The Mercedes-AMG GT 63 S represents the pinnacle of automotive engineering where uncompromising luxury converges with devastating performance capabilities. This four-door coupe transcends conventional boundaries, delivering 630 horsepower through its meticulously crafted 4.0-litre V8 biturbo engine whilst maintaining the refinement expected from the three-pointed star. The GT 63 S doesn’t merely compete in the luxury performance segment—it redefines expectations with its sophisticated blend of track-focused dynamics and premium comfort appointments.
What distinguishes the GT 63 S from its contemporaries is its ability to transform from a civilised grand tourer into a track-ready weapon at the touch of a button. Mercedes-AMG has achieved this remarkable duality through advanced engineering solutions that span every aspect of the vehicle’s construction, from its lightweight carbon fibre body panels to its intelligent all-wheel-drive system.
AMG 4.0-litre V8 biturbo engine architecture and performance metrics
The heart of the Mercedes-AMG GT 63 S lies in its hand-built 4.0-litre V8 biturbo engine, designated internally as the M177. This powerplant represents decades of motorsport heritage and engineering excellence, delivering exceptional performance figures that place it amongst the most potent production engines available today. The engine produces 630 horsepower at 5,500-6,500 rpm and generates an impressive 900 Nm of torque from as low as 2,500 rpm, ensuring explosive acceleration across the entire rev range.
M177 engine block construction and cylinder head design
The M177 engine features a closed-deck aluminium crankcase construction that provides exceptional structural rigidity whilst maintaining relatively low weight. The cylinder heads incorporate advanced port injection technology alongside direct fuel injection, creating optimal combustion conditions under varying load scenarios. This dual-injection system ensures precise fuel delivery whilst reducing particulate emissions, demonstrating Mercedes-AMG’s commitment to both performance and environmental responsibility.
Twin-scroll turbocharger configuration and boost pressure management
Two twin-scroll turbochargers positioned within the engine’s V-configuration minimise turbo lag whilst maximising power delivery. The hot-inside-V layout reduces the distance between exhaust ports and turbochargers, ensuring rapid spool-up and immediate throttle response. Advanced wastegate control manages boost pressure dynamically, allowing the engine to deliver consistent power output across diverse driving conditions whilst protecting internal components from excessive stress.
630 horsepower output and 900 nm torque delivery characteristics
The GT 63 S’s power delivery characteristics showcase the sophisticated calibration work undertaken by AMG engineers. Peak torque arrives early in the rev range and maintains a broad plateau, ensuring strong acceleration regardless of engine speed. This torque characteristic makes the vehicle exceptionally responsive in real-world driving scenarios, whether accelerating from standstill or overtaking at motorway speeds. The engine’s ability to sustain high power output during extended track sessions demonstrates its robust internal construction and advanced cooling systems.
AMG SPEEDSHIFT DCT 9G transmission integration
The nine-speed AMG SPEEDSHIFT DCT transmission represents a masterclass in automotive transmission technology. Unlike conventional dual-clutch systems, this unit incorporates a wet-clutch design that provides smoother engagement during low-speed manoeuvres whilst maintaining rapid shift speeds under performance conditions. The transmission features multiple operating modes, from comfort-oriented settings for daily driving to race-calibrated programs that prioritise lightning-fast gear changes and aggressive downshift strategies.
Dynamic performance systems and advanced drivetrain technology
The Mercedes-AMG GT 63 S employs sophisticated drivetrain technology to translate its substantial power output into usable performance. The vehicle’s dynamic systems work in harmony to provide exceptional traction, stability, and driver engagement across varying road conditions and driving scenarios.
AMG performance 4MATIC+ All-Wheel drive distribution
The AMG Performance 4MATIC+ system represents an evolution of traditional all-wheel-drive technology, incorporating variable torque distribution between front and rear axles. Under normal
driving, the system favours a rear-biased torque split to preserve the classic AMG feel, only sending additional power to the front axle when sensors detect slip or when you select more aggressive drive modes. In extreme cases, the system can route almost all available torque to the rear wheels, creating a near-pure rear-wheel-drive sensation for drivers who enjoy a more playful, dynamic character. The result is a luxury performance car that feels composed on wet, uneven roads yet alive and adjustable when you push harder on dry tarmac.
