For families wanting supercar-level performance wrapped in Mercedes luxury, the 2026 GLS 63 stands in a class of its own.
A More Aggressive and Modern Exterior Design
Mercedes has updated the GLS 63 with new AMG-specific styling that highlights its athletic personality. The front fascia features a larger Panamericana grille, reshaped LED headlamps and a deeper bumper with bigger air inlets to improve cooling. The side profile showcases muscular lines, larger performance wheels and chrome accents, while the rear gets refreshed LED taillights and an AMG quad-exhaust system. The SUV looks both elegant and intimidating, embodying AMG’s performance-first identity.
Electrified V8 Power With 603 HP on Command
Under the hood, the 2026 AMG GLS 63 retains its handcrafted 4.0-liter twin-turbo V8 paired with EQ Boost mild-hybrid technology. The engine produces a stunning 603 horsepower, while the electric starter-generator adds extra torque during acceleration. AMG’s 9-speed transmission delivers lightning-fast shifts, and the 4MATIC+ all-wheel-drive system provides seamless traction, allowing the massive SUV to accelerate with sports-car intensity. Despite its size, the GLS 63 can sprint from 0 to 60 mph in under 4 seconds.
Improved Ride Dynamics and AMG Chassis Tuning
The 2026 model benefits from refined AMG Active Ride Control, adaptive air suspension and enhanced body-roll stabilization. These updates give the GLS 63 the rare ability to feel composed at high speeds while remaining buttery smooth around town. Steering response has been tightened for sharper handling, and upgraded brakes provide stronger stopping power. Even with its massive proportions, the GLS feels surprisingly agile and confident on corners.
Ultra-Luxury Cabin With New Tech Enhancements

Wireless Apple CarPlay, Android Auto, an enhanced navigation suite and customizable ambient lighting transform the cabin into a high-tech lounge. Optional Maybach-inspired features, including massage seating and dual rear entertainment screens, elevate the rear passenger experience to true luxury.
Advanced Safety and Driver Assistance Features
The GLS 63 includes Mercedes’ highest-tier safety suite, offering adaptive cruise assistance, lane-keeping support, 360-degree camera view, blind-spot monitoring and traffic jam assistance. AMG has tuned these systems to operate smoothly and predictably, allowing the SUV to maintain high safety performance without compromising its sporty character.
