Five settings are available, each using the large, center-console mounted rotary knob. A general setting handles clean circumstances while another addresses slippery conditions created by grass, gravel or snow. Finally, three different modes are reserved for off-roading: one for mud and ruts, one for sand, and one for intense rock crawling. Once set, the system modulates ride height, engine torque response, traction control, Hill Descent Control, and all gearing. Engineers at Land Rover studied 50 different driving surfaces and concluded that most could be boiled down into the five programs they provide. This “smart” technology, according to Land Rover, is like to having an expert alongside.