AMG DYNAMIC SELECT drive modes and suspension calibration
AMG DYNAMIC SELECT is the central interface that allows you to tailor the Mercedes-AMG GT 63 S to your driving mood. Through simple controls on the centre console or the AMG steering wheel, you can choose from Comfort, Sport, Sport+, Race, Individual, and in some markets, a Slippery mode. Each mode recalibrates engine mapping, throttle sensitivity, transmission shift strategy, steering weight, and stability control thresholds to create distinct driving personalities within the same vehicle.
In Comfort mode, the GT 63 S settles into a refined, almost limousine-like character with early upshifts and a subdued exhaust note, ideal for urban use or long-distance cruising. Switch to Sport or Sport+ and the car sharpens its responses, holding gears longer and allowing more exhaust overrun for a more emotional soundtrack. The Race program further reduces electronic intervention and primes every system for circuit use, while Individual mode lets you mix and match settings, combining for example a comfort-oriented suspension with the aggressive throttle map of Sport+ if that best fits your driving style.
AMG RIDE CONTROL+ air suspension with adaptive damping
The AMG RIDE CONTROL+ air suspension is crucial to the GT 63 S’s ability to combine everyday usability with track-ready dynamics. Using multi-chamber air springs and continuously adjustable damping, the system can vary spring rates and damping characteristics in milliseconds, based on road surface, driving style, and selected drive mode. Think of it as having multiple sets of bespoke suspension setups stored in the car’s memory, instantly available whenever you need them.
Under gentle driving, the suspension softens, filtering out bumps and surface imperfections, which is particularly beneficial on long motorway journeys. As lateral acceleration and steering inputs increase, the system firms up the damping, reducing body roll and pitch to keep the car flat and composed through aggressive cornering. The air suspension can also adjust ride height, lowering the car at speed to enhance aerodynamics and stability, while raising it slightly over speed bumps or steep driveways to protect the front splitter.
Electronic rear axle locking differential operation
To help the Mercedes-AMG GT 63 S put its 900 Nm of torque to the ground efficiently, AMG fits an electronically controlled rear axle locking differential. This component continuously varies the locking effect between the rear wheels, based on input from wheel-speed sensors, yaw rate, steering angle, and throttle position. In simple terms, it ensures that the wheel with the most grip gets the most power, improving traction during hard acceleration out of tight corners.
On a twisty road or circuit, the differential also reduces inside-wheel spin, allowing you to accelerate earlier and more confidently when exiting a bend. At the same time, it supports the car’s dynamic stability systems, making transitions between understeer and oversteer more predictable and controllable. For the driver, the benefit is a sensation of the rear end powering you out of the corner, rather than being dragged along—a subtle but vital difference that enthusiasts will appreciate.
Aerodynamic engineering and carbon fibre body construction
The aerodynamic package of the Mercedes-AMG GT 63 S is far more advanced than its elegant silhouette might suggest. Every contour, air intake, and outlet is designed to manage airflow, reduce drag, and increase downforce where needed. Active aerodynamics, including a multi-stage rear spoiler and adjustable air flaps in the front apron, automatically adapt based on speed, lateral acceleration, and selected drive mode, balancing stability and efficiency in real time.
Extensive use of carbon fibre reinforced plastic (CFRP) in key body components—such as the roof, rear spoiler, and various underbody elements—helps reduce weight while maintaining structural rigidity. This not only benefits straight-line performance and fuel efficiency but also lowers the car’s centre of gravity, improving turn-in response and reducing body roll. For buyers who regularly visit track days, optional carbon fibre exterior packages further reduce mass and enhance cooling by optimising airflow to the brakes and engine bay.
AMG track pace telemetry and performance monitoring systems
For drivers who want to explore the full potential of the Mercedes-AMG GT 63 S on a circuit, the integrated AMG TRACK PACE system is an invaluable tool. Functioning as a virtual race engineer, it records more than 80 vehicle parameters in real time, including lap times, sector splits, steering angles, throttle positions, and lateral/longitudinal acceleration values. You can think of it as having professional telemetry software built directly into your infotainment system.
Within the MBUX interface, AMG TRACK PACE provides clear visualisations of your performance, highlighting areas where you can brake later, accelerate earlier, or refine your racing line. Pre-loaded tracks—such as the Nürburgring Nordschleife and Spa-Francorchamps—are available in many markets, and you can also define your own circuits using GPS data. Over time, this allows you to review your laps, compare sessions, and systematically improve your driving technique, whether you are a seasoned track-day regular or just starting to explore high-performance driving.
