BMW I3 MPG by Year & Engine (EPA)

EPA fuel-economy ratings for every rated BMW I3 model year from 2014 to 2021 — each engine and transmission with its official city, highway and combined figures. Over these years the I3 has been offered with Electric, 0.6L 2-cyl powertrains; the most efficient version is the 2016 (up to 39 MPG combined). Electric versions are shown in MPGe — a different unit, listed separately from gas MPG. Every rated gas version calls for premium gasoline.
