Powertrain Prowess: The Heart of the Beast
At the very core of the 2025 Mercedes-Benz GLS 580 4Matic lies a powertrain that masterfully balances immense power with refined efficiency. Under the sculpted hood resides Mercedes’ celebrated twin-turbocharged 4.0-liter V8 engine, a marvel of modern engineering. In this application, it delivers a formidable 510 horsepower and 538 pound-feet of torque. However, the true brilliance of this setup is augmented by a sophisticated 48-volt mild-hybrid system, known as EQ Boost. This system isn’t just a nod to electrification; it’s an integral component that can seamlessly contribute an additional 21 horsepower and a substantial 184 pound-feet of torque for short bursts, primarily aiding acceleration from a standstill or during transitional throttle inputs.
This symbiotic relationship between the robust V8 and the mild-hybrid system results in a power delivery that is not only plentiful but remarkably smooth and immediate. The nine-speed automatic transmission is a paragon of refinement, executing gear changes with an imperceptible grace during everyday driving. Yet, when the need for rapid acceleration arises – perhaps to effortlessly overtake slower traffic on an interstate or merge confidently onto a highway – the transmission responds with lightning speed, kicking down gears almost instantaneously. The V8, in turn, unleashes a deep, guttural bellow, a harmonious soundtrack to the rapid deployment of force propelling the nearly 5,900-pound German SUV. From a standstill, the GLS 580 can sprint from 0-60 mph in a mere 4.7 seconds, a truly staggering figure for a vehicle of this size and stature, firmly cementing its status as a high-performance SUV.
Power is meticulously distributed to all four wheels via Mercedes’ venerable 4Matic all-wheel-drive system, ensuring optimal traction and stability across varying road conditions. Beyond its blistering acceleration, this formidable powertrain, coupled with a robust unibody structure, endows the GLS 580 with an impressive towing capacity SUV rating of up to 7,716 pounds. This capability extends the GLS’s versatility significantly, allowing it to confidently haul substantial boats, horse trailers, or other heavy cargo, making it an ideal companion for adventurous families or those with demanding recreational pursuits. Despite its focus on power, the mild-hybrid integration does offer a slight nod to efficiency, with EPA ratings of 14 mpg city, 19 highway, and 16 combined. Real-world long-distance driving experiences often yield slightly better figures, hinting at the subtle benefits of the EQ Boost system in reducing parasitic losses and optimizing fuel consumption. This balance of brute force and thoughtful engineering is a cornerstone of its appeal within the luxury family vehicles segment.
Dynamic Capabilities: A Symphony of Comfort and Control
The driving dynamics of the 2025 Mercedes-Benz GLS 580 4Matic represent a masterclass in compromise—or, rather, optimization—between serene comfort and assured control. Central to this delicate balance is the standard AIRMATIC air suspension system, coupled with adaptive dampers. This sophisticated setup continuously monitors road conditions and driver inputs, adjusting spring rates and damping forces in real-time to provide an extraordinarily plush ride across almost any surface. Potholes and road imperfections seem to melt away beneath the large 22-inch wheels, cocooning occupants in an environment of tranquility.
However, an analytical examination reveals a nuanced characteristic. In the default “Comfort” drive mode, while the ride is exceptionally smooth, the GLS 580 can exhibit a slight degree of body motion and head toss, particularly over undulating surfaces. This sensation stems from its elevated stance, boasting 7.9 inches of standard ground clearance, which, combined with its substantial weight and soft suspension tuning, makes it feel a touch “top-heavy.” For drivers who prioritize a more composed and buttoned-down feel, particularly when transporting passengers or navigating winding roads, switching to the “Sport” setting within the “Individual” drive mode proves transformative. This firms up the air springs and dampers, perceptibly reducing body lean and enhancing the sense of control. The steering also gains a pleasing weight, although it remains largely devoid of genuine road feel, prioritizing ease of maneuverability in line with its luxury cruiser aspirations.
Crucially, the GLS’s unibody construction provides a distinct advantage over more traditional body-on-frame rivals such as the Cadillac Escalade or Lincoln Navigator. This integrated chassis design contributes to a lighter overall structure, which in turn benefits ride quality, handling precision, and overall refinement. While it may not possess the nimble agility of smaller SUVs, the GLS 580 manages its mass with remarkable grace, offering a stable and secure feeling even at higher speeds.
Beyond the asphalt, the GLS 580 4Matic surprises with a genuine, albeit modest, degree of off-road capability. The air suspension plays a pivotal role here, allowing the vehicle to raise its ground clearance by a couple of inches in “Off-road” mode, enabling it to clear various obstacles on unpaved trails. Mercedes further enhances this with an “Off-road Cockpit” screen, presenting crucial data such as individual wheel height, tire pressure and temperature, and steering angle. Moreover, innovative “forward” and “transparent hood” views utilize cameras to project what’s directly ahead and even underneath the vehicle onto the central display, significantly aiding navigation over challenging terrain. It’s important to note, however, that the standard 285/45R22 front and 325/40R22 rear Continental EcoContact6 Q MO tires are optimized more for highway quietness and ride comfort than for aggressive off-road traction, suggesting that true wilderness excursions are best left to more specialized vehicles. Nonetheless, these features provide added confidence for traversing challenging driveways or less-maintained paths, reinforcing its versatility as an executive SUV comfort vehicle.
