Land Rover's ongoing commitment to building vehicles that are more fuel efficient and emissions, reached another milestone in the Geneva Motor Show 2011 with the first presentation of Land Rover Range_e. This development model is equipped with an advanced plug-in hybrid diesel-electric propulsion system that Land Rover plans to make available to future production models, following the planned launch of its diesel-electric hybrid in 2013.
Land Rover Range_e is based on the Range Rover Sport and uses the current 3.0-liter 245PS TDV6 diesel engine, working with a ZF gearbox with eight-speed automatic and a 69kw electric motor. The use of a parallel hybrid system with a 14.2kW / h lithium ion can be recharged from an external power source 240V, Range_e Land Rover can be driven on electric power alone for more than 20 miles with zero emissions of gases harmful exhaust.
At full load, normal household power supply can be implemented in about four hours. Typically, the majority of European drivers cover less than 25 miles a day and that is why EV range offered by this technology supports most of the city for short trips, with fuel economy and emissions are of primary importance. However, for long journeys will take the hybrid diesel engine and continuously optimize emissions of CO2.
Overall CO2 emissions are just 89g/km, but Land Rover Range_e has a maximum power of 339PS system and a top speed of around 120 kilometers per hour, with fuel economy of 85mpg. Improving the energy efficiency of the hybrid system can be 690 miles on a full tank of fuel.
Land Rover Range_e is also designed with the 4WD total same as the standard Range Rover Sport, the transmission range of high and low, front and rear differentials and a mechanical limited slip center differential. Depending on the request of the driver, the smart car decide the most effective way to maintain power, whether by electricity, diesel or both. The Range_e also regenerative braking to capture energy normally lost as heat through the brakes. This energy can be reassigned to drive the vehicle, further reducing consumption of fossil fuels.
John Edwards, director of global brand Land Rover, said. "This system is the first example of a premium plug-in hybrid that also provides full four-wheel drive ability, as you would expect from a Land Rover is a further development of production technology for diesel- electric hybrid, which will be launched in the next generation of SUVs and will be available to customers over the next two years. "
Land Rover in partnering with cable
Land Rover Range_e is one of a series of projects supported by the Board of Land Rover UK Government Technology Strategy and five models are currently testing a prototype program with colleagues Land Rover wired - Coventry and Birmingham demonstrators low emissions - a consortium. Land Rover early indication of the hybrid system was launched in the near future, after the debut of the first standard for diesel-electric hybrid models in 2013.
Pete Richings, Hybrid chief engineer, said: "We started the test fleet Range_e in December 2010 and so far we have covered 12,000 miles at the trial of five test vehicles, we collect valuable data in the world Real will allow us to refine the technology. before establishing a production vehicle. "
Land Rover will continue to recognize the need to work with all the CO2 footprint, such as to reduce weight, reduce mechanical losses and increase the efficiency of power transmission, and our hybrid technology is part of the research and development the trip.
Jaguar, Land Rover is committed to spend £ 800,000,000 environmental technology and has targeted 25 per cent discount on its fleet average CO2 emissions between 2008 and 2012.
