Exterior Design: A Commandingly Elegant Presence

The Mercedes-Benz GL-Class, and its successor the GLS-Class, has always been about making a statement. Even from its earlier iterations, the design philosophy has centered on a powerful, yet refined, presence. The 2017 model year, as the first GLS, brought a noticeable update that transitioned the vehicle into Mercedes-Benz’s contemporary design language.

Key Exterior Elements of the 2017-2024 GLS-Class:

• Dominating Grille: Typically featuring the prominent Mercedes-Benz star at the center, flanked by bold chrome louvers. This design element immediately signals its luxury status.

Step inside a GL-Class or GLS-Class, and you’re immediately immersed in a world of refined luxury and thoughtful design. This is where the “ultimate luxury” promise truly comes to life, offering a spacious and comfortable environment for up to seven passengers, along with their luggage.

What to Expect Inside:

• Premium Materials: Expect high-quality leather upholstery, real wood or metal trim, and soft-touch surfaces throughout the cabin. The attention to detail in material selection and fit-and-finish is a hallmark of this vehicle.
• Spacious Seating: The first and second rows offer generous legroom and headroom. The third row, while often best suited for children or shorter journeys, is still more accommodating than in many smaller SUVs, especially in the GLS variants which have been optimized for space.
• Comfort Features: Multi-way power-adjustable front seats, often with heating, ventilation, and massage functions, ensure maximum comfort for the driver and front passenger.
• Climate Control: Multi-zone automatic climate control systems maintain a perfect cabin temperature for everyone.
• Ample Cargo Space: With the third-row seats folded, the cargo area is cavernous, capable of swallowing large shopping hauls or gear for a family road trip. The power-folding third row (standard on many models and years) makes expanding cargo space incredibly convenient.
• Quiet Cabin: Extensive sound deadening and acoustic glass create a remarkably quiet interior, allowing for relaxed conversations or enjoying the premium audio system.

The 2017 GLS built upon the GL’s foundation with updated dashboard and console designs, often featuring a larger central screen. Newer models, particularly the redesigned generation introduced for the 2020 model year, further elevate the interior with the brand’s latest MBUX infotainment system, dual 12.3-inch screens (one for the instrument cluster, one for the central display), and even more sophisticated ambient lighting options.

Performance and Powertrain: Power Meets Poise

The GL/GLS-Class is engineered to move its considerable mass with effortless grace. The powertrain options have always been focused on delivering robust performance, whether for everyday driving, confident towing, or spirited acceleration.

For those interested in weight and dimensions, these large SUVs are substantial. For instance, a 2017 GLS 450 has a curb weight of around 5,400 lbs. Understanding these specifications can be helpful for towing and general vehicle comprehension. You can find detailed specifications for individual models on certified automotive sites or the manufacturer’s archives.

Cutting-Edge Technology and Infotainment

Mercedes-Benz is at the forefront of automotive technology, and the GL/GLS-Class consistently reflects this. Whether you are looking at a 2017 model or a brand-new 2024 version, you can expect a suite of features designed to enhance convenience, safety, and entertainment.

COMAND and MBUX Systems:

• COMAND (Cockpit Management and Navigation): Found in the 2017 and earlier models, this system typically features a central display controlled via a rotary dial and buttons on the center console, along with steering wheel controls. It integrates navigation, audio, Bluetooth, and vehicle settings.
• MBUX (Mercedes-Benz User Experience): Introduced in newer generations (from 2020 onwards), MBUX is a significant leap forward. It features a dual-screen setup with a highly intuitive touch interface, advanced voice control (“Hey Mercedes”), and augmented reality navigation.

Key Technology Features:

• Navigation: Advanced GPS navigation systems, often capable of over-the-air updates, guide you to your destination with ease.