Interior Sanctuary: Luxury, Technology, and Thoughtful Design
Step inside the 2025 Mercedes-Benz GLS 580 4Matic, and you are immediately enveloped in an environment that epitomizes Mercedes-Benz interior design. The cabin is a masterclass in material selection, craftsmanship, and ergonomic excellence, designed to be a true sanctuary for all occupants. Every surface, from the supple tan leather seats in our tester to the meticulously crafted wood and metallic accents, exudes an air of bespoke quality.
The front cabin, in particular, is a haven for the driver and co-pilot. The multi-contour front seats are exceptionally supportive, offering a wide array of adjustments to perfectly cradle occupants of various sizes. Standard head pillows add an extra layer of plushness, while the integrated massaging function, a highlight for many, transforms long journeys into spa-like experiences. It’s a testament to individual preferences that not every passenger appreciates these features, but their availability underscores Mercedes’ commitment to personalized comfort.
Dominating the dashboard are two seamless 12.3-inch digital displays. The central infotainment touchscreen runs the latest iteration of the MBUX system, a benchmark for in-car software. Its responsiveness is immediate, its graphics are crisp, and its menu structure is logically intuitive, making it remarkably easy to navigate between satellite radio, Apple CarPlay, or the embedded navigation. Control inputs are diverse: direct touch on the screen, steering wheel-mounted touchpads, or a console-mounted trackpad. While the trackpad offers an alternative, its placement does consume valuable real estate on the center console that could otherwise be utilized for additional storage, a minor ergonomic quibble in an otherwise flawlessly executed design. The second 12.3-inch screen serves as the digital instrument cluster, highly customizable with four distinct display themes, allowing drivers to prioritize information from classic gauges to a full-screen navigation map. This dedication to digital integration showcases the premium SUV features within.
Moving into the second row, the optional captain’s chairs provide individual bucket seat comfort, offering ample head, shoulder, and legroom for even taller adults. These seats are heated, and passengers can independently control their two climate zones via a small, elegant display screen with tactile hard buttons, further enhancing the personalized luxury experience. The third row, often an afterthought in many SUVs, is surprisingly accommodating in the GLS 580. It can comfortably seat two adults, offering sufficient headroom for a six-footer and adequate thigh support thanks to a well-positioned bottom cushion. This third row also benefits from its own dedicated climate zone, ensuring comfort for all passengers. However, legroom in the third row can become a pinch point if occupants in the first or second rows are particularly tall, requiring a delicate balance of seat adjustments.
Cargo flexibility is another strong suit of the GLS. With the power-folding third row seats stowed flat, the cargo hold expands from a modest 17.4 cubic feet to a very useful 84.7 cubic feet with both the second and third rows folded. This expansive capacity easily accommodates luggage for a family vacation, sports equipment, or large shopping hauls. Despite these strengths, a few minor passenger complaints arose during testing. The integrated running boards, while aesthetically sleek, are tucked in too tightly to the body to offer practical assistance for ingress and egress. Furthermore, only the passenger-side second-row seat tilts and slides forward to provide access to the third row, requiring some contortion from passengers entering from the driver’s side—a puzzling oversight in an otherwise meticulously designed cabin.
Driver Assistance and Safety: A Step Towards the Future
In the realm of advanced driver assistance systems (ADAS), the 2025 Mercedes-Benz GLS 580 4Matic offers a comprehensive suite designed to enhance safety and reduce driver fatigue. The adaptive cruise control system maintains a set distance from the vehicle ahead, while the lane keep assist actively helps center the vehicle within its lane. These systems perform admirably, providing a noticeable reduction in driver workload on monotonous highway stretches.
However, an analytical assessment reveals a notable distinction from some competitors and even other Mercedes-Benz models. While the GLS 580’s systems are highly capable, they are not yet a hands-free solution along the lines of GM’s Super Cruise or Ford’s BlueCruise. The driver is consistently required to keep their hands on the steering wheel, a policy Mercedes-Benz enforces through constant monitoring. This is particularly interesting given that Mercedes-Benz does offer its cutting-edge Level 3 Drive Pilot system in models like the S-Class and EQS, albeit currently restricted to limited Western states due to regulatory frameworks. This strategic differentiation means that while the GLS 580 is equipped with robust Level 2 ADAS, it hasn’t yet received the full semi-autonomous capabilities present in its sedan and EV brethren.
Nonetheless, the array of sensors, cameras, and radar units underpinning these systems contribute significantly to the GLS 580’s overall vehicle safety ratings. Features such as active brake assist, blind-spot monitoring, and a 360-degree camera system provide an invaluable layer of protection, particularly in crowded urban environments or when maneuvering this large SUV in tight spaces. For a vehicle frequently tasked with carrying precious cargo—family members—these robust safety features are not merely luxuries but essential components contributing to peace of mind and the overall long-distance driving experience.
