The official government MPG figures published in sales brochures can tempt you into buying a particular car, but those results can be 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, we use strictly controlled laboratory conditions, but the tests are based on a real-world route that takes in town, rural and motorway driving.

The results reflect what's achievable if you’re driving gently and sticking to speed limits but aren’t resorting to any unrealistically slow acceleration or special 'hypermiling' techniques.

In this slideshow, we count down the 10 most efficient MPVs and estate cars we've tested so far – plus we reveal the models that used the most fuel.
