The BMW X6 offers surprising economy but overall running costs will still be high

MPG, running costs & CO2 Rating

2.5 out of 5

Running a BMW X6 isn't a decision to be taken lightly – its running costs are fairly high across the board. The xDrive30d and xDrive40d are the most economical, returning up to 33mpg, but that's not exactly a figure to celebrate. CO2 emissions of 183g/km mean a 37% Benefit-in-Kind (BiK) company car tax bracket – the highest and most expensive there is.

The M50d offers more performance but fuel economy drops still further to 30.1mpg with CO2 climbing to 205g/km.

Every X6 costs well over the £40,000 cut-off above which road tax costs £465 a year, but a lower £145 annual fee is charged after the car's sixth birthday.

Insurance group

Insurance groups for the BMW X6 run from group 42 for the entry-level xDrive30d and rise to group 45 for the xDrive40d and group 48 for the range-topping M50d. Whichever model you choose, expect high premiums.

Warranty

BMW's warranty covers the X6 for unlimited miles for the first three years of ownership. Extended coverage can be purchased once the initial manufacturer cover runs out.

Servicing

To make it easier to manage the cost of X6 maintenance, BMW offers a £30 per month payment plan that covers the car's services for three years and also includes fluid top ups, an MoT, car washes at each visit and free sat nav updates.
