2026 Acura RDX vs. 2025 Cadillac XT6

Car Chomper says a 37-horsepower advantage means the 2026 Acura RDX, at 272 hp, should feel noticeably quicker and more responsive during acceleration than the 2025 Cadillac XT6's 235-hp engine, and the RDX is the undisputed champion for hauling large items, offering 29.5 cubic feet of cargo space, more than double the XT6's 12.6-cubic-foot capacity, with the RDX's standard all-wheel drive offering better all-weather traction than the XT6's front-wheel-drive configuration, though both report identical fuel-economy ratings at 23 mpg combined. TrueCar confirms the RDX's $46,650 starting price undercuts the XT6's $50,690 by $4,040, a gap TrueCar says holds at the real-world average prices buyers actually pay.
