2027 Mercedes-Benz GLS vs 2026 BMW X5

Five versions of this midsize luxury SUV are available for 2026, all satisfying in one way or another. The 40i models cost the least but can be optioned with almost everything buyers could want. The 50e is a plug-in hybrid with 38 miles of electric-only range. The M60i and X5 M are the performance models, and offer a handful of desirable exclusive options, especially for audiophiles with deep pockets.

Verdict: Prices rise quickly with upgrades, but few luxury SUVs blend style, quality, comfort, tech, and performance like the 2026 X5.

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.
