability of the parameters for the seat cushion, for example, allow the legs to be stretched out more easily. The high-quality hand-crafting and especially independent character result, among other things, from the electroplated trim with AMG lettering in the seat backrest or the attractive colour selection with fine details such as the colour-contrasting topstitching and piping.
There are various configurations available for the driver's and front passenger seats. This ranges from AMG seats in ARTICO man-made leather/black microfibre (or nappa leather for the eight-cylinder model) right up to the highly contoured AMG Performance seats with integrated head restraints. Six independent equipment concepts with exclusive colour concepts are available to choose from. They can be combined with various trim elements and equipment. Numerous items of optional equipment further increase comfort and dynamism. Among these, the seat climatisation function for driver and front passenger including seat heating and seat ventilation. There is also the Multicontour Seat Package with electro-pneumatic 4-way lumbar support and controls directly on the seat, electric seat cushion angle adjustment, mechanical seat cushion length adjustment as well as active cushions for adjustment of the lateral support provided by the seat backrest and cushion.
Tailor-made space concept: optionally with four or five seats
The Mercedes-AMG GT 4-Door Coupé is a true sports car. The space and comfort which it offers combine sportiness and everyday usability. This also applies to the second row of seats where different seating configurations fulfil a diverse range of demands.
• As local standard, it is equipped with three-seater rear bench seat with 40:20:40 split-fold.
• When equipped with the optionally available High-Class Rear Seats, the rear passengers can select diverse features via a touchpad screen integrated into the console between the seats. The features range from calling up the dynamism data via the AMG menu to controlling the ambient lighting or the climate control and seat heating.
The boot volume of 456 litres can be increased to 1324 litres by folding forwards the seat backrests. The wide load compartment opening makes it easier to load and unload luggage and other items. As an option, the large tailgate can be opened and closed with the HAND- FREE ACCESS feature by moving the foot underneath the bumper.
Always in touch thanks to connectivity and Intelligent Drive
For high comfort in everyday use, the new four-door sports car from Affalterbach boasts all the connectivity and Intelligent Drive functions and driving assistance options of the Mercedes-AMG S-Class. These include partially automated driving with the DRIVE PILOT, which can support the driver with routine daily tasks such as driving in a traffic jam.
The vehicle as a virtual race engineer: AMG TRACK PACE
AMG TRACK PACE captures and analyses in detail over 80 vehicle-specific data as well as times on the racetrack. The AMG TRACK PACE is an additional function of the COMAND Online infotainment system and is part of the standard equipment for the AMG GT 4-Door Coupé.
Data collected on lateral and longitudinal acceleration, the accelerator and brake pedal or steering angle help record and continuously improve individual Driving Performance. All the values are shown on the COMAND display, on request also in real time on the telemetry screen. Thanks to the different colours and acoustic feedback used, faster or slower laps
can be spotted out of the corner of the driver's eye without any need to look away from the track. Even the drift angle of the car is calculated and displayed. As well as recording drives on circuits, AMG TRACK PACE can also be used to register acceleration such as the sprint from standstill to 100km/h or over a quarter of a mile as well as deceleration values.
Fuel for the senses
The interior of the new Mercedes-AMG GT 4-Door Coupé has another world premiere in store. For the first time, as part of the AIR-BALANCE Package with "AMG#63", a unique fragrance has been developed for an AMG vehicle. It is an appealing, sporty scent to match the spirit of the performance sports car brand.
The new AMG GT 4-Door Coupé can also be fitted with the ENERGIZING comfort control for improved driver fitness. This system networks different vehicle functions such as the air conditioning system, seat controls, massage functions, seat and steering wheel heating as well as the ambient lighting, in order to relax or energise the driver and passengers in a targeted manner with predefined programs.
For the ultimate audio pleasure, the optional Burmester® High-End 3D Surround Sound system is available. 23 speakers and 1450-watt system output recreate the feeling of being in a concert hall or at a live festival, as the customer wishes. 3D speakers in the roof liner create a wide-ranging three-dimensional sound which extends beyond the vehicle's own contours. Among the further highlights are the High-End ring radiator tweeters and AMG's own specific subwoofer which, with its external connection, guarantees excellent bass performance. With VIP settings, individual seats can be selected and the sound staging optimised. As part of the high-grade personalisation of the sound experience, there are also style presets such as "Live" or "Easy Listening".
High sound and vibration comfort as well as fine-tuned aeroacoustics
The developers of the new Mercedes-AMG GT 4-Door Coupé placed special consideration on the great noise and vibration comfort of the interior, which makes a great contribution to the performance-enhancing comfort of the vehicle. Especially on long journeys, customers recognise this as an important characteristic of quality. Vibrations caused by the drivetrain, the road and the wheels – just like wind noise – are kept out of the interior as best as possible. To do this, the developers optimally tuned the rigidity of the body and the suspension. AMG speed-sensitive power steering minimises steering and road noises, while the dynamic transfer behaviour of the individual components in the axle structure and steering as well as the decoupling abilities of the suspension mounts were also improved.
The low level of wind noise goes hand-in-hand with the first-class aerodynamic values, and the proven noise insulation concept has also been further fine-tuned. The seals around the doors and windows shield wind noise, while the exterior mirrors and A pillars are fined- tuned to one another in such a way that unavoidable noises caused by air flow around them are kept to a minimum. Optimisations to the main floor keep low-frequency noises down.
