the land rover terrain response system
land rover's patented terrain response(r) system was first introduced on the discovery 3 and today it is fitted to all models as standard equipment. terrain response(r) enables the driver to adjust chassis and transmission settings to suit the terrain being traversed. five settings are available through the twist of a rotary knob located on the centre console.
There are Terrain Response (r) settings for all driving conditions including general driving; grass, gravel, snow; mud and ruts; sand; and rock crawl. Suspension ride height, engine management, throttle mapping, transfer case ranges, transmission settings, electronic driving aids such as Electronic Traction Control (ETC), Dynamic Stability Control (DSC) and Hill Decent Control (HDC) and electronic 'e-diffs' are all operated by way of the Terrain Response(r) system.
All Range Rover Sports models are equipped with a standard centre Magna Steyr Powertrain electronic differential otherwise known as an 'e-diff,' which electronically locks and unlocks and apportions torque through the means of a multi-plate clutch pack situated within the transfer case which also provides 'shift-on-the-move dual range operation.
A rear e-diff which is able to lock and unlock instantaneously can be fitted as an option on Range Rover Sport models.
Land Rover offers an in-dash display linked to Terrain Response(r). This presents essential off-road driving information such as the angle of the steering, wheel articulation and the status of the e-diffs. Rather importantly, the display also informs drivers which wheels are not in contact with the ground.
Today's Range Rover, Range Rover Sport and Discovery 4 all feature Land Rover's unique and effective Terrain Response(r) system that assist drivers during different driving conditions: rock crawl, mud and ruts, sand, grass/gravel/snow or road, Terrain Response(r) can help drivers to traverse all these conditions. It's a groundbreaking feature that should and can be used in conjunction with proactive driving techniques.
Land Rover has issued some information for those who wish to put its Terrain Response(r) system to the test.
? Use steady momentum to carry you through deep sand or mud.
? Do not select a gear that is too low in mud because it will spin tyres more easily.
? However, in sand a low gear is usually better.
? If muddy conditions force you to drive in ruts, make sure you know where your front wheels are pointing at all times.
? Tyres can cut through mud to find traction on firmer ground below.
? Sand is firmest at dawn.
? If you have to sit out a sandstorm, turn the rear of the vehicle to face the wind, and then turn the engine off.
? Follow the tyre and Land Rover's advice on tyre pressure. However, where the sand is soft and contains stones, a low pressure works better. When the wheels start to spin, ease off the throttle and allow the tyres to slow down and regain traction.
Remember too, before setting out on your adventure, always make sure you and your passengers are wearing climate-suitable clothing.
