The official government MPG figures published in sales brochures can tempt you into buying 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, 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.

10. Audi SQ7

2018 Audi SQ7 Vorsprung review – price, specs and release date

True MPG 30.8mpg

Go for the sporty S version of the Audi Q7 and more than 30mpg is realistic. That's not bad when you consider that it weighs more than two tonnes and can blast from 0-60mph in just 4.6sec.

9. Volvo XC90 D5

New Land Rover Discovery vs Audi Q7 vs Volvo XC90

True MPG 31.9mpg

The latest Volvo XC90 combines a high-quality, spacious and versatile interior with plenty of kit and precise handling. Just bear in mind that you have to put up with a rather firm ride, while its economy is only slightly better than the SQ7's, despite that being a much faster car.

8. Porsche Macan Diesel

New Maserati Levante vs Porsche Macan

True MPG 32.8mpg

Porsche no longer offers this diesel version of the Macan, but if you can find one on the used market, you'll be getting an SUV that combines a 32.8 True MPG figure with handling worthy of a hot hatch.
