BMW has taken the wraps off the first plug-in hybrid vehicle from its core range, the X5 xDRIVE40e. BMW claims combined fuel consumption of 85.6mpg and Co2 emissions of 77g/km.
The powertrain consists of a 242bhp, 258lb/ft 2.0-litre, turbocharged four-cylinder engine and an electric motor integrated into the eight-speed automatic gearbox producing 111bhp and 184lb/ft.
Electric power comes from a 9kWh lithium ion battery mounted under the boot floor. As a result bootspace in reduced slightly down to 500 litres. The battery can be recharged from any domestic socket, or from an optional wallbox which delivers a full charge in under three hours.
BMW claims an electric-only range of 19 miles, at speeds up to a limited 75mph. With all 309bhp and 332lb/ft engaged, 0-62mph passes in 6.8 seconds, with the top speed limited to 130mph, numbers comparable to the diesel-powered X5 xDRIVE30d.
The xDRIVE40e betters its rangemate on fuel economy, though. BMW suggests a combined figure of 85.6mpg, with Co2 emissions of 77g/km. Those numbers reduce with bigger wheels and tyres.
There are three driving modes to choose from: Auto eDrive, which sorts everything out automatically; Max eDrive for electric-only; and Save Battery, which holds the level of charge at a set level for later use.
The X5’s chassis has been adapt to suit the hybrid, with standard adaptive dampers, including self-levelling rear suspension. Automatic tailgate, heated leather seats, DAB radio and satnav are all standard, as well.
The BMW X5 xDRIVE40e is due to go on sale in Autumn. Prices will be announced nearer the time.