Luxury interior craftsmanship and nappa leather appointments
Step inside the Mercedes-AMG GT 63 S and the emphasis shifts from raw power to refined luxury. The cabin showcases meticulous craftsmanship, with extensive use of Nappa leather, metal switchgear, and optional carbon fibre or open-pore wood trim. Every touchpoint, from the door panels to the centre console, is designed to feel solid, premium, and purpose-built for a high-performance grand tourer.
Despite its track-capable engineering, the GT 63 S never forgets its role as a daily-use luxury coupe. Ambient lighting with multiple colour schemes, four-zone climate control, and generous seating space in the rear ensure that passengers enjoy the same level of comfort as the driver. For many owners, this balance—where you can commute in serenity during the week and unleash the car’s potential on a Sunday morning drive—is what makes the Mercedes-AMG GT 63 S such a compelling proposition.
AMG performance seats with memory function
The AMG Performance seats play a central role in connecting the driver to the car’s dynamic capabilities. Designed with pronounced side bolsters and integrated headrests, they provide strong lateral support during spirited driving while still remaining comfortable on long journeys. Multi-contour adjustments, including lumbar support and seat cushion angle, allow you to fine-tune your seating position with impressive precision.
Integrated memory functions store multiple driver profiles, including seat, steering wheel, and mirror settings—ideal if more than one person regularly drives the car. Optional seat heating and ventilation broaden the usability of the GT 63 S across different climates, ensuring year-round comfort. If you spend significant time behind the wheel, this level of ergonomics is more than a luxury; it actively helps reduce fatigue and maintain concentration, particularly on long high-speed trips.
MBUX infotainment system with AMG-Specific display modes
The MBUX infotainment system in the Mercedes-AMG GT 63 S combines cutting-edge connectivity with AMG-specific graphics and functions. Two high-resolution 12.3-inch displays—one for the instrument cluster and one for the central multimedia screen—create a widescreen cockpit that is both visually striking and highly functional. You can choose between several instrument layouts, including Sport and Supersport modes, which emphasise performance data such as boost pressure, G-forces, and gear selection.
Voice control with natural language understanding (“Hey Mercedes”) enables you to manage navigation, climate settings, and media without taking your hands off the AMG steering wheel. Smartphone integration via Apple CarPlay and Android Auto, along with multiple USB-C ports, ensures that your digital life connects seamlessly to the car. For performance enthusiasts, the AMG menu within MBUX displays detailed information about engine output, transmission temperatures, and suspension status—vital data if you are pushing the car on a mountain pass or circuit.
Burmester 3D surround sound system integration
For many owners, a luxury performance vehicle must thrill not only through its exhaust note but also through its audio system. The optional Burmester 3D Surround Sound system in the GT 63 S delivers an audiophile-grade listening experience, using high-performance speakers strategically positioned throughout the cabin. An external multi-channel amplifier and advanced digital signal processing create a three-dimensional soundstage that can be tailored to your preferences.
Whether you are listening to classical music during a late-night drive or high-energy playlists on the way to a track day, the system maintains clarity, depth, and impressive dynamic range. Sound optimisation modes allow you to focus audio either on the front seats or evenly throughout the interior, depending on how many passengers you have on board. Combined with the car’s excellent noise insulation, the Burmester system transforms the cabin into a rolling concert hall when you are not letting the V8 provide the soundtrack.
Carbon fibre trim elements and AMG steering wheel design
The visual and tactile centrepiece of the driver’s environment is the AMG Performance steering wheel. Typically trimmed in Nappa leather, DINAMICA microfibre, or a combination of both, it features a thick rim and sculpted thumb rests to provide a secure grip during fast driving. Integrated AMG steering wheel buttons let you quickly alter drive modes, suspension stiffness, and exhaust sound, allowing on-the-fly adjustments without diverting your attention from the road.
Carbon fibre trim elements across the dashboard, centre console, and door panels underscore the car’s motorsport DNA while keeping overall weight in check. These components are not merely decorative; they offer a subtle reminder that the GT 63 S is engineered with the same materials and philosophy as Mercedes-AMG’s racing cars. Together with the high-resolution displays and ambient lighting, the result is a cockpit that feels as much like a high-end flight deck as a traditional luxury car interior.
