Range Rover has cleaned up its act with a hybrid prototype version of its latest Range Rover Sport. The new car is one of a number of eco-friendly solutions that the firm is evaluating as it bids to shake-off its gas guzzler image.

Under the bonnet, the Range_e features Jaguar-Land Rover’s latest TDV6 diesel, connected to the eight-speed ZF automatic gearbox as fitted to the Range Rover TDV8. The plug-in parallel diesel hybrid system means that the Range_e’s carbon dioxide emissions fall to 89g/km. The Range Rover Sport on sale now with the TDV6 engine emits 243g/km.

The Sport’s EV range is 20 miles, and the batteries can be recharged from a household plug, while top speed is 120mph. The firm claims that the car has a total range of 690 miles.
