Powertrain and Performance: A Symphony of Power and Efficiency
At the heart of the 2025 Mercedes-Benz GLS 580 4Matic lies an engineering marvel: Mercedes’ revered twin-turbocharged 4.0-liter V8 engine. In its current iteration, this powerplant delivers a robust 510 horsepower and 538 pound-feet of torque. What truly sets this system apart, however, is its seamless integration with a sophisticated 48-volt mild-hybrid system, often referred to as EQ Boost. This intelligent electrification can momentarily contribute an additional 21 horsepower and a substantial 184 pound-feet of torque, primarily to aid initial acceleration and provide a silken transition through stop-start scenarios.
The synergy between the potent V8 and the EQ Boost system is palpable. During long stretches of highway driving, a real-time power meter often indicates that only a fraction of the available horses are being utilized, underscoring the V8’s effortless cruising capability. Yet, when the need arises for immediate acceleration—whether for overtaking slower traffic or merging onto a bustling freeway—the system responds with an immediacy that belies the vehicle’s substantial 5,875-pound curb weight. The nine-speed automatic transmission, a hallmark of Mercedes-Benz’s powertrain philosophy, orchestrates gear changes with remarkable precision and fluidity. Its quick kick-down capability ensures that peak power is always accessible, accompanied by a satisfyingly deep bellow from the V8, a subtle reminder of the formidable forces at play. This harmonious blend propels the GLS 580 from 0 to 60 mph in a swift 4.7 seconds, a figure that places it firmly in the realm of performance sedans, let alone full-size luxury SUVs.
Power distribution is handled by Mercedes’ proprietary 4Matic all-wheel-drive system, which dynamically allocates torque to all four wheels, optimizing traction and stability in varying conditions. This robust drivetrain, combined with the inherently strong unibody structure of the GLS 580, translates directly into impressive practical capabilities. The GLS 580 boasts a substantial towing capacity of up to 7,716 pounds. This figure is not merely theoretical; it signifies a genuine capability to haul a sizable boat, a multi-horse trailer, or a substantial utility trailer with confidence, making it an ideal choice for owners who demand both luxury and serious utility from their premium family SUV. This blend of robust power, sophisticated delivery, and practical utility forms a core pillar of the GLS 580’s value proposition in the 2025 luxury SUV performance market.
Of course, with great power and significant mass, come considerations for fuel economy. The EPA rates the GLS 580 4Matic at 14 mpg in the city, 19 mpg on the highway, and 16 mpg combined. Our extensive real-world testing, covering nearly a thousand miles, consistently yielded figures slightly above the EPA highway rating, averaging 19.4 mpg. While these numbers might seem modest in an era increasingly focused on electrification, it’s crucial to contextualize them against the vehicle’s prodigious power output, considerable size, and the inherent demands of a twin-turbo V8. For an executive SUV interior of this caliber, delivering this level of performance, the fuel efficiency represents a considered balance, rather than a deficiency.
Ride, Handling, and Dynamic Refinement: The Art of the Smooth Journey
Mercedes-Benz has long been synonymous with ride comfort, and the 2025 GLS 580 4Matic exemplifies this heritage through its standard AIRMATIC air suspension system paired with adaptive dampers. This advanced setup continuously adjusts damping forces at each wheel, responding to road conditions and driving style to maintain an exceptionally smooth and composed ride across diverse surfaces. The air springs also offer the practical benefit of variable ground clearance, enhancing its versatility.
During our evaluation, the “Comfort” drive mode delivered an undeniably plush ride, effectively isolating occupants from the harshness of road imperfections. However, this sublime comfort, characteristic of Mercedes-Benz innovation, sometimes manifested as a slight top-heaviness and a degree of body lean during more spirited cornering or sudden directional changes. This can lead to a phenomenon known as “head toss” for passengers, particularly when traversing undulating roads. For a driver seeking to provide the most composed journey, especially with passengers, an adjustment was often preferred.
This is where the customizable “Individual” drive mode proved invaluable. By selecting the “Sport” setting for the suspension within this mode, the adaptive dampers firmed up noticeably, significantly reducing body roll and creating a more “buttoned-down” feel. While the GLS 580, given its size and stature, isn’t engineered to be a canyon carver, this adjustment transformed its dynamic character, imbuing it with greater confidence and control without unduly sacrificing ride quality. The steering and stability control also offer individual adjustments, though their impact is less pronounced, reflecting the vehicle’s overarching mission of luxurious comfort rather than raw, unbridled sportiness.
A key differentiator for the GLS 580, which contributes significantly to its superior ride and handling characteristics compared to some direct competitors, is its unibody construction. Unlike body-on-frame rivals such as the Cadillac Escalade or Lincoln Navigator, the GLS’s integrated chassis and body structure contribute to a lighter, stiffer, and ultimately more refined vehicle. This structural integrity minimizes flex, enhances crash safety, and allows the sophisticated suspension system to operate with greater precision, resulting in a ride that feels inherently more premium and controlled. This design choice is a crucial factor for those prioritizing long-distance comfort and sophisticated road manners in a large SUV.
