True MPG: The most and least efficient SUVs
What Car?'s True MPG tests show what you can really expect from a car. Here, we reveal the top 10 most and least efficient SUVs we've ever tested...
The official MPG figures published in car sales brochures can tempt you into buying a particular model, but the results are often misleading.
Fortunately, What Car?'s True MPG Calculator can tell you what sort of fuel economy you can actually expect to get in the real world.
The results reflect what's achievable if you drive gently, stick to speed limits, but don't resort to any unrealistically slow acceleration or special 'hypermiling' techniques.
To ensure that our tests are accurate and consistent across all the different cars we run them on, we use strictly controlled conditions. They're based on realistic driving on a real-world route that takes in town, rural and motorway roads.
Here, we count down the 10 most efficient SUVs we've tested – plus we reveal the one that used the most fuel.
