2025 Lexus RX Hybrid vs 2026 Mercedes-Benz GLS

In 2024, the Lexus RX was the best-selling traditional luxury model in America. But is the midsize, two-row SUV’s popularity justifiable? Or does the RX sell on the strength of the Lexus brand and the model’s legendary reputation for reliability, a plush ride, and a quiet interior? The changes to the 2025 RX don’t help answer that question, unless you're looking for sportier choices, such as the new Black Line Special Edition shown here.

Verdict: Though it lacks substantial competition in the luxury hybrid SUV segment, the 2025 Lexus RX Hybrid is worthy of consideration. With hybrid, performance hybrid, and plug-in hybrid (PHEV) powertrain choices, as well as a range of trim levels that cater to a variety of customer requirements, it checks a lot of boxes.

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.
