Revealed first as a thinly-veiled concept this time last year, the new JCW will enter at the top of MINI’s new Cooper line, right above the already impressive Cooper S hatch.
That theme continues into the cabin, with the JCW’s boasting bigger bolsters and a new trim pattern specific to the model.
But, onto more important things: power.
Motivating the new John Cooper Works hatch is BMW’s 170kW/320Nm 2.0 litre turbocharged four-cylinder petrol engine.
Top power is available from 5200rpm, while peak twist comes online at a low 1250rpm - around 400rpm beyond idle.
Among the new engine’s special features is a larger turbo mounted at the exhaust manifold, along with new pistons, camshaft timing, a 10.2:1 compression ratio and a meaner exhaust system.
Kerb weight in the three-door-only (at this stage, at least) Cooper JCW comes in at 1205kg - which, although relatively light, is around 45kg heavier than the Cooper S.
As with the Cooper S, suspension is by MacPherson struts up front and a four-link arrangement at the rear.
There’s also electro-mechanical power steering and electronic differential lock control.
The JCW’s standard 17-inch alloys are wrapped in 205/45 rubber (18-inch can be optioned), sitting in front of Brembo callipers and ventilated performance discs.
This all comes together to make the new JCW the most powerful production model ever to wear a MINI badge, comfortably outdoing the 155kW JCW of the previous Cooper generation - not to mention the extra-special 160kW/240Nm JCW GP that was offered in super limited numbers.
With its six-speed auto shifter, MINI promises a 0-100km/h time of just 6.1 seconds - again bettering its predecessor by more than half a second.
The six-speed manual is nearly as impressive, requiring 6.3 seconds.
Fuel consumption is listed at 6.7 l/100km with the manual, dropping to 5.7 with the automatic shifter. Both figures may require some gingerly driving to be achieved, however.
Watch for the new JCW hot hatch to hit Australia around the middle of next year.
