Why it stands out

The 2026 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 2,400 litres of cargo space. It is also positioned as a midsize SUV that blends the comfort and space of the S-Class luxury sedan with some off-road capability from the G-Class. For 2026, the GLS 450 starts at $132,744, the GLS 580 starts at $165,144, and the AMG GLS 63 starts at $226,256.

What makes the 2026 GLS especially distinctive is how much equipment it brings to the table. Standard features include heated front seats, MB-Tex upholstery, a sunroof, dual 12.3-inch displays with MBUX touchscreen functionality, navigation, a Burmester surround sound stereo, SiriusXM, nine USB-C ports, wireless charging, three years of Mercedes Me Connect services, power-folding third-row seats, power-adjustable second-row seats, and 19-inch wheels. It also includes safety and convenience features such as blind spot assist, 360-degree cameras, adaptive headlamps, auto high beams, parking assist, Car-to-X communication, and Exit Warning Assist.

The GLS also has a practical seating trick that automatically adjusts the seat in front when part of the second or third row is folded, making it easier to load passengers and cargo. Buyers looking for more luxury can find available touches such as heated armrests, massaging and cooling second-row seats, heated third-row seats, a head-up display, a 25-speaker stereo, extra window insulation, and semi-automated driving. At the same time, the GLS is not without drawbacks: the AMG Line Package can impede entry and exit, third-row access is a challenge, and touch-sensing controls remain a weak point.
