Sources & notes

This record describes the stated 2021 U.S. configuration only; it does not represent every trim or model year in the generation.
Millimeters are converted from the cited U.S. manufacturer inch measurements using 25.4 mm per inch and rounded to the nearest millimeter.
XLE configuration: 182 hp traction motor, 4,255 lb curb weight and 402-mile EPA range. Limited efficiency, range and curb weight are not applied to XLE.
Hydrogen fuel generates electricity on board. MPGe is gasoline-equivalent efficiency, not gasoline MPG; EPA range is on a full hydrogen fill, not a plug-in battery charge.
EPA classifies the transmission as automatic. No physical gear count or CVT mechanism is inferred from its variable-gear-ratio database label.
Mirror inclusion in overall width is not explicit in the cited source and remains unverified.
Hydrogen tank internal volume is not entered as a gasoline fuel-tank capacity. Buffer battery capacity is not represented as a plug-in battery. Unverified values are absent, not zero.

This record describes the stated 2017 U.S. configuration only; it does not represent every trim or model year in the generation.
Manufacturer-published millimeter dimensions are retained. Separately published inches may differ slightly because of rounding. Height is specified for an unladen vehicle.
Propulsion output is the 151 hp (113 kW) traction motor rating. The fuel-cell stack’s separate 153 hp rating is not wheel-driving motor output.
Hydrogen fuel generates electricity on board. MPGe is gasoline-equivalent efficiency, not gasoline MPG; EPA range is on a full hydrogen fill, not a plug-in battery charge.
EPA classifies the transmission as automatic. No physical gear count or CVT mechanism is inferred from its variable-gear-ratio database label.
