Mercedes-Benz GLS 580 Review: The S-Class of SUVs

As Bryan Bowman from MercedesBlue, I’ve had the pleasure of experiencing many Mercedes-Benz vehicles, and the GLS 580 consistently leaves a lasting impression. It’s more than just a large SUV; it’s a mobile sanctuary designed for those who demand the absolute best. From its commanding presence on the road to the serene cabin experience, the GLS 580 redefines what a family vehicle can be. Let’s dive deep into what makes this luxury SUV so special.
Under the Hood: Power Meets Efficiency
The heart of the GLS 580 is its dynamic powertrain. Mercedes-Benz has equipped this powerhouse with a twin-turbocharged 4.0-liter V8 engine. What sets this engine apart is its integration with the EQ Boost mild-hybrid system. This isn’t just about raw power; it’s about intelligent power delivery.
The EQ Boost system uses an integrated starter-generator that can provide an extra 21 horsepower and 184 lb-ft of torque for short bursts. This means smoother acceleration, quicker responsiveness, and a more refined driving feel, especially at lower speeds and during take-off. It also contributes to slightly improved fuel efficiency, a welcome addition for an SUV of this size.
Coupled with Mercedes-Benz’s renowned 9G-TRONIC automatic transmission, shifts are almost imperceptible. The engine’s output is seamlessly managed, ensuring that power is always available when you need it, whether you’re merging onto a highway or overtaking slower vehicles. The sound of the V8 is present but never intrusive, adding a subtle hint of performance without compromising the cabin’s tranquility.
Performance and Driving Dynamics
Driving the GLS 580 is an experience in controlled power. The standard AIRMATIC® suspension system plays a crucial role here. It works tirelessly to adapt the damping to the road conditions, ensuring a plush ride that isolates occupants from bumps and imperfections. This system also allows you to adjust the ride height for easier entry and exit or to provide more ground clearance for light off-road adventures.
For those who crave a more engaging drive, the optional E-ACTIVE BODY CONTROL® (now part of the enhanced DRIVE PILOT system on newer models) takes things to another level. This advanced active suspension system can individually control the spring and damping forces at each wheel, counteracting body roll in corners and smoothing out rough surfaces remarkably well. It’s a sophisticated piece of engineering that makes a large SUV feel surprisingly nimble.
The GLS 580 comes standard with 4MATIC® all-wheel drive, providing excellent traction and stability in all weather conditions. The system intelligently distributes power to the wheels with the most grip, enhancing both safety and driving enjoyment.

Interior: A Haven of Luxury and Technology
Step inside the GLS 580, and you’ll immediately understand why it’s called the “S-Class of SUVs.” The cabin is meticulously crafted with the finest materials. Supple Nappa leather, genuine wood trim, and brushed metal accents create an atmosphere of pure indulgence. Every surface feels premium to the touch, and the build quality is exceptional.
Seating is a highlight, with generous space for up to seven passengers across three rows. The front seats are particularly inviting, offering heating, ventilation, and a multitude of power adjustments with memory settings. The second row is equally comfortable, with ample legroom and amenities. What truly impresses is the third row; it’s one of the most spacious in its class, making it genuinely usable for adults on shorter journeys, not just children. Power-folding functionality for the second and third rows further enhances versatility.
The dashboard is dominated by the stunning MBUX (Mercedes-Benz User Experience) infotainment system. It features two large, seamlessly integrated 12.3-inch displays – one for the digital instrument cluster and another for the central touchscreen. The system is intuitive, responsive, and incredibly feature-rich, offering navigation, media control, climate settings, and vehicle information. Voice control, activated by saying “Hey Mercedes,” allows for natural language commands, making it easy to adjust settings without taking your hands off the wheel.
For audiophiles, the standard Burmester® surround sound system delivers an immersive listening experience, filling the spacious cabin with crystal-clear audio. Optional upgrades can further enhance this, but the standard system is already superb.
Technology and Safety Features
Mercedes-Benz is at the forefront of automotive technology, and the GLS 580 is a testament to this. Beyond the MBUX system, you’ll find a plethora of driver assistance systems designed to enhance safety and reduce driving fatigue. These include:
- Active Distance Assist DISTRONIC®: A sophisticated adaptive cruise control system that can manage speed, braking, and even steering in certain situations.
- Active Steering Assist: Helps keep the vehicle centered in its lane, especially on highways.
- Active Blind Spot Assist: Warns you of vehicles in your blind spots and can intervene to prevent lane changes.
- Active Brake Assist: Uses sensors to detect potential collisions with other vehicles, pedestrians, or cyclists and can apply braking automatically if necessary.
- PRE-SAFE® System: A suite of features that can help protect occupants if a collision is imminent, by adjusting seats, closing windows, and tightening seatbelts.
- 360° Camera: Provides a bird’s-eye view of the vehicle and its surroundings, invaluable for parking and maneuvering in tight spaces.
The standard LED Intelligent Light System also adapts to driving conditions, providing optimal illumination without dazzling other drivers. For parents, the child safety features, including LATCH anchors in the second and third rows, are robust and easy to access.
The commitment to safety is further evidenced by its performance in crash tests conducted by organizations like the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety, where vehicles of this caliber typically perform very well.
Space and Versatility: Family-Friendly and Functional
The GLS 580 is built for those who need space. With its ability to comfortably seat seven, it’s an ideal choice for larger families or for transporting friends and colleagues. The 60/40 split-folding second-row seats and the 50/50 split-folding third-row seats offer incredible flexibility for cargo. When all seats are folded down, you reveal a cavernous cargo area perfect for hauling everything from luggage for a family vacation to large purchases from a home improvement store.
Cargo volume figures speak for themselves:
| Seating Configuration | Cargo Volume (Approx.) |
|---|---|
| Behind 3rd Row | 12.0 cu ft |
| Behind 2nd Row | 42.7 cu ft |
| Behind 1st Row (Max) | 84.7 cu ft |
The power liftgate makes loading and unloading easier, and the optional trailer hitch allows for towing up to 7,700 pounds, making it capable of handling anything from jet skis to a small camper. For everyday family use, the ease of access, the numerous cupholders, and the available rear-seat entertainment system ensure that passengers remain comfortable and entertained.
