If you’re dreaming of a full-size luxury SUV that combines space, comfort, and cutting-edge tech, the 2026 Mercedes GLS 450 4MATIC SUV might just be your next best friend. Whether you need a family hauler or a posh ride for your daily cruise, this SUV blends traditional Mercedes-Benz elegance with the latest performance innovations. Let’s dive into what makes the 2026 GLS 450 4MATIC SUV stand out in the crowded luxury SUV space.
A Bold Statement in Style and Space
The design of the 2026 Mercedes GLS 450 4MATIC SUV makes it clear: this is a flagship full-size SUV tailored for those who want space without compromising on style. With a refreshed front grille, chrome accents, and the option to go bold with 23-inch wheels, the GLS doesn’t just arrive; it commands the road. The spacious three-row layout comfortably seats seven adults, with heated and ventilated power seats available in all three rows, so no one has to fend for legroom or comfort.
Inside, the cabin is pure indulgence:
- Premium leather seats with optional ventilation and massage features.
- Optional power-operated second-row captain’s chairs for a six-seat luxury set-up.
- A panoramic sunroof that floods the cabin with natural light, enhancing the airy feel.
- Ambient lighting customizable with up to 64 colors that set the perfect mood for every journey. Powertrain That Packs a Punch
Under the hood, the 2026 Mercedes GLS 450 4MATIC SUV is all about refined muscle. It comes equipped with a 3.0-liter inline-six turbocharged engine paired with a mild-hybrid EQ Boost system, producing 375 horsepower and 369 lb-ft of torque. This setup gives the GLS 450 a smooth yet powerful acceleration, hitting 0 to 60 mph in around 5.8 seconds—a surprising quickness for such a large SUV.
The 4MATIC all-wheel-drive system is standard, delivering confident traction and stability no matter the weather or terrain. Plus, the standard AIRMATIC® air suspension automatically adjusts the ride height and damping to make your drive buttery smooth whether cruising city streets or tackling light off-road paths.
For those craving even more punch, the GLS 580 4MATIC with its 4.0-liter V8 and 510 horsepower is also available, but the 450 strikes a fantastic balance of power and efficiency.
Tech and Convenience that Impress
Mercedes pulls out all the stops with technology inside the 2026 GLS 450 4MATIC SUV:
- The MBUX infotainment system features a sharp 12.3-inch touchscreen with augmented reality navigation, wireless Apple CarPlay, and Android Auto compatibility.
- Personalization shines thanks to user profiles that save your settings from driver seat positions to preferred climate control.
- Rear-seat passengers can stay entertained with optional tablet controls and dual rear entertainment screens.
- Cabin air filtration systems and ionizer-purified air work to keep the atmosphere fresh and relaxing.
- Driver assistance technologies like adaptive cruise control with stop-and-go, active lane keeping, evasive steering assist, and route-based speed adjustment offer semi-autonomous highway driving confidence. Designed for Families and Adventure
With three rows and smart seating configurations—including power-operated second and third rows and optional captain’s chairs—the 2026 GLS 450 4MATIC is built for ultimate family comfort and practicality. The cabin feels spacious and open, thanks to large windows and the glass roof that eliminates any sense of claustrophobia.
The GLS doesn’t just stop at luxury—it’s also a workhorse capable of towing up to 7,700 pounds when properly equipped, so bringing along your boat or camper is no sweat. Despite its size, parking and maneuvering are made easier with a sophisticated surround-view camera system and semi-autonomous features that even help with trailer backing.
Luxury That Goes Beyond the Basics
The refinement continues with options like the Burmester® high-end 3D surround sound system, offering crystal-clear audio with 27 speakers and 1,590 watts of output for an immersive experience. Inside, heated armrests and available massaging seats turn every ride into a first-class escape.
The cabin materials are top-shelf, and with ambient lighting tailored to your mood, the GLS creates a relaxing, elegant environment whether you’re stuck in traffic or cruising the freeway.
Pricing and Availability
Starting around $89,200 MSRP, the 2026 Mercedes GLS 450 4MATIC SUV is positioned as a premium option in the large luxury SUV segment but justifies its price with a blend of style, technology, comfort, and performance that few competitors can match.
In summary, the 2026 Mercedes GLS 450 4MATIC SUV shines as a full-size luxury SUV that redefines what it means to travel in style and comfort.
