City or highway — who is this car for
The Genesis G70 gives up 8.4 mpg the moment you leave the motorway — 27.9 out there against 19.5 in town, a 43% drop worth $593 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 | 19.5 mpg | $1,969 a year if you only drive in town |
| Highway | 27.9 mpg | $1,376 a year if you mostly commute |
| Gap | +8.4 mpg (43%) | Wide — this car dislikes traffic |
How the G70 changed over the years

Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
