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 | $0.160 |
| Fuel per year | $1,920 |
| Fuel over five years | $9,600 |
| Against other V6 cars | −$19 a year |
| EPA's own estimate | $3,100 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 | 18.0 mpg | $2,133 a year if you only drive in town |
| Highway | 24.0 mpg | $1,600 a year if you mostly commute |
| Gap | +6 mpg (33%) | Wide — this car dislikes traffic |
How the 9-4x changed over the years
Combined figure by model year. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
| Model year | Combined | City / Highway | Engines offered | Fuel per year |
|---|---|---|---|---|
| 2012 | 18 / 24 | 1 | $1,920 | |
| 2011 | 18 / 24 | 1 | $1,920 |

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.
