Comparison Overview

Trying to decide between sleek German refinement and practical Japanese versatility? That's the common tight spot pitting the 2025 Audi A4 allroad against the 2026 Acura RDX. Performance figures are surprisingly close: the RDX squeaks ahead with 272 hp versus the Audi's 261 hp, matched by slightly more torque (280 lb-ft vs. 273 lb-ft). However, the A4 allroad delivers better fuel efficiency, netting 26 combined MPG compared to the RDX's 23 combined MPG, thanks partly to its smaller frame (187.5 inches long vs. the RDX at 187.4 inches). Cargo space is a significant differentiator, with the RDX offering a practical 29.5 cu ft against the Audi's 24.2 cu ft. You’ll also notice the RDX is significantly taller at 65.7 inches, providing that traditional SUV sightline over the lower-slung Audi wagon.
