BMW has added a plug-in hybrid variant to its X3 SUV line-up as part of a wider push to introduce new PHEVs to its model line-up and update existing variants.

Called the X3 xDrive30e, its plug-in hybrid drivetrain comprises a 2.0-litre four-cylinder petrol engine combined with an electric motor resulting in a total output of 252hp, while it is also equipped with XtraBoost, an on-demand performance system that increases the power output of the hybrid-drive system by 41hp.

BMW said the model has an all-electric range of up to 34 miles and offers a combined economy of 128.4-117.7mpg along with CO2 emissions of 49g/km.

The German brand added the battery has been located under the rear seat to help save space and minimise the loss of luggage space associated with having the battery. It said the X3 PHEV offers 455 litres of boot space, down from the 550 litres offered on normal variants.

BMW said production of the model will commence in December, adding an all-electric X3 will debut in early 2020, although the company has not provided any information about the electric model at this stage.

The new plug-in hybrid X3 joins the larger X5 xDrive45e and will sit alongside other low-emission BMW SUVs when the X1 xDrive25e is launched early next year as the seventh plug-in hybrid offered by BMW.

Other models on offer are the 330e, 530e and 745e saloons and the 225Xe Active Tourer.
