TL;DR The updated Mercedes GLS brings mild design changes, a new MBUX Superscreen infotainment system, improved hybrid engines and enhanced driver tech. While it remains one of the largest and most luxurious SUVs on sale, some standout features like the illuminated bonnet badge and V8 engine won’t be available in the UK.
A familiar look, now sharper and smarter
Mercedes-Benz has given its flagship GLS SUV another update, refining rather than reinventing a model that first arrived in 2019. Much like the 2023 refresh, this facelift focuses on subtle design tweaks and improved technology.
The exterior changes are understated but effective. New lighting signatures introduce star-pattern details front and rear, while revised bumpers and grille elements keep the GLS looking current. A strip of black trim now connects the rear lights, visually stretching the already massive proportions even further.
New paint finishes and alloy wheel designs add extra scope for personalisation, but the overall shape remains unchanged this is still very much the imposing, road-dominating SUV buyers expect.
A cabin dominated by screens and comfort
Inside, the GLS sees its biggest leap forward. Mercedes has fitted its MBUX Superscreen as standard, combining three 12.3-inch displays beneath a single glass surface to create a clean, high-tech dashboard.
Rear passengers are equally well catered for, with twin 11.6-inch screens turning the second row into a proper entertainment space. Seven electrically adjustable seats come as standard, alongside a panoramic roof that helps the already spacious cabin feel even more open.
Material choices have also been refreshed, including a new ‘Beech Brown’ interior option and a mix of wood or aluminium trims. Importantly, Mercedes has moved back towards physical controls on the steering wheel - an acknowledgment that not every driver appreciated the previous touch-sensitive setup.
More efficient engines and intelligent ride tech
Under the surface, the GLS gets meaningful upgrades to both efficiency and comfort. Diesel models now feature an electrically heated catalyst to improve emissions performance, while mild-hybrid technology is standard across the range, including the petrol GLS 450.
A more powerful V8 sits in the GLS 580, producing 530bhp, although this version is not expected to be offered in the UK.
Every model benefits from improved sound insulation and air suspension as standard, reinforcing the GLS’s focus on comfort. For those wanting even more refinement, Mercedes’ ‘E-Active Body Control’ system can read the road ahead, prepare for potholes and even share data with other vehicles - making rough roads feel far less intrusive.
Prices are expected to rise slightly from the previous £110,800 starting point, with AMG and Maybach versions likely to follow.
This facelift doesn’t radically change the GLS, but it keeps it competitive where it matters. With smarter tech, a more advanced cabin and improved efficiency, Mercedes’ largest SUV continues to deliver effortless luxury at scale.
