City or highway — who is this car for
The Nissan NX gives up 10.7 mpg the moment you leave the motorway — 34.7 out there against 24 in town, a 45% drop worth $493 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 | 24 mpg | $1,600 a year if you only drive in town |
| Highway | 34.7 mpg | $1,107 a year if you mostly commute |
| Gap | +10.7 mpg (45%) | Wide — this car dislikes traffic |
