Most economical cars
The rising cost of fuel means that car manufacturers face a constant battle to make their models cheaper to run. In a way, though, that's a good thing, because today's new car buyers now have even more fuel-efficient cars than ever to choose from, with the most notable offerings surfacing in only the last few years.
Monthly UK car sales results from the Society of Motoring Manufacturers and Traders shows that the number of alternatively fuelled vehicles has grown hugely in the past year or so. That will be largely due to more and more car buyers trying to save money on their fuel bills.
When people think of economical cars, their thoughts automatically turn to hybrids or electric cars, but now even conventional combustion-engined cars (whether they run on petrol or diesel) can be just as economical on fuel.
Unsurprisingly, a fair few cars on this list are either hybrids or run on electric power to some degree. The impressive BMW i3 comes very high on our list, as it is capable of an incredible 470mpg, but cars like the Mitsubishi Outlander PHEV and Toyota Prius are also capable of high fuel economy figures. There's even a Porsche on this list.
The best mpg figures from conventional diesel cars – such as the Peugeot 308 BlueHDi – now far outpace those of petrol ones, while the number of hybrids on sale (which can perform even better in terms of outright fuel economy) has never been bigger. The result is that no car here delivers less than 85mpg.
If you are looking for a car that produces low CO2 emissions – to beat London's congestion charge and get cheap road tax – we would 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.
