The mpg figures published in sales brochures can be one of the main reasons for choosing a particular car, but those results are often misleading. Fortunately, What Car?'s True MPG tests reveal what sort of fuel economy you can expect in the real world.

To ensure accuracy and repeatability, our tests are conducted under strictly controlled laboratory conditions but based on a real route that takes in urban, A-road and motorway driving.

In this slideshow we'll look at the most (and least) efficient SUVs we've tested so far.
