"Outgoing Land Rover Discovery 3 is more than 100 international awards to his name, but we found a way to improve almost any vehicle design, and -.. Some subtle, some major new design marks a technical amendment to complete under the skin , and gives us the Land Rover Discovery 4, "says Phil Popham, managing director.
The star at the Land Rover Discovery 4 goes to the very effective and refined new LR-TDV6 3.0 twin turbo diesel. This gives an improvement in fuel economy 9 percent (EU combined cycle) and ten percent less CO2 emissions at the same time as the power increases by 29%, all compared to the current 2.7 liter engine. The torque is increased even more, up 36% to 600 Nm - believed to be the torque output the highest of any 6-cylinder engine production diesel passenger car in the world.
The power and torque are both available at all engine speeds, providing instant response and the ability to cruise effortlessly. The results include a 0-60 mph time of 9.0 seconds (0-100 km / h in 9.6 seconds), an improvement of 24 percent over the 2.7-liter.
Land Rover engineers have also moved the road race, and manage next-generation Land Rover Discovery 4, and also improved by almost a legendary off-road features of its predecessor. Big changes are the new suspension components, redesigned controls, larger brakes, a traction control system improved, and improvements to the award-winning terrain response, which helps optimize the vehicle for almost any road or off-road driving situations.
The interior is completely renovated and moved into a dash and center console, new seats and a host of new user-friendly features.
"The new interior are not only are much higher quality, which also won to improve its functionality. The tracks of the new console to the driver, instrumentation and controls fall easily to hand and new state LED illumination morale within the HSE models helps the interior space more pleasant and easier to use at night. We have the advantage of an indoor environment as well, with smoother surfaces, more soft materials and attention to essential details, such as pitting, "says Gerry McGovern, design director.
New features available in the Land Rover Discovery 4 also includes a portable audio interface, DAB radio, a new five-surround camera system, which makes it easier parking and towing, and a new key, which provides keyless entry and push the Start button.
"The changes and improvements to Land Rover Discovery 4 to transform many aspects of the previous generation, at the same time as increasing the flexibility and versatility, as Discovery is famous. It can carry heavy loads in its spacious interior , climb mountains, cruise through continents, tow trailers up to 3.5 tonnes, or transporting seven family and friends in comfort. I can not think of a more versatile vehicle anywhere, "says Phil Popham.
E-Land to stimulate the economy and technology to reduce CO2 emissions
The new discovery is packed with features to reduce fuel consumption and reduce CO2 emissions. The new LR-TDV6 3.0 Sequential Turbo Diesel engine was designed from scratch to provide the kind of fuel economy first, and improves low end torque.
A parallel sequential turbocharger system for a 3.0-liter diesel engine used by the biggest, most of the time the primary turbo. The smaller secondary turbo will remain in sleep mode when more power is required, reducing pumping losses and therefore fuel consumption. Very powerful, third generation common rail system with piezoelectric injectors and fuel metering, also makes a significant contribution to fuel economy.
The new engine is also optimized for low-end torque and economy, in which case you can turn the clutch lock-up is the HP-28 ZF automatic transmission at lower speeds. This reduces the "slip" is a hydraulic torque converter to improve both fuel consumption and CO2 emissions. More low-end torque also allows a longer cruise transmission loss.
Discovery incorporates several energy saving features. At the stop, the idle speed of the V6 engine was reduced from 750rpm to 710rpm, which provides fuel savings without compromising refinement. Intelligent Power Management system includes intelligent regenerative charge as much as possible the alternator recharges the battery when it is cheaper to do that when the car is coasting rather than accelerating.
Aerodynamic changes to the front, lower front spoiler with revised and new front wheel deflectors, helping to reduce drag by increasing air under the floor.
The new air conditioning pump driven by a clutch that disengages when the air conditioner is not used to reduce parasitic losses and improvements in fuel consumption and CO2 emissions.
At the heart of improvements in the Land Rover Discovery 4 new diesel is a unique and very effective. The 3.0 TDV6 turbodiesel LR-sequence is based on the current LR-displacement 2.7-liter TDV6, but radically redesigned to provide significantly better performance, lower emissions and greater fuel economy.
2.7-liter has won many admirers as a refined diesel engine ever made. The new twin turbo, LR-TDV6 3.0 offers a significant increase in both electricity - up to 29 percent of 245PS - and torque, up 36 percent of 600 Nm The ability to provide a maximum torque of just 2000 rpm, combined with an atmosphere unparalleled significantly improve the ability of Discovery has already been praised on both road and off road.
