The official government MPG figures published in sales brochures can tempt you into buying a particular car, but those results can be 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, our tests are conducted under strictly controlled laboratory conditions but based on a real route that takes in urban, A-road and motorway driving.
Best real MPG MPVs and estates
10. Volvo V90 D4
Official fuel economy: 62.8mpg True MPG: 40.2mpg Shortfall: 35.9%
Volvo's luxurious V90 estate is priced against premium rivals including the Audi A6 Avant and BMW 5 Series Touring – both of which also appear on this list. The V90 might not be as economical as those, but it's still comfortable and spacious and has a quality interior.
Official fuel economy: 62.8mpg True MPG: 40.7mpg Shortfall: 35.2%
It may not have the biggest boot here – that accolade goes to the Mercedes-Benz E-Class – but the A6 Avant has the quietest and classiest interior. If you choose the frugal 2.0 Ultra diesel engine, it’ll also be pretty painless on your wallet, with real-world fuel economy of 40.7mpg.
Official fuel economy: 67.3mpg True MPG: 41.2mpg Shortfall: 38.9%
The E-Class Estate is pricier than rivals such as the BMW 5 Series Touring and Audi A6 Avant, but if you're planning on loading it full of people and luggage, then you'll be pleased to note it's got the biggest boot of the three. It’s not the most driver-focused car, but it probably is the most comfortable long-distance family cruiser.
