The luxury SUV arms race has entered a new phase, and Mercedes-Benz wants you to know the battle is no longer fought with leather, chrome, and horsepower alone. The refreshed GLE and GLS arrive with smoother inline-six engines, smarter software, and enough artificial intelligence to make your smartphone feel outdated.

At first glance, the updates appear subtle. The GLE’s familiar silhouette remains intact, while the rakish GLE Coupé still leans hard into its sportier mission. The GLS, meanwhile, continues its role as the rolling executive lounge of the lineup—the S-Class of SUVs, as Mercedes likes to remind everyone. But beneath the sheetmetal, Stuttgart has performed one of the most comprehensive digital overhauls ever applied to its midsize and full-size luxury SUVs.
And yes, there’s still plenty of engine left in the equation.
Six Cylinders Survive the Future
In an era where downsizing and electrification have dulled the personalities of many luxury SUVs, Mercedes continues to put faith in the inline-six. Every major powertrain in the updated GLE and GLS lineup uses a six-cylinder engine paired with a 48-volt mild-hybrid system and integrated starter-generator.
The result is a drivetrain lineup that feels more sophisticated than purely electrified rivals. The ISG system quietly fills in torque at low speeds, smooths out stop-start operation, and enables coasting and energy recuperation. More importantly, it preserves the creamy, turbine-like character Mercedes inline-sixes are known for.
The bread-and-butter GLE 350 d 4MATIC produces 286 horsepower and 650 Nm of torque, enough to shove the big SUV to 100 km/h in 6.2 seconds. Step into the GLE 450 d and output climbs to 367 horsepower and a stump-pulling 750 Nm. The gasoline-powered GLE 450 delivers 381 horsepower and reaches 100 km/h in just 5.3 seconds.

Then there’s the plug-in-hybrid GLE 450 e, arguably the most interesting powertrain in the range. Pairing a turbocharged inline-six with a 135-kW electric motor, it combines strong performance with claimed fuel consumption as low as 3.2 L/100 km. In theory, it’s the version that best bridges old-school Mercedes refinement with the industry’s electrified future.
Suspension That Reads the Road Ahead
Mercedes also continues to blur the line between SUV and luxury sedan. The updated GLS features cloud-based damper control integrated into the AIRMATIC and E-ACTIVE BODY CONTROL suspension systems. In practice, the SUV can prepare itself for upcoming speed bumps before the wheels even hit them.
It sounds gimmicky until you consider the target audience. Buyers spending well into six figures on a three-row Mercedes aren’t looking for Nürburgring lap times. They want isolation. Serenity. The feeling that road imperfections simply cease to exist.

Mercedes claims rear-seat comfort improves substantially thanks to the predictive damping system, reinforcing the GLS’s mission as a luxury shuttle disguised as an SUV.
The Dashboard Is Now a Supercomputer
The biggest transformation happens inside.
The new MBUX Superscreen stretches across the dashboard under a single pane of glass, combining three 12.3-inch displays into what feels less like a traditional cockpit and more like a Silicon Valley command center. Mercedes’ latest “Zero Layer” interface prioritizes commonly used functions and recommendations without burying everything inside endless menus.
At least, that’s the idea.
More than 40 apps are available directly through the system, including gaming, streaming, and productivity services. The MBUX Virtual Assistant now uses AI-powered conversational responses capable of handling more natural dialogue. In other words, your SUV is now expected to talk back with something resembling intelligence.
Underpinning everything is the new Mercedes-Benz Operating System, or MB.OS, which essentially turns the GLE and GLS into rolling software platforms. Over-the-air updates can continuously add features, improve functions, and even unlock optional services long after the vehicle leaves the showroom floor.
Whether buyers will embrace subscription-based automotive features remains debatable, but Mercedes is clearly betting the future of luxury lies as much in software ecosystems as handcrafted interiors.
Smarter Driver Assists, Faster Parking
The tech escalation doesn’t stop there. Mercedes says the updated GLE and GLS feature ten exterior cameras, five radar sensors, and 12 ultrasonic sensors feeding data into a significantly more powerful processor.
That hardware enables upgraded driver-assistance systems under the MB.DRIVE umbrella, including enhanced DISTRONIC adaptive cruise control and improved parking automation.

The new Parking Assist system can now identify parking spaces earlier, recognize unmarked spaces, and maneuver at speeds up to 5 km/h—roughly 60 percent faster than before. For anyone who has painfully watched older self-parking systems inch their way into a spot like a nervous student driver, that improvement alone may be worth celebrating.
Luxury SUVs for the Software Age
What makes the refreshed GLE and GLS notable isn’t any single feature. It’s the sheer scope of the transformation. Mercedes hasn’t merely facelifted these SUVs—it has fundamentally repositioned them around software, connectivity, and AI-driven functionality while preserving the effortless mechanical refinement buyers still expect from the brand.
The challenge now is philosophical as much as technical. Luxury once meant silence, craftsmanship, and mechanical excellence. Increasingly, it means processors, cloud computing, and digital ecosystems.
The new GLE and GLS attempt to deliver both worlds at once.
And for now, at least, Mercedes still remembers that a luxury SUV should feel special not only when you tap the screen—but when you bury the throttle, too.
