2026 Mercedes-Benz GLS

The flagship Mercedes-Benz GLS still brings luxury swagger to the full-size segment, effectively translating European sedan styling and performance into an SUV. Under the hood, nothing changes for the 2026 model, but Mercedes-Benz offers new Manufaktur Editions ($12,250 on the GLS 450 $10,600 on the GLS 580) that include Silicon Grey and Moonlight White Magno paint choices. The high-end Maybach GLS gets a new design package. The AMG GLS remains unchanged. While smaller than some in the category, the GLS elegantly conveys its three rows while not feeling oversized or bulky. With on-road driving that excites, the GLS also offers off-road chops, proving itself a well-rounded family vehicle with style for days.

Even on the base model GLS 450 you get good bang for your buck and a luxury ticket under six figures. That price undercuts the Range Rover LWB by over $30,000.

As understated elegance should be, driving the GLS evokes the word “effortless.” It offers smooth, substantive power, even in its base model with its turbocharged inline 6-cylinder engine that delivers 375 horsepower. However, if you’re looking for added gumption, you’ve got options. The GLS 580 gets a 510 hp 4.0-liter twin-turbo V8. Both the GLS 600 and AMG GLS 63 squeeze even more power out of the same mill at 550 hp and 603 hp, respectively.

The GLS combines confident dynamics with comfort and composure on the road. There are distinct driving modes, including Eco, Comfort, Sport, Off-Road, and Individual, that help you customize the drive to your needs, and each feels singular. Its 4MATIC all-wheel-drive system provides extra grip and stability in inclement weather and off-road conditions. Even though the GLS has three rows, its relatively diminutive size in the segment makes it a great choice for a larger crew while still offering a pleasurable and exciting driving experience.

The interior of the Mercedes-Benz GLS shines with the amenities and fabrics one might expect from the German automaker. Options for open-pore wood trim and sumptuous leathers abound, but the base model doesn’t feel overlooked either. The seats are comfortable and stylish with good support, and are available with massage functionality, too.

The GLS offers seating for up to seven passengers when configured with a second-row bench, or a total of six if you opt for dual captain’s seats in the second row. Those can be upgraded with the Executive Rear Seat Package Plus ($3450), which adds heating and ventilation. If you opt for the Manufaktur Signature Interior Package, buyers must also opt for the former. With the latter, you get a massage function, a wireless charger, and MBUX capable tablet for the second row. When it comes to leg room in the third row, the GLS (34.6 inches) offers more than the BMW X7’s 33.3 inches and less than the Land Rover Range Rover LWB with its 35.8 inches.

Cargo space in the GLS also outdoes the BMW X7 with its 17.4 cu ft behind the third row compared to the X7’s 12.8. The Range Rover LWB, however, eclipses the GLS with its 92.8 cu ft compared to the 84.7 of the Mercedes-Benz.

Well-appointed seating: Regardless of row, the GLS seats are comfortable. They come standard with heating and ventilation in the first row, with the option for both in the second row. The third row, while on the smaller side, doesn’t make you feel like an afterthought.

Burmester audio system: The GLS comes standard with an excellent 13-speaker Burmester audio system. If music is your jam, you can get an optional 26-speaker system instead. Both are music to our ears.

Standard safety features: Advanced systems including Active Lane Keeping Assist, Active Lane Change Assist, Active Brake Assist with Cross-Traffic Function, and Active Stop-and-Go Assist come standard. You also get a surround-view camera system and an anti-theft alarm.
