The 2018 Range Rover Sport will become the first model in Jaguar Land Rover's range to be available as a plug-in hybrid, offering CO2 emissions of 64g/km.

The P400e model, priced from £70,800, combines a 300PS 2.0-litre petrol engine with an 85kW electric motor.

It will have a total available power output of 404PS and will emit 64g/km of CO2 on the NEDC cycle. It will offer an all-electric range of 31 miles and official combined fuel economy of 101mpg.

The P400e's default driving mode will be 'parallel hybrid mode'. This will combine petrol and electric drive, and the driver can optimise battery carge or fuel economy by using one of two charge management functions:

• Save function, which prevents the battery charge dropping below the selected level, or
• Predictive energe optimisation function, where entering a destination in the navigation system utilises GPS data to optimise the switch between electric motor and petrol engine to maximise fuel economy over gradients along the route.

EV (electric vehicle) mode will enable the vehicle to run solely on battery power.

Nick Collins, vehicle line director at Jaguar Land Rover, said: "The new Range Rover Sport strikes a compelling balance between dynamic capability, passenger comfort and efficiency. The introduction of our advanced plug-in hybrid powertrain is a watershed moment in the history of our performance SUV.”

The motor is powered by a 13.1kWh high-voltage lithium-ion battery which, through rapid charging, can be fully charged in two-and-three-quarter hours.

It can be fully charged in seven-and-a-half hours using the 10 amp home charging cable supplied as standard.

Today’s reveal follows the news that from 2020 all new Jaguar and Land Rover vehicles will have the option of electrification .

In addition to the new petrol-electric hybrid options, other engine options cover Ingenium four-cylinder, V6 and V8 petrol and diesel units

The new range, which is available to order now with first deliveries taking place early next year, also offers styling changes and technology updates such as enhanced in-car connectivity and a new infotainment system.
