The new Sports exhaust system is instantly recognisable through the large polished stainless steel twin tailpipes. Modification of the exhaust system has also helped to reduce counter-pressure at the point of exhaust gas recirculation. Ducts in the exhaust manifold and turbocharger are split between two cylinders each. Congestion is therefore minimised when air is inducted to the turbocharger and "turbo lag" is virtually eliminated.
The John Cooper Works MINIs are the first models in the range to fulfil all the requirements of the European EU5 emission standards that come into force in 2009.
The material used in machining the turbine has been upgraded specifically for the Works engine, with maximum charge pressure increased from 0.9 to 1.3 bar, in order to maintain the highest possible temperature for a longer period in the combustion chambers. This lengthening of the combustion process helps to achieve the higher torque curve of the Works car at 260Nm at just 1,850rpm. The Overboost function briefly extends this further to 280Nm. This suits the character of a John Cooper Works car perfectly as Overboost is experienced exclusively through increased torque, not on engine output.
Safety and Driving Dynamics
DTC allows controlled slip on the drive wheels. For example, on a slippery surface, the driver can pick up speed in a controlled manner with the front wheels spinning slightly. When reaching the upper limit, DSC will intervene as usual. But the driver can deactivate the DSC/DTC systems if he wishes by the touch of a button.
In the DSC-off mode, the standard Electronic Differential Lock can be activated and controls cornering at higher speeds. If one wheel loses grip, drive is transferred to the wheel with better grip promoting the car's traction and pulling force.
Chassis
The Sports Suspension has been specifically tuned for the Works models. However, even greater chassis rigidity can be achieved by ordering through dealerships the John Cooper Works suspension that lowers the entire car by 10mm.
Extra-large disc brakes adorned with uprated red callipers are fitted to Works cars. In addition, inner-vented discs are positioned behind the front wheels. The front discs are 17" in diameter while the rear set measure 16". The brake discs are approximately 22mm larger than on the standard Cooper S.
Interior
The options included as standard on the John Cooper Works include a leather sports steering wheel, air-conditioning, interior trim in glossy Piano Black and an Anthracite roof lining.
The six-speed manual gearbox has been strengthened to handle the powerful new engine.
The standard Sports button, located in front of the gear stick, activates a bespoke engine control map which produces even more dynamic performance and sharper steering response.
Exterior
The Works MINIs come with exclusive 17" light-alloy wheels in JCW Cross-Spoke CHALLENGE design, shod with Run-flat tyres, and weigh less than 10 kilos each.
The Works models can be identified by the newly-designed John Cooper Works logo on the boot and grille and wheels, as well as on the door trim.
