MINI John Cooper Works and... Works Clubman
An expression of urban thinking with elegant panache

MINI John Cooper Works.

APN

16 January 2009.

With the MINI John Cooper Works and the MINI John Cooper Works Clubman, the BMW-owned British brand extends the range of its models in the clearly pronounced sports direction.

Both versions are powered by a 1.6-litre four-cylinder with a twin-scroll turbocharger and direct fuel injection delivering maximum output of 155 kW/211 hp.

For a MINI sized car, this means a significant amount of power, with a specific output of 132 hp per 1000cc, allowing the MINI John Cooper Works to complete the 0–100 km/h in 6.5 seconds, on the way to a top speed of 238 km/h or 148 mph.

To suit this profile, the exclusive alloy rims are particularly light and dynamic, as well as the high-performance brakes, the new exhaust system and the modified six-speed manual gearbox, all being largely based on their counterparts in the new racing version for the MINI Challenge Clubsport Series.

The engine (joint development between BMW and the French group PSA, Peugeot - Citroën) is built at the BMW Group’s engine plant in Hams Hall, Great Britain, which builds the engines for all variants within the MINI range.

Based on the four-cylinder engine of the MINI Cooper S, the engine was significantly upgraded for the MINI Challenge racing car before coming back to the road in the two new John Cooper Works production models.

Engine size remains the same at 1,598 cc, as do many technical details, but with a number of special features enhancing the engine’s power and performance, with tolerance to much higher temperatures within the combustion chamber.

Specifically, the John Cooper Works power units come with reinforced, specially polished pistons as well as a cylinder head optimised for superior strength, and a modified gasket. The intake valves and valve seat rings, are also made of a particularly resistant material.

Power is increased over the regular engine in the MINI Cooper S, mainly by optimising the supply and extraction of air and by modifying the turbocharger. The air filters, air mass meter, exhaust system and catalytic converter have likewise been modified to ensure smoothness in the intake and emission process.

The special exhaust system ends with polished stainless-steel twin tailpipes each measuring 85 millimetres or 3.35" in diameter. Appropriate modification of the exhaust system significantly reduced counter-pressure in the emission process, also complying in full with the strict EU5 (Europe) and ULEV II (USA) emission standards.

Flow capacity for feeding clean air to the turbocharger has also been increased, the twin-scroll turbocharger ensuring a particularly spontaneous build-up of power.

A turbine made of a special, top-grade material has been developed for the power unit, with maximum charge pressure increased from 0.9 to 1.3 bar.

Peak torque of 260 Newton-metres or 192 lb-ft comes at an engine speed of 1,850 rpm, reaching 280 Newton-metres or 206 lb-ft when accelerating by briefly increasing charge pressure in the speed range between 1,950 and 5,500 rpm, with the overboost function for even more dynamic acceleration.

The direct response comes out with the MINI John Cooper Works completing the 0–100 km/h in 6.5 seconds, and 6.8 seconds for the equivalent Clubman model. Top speed is the same for both models: 238 km/h or 148 mph.

Considering their performance, both versions of the John Cooper Works remain fuel-efficient thanks to the common-rail direct fuel injection with its precise dosage of fuel, and other energy-saving technologies.

The MINI John Cooper Works consumes 6.9 litres/100 kilometres, ( 34.0 U.S. mpg, 40.8 imperial mpg), in the EU test cycle, the Clubman equivalent taking slightly more with 7.0 litres/100 kilometres (33.5 U.S. mpg, 40.2 imp. mpg). The CO2 ratings, are respectively 165 and 167 grams per kilometre.

Both John Cooper Works versions come with a six-speed manual gearbox modified in its features and components to match the high torque of the top-of-the-range engine.

Precise handling is also helped by the Electric Power Steering (EPS) of the MINI, with steering assistance adapted to road speed. The driver can manoeuvre and park the car with minimum effort, then, steering forces increase gradually with higher speeds to enhance safety and driving precision. The electromechanical steering is significantly lighter than a conventional system and operates only when required in order to save energy.

The electromechanical steering system also enables the driver to program different set-ups. In the basic setting, EPS provides a balanced power assistance as a function of road speed. Pressing the Sports Button (standard on both MINI John Cooper Works versions) next to the gearshift lever on the centre console, the driver activates a more dynamic control map providing higher steering forces and more steering precision. In the same time the Sports Button also switches over the gas pedal control map to a faster engine response with higher sporting performance.

Suspension, brakes and wheels - With the low centre of gravity, the MINI front axle features McPherson spring struts, while the centrally guided rear axle enhances road contact at all times, particularly in dynamic driving.

Both the MINI John Cooper Works and the MINI John Cooper Works Clubman come as standard with a sports-tuned suspension. Alternatively, a sports suspension option features even firmer dampers and stronger anti-roll bars on the front and rear axle.

A special John Cooper Works suspension featured as special equipment for extreme racing requirements lowers the entire car by 10 millimetres or almost 0.4", and features even firmer dampers and anti-roll bars with a larger diameter than on the sports suspension.

The standard sports brake system features fixed-calliper disc brakes with their aluminium callipers finished in red, inner ventilation on the front discs and presenting the John Cooper Works emblem on the callipers. They are extra-large to enhance brake power, and are based in their design and response on the brake system featured in the MINI Challenge racing cars.

The same applies to the exclusive 17-inch light-alloy wheels in John Cooper Works Cross Spoke Challenge Design. Each of them weighs less than 10 kg or 22 lb.

The high-speed tyres (205/45 W 17) allow the driver to continue even under a complete loss of tyre pressure to reach the nearest workshop. Both the MINI John Cooper Works and the MINI John Cooper Works Clubman come with a tyre pressure monitoring system.

Both John Cooper Works versions come standard with ABS brakes, EBD Electronic Brake Force Distribution, CBC Cornering Brake Control, and DSC Dynamic Stability Control with hill start-off assistance and DTC Dynamic Traction Control.

DSC prevents the car from swerving out of control over its front or rear wheels, DTC allows controlled slip on the drive wheels (front), and the Electronic Differential Lock Control applies the brakes appropriately on a drive wheel spinning in a tight bend, to enhance traction without a negative influence on the steering behaviour. More on these technologies in the MINI - Technologies section.

Inside, the three-spoke sports steering wheel is in leather, the roof lining in Anthracite and the interior surfaces in glossy Piano Black. The speedometer extends all the way to 260 km/h or 160 mph.

The range of equipment and accessories available for the new John Cooper Works versions is naturally inspired first by motorsport, with the appropriate safety standards to go with.

MINI offers a wide choice through the various features available, from the range of paintwork colours, interior trim options, seat upholstery, interior colours and trim variants, to the comfort features and other special equipment offered by both MINI and John Cooper Works for comfort, practical qualities or elegant panache.
