KEY POINTS:
The John Cooper Works range of high-performance Minis will be complete next month when the carmaker unveils the JCW convertible at the Geneva motor show.
Despite losing its roof, the drop-top Mini is as potent as the other JCW models, the two-door hatchback and Clubman carry-all.
The new Mini uses the same mechanical package, a twin-turbocharged 1.6-litre engine producing 155kW and a maximum of 280Nm of torque and driving the front wheels via a six-speed manual gearbox.
Performance is down slightly on the hatchback, mostly because of the extra weight used in strengthening the soft-top's chassis.
JCW says the convertible sprints from zero to 100km/h in 6.9 seconds and on to a top speed of 236km/h. A sport button in front of the gear stick activates a bespoke engine map, which improves steering and throttle response instantly.
To help get the power down, an Electronic Differential Lock Control is fitted. It works in a similar way to Alfa Romeo's Q2 system, by braking the spinning inside wheel to maximise traction out of corners.
Standard kit is much improved over the Cooper S and includes a unique Alcantara steering wheel, figure-hugging sports seats and a glossy piano black interior finish.
Outside, there's exclusive 17-inch cross-spoke wheels, a subtle bodykit and JCW badging on the boot, grille, brakes and door sills.
