What it costs to fuel
Across its configurations, the 2018 Fiesta costs about $2,100 to $2,250 a year to fuel at the EPA's 15,000-mile basis, averaging roughly $2,167. Over five years that is about $10,833 in fuel alone before maintenance, insurance and depreciation — which is why the running cost, not just the price, decides what a car really costs.

For context, the average combined economy of subcompact cars in this dataset is about 27 MPG. The Fiesta sits roughly 3 MPG above that mark at its midpoint, making it more efficient than average for its EPA class.
