At speeds of up to 50mph, the electric motor will power the car, with the combustion engine stepping in above 50mph.
Mini claims the plug-in hybrid is capable of electric driving at speeds up to 78mph with a range of up to 25 miles. The quoted performance figures are 0-62mph in 6.8 seconds, CO2 emissions of 49g/km and average fuel consumption of 134.5mpg. The standard spec for the car, which starts at £31,585 with the additional OLEV government grant of £2,500, is generous: satnav, bluetooth, cruise control, emergency e-call and six-speed Steptronic automatic transmission are all included.
The lithium-ion battery comes with a six-year/60,000 mile warranty and is the result of BMW Group's eDrive technology. The Mini Cooper S E Countryman ALL4 goes on sale on June 24th; order books are open now. For a review of the new Mini Cooper S Countryman, click here.
