Lexus RX Hybrid vs Mercedes-Benz GLS

Buyers have high expectations of luxury crossovers. They want arresting design, comfortable interiors, the latest technology, and powerful engines. Several automakers employ turbocharged six-cylinder engines to get that power, but Lexus is going a different way with its most potent RX model—the RX 500h F Sport Performance. It still uses a turbocharger, but also employs hybrid technology to boost power and cut acceleration times while improving fuel economy. It’s one of two 2026 Lexus RX Hybrid models, along with the tamer RX 350h.

Verdict: The RX 500h F Sport Performance may be the most powerful RX, but it’s not as powerful or quick as most rivals, and despite the F Sport badge, there isn’t much real “sport” to be had. While it does have good EPA fuel economy ratings, we found them hard to match in the real world.

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.
