Land Rover E Technology Concept
Land Rover is showcasing a catalog of innovative technologies collectively known as the e-Terrain System that are designed to reduce both fuel consumption and harmful tailpipe emissions while also improving the outstanding breadth of capability of Land Rovers SUV vehicles.
The efficient technology initiatives are all illustrated by Land_e, Land Rover's e-Terrain Technology Concept. Together, they are designed to contribute to a potential improvement in fuel economy - of up to one third over a current vehicle of similar size and performance. And many of the technologies will be available on Land Rover production models in the next few years.
The key to Land_e's importance is that it shows available and relevant technologies plus some new systems that are unique to Land Rover in the most innovative and effective way possible. It combines mechanical and electrical advances to make gains in areas ranging from transmission function to cooling efficiency, and from battery power management to power steering efficiency - all without compromising the breadth of on- and off-road capability that defines all Land Rover products.
"The e-Terrain technologies are practical, feasible, real-world solutions," says Matthew Taylor, managing director of Land Rover. "In every case, they preserve and in most cases improve our breadth of capability. We are not prepared to dilute the essence of Land Rover. But we are committed to improving fuel economy and reducing harmful tailpipe emissions."
While adhering to Land Rovers core abilities as versatile, all-terrain vehicles, the Land_e technologies target an improvement in the combined fuel economy figure for a compact SUV of up to one third. That in turn would significantly reduce harmful tailpipe emissions.
The technologies that Land_e showcases are:
Integrated Electric Rear Axle Drive
ISG Integrated Starter-Generator
Innovative Propshaft with Seamless Re-connect
Power-shift automated manual transmission
Terrain Response e-Mode
Bio-fuel capability, using bio-ethanol or bio-diesel fuel depending on engine derivative
ITP Intelligent Thermal Program
EPAS Electric Power Assisted Steering
IMES Intelligent Management of Electrical Systems
Integrated Electric Rear Axle Drive: provides electric drive alone at low speed, plus improved 4x4 ability in tough conditions. Used in conjunction with the ISG Integrated Starter-Generator system (as described below), it improves both urban emissions and off-road ability.
Land Rovers unique electric drive is different from the hybrid technology used by some 4x4 rivals. They use electric drive only to the rear axle, significantly reducing off-road capability. Integrated Electric Rear Axle Drive enhances off-road performance by augmenting rather than replacing the mechanical drive.
Off-road, the Integrated Electric Rear Axle Drive system can provide additional torque, as required. And because electric power can offer maximum torque from standstill, it is most effective from virtually zero mph. This offers better low-speed control and enhanced pull-away in difficult situations such as on slippery surfaces or when towing.
On-road, the additional low-speed torque input from the Integrated Electric Rear Axle Drive offers multiple advantages. It allows electric-powered 'traffic creep' and low-speed acceleration up to 20mph, without restarting the engine, benefiting fuel consumption and harmful tailpipe emissions. Whenever required, the ISG system restarts the engine, and the vehicle is then propelled by a combination of electrical
