MPG and running costs
BMW quotes an WLTP figure of 32.8-33.6mpg for the xDrive30d, and that tallies with the real-world experience during our test. Urban running doesn’t allow the X7 to really get into its stride and make the most of the tall eighth ratio, even though there is generous torque, but a steady cruise gives more opportunity to eke out the miles.
The optional Active Cruise Control has more finesse than some systems and will avoid heavy braking and acceleration unless absolutely necessary, helping to boost the range of approximately 480 miles on a long motorway journey.
