Land Rover Discovery 4 / LR4 Rock Crawl & Sand Launch Off Road

Description

The fourth generation Discovery 4 was launched in 2009, and went on sale in the United Kingdom on 1 September. Compared with the 2.7 litre TDV6 engine, which continues to be offered on the Discovery 4, the new TDV6 3.0 litre twin turbo diesel engine delivers a 9% fuel economy improvement (EU combined cycle) and 10% lower CO2 emissions, at the same time as increasing power by 28% to 241 bhp (180 kW); torque increases 36% to 600 N·m (440 lb·ft). The results include a 060 mph time of 9.0 seconds, (0100 km/h in 9.6 seconds), a 24% improvement over the 2.7 litre model. The new engine has been optimised for low-end torque as well as economy, making it possible to activate the lock-up clutch of the ZF HP-28 automatic transmission at lower speed. This reduces 'slip' in the hydraulic torque converter improving both fuel consumption and CO2 emissions. The higher torque at lower engine speeds also enables longer gearing for more economical cruising. Land Rover's engineers have also transformed the on-road ride, handling and off-road capabilities. The changes include new suspension components, revised steering, larger brakes, improved traction control, and enhancements to the Terrain Response system, which helps optimise the vehicle for different on-road or off-road driving situations. The exterior design of the Land Rover Discovery 4 has been updated, most obviously with smoother and simpler surfaces at the front, including a new, more aerodynamic bumper.
