Comparison Overview

Deciding between the 2026 Acura RDX and the 2026 Toyota Highlander often boils down to whether you prioritize spirited driving dynamics or absolute maximum capacity. Both crossovers start near the $45,000 mark, but they diverge quickly in execution. The RDX packs a punch with 272 horsepower and 280 lb-ft of torque, offering slightly more power in a smaller footprint (187.4 inches long). However, the Highlander compensates with sheer volume, offering substantially more cargo space at 16 cu ft compared to the RDX’s 29.5 cu ft—wait, checking the specs again, the RDX actually shows 29.5 cu ft and the Highlander shows 16 cu ft. That is a massive point of differentiation! Furthermore, the RDX recommends premium fuel while the Highlander happily runs on regular unleaded, saving a few cents per fill-up. While both offer AWD, the RDX boasts a 10-speed automatic transmission versus the Highlander’s 8-speed.
