2025 BMW X5 vs 2026 Mercedes-Benz GLS

The 2025 BMW X5 is the automaker’s midsize luxury SUV, positioned between the X3 and X7, and alongside the coupe-like X6. That puts it in a well-populated segment alongside SUVs like the Acura MDX, Audi Q7, Genesis GV80, Land Rover Range Rover Sport, Lexus RX, Mercedes-Benz GLE-Class, Porsche Cayenne, and Volvo XC90. Following a substantial update for the 2024 model year, the X5 celebrates its 25th anniversary with a limited-edition model, but receives no other changes.

Verdict: The latest version of the X5 isn’t the best value, but it explains this SUV’s longevity.

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.
