Mini cleans up its act

Minis clean up

Mini today announced it will fit many of the Efficient Dynamics tech already seen on the 1-series to all new hatchbacks fitted with the new PSA engines. The result? A Cooper D will now emit just 104g/km of CO2 - matching the signficantly more expensive Toyota Prius. And average fuel consumption on the diesel climbs to 72.4mpg - around eight miles further than before - to beat even the petrol-electric Prius.

The technical lowdown

Mini is fitting the following equipment to every hatchback it sells from August: • Stop-start function to cut the engine at standstill when neutral is selected • Intelligent alternator which charges the battery only under coasting or braking; it no longer drags power for continuous charging • Gearshift indicator to advise when to change up The convertible won't benefit from the efficiency measures, as it still uses the old Chrysler-derived 1.6, rather than the new BMW-PSA developed 1.6. The new engines are expected in the soft-top in the next couple of years, however - and they'll probably pop up in PSA and Ford group products, too.
