The list below shows the Top 10 best MPG city car models currently available to buy as new in the UK. Finding a city car model with high fuel economy and low emissions can have a significant impact on both fuel bills and other running costs.
Electric cars and plug-in hybrids are excluded from this list of city car models with high MPG as they do not have a directly comparable MPG figure. Select another vehicle class or other criteria to see more high fuel economy cars or use the main car search to find used cars or filter by more criteria.
The official MPG figures for all vehicles, including city car models are derived from the NEDC test. There are two parts to the test: an 'urban' cycle designed to reflect driving in a city environment with many stops and starts and an 'extra-urban' cycle designed to mirror more steady state motorway and country routes. The 'combined' figure, which is the most often quoted figure is an average of 'urban' and 'extra-urban' weighted by the distances covered in each test.
Often drivers find that it is difficult to achieve the official MPG figures, and it is well understood that these rates should be used as a comparison rather than a target to achieve. Next Green Car has estimated a 'Real MPG' figure which reflects real-world conditions more closely. See the real MPG page for more info.
Different city car models can have dramatically different fuel economy, so before purchase it is essential to research into each model carefully to ensure a good fuel economy, with the resultant reduced fuel bills and car tax. High MPG is directly linked to lower tail-pipe CO2 so a city car vehicle with good MPG will also emit a lower level of CO2 emissions into the environment.
