What it costs to fuel
Across its configurations, the 2020 Z4 costs about $2,950 to $3,050 a year to fuel at the EPA's 15,000-mile basis, averaging roughly $3,000. Over five years that is about $15,000 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 Z4 configuration spends about $3,250 more on fuel over five years.
For context, the average combined economy of two seaters in this dataset is about 23 MPG. The Z4 sits roughly 4 MPG above that mark at its midpoint, making it more efficient than average for its EPA class.
