2024 Mercedes-AMG GT 63 4MATIC+ - Images, Specifications and Information

At market launch, the new AMG GT Coupé will be launched with two performance levels of the AMG 4.0‑litre V8 biturbo engine. The engines are assembled entirely by hand at the company's site in Affalterbach according to the "One Man, One Engine" principle. In the top model GT 63 4MATIC+ , the engine delivers 430 kW (585 hp) and provides a maximum torque of 800 Nm over a wide engine speed range from 2,500 to 4,500 rpm. Accelerating from 0 to 100 km/h takes just 3.2 seconds, and the top speed is 315 km/h. In the GT 55 4MATIC+ (combined fuel consumption 14.1 l/100 km, combined CO2 emissions 319 g/km), the V8 unit develops an output of 350 kW (476 hp) and a maximum torque of 700 Nm. The sprint from zero to 100 km/h takes 3.9 seconds, and the top speed is 295 km/h.

For use in the AMG GT Coupé, the engine received a new oil pan, repositioned intercooler, and active crankcase ventilation. The inlet and outlet ports have been optimised for more effective gas exchange and the exhaust gas routing for the catalytic converter box and Otto particle filter has been enlarged. The developers achieved the additional output of the AMG GT 63 4MATIC+ Coupé primarily through higher boost pressure and greater air throughput as well as modified engine software. All in all, the eight-cylinder impresses with its extraordinary power development with powerful boost in all engine speed ranges, combined with the highest possible efficiency for low consumption and emission values.

The engine is assembled entirely by hand. In the AMG engine factory at the Affalterbach site, the “One Man, One Engine” principle is linked to Industry 4.0 production methods. This is designed according to modern knowledge of ergonomics, the flow of goods, quality assurance, sustainability, and efficiency. Smart production is characterised by maximum flexibility, is transparent and highly efficient. In doing so, it secures and increases the quality of the engines and the production processes with digital technologies.

The AMG SPEEDSHIFT MCT 9G transmission combines an emotional shift experience with extremely short shift times and is specially tailored to the requirements of the new AMG GT Coupé. A wet starting clutch replaces the torque converter. It reduces the weight and, thanks to its lower mass inertia, optimises the response to commands from the accelerator pedal, especially when sprinting and changing loads.

The two V8 models are equipped as standard with the fully variable AMG Performance 4MATIC+ all‑wheel drive. The intelligent system combines the advantages of different drive concepts: The fully variable torque distribution on the front and rear axle not only ensures optimum traction at the physical limit. The driver can also rely on a high level of driving stability and driving safety under all conditions: on dry roads as well as on wet or snowy roads. The transition from rear to all-wheel drive and vice versa takes place continuously, based on a sophisticated matrix that integrates the intelligent control into the overall vehicle system architecture.

An electromechanically controlled clutch variably connects the constantly driven rear axle with the front axle. The best possible torque distribution is continuously calculated depending on the driving situation and the driver's wishes. The new coupé can be driven in a continuously variable manner from traction-oriented all-wheel drive with 50:50 power distribution to the front and rear axles to pure rear-wheel drive. In addition to traction and lateral dynamics, the all-wheel drive also improves longitudinal dynamics for even more powerful acceleration.

The new AMG GT Coupé offers a multi-link front axle with five links arranged entirely within the wheel rim. The wheel control and wheel suspension elements, which are independent of one another, enable high lateral acceleration with minimal drive influences on the steering system. A five-link space construction also guides the wheels on the rear axle.

To reduce the unsprung masses, all suspension links, steering knuckles and wheel carriers on the front and rear axles of the new AMG GT Coupé are made of forged aluminium. The multi-link concept guides each wheel with minimal elastic movements. The high camber and toe rigidity not only enables high cornering speeds, but also gives the driver optimal contact with the road in the high cornering limit area. This is reflected in excellent lateral dynamics and driving stability at high speeds, as well as in the good-natured response to external influences such as crosswinds, bumps in the road or jumps in the coefficient of friction. A particularly direct connection of the shock absorber to the rear wheel carrier reduces vibrations and undesirable wheel load fluctuations. The wheel control and wheel suspension elements, which are independent of each other, enable high lateral acceleration with minimal drive influences on the steering system - also a comfort feature.

