Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 32 - 40 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Residuals will be so good that you’ll be able to buy one, run it for a year then sell it for the price you paid for it. A maintenance package covers all servicing for five years. Fuel is good and insurance isn’t bad either.

Convertible scores reasonably on the eco front. With an average of 191 g/km CO2 across the line-up, its emissions are fairly standard for a super mini convertible. It’s worth noting that the line-up does not feature any diesel models, which typically produce less carbon dioxide than petrol engines with similar power outputs. The range is not particularly economical, averaging 35 mpg.

This is essentially a BMW and it benefits from solid German engineering. Early MINI suffered plenty of recalls but all were sorted under warranty. All early problems have now been ironed out, which the convertible benefits from. Run-flat tyres are a useful option.
