Land Rover will introduce plug-in hybrid technology in its larger vehicles in 2013.

The technology was previewed in the Range_e concept on display at the Geneva Motor Show.

Based on the Range Rover Sport, the model uses that car's 245bhp 3.0-litre V6 diesel engine as well as a lithium-ion battery that can provide up to 20 miles of emissions-free travel from a plug-in charge.

Using current fuel consumption test cycle, the model produces an equivalent of 89g/km of CO2 and fuel consumption of 85mpg on the combined cycle.
