2027 Mercedes-Benz GLS vs 2026 Lexus GX

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.

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.
