As with its fixed-roof sibling, buyers get to choose between a standard six-speed manual and optional eight-speed automatic gearbox. They are also supported by a raft of electronic driving aids, including dynamic stability control, dynamic traction control and an electronic differential lock.
Mini claims its new top-of-the-line convertible accelerates from 0-62mph in 6.6sec in six-speed manual guise, making it 0.3sec faster than old John Cooper Works Convertible and 0.2sec faster than the Cooper S Convertible.
With the optional eight-speed automatic, the new Mini model is 0.1sec faster, bettering its predecessor’s 0-62mph time by a creditable 0.6sec and the existing Cooper S convertible by the same amount, at 6.5sec.
Top speed, meanwhile, is 150mph in manual guise and 149mph for the automatic.
As well as boasting improved performance credentials, the new John Cooper Works Convertible also provides better fuel economy; the manual returns a claimed combined cycle figure of 43.5mpg, making it 2.0mpg more economical than the old model, while the automatic betters its direct predecessor by 9.2mpg at 47.9mpg.
Mini’s latest performance model rides on standard 17in wheels shod with 205/45 profile tyres, although 18in rims are available as an option. Along with specific suspension tuning, the new car also receives a Brembo brake system.
As tradition dictates, the John Cooper Works Convertible receives a series of exterior styling upgrades to visually differentiate it from less powerful versions.
Included is a uniquely styled front bumper with enlarged air ducts, a red coloured grille embellishment, revised LED headlights, altered wheel arch cladding, red brake calipers, wider sills, a deeper rear bumper and a pair of centrally mounted chromed tail pipes.
Inside, the new John Cooper Works Convertible sports model-specific sill decoration, more supportive front seats with integrated headrests, a three-spoke multi-function steering wheel, a new gear lever, stainless steel pedals and revised instrument graphics.
Among a long list of options available for the new car is the so-called Mini Yours soft top featuring a woven Union Jack motif, as seen on the early example pictured.
The next model in the John Cooper Works family will be the John Cooper Works Clubman.
