What it costs to fuel

Across its configurations, the 2017 3 costs about $2,050 to $2,300 a year to fuel at the EPA's 15,000-mile basis, averaging roughly $2,145. Over five years that is about $10,725 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 3 configuration saves about $1,250 in fuel over five years; less efficient versions spend more.

For context, the average combined economy of compact cars in this dataset is about 29 MPG. The 3 sits roughly 1 MPG above that mark at its midpoint, making it more efficient than average for its EPA class.
