E-Terrain Technologies
e_Terrain Technologies are the industry leading advancements in sustainable engineering that have been central to Land Rover development for years now. Electric Rear Axle Drive (ERAD), Crank Integrated Starter Generator (CISG) and a Diesel Hybrid engineering evaluation vehicle, which is part of a joint research project between Land Rover and the UK Government’s Energy Saving Trust, are just some of the things we’ve developed.
These advances in technology are brought together in new models that maintain the balance between performance in some of Our Planet’s most challenging environments, while continuously striving to protect them. Diesel ERAD Hybrids incorporate Land Rover’s award-winning Terrain Response system, which helps the driver maintain unsurpassed all-terrain performance together with the advantage of reduced emissions from the hybrid technology.
Here’s the low-down on the amazing e-Terrain Response technology.
There are five basic programme modes: Eco; Dynamic; Grass/Gravel/Snow; Mud and Ruts; Sand.
The Eco Programme is used for much of the normal driving cycle, allowing the vehicle to select electric or diesel power depending on the driving conditions. At low speed, the diesel engine is automatically switched off and the ERAD drives the rear wheels, producing absolutely no exhaust emissions.
The Dynamic Programme is designed for open road, steady-speed use, where moderate acceleration is required.
The diesel engine drives the front wheels, with the engine mapping optimised for maximum fuel economy. Four wheel drive traction is available instantaneously, with the engine and electric drives working together to optimise power and torque delivery.
The Grass/Gravel/Snow Programme is designed to deliver maximum traction by using minimum torque, thus avoiding waste energy from wheelspin. The vehicle is launched in four wheel-drive under electric power only via the ERAD; the diesel engine starts only when needed. This use of the electric drive allows fine control of torque, maximising traction while minimising CO2 emissions.
The Mud and Ruts Programme gives the driver two options; low torque with a four wheel-drive launch under electric power or high power and torque delivered by the diesel engine with electric assist for greater slip control and power response.
The Sand Programme is the ‘high-power’ off-road setting, appropriate for energy-sapping surfaces like loose sand. The diesel engine is boosted by the ERAD, delivering power over and above the capacity of the diesel engine alone.
