INTRODUCTION
The Mercedes-Maybach GLS 600 (X167, facelift 2023) is a full-size luxury SUV that represents the highest echelon of the GLS model range. Introduced in September 2023, this facelifted version builds upon the foundation laid by the original Maybach GLS, offering enhanced refinement, technology, and exclusivity. It’s positioned above even the standard Mercedes-Benz GLS, catering to a clientele seeking an unparalleled level of comfort and prestige. The vehicle is built on the MHI platform (Modular High-volume Architecture) and shares its core structure with other Mercedes-Benz SUVs, but receives extensive Maybach-specific modifications.
Powertrain & Engine Architecture
At the heart of the GLS 600 lies the M177.980 4.0-liter V8 engine, a twin-turbocharged masterpiece. This engine benefits from a 48-volt mild-hybrid system (MHEV), incorporating a belt-driven starter-generator (RSG) that enables functions like gliding, boosting, and energy recovery. The engine produces 557 horsepower at 6000-6500 rpm and a substantial 730 Nm (538 lb-ft) of torque between 2500-5000 rpm. Direct fuel injection and a sophisticated engine management system optimize combustion efficiency and power delivery. The 9G-TRONIC nine-speed automatic transmission is standard, meticulously calibrated to provide smooth and responsive shifts. The transmission’s gear ratios are tuned for both effortless cruising and brisk acceleration. The mild-hybrid system doesn’t provide electric-only driving, but it significantly improves fuel economy and reduces emissions.
Driving Characteristics
The GLS 600 delivers a driving experience that prioritizes comfort and effortless power. The 4.7-second 0-60 mph acceleration is impressive for a vehicle of this size and weight. The 9G-TRONIC transmission contributes to a seamless driving experience, with well-spaced gear ratios that keep the engine in its optimal power band. While not as overtly sporty as some performance SUVs, the GLS 600 offers ample power for confident overtaking and highway cruising. The air suspension, standard equipment, provides a remarkably smooth ride, absorbing bumps and imperfections with ease. The 4MATIC all-wheel-drive system ensures confident traction in all weather conditions.
Equipment & Trim Levels
The Maybach GLS 600 is exceptionally well-equipped as standard. Key features include exclusive Maybach leather upholstery, ventilated and massaging front and rear seats, a premium Burmester surround sound system, and a panoramic sunroof. The rear compartment is particularly lavish, featuring two individual executive seats with extensive adjustability and a dedicated entertainment system. Optional extras include a champagne cooler, bespoke interior trim options, and a variety of driver-assistance systems. The interior is characterized by its high-quality materials, meticulous craftsmanship, and attention to detail.
Chassis & Braking
The GLS 600 utilizes an air suspension system with adaptive damping control (AIRMATIC). This system allows the ride height to be adjusted, providing increased ground clearance for off-road driving or a lower stance for improved aerodynamics. The suspension is tuned for maximum comfort, but also offers a degree of body control in corners. The braking system features ventilated discs on all four wheels, providing ample stopping power. Advanced driver-assistance systems, such as automatic emergency braking and lane-keeping assist, are standard.
Market Reception & Comparison
The Mercedes-Maybach GLS 600 has been well-received by critics and consumers alike, praised for its luxurious interior, powerful engine, and refined driving experience. Compared to the standard GLS, the Maybach variant offers a significantly more opulent and exclusive experience. While fuel economy is not a strong point (13.9-14.2 l/100 km), it’s comparable to other vehicles in its class. Reliability has been generally good, although the complexity of the vehicle’s systems means that maintenance costs can be higher than those of more mainstream SUVs.
Legacy
The Mercedes-Maybach GLS 600 represents a significant step forward in the luxury SUV segment. Its combination of power, comfort, and exclusivity has established it as a benchmark for its competitors. The mild-hybrid powertrain demonstrates Mercedes-Benz’s commitment to improving fuel efficiency and reducing emissions. On the used car market, the GLS 600 is expected to hold its value well, appealing to buyers who appreciate its unique blend of luxury and performance. The vehicle’s sophisticated technology and high-quality construction suggest that it will provide years of reliable service with proper maintenance.
