2027 Mercedes-Benz GLS: What’s New for the Flagship SUV?

There are plenty of luxury SUVs with three rows of seating, but few approach family travel the way the Mercedes-Benz GLS does. As the largest SUV in the Mercedes-Benz lineup, the GLS has long served as the brand’s flagship utility vehicle, combining generous passenger space with many of the premium materials, advanced technologies, and comfort features found throughout the Mercedes-Benz portfolio.

For 2027, Mercedes-Benz is refining that formula once again. The updated GLS receives refreshed styling, a redesigned digital experience powered by MB.OS, revised powertrains, expanded driver assistance technology, and additional personalization options. While the overall mission of the GLS hasn’t changed, the newest version brings meaningful improvements that make every drive feel even more effortless.

If you’re considering a full-size luxury SUV, the 2027 GLS is shaping up to be one of the most compelling options in its class. Until it arrives, you can browse our current Mercedes-Benz GLS inventory or explore the complete new Mercedes-Benz lineup available at Mercedes-Benz of Hoffman Estates.

Designed Around Passenger Comfort

The GLS has always been more than a larger version of the GLE. Instead, Mercedes-Benz designed it for drivers who regularly travel with family, friends, or extra cargo and don’t want to compromise on luxury. Every row receives thoughtful attention, making the GLS feel equally accommodating whether you’re sitting behind the wheel or riding in the back.

The spacious second row offers generous legroom and available heated, ventilated, and multicontour seating, while the third row is sized to comfortably accommodate adults on shorter trips. Power-folding rear seats make it easy to switch between passenger and cargo configurations, giving the GLS flexibility for everything from daily errands to weekend getaways.

Drivers looking for even greater luxury may also appreciate the available Executive Rear Seating Package, which transforms the second row into a more premium environment with enhanced comfort features designed for long-distance travel.

A Ride Tuned for Long-Distance Comfort

One of the defining characteristics of the GLS has always been the way it isolates passengers from rough pavement. Even with its full-size dimensions, the SUV is engineered to feel composed and controlled whether you’re navigating city streets or spending hours on the interstate.

Every 2027 GLS includes AIRMATIC® air suspension, which automatically adjusts ride height and damping to maintain comfort under changing road conditions. Available E-ACTIVE BODY CONTROL adds another level of sophistication by helping reduce body movement during cornering, acceleration, and braking while improving overall ride quality.

Mercedes-Benz has also introduced cloud-based suspension technology that allows the system to anticipate certain road conditions using shared vehicle data. Rather than simply reacting to bumps after they happen, the suspension can proactively prepare for changing pavement in supported areas, contributing to an even smoother ride.

MB.OS Gives the GLS a Smarter Cabin

The biggest technology upgrade for 2027 is the arrival of MB.OS, Mercedes-Benz’s next-generation operating system. The new platform powers the GLS’s infotainment system, connected services, navigation, personalization settings, and over-the-air software updates.

The latest MBUX interface has been redesigned with quicker response times, updated graphics, and a more natural voice assistant. Drivers can interact with navigation, media, vehicle settings, and connected services using conversational voice commands, reducing the need to navigate through menus while driving.

The available MBUX Superscreen stretches across much of the dashboard, giving both the driver and front passenger easier access to entertainment, navigation, and vehicle functions. Combined with the premium materials and spacious cabin, the new digital experience reinforces the GLS’s position as Mercedes-Benz’s flagship SUV.

Powertrain Options Continue to Cover a Wide Range of Drivers

Whether you’re looking for smooth everyday performance, effortless highway passing power, or the excitement of a handcrafted AMG® engine, the 2027 Mercedes-Benz GLS lineup offers a configuration to match. Mercedes-Benz continues to offer multiple powertrains, allowing buyers to prioritize efficiency, performance, or a balance of both.

The GLS 450 remains the entry point to the lineup with a turbocharged 3.0-liter inline-six engine supported by mild-hybrid technology. Drivers who want additional power can step up to the GLS 580, which pairs a twin-turbocharged V8 with an integrated starter-generator for stronger acceleration and smoother power delivery. At the top of the lineup, the Mercedes-AMG® GLS 63 delivers the highest level of performance while maintaining the comfort expected from a flagship luxury SUV.

The Mercedes-AMG® GLS 63 Continues to Set the Performance Standard

Although the GLS is designed with comfort in mind, the AMG® version proves that a full-size luxury SUV can also deliver thrilling performance. The 2027 Mercedes-AMG® GLS 63 continues to feature a handcrafted AMG® 4.0-liter V8 biturbo engine paired with mild-hybrid assistance, producing an impressive 603 horsepower and 627 lb-ft of torque.

AMG®-specific suspension tuning, performance braking components, and distinctive exterior styling help separate the GLS 63 from the rest of the lineup. Inside, AMG® seats, exclusive trim options, and performance displays reinforce its unique character without sacrificing the comfort expected from a Mercedes-Benz flagship SUV.

Technology Designed to Make Everyday Driving Easier

In addition to MB.OS, the 2027 GLS benefits from Mercedes-Benz’s latest suite of driver assistance technologies under the MB.DRIVE name. Depending on configuration, available systems can assist with highway driving, parking, lane positioning, and adaptive cruise control.

While these technologies are designed to support the driver rather than replace them, they can make longer trips and daily commutes more comfortable by reducing workload in stop-and-go traffic and on extended highway drives.

Ready for Family Trips, Weekend Getaways, and Everyday Life

One reason the GLS continues to stand out is its versatility. It offers the passenger space expected from a full-size SUV while maintaining the premium fit and finish that defines Mercedes-Benz. Whether you’re loading luggage for a vacation, transporting sports equipment, or simply making room for passengers, the flexible interior adapts to changing needs.

When properly equipped, the GLS can tow up to 7,700 pounds, giving owners the ability to bring along boats, campers, or utility trailers when adventure calls. Combined with standard 4MATIC® all-wheel drive, it’s a vehicle that’s equally comfortable on family road trips and daily commutes throughout the Chicagoland area.
