Understanding the Mercedes-Benz GL Model Range

For many years, the “GL” designation in the Mercedes-Benz lineup represented their full-size, three-row luxury SUV. This vehicle was engineered to offer maximum space, comfort, and capability, embodying the brand’s commitment to luxury and innovation. While the nomenclature has evolved, the spirit of the GL lives on in its successors.

The GL model was designed to cater to families and individuals who needed ample passenger and cargo space without compromising on the premium driving experience Mercedes-Benz is known for. It combined the commanding presence of an SUV with the refinement of a luxury sedan, featuring high-quality materials, cutting-edge technology, and powerful yet smooth powertrains.

The Legacy: Original GL-Class (X164 and X166)

The original Mercedes-Benz GL-Class, designated by the chassis codes X164 (2006-2012) and X166 (2013-2019), established the benchmark for large luxury SUVs. These models were built to compete at the top of the segment, offering a blend of rugged capability and opulent comfort.

Key Characteristics of the Original GL-Class:

• Spacious Seating: Standard three-row seating accommodating up to seven passengers comfortably.
• Powerful Engines: A range of V6, V8, and even diesel engines provided strong performance and towing capability.
• Advanced Safety Systems: Early adoption of pioneering safety technologies like COLLISION PREVENTION ASSIST and ATTENTION ASSIST.
• Luxury Appointments: Premium leather upholstery, wood trim, and a sophisticated dashboard design.
• Off-Road Prowess: Available with 4MATIC all-wheel drive and often featuring an optional off-road package with skid plates and a two-speed transfer case for enhanced off-road capability.

The GL-Class was praised for its smooth ride, quiet cabin, and the sheer amount of space it offered. It was a true statement vehicle, designed for those who wanted the best in terms of capacity and luxury, whether for daily commutes or long-distance travel.

The Evolution: From GL to GLS

In 2016, Mercedes-Benz refreshed its SUV lineup nomenclature. The GL-Class was renamed the GLS-Class. This change aligned its naming convention with the rest of the Mercedes-Benz car range, with the “S” signifying its position as the flagship SUV, akin to the S-Class sedan. The X166 generation continued as the GLS until the arrival of a completely redesigned model in 2019 (X167).

The GLS continues the legacy of the GL, offering an even more refined and technologically advanced experience. It maintains the three-row, seven-seat configuration but elevates the luxury, performance, and technological features to new heights.

The Current GLS Model: The Pinnacle of Luxury SUVs

Today, when people refer to the “Mercedes GL model range” in the context of new vehicles, they are almost certainly referring to the Mercedes-Benz GLS. The current generation (X167, introduced for the 2020 model year) represents the zenith of Mercedes-Benz’s large SUV offerings, blending opulence with cutting-edge innovation. The GLS is designed to be a sanctuary on wheels, capable of comfortably transporting families and their luggage with effortless grace.

The 2024 Mercedes-Benz GLS Lineup

The current GLS lineup offers a variety of models, each providing a distinct blend of performance and luxury. The primary models typically include the GLS 450, GLS 580, and the high-performance AMG GLS 63.

Key Features That Define the GL/GLS Luxury

What truly sets the Mercedes-Benz GL and its successor, the GLS, apart is the consistent focus on a few core elements that define luxury and practicality in a large SUV. These features have been refined over generations to offer an unparalleled experience.

1. Uncompromising Space and Versatility

The defining characteristic of the GL/GLS is its generous interior volume. This isn’t just about fitting people; it’s about providing a first-class experience for every occupant.

Despite its size, the GL/GLS delivers a driving experience that rivals its sedan counterparts in terms of comfort and refinement.

• AIRMATIC Air Suspension: This standard system automatically adjusts ride height and suspension damping. It can lower the vehicle at higher speeds for better aerodynamics or raise it for increased ground clearance. It also isolates the cabin from road imperfections, creating a serene ride.

Owning a Mercedes-Benz GL or GLS is a rewarding experience, but like any luxury vehicle, it requires proper maintenance to ensure longevity and optimal performance. Understanding the maintenance schedule and potential considerations can help you keep your investment in top condition.

Routine Maintenance Schedule

Mercedes-Benz vehicles typically operate on a flexible service schedule, often noted as Service A and Service B. These services involve checks and replacements of vital fluids, filters, and components.

The exact schedule and services required can be displayed on the vehicle’s dashboard via the instrument cluster. It’s crucial not to ignore these service reminders. For detailed information tailored to your specific model year, consult your owner’s manual or the Mercedes-Benz maintenance guide. You can find comprehensive maintenance resources and recommendations on the Mercedes-Benz Service & Parts section of their website.

Common Areas to Monitor:

• Tires: Regular rotation and checking tire pressure are essential for even wear and optimal handling.
