Packing the most powerful engine ever brought to a series production Mini, it is set to go on sale in the UK on 25 April at a starting price close to the £22,460 of its predecessor.
As tradition dictates, the new John Cooper Works is based around the three-door Cooper S and receives a series of styling upgrades to reflect its enhanced performance potential.
Included is a unique front bumper with enlarged air ducts, revised LED headlights, altered wheel arch cladding, wider sills, a more prominent spoiler atop the rear hatch, a deeper rear bumper and a pair of centrally mounted chromed tail pipes.
Power for the new front-wheel-drive supermini comes from a revised version of the standard Cooper S’s turbocharged 2.0-litre four-cylinder petrol engine – the B48 as it is known internally at Mini's parent company BMW.
It delivers 228bhp between 5200rpm and 6000rpm, along with 236lb ft from just 1250pm through to 4800rpm.
These are a 20bhp and 29lb ft increases on the turbocharged 1.6-litre four-cylinder petrol engine used by the second-generation Cooper S John Cooper Works, and is 39bhp and 25lb ft more than that offered by the milder version of the turbocharged 2.0-litre four-cylinder petrol engine used in the third-generation Cooper S.
