Mercedes-Benz GL-Class – Where Luxury Leads the Way

The Mercedes-Benz GLS-Class is a full-size luxury SUV originally introduced as the GL-Class in 2006. Manufactured first by DaimlerChrysler and later by Daimler AG, it features a 5-door, 7-seater configuration with a front-engine, all-wheel-drive (4MATIC) layout. Positioned above the GLE-Class, it serves as the flagship SUV in the Mercedes-Benz lineup, sharing a similar unibody construction. Since 2016, it has been renamed the GLS-Class. This article focuses on the first two generations—X164 and X166—highlighting their performance, comfort, and safety.

The First Generation: X164

Produced between 2006 and 2012, the X164 marked the debut of the GL-Class. Built as a full-size luxury SUV, it shared its platform with the ML-Class and came equipped with a 7-speed 7G-Tronic automatic transmission. Buyers could choose from a range of petrol and diesel engines, offering both performance and efficiency.

Engines

The petrol lineup included the GL450 and GL500. The GL450 produced 335 hp, while the GL500 delivered 382 hp, both offering strong performance for a vehicle of its size. On the diesel side, options included the GL320 CDI, GL350 CDI, GL350 CDI Bluetec, and the more powerful GL420 and GL450 CDI models. These engines ranged from 181 hp to 302 hp, with impressive torque figures that enhanced towing and off-road capability.

Interior

The X164 provided a spacious and luxurious cabin designed to comfortably seat up to seven passengers. It featured 8-way power-adjustable front seats with memory function and flexible seating arrangements that allowed for increased cargo space. A fixed-glass sunroof enhanced the cabin ambiance by letting in natural light while reducing heat.
Technology was also a highlight, with steering-wheel-mounted controls for convenience. Entertainment options included a 6-DVD/CD changer, SiriusXM satellite radio, iPod integration, and a 4GB music storage system—delivering a premium in-car experience.

Safety & Security

Safety was a major focus, with features such as Bi-Xenon headlamps, LED daytime running lights, and Blind Spot Assist. The PRE-SAFE system prepared the vehicle in case of instability, while Electronic Stability Program (ESP) and Brake Assist improved control. With nine airbags offering extensive protection and a post-collision response system, the X164 set a high standard in SUV safety.

The Second Generation: X166
Introduced in 2013 and produced until 2019, the X166 brought significant improvements in design, performance, and technology. It offered four engine variants paired with either a 7-speed or 9-speed automatic transmission.
Engine
The petrol lineup included the GL350, GL450, GL550, and the high-performance GL63 AMG. Power outputs ranged from 329 hp to an impressive 577 hp in the AMG variant. These engines delivered enhanced acceleration and smoother performance, making the SUV both powerful and refined.
Interior
The second generation elevated comfort with a more advanced and spacious interior. The EASY-ENTRY feature allowed convenient access to rear seats, while foldable second and third rows provided flexible cargo space—up to nearly 50 cubic feet.
Entertainment was upgraded with a rear-seat system featuring dual screens, wireless remotes, and headsets, allowing passengers to enjoy movies or games on the go. Additionally, the Surround View System used multiple cameras to create a bird’s-eye view, improving parking and maneuvering.
Safety and Security
The X166 introduced advanced driver assistance systems, including Distronic Plus adaptive cruise control with PRE-SAFE Brake. PARKTRONIC with Active Parking Assist enabled semi-automated parking, while Crosswind Assist improved stability in strong winds.
