The Rolls-Royce Cullinan gives up 7.4 mpg the moment you leave the motorway — 19.3 out there against 11.9 in town, a 62% drop worth $1,237 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 | 11.9 mpg | $3,227 a year if you only drive in town |
| Highway | 19.3 mpg | $1,990 a year if you mostly commute |
