The Mercedes-Benz GLS stands as a definitive benchmark for those seeking the ultimate full-size luxury SUV experience before stepping into ultra-exclusive ultra-luxury territory. As Mercedes-Benz’s flagship 7-seater SUV, the GLS flawlessly bridges the gap between everyday family utility and upper-echelon luxury. Competing head-to-head with elite peers like the BMW X7, Audi Q7, and Volvo XC90, this commanding vehicle brings an authoritative presence to the road, backed by state-of-the-art engineering, high-caliber powertrains, and sophisticated technology.
Command and Sophistication
There is no denying the sheer scale of the Mercedes-Benz GLS. It possesses an imposing footprint that commands immediate attention, offering a level of road presence surpassed only by commercial vehicles.
Up front, the fascia is undeniably intimidating, centered around a wide, heavily raked radiator grille featuring dual horizontal louvers that emphasize its rugged yet premium DNA. Sleek LED headlights flank the grille, integrating multiple striking LED daytime running light elements and a prominent main projector unit. Choosing the optional AMG Line package amplifies its sporty character, replacing standard exterior chrome elements with blacked-out trim accents and aggressive body sculpting.
From the side profile, the GLS maintains a surprisingly clean, understated aesthetic despite its gargantuan dimensions. A flat roofline ensures maximum interior headroom, complemented by subtle body creases and minimalist chrome trim. Both the standard and AMG Line models ride on stunning 21-inch alloy wheels featuring an elegant star-shaped pattern. At the rear, the design remains wide and tall, anchored by clean tail light graphics and integrated, decorative dual-exhaust surrounds.
Buyers can select from five elegant monotone exterior paint shades:
- Polar White
- Obsidian Black
- High-tech Silver
- Selenite Grey
- Sodalite Blue
An Opulent, Tech-Laden Cabin
Stepping inside the Mercedes-Benz GLS reveals an environment crafted to true flagship standards. The dashboard layout utilizes horizontal architecture seamlessly integrated with sleek quad air vents and expansive digital displays. Material choices are exemplary, characterized by premium leather draping across the dash, door cards, and central armrest, paired with high-quality buttons that provide satisfying tactile feedback.
Front Row Comfort and Technology
Due to the SUV’s tall stance, entering the cabin requires stepping upward, though an exterior side step assists occupants. Once inside, the driver and front passenger are treated to plus-sized, highly bolstered seats featuring multi-way power adjustment and memory functionality. The driving position sits high, providing an expansive view over the upright hood, which instills instant confidence behind the wheel.
The tech showcase centers around twin 12.3-inch high-resolution displays acting as the digital instrument cluster and the primary MBUX touchscreen infotainment system. Wireless Apple CarPlay and Android Auto come standard. If the main touchscreen is out of comfortable reach, users can seamlessly navigate menus via the touch-sensitive steering wheel pads or the console-mounted trackpad. Audio entertainment is driven by a phenomenal 13-speaker Burmester surround sound system.
Second and Third Row Experience
The second row is engineered for supreme passenger indulgence, especially when equipped with the Rear Comfort Package Plus. This configuration includes plush headrest pillows, an extended central armrest with integrated storage, and a dedicated control tablet.
Passengers enjoy power-sliding and reclining seats, dedicated climate zones, and individual entertainment screens mounted to the front seatbacks with HDMI and Bluetooth headphone connectivity. Furthermore, the panoramic sunroof and integrated power sunblinds can be operated directly from the rear seats.
Accessing the third row requires utilizing the power-folding second-row seats, which glide forward deliberately. While headroom is generous due to the flat roofline, legroom and foot space are tight for taller adults, making the reclinable third-row seats best suited for children.
Storage and Utility
Practicality remains a high priority within the GLS cabin:
- Generous Small-Item Storage: Features wide door pockets, a deep glovebox, and adjustable cupholders.
- Abundant Charging Options: Outfitted with 11 USB Type-C ports distributed across all three rows alongside a 12V boot socket.
