Terrain response
A slight turn of the round selector on the center console - and all the car systems begin to work with maximum efficiency, without any difficulty achieving the best adhesion of the wheels even with asphalt, even with a mountain trail. One only has to choose one of five pictograms describing almost all conceivable road conditions - “Grass / gravel / snow”, “Dirt / track”, “Slow movement on a rocky surface”, “Sand” or even “Disabling special programs” - The Terrain Response control unit will send orders to the entire ensemble of automotive units that strictly regulate the party of each soloist and its place in a harmonious choir.
The electronic brains of the system are scattered throughout the body of the car - from the shelter under the battery they control the engine and the transfer case, from the rear arches - the rear differential lock motor and suspension. The tentacles of the Terrain Response entered the gearbox and the ABS modulator. Its sensors are located in the engine, on wheels and pneumatic suspension elements.
By accumulating many readings, depending on the selected program, the system can slow down or accelerate the rotation of the crankshaft. An automatic transmission, applying to different types of surfaces, will shift gears a little earlier or a little later - in the mud providing the maximum effect of torque, and in the sand - on engine power. On a slippery street, the car will move from 2nd gear in an increased range, and the “Slow motion on a rocky surface” mode will load only a lower row with work.
A command arrives to prepare for the off-road - and the air suspension automatically increases clearance. Obeying the direction of the selector, Terrain Response will adjust the sensitivity of the ABC, dynamic stabilization and traction distribution systems, automatically turn on the controlled descent mode if necessary, and determine the necessary degree of differential lock.

The choice of a program that does not meet the road conditions cannot cause direct harm to the car. Although, too often trying your luck, you will noticeably reduce the life of some units. And then do not try to fool the service workers that, they say, “it itself has broken”: the control unit vigilantly monitors the use of programs, records the mileage and duration of operation of the car at the highest and lowest levels. Unless, of course, the electronics themselves fail, the degree of unreliability of the device increases in proportion to its complexity.
How much Terrain Response costs can be found out only approximately, since it is not installed regularly only on Discovery in the simplest configuration S, which costs 1, 999 thousand rubles. - by 383 thousand rubles. cheaper than the "packaged" version of SE. But at the same time as an electronic conductor, you will miss out on such “trifles” as a leather interior, an advanced music system, and a headlight washer.
