2026 Acura RDX vs 2026 Subaru Ascent

$45,100 · Crossover

$40,795 · Crossover

Comparison Overview

Trying to decide between a sharp, slightly sportier luxury crossover and a larger, more practical family hauler often boils down to budget versus premium feel. The 2026 Acura RDX starts at $45,100, positioned noticeably higher than the 2026 Subaru Ascent's $40,795 starting price—a difference of $4,305 right off the lot. Performance favors the Acura slightly; the RDX offers 272 hp compared to the Ascent's 260 hp, though both deliver similar torque figures around 280 lb-ft. Fuel economy is quite close, with the RDX achieving 23 MPG combined versus the Ascent's 22 MPG combined, but the Acura recommends premium fuel. Size differences matter too: the Ascent is considerably longer at 196.8 inches versus the RDX's 187.4 inches, which likely translates into greater interior volume despite the RDX showing more dedicated cargo space at 29.5 cu ft versus the Ascent’s 17.8 cu ft (this difference strongly suggests the Ascent uses its extra length for a third row).
