BMW X3 fuel economy

The 'Official MPG' figures for the BMW X3 are derived from the NEDC test. There are two parts to the test: an 'urban' cycle designed to reflect driving in a city environment with many stops and starts and an 'extra-urban' cycle designed to mirror more steady state motorway and country routes. The 'combined' figure, which is the most often quoted, is an average of 'urban' and 'extra-urban' weighted by the distances covered in each test.

Often drivers find that it is difficult to achieve the official MPG figures, and it is well understood that these rates should be used as a comparison rather than a target to achieve. Next Green Car has estimated a 'Real MPG' figure for the BMW X3, which reflects real-world conditions more closely. See the real MPG page for more info.

Even within a model range like the BMW X3, it is worth considering which model to select carefully as the MPG for different models can vary substantially. Fuel economy is directly linked to the tail-pipe CO2 emissions of a vehicle, thus a higher MPG BMW X3 model, will not only result in lower fuel costs but potentially a lower tax rate and less impact on the environment.
