This system has now evolved and for 2013 model year the radio has been upgraded to the latest generation DAB+ and DMB-A broadcast formats and a new digital TV tuner has been introduced across all derivatives, capable of receiving MPEG4 digital streams.
In line with the improvements introduced in 2012, the entry level audio is an 8-speaker system with colour display and options for Bluetooth, and USB/iPod connectivity; the High-line Harman Kardon System has 11-speakers and an output of 380W, whilst the Premium Harman Kardon LOGIC 7 system has 17 speakers and delivers an amazing 825W.
Touch screen is available independently of the navigation system and Rear Seat Entertainment (RSE) is equipped with a single slot DVD drive in the audio head unit so the disc can be conveniently loaded from inside the cabin.
The rear seat audio system incorporates WhiteFireTM cordless headphones, and can also be controlled by wireless remote control. The system supports connectivity with games consoles and video playback of MP4 files stored on USB. The phonebook stores several thousand entries, whilst the TFT Message Centre interface displays audio, phone and navigational information.
Land Rover Homelink
The Homelink option is available with High Beam Assist and can learn the frequencies of most transmitters used to operate automated garage doors and gates. The press of a button is all it takes to operate.
Efficient, powerful and refined 3.0-litre diesels
The tremendously responsive 3.0-litre sequential turbo diesel engines come in two versions, 256PS and 211PS (the latter being available on commercial derivatives only), producing 230g/km and 224g/km CO2 respectively.
These diesel engines are equipped with the same parallel sequential turbocharging system and third generation common rail fuel injection system. Throttle response is staggering with maximum torque available from only 2,000rpm. The 3.0-litre diesel can significantly outperform its rivals by delivering 500Nm in only 500 milliseconds from idle. When it was introduced at 2010 model year, the parallel sequential turbocharging system was the first of its kind to be fitted to a V-engine anywhere in the world. The twin turbochargers work sequentially to provide best in class torque at low speeds and pack a huge punch at high speeds.
A variable geometry, medium-sized turbocharger is in use most of the time during average acceleration and up to motorway cruising speeds and performs with no discernible lag. This is more efficient than series turbocharging systems where the smaller primary turbo increases energy losses.
The third generation common rail fuel injection system operates at 2,000bar, the piezo injectors minimising noise while optimising combustion. The system operates in ‘metering mode' supplying just the right amount of fuel to the injectors rather than returning it to the tank and wasting energy in the process. All diesel models are now fitted with a DPF and have an advanced EGR system to reduce NOx.
ZF 8HP70 automatic gearbox
The remarkable ZF 8HP70 transmission delivers unrivalled response for driving pleasure while driving fuel consumption and CO2 emissions down to an all-time low. Eight speeds provide closer ratios and a greater overall ratio spread, while the higher overdrive ratio compliments the huge torque of the 3.0 LR-SDV6, reducing fuel consumption and CO2 emissions. Efficiency is further improved by the internal mechanical layout of the 8HP70 which means that no more than two internal clutches are open at any one time.
The 8HP70 is packed with energy saving features. The hydraulic actuating system is more efficient too, the hydraulic pump drawing less energy from the engine. The torque converter is calibrated to lock-up at lower speeds and operating temperature, reducing fuel consumption and once again taking advantage of the 3.0-litre diesel engine's immense low-end torque. Transmission Idle Control seamlessly and transparently selects neutral when the car is stationary and the engine idling in drive, reducing drag on the engine and saving fuel. In hot conditions it selects a lower gear to run the engine and air conditioning pump faster to cool down the cabin quickly. In cold conditions it runs the engine faster to reduce warm-up time and emissions.
The 8HP70 offers performance benefits too. Taking just 200 milliseconds to complete the entire shift event, the 8HP70 gears change with an imperceptible interruption of torque for smoothness equalling that of a dual-clutch transmission, while providing a more sophisticated driving experience. The 8HP70 matches the engine speed to its turbine speed in anticipation of oncoming downshifts for an absolutely smooth transition from one ratio to the next. Closer ratios also contribute to making individual shifts smoother.
Driver Type Detection monitors driver inputs and the car's systems to optimise the response of the gearbox to the driver's style, while Curve Detection makes sure the gearbox avoids unwanted upshifts and holds on to the same gear when taking a sequence of bends. The gearbox also monitors the driver's use of the brake together with the rate of deceleration to set up the correct gear for entry and exit to the corner. The 8HP70 does not have to change to a lower gear sequentially and can skip up to six ratios if necessary, for much faster response when preparing to overtake.
Driver controls include steering wheel paddles as standard enabling the driver to take control of gear shifting manually. The rotary switch selects park, reverse, neutral, drive or sport modes, the last of these optimising the gearbox response times for maximum acceleration, improved response and sharper upshifts.
On- and off-road breadth of capability
The Discovery 4 suspension system is widely acknowledged as being the most versatile ever developed for both on-road and off-road use. A variable ratio steering rack gives greater stability during high speed cruising and increased sensitivity at acute steering angles. Powerful brakes comprise twin-piston sliding callipers with 360mm ventilated discs at the front and single piston with 350mm ventilated discs at the rear. The understeer control system intervenes by automatically slowing the vehicle to bring it back under driver control.
Land Rover's acclaimed Terrain Response® system includes a setting for general driving; grass, gravel, snow; mud and ruts; sand; and rock crawl. Two additional features were added in 2011: Hill Start Assist which automatically retains the driver-generated brake pressure when the driver's foot moves from brake to throttle without the car rolling backwards; and Gradient Acceleration Control, designed to provide safety cover on severe gradients when the driver does not have Hill Descent Control engaged. By pressurising the brake system, Gradient Acceleration Control slows the car to a limit determined by the throttle position when the car is descending the slope in the driver's intended direction of travel.
e_TERRAIN TECHNOLOGIES boost economy and lower CO2 emissions
The Discovery 4 is packed with features aimed at reducing fuel consumption and reducing CO2 emissions.
The parallel sequential turbocharging system of the 3.0-litre diesel makes use of its larger, primary turbo most of the time. The smaller secondary turbo remains dormant when higher power is not required, reducing pumping losses and consequently, fuel consumption. The highly efficient, third generation common rail injection system with piezo injectors and fuel metering, also makes a substantial contribution to fuel economy.
Engines have also been optimised for low-end torque as well as economy, making it possible to activate the lock-up clutch of the ZF 8HP70 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 rpm also enables longer gearing for more economical cruising.
The Discovery 4 incorporates several other energy saving features too. At standstill, the idle speed of the V6 is a low 710rpm, using the minimum of fuel without compromising refinement. An Intelligent Power Management System includes Smart Regenerative Charging, so whenever possible the alternator charges the battery when it is most economical to do so, such as when the car is coasting rather than accelerating.
Aerodynamic features at the front end such as the lower chin spoiler and front wheel deflectors help to reduce drag by increasing underfloor airflow. The air conditioning pump is driven through a clutch which disengages when the air conditioning is not in use, reducing parasitic losses and delivering improvements in fuel consumption and CO2 emissions.
