Fuel economy

Petrol engines 37.2 - 45.6 mpg
  • Convertible range is an all-petrol line-up
  • Cooper is the cheapest to run of the lot
  • Performance models aren’t too costly, though

The MINI Convertible is pricier than its DS 3 Cabrio and Fiat 500C rivals (and on a par with high-spec Mazda MX-5s) but continues to define the segment with its blend of agile handling, good performance and fuel efficiency, premium quality and personalisation options.

Most customers will like to keep it simple and opt for the TLC servicing pack. This covers the MINI’s service requirements for the first three years or 36,000 miles, and will transfer to the next owner if you get rid of the car before the end of the three years.

In terms of fuel economy, it’s the Cooper that’s the most fuel-efficient. MINI claims it’ll return up to 54.3mpg (53.3mpg if fitted with larger alloy wheels).

The Cooper S comes next, returning a claimed 44.8mpg, while the fastest JCW comes in slightly lower than this, with official claims of 42.2mpg. Of course, take advantage of the eager engine and fun drive and you won’t see these figures. You’ll more likely see something in the 30s. 

The 1.5-litre engine in the Cooper emits a relatively low CO2 figure of 119g/km.

The 2.0-litre Cooper S – unsurprisingly – is quite a bit higher at 145g/km, while the JCW produces 152g/km of CO2.

All of the Convertible models emit more CO2 than the three- and five-door counterparts.

  • A couple of recalls for the MINI Convertible
  • Feels a solid and well-built small car
  • Should be very few concerns

All of the MINI Convertible’s mechanical and electrical components are shared with various models in the BMW Group, and overall the car feels very solid and well built, especially the premium interior.

There have been a couple of official recalls for the car, though. One regards the spare wheel, another the front seat backrest on early-build cars, and another to do with the airbag.

These issues will have all been sorted out as part of the recall, and there haven’t been any others crop up since, so most issues should be ironed out by now.
