Mini John Cooper Works review - quick and engaging but suffering from middle-aged spread - MPG and running costs

The JCW is certainly fast and relatively sophisticated for a hot hatch but it’s doesn’t quite have the fun factor of its chief rival

  • Performance, grip, refinement
  • Price, not as involving to drive as the Ford Fiesta ST

MPG and running csts

Despite offering 39bhp and 29lb ft more than the Cooper S, the JCW’s fuel economy isn’t significantly affected and under the WLTP guidelines its combined economy figures range from 38.7 to 40.4mpg, just two or three miles-per-gallon less than the S. Those figures are for the manual, with the automatic version posting nigh on identical results. These should be achievable under gentle driving, but if you use all the performance you’ll see economy down in the 20s.

The extra weight of the convertible makes it slightly less economical, with official combined economy figures of 37.2 to 39.2mpg. Again, figures for the auto are virtually identical.

Revisions made to the JCW in early 2019 included the addition of a particulate filter integrated into the standard sports exhaust system, ensuring it meets the strict Euro 6d-TEMP emission standard. While Mini says it doesn’t affect economy or emissions, there don’t seem to be quite so many pops and bangs from the exhaust as a result. 

Insurance groups are 29 for the hatch and 33 for the convertible which makes it broadly similar to its rivals – a Polo GTI for example is in group 26 or 28. 

Mini JCW servicing costs can be taken care of with a pay monthly deal at £17.99 a month for three years. It only covers two services, so depending on your annual mileage it may or may not be worth considering.
