Mini Cooper Works versions of the revised BMW Mini Cooper S get a power boost to 211-horsepower, and will sprint to 100kph in 6.5 seconds.
The cars, announced in Europe and on sale there for the northern hemisphere summer, have a larger twin-scroll turbocharger and direct petrol injection with common rail, and the engine has been modified to the same specification as the Mini Challenge race cars.
The Works cars also get re-engineered brakes, suspension and strengthened gears. BMW says the John Cooper Works cars now deliver 132 horsepower per litre. Top speed is around 240kph, and the cars are available in hatchback and Clubman wagon form.
Peak torque is 260Nm, with 280 available for brief periods on overboost. Changes to the 1.6-litre engine include modifications to the air filter, air mass meter, exhaust system and catalyst. Air is fed to the modified turbocharger by a larger air intake pipe, creating a quicker induction phase. It has specially polished pistons and a strengthened cylinder head. The intake valves and valve seat rings have been upgraded. The turbocharger’s maximum boost pressure increases from 0.9 to 1.3 bar, and peak torque arrives at. 1850rpm. Even greater chassis rigidity can be achieved by ordering the John Cooper Works suspension that lowers the entire car by 10mm.
Front brake discs are 425mm, rears are 400mm, and the callipers are uprated and painted red. The brake discs are about 22mm larger than the standard Cooper S’s. Standard gear include a leather sports steering wheel, air-conditioning, interior trim in glossy Piano Black and an Anthracite roof lining. An upgraded sound system is included in the JCW package and has 10 speakers and an eight-channel amplifier. For the first time, the Mini speedo has been increased to 160mph (260kph) on the dial to accommodate the higher maximum speed of the JCW. 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. Works Minis come with exclusive 17-inch light-alloy wheels in JCW Cross-Spoke Challenge design, and are shod with run-flat tyres, and weigh less than 10kg 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.
