True MPG: most efficient SUVs

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 SUVs we've tested – plus we reveal the one that used the most fuel.


The 10 most fuel efficient SUVs

10. Suzuki Vitara 1.6

Mazda CX-3 vs Skoda Yeti vs Suzuki Vitara

True MPG 47.7mpg

While the original Suzuki Vitara was a tiny, rugged 4x4, the latest version is more of a rival to city-friendly models, such as the Nissan Juke and Seat Arona. Unfortunately, this 1.6-litre petrol version has now been discontinued.

Used Mazda CX-5 17-present

True MPG 48.3mpg

The CX-5 is a five-seat large SUV with a spacious and comfortable interior, and this diesel version is both refined and economical. Most of the CX-5's rivals offer the option of seven seats, but if you don't need them then it should definitely be on your shortlist.

8. Kia Niro Hybrid

Used Kia Niro (16-present)

True MPG 50.1mpg

It doesn't make as much sense as the fully electric e-Niro, but this hybrid model still topped 50mpg in our test, while its practical interior and seven-year warranty are further plus points.
