KEY POINTS:
The Second-Generation Mini is set to receive a number of high-tech engine tweaks later this year.
Available as a package across the range will be brake energy regeneration, an auto stop-start function and switch point display.
Brake energy regeneration works via an intelligent alternator control (IAC) and anabsorbent glass mat battery to recycle previously lost energy, which saves fuel.
The IAC reduces drag on the engine by only engaging when required to charge the battery, whereas a traditional alternator is always pulling power from the engine. Additionally, the energy generated by the engine on over-run (under braking or descending a hill) was previously wasted - now this lost energy is utilised by the IAC to charge the battery.
The auto start-stop function, available with manual transmission cars, automatically switches the engine off when the vehicle is stationary and the driver puts the car into neutral.
To restart the driver only need engage the clutch again before pulling away in the normal manner.
The system may be de-activated at the touch of a button when not required.
Both the regeneration and start-stop functions are similar to the technology employed by vehicles.
Switch point display aids drivers of manual transmission cars in selecting the most economical gear in which to drive.
The engine management system analyses speed, road situation and accelerator pedal position and based on this data calculates optimum gearing. The ideal gear is then displayed by number in the cockpit display.
The changes are claimed to improve the overall economy of the Mini Cooper by 6.9 per cent, and turbocharged Cooper S by an impressive 10.3 per cent.
