Faster, louder and more dynamic
Technical features of the new MINI John Cooper Works

MINI UK Press Release: Motorsport is the single greatest influence in the development of the MINI John Cooper Works. In fact, the four-cylinder, common rail direct injection unit found in the standard MINI Cooper S has received the same modifications as the MINI CHALLENGE car, which is a model only licensed for track use.

Engine tuning The 2008 International Engine of the Year (1.4-1.8-litre category) found in the MINI Cooper S was a strong base unit on which to begin John Cooper Works tuning. The basic structure of the engine – a pressure die-cast aluminium crankcase with grey cast-iron liners and bed plate – has not received any modifications. Nor has the forged crankshaft or conrods.
The intake valves and valve seat rings have been upgraded with more durable materials to withstand the increased temperature caused by the free-revving engine. The pistons have had their sidewalls reinforced, which means the compression ratio is reduced to 10.0:1. The cylinder head has similarly had its wall thickness increased to reduce any localised stress or hot spots when running at peak output.


Air supply is improved through fitment of a larger air mass sensor and charge air line, meaning greater throughput of clean air and a reduction in the loss of throttle power. Induction is quickened through a larger air intake, in turn meaning the car’s maximum 280Nm torque figure is 20Nm over a standard MINI Cooper S.

At the exhaust end, a strengthened and larger twin-scroll turbocharger and exhaust manifold are central to performance improvements. The material used in machining the turbine has been upgraded for the Works engine, with maximum charge pressure increased from 0.9 to 1.3 bar. A high temperature can therefore be preserved for longer in the combustion chambers and helps the car achieve its remarkable peak torque figure.

The catalytic converter and rear part of the exhaust system are increased in size to aid the unrestricted flow and reduction in back pressure of exhaust gas, which minimises potential power loss or delay. Turbo lag is therefore virtually non-existent.

In addition, the transmission has strengthened gearing to handle the extra available power. This helps to give the car a remarkable output of 132hp per litre, yet still able to offer a staggering 40mpg.

Aural and visual pleasure is guaranteed by fitment of a John Cooper Works exhaust system. Large polished stainless steel twin tailpipes complement the deep burble produced by the Works engine and exhaust system.


Safety and chassis control

The following are standard features of the MINI John Cooper Works:

ABS Brakes EBD Electronic Brake Force Distribution CBC Cornering Brake Control EDLC Electronic Differential Lock Control DSC Dynamic Stability Control (incorporating Hill Assist) DTC Dynamic Traction Control

A first for any MINI is Dynamic Traction Control, which is an adjunct to DSC. When driving on loose gravel or snow, activating DTC improves traction by increasing the tolerance for wheel slip before DSC kicks-in. DSC will then only intervene in extreme cases. However, both DSC and DTC can be deactivated at the touch of a button and with greater slip available, even the most enthusiastic driving style is catered for!

With DSC fully deactivated, the car’s Electronic Differential Lock Control delivers an even sportier driving experience. EDLC works when the car is accelerating hard out of corners or tight bends. In this situation, it electronically slows the spinning inside rear wheel to enhance grip and ensure that all available power is transferred to the road through the wheel with greatest traction. In contrast to the way DSC and DTC manage power delivery to the wheels, EDLC does not intervene with the throughput of engine power, meaning the driver is in near total control of the handling of the car.

Customers looking for a firmer suspension than the one supplied as standard on the MINI John Cooper Works are able to specify a Sport Suspension, which stiffens the damper and anti-roll bar settings. Additionally, an even more hardcore John Cooper Works suspension which lowers the car by 10mm is available as an accessory from all MINI dealers.


Extra-large disc brakes paired with upgraded bright red Brembo performance calipers are supplied on Works cars. The front discs are 316mm in diameter. The rears are 280mm. The brake discs are approximately 22mm larger than those on a standard MINI Cooper S.

Interior and exterior styling

An array of high-quality interior features as standard in the MINI John Cooper Works includes a sport leather steering wheel, air conditioning, glossy piano black interior trim and anthracite roof lining.

Performance of the Works cars is underlined by a new speedometer, which is increased to 160mph to account for the car’s higher top speed.

A Sport button is located in front of the gear stick. When pressed it activates a bespoke engine control map producing boost earlier in the rev range and sharpening steering and throttle response. The red gear knob is unique to the MINI John Cooper Works.

Exclusive lightweight 17” light alloy wheels in Cross-spoke CHALLENGE design, shod with Run-flat tyres, feature on the Works cars. Each wheel weighs less than ten kilos.

Marking the cars out is the John Cooper Works logo, which is positioned on the boot, grille and brakes, as well as the door sills.
