What it costs to fuel
Across its configurations, the 2017 3 Series costs about $2,600 to $3,450 a year to fuel at the EPA's 15,000-mile basis, averaging roughly $3,029. Over five years that is about $15,147 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, this 3 Series configuration spends about $1,500 more on fuel over five years.
For context, the average combined economy of compact cars in this dataset is about 29 MPG. The 3 Series sits roughly 1 MPG above that mark at its midpoint, making it more efficient than average for its EPA class.
