2026 Mercedes-Benz GLS vs 2026 Lexus GX

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 Lexus GX midsize SUV seats up to seven people, tows just over 9,000 pounds when properly equipped, can hold more than 90 cubic feet of cargo, and easily travels where few vehicles dare to tread. The 2026 GX 550 comes in Premium, Premium+, Overtrail, Overtrail+, Luxury, and Luxury+ trim levels, each equipped with a twin-turbocharged V6 engine and standard four-wheel drive (4WD). Lexus reported no changes to this SUV for the 2026 model year.

Verdict: Poor fuel economy aside, the GX is a good luxury SUV designed for serious off-roading and towing. For those who require neither, the Lexus RX is a better pick.