- Flexible Cargo Area: The trunk accommodates multiple cabin suitcases even with all seats raised. Power-folding buttons flat-lay the third and second rows to create an expansive, seamless loading floor. An electronic button in the cargo area lowers the rear air suspension to ease heavy lifting.
Effortless Performance on Any Terrain
The mechanical heart of the Mercedes-Benz GLS consists of two highly refined 3.0-liter turbocharged inline-six engine options, both mated to an ultra-smooth 9-speed torque-converter automatic transmission and a permanent 4MATIC all-wheel-drive (AWD) system. Performance and efficiency are further enhanced by a 48V mild-hybrid system, capable of contributing an auxiliary 20 hp and 200 Nm of torque.
| Engine Type | 3.0L Turbo-Petrol (450 4MATIC) | 3.0L Turbo-Diesel (450d 4MATIC) |
|---|---|---|
| Cylinders | Inline-6 | Inline-6 |
| Peak Power Output | 381 PS | 367 PS |
| Peak Torque Output | 500 Nm | 750 Nm |
| Mild-Hybrid Assist | 20 PS / 200 Nm | 20 PS / 200 Nm |
| City Fuel Mileage | 7-9 kmpl | ~10 kmpl |
| Highway Fuel Mileage | 10-12 kmpl | 12-14 kmpl |
Drive Dynamics and Powertrain Behavior
The 3.0-liter turbo-petrol variant delivers whisper-quiet refinement. In urban driving, it creeps smoothly off the line, executing seamless gear changes that remain virtually unnoticeable. On open expressways, it propels the heavy SUV to triple-digit cruising speeds effortlessly, delivering strong, linear acceleration when overtaking.
The 3.0-liter diesel variant stands out as an incredibly refined oil-burner. Generating a massive 750 Nm of torque low in the rev range, it effortlessly handles heavy loads without needing to cross the 2,000 rpm mark in daily commuting. It serves as an exceptional cross-country cruiser, balancing immense pulling power with superior highway fuel efficiency.
Ride, Handling, and Dynamics
Equipped with an advanced active air suspension system, the GLS handles highway undulations, expansion joints, and high-speed floating surfaces beautifully, eliminating long-distance travel fatigue. At lower city speeds, however, the suspension can feel slightly firm over sharp potholes or deep ruts, transferring minor cabin vibrations to the rear passengers unless approached at a slower pace.
When it comes to handling, the steering wheel is nicely weighted and predictable. Despite its high center of gravity and immense weight, the chassis tracks remarkably flat through corners, maintaining confidence along winding mountain passes or sweeping highway off-ramps.
Uncompromised Safety and Driver Assistance
Safety is paramount in the GLS, which comes equipped with an extensive suite of active and passive safety features:
- Seven comprehensive airbags and robust ISOFIX child seat anchorages.
- 360-degree surround-view camera system paired with automated parking assistance.
- Electronic Stability Control (ESC), Traction Control, and high-performance all-wheel disc brakes.
- Level 2 Advanced Driver Assistance Systems (ADAS), including Lane Keep Assist and Adaptive Cruise Control optimized for highway cruising.
Final Verdict
The Mercedes-Benz GLS fulfills its mission as a flagship luxury SUV with flying colors. It does not attempt to be a loud conversation starter; instead, it offers traditional, uncompromising Mercedes-Benz indulgence in an incredibly spacious package. With robust powertrain choices, a beautifully insulated cabin, and immense road presence, it more than justifies its premium positioning.
If you are looking for an alternative that prioritizes sharp, enthusiast-oriented driving dynamics, the BMW X7 is worth considering. Conversely, if value is a core priority, the Audi Q7 offers a similar three-row footprint at a significantly lower price point, albeit with a less opulent second-row experience. Ultimately, for those who want their luxury grand, comfortable, and commanding, the Mercedes-Benz GLS remains an elite choice.
