City or highway — who is this car for
The Rolls-Royce Phantom gives up 7.1 mpg the moment you leave the motorway — 18.5 out there against 11.4 in town, a 62% drop worth $1,292 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 | 11.4 mpg | $3,368 a year if you only drive in town |
| Highway | 18.5 mpg | $2,076 a year if you mostly commute |
| Gap | +7.1 mpg (62%) | Wide — this car dislikes traffic |
