City or highway — who is this car for
The BMW 750Li gives up 7.7 mpg the moment you leave the motorway — 22.6 out there against 14.9 in town, a 52% drop worth $878 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 | 14.9 mpg | $2,577 a year if you only drive in town |
| Highway | 22.6 mpg | $1,699 a year if you mostly commute |
| Gap | +7.7 mpg (52%) | Wide — this car dislikes traffic |
How the 750Li changed over the years
