Editorial context for design, cabin, performance, practicality, and buyer notes.
Design
The 2023 facelift subtly sharpens the exterior styling of the GLS-Class. Revisions include a larger front radiator grille and a modernized front bumper housing revised air intakes. At the rear, the taillights feature a new lighting signature defined by three horizontal blocks. The vehicle rides on a substantial 3135 mm wheelbase, measuring 5209 mm in overall length, which contributes to its commanding stance. The update also introduces new wheel designs, such as a 20-inch multi-spoke alloy option finished in glossy Himalayas grey, alongside fresh paint choices for the AMG variants.
Interior
Inside, the GLS cabin maintains its focus on luxury and space with standard seating for seven. The update introduces new upholstery options, including Catalana Beige and Bahia Brown leathers. Trim materials have also been revised; glossy brown linden wood is now standard, while the MANUFAKTUR glossy black piano lacquer is newly available across the regular GLS range. The centerpiece of the dashboard is the updated MBUX infotainment system, offering three distinct display styles and seven color schemes. With the third row in place, cargo capacity is rated at 355 liters, ensuring practical utility alongside premium comfort.
Performance
The European engine lineup is fully electrified with 48-volt mild-hybrid systems, providing temporary boosts of over 20 horsepower. Petrol options include the 381-hp 3.0-liter inline-six in the 450 4Matic and the 517-hp 4.0-liter V8 in the 580 4Matic. Diesel variants consist of the 350d and 450d, delivering 313 hp and 367 hp respectively. At the top of the range, the Mercedes-AMG GLS 63 4Matic+ utilizes a twin-turbo 4.0-liter V8 generating 612 horsepower and 850 Nm of torque, enabling a 0-100 km/h sprint in just 4.2 seconds. All models utilize a 9-speed automatic transmission and 4Matic all-wheel drive.
Practicality
Built on an expansive footprint with a length of over 5.2 meters, the GLS is designed for substantial passenger hauling. The standard all-wheel-drive system and a strong towing capacity make it highly versatile for family road trips or pulling heavy loads. An available off-road configuration increases ground clearance by 30 mm and adds underbody protection, expanding the SUV's capability on rough terrain without compromising its primary role as a comfortable luxury cruiser.
Safety and tech
Technological enhancements for 2023 focus on usability and driver assistance. The updated MBUX system now includes specialized displays for off-road driving, presenting critical telemetry directly to the driver. Parking and maneuvering this large SUV are simplified by an upgraded parking assistant and a 360-degree camera system. A notable addition is the transparent hood feature, which utilizes front camera feeds to display the ground directly beneath the engine bay, helping drivers avoid hidden obstacles during low-speed maneuvers.
Buyer notes
When comparing trims, buyers should weigh the efficiency of the inline-six models against the substantial power of the V8s, noting that all engines now benefit from mild-hybrid assistance. The standard equipment list is generous, but interior materials and tech packages vary by trim. Shoppers interested in off-road capability should look for configurations equipped with the clearance-enhancing underbody protection. Keep in mind that specific engine availability and standard features can differ significantly by regional market.
