Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 20 - 38 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

The X6 is a big, heavy car with powerful turbo-charged engines so running costs aren’t going to be cheap. BMW X6 running costs won't be helped by high premiums. Insurance is between groups 18 and 20, road tax and fuel costs are high and BMW servicing and parts aren't cheap. On the plus side BMW does offer a servicing deal called Service Inclusive which, for one up-front payment, covers new owners for five years or 60,000 miles of maintenance.

Usefully this can be transferred onto subsequent owners.

This is not a car that will please the environmental lobby, but BMW has applied its useful Efficient Dynamics technology such as brake energy regeneration to reduce the X6’s environmental impact. BMW X6 emissions are high though. The two diesel versions emit less than 225g/km of CO2 so aren’t hit with the highest car tax charge and can both average 34mpg.

BMW X6 reliability should not be a concern. The German car maker enjoys a good reputation for reliability so there is little reason to think the X6 will be anything but. It is fitted with a lot of technology but most of it is well proven in other cars in the range.
