The Fiat 500X does 26.8 mpg combined (24.4 city, 31.1 highway), which works out to about $1,433 a year in fuel at $3.20 a gallon and 12,000 miles. Engine choice matters more than you'd think: 1.4L 4-cyl does 28 mpg while 1.3L 4-cyl does 26 — a difference of $106 a year. Against other 4-cyl cars it sits above the average of 25.4 mpg.
Every Fiat 500X engine, compared
Picking the right version of the same car often saves more fuel than picking a different car altogether. Yearly cost assumes 12,000 miles at $3.20 a gallon.
| Engine | Combined | City / Highway | Years | Fuel per year |
|---|---|---|---|---|
| 1.4L 4-cyl | 25 / 33 | 2016–2018 | $1,371 | |
| 1.3L 4-cyl | 24 / 30 | 2019–2023 | $1,477 |
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 | $0.119 |
| Fuel per year | $1,433 |
| Fuel over five years | $7,165 |
| Against other 4-cyl cars | −$79 a year |
| EPA's own estimate | $2,531 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 | 24.4 mpg | $1,574 a year if you only drive in town |
| Highway | 31.1 mpg | $1,235 a year if you mostly commute |
| Gap | +6.7 mpg (27%) | Typical for its type |
How the 500X 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.

| 2023 | 24 / 30 | 1 | $1,477 | |
| 2022 | 24 / 30 | 1 | $1,477 | |

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.
