2027 Mercedes-Benz GLS vs 2026 Mercedes-Benz GLS

It could be said that the Mercedes GLS is the S-Class of SUVs, but that’s not entirely accurate. The S-Class sedan commands a significant premium over the GLS, while the legendary G-Class SUV is even more expensive than the S-Class. Nevertheless, for buyers who want a three-row SUV with a three-pointed star on its grille, the 2026 Mercedes-Benz GLS is the right choice because it offers more passenger room and cargo space than any other model in the automaker’s lineup.

Verdict: Large, luxury SUVs are a lot more expensive than they used to be, and while the 2026 Mercedes GLS can’t match them for sheer size and capability, its manageable dimensions, undeniable comfort, refinement, and rewarding driving dynamics make a strong case.

The full-size, three-row GLS is for anyone who needs extra space and towing capacity in their luxury SUV. Mercedes also considers the GLS to be the SUV equivalent of its flagship S-Class sedan, so it can be equipped with virtually every feature in the automaker’s catalog. For 2027, the GLS receives updated styling, powertrains, and tech features. Its competition includes the BMW X7, the Cadillac Escalade, the Land Rover Range Rover, the Lexus LX, the Lincoln Navigator, and the all-new Audi Q9.

Verdict: The extensive updates don’t make as much difference as expected from behind the wheel, but that’s okay because the GLS was already a well-executed luxury SUV.
