With the transition to the GLS-Class in 2017, Mercedes-Benz subtly refined the exterior. The goal was to align it more closely with the brand’s then-current design language. This meant a slightly more sculpted hood, updated grille designs, and revised front and rear bumper treatments. The overall proportions remained similar, emphasizing the vehicle’s substantial footprint and commanding road presence. The latest models continue this tradition, with sharper lines and more integrated lighting, reflecting Mercedes-Benz’s evolving design philosophy.

A Sanctuary on Wheels

Step inside any GL or GLS model from 2016 onwards, and you are immediately enveloped in a world of luxury and meticulous craftsmanship. The interiors are spacious, designed to comfortably accommodate up to seven passengers across three rows. This makes it an ideal choice for larger families or for those who frequently transport guests.

The materials used are consistently premium. Expect to find high-quality leather upholstery, real wood trim, and soft-touch surfaces throughout the cabin. The ergonomics are superb, with controls placed intuitively, and the overall layout is designed to minimize driver distraction while maximizing comfort.

Key Interior Features to Expect Across Generations:
