MINI hatchback review - MPG, CO2 and running costs

The MINI offers strong economy and, if chosen wisely, a very sound buy that will hold its value well

The MINI has always been quite fuel efficient, but this generation’s range of engines improves things considerably. MINI claims the entry-level 1.5-litre petrol returns a maximum 52.3mpg, with CO2 emissions from 122g/km.

However, given the extra performance on offer it’s remarkable that the more powerful 1.5-litre engine in the Cooper is only marginally worse – 51.4mpg and 124g/km of CO2.

With its extra performance, the Cooper S naturally isn't as economical as the Cooper – 45.6mpg and CO2 of 140g/km – and even more so with the John Cooper Works model which returns 41.5mpg and emits 155g/km.

Specify any MINI with the optional MINI Driving Modes and you’ll be able to choose between Sport, Mid and Green settings. The system alters the parameters of the throttle, steering and air conditioning according to the mode selected. In Green mode it desensitises the accelerator pedal, makes the steering lighter and displays the most economical time to change gears, which can help to save fuel.

If you really want to save on fuel costs there's the MINI Electric which is able to cover around 140 miles on a single charge.

Insurance groups

The MINI’s desirability and BMW servicing costs mean it sits in higher insurance groupings than less ‘premium’ superminis like the Ford Fiesta. Starting in group 13 for a three-door One Classic, the range reaches into group 29 for the JCW model and group 37 for the JCW GP model. The MINI Electric occupies the middle ground in groups 22 to 23.


One benefit of the MINI’s carefully cultivated premium image is that desirability remains very high relative to its ubiquity on UK roads. Our experts predict that three-door models will retain an average of 48% of their value come trade-in time after three years and 36,000 miles, with five-door models performing likewise.

It's worth bearing in mind that decisions on colour and trim can affect MINI values, so choose wisely when you come to buy. Be wary of brighter colours and of loading your car with additional kit and accessories, some of which will add no value. Climate control, satellite navigation and fancier wheels are all options that add to a MINI’s appeal and value on the used market.
