The fourth generation of Land Rover’s flagship SUV represents a considerable evolution of the previous generation of Range Rover. It boasts significant technological improvements, more efficient engines, unique character and the first diesel-hybird variant ever. The biggest headline for the new Range Rover is the chassis, which has been made a light as possible, shedding up to 420 kg (926 lbs) for some models. Aluminum has replaced heavy steel, and the separate chassis construction has been ditched in favor of a monocoque one. This makes the vehicle more efficient and improves the on-road behavior. All the Range Rovers were equipped with full-time four-wheel-drive and had a Terrain Response Control system to detect the surface to change traction and stability. Different settings were available: General, Grass/Gravel/Snow/Mud/Ruts, Sand and Rock Crawl. The ground clearance was high due to the air suspension. As for the range of engines, the car was available with a 5.0-liter supercharged V8, a tweaked incarnation of the outgoing model's 4.4-liter TDV8 diesel, as well as a pumped-up version of the 3.0-liter V6 diesel. The interior was fitted with standard leather upholstery and an optional panoramic sunroof. As standard, the Range Rover came with dual LCD screens, one of 12.3 inch and the other one with 8-inch touchscreen that ran the infotainment system.
