Most Efficient Electric Cars
The 2025 Lucid Air leads at 146 MPGe, followed by the Tesla Model 3 at 142 MPGe.
MPGe converts electricity use into a gasoline-equivalent figure, so a higher number means less energy consumed per mile. It measures efficiency, not range — a large, efficient EV can travel farther than a small one with a better MPGe rating.

How the combined mpge figures compare
Across the 25 vehicles ranked here, combined mpge runs from 116 MPGe for the 2027 BMW i5 up to 146 MPGe for the 2025 Lucid Air — a spread of 30 MPGe, or about 26% between the bottom and top of the list. The midpoint sits at 121 MPGe, so anything above that figure is in the upper half of what this dataset covers.
Tesla places 3 models on the list, the most of any brand, ahead of Hyundai with 3 and Toyota with 3. In total 12 manufacturers are represented, which is a useful read on how widely this level of combined mpge is available rather than being confined to a single badge.
Estimated annual fuel cost across these entries ranges from $500 to $650 on the EPA's standard 15,000-mile driving assumption — a difference of $150 a year, or roughly $750 over a typical five-year ownership period. Read the ranking column alongside that figure: the highest-rated vehicle is not automatically the cheapest to run once fuel type and tank size differ.
What this list doesn't tell you
Efficiency falls in cold weather and at sustained highway speed. Real-world consumption also depends on charging losses, which the EPA figure already accounts for at the wall.
