Best MPG Cars 2017
A key factor when buying a new car in 2017 is to find a model with good fuel economy to minimise running costs. In addition to saving direct fuel costs, cars with high MPgit p also have lower tail-pipe CO2 emissions and hence lower car tax and company car tax.
The list below shows the cars with best fuel economy available to buy new in 2017 across all categories. Electric and plug-in hybrid cars have been excluded from this list as they do not have a directly comparable MPG figure.
Use the search facility below to find best MPG by vehicle class or other criteria. If you wish to conduct a broader search, include electric cars in the results or search used cars go to the main car search page.

What is the source of these MPG figures?
MPG figures on the list of Best MPG Cars above are a combination of Official MPG figures and Real MPG figures estimated by Next Green Car.
The official MPG figures come from the New European Directive Cycle (NEDC). Performed on a rolling road, these official tests are used for emissions certification of light duty vehicles in Europe, and from which fuel economy figures are calculated (rather than measured). The official tests generate the familiar ‘urban’, ‘extra-urban’ and ‘combined’ official figures.
Urban – reflects city driving with lower speeds, frequent breaking, stop-start and higher gears resulting in the lowest MPG figure
Extra-urban – mirrors motorway driving and driving on country routes – higher speeds, infrequent stopping and lower gears. Hence this value is higher than the Urban or Combined
Combined – is an average of the figures from the urban and extra-urban tests weighted to take account of the miles driven in each.
In reality, drivers find it very hard, if not impossible to reach these MPG figures as the NEDC test is conducted in very specific conditions and does not reflect the real-world. Thus it should be seen as a comparative figure, rather than an absolute figure.
To provide a more realistic number, Next Green Car has calculated a Real MPG figure for all 50,000 models in the database. This figure is based on research into actual performance at a model level and involves the use of correction factors based on fuel type and year. See the Real MPG page for more information.
