Best Highway MPG Vehicles
The 2025 Lucid Air leads at 142 mpg, followed by the Tesla Model 3 at 133 mpg.
Highway economy rewards aerodynamics and tall gearing rather than hybrid assistance. If your driving is mostly steady-speed, this list predicts your real fuel bill better than the combined rating does.

How the highway mpg figures compare
Across the 25 vehicles ranked here, highway mpg runs from 106 mpg for the 2027 Chevrolet BOLT up to 142 mpg for the 2025 Lucid Air — a spread of 36 mpg, or about 34% between the bottom and top of the list. The midpoint sits at 115 mpg, 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 BMW with 3. In total 12 manufacturers are represented, which is a useful read on how widely this level of highway mpg is available rather than being confined to a single badge.
Estimated annual fuel cost across these entries ranges from $500 to $700 on the EPA's standard 15,000-mile driving assumption — a difference of $200 a year, or roughly $1,000 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
The EPA highway cycle averages about 48 mph with gentle acceleration. Sustained speeds above 70 mph, roof racks, and headwinds all cut meaningfully into these figures.