But despite this increased power, engine emissions are drastically reduced. When equipped with the DPF, the new LR 3.0 TDV6 meets emission Euro 5 (not to come into force until 2011) and the figure of 244g/km CO2, it undermines the current 2.7-liter automatic ten percent. Fuel economy is improved by 9 percent, produces 30.4mpg (9.3 l/100km), the EU combined cycle.
The new 3.0-liter engine has been developed a common Jaguar Land Rover team that has a pedestal was designed from the beginning of the two characters in mind. High torque and quick response at low revs and is well suited to the Jaguar and Land Rover DNA. Version of the Jaguar AJ-V6D Gen III, D, was recently launched in the new Jaguar XF.
LR-TDV6 engine has a cover over his brother Jaguar, to ensure the effectiveness of the lubrication system is not compromised when venturing off road. The system to trap oil from the turbocharger has been improved to a similar reason, ensuring that no oil accumulates in the turbochargers at extreme angles in the off-road conditions.
Land Rover waterproof version for belt, which is the generator, air compressor, power steering pump and starter. The engine is specifically set to allow a greater demand for Land Rover Discovery 4, especially for towing and driving off-road.
Twin Turbos - very efficient, very responsive
A key feature of the new LR-TDV6 3.0 is a unique parallel sequential turbocharger system, the first of its kind installed in the V-engine in the world. Generates high torque throughout the speed range of the engine, improved throttle response and low CO2 emissions, twin turbochargers work in line to offer a response like no other and best-in-class low-end torque, but also pack a huge punch at higher speeds.
Driving a turbocharger requires a pressure of the exhaust, creating pumping losses in the engine and increases fuel consumption. Under the control of engine management system, valves to isolate the secondary from both the exhaust stream of the turbocharger and the intake tract of the engine when not needed. A pipe connecting two collectors balance allows gas to supply two turbo collectors around the principal.
The new 3.0-liter diesel can significantly outperform its competitors by offering 500 Nm at just 500 milliseconds between idle, unlike many diesel engines, such as turbo lag at very low speeds. From the perspective of the driver, this means instant access to 84 percent of maximum torque.
The new common-rail fuel injection system delivers up to five injections per cycle, 2000bar pressure. Each nozzle tip is perforated in seven holes, through which finely atomized fuel is injected into the cylinder. High-pressure injection for more power, better fuel economy and reduce emissions of CO2 and particulate matter. New, high-speed piezo injectors are designed to maintain the injection to reduce noise to a minimum.
"Packs" of piezo injectors operate each extension when an electric current is passed through them. They respond almost immediately, but make a strong click when cooking, which can add to the noise of the diesel engine at idle. The crystals in the new injectors are fitted with Land Rover closer to the edge means they are mounted on the interior of the engine give better sound insulation and quieter operation.
A new third-generation fuel injection is the "Mode". Traditional common-rail diesel pumps, injectors oversupplied with the surplus is returned to the fuel tank. During this process, the temperature of the fuel and coolant rises to spend a considerable amount of energy. In measurement mode, the pump provides the fuel injectors are only needed for speed. As a result, there is no increase in temperature of the fuel and no waste of energy.
Rugged and lightweight
The two cylinder heads with four valves per cylinder, is made of an aluminum engine block is made of compact graphite iron (CGI), as before. The tensile strength greater than the CGI can take a small block some 80mm shorter than a conventional "gray" equivalent in cast iron.
The new, water-cooled exhaust gas recirculation (EGR), which is important to reduce pumping losses and NOx emissions from diesel engines are more efficient and consumes less power than its predecessor, with the valve allows the system to unloading is in the "hot side" closer to the engine exhaust manifolds. These valves are not cool when the engine is running, so there is no condensation of combustion deposits which takes place the engines were equipped with a "cold side" valves, so that the EGR system always operates at full power . Since the EGR cooling is so effective, the exhaust gases can bypass the system and return to the exhaust pipes that allow faster engine warm-up period, and begin to reduce emissions further.
EU 5 emissions are achieved through conventional catalysts and diesel oxidation diesel particulate filters (DPF). NOX levels are sufficiently reduced at source by designing the combustion system, the addition of the new common rail injection system and EGR with new bypass. As a result, specialized NOX after-treatment is unnecessary, thus avoiding the potential costs and the need to use other precious metals in the exhaust system.
Greater sophistication
CGI cylinder block and new piezo injector design reduces combustion noise in the new engine. Multiple injections of fuel in the precise race also reduce combustion noise and combustion engine including all the covers camshaft covers, the front pages and the marsh has been optimized to suppress noise.
A new analysis of diesel has been using the latest techniques of computer-aided design, followed by a complete test. All the chambers of the motor coasts to minimize radiated noise.
