The official government MPG figures published in sales brochures can tempt you into buying a particular car, but those results are often misleading. So, What Car? has its own  True MPG figures which reveal what fuel economy you can expect in the real world.

To ensure accuracy and repeatability, we use strictly controlled conditions, with the tests simulating a mix of town, rural and motorway driving.

As a result, they 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.

We count down the top 10 the hybrids we've tested that you don't have to plug in, culminating in the new number one.
