The Mini Countryman JCW has been spied undergoing testing on the Nürburgring.

Dressed in black and yellow camouflage, the high-performance model features an aggressive front fascia with a honeycomb mesh grille and larger air intakes.  Moving further back, we can see a reduced ride height, sportier side skirts, and five-spoke alloy wheels that are backed up by a beefier braking system with red calipers.   The styling changes are less noticeable out back but the model has a new rear bumper and a sporty dual exhaust system.

The unique styling will continue in the cabin as drivers can expect to find a leather-wrapped sport steering wheel, sports seats, and a JCW shifter.  Other changes will likely include the addition of stainless steel pedals, a revised instrument cluster, and JCW sill plates.

Like the other John Cooper Works models, the Countryman JCW will be powered by a 2.0-liter TwinPower Turbo four-cylinder engine that produces 228 horsepower and 236 pound-feet of torque.  The engine will be connected to either a six-speed manual or an optional six-speed automatic transmission that sends power to an all-wheel drive system. This will likely enable the crossover to accelerate from 0-60 miles per hour in a little over six seconds.
