Mercedes-Maybach GLS 600: Definitive Luxury SUV Review

The Mercedes-Maybach GLS 600 elevates the full-size SUV category to new heights of sophistication and indulgence. Building on the robust foundation of the standard GLS, this Maybach variant introduces unparalleled levels of comfort, advanced engineering, and bespoke detailing designed for those who demand the absolute best in personal transport. Whether navigating urban streets or embarking on long-distance journeys, the GLS 600 delivers a driving experience that feels more like gliding in a private jet than piloting an SUV.

Design and Exterior Presence

From the outset, the Mercedes-Maybach GLS 600 commands attention with its imposing yet elegant stance. Measuring over five meters in length, it boasts a longer wheelbase than its standard sibling, contributing to enhanced interior space and a smoother ride. The exterior features a distinctive chrome-heavy front grille emblazoned with the prominent Maybach double-M emblem, flanked by sleek LED headlights that provide exceptional illumination. Sleek lines and aerodynamic shaping minimize wind noise, ensuring a hushed cabin even at highway speeds.

The bodywork is adorned with polished chrome accents along the sides, window lines, and exhaust tips, underscoring its premium positioning. Large 22-inch or optional 23-inch alloy wheels fill the arches, wrapped in low-profile tires that balance aesthetics with performance. Available in a range of exclusive paint finishes, including diamond white metallic, the GLS 600 exudes an air of exclusivity rivaling high-end sedans like the S-Class.

• Key exterior highlights: Extended wheelbase for superior proportions, illuminated Maybach grille, adaptive LED lighting, and multiple chrome trims.
• Wheel options enhance both style and handling precision.

Powertrain and Performance Capabilities

At the heart of the Maybach GLS 600 lies a handcrafted 4.0-liter twin-turbo V8 engine, producing 550 horsepower and a substantial 538 lb-ft of torque. This powerhouse is augmented by a 48-volt mild-hybrid system, known as EQ Boost, which delivers an additional 21 horsepower and 184 lb-ft of torque for seamless low-speed acceleration and efficient stop-start operation. Paired with a nine-speed automatic transmission and standard 4Matic all-wheel drive, power is distributed effortlessly to all four wheels.

Performance figures are impressive for a vehicle weighing around 5,500 pounds: 0-60 mph in approximately 4.9 seconds, with a top speed electronically limited to 155 mph. The drivetrain shines in everyday scenarios, offering refined power delivery whether merging onto freeways or tackling inclines. Off-road, the adjustable air suspension and low-range transfer case enable light adventure capabilities, though this SUV is primarily engineered for paved perfection.

This table illustrates how the Maybach’s V8 elevates performance over the base GLS 450’s inline-six, albeit at the cost of fuel efficiency.

Chassis Dynamics and Ride Quality

Mercedes-Benz equips the GLS 600 with an advanced air suspension system as standard, featuring adaptive damping that adjusts in real-time to road conditions. Optional E-Active Body Control takes this further, using a 48-volt starter-generator to individually control each wheel’s movement. This hydraulic setup scans the road ahead with cameras and sensors, preemptively countering imperfections like potholes by lifting the affected wheel—effectively making bumps vanish.

Handling belies the vehicle’s size; the long wheelbase and precise steering provide stability at high speeds, while multiple drive modes (Comfort, Sport, Sport+, Off-Road) allow tailoring to preferences. In Comfort mode, the ride is buttery smooth, isolating occupants from road harshness. Sport mode firms up the setup for more engaging dynamics without sacrificing poise. Reviewers note its ability to corner flat and maintain composure, rivaling smaller luxury sedans.

Interior Opulence and Space

Step inside the Maybach GLS 600, and you’re enveloped in a sanctuary of luxury. The cabin employs Nappa leather across nearly every surface, with intricate quilted patterns and open-pore wood veneers. Dual 12.3-inch digital displays form a seamless widescreen cockpit, controlled via touchpads, voice commands, or the intuitive MBUX infotainment system. Crystal controls and backlit buttons add tactile delight.

Seating for up to seven includes power-adjustable, heated, and ventilated front thrones with massage functions mimicking hot stones. The second row features captain’s chairs with extensive recline, ottomans, and active multicontour support—transforming it into a first-class lounge. Third-row access is improved via sliding second-row seats, though space back there suits children or shorter adults best. A panoramic sunroof floods the space with light, complemented by ambient lighting with 64 colors.

• Premium audio: Burmester 3D surround sound with up to 26 speakers.
• Climate control: Four-zone automatic with rear blinds and ionized air purification.
• Storage: Ample compartments, fridge console option, and folding tables.

The executive rear seat package enhances long-haul comfort, making it ideal for chauffeured drives.

Technology and Driver Assistance Suite

The MBUX system powers crisp navigation, augmented reality views, and voice-activated controls via “Hey Mercedes.” Adaptive cruise control with stop-and-go, lane centering, and automatic speed adjustment based on limits form the core of the safety package. However, some users report occasional quirks, like overzealous interventions.

Additional aids include blind-spot monitoring, evasive steering assist, and a 360-degree camera. Parking is effortless thanks to Active Parking Assist, which can autonomously maneuver into spaces.

Pricing and Ownership Considerations

Starting at around $175,000, the GLS 600’s price escalates quickly with options. A fully loaded example can exceed $200,000. Maintenance costs are premium, but the seven-year powertrain warranty and complimentary service periods mitigate this. Fuel economy lags at 14/19 mpg, reflecting its thirst.

Competitors like the Rolls-Royce Cullinan or Bentley Bentayga command higher prices but offer similar exclusivity. The GLS 600 excels in value for tech-forward luxury.
