The Plug-In Hybrid (PHEV) variant is consistently praised for its exceptional all-electric range (frequently cited as best-in-class at the time), refined and quiet cabin, comfortable ride quality attributed to a sophisticated multi-link rear suspension, and high-quality interior materials that exceed typical Honda expectations, offering an Acura-like feel. Owners report high satisfaction with the ability to conduct daily commutes entirely on electricity while having a gasoline engine for longer trips.