Internal friction, a major unnecessary fuel consumption, was approached by careful optimization of the crankshaft, valves and pistons. All these features combine to make the new LR-TDV6 3.0 diesel turbo sequential one of the quietest diesel premium in the market today, with service intervals of 16.000 miles has increased.
Levels of sophistication of the new LR-TDV6 engine is such that Land Rover's patented device for the filler neck of diesel fuel, to reduce the risk of fueling with gasoline, inadvertently, is mounted on the new Land Rover Discovery fourth
New transmission response
The LR-3.0 TDV6 is coupled to the review and super smooth ZF HP28 6-speed automatic transmission. Its characteristics have been optimized by Land Rover engineers to provide a first class response, with rapid changes and refined. The dramatic improvement in power and torque at low engine speed range of the new engine allowed to operate in lock-up clutch transmission much earlier in each speed, reducing drag through the hydraulic torque converter to help improve fuel consumption and CO2 emissions.
Dynamic major advances introduced by the Land Rover Discovery 4 Architecture include revised suspension, improved steering, bigger brakes and improved versions of the award winning Response field of Land Rover and Hill Descent Control system.
It also increases the bushes and the new new front and rear ride quality shock absorbers.
The variable rate rack and pinion assembly revise, supplement improved ride quality by reducing the "twitchiness' around the axis at high cruising speed and sensitivity increased slightly to higher lock angles. This increases the feeling of participation of the pilot high-speed maneuvers, and also increases the precision control at low speed and off-road.
The modified front bumper to help the steering feel, for its new anti-roll lips to reduce aerodynamic lift front of vehicle up to 50% at higher speeds.
Stop the increased power
The biggest new braking system was introduced with the new engine to serve the Land Rover Discovery 4 best performance and improve braking feel.
This new system is derived from the four-piston opposed caliper system performance used in the Land Rover Range Rover Sport. It uses a 360 mm disc, ventilated front with a new cast iron twin-piston caliper slide - which serves to reduce the size of the front brake package while maintaining its rigidity, which helps deliver an excellent pedal feel .
The rear uses a single sliding piston vented disc caliper 350 mm, which is now made of aluminum to help reduce vehicle weight.
Also, before the brake system is a new feature emergency brake light. When the vehicle commits a serious or emergency braking, brake lights flash to reduce the risk of collisions.
Add to the control curves
A refinement of the system management control can automatically brake the car when taking a turn too fast, increase the driver's control.
The system operates on the control inputs of the driver. In extreme cases, the automatic braking will reduce vehicle speed, the level of brake pressure is used in accordance with the steering inputs. The automatic braking to the "emergency" can be used when the application for entry.
Updates to gain ground ResponseTM and Hill Descent Control
4 for the Discovery, Land Rover's terrain response system, award-winning gets new features and enhancements to further expand its off-road vehicle tires feature. Terrain Response system to optimize the vehicle set-up for almost all of the road or off-road driving conditions, five different settings to suit different terrains:
General Conduct
Grass / gravel / snow
Sand
Mud and ruts
Rock crawling
If the soft sand - one of the power-hungry surfaces - "Launch Control Sand 'was introduced, which allows much easier to escape. The new, depending on the speed of the wheel-slip traction control system objectives allow only a very limited slip Initial wheel, to help prevent the wheels to dig up the sand.
Land Rover's acclaimed Hill Descent Control is to improve the Land Rover Discovery 4, except that the Gradient Release Control. This prevents the initial acceleration when descending steep hills, increase control and eliminate potentially alarming deficiencies that arise when the brake is released at extreme angles.
The system operates automatically, Hill Descent is enabled, temporarily maintains brake pressure after the driver released the brake pedal. Then gradually help the brake pressure to control the vehicle speed and acceleration. When the off-road vehicle speed is achieved, Hill Descent Control will take the vehicle to the bottom of the track is the usual way.
A new face on a distinctive design
The Land Rover Discovery has changed the design of a heritage of more than 20 years and four generations of iconic vehicle, instantly recognizable. Land Rover Discovery 4 inherits the clean lines of the previous generation, but now subtly updated and given a higher level, a more contemporary look.
Smooth, simple surfaces used in the front, giving the vehicle a new character, highlighted by the lights in front of the sporting future, with new LED lights set in a profile of the firm, increasing individual units around light principal. It also introduces a new light on the rear of the vehicle, which incorporates technology LED brake, tail and indicators.
The new front bumper has larger cooling hole to match the new engine more power. Cleverly, a larger buffer to truly improve aerodynamics of a vehicle, reducing drag, thanks to its innovative anti-drag "lips", which facilitate the flow of air around the front wheels in the front bumper.
Again, two seven-spoke 19 "wheel design introduced on the Land Rover Discovery 4 to complete the current 7-spoke 19" wheels and, for the first time, hitting a new 10-spoke 20 "wheels are available as a factory fit option.
