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.

Below, we count down the 10 most efficient prestige SUVs we've tested to date. After all, while you're unlikely to be considering one of these cars if you're on a tight budget, that doesn't mean you want to throw money away unnecessarily.
