Range Rover Fourth-generation L405

The Range Rover L405, is the fourth-generation of Range Rover to be manufactured by Land Rover. It was first shown the 2012 Paris Motor Show. It differs from previous generations by using an all-aluminium monocoque body.

Specifications

The platform is an all-aluminium monocoque structure which is a first for a SUV, resulting in a reduction of 420 kg (925.9 lb) compared to the outgoing model. The Range Rover has a new version of Terrain Response, dubbed Terrain Response 2.

Powertrain

The Range Rover (L405) is powered by two diesel engines and one petrol engine; 3.0 L V6 turbo diesel producing 260 PS (191 kW; 256 hp) of power and 600 N·m (443 lb·ft) of torque, 4.4 L V8 turbo diesel produces 344 PS (253 kW; 339 hp) of power and 700 N·m (516 lb·ft) of torque, a single 5.0 L V8 petrol engine unit has two versions, naturally aspirated engine produces 380 PS (279 kW; 375 hp) of power and 510 N·m (376 lb·ft) of torque while supercharged version produces 510 PS (375 kW; 503 hp) of power and 625 N·m (461 lb·ft) of torque.

All engines are mated to eight-speed automatic transmission. Gears can be selected from Drive Select Rotary Shifter from the centre console or driver can also manually select gears via the paddle shift controls on the steering wheel.

The car has permanent intelligent four wheel drive with 50/50 torque split and a two-speed transfer box for high and low range options, helping to maintain traction and stability in challenging conditions on-road, off-road, or when towing.

 Suspension

The Range Rover (L405) has electronic cross-linked air suspension (with variable ride height), with multiple suspension adjustment modes are provided as standard, including access, normal on-road, off-road and extended height. A new extra intermediate setting adds greater convenience and improves handling across the vehicle’s breadth of capabilities. The car has automated Load leveling mechanism.

Advanced, intelligent suspension technologies assist the Range Rover’s performance and achieve consistent driving refinement, on and off-road. Adaptive dynamics continuously analyse vehicle movements over 500 times per second, reacting instantaneously to road conditions and driver actions. Infinitely variable dampers adjust to maintain a composed and balanced ride.

Dynamic response system transforms handling and the comfort for all occupants. It independently adjusts and monitors front and rear suspension units, reducing the amount of body roll during cornering, as well as enhancing control and stability at higher 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 for an enhanced and assured experience for almost all driving conditions. The system provides settings for grass, gravel, snow, mud, sand, and rock crawl, Terrain Response technology instantly reconfigures transmission, suspension, and traction settings for maximum drivability in almost all conditions. Controlled Acceleration Control prevents excessive speeds downhill, and Hill Start Assist prevents the vehicle from inadvertently rolling backwards.

Safety

The Range Rover (L405) 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 under-steer or over-steer.
