MINI Cooper D: Technology Highlights

The MINI Cooper D’s brand new turbocharged diesel engine develops 110hp at 4,000rpm. Under normal conditions peak torque of 240Nm is achieved between 1,750 and 2,000rpm.  Deploying the engine’s Overboost function gives the Cooper D an additional 20Nm of torque, meaning the driver will experience 260Nm at 2,000rpm.  MINI enthusiasts will recognise this torque figure is identical to that produced by the new MINI Cooper S.

The turbocharger system features variable turbine geometry, ensuring optimum smoothness, efficiency and response even at low engine speeds.

Second-generation common rail diesel technology operating at a maximum pressure of 1,600 bar is key to the new diesel engine’s combustion process. Additionally, refinement is achieved using a precise multiple-injection process for each operating cycle.  The combustion chambers have been optimised in their shape and dimensions to prevent unwanted turbulence and maintain a smooth and consistent combustion process at all times.

A diesel particulate filter almost eliminates diesel exhaust emissions and helps to make the MINI diesel engine one of the most environmentally friendly engines in its class.

Six-speed gearbox as standard

The new MINI One and new MINI Cooper D both come as standard with a six-speed manual gearbox.  Dynamic acceleration is a result of the precise shift control provided by carbon friction plates and helical gears operating within an optimised syncromesh.  With its long transmission ratio, the sixth gear allows optimum fuel economy, even at high speeds.

The MINI One will be available to customers with the option of a six-speed automatic transmission.  A key feature is the Steptronic function, which allows the driver to shift gears in sequence using the gear lever or the standard-fit paddles on the steering wheel.  For keener drivers, a Sports Button is available as an option for even shorter gearshift times and faster throttle response.

Design highlights

Features including a black finish to the car’s radiator grille bars, door mirrors and tailgate handle are exclusive to the MINI One. The new MINI Cooper D’s sporting prowess is underlined by the addition of a pronounced power dome on the car’s bonnet. A discernibly larger air intake than on other MINI models features on the Cooper D, as does a crossbar in body colour on the lower intake.

Chassis and suspension

The go-kart driving experience is enhanced in the new MINI One and Cooper D through a new suspension set-up, as introduced on the MINI Cooper and Cooper S. MINI is the only car in its segment to be fitted with a central-arm rear axle featuring elaborate kinematics for optimum tyre-to-road contact.

Electrical Power Assisted Steering (EPAS) incorporating modern mechanical control gives the driver increased precision feedback. Variable power assistance dependent on speed ensures MINI drivers are guaranteed an involving drive every time they step into the car.

The new MINI Cooper and Cooper S went on sale in the UK on 18 November 2006.  By the end of the year, close to 7,000 orders were taken for the new models.  With sales looking strong into the New Year and the launch of the new MINI Convertible Sidewalk taking place in the spring, MINI is set for another great year at home on British roads.
