The short answer
Based on available data, the Honda Clarity comes out ahead of the Chevrolet Volt on fuel economy and power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Mixed to highly positive sentiment, heavily dependent on model year and specific ownership experience. The vehicle is widely praised for its innovative plug-in hybrid design, offering substantial all-electric range (reported 40-60 miles for Gen 2, 35-43 miles for Gen 1) for daily commuting, with a gasoline range extender eliminating long-distance anxiety. Owners frequently describe it as a practical, low-cost commuter with minimal fuel consumption (reports of 1.5L/100km or ~8000 miles on a single 9-gallon tank are cited) and extremely low maintenance requirements when operating primarily on electricity.
Best version to buy
Gen 2 (2016-2019) Premier/LTZ trim. This generation is noted for its improved electric range (53 miles EPA), more refined infotainment system with available Android Auto/Apple CarPlay (after software update), and generally better interior materials.

Overall
Mixed sentiment with a strong positive bias among long-term owners who appreciate the vehicle's core value proposition. 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.

The Plug-In Hybrid (PHEV) variant is overwhelmingly the version discussed and recommended by owners. The Fuel Cell (FCV) and Battery Electric (BEV) variants are mentioned only in the context of the model's history and discontinuation, with no substantive owner feedback provided in the data.
