What is the Mercedes-AMG GLS 63?
The Mercedes-AMG GLS 63 is the pinnacle of performance within the Mercedes-Benz GLS lineup. It’s a full-size, three-row luxury SUV that has been meticulously engineered by AMG, Mercedes-Benz’s in-house performance division. This isn’t just a GLS with a bigger engine; it’s a complete transformation. AMG takes the already luxurious and spacious GLS and imbues it with the heart and soul of a supercar, delivering breathtaking acceleration, dynamic handling, and an exhilarating driving experience without compromising its family-friendly practicality. It’s the ultimate expression of power, luxury, and capability in an SUV form.
Engine and Performance: The Heart of the Beast
At the core of the Mercedes-AMG GLS 63’s “ultimate power” lies its formidable engine. AMG doesn’t just tune engines; they craft them to deliver an unparalleled experience.
Engine Details
The GLS 63 is powered by a handcrafted AMG 4.0-liter V8 Biturbo engine. This isn’t just any V8; it features advanced technologies like twin-scroll turbochargers strategically placed within the engine’s V-shape. This design reduces exhaust gas travel time, enabling quicker turbo spool-up and a more immediate throttle response – something you can feel with every press of the pedal.
Engine Code: M177
Displacement: 4.0 liters (3,982 cc)
Configuration: V8
Aspiration: Twin-turbocharged (Biturbo)
Induction: Direct injection with spray-guided combustion
Power and Torque Output
The numbers speak for themselves. The AMG GLS 63 is engineered to produce staggering figures that push the boundaries of what’s expected from an SUV of its size.
Horsepower: Up to 603 hp (450 kW) at 5,750-6,500 rpm
Torque: Up to 627 lb-ft (850 Nm) at 2,500–4,500 rpm
This explosive combination of horsepower and torque allows the GLS 63 to deliver relentless acceleration and effortless overtaking power.
AMG Performance 4MATIC+ All-Wheel Drive
Power is only useful if it can be effectively put to the ground. The AMG GLS 63 comes standard with AMG Performance 4MATIC+ all-wheel drive. This intelligent system variably distributes power between the front and rear axles. In its most dynamic modes, it can even send a significant portion of torque to the rear, mimicking the feel of a rear-wheel-drive vehicle for enhanced agility and a more engaging driving experience. This system is crucial for managing the V8’s immense power while maintaining stability and traction in various driving conditions. For excellent insights into modern all-wheel-drive systems, consider resources from organizations like the SAE International (Society of Automotive Engineers).
EQ Boost Mild Hybrid System
A key innovation in the latest generation GLS 63 is the integrated starter generator (ISG) and a 48-volt mild-hybrid system. This system performs several functions:
Power Boost: Provides an additional 21 hp and 184 lb-ft of torque for short bursts, enhancing acceleration and responsiveness, especially from a standstill.
Energy Recuperation: Captures kinetic energy during deceleration and braking, storing it in the battery to power the vehicle’s electronics and assist the engine.
Smooth Start-Stop: Allows for seamless engine restarts and smoother operation of the ECO start/stop function.
Reduced Emissions and Fuel Consumption: Contributes to overall efficiency improvements.
This integration of hybrid technology showcases AMG’s commitment to blending performance with a degree of environmental consciousness.
Transmission and Drivetrain
The engine’s power is managed by a highly capable transmission system designed to handle the V8’s output and deliver rapid, smooth shifts.
AMG SPEEDSHIFT TCT 9-Speed Transmission
The GLS 63 is equipped with an AMG SPEEDSHIFT TCT (Torque-Clutch Transmission) 9-speed automatic transmission. This transmission is specifically tuned by AMG to provide characteristics that complement its performance focus:
Direct and Agile Shifting: Offers extremely fast and precise gear changes, minimizing power interruption.
Double-Clutching Function: Automatically performs a rev-matched downshift when braking, making downshifts smoother and more engaging.
Multiple Shift Modes: Drivers can select from various modes (e.g., Comfort, Sport, Sport+) which alter shift speed, rev-matching intensity, and overall transmission behavior to suit the driving situation and driver preference.
“M” Mode: A dedicated manual mode allows drivers to take full control of gear selection via the steering wheel paddle shifters for maximum engagement.
The TCT gearbox uses a wet multi-disc clutch instead of a torque converter in some AMG applications for lighter weight and faster response. However, in the GLS 63, it utilizes a torque converter optimized for AMG requirements, balancing smooth take-off with quick engagement.
AMG DYNAMIC SELECT
Complementing the transmission are the AMG DYNAMIC SELECT drive programs. These modes not only adjust the transmission shift points and engine mapping but also influence the adaptive dampers and steering feel. Modes typically include:
Slippery: Optimized for low-grip conditions.
Comfort: Prioritizes smooth ride and relaxed driving.
Sport: Emphasizes sporty driving with quicker responses and firmer damping.
Sport+: The most aggressive setting, delivering maximum performance with rapid shifts and stiffest suspension.
Individual: Allows the driver to customize settings for various parameters.
The synergy between the engine, all-wheel drive, and transmission, all orchestrated by AMG DYNAMIC SELECT, is what truly unlocks the “ultimate power” experience.
Chassis and Suspension: Controlled Power
Handling a powerful SUV of this size requires a sophisticated chassis and suspension system. AMG has engineered the GLS 63 to be surprisingly agile for its segment.
AMG ACTIVE RIDE CONTROL AIRMATIC Suspension
The GLS 63 features an AMG-tuned version of the AIRMATIC air suspension system. This adaptive system constantly monitors driving conditions and adjusts damping forces at each wheel in real-time.
Adaptive Damping: Selectable modes (Comfort, Sport, Sport+) allow drivers to tailor the suspension’s firmness.
Self-Leveling: The suspension automatically adjusts to maintain a consistent ride height, even when the vehicle is heavily loaded.
Increased Roll Stabilization: AMG has implemented an active roll stabilization system, often referred to as a “dynamic” or “active” anti-roll bar system. This electromotive system counteracts body roll during cornering, keeping the SUV remarkably flat and composed. This is a critical component that allows such a large vehicle to handle with unexpected athleticism.
Steering System
The electromechanical speed-sensitive power steering is specifically tuned by AMG. It offers:
Variable Ratio: Becomes quicker at higher speeds for better stability and slower at lower speeds for easier maneuvering.
AMG Tuning: Provides precise feedback and a direct connection to the road, further enhancing the sporty driving feel.
Braking System
Such immense power necessitates an equally robust braking system. The GLS 63 is equipped with large, internally ventilated and perforated brake discs, often with silver or red AMG brake calipers.
Front: Typically 410mm discs with 6-piston fixed calipers.
Rear: Typically 370mm discs with single-piston floating calipers.
This setup provides exceptional stopping power and fade resistance, crucial for maintaining control under demanding driving conditions.
Dimensions and Weight
Understanding the physical scale of the Mercedes-AMG GLS 63 is important when considering its performance. As a full-size luxury SUV, it is substantial.
General Specifications Table:
| Feature | Specification |
