BMW has added a plug-in hybrid engine to the new X3 and revealed more details about the new 330e.
It has also showcased the X5 and 7 Series plug-in hybrids, which feature a new six-cylinder petrol engine and fitted larger batteries to its existing plug-in hybrid models.
The X3 xDrive30e will commence production at the end of the year. It will use a four-cylinder petrol engine and electric motor, providing 252PS with a 41PS over-boost feature.
CO2 emissions from the SUV will be 56g/km and the car will have a 31-mile electric range.
The 330e uses the same powertrain but is more efficient, emitting just 39g/km of CO2. It will cover 37 miles on the battery alone and provides acceleration from 0-62mph in six seconds.
In the X5 xDrive45e, the electric range is 49 miles and CO2 emissions are 49g/km.
The 745Le uses the same new six-cylinder engine, emitting from 48g/km of CO2 and providing a zero-emission range of around 30 miles.
Both vehicles develop 394PS.
Upgrades to the batteries in the existing BMW 530e and 225Xe Active Tourer see further improvements in range and emissions.
The 530e now emits from 44g/km and can cover 39 miles on a single charge.
The 225Xe emits from 43g/km and has a 35-mile range.
