City or highway — who is this car for
The Lexus ES gives up 6.3 mpg the moment you leave the motorway — 31.8 out there against 25.5 in town, a 25% drop worth $298 a year. 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 | 25.5 mpg | $1,506 a year if you only drive in town |
| Highway | 31.8 mpg | $1,208 a year if you mostly commute |
| Gap | +6.3 mpg (25%) | Typical for its type |
How the ES changed over the years
The ES peaked in 2026 at 46 mpg (48 city, 44 highway) and was at its thirstiest in 1994 at 18 — 28 mpg apart, or $1,298 a year in fuel between buying one year and the other. The 2026 car does 46. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
