What it costs to fuel
Across its configurations, the 2018 Clarity costs about $650 to $1,550 a year to fuel at the EPA's 15,000-mile basis, averaging roughly $1,100. Over five years that is about $5,500 in fuel alone before maintenance, insurance and depreciation — which is why the running cost, not just the price, decides what a car really costs.
Relative to an average new vehicle, the most efficient Clarity configuration saves about $8,250 in fuel over five years; less efficient versions spend more.
For context, the average combined economy of midsize cars in this dataset is about 32 MPGe. The Clarity sits roughly 46 MPGe above that mark at its midpoint, making it more efficient than average for its EPA class.
