Key Points:

  • For 2026, the GLS three-row SUV starts at $91,500 (all prices include $1,250 destination fee).
  • A new Manufaktur Arctic Silver Edition on the AMG GLS63, new paint choices and new design packages for the Maybach mark the only changes to the GLS line for the new model year.

The 2026 Mercedes-Benz GLS SUV and its ultra-luxury Maybach GLS variant carry over into the new model year with two new exterior paint options, and a Manufaktur Arctic Silver Edition can be had on the performance-oriented AMG GLS63. The 2026 GLS starts at $91,500.

What’s New?

Mercedes’ largest SUV mostly carries over for 2026 in four-, six- or seven-occupant configurations. The base 450 can be optioned in new Manufaktur Silicon Grey and Manufaktur Moonlight White Magno coats. Additionally, new Night Series Exterior and Design packages are available on the Maybach GLS600. They feature exclusive color choices, darkened chrome exterior accents and black 23-inch wheels with summer performance tires.

The GLS63’s special Arctic Silver Edition comes in an exclusive Manufaktur Cirrus Silver Magno (Magno is Mercedes-speak for matte). The cosmetic package adds contrasting black-and-red accents inside and out, as well as all the gloss-black exterior accents of the AMG Night Package. Red brake calipers peek out of the SUV’s matte-black 23-inch wheels that sport red rim flanges and center-cap detailing, and the interior features red-and-black Nappa leather upholstery on quilted front seats.

Pricing and Release Date

The 2026 Mercedes-Benz GLS is on sale now. Full pricing for the lineup is as follows:

  • GLS450: $91,500
  • GLS580: $117,400
  • AMG GLS63: $152,300
  • Maybach GLS600: $181,250

Powertrain Specs and MPG

The 2026 GLS lineup uses a nine-speed automatic transmission and the brand’s 4Matic all-wheel-drive system. The GLS450 is powered by a turbocharged 3.0-liter inline-six-cylinder engine and mild-hybrid system making 375 horsepower and 369 pounds-feet of torque in total. Mercedes says it accelerates from 0-60 mph in 5.8 seconds. The 2025 model returned 19/24/21 mpg city/highway/combined; that EPA rating is expected to carry over (official estimates for the 2026 lineup are not yet available, however).

The other GLS variants utilize variations of Mercedes’ famed twin-turbo 4.0-liter V-8. In the GLS580, the mild-hybrid V-8 generates 510 hp and 538 pounds-feet; it hits 60 mph in a claimed 4.7 seconds and should return the same 14/19/16 mpg as the 2025 version.

The 603-hp AMG GLS63 churns out 627 pounds-feet of torque and has a 0-60 mph time of just 4.1 seconds. It should maintain an EPA-rated 14/18/15 mpg for 2026.

The Maybach GLS600 splits the performance equation between the GLS580 and GLS63 and goes all in on luxury. Its V-8 makes 550 hp and 568 pounds-feet, and the SUV has a claimed 4.6-second sprint to 60 mph. The EPA rated the luxury liner at 13/18/15 mpg for 2025.

Standard Safety Features and Equipment

The flagship GLS SUV comes well equipped (as it should for the price). The standard safety features across the lineup include forward collision warning with pedestrian detection, automatic emergency braking, front cross-traffic alert, adaptive cruise control, blind spot intervention, lane departure steering assist, lane change assist, emergency steering assist, road-sign recognition and a driver attention monitor. The GLS also has a self-parking feature and a standard 360-degree camera system that helps see what’s around such a large vehicle.

The base GLS450 rides on an air spring suspension with adaptive dampers and 21-inch wheels. Mercedes upholsters the inside in synthetic leather, and the interior features power-adjustable heated and ventilated front seats, four-zone automatic climate control and ambient lighting. A 12.3-inch digital instrument cluster complements a 12.3-inch touchscreen with augmented reality navigation, voice control, and wireless Apple CarPlay and Android Auto. Wireless device charging and a 13-speaker Burmester surround-sound system are also standard.

The GLS580 comes with bigger 22-inch wheels, and the price hike incorporates leather upholstery, massaging front seats with rapid heating, heated second-row seats, five-zone automatic climate control and a heated steering wheel.

The AMG GLS63 buttons down more power with a stiffer sport suspension and a limited-slip rear differential. It also features Nappa leather upholstery, active engine mounts, a Class IV trailer hitch and a performance exhaust. A head-up display is also standard in the AMG variant.

Shoppers seeking the finest in luxury without the mad power of the GLS63 can look to the ultra-luxe Mercedes-Maybach GLS600. Distinctive mono- and two-tone paint schemes and exclusive 22-inch wheel designs elevate the Maybach. It rides on Mercedes’ E-Active Body Control that proactively tweaks the suspension response at each wheel to soften bumps. The SUV’s suspension also stiffens against body roll when turning at speed, or if the GLS gets stuck, the system pumps the suspension to help loosen it.
