's Range_e, a plug-in hybrid diesel-electric powertrain concept, has been crowned as the Automotive Innovation for 2011 by the Society of Motor Manufacturers and Traders in the UK (SMMT). The concept was first shown at the Geneva Auto Show last March. It is powered by a plug-in hybrid system with an overall CO2 output of 89 g/km and 85mpg. The hybrid system made up of a 3.0-liter 245hp TDV6 diesel combined with a 93hp electric motor powered by a 14.2 kWh lithium-ion battery.
The Range_e can be driven more than 20 miles on its electric power alone and its maximum range is 690 miles. The diesel hybrid drivetrain engages seamlessly as the system's combined 339hp delivers a top speed of around 120mph. Battery recharging can be accomplished simply and efficiently by connecting the system to an external 240V power source. The Range_e is engineered with the same full-time 4WD capability as the standard Range Rover Sport, with high and low range in the transmission, front and rear differentials and a mechanical locking center differential.
Dependent on the driver's demand, the car's 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 to capture energy usually wasted in heat energy via the brakes. This energy can then be redeployed to drive the vehicle, further reducing fossil fuel consumption.
