The 2025 Mercedes-AMG GLS 63 stands in the rarefied air at the top of the luxury full-size SUV segment, blending immense power with a lavish cabin and advanced driving technology. As AMG’s answer to super-SUVs, the GLS 63 brings track-worthy output and handling to a seven-seater, while never compromising on comfort or prestige.
Overview
The GLS 63’s presence is unmistakable: broad stance, signature AMG grille, a sculpted hood, aggressive bumpers, and standard 21-inch (or optional 22- and 23-inch) AMG wheels. Chrome or gloss black details underline its luxury intentions, while quad exhaust outlets and subtle badging hint at the brutality under the hood.
Engine & Performance
At the heart of the GLS 63 lies a handcrafted 4.0-liter V8 biturbo engine with a 48V mild-hybrid system (EQ Boost), delivering a prodigious 603 HP and 850 NM of torque. This power is sent to all four wheels via AMG Performance 4MATIC+ all-wheel drive and a 9-speed AMG SPEEDSHIFT TCT automatic transmission.
Performance is remarkable for such a large SUV: 0 to 100 KM/H happens in as little as 4.2 seconds, with top speed electronically limited to 250 KM/H (some reports note a possible 280 KM/H with the AMG Driver’s package). The EQ Boost mild-hybrid system contributes momentary bursts of up to 21 HP and improved stop-start smoothness, while reducing emissions and turbo lag.
Chassis & Dynamics

The GLS 63 comes equipped with AMG Active Ride Control air suspension, actively adjusting damping and ride height in real time. Adaptive air suspension, rear-biased torque vectoring, and rear-axle steering provide agility and stability that defy its size. Massive AMG brakes, performance tires, and selectable drive modes transform it from serene boulevardier to apex-stalking bruiser at the press of a button.
Interior

Inside, the GLS 63 is every inch a flagship Benz: available in 6- or 7-seat layouts, appointed with diamond-stitched Nappa leather, open-pore wood or carbon trims, and the latest MBUX infotainment system via a massive dual-screen setup. The Burmester surround sound system, heated/cooled/massaging seats, multi-colour ambient lighting, wireless phone charging, panoramic sunroof, and four-zone climate control are all standard or available.
Innovative features include AMG-specific displays, augmented reality navigation, and an optional Executive Rear Seat package with individual captain’s chairs and extra amenities for the second row.
Safety & Technology
All models are loaded with Mercedes’ full suite of safety tech, including adaptive cruise, blind spot monitoring, lane keep assist, autonomous emergency braking, 360-degree camera, as well as attention and drowsiness alerts.
Space & Utility
The GLS 63 offers seating for seven (six with executive seating), sizable legroom in all rows, and up to 2,400 litres of total cargo capacity with seats folded. Towing capability stands at 3,300 KG, further highlighting its versatility.
Fuel Economy
The mild-hybrid system helps slightly, but this AMG is still a thirsty beast: real-world fuel consumption averages between 13 to 17 litres per 100 KM, putting it in line with segment rivals.
UAE Pricing
In the UAE, the 2025 Mercedes-AMG GLS 63 is priced from approximately AED 821,500 up to around AED 850,000, depending on spec and options. This base price places it directly against the BMW X7 M60i, Cadillac Escalade-V, and Range Rover.
