The 2023 Mercedes-Maybach GLS 600 represents the pinnacle of the Mercedes-Benz SUV lineup, offering a 550-horsepower twin-turbo V8 engine paired with an ultra-exclusive four-seat configuration. Designed as a direct competitor to the Bentley Bentayga and Rolls-Royce Cullinan, it focuses on unparalleled ride comfort through its E-Active Body Control suspension and a rear-cabin experience modeled after first-class air travel.
The Identity and Market Positioning of the Maybach GLS
The 2023 Mercedes-Maybach GLS 600 is not merely a high-trim version of the standard GLS-Class; it is a fundamental reimagining of what a luxury SUV should prioritize. While the standard GLS is a three-row family hauler, the Maybach version deliberately sacrifices the third row to provide the second-row passengers with unprecedented legroom and reclining capabilities. This vehicle is targeted at a specific demographic: the chauffeured executive or the ultra-high-net-worth individual who requires the ride height and presence of an SUV but the interior opulence of a flagship limousine.
In the 2026 landscape, the 2023 model holds a significant position as one of the final iterations of the "pre-facelift" Maybach GLS before the subtle 2024 updates. It retains a classic aesthetic that many collectors and luxury buyers prefer, characterized by the heavy use of pinstriped chrome and the iconic standing star on the hood—a feature reserved exclusively for the Maybach in the SUV lineup.
Powertrain and Mechanical Sophistication
Under the hood, the 2023 Maybach GLS 600 features a 4.0-liter V8 engine with twin turbochargers, meticulously tuned to produce 550 horsepower and 538 lb-ft of torque. This internal combustion engine is augmented by an integrated starter-generator (ISG), a 48-volt mild-hybrid system known as EQ Boost.
The Role of EQ Boost
The EQ Boost system serves multiple functions that enhance the luxury experience rather than just focusing on fuel efficiency. It provides an additional 21 horsepower and 184 lb-ft of torque for short bursts, ensuring that the heavy vehicle (weighing over 6,000 pounds) accelerates with effortless grace. More importantly, it allows for a seamless start-stop function. In a vehicle of this caliber, the vibration of an engine restarting at a traffic light would be an intrusion; the 48-volt system ensures the V8 fires up almost imperceptibly.
Driving Dynamics and the Maybach Mode
Power is delivered to all four wheels through the 9G-TRONIC 9-speed automatic transmission. However, the true technical highlight is the "Maybach" drive program. Unlike "Sport" or "Comfort" modes found in standard Mercedes vehicles, the Maybach mode is specifically calibrated for rear-seat passenger comfort. It flattens the acceleration curve, minimizes gear shifts to reduce "shift shock," and starts the vehicle in second gear to ensure the smoothest possible departure from a standstill.
The E-Active Body Control System
Perhaps the most significant technical achievement of the 2023 Maybach GLS 600 is its suspension. The E-Active Body Control is an optional (though frequently equipped) fully active hydropneumatic suspension powered by the 48-volt system.
- Road Surface Scan: Using a stereo camera, the system proactively "looks" at the road ahead. If it detects a pothole or speed bump, it adjusts the damping at each individual wheel before the tire even makes contact with the obstacle.
- Curve Tilting Function: In corners, the vehicle can lean into the turn like a motorcyclist. This reduces the lateral forces felt by passengers, preventing them from being slid across the leather seats during spirited driving or sharp highway exits.
- Free-Driving Mode: Often colloquially known as "Bounce Mode," this feature was originally designed to help the vehicle rock itself out of deep sand or snow by rapidly pumping the suspension. In the luxury market, however, it became a signature "party trick" that showcased the vehicle's hydraulic power.
Exterior Design and Presence
The exterior of the 2023 Maybach GLS 600 is designed to be immediately distinguishable from the standard GLS. The most prominent feature is the Maybach-specific grille, which features thin, vertical chrome slats inspired by a pinstriped suit.
Visual Cues and Finishes
The vehicle often features a two-tone paint scheme, a hallmark of the Maybach brand that requires a specialized hand-finishing process at the factory. The 23-inch forged multi-spoke wheels are another defining characteristic, designed to fill the wheel arches and provide a sense of substantiality.
Accessibility is managed by massive, electronically extending running boards. When a door is opened, the vehicle lowers itself via the air suspension, and a wide, anodized aluminum step slides out from under the side sill. This ensures that entry and exit remain dignified, regardless of the passenger's attire or physical mobility.
The Rear Cabin: A First-Class Suite
The interior is where the 2023 Maybach GLS 600 justifies its price tag. The standard configuration for this model is a four-seat layout, featuring the "Executive Rear Seat Package."
Reclining and Comfort
The two rear seats are not benches but individual "Captain’s Chairs" that can recline up to 43.5 degrees. They include powered calf rests, heated and cooled cup holders, and a massage function that utilizes "hot stone" technology. The upholstery is exclusive Nappa leather, covering almost every visible surface, including the dashboard, door panels, and even the headliner.
Amenities and Technology
Between the rear seats, owners can specify a refrigerated compartment designed to hold three bottles of champagne. Custom-made silver-plated champagne flutes are available as an accessory, featuring bases that clip into specially designed holders in the center console to prevent spilling while the vehicle is in motion.
