The 4th generation (L405) Range Rover again uses a
unitary monocoque body-shell, but contrary to the previous model, it is made from all-aluminium rather than steel, including unique high-strength alloy, up to 50% recycled aluminium; and production takes place in an all new aluminium facility at Land Rover's Solihull site. The all-aluminium monocoque body structure is a first for a 4x4 SUV
platform, according to Land Rover, resulting in a remarkable 39 percent lighter body-shell, and a reduction of compared to its predecessor. The Range Rover has a new version of Terrain Response, dubbed
Terrain Response2.
Powertrain The Range Rover has two diesel engines options and three petrol engines; • 3.0 L
V6 turbo diesel producing and of torque, • 4.4 L
V8 turbo diesel produces and of torque • 5.0 L V8 petrol engine unit with two versions • the naturally aspirated engine produces and of torque • the supercharged version produces and of torque. • A supercharged 3.0 L petrol V6 developing or were added in 2014. • A 2.0 L I4
Ingenium petrol Plug-in Hybrid engine available for the 2019 Land Rover Range Rover P400e. All engines use a variant of the 8 speed
ZF 8HP transmission. Gears are selected from the Drive Select rotary shifter on the centre console or the driver can also manually select gears via the paddle shift controls on the steering wheel. The car has permanent four-wheel drive with 50/50 torque split and a Magna Steyr DD295 two-speed
transfer case for high and low range options.
Suspension The Range Rover has electronic cross-linked air suspension with variable ride height. Multiple suspension modes are provided as standard, including: access, normal on-road, off-road, and two user unselectable extended heights. The car has an automated load leveling mechanism. Adaptive dynamics continuously analyse vehicle movements over 500 times per second, reacting instantaneously to road conditions and driver actions. Variable dampers adjust to maintain a composed and balanced ride. The dynamic response system (formerly known as Active Cornering Enhancement, or ACE) is able to independently adjust the front and rear hydraulic sway bars, reducing the amount of body roll during cornering, as well as enhancing control and stability at higher speeds. The system is also able to detect off-road conditions via the Terrain Response 2 system, where it dynamically reduces the level of roll compensation, to allow greater wheel articulation to increase contact with the terrain and improve comfort and control. The system is able to entirely absorb roll up to 0.4
g before gradually increasing roll. It also adjusts handling balance-reducing understeer or oversteer-by changing pressure on the front and rear stabilizer bars. This makes the car feel more agile at low speeds and more stable at high speeds.
Terrain Response The Range Rover's all-terrain capability features a new second generation Terrain Response system. The system monitors ground conditions to determine the most appropriate response to the terrain and automatically optimises vehicle settings. The system provides settings for grass, gravel, snow, mud, sand, and rock crawl, Terrain Response technology instantly reconfigures transmission, suspension, and traction settings. Controlled Acceleration Control prevents excessive speeds downhill, and Hill Start Assist prevents the vehicle from inadvertently rolling backwards.
Safety The Range Rover has driver and passenger airbags (side, seat-front, thorax and pelvis), plus airbags to protect rear-seat passengers. Other safety aids include cornering brake control, which helps to maintain stability when cornering by adjusting the driver's generated brake pressure, along with dynamic stability control to maintain control by reducing engine torque and applying braking to the appropriate wheel and correcting understeer or oversteer. ==Range Rover Long-Wheelbase, Autobiography Black (2014–2021)==
