Most economical cars
It's slightly cheaper than it once was, but fuel remains one of the biggest costs facing UK motorists. Where your average hatchback might only have managed 35mpg 10 years ago, it's not uncommon to find cars that’ll manage twice that these days.
That's even better news when you consider that there are more fuel-efficient models available than ever before.
When you think of fuel-efficient cars, you might think of electric cars or hybrids – and with very good reason. But continual advances in petrol and diesel engine technology means they’re improving all the time.
You won’t be surprised to see a few hybrids (like the Toyota Prius) on this list, along with plug-in hybrid models, which can be charged from a household socket overnight and driven like an electric car. But when their battery is drained, a conventional engine cuts in to increase the car's range.
Diesel provides the best fuel economy of all conventionally powered cars, even if they are currently under scrutiny due to the emissions they produce. The Peugeot 208 1.6 BlueHDi 75 S&S (Stop & Start) is capable of an incredible 94.2mpg, if you drive carefully.
If you’re looking for a car that produces very low CO2 emissions – to beat the London Congestion Charge or to benefit from free road tax – we’d also suggest reading our guide to the best hybrids. Or check out our guide to the best electric cars for the ultimate in low running costs.
Because it's impossible to compare fuel economy against the cost or usability of an electric car, we’ve excluded them from our list. But you can find out which are the best in our top 10 electric cars feature. And the cars below aren’t in order of possible miles per gallon – they’re all frugal, but are listed in order of our overall preference.