Three new full color external changes to Land Rover Discovery 4 - Nara bronze, blue and sand Bali Ipanema.
"Inside the Land Rover Discovery 4 continues to offer drivers and passengers excellent visibility and versatility. But the redesigned dashboard and console architecture and use of premium materials, make the car a much more attractive place to be. " Gerry McGovern
The new interior Land Rover Discovery 4 combines smooth surfaces and flows significantly reduces the complexity and volume control. It provides a much softer, flexible premium interior, but still with a signature architectural theme of the Discovery.
The new console is angled towards the driver to control, visibility and access. It seems more to point out that as the Range Rover Sport, Discovery 3 Output Control Terrain Response is now more prominently located opposite the center console, opening the way for a cup easier to drive along the center console.
All models feature a new steering wheel, revised to change the layout data of the driver, remote audio controls, cruise control and heated steering wheel.
Natural selection-Target Woods, as well as sewn and wrapped instrument panel, center console and doors, add a custom-crafted feel. There are also two new interior colors, however, half shade darker than the Arabica and nutmeg, to supplement the existing Almond Colourway bright interior.
The new headquarters is introduced for lines one and two, with a new profile seat cushion before expanding to better support and comfort of the seats and for the first time, the front seats have height-adjustable headrests in place of handles traditional seat-mounted. HSE vehicles specified with the Premium package with leather seat also electrically adjustable lateral reinforcement, which allows occupants to adjust their chairs in front for support.
For convenience, electric seats with memory control is shifted to the cabinet door.
New interior lighting mood is the finishing touch on the inside, with the introduction of white LEDs to cast halos around subtle silver interior door handles and pockets. The console and center fascia with soft seam, and the apparatus is shown in the "noble" of finalists also benefit from the ambient lighting inside the vehicle when the lights are on.
Simple technology
Land Rover Discovery 4 is equipped with easy-to-use and useful, not technology for the sake of technology. The goal is to simplify the whole operation, to help make your vacation more relaxing and stress-free
In and out, for Land Rover Discovery 4 receives a large number of relevant new technologies that improves the driving experience.
The navigation system accepts user-friendly navigation structure, which is now also "Towards a guide." This will complement the map intersection and icon-based information package for the actual road signs along the way look at the driver.
The new portable audio interface allows connection to a series of personal audio storage devices, USB drives and MP3 players, so the functions of the various devices "to be accessed and controlled via facia mounted touch screen system. One of the ports of connectivity, is a dedicated Apple PodTM single point by Land Rover for the continued functionality of extreme driving conditions, helping to prevent the device to detach from the socket.
A new 5-inch Thin Film Transistor (TFT) display driver information is also put in place by the fourth Land Rover Discovery Sitting in the redesigned instrument panel, displaying the message center provides key sent in a clean, simple and user friendly.
And a cleaner, crisper audio radio is now available thanks to the introduction of Digital Audio Broadcasting (DAB) in most European and Asian markets, and HD Radio in the United States. With the beautiful listening experience, with additional features such as news headlines, song title and artist.
Cutting edge user-friendly technology
The exterior of the vehicle, convenience and improved relevant new systems, safety and security.
The headlamps incorporate new technologies, high-assist beam. It can automatically switch beam when external light levels are below the threshold of the system. Above all, the system is designed to detect approaching vehicles and precedent, and in a split second will automatically return to the crossing to avoid dazzling other.
The key input new remote sends the signal required for entry into the passive vehicle by the holder of the key, simply by touching the door handle without using the button the'unlock on the key ring. The new key also generates the necessary signal push button to start the vehicle. Sophisticated sensors recognize the presence of the key in the car, confirm security information, and accept the 'start' command via the new fascia mounted start / stop button.
No less than five digital cameras are the new camera system at all, reinstalling the touchscreen one about 360 degrees. The cameras operate the vehicle is started immediately, and can be used at speeds up to 11 mph, with options to select and zoom to help nearby parking and towing.
. "Hinata help function (selected via the touch screen menu) to perform precise movements of the towing side view of the wide range of cameras provide a clear picture of the trailer is reversed: the images are electronically manipulated to provide distorted vision, guidelines on the top a rearview camera and the image shows the trajectory of the vehicle and trailer.
Specific characteristics such as type of trailer axles and width guides can be entered into the system to improve the system outputs.
Another support for towing, trailer stability assist, detects the oscillations of the trailer followed by a significant tool such behavior steering movements without being invited and the swing of light vehicles in response to the behavior trailer. In these circumstances, the system can initiate engine torque reduction and brake intervention to bring the tractor under control.
