Two model grades will be offered, starting with the Cooper and topping out with the more sporting $44,100 Cooper S variant.
Those figures represent a circa $2000 premium over the equivalent five-door Countryman models, the Cooper priced at $33,700 and the S at $42,300.
The engines available to Australian buyers will be familiar to fans, the Cooper powered by a 90kW/160Nm 1.6 litre mill, and the Cooper S getting a more powerful 135kW heart.
MINI promises a 10.4 second sprint to 100km/h in the Cooper, while the S model lists a 0-100km/h time of 7.5 seconds.
Six-speed manual and automatic transmissions will be available, and the Cooper S will get MINI's ALL4 all-wheel-drive system.
In Cooper form, the Paceman will offer combined fuel consumption figures of 6.5 l/100km, while the Cooper S lists a very close 6.6 l/100km.
The new John Cooper Works version is also expected down the line, driven by the same 160kW/280Nm engine that drives the JCW-enhanced Countryman.
Features And Dimensions
On the design front, the Paceman carries much of the Countryman's style, while showing off a chopped and tapered roofline and an all-new rear-end design.
Although it has two fewer doors, the Paceman is no smaller than its Countryman donor car, measuring the same 4110mm in length and 1789mm width.
The cabin of the Paceman offers seating for four, and rear storage capacity is listed at 1080 litres with the back seats down, and 330 litres when upright.
By comparison, the Countryman's squarer roofline and taller glasshouse ensures a more capacious rear area, listed at 1170 and 350 litres.
Keeping the Paceman in-line with its sporting looks, MINI has gifted the three-door with a 10mm lower ride height and a re-tuned chassis for improved handling.
The Paceman's feature set largely mirrors the Countryman, while adding a couple of extra tricks.
The Cooper Paceman features Dynamic Stability Control, 16-inch alloy wheels, front and rear fog lights, auto headlights and wipers, Sports leather multi-function steering wheel, Chrome Line interior, and Bluetooth/USB connectivity.
The Cooper S adds Dynamic Traction Control, Sport nutton, 17-inch alloys, clear indicator lenses and stainless steel trim for the pedals and footrest.
Standard kit for both models includes Sports seats and Sports suspension.
