MINI Clubman JCW Model Now Comes with 306 HP

MINI took the veils off its facelifted Clubman model today and, in a surprising move, focused most on the John Cooper Works model. It's a surprise, by all means, but when you learn about all the cool new stuff happening under the sheet metal, you start to understand why this approach was taken.

The new Clubman is one of the most powerful road-legal models the company ever made. It now comes with an 8-speed automatic gearbox and all-wheel drive ALL4 as standard. There's a mechanical locking differential included on the front axle, while the specifically engineered chassis, and additional reinforcement modifications for the body structure, engine connection and chassis fastenings are meant to enhance the car beyond belief.

The new MINI John Cooper Works Clubman turns in an acceleration of 0 to 100 km/h in 4.9 seconds, which is 1.4 seconds faster than the old model. Admittedly, the older car lacked some 75 HP and 100 Nm of torque, the new one making 450 Nm in total. To keep things tidy, a new braking system was developed as well, while the exhaust now has an OPF but still manages to sound good according to MINI.

The engine is based on the 2-litre drive from the MINI Cooper S Clubman but has now undergone model-specific modifications to the crankshaft drive and also benefits from the latest generation of MINI TwinPower Turbo technology. These modifications are based on the John Cooper Works’ racing know-how and comprise a reinforced crankshaft, a main bearing with an extended cross-section, specific pistons, connecting rods, and a new vibration damper with optimised cooling.

The considerably increased output compared to the previous engine is also helped along by the bigger turbocharger. The compression ratio of the new engine has been reduced from 10.2 to 9.5 to match the increased system charging pressure. In addition, the turbocharger integrated in the exhaust manifold is fitted with a blow-off valve that contributes to its optimised response characteristics. The air intake duct has also been redeveloped and dethrottled as far as possible. The spontaneous power delivery in the engine is also supported by the latest generation of direct petrol injection. Its new multi-hole fuel injectors arranged between the valves enable an increased flow rate, transporting the fuel to the combustion chambers under an injection pressure of up to 350 ba. The fine vaporisation enables precise metering of the fuel. The MINI TwinPower Turbo technology also includes fully variable valve control along the lines of the VALVETRONIC system patented by the BMW Group, as well as variable camshaft control on the intake and exhaust sides (double VANOS).
