Mercedes‑Benz unveiled the refreshed 2027 GLS, its flagship SUV, on Spain’s Costa del Sol. The update goes beyond cosmetic tweaks: the automaker replaced the vehicle’s software “brain” and outfitted the model with advanced technology and convenience features to cement its reputation as the SUV equivalent of the S‑Class.

Next‑generation MB.OS and the triple display

The most notable changes are found in the cabin. Beneath a single glass panel that stretches from the driver to the front passenger, three 12.3‑inch displays sit side by side. It’s an evolution of the MBUX Superscreen — not just larger screens but a new user experience powered by the MB.OS operating system. A digital assistant using Microsoft AI learns occupants’ habits and enables apps like YouTube and Disney+ to run in‑car. The passenger display can play video while driving, but a safety feature will dim the screen if it detects the driver’s gaze shifting away from the road.

Refined driver‑assist and digital light technology

The new GLS monitors its surroundings with 10 cameras, five radar units and 12 ultrasonic sensors. Leveraging MB.OS’s processing power, the Level 2++ semi‑autonomous system now manages acceleration, braking and steering with more natural inputs. Automated parking is roughly 60% faster than before. On the exterior, headlamp and taillamp graphics reference Mercedes’ three‑pointed star, and the GLS becomes the brand’s first SUV to adopt a digital light system that extends projection range by about 40%.

V8 evolution and refined interior updates

Powertrain output has been nudged upward. The GLS 580’s 4.0‑liter V8 now uses a flat‑plane crankshaft and is rated at 530 hp and 76.4 kg·m (about 553 lb‑ft) of torque — increases of 20 hp and 2.1 kg·m (roughly 15 lb‑ft) — and it delivers crisper throttle response. Inside, Mercedes replaced touch sliders with physical roller controllers on the steering wheel and center console for more intuitive control. New beach‑brown leather seats and natural wood trim enhance the flagship cabin’s premium feel.