Added to this is the AMG ACTIVE RIDE CONTROL suspension with roll stabilisation. Active hydraulic elements replace the conventional mechanical torsion bar anti-roll bars and compensate for rolling movements in the new AMG GT Coupé in fractions of a second. The adaptive shock absorbers also have two hydraulic connections. One is on the compression side of the damper and the other is on the tension side. The damper chambers on all four wheels and the lines are connected directly via the control valves of the adaptive dampers.

The intelligent hydraulic interconnection of the four spring struts and the pressure regulation of the pump and switching valves allow a very wide roll spring rate with reduced rolling movements at the same time. Figuratively speaking: every torsion bar from zero to stiff can be displayed automatically. In everyday life, this increases comfort because even unevenness that occurs on one side is individually compensated. When cornering dynamically, the hydraulics also actively reduce fall loss. Thanks to the resulting high camber rigidity, the coupé steers very precisely.

When driving straight ahead, the system is opened completely depending on the driving programme and driving situation. The system compensates for individual obstacles that would otherwise lead to rolling movements. Drivers and passengers experience a significantly more comfortable driving experience. The reduced body roll when cornering contributes equally to comfort and driving dynamics. The characteristics of the driving behaviour in the individual driving programmes can be spread more between comfort and sport.

The basic principle of the chassis is that the compression and tension sides of the vehicle's individual dampers are interconnected. The compression stage of the front left damper is connected to the rebound stage of the front right damper via a hydraulic line. There is also a connection to the pressure side of the rear left damper and the rebound stage of the rear right damper via a line across the vehicle. Analogously, the other sides of the damper chambers are connected to one another via a second circuit. The simplified course of the hydraulic lines results in the shape of an "H".

In addition to the interconnection of the dampers, other components that are important for the function are used in the system. The tension and pressure sides of the dampers are directly connected to each other via an electrically controllable 2/2‑way valve, known as the comfort valve. A pressure accumulator is also attached to each of the damper pressure sides. Both circuits are also connected to a central pump. It ensures that the hydraulic system pressure can be adjusted in both circuits. The connection between the pump and the circuits is made via 2/2‑way valves. Pressure sensors are integrated behind the valves to monitor the system pressure in the respective lines. The system pressure can be freely selected and thus also the size of the generated anti-roll control. The following applies: the higher the system pressure, the greater the expected roll stiffness.

The system works very efficiently because it uses the vehicle's existing kinetic energy to positively influence roll behaviour. The hydraulics of the AMG ACTIVE RIDE CONTROL suspension also feed the optional lift system for the front axle. If necessary, the front end can be raised by 30 millimetres, making it easier, for example, to drive into underground car parks or over speed bumps. The lift system is operated via the multimedia central display or via the AMG steering wheel buttons. The corresponding menu opens after you press the vehicle symbol on the control bar. Among other things, positions can be saved using GPS technology so that the front end of the vehicle is automatically raised when the corresponding points are passed again.

The new AMG GT Coupé has an electronically controlled rear axle locking differential as standard, which ensures excellent traction and maximum driving safety in all driving conditions. Not only is the traction of the drive wheels on the rear axle further improved, the cornering speeds in the limit area also increase. In addition, driving stability is optimised when changing lanes at high speed. The system works with a variable locking effect in traction and overrun mode and is perfectly matched to the different driving conditions and road surface friction values.

The new AMG GT Coupé is also equipped with active rear-axle steering (HAL) as standard. Depending on the speed, the rear wheels steer in either the opposite direction (up to 100 km/h) or in the same direction (faster than 100 km/h) as the front wheels. The system thus enables agile and stable driving behaviour in equal measure - characteristics that conflict with one another without rear-axle steering. Further advantages are the easier vehicle controllability in the limit area as well as less steering effort because the translation of the front wheel steering is more direct.

