Mercedes-Benz GLS AMG

Model Overview

The Mercedes-AMG GLS is a full-size high-performance luxury SUV developed by Mercedes-AMG based on the Mercedes-Benz GLS, standing as the flagship performance model with the largest footprint and highest seating capacity in the AMG stable. Built on the Mercedes-Benz MHA modular platform, it seamlessly integrates AMG's high-performance DNA with the seven-seater luxury space of the GLS. In June 2026, Mercedes-AMG unveiled the refreshed AMG GLS 63. As of June 2026, the 2026 AMG GLS 63 4MATIC+ is on sale in China with an official retail price of RM2,471,000. In the US market, base pricing starts at approximately USD 133,100, with the tested unit priced at USD 149,100. As the performance flagship of the GLS family, the AMG GLS 63 carries the market mission of setting the benchmark for combining uncompromised performance with practical versatility in the full-size luxury SUV segment.

Design Language

The new AMG GLS 63 takes a distinct exterior styling approach from the standard GLS—eschewing a fully blacked-out aesthetic in favour of an expansive chrome vertical-slat Panamericana grille and chrome front bumper accents, perfectly accentuating the commanding presence expected of a flagship performance SUV. The redesigned headlamps feature a fresh internal graphic with twin three-pointed star lighting elements, delivering unmistakable road presence when illuminated. Along the flanks, classic details such as chrome window surrounds and chrome door handles are retained, complemented by signature V8 BITURBO fender badging. At the rear, a full-width chrome trim strip bridges the tail lamps above a quad-exhaust layout, serving as key visual differentiators from the standard GLS. Rolling stock on the range-topping variant includes optional 23-inch AMG multi-spoke forged alloy wheels paired with red brake calipers. In terms of dimensions, the wheelbase spans 3,135 mm. Inside, the cabin is fitted with a chunky AMG-exclusive steering wheel integrated with dedicated AMG drive-mode rotary dials. Carbon-fibre trim panels, aluminium alloy accents, and red ambient lighting further enhance the cabin's sporty and opulent ambiance. The infotainment system also provides real-time performance telemetry, including torque distribution, G-force readouts, and engine operating parameters.

Powertrain Performance

The powertrain remains the defining highlight of the AMG GLS 63. The new model is powered by the M177 EVO 4.0-litre twin-turbo V8 engine, handcrafted under AMG's renowned "One Man, One Engine" philosophy at the Affalterbach plant. By adopting a revised flat-plane crankshaft, re-profiled intake camshafts, and an upgraded fuel injection system, the engine complies with the latest global emission standards while preserving its immense power output. It delivers a maximum output of 450 kW (612 PS / 603 hp) and 850 Nm of peak torque. Working in tandem with an ISG 2.0 integrated starter-generator and a 48V mild-hybrid system, it provides an additional 17 to 23 PS and 205 Nm of electrical boost. Power is sent to the wheels via an AMG SPEEDSHIFT TCT 9-speed automatic transmission. The official 0–100 km/h century sprint is completed in just 4.2 seconds, with top speed electronically capped at 280 km/h. The SUV also features a newly developed valve-controlled sports exhaust system that adapts its acoustic profile according to the selected drive mode—subtle and composed in Comfort mode, whilst unleashing a raw, visceral V8 growl in Sport mode.

Chassis and Handling

Chassis calibration represents a core focus of the 2026 facelift. The vehicle comes standard with AMG RIDE CONTROL+ enhanced air suspension and an adaptive damping system. The suspension dynamically adjusts ride height according to the drive mode: lowering automatically at high speeds to reduce aerodynamic drag and fuel consumption, or raising by 55 mm in Off-road mode to clear rough terrains. It is also equipped with the AMG ACTIVE RIDE CONTROL active roll stabilization system, which monitors body dynamics at high frequencies to effectively eliminate cornering body roll. Drivetrain duties are handled by the fully variable AMG Performance 4MATIC+ all-wheel-drive system, capable of stepless torque distribution between the front and rear axles, paired with a standard electronic rear-axle differential lock. The chassis features double-wishbone independent suspension at both the front and rear, matched with an electric power steering setup.

Cabin and Equipment

Inside, the AMG GLS 63 features a practical 2+3+2 seven-seater layout. The third row comfortably accommodates adults up to 175 cm in height for short journeys, while boot capacity starts at 355 litres, expanding to a massive 2,300 litres with the rear rows folded flat. The front cockpit is headlined by a dual 12.3-inch high-definition widescreen display running the second-generation MBUX infotainment system. Driven by the MB.OS vehicle architecture, it supports over-the-air (OTA) software updates. In-car entertainment is elevated by a Burmester high-end 3D surround sound system. Comfort amenities include a panoramic sliding sunroof, Nappa leather-wrapped multi-function steering wheel, and ambient lighting. Rear passengers can effortlessly manage seat adjustments, multi-zone climate control, and multimedia functions via a dedicated MBUX rear smart tablet.

Safety and Intelligent Driving

In terms of safety, the AMG GLS 63 is equipped with a comprehensive airbag system throughout the cabin, including front airbags, front side airbags, and full-length curtain airbags. Active safety is comprehensive, featuring Active Brake Assist (AEB), Active Blind Spot Assist, and Lane Keeping Assist as standard. For intelligent driving, the vehicle comes equipped with a Level 2 driver assistance suite, encompassing full-speed adaptive cruise control, active lane change assist, lane centering assist, automated parking assist, and traffic sign recognition. A real-time transparent bonnet off-road camera view displays the terrain directly beneath the engine bay and the forward path during off-road excursions. Reinforced driveshafts and structural chassis enhancements further bolster overall passive safety protection.

Market Performance and Review

The AMG GLS 63 commands a distinctive presence in China's million-yuan luxury SUV sector. In 2025, over 145,000 vehicles priced above the one-million-yuan threshold were sold in China, with the Mercedes-Benz GLS range (including Maybach GLS) accounting for 8,320 units. However, the AMG GLS 63 faces notable pricing pressure at the dealer level—with reports highlighting showroom discounts of up to RM496,400, bringing prices down from RM2,471,000 to RM1,974,600. Nevertheless, actual on-the-road transaction prices often exceed RM2,800,000 due to mandatory optional extras and dealer packages. Within the segment, its chief rival is the BMW X7 M60i (listed at RM1,729,000). In comparison, the AMG GLS 63 holds clear advantages in power output (450 kW vs 390 kW) and wheelbase (3,135 mm vs 3,105 mm), while offering a standard seven-seat layout. In professional evaluations, "Car and Driver" awarded the 2026 AMG GLS-Class an overall rating of 8.5/10, praising its "seemingly endless power, gorgeous interior appointments, and room for the whole family." As the flagship heavyweight of the AMG lineup, the AMG GLS 63 blends twin-turbo V8 character, generous seven-seater versatility, and authentic AMG performance pedigree, offering an extraordinary proposition for high-net-worth families seeking an all-in-one luxury flagship in the modern era.
