What it costs to fuel
Across its configurations, the 2017 A3 costs about $2,250 to $2,600 a year to fuel at the EPA's 15,000-mile basis, averaging roughly $2,380. Over five years that is about $11,900 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 A3 sits roughly 2 MPG above that mark at its midpoint, making it more efficient than average for its EPA class.
