What that actually costs
Miles per gallon is an abstraction; the fuel bill is not. Here it is in money, at 12,000 miles a year and $3.20 a gallon.
| Measure | Value |
|---|---|
| Cost per mile | $0.102 |
| Fuel per year | $1,227 |
| Fuel over five years | $6,135 |
| Against other 4-cyl cars | −$285 a year |
| EPA's own estimate | $2,017 a year |
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 | 30.1 mpg | $1,276 a year if you only drive in town |
| Highway | 33.9 mpg | $1,133 a year if you mostly commute |
| Gap | +3.8 mpg (13%) | Narrow — equally happy either way |

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.
