It’s called the Range_e, and the advanced plug-in hybrid diesel offering is Land Rover’s debutant at the Geneva Motor Show.

The Range_e is based on the Range Rover Sport and uses the current 242 hp 3.0 litre TDV6 diesel engine, working with an eight-speed ZF automatic transmission and a 69 kW electric motor. The combined maximum output is 335 hp and the vehicle has a 193 kph top speed. Land Rover says that the SUV can achieve 85 mpg, or 3.36 litres per 100 km, and 1,112 km will be possible on a full tank of fuel.

Using a parallel hybrid system, with a 14.2kW/h lithium-ion battery that can be recharged from an external 240V power source, Range_e can be driven on electric power alone for around 32km. A full recharge from a standard domestic power supply can be accomplished in around four hours.

The Range_e comes with the same full 4WD capability as the standard Range Rover Sport, with high and low range in the transmission, front and rear differentials and a mechanical locking centre differential. Dependent on the driver demand, the system decides the most efficient method to deliver the power required, whether this is by electric, diesel or both. The Range_e also features regenerative braking.

Land Rover expects the development version’s powertrain to become available in future production models, following the scheduled launch of its diesel-electric hybrid in 2013. Thus far, fleet trials with five Range_e vehicles have covered more than 19,000 km since last December.
