|---|---|---|---|---|
| 3.5L 6-cyl Hybrid | 29 / 28 | 2025–2025 | $1,324 | |
| 2.4L 4-cyl Hybrid | 27 / 28 | 2024–2026 | $1,422 | |
| 2.4L 4-cyl | 21 / 27 | 2024–2026 | $1,670 |
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 | $0.126 |
| Fuel per year | $1,518 |
| Fuel over five years | $7,590 |
| Against other 4-cyl cars | +$6 a year |
| EPA's own estimate | $3,067 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 | 24.3 mpg | $1,580 a year if you only drive in town |
| Highway | 27.5 mpg | $1,396 a year if you mostly commute |
| Gap | +3.2 mpg (13%) | Narrow — equally happy either way |
How the TX 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 |
|---|---|---|---|---|
| 2026 | 24 / 27.5 | 2 | $1,536 | |
| 2025 | 25 / 27.5 | 2 | $1,477 | |
| 2024 | 24 / 27.5 | 2 | $1,536 |

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.
