Come August, the European MINI range will undergo a revamp that results in fuel economy and emissions improvements across the board. The most impressive numbers come from the Cooper D (for diesel), which as you know is unavailable here. We'll use the car's US mpg measurements for the sake of discussion (the press info after the jump uses measurements based on the larger Imperial gallon). The current Cooper D gets 53.4mpg as is, but after the changes it'll jump to a tick over 60 mpg. At the same time, its CO² emissions will drop from 118g/km to 104g/km.

As you'll see after the jump, every car makes, including the Cooper S, whose combined-cycle fuel economy will rise to almost 38 mpg. The regular MINI Cooper will go 43 miles on a single gallon, and the Europe-only MINI One will do slightly better, getting 44 and change. MINI pulls this off by incorporating regenerative braking, a driver-defeatable stop/start system on manual-transmission-equipped cars, and by adding a shift indicator that tells the driver what gear to select to ensure that maximum efficiency is being achieved. We see no reason why these changes couldn't be incorporated on the USDM Cooper and Cooper S, and hope that 's part of the plan. Next step: work on getting that Cooper D over here, okay? We want that.

Full PR with before-and-after numbers is pasted after the jump. You can use TDIClub's conversion calc to translate the Imperial measurements to our own.

MINI hatches plan to clean up with revised engine range

MINI hatch models are to receive technological revisions later this year, resulting in jaw-dropping performance and efficiency figures. Already BMW Group's cleanest ever car, the MINI Cooper D will be capable of returning an astonishing 72.4mpg, with CO 2 emissions of just 104 g/km.

When production of the revised models begins in August 2007, there will be no requirement for alternative fuel sources or hybrid technology to achieve these stunning stats. All model variants will instead be supplied as standard with high-tech engine tweaks, providing exceptional economy and minimal emissions without compromising the MINI driving experience.

Efficiency improvements are consistent across the revised MINI hatch range.

Brake Energy Regeneration, Auto Start-Stop Function and Switch Point Display complete a package that will come at no extra cost to future MINI customers.

Brake Energy Regeneration works by using an Intelligent Alternator Control (IAC) and an Absorbent 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.

Switch Point Display aids drivers of manual transmission MINIs 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.

Even without these technology advancements in place, MINI leads the new car market for year-on-year improvements in clean engine manufacturing. CO 2 output per car has been reduced in the last year by an impressive 14 per cent. Putting that into perspective, the industry average was recorded at a lowly 0.3 per cent.*

To put the icing on the cake for customers, MINI Cooper D owners will continue to benefit from the car falling into VED tax band B. So savings are not only made in carbon emissions, but at the fuel pumps and the Post Office when replacing an annual road fund licence too. Little wonder then that MINI UK is again celebrating a month of record car sales!**
