Land Rover introduced the Range_e at the 2011 Geneva Motor Show, proving how it remains committed to creating vehicles that are more fuel and emissions-efficient. The development model features an advanced plug-in hybrid diesel-electric powertrain that may be used in future production models, following the scheduled launch of Land Rover’s diesel-electric hybrid in 2013.
Range_e is based on the Range Rover Sport and it is powered by the current 245PS 3.0-litre TDV6 diesel engine, working with an eight-speed ZF automatic transmission and a 69kW electric motor.
Range_e uses a parallel hybrid system, with a 14.2kW/h lithium-ion battery that can be recharged from an external 240V power source. The vehicle can run on electric power alone for over 20 miles (32km), with zero harmful tailpipe emissions.
It can be fully recharged from a standard domestic power supply in about four hours. The average European car driver covers less than 25 miles (40km) a day. This means that the EV range offered by this technology will support the majority of short urban journeys, where fuel economy and emissions are the main concern.
But for longer journeys, the diesel hybrid drivetrain will engage and this continually optimizes CO2 emissions. The Range_e has overall CO2 emissions of only 89g/km but it has a maximum system output of 339PS and a top speed of about 120mph (193kph), offering a fuel economy of 85mpg (3.36 l/100km).
Because of the improved fuel efficiency from the hybrid system, driving 690 miles (1,112km) is possible on a full tank of fuel. Range_e is also engineered 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.
Depending on the driver demand, the car's intelligent system chooses the most efficient method to deliver the power, whether by electric, diesel or both. The Range_e has also been equipped with regenerative braking to capture energy that’s mostly wasted in heat energy via the brakes. To drive the vehicle, this energy can then be redeployed, further lowering the fossil fuel consumption.
