INFINITI QX80 vs Mercedes-Benz GLS

The traditional body-on-frame SUV is rarely a wise choice these days. These vehicles are heavy and inefficient, but they can be the right option for buyers who need to carry lots of passengers and either tow trailers or go off-roading. The 2026 Infiniti QX80 carries up to seven people and can tow up to 8,500 pounds, while also adding luxury and some thoughtful features that help it stand out against competitors such as the Cadillac Escalade and the Lincoln Navigator. Redesigned for the 2025 model year, the 2026 QX80 is unchanged except for a new Sport trim level.

Verdict: The 2026 Infiniti QX80 appeals for luxury, space, technology, and towing capacity, but poor fuel economy and cumbersome handling mean more nimble crossover SUVs are better for most families.

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.
