The GLS — usually just called the GLS — is Mercedes' flagship SUV, wrapping limousine-like comfort and commanding road presence into a smart, family-ready package. It pampers occupants with a hushed cabin, premium materials and intuitive tech, while still managing to feel confident and a little indulgent on the daily commute.

Standing over 5.2 metres in length with a broad, upright stance, the GLS reads as a flagship SUV that prefers understatement over flash while still commanding attention. The front fascia and muscular haunches give it a limousine-like presence that works well for airport runs and executive parking spots. Subtle differences in chrome, light signatures and wheel design distinguish the standard GLS from the Maybach and AMG variants without shouting.
The cabin balances modern tech with traditional luxury, featuring high-grade leathers, refined trim options and solid build quality that lift it above mainstream rivals. Controls are routed through Mercedes' MBUX ecosystem with useful physical shortcuts, and the seating is comfortable and well-bolstered for long distances. Optional rear executive packages and ambient lighting push the atmosphere towards true chauffeur-driven comfort when specified.
Designed to be a family hauler, the GLS offers seating for seven with a claimed boot of 355 litres with all seats in use and up to 2,400 litres with seats folded — practical for suitcases, prams and awkward furniture. The third row is best suited to children or short adult journeys, while middle-row sliding and folding functions make supermarket runs and sports clubs easier to manage. A payload around 680 kg and a large 90-litre fuel tank mean plenty of kit and long runs between fill-ups are feasible for typical owners.
The GLS behaves like a heavy luxury cruiser: air suspension and chassis software keep body motions well controlled and soak up bumps without jolting occupants. Powertrains range from the mild-hybrid six delivering about 401 hp with a 0–100 km/h time near 6.1 seconds to high-output V8s that turn the same heavy silhouette into a seriously rapid SUV. Steering and damping are tuned for composure rather than razor-sharp feedback, resulting in confident stability at speed and predictable behaviour in corners.
Fuel consumption is typical for a large, heavy SUV: the petrol MHEV six sits around 10.1 L/100 km, the big V8s climb into the mid-teens, and the diesel variants can return about 7.8 L/100 km. With the 90-litre tank that equates to theoretical ranges of roughly 890 km for the petrol six and over 1,100 km for the frugal diesel in ideal conditions, though real-world driving will usually bring those figures down. Buyers should weigh fuel cost and emissions against the GLS's capability and long-distance comfort.
MBUX provides a sharp central screen, responsive voice control and a logical array of menus that integrate navigation, media and vehicle settings with minimal fuss. The GLS comes with an extensive driver-assistance suite — adaptive cruise, lane keeping, blind-spot monitoring and automated parking aids — that reduce stress on long journeys and tight urban manoeuvres. Optional extras add augmented-reality navigation and rear-seat entertainment so technology can be tailored to either practical family use or rear-seat luxury.
The GLS is aimed at buyers who need genuine seven-seat practicality wrapped in near-limousine comfort and a prestigious badge, whether for family life, executive transport or long-distance touring. AMG and Maybach derivatives cater to those who want high performance or ultra-lux rear accommodations, while standard petrol and diesel MHEV units suit most everyday owners. Urban buyers should consider the car's size and running costs, but for motorway miles, heavy loads and first-class comfort the GLS remains a compelling choice.
