2026 Mercedes-Benz GLS

2026 Mercedes-Benz GLS in Youngstown, OH

Often referred to as the S-Class of SUVs, the 2026 Mercedes-Benz GLS stands as the ultimate expression of full-size luxury, commanding road presence, and multi-passenger utility. Refreshed with a bolder stance, a larger illuminated grille, and slimmer LED headlights, this premier three-row vehicle bridges the gap between rugged capability and first-class transportation.

Performance and Ride Quality

The GLS lineup relies on electrified performance across its powerful engine options. The GLS 450 is motivated by a 3.0-liter turbocharged inline-six engine generating 375 horsepower, while the GLS 580 steps up to a potent 4.0-liter biturbo V8 pushing 510 horsepower. Both powertrains feature a standard 48-volt mild-hybrid system that supplies an instantaneous electric boost for seamless acceleration and optimal fuel efficiency. Power routes through a 9-speed automatic transmission to the 4MATIC fully variable all-wheel-drive system. To deliver a cloud-like ride, a standard adaptive air suspension automatically adjusts to vehicle load and road conditions, while an advanced body control system scans the terrain ahead to actively counteract body roll, pitch, and lean.

Exterior and Interior Grandeur

The exterior blends aerodynamic refinement with athletic muscle, showcasing redesigned front and rear bumpers, integrated aluminum running boards, and wheel options ranging up to 23 inches.

Inside, the cabin serves as an ultra-premium sanctuary. A generous seven-seat configuration comes standard, though an available six-seat layout swaps the second row for dual power-adjustable captain's chairs. Passengers enjoy standard quilted leather upholstery, a 64-color LED ambient lighting system, and available 5-zone automatic climate control. Luxury reaches its peak with multicontour front seats offering hot-stone massage programs, alongside an optional Executive Rear Seat Package that transforms the second row into a personalized lounge complete with ventilated seats and a dedicated interface tablet.

Advanced Technology Suite

The futuristic dashboard features an expansive digital cockpit running the latest generation of the Mercedes-Benz User Experience infotainment system. Dual 12.3-inch high-resolution displays operate under a single glass surface, controlled effortlessly via steering wheel touchpads, a central touchscreen, or natural voice commands. Wireless Apple CarPlay and Android Auto are fully standard, alongside an available interior assistant that reads hand gestures. Entertainment is anchored by a standard 13-speaker Burmester Surround Sound system, with a high-end 3D spatial audio system available for an audiophile-grade cabin experience. For tight maneuvers or off-road excursions, a specialized "transparent hood" camera system projects a virtual view of the ground directly beneath the front engine bay.

Elite Safety Engineering

The GLS prioritizes absolute occupant protection, relying on a rigid unibody frame and a standard driver assistance suite. Essential safety systems include:

Active Distance Assist: Employs radar-based adaptive cruise control with automated stop-and-go capabilities.

PRE-SAFE PLUS and Sound: Detects imminent rear-end collisions to secure the cabin, while emitting a defensive audio frequency to shield passenger eardrums from impact noise.

Car-to-X Communication: Networks with surrounding vehicles to receive advanced warnings about upcoming road hazards, low visibility, or sudden traffic gridlock.

Advanced lane change assist and exit warning assist add extra layers of reassurance, ensuring all occupants remain completely shielded from the driveway to the highway.
