The Tesla Model X does 99.3 mpg combined (101.8 city, 96.5 highway), which works out to about $387 a year in fuel at $3.20 a gallon and 12,000 miles. Against other Electric cars it sits below the average of 99.7 mpg.
Every Tesla Model X 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 |
|---|---|---|---|---|
| Electric | 101.8 / 96.5 | 2016–2026 | $387 |
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 | $0.032 |
| Fuel per year | $387 |
| Fuel over five years | $1,935 |
| Against other Electric cars | +$2 a year |
| EPA's own estimate | $755 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 | 101.8 mpg | $377 a year if you only drive in town |
| Highway | 96.5 mpg | $398 a year if you mostly commute |
| Gap | +-5.3 mpg (-5%) | Narrow — equally happy either way |
How the Model X 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.

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.
