Land Rover says a diesel-hybrid SUV based on the Range Rover Sport, the middle-size model of three Range Rovers currently on sale in the UK, will be built from 2013.
A plug-in diesel-hybrid model will also be sold with a release date set after the launch of the standard diesel-hybrid model.
The Range_e, as it is known, is a prototype at the moment and was first revealed at the Geneva Motor Show in 2011.
Based on the Range Rover Sport, it comes with four-wheel drive and the luxury and equipment typically associated with Land Rover’s ultra-luxury sub-brand.
The Range_e will offer a 245ps 3.0-litre V6 diesel engine and a 69kW electric motor. An eight-speed automatic gearbox and regenerative braking is also offered with the new 4×4.
Land Rover says the new Range_e hybrid will deliver CO2 emissions under 100g/km, making it the first ever Land Rover to offer such a low figure and ensures it falls into the lowest band of UK road tax.
Fuel economy is predicted to be somewhere in the region of 85g/km – again a record for a Land Rover car – and a range of 690 miles has been suggested by Land Rover.
In plug-in diesel-hybrid variation, Land Rover says the Range_e will offer 20 miles of all-electric driving from a four hour charge and says this will cost just £1.
However, before the two new models are launched Land Rover is undertaking a strenuous testing programme, including investigating the performance of the hybrid system when wading through water.
The current Range Rover range includes the standard Range Rover, the smaller Range Rover Sport and the new Range Rover Evoque, the smallest, lightest and greenest Range Rover on sale and the only model to offer a two-wheel drive option.
Range Rover cars can be bought from dedicated Range Rover dealerships such as Rocar Moores Land Rover of Huddersfield and Copley Land Rover of Halifax.
