Whether you are navigating the scenic routes through the rolling hills of Escondido, CA, or arriving at a gallery opening in the heart of the city, this flagship SUV provides an unmatched presence that commands respect and admiration.

Refined Performance and Engineering

The heart of this GLS 450 4MATIC is a sophisticated 3L I-6 engine featuring gasoline direct injection and an intercooled turbocharger. This advanced I6 Configuration is paired with a MHEV (mild hybrid electric vehicle) system, utilizing a 48V lithium-ion traction battery to ensure seamless power delivery and efficiency. Delivering a robust 375HP, the powertrain is managed by a 9-speed automatic transmission with Lock-up and Overdrive capabilities, providing effortless acceleration as you merge onto the highway or climb the coastal foothills.

The driving experience is defined by the 4MATIC all-wheel drive system, which offers permanent locking hub control for maximum confidence regardless of weather conditions. To ensure the highest level of comfort, the vehicle is equipped with an AIRMATIC automatic height adjustable suspension and an Adaptive Damping System. This Adaptive ride suspension constantly monitors the road surface, adjusting the Independent front and rear suspension in real-time. Drivers can further tailor their experience using the DYNAMIC SELECT system, which offers selectable drivetrain modes to match the terrain or your personal driving preference.

Cutting-Edge Technology and Connectivity

Step into a digital cockpit where intuition meets innovation. The dashboard is anchored by two 12.3-inch primary displays, creating a seamless glass interface for the MBUX digital/analog instrumentation display and the central infotainment hub. The MBUX Augmented Reality for Navigation transforms the way you find your way through Southern California, overlaying directional cues onto a live video feed of the road ahead. Staying connected is effortless with Apple CarPlay and Android Auto wireless mirroring, supported by a total of 9 USB ports distributed throughout the cabin.

Control is always at your fingertips—or the tip of your tongue—thanks to the MBUX voice activated audio controls and the built-in virtual assistant. For the audiophile, the Burmester Surround Sound System with a 590W amplifier and Dolby Atmos digital signal processor delivers a concert-hall experience through 13 high-performance speakers. The technological suite is rounded out by Front wireless smart device charging, Mercedes me connect Services for vehicle-to-everything (V2X) communication, and fingerprint recognition to instantly recall your personalized memory settings.

Unrivaled Interior Comfort and Craftsmanship

The interior of the GLS 450 4MATIC is a masterclass in luxury, featuring a stunning Bahia Brown/ Black MB-Tex upholstery complemented by Brown Linden Wood Trim. With a 7-Seat Configuration, there is ample room for the whole family, including Power folding second-row seats and Power reclining third-row seats that can fold into the floor at the touch of a button. The Heated and Ventilated Power Front Seats feature 4-way power lumbar support and 3 memory settings that include the position of the Nappa leather and genuine wood steering wheel and the exterior mirrors.

Climate comfort is prioritized for every passenger through a Rear climate control system with separate controls, supplemented by Rear headliner/pillar ducts and Under seat ducts. The sense of openness is enhanced by the Panorama power moonroof, which spans the first and second rows. Thoughtful details abound, from the Illuminated front beverage holders to the HANDS-FREE ACCESS power liftgate. Every journey is made easier with KEYLESS GO push-button start and the SmartKey remote, which allows for remote window and sunroof control before you even step inside.

Comprehensive Safety and Driver Assistance

Mercedes-Benz continues its legacy of protection with a suite of active and passive safety systems. The Active Distance Assist DISTRONIC provides adaptive cruise control with stop-and-go functionality, while Active Lane Keeping Assist and Active Blind Spot Assist provide a vigilant layer of awareness. The vehicle features an Aerial view camera system, combining front, rear, and side cameras to provide a 360-degree perspective of your surroundings, making parking in tight spaces effortless.

In the event of an impending collision, the PRE-SAFE PLUS system initiates automatic post-collision braking, while Active Brake Assist provides forward collision mitigation and pedestrian detection. The cabin is protected by a sophisticated 7-airbag system, including Curtain overhead airbags for all three rows and a Driver side knee airbag. Additional peace of mind comes from the ATTENTION ASSIST driver attention monitor and Traffic Sign Assist, which helps you stay informed of local speed limits and road conditions automatically.

Sophisticated Exterior Design

Dressed in Obsidian Black Metallic, this GLS 450 4MATIC features the aggressive AMG Line Exterior Package. The profile is defined by 21-inch AMG Twin 5-Spoke Wheels with Black Accents and Illuminated Brushed Aluminum Running Boards that facilitate easy entry and exit. The Night Package adds a bold touch with blacked-out exterior accents, including Black side window trim and Black door mirrors, contrasting beautifully against the Dark chrome grille.

The lighting system is equally impressive, featuring the LED Intelligent Light System with Directionally adaptive headlights and Adaptive Highbeam Assist. These projector-beam units work in tandem with LED daytime running lights and LED brake lights to ensure maximum visibility. Functional elements like the Roof rails, which support a maximum load of 198.4 lbs, and the Rear lip spoiler blend utility with the vehicles aerodynamic silhouette.
