Land Rover Off-Road
The Land Rover Experience Driving School
• Terrain Response System (TRS)
Land Rover’s groundbreaking off-road technology works
in concert with almost all of the vehicle’s mechanical
systems to provide drivers with optimum traction at all times.
Selected by a rotary knob on the center console, there are
five different settings to choose from:
for TRS, HDC and air suspension.
• Grass/gravel/snow and other slippery conditions
• Mud and ruts
• Rock crawl
on the setting, TRS automatically makes changes to the engine,
transmission, air suspension ride height, stability and traction
control systems, ABS, the center and rear differentials, and
Hill Descent Control.
“We analyzed the characteristics of nearly 50 different
types of off-road surface, and determined the vehicle system
inputs necessary to optimize performance on each,” said
the LR3’s chief program engineer Steve Haywood.
• Hill Descent Control (HDC)
HDC is an award-winning technology that automatically slows
the SUV’s downward progress in the four off-road TRS
settings. Using the anti-lock brakes, the car will inch its
way down a hill without the driver touching the brakes. This
can be an eerie feeling and one of things taught at the driving
school is to learn to trust that the car won’t suddenly
ease up and careen wildly down a steep boulder-strewn incline.
• Fully Independent Air Suspension
Land Rover’s computer-controlled air springs work in
concert with TRS to provide the optimal ride for on-road and
off-road conditions. In the “rock crawl” and “mud
and ruts” settings, the maximum ride height is selected,
while in “general driving” the suspension is lowered
to limit body roll and improve handling. These different heights
can also be controlled manually using a control on the center
