Mini Asia and British United Automobiles announced the availability of the new Mini John Cooper Works Clubman and the new John Cooper Works Countryman. Here’s the news from Mini:
With the concentrated power of their new engine and its optimised ability to transfer its output onto either a road surface or loose terrain, the new John Cooper Works Clubman and the new John Cooper Works Countryman have assured their places in the leading line-up of sport models in the premium compact segment.
In both models, a new 8-speed Steptronic sports transmission is fitted as standard, including mechanical differential lock on the front axle, an ALL4 all-wheel drive system, a specifically engineered chassis, and additional reinforcement modifications for the body structure, engine connection and chassis fastenings. This enables the John Cooper Works racing sensations to attain a completely new dimension of performance.
Both the individual six door model with its extreme driving fun and the robust all-rounder provide a challenging performance experience. The latest generation of the 4-cylinder engine developed for the John Cooper Works models with Mini TwinPower Turbo technology surpasses that of the previous drive by as much as 75 hp at maximum output. Maximum torque has increased by 100 Nm to 450 Nm, and acceleration performance has also risen commensurately. The new John Cooper Works Clubman turns in an acceleration of 0 to 100 km/h in 4.9 seconds, with the new John Cooper Works Countryman achieving the same in 5.1 seconds – 1.4 and 1.5 seconds faster than in the previous models respectively.
Highlights of the new models are:
- New 4-cylinder engine with MINI TwinPower Turbo technology and 306 hp with 450 Nm.
- Increase in output compared to the previous models: 75 hp
- Cooling concept incorporates know-how from the race track
- New exhaust system with remarkable sound development
- LL4 all-wheel drive as standard
- New 8-speed Steptronic sports transmission with integrated mechanical differential lock for the front wheels
- Model-specific chassis design and coordination
- New bigger John Cooper Works sport brake system
- Extremely rigid body structure, motor connection and chassis fastenings
- New adaptive LED headlights with Matrix high beam function and LED rear lights in Union Jack design
Maximum output from four cylinders: New 2.0 litre engine with MINI TwinPower Turbo technology.
As the power source for extreme driving fun, the comprehensively redesigned 4-cylinder engine has been consistently oriented towards maximum output. The 4-cylinder engine has been completely redesigned to deliver maximum performance thanks to model-specific modifications to the crankshaft drive 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, with a reduction in compression ratio 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 fine vaporisation enables precise metering of the fuel, which makes for especially clean combustion in addition to enabling optimum efficiency. 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).
The high-performance drive of the new John Cooper Works Clubman and the new John Cooper Works Countryman generates a maximum torque of 450 Nm in the broad engine speed range between 1,750 and 4,500 rpm, which is around 29 percent higher than that of the previous engine. The maximum output of the new 4-cylinder engine has been increased by approximately 32 percent. The new top level of 306 hp is reached between 5,000 and 6,250 rpm. The resulting
pulling power enables the new engine of the John Cooper Works Clubman to produce an acceleration performance of 0 to 100 kph in 4.9 seconds, while the figure for the new John Cooper Works Countryman is 5.1 seconds. For the first time with Mini vehicles, the maximum speed of the new top sports performer is now electronically limited to 250 kph.
Speed burst manoeuvres are accompanied by the striking sound of the newly developed, model- specific sport exhaust system. The extreme output of the engine makes itself more intensively felt than ever before, with an emotionally charged acoustic design that matches the load requirements while underlining its performance character. The twin exhaust system leads into a new, particularly large-volume rear silencer – with its low level of exhaust back pressure, this benefits the engine’s spontaneous power delivery. The external diameter of the tailpipe trims integrated in the right and left of the rear apron is 95 millimetres for the new MINI John Cooper Works Clubman and 85 millimetres in the new John Cooper Works Countryman.
8-speed Steptronic sports transmission, mechanical differential lock
The transverse-mounted front engine in both of these extreme sport vehicles transmits its phenomenal power to the 8-speed Steptronic sports transmission. The latest generation of the transmission features enhanced internal efficiency and an extended steering axis inclination – this contributes to lower engine speeds when driving in a higher gear, which in turn translates to lower fuel
consumption. A new transmission control increases both the gear shift dynamics and driving comfort, and shift paddles are mounted as standard on the steering wheel for manual gear selection. Moreover, the 8-speed Steptronic sports transmission offers Launch Control for accelerating from standing with optimum traction and maximum dynamics.
The new automatic transmission also features an integrated differential lock – it functions transversely to reduce the speed compensation between the front wheels. Under load conditions, this means that a locking effect of up to 39 percent can be generated. The mechanical differential lock is interconnected with the Dynamic Stability Control (DSC) system, which aids both the traction of the new John Cooper Works Clubman and the new John Cooper Works Countryman in all road conditions, as well as the driving dynamics when taking bends with a sporty driving style. The differential lock supports the vehicle’s agility when changing direction quickly or accelerating dynamically out of a bend, by applying targeted shifting of the drive torque.
