2026 Mercedes-Benz GLS vs 2025 Chevrolet Suburban

The Chevy Suburban sees significant updates for the 2025 model year, but the most impactful are visible only from the inside. A new touchscreen interface joins a flashy driver information display, and together they solve one of our biggest gripes with the outgoing model. Beyond its tech update, the new Suburban features a refreshed exterior, new interior upgrades, and a revised diesel engine that is now available on the Z71 trim level.

Verdict: Z71 shoppers will love the newly available 3.0-litre diesel, but the majority of shoppers are going to want a new 2025 Suburban because of its impressive 17.7-inch touchscreen display.

It could be said that the Mercedes-Benz 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. 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. While the 2026 Mercedes-Benz GLS can’t match them for sheer size and capability, its manageable dimensions, undeniable comfort, refinement, and rewarding driving dynamics make a strong case.
