MINI power made in UK.
MINI Cooper S models now also available with the John Cooper Works tuning kit readily fitted at the Oxford plant.
Munich. The John Cooper Works tuning kit, which transforms the MINI Cooper S into an absolute driving machine, can now be ordered as optional equipment readily fitted at the factory. In addition to a power boost to 154 kW/210 bhp and an increase in torque to 245 Nm at 4,500 rpm, the package includes high-performance brakes, great acoustics, a limited slip differential for even better traction, stylish wheels and endless driving fun.
Committed to tradition: MINI and John Cooper Works.
For more than four decades now the name John Cooper has been synonymous with the sporting character of MINI automobiles. As a MINI associate of many years’ standing, John Cooper Works has designed a tuning kit for the top-of-the-range models MINI Cooper S and MINI Cooper S Convertible, with which the nimble four-seater car achieves remarkable performance.
Mike Cooper, son of motor racing legend John Cooper and owner of John Cooper Works based in Sussex in the South of England, is thrilled that his tuning kits are now being installed before the cars leave the factory. “This is proof to all concerned of just how close and successful our collaboration with MINI is. I therefore believe that we will be able to continue in future to provide our customers with many attractive and high performance products”.
Mike Cooper has been heavily involved in the introduction of these exciting new cars at Oxford. Accompanied by Dr. Heiss, head of the Oxford plant, and having personally overseen the installation of the first tuning kits at the assembly line, Cooper commented: “I was most delighted with the Oxford team. The calm and professional way the employees went about their work and the standard of competence are truly impressive. I am now convinced that my tuning kits are in good hands at Oxford”.
Until now, the tuning kit was only available as a retrofitted accessory. However, with immediate effect, the particularly sports-minded customer can order a MINI Cooper S model featuring a manual gearbox with the John Cooper Works tuning kit readily fitted at an additional cost of 4,680 Euros. Delivery of the first cars featuring this optional high-performance equipment will commence in October 2005.
Thoroughbred sports car with compact dimensions.
Thanks to selected “ingredients”, the tuned MINI Cooper S accelerates to 62 mph from a standstill in a mere 6.6 seconds (Convertible: 6.8 seconds). Those wishing to get even more out of the acceleration can do so until the top speed of 230 km/h (143 mph) is reached (Convertible: 223 km/h; 139 mph). Likewise, pulling force is most impressive, the six-speed athlete sprinting in fourth gear from 50 to 75 mph in just 5.4 seconds (Convertible: 5.9 seconds). Fuel consumption is 8.6 ltr/100 km in the combined EU cycle (Convertible: 8.8 ltr/100 km).
As adequate braking power is equally as important as performance and sporty road-handling, John Cooper Works has provided the compact driving machine with even greater braking efficiency. The powerful sports brakes provide even better deceleration to suit the increased engine output and remain extremely stable even under the highest strain. This is achieved by means of larger brake discs, red lacquered brake callipers at the front with larger diameter brake pistons, as well as specially designed brake linings.
16-inch Bridge Spoke rims ensure that the brakes are adequately cooled and are also very stylish. Alternatively however, customers can opt for 17-inch wheels from the MINI product range.
The package includes a mechanical limited slip differential for optimal traction and safe handling even when the car is driven to its limits.
More power and performance for the MINI Cooper S.
Basis of the John Cooper Works tuning kit for the MINI Cooper S models is a new compressor that replaces the standard version and increases engine speed, thereby noticeably boosting supercharging pressure. This necessitates a vast range of further modifications to the entire MINI Cooper S engine, this being the only way to fully achieve the desired harmonized performance of the tuning kit as a whole.
For example, the air filter has an additional intake flap that opens at 4,500 rpm, ensuring that the power unit, which boasts increased compressor output, is adequately aspirated. A welcome side effect for sports-minded MINI enthusiasts: just listen to that sound! Thanks to the additional air filter flap, the acoustics of the MINI Cooper S are simply awesome.
On the other hand, an increased supercharging pressure requires optimised flow behaviour inside the cylinder head. The intake and outlet ports have been adapted to suit the modified conditions. New high-performance spark plugs, injectors with increased flow capacity and an adapted engine management system facilitate optimum fuel efficiency. Consumption is 8.6 ltr/100 km (Convertible: 8.8 ltr/100km) in an ECE cycle, a moderate figure if we consider the high performance available. It goes without saying that the EU 4 standard is complied with.
Due to an optimised rear muffler, the exhaust back pressure was also adapted to harmonize with the modification. The high-grade steel exhaust system featuring a specially designed final silencer and an awesome sound worthy of the racetrack, truly highlight this driving machine’s racing car genes. Finally, the modifications to the engine are complemented by an engine cover boasting the John Cooper Works lettering.

The engines – equipped with all special add-on parts and suspension components built according to customer specifications – are fitted at the Oxford plant. The assembly of vehicle-specific components such as the exhaust system and the brakes is then carried out –under the supervision of John Cooper Works – on the MINI assembly line at the Oxford plant
Those who have already purchased their new MINI Cooper S and later opt for John Cooper Works power tuning, can, of course, still have the kit retrofitted. Components, performance and driving fun are exactly the same. Only the additional components of this package (sports brake, limited slip differential, wheels) have to be ordered separately.
