How efficient is it?
As an all-electric vehicle, the 2015 BMW i3 BEV is rated in MPGe rather than MPG, and running costs are dominated by electricity rather than fuel. That is about 425% better than the typical Subcompact Cars of its era (24 MPG class average), making it one of the more efficient choices in its class.
Fuel economy and running costs
At about $600 per year in fuel (EPA estimate, 15,000 mi/yr), fuel is a major part of the cost of owning the 2015 BMW i3 BEV. Over five years that is roughly $3,000 at today's prices — before insurance, maintenance, and depreciation.
How to read these numbers
EPA figures come from standardized laboratory test cycles and are the same estimates shown on the vehicle's window sticker. Your real-world mileage depends on driving style, conditions, fuel grade, and maintenance. Use combined MPG and annual fuel cost to compare vehicles fairly.
