2026 Mercedes-Benz GLS vs 2026 Land Rover Range Rover Sport

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.

A base-model Range Rover Sport costs about the same as a mid-tier trim of any other midsize luxury SUV. Land Rover plays in the big leagues, which require a minimum of $85,000 or a lease payment approaching $2,000 per month. Even with such immense outlays, the Range Rover Sport is Land Rover's second most-popular model in the U.S. and far surpasses the Velar, the Evoque, and the Discovery. This is the lens from which we evaluate the Range Rover Sport. The particular 2026 model we tested—the SV Carbon—is also the fastest, most extreme vehicle the company has ever made, providing further context for its roughly $200,000 MSRP. At that price, the choices narrow to a new Porsche Cayenne Turbo, or a lightly-used Aston Martin DBX or Lamborghini Urus.

Verdict: Anywhere it goes, the Range Rover Sport is at the top of its class.
