City or highway — who is this car for
The gap between city and highway figures tells you whom the car suits. A wide gap punishes stop-and-start traffic; a narrow one means the car doesn't care where you drive it.
| Measure | Value | Reading |
|---|---|---|
| City | 15.0 mpg | $2,560 a year if you only drive in town |
| Highway | 21.3 mpg | $1,803 a year if you mostly commute |
| Gap | +6.3 mpg (42%) | Wide — this car dislikes traffic |

How we count
Fuel-economy figures come from EPA fueleconomy.gov — the same laboratory numbers printed on the window sticker. We don't adjust them; real-world consumption depends on how and where you drive.
What we add is money. Yearly cost assumes 12,000 miles at $3.20 a gallon — change either and the ranking stays, only the size of the bill moves. Cost per mile is the same figure divided out, useful when comparing a commute against a weekend car.
