Why it stands out

The 2025 Mercedes-Benz GLS stands out as the roomiest vehicle in the Mercedes-Benz lineup, with three rows of seating for six or seven people and up to 94 cubic feet of cargo space. That combination makes it a strong fit for buyers who want full-size family utility without giving up the brand’s emphasis on comfort and luxury. It is also described as a midsize SUV that blends the comfort and space of the S-Class luxury sedan with a modicum of off-road capability from the G-Class, which helps explain its broad appeal.

For 2025, the GLS also benefits from the second generation’s emphasis on technology and convenience. Standard equipment includes dual 12.3-inch displays with MBUX, navigation, a Burmester surround sound stereo, SiriusXM, nine USB-C ports, wireless charging, three years of Mercedes Me Connect services, heated front seats, MB-Tex upholstery, a sunroof, power-folding third-row seats, power-adjustable second-row seats, and 19-inch wheels. The model also includes a practical seating function that automatically adjusts the seat in front when a second- or third-row seat is folded, making it easier to manage cargo and passenger space in a large SUV.

There are some tradeoffs, though. The GLS is not the tallest, the longest, or the most expensive Mercedes, and the buying guide notes that third-row seat access and touch-sensing controls are drawbacks. Even so, the 2025 GLS remains appealing for shoppers who want a spacious, upscale three-row SUV with a strong mix of comfort, technology, and everyday usefulness.
