The Mercedes-AMG GLS 63 4Matic+ arrives with 612 hp, a striking new look, and a fully reworked V8 engine. This seven-seater blends high performance with luxury, but its exclusivity comes at a price.
The Mercedes-AMG GLS 63 4Matic+ makes an immediate impression with its sheer size and presence. The latest update brings a redesigned front end, featuring new star-patterned headlights and a massive illuminated chrome grille that dominates the vehicle’s face. For those seeking a more assertive look, Mercedes now offers the Night II package, adding darker accents to the already imposing SUV.
Replacing the previous Monoblock wheels, the GLS 63 now rides on 23-inch alloys available in several designs, further emphasizing its XXL proportions. At over 5.2 meters long and more than two meters wide, the GLS 63 stands out even among luxury SUVs. The rear design is equally distinctive, with three star-shaped taillights on each side and a central chrome logo, creating a signature seven-star motif unique to this model.
Performance remains at the heart of the AMG identity. The GLS 63 retains its 4.0-liter V8 biturbo engine, now updated and dubbed the M 177 Evo. While the output stays at 612 hp and 850 Nm of torque, Mercedes-AMG has introduced significant technical changes, including a revised intake camshaft, upgraded injection system, and a new flat-plane crankshaft. These updates aim to future-proof the V8, ensuring both power and efficiency for years to come.
The drivetrain continues to feature the fully variable 4Matic+ all-wheel drive system and a nine-speed AMG Speedshift TCT 9G automatic transmission. A mild hybrid system adds an extra 23 hp and 205 Nm, supporting the V8 during acceleration. The result is a 0-100 km/h sprint in just 4.2 seconds and an electronically limited top speed of 280 km/h. Standard equipment includes active roll stabilization, an electronically controlled rear differential, and AMG Ride Control+ air suspension, offering six selectable driving modes for a tailored experience.
Inside, the GLS 63 sets itself apart with a triple 12.3-inch Superscreen display stretching across the dashboard. While the black bars between screens may divide opinion, the overall effect is modern and immersive. The cabin combines AMG’s signature sportiness with genuine luxury, and unlike most AMG models, the GLS 63 comes standard with a third row of seats, making it a true seven-seater. Buyers can also opt for individual seats in the second row, transforming the SUV into a six-seat configuration for added comfort.
For those comparing the Mercedes-AMG GLS 63 to other high-performance SUVs, it’s worth noting how the segment is evolving. Models like the BYD Atto 2 are pushing boundaries in range and everyday usability, as explored in this recent analysis of the electric SUV market. However, few rivals can match the GLS 63’s blend of power, space, and luxury for seven passengers.
In summary, the Mercedes-AMG GLS 63 4Matic+ remains a rare proposition: a full-size luxury SUV with supercar-level performance and genuine family practicality. The decision to retain and upgrade the V8 engine signals Mercedes-AMG’s commitment to traditional driving excitement, even as the industry shifts toward electrification. For buyers seeking uncompromising space, speed, and status, the GLS 63 stands virtually alone in its class.
Additional context: The GLS 63’s closest competitors include the BMW X7 M60i and the Audi SQ7, but neither offers the same combination of outright power and standard seven-seat layout. Pricing for the new GLS 63 is expected to reflect its exclusivity, positioning it at the top end of the luxury SUV market.
