The Mazda Navajo gives up 5.2 mpg the moment you leave the motorway — 20.5 out there against 15.3 in town, a 34% drop worth $637 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 |

| Highway | 20.5 mpg | $1,873 a year if you mostly commute |
