BMW has launched a new version of its X5 xDrive45e, with this new generation PHEV offering a range of up to 54 miles on a single charge.
This figure is possible because of a new 24 kWh battery – 21 kWh usable – added to the plug-in X5. This powers an 83 kW electric motor, which works with a 286 hp straight six petrol engine to produce a combined 394 hp (290 kW) and 600 Nm of torque.
As such, the X5 is a quick SUV, completing the 0-62mph sprint in just 5.6 seconds – a 1.2 second reduction over the previous model. Despite this performance potential, the official efficiency figures come in at 27 – 44 g/km CO2 and 235.4 – 148.7 MPG, depending on specification. The electric motor’s efficiency is rated at between 23.1 and 28.3 kWh/100km.
All of the above are calculated on the WLTP test cycle, which is a fairly reliable set of results as to what is achievable in real-world driving. Looking at the NEDC figures that the previous model was tested under, the electric driving range has more than tripled.
Energy managements systems have been refined from earlier models, aiding drivers further in making the most of the electric driving potential. Familiar plug-in car systems such as regenerative braking, pre-conditioning, and charger timing are fitted.
BMW calculates that the new X5 xDrive45e has a CO2 footprint 40% smaller than that of the comparable petrol-powered X5 xDrive40i, based on average European electricity mix. When using electricity from renewable sources, that figure is reduced by as much as 70%.