The AMG high-performance compound brake system guarantees excellent deceleration values and precise metering. It impresses with short braking distances, sensitive response behaviour and high stability - even under extreme loads. The composite brake discs are particularly light: Driving dynamics and steering behaviour benefit from the reduced unsprung masses. Brake disc (made of cast steel) and brake pot (made of aluminium) are now connected with special pins and no longer with screws as before. This construction saves space, which is used for even better brake cooling. The directional perforation is also new: In addition to the weight savings and better heat dissipation, this solution scores with a faster response in the wet and better cleaning of the pads after braking.

The six AMG DYNAMIC SELECT drive programmes "Slippery", "Comfort", "Sport", "Sport +", "Individual" and "RACE" enable a wide range of vehicle characteristics from comfortable to dynamic. Each programme offers an individual driving experience, precisely tailored to different driving conditions. As a feature within the AMG DYNAMIC SELECT drive programmes, the AMG GT models also have AMG DYNAMICS. This integrated driving dynamics control expands the stabilising functions of ESP® with agile interventions in the all-wheel drive control, the steering characteristic and in additional ESP® functions. When cornering dynamically, for example, a brief application of the brakes on the rear wheel on the inside of the corner causes a defined yawing moment around the vertical axis for spontaneous and precise steering. The spectrum ranges from extremely stable to highly dynamic.

AMG TRACK PACE is on board as standard. The software is part of the MBUX infotainment system and records more than 80 pieces of vehicle-specific data (e.g., speed, acceleration, steering angle, brake pedal actuation) ten times per second while driving over a defined route. 40 parameters can be displayed live in the "Telemetry" screen, up to four of them at the same time.

In addition, lap and sector times are displayed on the multimedia display, head-up display and in the instrument cluster, as well as additional training and analysis tools. The navigation in the head-up display shows cornering angles and braking points, helping you to find the best line. The MBUX augmented reality function also enables the line from a saved recording to be shown on the multimedia display. In this way, the driver can improve his driving style like with a virtual instructor. Acceleration and deceleration values can also be measured and saved.

The equipment details and numerous options offer a wide range of customisation for the most diverse customer requests - from sporty and dynamic to luxuriously elegant. This includes eleven paint colours and eight new wheel designs. There are five exterior design packages to choose from to sharpen the look further in the direction of elegance or dynamism. The AMG GT 55 4MATIC+ and AMG GT 63 4MATIC+ roll on 20‑inch AMG multi‑spoke light‑alloy wheels as standard. Alternatives in 21‑inch format are also available.

With the help of numerous sensors, cameras and radar, driver assistance systems monitor the traffic and the surroundings of the new coupé. If necessary, the intelligent helpers can intervene at lightning speed. Drivers are supported by numerous new or expanded systems - in everyday situations, for example by distance control, steering and lane changes. In the event of danger, the systems help to react appropriately to an imminent collision. The functioning of the systems is visualised by a new display concept in the instrument cluster.

The assistance display in the instrument cluster clearly and transparently shows how the driver assistance systems work in a full-screen view. The driver recognises the car, lanes, lane markings and other road users such as cars, trucks, and two-wheelers in a spatially abstract manner. The system status and functionality of the assistants are visualised based on this representation of the environment. The new animated assistance display is based on a 3D scene generated in real time. This high-quality and dynamic representation makes the functionality of the driver assistance systems transparent in an augmented reality driving experience.

The MBUX (Mercedes-Benz User Experience) infotainment system makes it possible to use many digital services from Mercedes me connect. The advantages are the smartphone integration of Apple CarPlay and Android Auto, the hands-free system via Bluetooth connection and digital radio (DAB and DAB+). In connection with MBUX, customers have access to connectivity services such as live traffic information. With Mercedes me connect, the new AMG GT Coupé becomes more intelligent overall: additional functions can be used before and after the journey or while on the move. All you need to do is link the coupé to a Mercedes me account in the Mercedes me portal and accept the terms of use. Thanks to navigation with live traffic information and Car‑to‑X communication, customers drive with real-time traffic data. You can avoid traffic jams efficiently and save valuable time. Networked vehicles use car‑to‑x communication to exchange information about traffic events.