Rear passengers also have access to the MBUX Rear Tablet, a 7-inch Samsung device that pops out of the center console. This tablet controls everything from the ambient lighting (which offers 64 colors) to the climate zones and the navigation system.

Practical Performance and Value in 2026
As we evaluate this vehicle from the perspective of 2026, the 2023 Maybach GLS 600 has entered a "sweet spot" in the pre-owned market. While new ultra-luxury SUVs suffer from significant initial depreciation, the 2023 model has largely stabilized.
Maintenance Considerations
Potential owners should be aware of the complexity of the 48-volt system. In 2026, as these vehicles move out of their original four-year warranty period, the maintenance of the E-Active Body Control system and the ISG becomes a primary consideration. These are highly sophisticated electronic components that require specialized diagnostic tools available primarily at authorized Mercedes-Benz centers.
Fuel Economy
According to the U.S. Environmental Protection Agency (EPA), the 2023 GLS 600 is rated at approximately 15 mpg city and 20 mpg highway. While fuel costs are rarely a primary concern for Maybach owners, the range of the vehicle is limited by these figures, necessitating more frequent stops on long-distance journeys compared to the newer electric Mercedes-Maybach EQS SUV.
Safety and Driver Assistance
Safety in the 2023 Maybach GLS 600 is handled by the "Driver Assistance Package Plus." This suite of tools is among the most advanced of its era, providing a bridge toward semi-autonomous driving.
- Active Distance Assist DISTRONIC: Maintains a set distance from the car ahead and can adjust speed based on upcoming curves or speed limits.
- Active Steering Assist: Helps keep the vehicle centered in its lane, even on slightly winding roads.
- Pre-Safe Impulse Side: If the vehicle detects an unavoidable side impact, it uses the seat bolsters to quickly move the occupant toward the center of the cabin, increasing the "crumple zone" between the passenger and the door.
- Safety Rating Context: While the Maybach variant is rarely crash-tested by the NHTSA due to its low volume, the standard GLS-Class, upon which it is based, consistently earns top marks for structural integrity.
Limitations and Suitability
The 2023 Maybach GLS 600 is not a universal solution for every luxury buyer. Its focus on the rear-seat experience means that the driver’s seat, while exceptionally comfortable, feels more like a "cockpit" for a professional chauffeur than a driver-centric environment.
Furthermore, the storage capacity is surprisingly limited for a full-size SUV. Because the rear seats are moved back to increase legroom and the refrigerator unit takes up significant space in the trunk, the cargo volume is much lower than that of a standard GLS. It is a vehicle designed for carrying people and their luxury weekend bags, not for utilitarian hauling or large family grocery runs.
Frequently Asked Questions
Is the 2023 Maybach GLS 600 bulletproof?
No, the standard 2023 Maybach GLS 600 is not armored or bulletproof. While Mercedes-Benz does have a "Guard" division that produces armored vehicles (like the S-Class Guard), the GLS 600 was not offered with factory-level armoring in 2023. Any armored versions found on the market are the result of third-party modifications.
How many seats does the 2023 Maybach GLS have?
It is available in two configurations. The most common is the four-seat layout with a fixed center console in the rear. However, a five-seat version was also manufactured, featuring a traditional three-person bench in the second row, though this version is rarer as it detracts from the "Maybach" experience.
Can the Maybach GLS 600 go off-road?
While it possesses an "Off-Road" drive mode and adjustable air suspension that can increase ground clearance, it is not an off-road vehicle. The 23-inch wheels and high-performance street tires are easily damaged by rocks or rough terrain. Its off-road capability is intended for navigating gravel driveways or snowy roads rather than technical trails.
What is the difference between a Maybach GLS and a standard GLS 600?
There is no "standard" Mercedes-Benz GLS 600. The "600" designation is exclusive to the Maybach brand. The highest-tier non-Maybach GLS is the AMG GLS 63, which focuses on performance and speed, whereas the Maybach GLS 600 focuses entirely on luxury and comfort.
Does the 2023 model have the MBUX Hyperscreen?
No, the 2023 Maybach GLS 600 features dual 12.3-inch displays (one for the instrument cluster and one for the infotainment). The "Hyperscreen," which covers the entire dashboard with glass, was introduced on electric models like the EQS and did not appear in the GLS-Class for the 2023 model year.
Final Recommendation: Should You Buy a 2023 Maybach SUV in 2026?
For those seeking the absolute peak of internal combustion luxury in an SUV format, the 2023 Mercedes-Maybach GLS 600 remains an exceptional choice. In 2026, it represents a more traditional luxury value compared to its newer electric counterparts, offering the visceral feel of a V8 engine and a design language that remains prestigious.
Next Actions for Buyers:
- Verify Service History: Ensure the 48-volt battery and E-Active Body Control system have been serviced according to manufacturer guidelines.
- Inspect the Leather: The Nappa leather in these vehicles is soft and prone to wear if not conditioned. Check the bolsters and the rear console.
- Test the Accessories: Ensure the MBUX tablet, refrigerator, and silver flutes (if included) are present and functional, as these are expensive to replace.
