With a total system output of 230 kW/313 hp generated by a four-cylinder gasoline engine with BMW TwinPower Turbo technology, a synchronous electric motor integrated in the 8-speed Steptronic transmission, and a 9.0 kWh, 96-cell high-voltage Li-ion battery pack, the BMW X5 xDrive40e achieves a combined fuel consumption of 3.4 – 3.3 liters per 100 kilometers (69 - 71 mpg US) and a combined electricity consumption of 15.4 – 15.3 kWh over the same distance.

Short everyday journeys in urban areas can be completed with zero tailpipe emissions, while actual fuel consumption is reduced substantially when driving for distances of up to 25 kilometers (approx. 15 miles) in urban traffic; the BMW X5 xDrive40e is capable of consuming between just zero and 3.0 liters of fuel for every 100 kilometers in such situations (zero consumption – 78 mpg US).

On longer journeys, assuming the high-voltage battery is fully charged, daily commutes of between 50 and 60 kilometers (approx. 30 – 37 miles) can be completed in practice with a fuel consumption of no more than 6.5 liters per 100 kilometers (min. 36 mpg US), depending on driving style.
