Mercedes-Benz is updating its largest SUV, the GLS, for the 2027 model year, bringing significant design and technology changes to what the brand calls the “S-Class of SUVs.” The GLS, first introduced in its current form in 2019, receives a comprehensive facelift that modernizes its exterior and overhauls the interior with a focus on premium comfort and advanced features.
Exterior Overhaul
The most visible changes are to the front and rear styling. The GLS now features a bolder grille design with integrated headlight clusters, echoing trends from competitors like BMW. The headlights themselves use Mercedes-Benz’s latest Digital Light LED technology. The iconic three-pointed star logo is prominently displayed, appearing as an illuminated ornament on the hood and integrated into the grille pattern and tail lights. New exterior finishes, including Dark Petrol flat and Manufaktur Patagonia Red metallic, will also be available.
Interior Revolutionized
The interior receives the most substantial updates, headlined by the standard MBUX Superscreen. This system combines a 12.3-inch digital instrument cluster, infotainment touchscreen, and a passenger display under a single curved glass panel. The passenger display activates only when someone is seated, otherwise showing the signature star pattern. Optional rear-seat entertainment systems with 11.6-inch HD displays are also available.
Mercedes-Benz has redesigned the dashboard with round air vents, a signature design element, and added new metallic controls to the steering wheel. Interior details include new seat stitching, available vibrating massage functions, and new wood inlays.
Performance and Efficiency Updates
Under the hood, both the GLS580 (V8) and GLS450 (inline-six) receive performance tweaks. The V8 engine gains a flat-plane crankshaft to meet future emissions standards, boosting output to 395kW and 750Nm. The inline-six engine now produces 560Nm of torque. All GLS models are equipped with a 48V mild-hybrid system for improved fuel efficiency.
Mercedes-Benz also focused on reducing noise and vibration by adding additional insulation to the engine compartment and transmission tunnel. The Airmatic air suspension has been retuned for a sportier feel, while the 48V E-Active Body Control system remains an available option for even greater ride control.
Advanced Driver Assistance
The GLS receives enhancements to its suite of safety and driver-assist features. The MB Drive Parking Assist system can now park the vehicle diagonally and in unmarked spaces. Semi-autonomous driving capabilities are available in varying levels, from MB Drive Standard to MB Drive Assist Pro (initially available in China and the US), offering point-to-point automated driving in dense city traffic.
Dimensions and Practicality
The 2027 GLS retains its spacious dimensions, measuring 5.2 meters long with a 3.13-meter wheelbase. The three-row seating configuration offers power-adjustable seats for all passengers, with the third row accommodating adults up to 1.94 meters tall.
The updated Mercedes-Benz GLS aims to cement its position as the benchmark for luxury SUV comfort and technology, blending the opulence of the S-Class sedan with the practicality of a large, three-row vehicle.
