4 Series MPG Questions
Which 4 Series year gets the best gas mileage?

Does all-wheel drive hurt 4 Series fuel economy?
A little. On the 2027 4 Series, the best rear-wheel drive version is rated at 31 MPG combined and the best all-wheel drive version at 30 MPG.
Why doesn't my 4 Series match the EPA numbers?
EPA ratings come from standardized lab tests so every car is measured the same way. Your results depend on speed, climate, idling, cargo, tire pressure and upkeep. The ratings are best for comparing one car against another. To track your own numbers, try the MPG calculator.

Where These Numbers Come From
This page was built by Cedrick Reese from the U.S. EPA fuel economy dataset on fueleconomy.gov, which holds 175 ratings for the BMW 4 Series from 2014 to 2027. Each row in the table links to the matching EPA vehicle record, so you can check any figure against the source. When the EPA posts an updated file with new model years or corrected ratings, this page is rebuilt from it. The cost calculator uses the gas price you enter rather than a national average, so the result fits where you live.
Ratings on this page come from the EPA file downloaded on October 1, 2026.
