Honda Clarity 2017–2021 car dimensions: 4895 mm long, 1877 mm wide and 1478 mm high. Unladen weight is 1,838 kg. Boot space with the seats up is 439 litres.
The cabin seats five with dual-zone automatic climate control and heated front seats standard. An 8-inch touchscreen supports Apple CarPlay and Android Auto. Honda Sensing is standard across the board and includes adaptive cruise control with low-speed follow, collision mitigation braking, lane keeping assist, road departure mitigation, and multi-angle rearview camera with dynamic guidelines. Honda LaneWatch provides a passenger-side blind-spot camera view.
Trunk volume is 439 litres with the 60/40 split-folding rear seats up. The battery pack sits under the floor so the trunk remains a full-size sedan space that can hold multiple large bags.
The vehicle is not designed to tow a trailer. Payload is approximately 414 kg based on the difference between GVWR and curb weight. No heavy-duty cooling or reinforced suspension packages are listed.
The cabin feels quiet and refined thanks to acoustic glass on the windshield and front doors plus active noise cancellation. Heated front seats come standard on both trims, with soft cushions that support well on long drives. Base models use bio-fabric trim while Touring adds perforated leather, an 8-way power driver seat with memory, and 4-way power passenger seat. Dual-zone climate control keeps the five-passenger space comfortable, though rear legroom is tighter than some rivals and the low seat mounts reduce thigh support. No sunroof appears due to the body structure.

The plug-in hybrid returns 42 mpg combined on gasoline alone and 110 MPGe when using both power sources. Electric-only range reaches 47 to 48 miles, enough for most daily trips before the 1.5-liter engine joins in. Total driving range hits about 340 miles on a full charge and tank of regular unleaded. A Level 2 charger fills the 17 kWh battery in roughly 2.5 hours.
Honda’s Maintenance Minder tracks oil life and other needs based on actual use rather than fixed miles. Oil and filter changes typically fall between 7,500 and 10,000 miles under normal conditions. The engine is designed for 100,000-mile tune-up intervals with only fluid and filter services in between. Battery warranty runs eight years or 100,000 miles.
Every Clarity carries the full Honda Sensing package including collision mitigation braking, adaptive cruise with low-speed follow, lane keeping assist, and road departure mitigation. A multi-angle rearview camera, LaneWatch, stability control, and a full set of airbags including a driver knee bag are also standard. The ACE body structure and high-strength steel help manage crash energy, though neither NHTSA nor IIHS published ratings for this model.
Living with the car means plugging in regularly for best efficiency and watching the Maintenance Minder display for service cues. The quiet cabin and cushy ride make daily use easy, while the 15.5 cubic-foot trunk and 60/40 split rear seats handle grocery runs or weekend gear without drama.
