MPG, running costs & CO2 Rating

4.5 out of 5

Ultra-efficient engines, strong used prices and MINI’s good-value 'TLC' pre-paid service pack all mean that MINI five-door running costs should be low, although participants in our Driver Power survey suggest that this isn't always the case.

Making the case for the five-door stronger still is that MINI charges just £600 compared to the three-door for the two extra doors, a price that nets you additional rear-seat space and a bigger boot. The five-door shouldn’t be too expensive to insure, either, since it falls into insurance groups 13 (for the MINI One) to 29 (for the MINI Cooper S Exclusive auto).

MINI 5-door MPG & CO2

The MINI five-door is an economical and efficient car that’s perfect for private as well as business users. The MINI One is claimed to manage between 47.1-48.7mpg (according to stricter WLTP testing) and emits 132-137g/km of CO2, earning it an upper tier BiK rating. Step up to the more powerful Cooper and fuel economy is down to 44.8-47.9mpg and emissions of 133-142g/km. The Cooper S is the fastest MINI with five-doors, making it slightly less efficient with fuel economy of up to 43.5mpg and CO2 emissions of 148-155g/km depending on specification. Automatic MINIs will probably be scarcer than manuals on the secondhand market, so they may just be worth a bit more when the time comes to sell or trade-in.

After the first year, every MINI five-door costs £150 a year to tax.

Insurance group

Depending on the model, the MINI five-door falls into insurance groups 13 to 29. The carmaker sells its own MINI insurance cover, but as always with motor insurance, it’s always worth shopping around to get the best possible deal.


The standard MINI warranty covers the car for unlimited miles up to three years, which is better than those capped at 60,000 miles, but not as generous as Hyundai’s five-year or Kia’s seven-year policies. However, it’s probably sufficient for buyers on a typical three-year finance deal. If you decide to keep your MINI five-door for longer than that, you can buy an extended warranty before the official cover ends.


It’s worthwhile choosing the TLC package, which covers servicing for three years or 36,000 miles for £300 and can be transferred to the car's next owner.
