The G05 BMW X5 will add a plug-in hybrid variant next year with the advent of an X5 xDrive45e variant, the entry into the hybrid segment being made with six-cylinders instead of four. Under the bonnet is a 286 hp inline-six turbocharged petrol engine, paired with an electric drive system offering 112 hp for a total system output of 394 hp and 600 Nm.

The upcoming X5 hybrid will take over from the F15 X5 xDrive40e, which offers a combined 313 hp and 450 Nm of torque from its N20 turbo inline-four and electric motor. Performance-wise, the outgoing F15 xDrive40e managed 0-100 km/h in 6.8 seconds and a 210 km/h top speed, but the G05 xDrive45e is faster, doing the 0-100 km/h run in 5.6 seconds and having a top speed of 235 km/h. Combined fuel consumption is 2.1 L/100 km, and CO2 emissions is rated at 49 g/km.

Its performance on pure electric drive has been improved. The G05 X5 xDrive45e will be able to cover more ground on electric power alone – provisional numbers indicate an 80 km operating range supposedly calculated based on the new WLTP test cycle, well up from the 30 km (NEDC) range of the F15 xDrive40e. Top speed in electric mode has also increased to 140 km/h, up from 120 km/h on the F15 model.

An eight-speed automatic transmission sends drive from both engine and electric motor to all four corners via the automaker’s xDrive all-wheel-drive system, while the high-voltage battery is located in the X5’s underbody section, which gives the xDrive45e a lower centre of gravity compared to its conventionally powered, internal combustion siblings.

No details on the battery pack and technical aspects of charging as yet, but the company says that packaging for the battery sees a 150-litre reduction in capacity for the luggage compartment, making cargo space 500 litres on this one with all seats in place. Folding down the rear seat backs will give a total luggage capacity of 1,716 litres, while the fuel tank will hold 69 litres of petrol; this appears to be reduced from the F15 xDrive40e’s 85-litre fuel capacity.

On the chassis side, the G05 xDrive45e is equipped with air suspension and electronically-controlled dampers for both front and rear axles, while integral active steering is optionally available. New digital services geared specifically towards electromobility will be offered for the plug-in hybrid SAV as well, says BMW. Market launch for the X5 xDrive45e will take place “in the course of 2019”, the company noted.
