City or highway — who is this car for
The BMW 750e gives up 3 mpg the moment you leave the motorway — 26.5 out there against 23.5 in town, a 13% drop worth $185 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 | 23.5 mpg | $1,634 a year if you only drive in town |
| Highway | 26.5 mpg | $1,449 a year if you mostly commute |
| Gap | +3 mpg (13%) | Narrow — equally happy either way |