Beyond the pavement, the GLS 580 also offers a modicum of off-road capability, making it a genuinely versatile choice for off-road luxury vehicle enthusiasts. The AIRMATIC suspension can raise the ground clearance by a couple of inches in “Off-road” mode, providing crucial clearance for moderate obstacles. Mercedes further enhances this with its intuitive Off-road Cockpit screen, displaying vital information such as individual wheel height, tire pressure and temperature, and steering angle. Revolutionary “transparent hood” views—leveraging exterior cameras to stitch together an image of the terrain directly beneath and ahead of the vehicle—provide invaluable situational awareness. While the standard 285/45R22 front and 325/40R22 rear Continental EcoContact6 Q MO tires are optimized for highway quietness and ride quality rather than aggressive off-road traction, these features underscore the GLS’s readiness for light trail exploration or navigating challenging conditions to reach a remote vacation home.
Interior, Technology, and Comfort: An Elevated Sanctuary
Stepping into the 2025 Mercedes-Benz GLS 580 4Matic is to enter a world where automotive luxury features are not merely options, but intrinsic elements of the design philosophy. The cabin is an expansive, impeccably crafted sanctuary, upholstered in rich tan leather that immediately conveys a sense of warmth and sophistication. Every material, from the genuine wood and metal accents to the soft-touch surfaces, speaks to a commitment to premium quality.
The driver’s seat is an exemplary blend of ergonomics and indulgence. The multi-contour front seats, complete with dynamic side bolsters, offer exceptional support for long journeys, minimizing fatigue. Standard head pillows add a layer of plushness, while the integrated massaging function can transform mundane miles into therapeutic relaxation. These features, though universally praised by many, can sometimes be a matter of individual preference; for instance, some passengers might find the head pillows too pronounced or the massage too intrusive, highlighting the subjective nature of ultimate comfort.
At the technological forefront is Mercedes’ MBUX (Mercedes-Benz User Experience) infotainment system, displayed across a vibrant 12.3-inch touchscreen. In 2025, MBUX remains one of the industry’s most advanced and user-friendly interfaces. Its responsiveness is immediate, and navigation through menus, whether for satellite radio, Apple CarPlay, or Android Auto, is intuitive. Multiple input methods are offered: direct touchscreen interaction, steering wheel controls, and a trackpad on the center console. While the trackpad offers an alternative, its placement does consume valuable real estate that could otherwise be utilized for additional storage, a minor ergonomic quibble in an otherwise brilliant setup. Complementing the central display is an equally impressive 12.3-inch digital instrument cluster, highly customizable with four distinct display themes, allowing drivers to prioritize information relevant to their current needs, from navigation maps to performance metrics. This high-end vehicle technology suite solidifies the GLS 580’s position as a leader in connected car features 2025.
However, in an era where Level 2+ hands-free driving assistance systems are becoming more prevalent, the GLS 580 exhibits a slight gap. While its adaptive cruise control and lane-keep assist system perform admirably, maintaining a consistent lane and speed with precision, they still necessitate the driver’s hands on the wheel. Mercedes-Benz does offer its advanced Level 3 Drive Pilot system in models like the S-Class and EQS, but its functionality remains geographically limited to specific Western states due to regulatory and infrastructure complexities. For a premium family SUV designed for extensive road trips, the absence of a widely available, truly hands-free system (akin to GM’s Super Cruise) is a noticeable point of critique, though its existing ADAS suite still represents a high standard for advanced driver assistance systems (ADAS).
Passenger accommodation is equally prioritized. With the capacity for up to seven occupants, the GLS 580 excels in providing ample space. The second row, often configured with captain’s chairs, delivers exceptional comfort, mirroring the supportive feel of the front seats. Heated seating and dedicated dual-zone climate controls, managed via a small, tactile display screen, ensure passenger comfort is paramount. The third row, too, is surprisingly accommodating for two adults. While legroom can become somewhat constrained if occupants in all three rows are particularly tall, the bottom cushion sits high enough to provide decent thigh support, and headroom is sufficient even for individuals approaching six feet. A dedicated climate zone for the third row further enhances long-distance comfort.
Cargo versatility is a significant advantage for the GLS 580. Behind the third row, a modest but usable 17.4 cubic feet of space is available—enough for a few gym bags or a couple of coolers. However, with the third row power-folded flat, cargo capacity expands to a very practical 48.7 cubic feet, and with both second and third rows stowed, a cavernous 84.7 cubic feet opens up, making it ideal for hauling large items or extensive luggage for family vacations. The power controls for folding the seats are a particularly thoughtful touch, simplifying the transition between passenger and cargo-focused configurations.
Minor criticisms from passengers during our extended test included the observation that the running boards are tucked too tightly to the body to be truly useful for ingress/egress. Additionally, the second-row seating arrangement, where only the passenger-side seat tilts and slides forward for third-row access, was noted as a minor inconvenience. These are small points in an otherwise masterfully executed interior, but highlight areas for potential ergonomic refinement.
