2027 Mercedes-Benz GLS
August 18 2026,
The S-Class of SUVs, refined for effortless Canadian luxury.
The 2027 Mercedes-Benz GLS is Mercedes-Benz’s full-size luxury SUV, a three-row, seven-passenger flagship sitting at the top of the brand’s SUV range. This model year brings a comprehensively revised range of engines, a new digital architecture built around the MBUX Superscreen, and updated exterior details led by a new grille and standing hood ornament. Two main GLS variants carry the lineup forward: the GLS 450 4MATIC with its six-cylinder engine, and the GLS 580 4MATIC with its V8, each tuned for a different kind of drive.
Above both sits the Mercedes-Maybach GLS 680, the ultra-luxury expression of the nameplate for buyers who want the flagship experience taken further. Every GLS ships with 4MATIC all-wheel drive and standard AIRMATIC air suspension, a pairing suited to the varied road and weather conditions Quebec drivers encounter through the year. Configuration and availability details are best confirmed directly with Mercedes-Benz Rive-Sud in Longueuil.
What’s New On The 2027 Mercedes-Benz GLS?

Exterior
The 2027 GLS wears a new front end anchored by a redesigned grille with an illuminated chrome surround, three horizontal fins, and a shimmering Mercedes-Benz star pattern. A standing Mercedes-Benz star sits on the hood as standard equipment, with an illuminated version available for a further personalization touch. A new front bumper and a black panel connecting the headlamps and grille give the face a cleaner, unified look.
Standard DIGITAL LIGHT headlamps use micro-LED technology, producing a larger, higher-resolution light field while running up to 50 percent more efficiently than the previous generation. At the rear, a trim element ties both taillights into one flowing element that emphasizes the GLS’s width.
At 205 inches long, 77 inches wide, and riding on a 123.4-inch wheelbase, the GLS keeps the commanding proportions expected of the segment’s flagship. A standard panoramic roof spans more than 10.8 square feet of glass across the cabin. Two new paint finishes, Dark Petrol and MANUFAKTUR Patagonia Red Metallic, join the palette, alongside two new available 21-inch wheel designs and two new optional 22-inch AMG multi-spoke wheels, useful personalization touches even in tight downtown Longueuil parking.
Interior
Inside, the redesigned dashboard is dominated by the standard MBUX Superscreen: three seamless 12.3-inch displays spanning the cabin width, including a front passenger display for entertainment on the move. The new multifunction steering wheel adds a rocker for Distance Assist DISTRONIC and a roller for volume, while round climate vents flanking the Superscreen bring ambient lighting into the layout.
New Beech Brown upholstery and two new trim finishes give buyers more ways to personalize the cabin. MB.OS runs the vehicle end to end and keeps its software current through over-the-air updates.
All three rows seat seven passengers and are power adjustable, with the third row sized for occupants up to 6’4" and reached through a power Easy Entry function. Standard seat climate control and an electric cabin air filter cover comfort for every row. Available options push further: heated third-row seats, five-zone climate control with roof-mounted vents for the third row, and the Executive Rear Seat Package Plus, adding multi-contour massage seats, MBUX remote controls, electric sun blinds, wireless device charging, and adaptive lighting.
Technology

Entertainment
The standard MBUX Superscreen puts three 12.3-inch displays under one seamless glass surface, with the MBUX Zero Layer surfacing frequently used apps much like a smartphone home screen. The MBUX Virtual Assistant, drawing on AI from Microsoft, Google, and ChatGPT, carries on multi-part conversations and appears as an animated avatar on the display. Available MBUX Navigation pairs Google Maps mapping with the Mercedes-Benz interface for route guidance, while the available MBUX Augmented Reality for Navigation and Augmented Navigation Head-Up Display project directions onto the road ahead.
For rear passengers, the available Rear Seat Entertainment package adds two 11.6-inch HD displays with streaming video and audio, controlled through the touchscreens or optional removable MBUX remote controls.
Safety
Every GLS carries a standard driver-assistance suite built around Digital Extra: MB.DRIVE ASSIST and Distance Assist DISTRONIC, supported by ten exterior cameras, up to five radar sensors, and 12 ultrasonic sensors feeding a supercomputer running MB.OS. Standard MB.DRIVE PARKING ASSIST detects open spaces on both sides of the vehicle, including unmarked ones, and can now assist when leaving a space parked manually.
Standard MB.DRIVE PARKING ASSIST 360 adds full surround-view support, and the Rim Protection Warning flags tight clearances, useful in Longueuil’s dense, snow-narrowed parking. Buyers who want more can step up to the available MB.DRIVE ASSIST PRO package for expanded assistance features.
Powertrain

The GLS 450 4MATIC runs a 3.0 L six-cylinder engine producing 375 hp and 413 lb-ft of torque, paired with an integrated starter generator adding 23 hp and 151 lb-ft through a 48-volt system for smoother low-speed response. It reaches 0-60 mph in an estimated 5.4 seconds with a top speed of 130 mph, positioned as the more efficiency-minded choice for buyers who want the GLS’s space and refinement without V8 output.
The GLS 580 4MATIC steps up to a 4.0 L V8 making 530 hp and 553 lb-ft of torque, now with a flat-plane crankshaft and a revised turbocharger for sharper response, cutting the 0-60 mph estimate to 4.6 seconds while sharing the same 130 mph top speed. Both engines pair standard with 4MATIC all-wheel drive, splitting torque from 0 to 100 percent between the axles for traction on icy, snow-covered Quebec roads.
Standard AIRMATIC air suspension with cloud-based damper control smooths bumps before the vehicle reaches them, and the GLS 580 4MATIC can add available E-ACTIVE BODY CONTROL for more precise ride management.
Versions
The 2027 GLS lineup centres on the GLS 450 4MATIC and GLS 580 4MATIC. The GLS 450 4MATIC brings the standard suite: 4MATIC all-wheel drive, AIRMATIC air suspension, the MBUX Superscreen, DIGITAL LIGHT headlamps, and the full standard driver-assistance package. The GLS 580 4MATIC adds V8 power and unlocks options unavailable on the six-cylinder, including E-ACTIVE BODY CONTROL suspension.
Above both, the Mercedes-Maybach GLS 680 brings a 5.5 L V8 with 603 hp and 627 lb-ft of torque, a Maybach-specific grille and light signature, standard Burmester 3D Surround Sound with Dolby Atmos, standard rear Executive Seats with massage function, and 23-inch Maybach forged wheels as the nameplate’s ultra-luxury expression.
