BMW has revealed two plug-in hybrid versions of its 7-series luxury model ahead of their arrival this spring.

The models are powered by the firm’s 286hp 3.0-litre petrol model which is mated to an electric motor that produces 113hp.

Two variants are offered – a rear-wheel-drive only version (badged 745e) and a four-wheel-drive version (badged 745Le Xdrive).

According to BMW, the rear-wheel drive model has an electric-only range of 34-36 miles; this drops to 32-34 miles in the all-wheel-drive offering.

The RWD model emits 48g/km of CO2 and returns up to 141mpg while the AWD model emits 52mpg and returns up to 118mpg.

7series plug-in

The motor is located underneath the rear seats – as opposed to being underneath the boot like in some PHEVs – but BMW said bootspace is still “only slightly restricted” owing to its placement.

When charging the battery, the driver can see information in the instrument panel, such as charge level and duration, charging current, currently available electrical range and the chosen conditioning level, while from the summer BMW is introducing a new digital service which aims to simplify charging on the move.

When selecting a public charging station, the navigation system will also provide the driver with a list of recommended nearby hotels, restaurants, cafes and tourist attractions while a charging station occupancy forecast is also being provided, BMW said.

The RWD version will cost from £76,815 and the AWD model from £83,560.
