Mini has revealed its new Clubman All4 five weeks before the model debuts at the New York motor show.
The Clubman All4 is the all-wheel-drive variant of the current Clubman. It uses Mini’s latest driveline to enable both two- and four-wheel-drive as well as torque vectoring.
The use of a hang-on clutch in the system enables the All4 to decouple the rear and operate in front-wheel-drive under normal circumstances, helping to save fuel and reduce torque losses by up to 30%. However, when the system detects slip, it can engage the variable clutch and immediately direct torque rearwards via a two-part prop-shaft.
The whole system works with the car’s driving dynamics system, which can independently brake or send torque to each wheel for full torque vectoring. It can improve agility by doing things like braking the car’s inside wheels and sending torque to the outside wheels during hard cornering, helping to tighten the car’s line.
There are also obvious benefits to traction in low-grip scenarios, such as snow and ice.
Engine and transmission
Just two engines from the Mini line-up are available at launch. The first is the turbocharged 2.0-litre four-cylinder petrol engine from the Cooper S, which produces 189bhp at 5000rpm and 206lb ft of torque at 1250rpm (this grows to 221lb ft during short stints of overboost).
Mated to the standard six-speed manual gearbox, the Cooper S Clubman All4 can sprint from 0-62mph in a claimed 7.0sec, and will keep on accelerating on until 140mph. This is two-tenths quicker and 2mph slower than the two-wheel-drive alternative.
