2025 Acura RDX vs 2026 Mercedes-Benz GLS

Although the current-generation RDX is seven years old, it remains as appealing as ever. Subtle styling, wheel, and paint color updates freshen the compact crossover SUV’s appearance. Acura also upgrades the center console with a new wireless charging pad, and revised cupholders now effortlessly hold a 32-ounce Hydro Flask bottle. This model year, the top A-Spec Advance trim adds full leather upholstery, and Acura introduces an improved presentation of Apple CarPlay and Android Auto.

Verdict: Though the current-generation RDX hasn’t seen a redesign since the 2019 model year, it remains an appealing choice and a genuine bargain in the compact luxury crossover SUV segment. This Acura’s most glaring flaws pertain to its infotainment system interface and thirsty engine.

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.
