Just like the hatchback version, the JCW Convertible is available with a six-speed automatic or a six-speed manual gearbox, the latter as fitted in our test car. The manual is likely to be the best seller, even though it has a long throw and can feel a bit notchy when shifting.
Having said that, if you select Sport mode, which is the most aggressive of the three driving modes, the JCW encourages you to hold onto a gear longer before changing up, allowing you longer to enjoy its glorious overrun crackle.
In Sport mode, as you would expect, the JCW’s throttle response is at its sharpest. Select Normal mode and the throttle feels fairly responsive, but also softer and probably more ideal for everyday use. The steering feels weighty, with the convertible’s tidy body control helping to maintain the Mini’s direct, highly strung handling.
Our JCW Convertible test car came fitted with 18in John Cooper Works Cup alloys as part of the £2400 Chili pack, trimmed with run flat tyres. Those wheels, combined with the firm suspension setup, means the Mini never really feels settled on any asphalt bar the very smoothest. The vibrations pass through the cabin but at no point does it spoil the comfort of the occupants. Over the larger protrusions and potholes, the JCW crashes from one to another, causing a sizeable thud in the cabin, with the biggest ones really catching the hot Mini out.
Up front the Mini’s JCW’s sports seats are comfy and supportive and provide enough adjustment to get settled, while the dashboard is solidly built and accented with gloss and chrome trim to help enhance the interior. Our test car came fitted with BMW’s iDrive-based Media XL infotainment system with an 8.8in screen and Harman Kardon audio that, although costing an extra £1990 altogether, are very decent companions to have.
The rear seats remain best-suited for youngsters, while the boot will offer 215 litres of space with the roof and divider up. Opt for the al fresco experience and the boot space will shrink to 160 litres, which should still be enough room to fit a couple of soft holdalls in the boot.
Should I buy one?
The Mini John Cooper Works Convertible is a very likeable car and provides a more affecting roof-down character than the hatch. However, the JCW hatchback's superior handling dynamism should still draw those most interested in buying a pure driving machine.
Compared to its nearest rivals, the Abarth 595C and the DS 3 Performance Cabriolet, the JCW may be far more expensive but remains a better car to drive and is a proper convertible.
The biggest conundrum for this JCW Convertible is that the Mini Cooper S Convertible ticks many of the required boxes without such a hefty price tag, or sounding quite as purposeful at full chat. However, it accelerates, stops, turns and goes about its business as a convertible in a similar manner, and while the JCW badge will attract numerous buyers, those with one eye on their budget will probably find the Cooper S an equally compelling buy.