Track-focused variants and circuit performance capabilities
While every Mercedes-AMG GT 63 S is inherently capable on a circuit, AMG also offers configurations and packages that push its track performance even further. These may include enhanced aerodynamic components, lighter forged wheels, and dedicated track tyres, all designed to shave precious seconds off lap times. If you are the kind of driver who enjoys analysing telemetry and chasing personal bests, these track-focused variants provide a level of capability that rivals purpose-built sports cars.
Despite its four-door, four-seat layout, the GT 63 S’s chassis tuning, braking hardware, and thermal management systems are engineered to withstand repeated high-speed laps without significant performance fade. That means you can spend an entire track day exploring the limits of grip, braking, and acceleration, then drive home in comfort without worrying about mechanical fatigue. For owners who want one car that can genuinely “do it all”, this breadth of ability is a major advantage.
Nürburgring lap time achievements and track records
The Nürburgring Nordschleife has long been the benchmark by which manufacturers measure the ultimate capability of their performance cars, and the Mercedes-AMG GT 63 S has made a strong showing there. In previous tests, the GT 63 S 4MATIC+ has posted lap times that place it among the fastest four-door production cars ever to tackle the Green Hell. These achievements are not marketing gimmicks; they are the result of painstaking development work carried out by AMG engineers and professional test drivers.
Why does this matter to you as a prospective owner? Because a car capable of maintaining composure and speed on the Nordschleife—arguably one of the most demanding circuits in the world—will feel effortlessly stable and secure on public roads. Long, high-speed sweepers, quick direction changes, and heavy braking zones on the motorway or autobahn are precisely the kind of scenarios the GT 63 S has been tuned to master. The Nürburgring results, therefore, act as a real-world validation of its chassis balance, aero efficiency, and drivetrain durability.
Michelin pilot sport cup 2 tyre compound selection
Tyres are the only contact point between the Mercedes-AMG GT 63 S and the road, so AMG works closely with premium manufacturers such as Michelin to develop bespoke compounds. For track-oriented specifications, the car can be equipped with Michelin Pilot Sport Cup 2 tyres—ultra-high-performance rubber designed to deliver exceptional grip and consistency during hard circuit use. Their tread compound and construction allow for high cornering forces and remarkable braking stability, particularly once warmed to optimal operating temperature.
On a dry track, these tyres can transform the way the car feels, offering sharper turn-in, higher mid-corner speeds, and shorter stopping distances. However, as with any track-focused tyre, there are trade-offs: in colder temperatures or heavy rain, a more road-biased tyre like the Pilot Sport 4S may offer better everyday security. As an owner, it can be wise to maintain two sets of wheels and tyres—one for daily driving and one for track events—if you plan to exploit the GT 63 S’s full circuit potential.
AMG ceramic High-Performance brake system specifications
To repeatedly slow a car with 630 horsepower from high speeds, you need a braking system that is both powerful and resilient. The optional AMG ceramic high-performance brakes on the GT 63 S feature large, ventilated and perforated discs made from a carbon-ceramic composite material. Paired with multi-piston calipers—often finished in a distinctive bronze or gold colour—these brakes deliver immense stopping power with excellent fade resistance, even after numerous high-speed laps.
Compared to traditional steel brakes, ceramic discs are lighter and more resistant to heat, which benefits both handling and long-term durability. Pedal feel remains consistent, giving you the confidence to brake later and harder as you become more familiar with the car’s behaviour on track. While the ceramic system commands a premium, it is a worthwhile investment if you intend to use the Mercedes-AMG GT 63 S regularly in demanding driving environments where braking performance is paramount.
Competition with porsche 911 turbo S and BMW M8 competition
Any discussion of the Mercedes-AMG GT 63 S must consider its rivals in the high-performance luxury segment, particularly models like the Porsche 911 Turbo S and BMW M8 Competition. Each of these cars offers staggering acceleration, advanced chassis technology, and a lavish interior, but they take slightly different approaches. The Porsche 911 Turbo S is a benchmark for two-door sports car agility, while the BMW M8 Competition blends grand touring comfort with ferocious straight-line speed.
So where does the GT 63 S fit into this landscape? Its unique selling point is the combination of four-door practicality, a genuinely usable rear seat, and a large boot, without sacrificing the kind of performance you would expect from a dedicated sports coupe. In many ways, it feels like three cars in one: a luxury sedan, a long-distance GT, and a track-capable performance machine. For buyers who need everyday usability but refuse to compromise on driving excitement, that blend of attributes makes the Mercedes-AMG GT 63 S one of the most compelling choices in its class.
