The class-leading breadth of capability is extended even further wîth improvements for both on-road and off-road driving.
'The outgoing LR3 has well over 100 international awards to its name. Yet, for the new LR4, we've found ways to improve virtually every aspect of the vehicle's design and engineering; some subtle, some major. New design signals comprehensive engineering change under the skin.'
-Phil Popham, Land Rover Managing Director
Star billing on the LR4 goes to the highly efficient and refined new LR-V8 direct injection engine. This delivers 25% more power and 19% more torque than the previous 4.4-liter engine. Power and torque are both immediately accessible across the entire rev range, delivering quick throttle response and effortless cruising ability, wîth 60 mph arriving from rest in just 7.5 seconds (0-100km/h in 7.9 seconds.)
Land Rover's engineers have also transformed the LR4's on-road ride and handling while also improving the acclaimed all-terrain capabilities of its predecessor. Comprehensive changes include new suspension components, revised §teering, larger brakes, improved traction control, and enhancements to the award winning Terrain ResponseTM system which helps optimize the vehicle for virtually all on-road or off-road driving situations.
The iconic exterior design has been updated, most obviously wîth smoother and simpler surfaces at the front, including a new, more aerodynamic bumper. The sportier new lights help give the vehicle new character, and include LED technology front and rear. The sleek new front headlights include available High Beam Assist, automatically switching on or off the high beam, as conditions require.
Aerodynamic changes to the front end include revised front lower chin spoiler and new front wheel deflectors, helping to reduce drag by increasing underfloor airflow. The LR4 is fitted wîth new 19-inch wheels and tires giving high rolling resistance and improved tire wear.
The interior is completely redesigned, wîth a transformed dash and center console, new seats and an array of new, user-friendly features.
'The new interior not only has a much more premium look and feel, it's also gained improvement to its functionality. The new console inclines towards the driver, the switchgear and controls fall more readily to hand, and new LED ambient lighting helps make the cabin a more pleasant and more easily used space after dark. We've made the interior environment finer too, wîth smoother surfaces, softer materials and close attention to critical details such as stitching.'
-Gerry McGovern, Land Rover Design Director
New features available for the LR4 include a portable audio interface, available HD Radio, a new available Surround Camera System, for easier parking and towing, and a new key system which offers Keyless Entry and Push Button start.
'The changes and upgrades for LR4 transform many aspects of the previous generation, at the same time enhancing the flexibility and versatility for which this vehicle is famous. It can carry huge loads in its spacious interior, climb mountains, cruise across continents, haul trailers* or transport up to seven family and friends in comfort. I can't think of a more versatile vehicle anywhere.'
-Phil Popham, Land Rover Managing Director

All new, LR-V8 5.0-liter direct injection engine
Designed entirely in-house by Jaguar Land Rover powertrain engineers, the 5.0-liter
LR-V8 is one of the most advanced engines ever built. The new LR-V8 develops 375 hp and 375 lb.-ft. torque, bettering the previous 4.4-liter V8 for power and torque by 25 percent and 19 percent, respectively. Yet, when it comes to emissions, the engine meets the stringent American ÚLEV2 (ultra low emissions vehicle) regulations.
'Our new 5.0-liter V8 was conceived from the onset wîth Land Rover models in mind. Designed wîth the emphasis on low-end torque, it is particularly suited to the LR4's wide range of capabilities both on and off road.'
-Malcolm Sandford, Engine Group Chief Engineer
The LR4's new 5.0-liter LR-V8 is optimized for a balanced combination of performance and efficiency, thanks to its wealth of new features and firsts.
Direct injection – increased power and torque wîth optimized emissions
A key feature of the new LR-V8 is an -first, centrally-mounted, multi-hole, spray-guided fuel injection system, delivering fuel at a pressure of up to 150 bar (2,175 psi) directly into the cylinder. Twin, high pressure fuel pumps are driven by an auxiliary shaft in the all new engine block. Direct injection has contributed substantially to improved low-speed response, particularly useful when off-road while adding to driving pleasure on-road. The charge-cooling effect of direct injection has allowed the compression ratio to be raised to 11.5:1.
New Variable Camshaft Timing boosts engine torque, saves energy
A new type of Variable Camshaft Timing system (VCT) introduces another first. The four VCT units are activated by the positive and negative torques generated by opening and closing the intake and exhaust valves, instead of by oil pressure. As a result, the oil pump has been reduced in size, saving energy and improving efficiency.
The VCT units work independently on all four camshafts and timing is optimized by the engine control unit for torque, power and economy at every point in the engine's speed range. The response rate of the new VCT units is 25 percent quicker than the previous system, and therefore delivers a more immediate engine response to the driver's demand.
The new engine has also been optimized for low-end torque, making it possible to activate the lock-up torque converter of the ZF HP28 automatic transmission at lower speed, helping reduce CO2 emissions. Improved torque at lower rpm also enables taller gearing for more economical and relaxed cruising.
The LR4 incorporates several other energy-saving features. At a standstill, the idle speed of the V8 has been reduced from 700 to 600 rpm, yielding fuel savings without compromising refinement. An Intelligent Power Management System includes smart regenerative charging. When possible, the alternator charges the battery when it is most economical to do so, such as when the car is coasting rather than accelerating.
Strong and compact
The new LR-V8 engines are built around a stiff, all new, aluminium block wîth cast-in iron liners and cross-bolted main bearing caps, to reduce noise, vibration and harshness. For the first time at Land Rover, the blocks are high pressure die-cast rather than sand-cast, providing a superior finish and dimensional greater accuracy. The engines also have aluminium heads, wîth four-valves per cylinder and strong, spheroidal-graphite cast-iron crankshafts and steel connecting rods. The cylinder heads and blocks are manufactured using recycled aluminum alloy for the first time, thus reducing the environmental impact of manufacturing the new engines. It is also a more compact power unit than its predecessor, partly due to the relocation of the oil pump.
5.0-liter LR-V8 engine highlights
• 375 hp and 375 lb.-ft. torque
• 25 percent more power, 19 percent more torque than the previous 4.4-liter engine
• Meets ÚLEV2 emissions regulations
• Multi-hole, central spray-guided direct injection – first.
• Torque-actuated variable cam timing on all four cams – first on a V8
• Cam profile switching, variable-length inlet manifold optimizes power and torque
• Reverse-flow cooling system improves engine and cabin warm-up
• Low-friction design
• Lightweight construction uses recycled materials
• 15,000 mile (24,000 km) service intervals
The new LR-V8 engine has been developed by a joint Jaguar Land Rover engineering team, wîth base characteristics designed from the onset wîth the requirements of both brands in mind. High levels of torque and fast response from low revs perfectly suit both Jaguar and Land Rover driving needs. The Jaguar version, the AJ-V8 Gen III, was recently launched in the new XF sports sedan. (concept carz)
Although the basic architecture of both engines is the same, the Land Rover version has a number of special developments. The LR-V8 has a deeper, pressure die-cast sump to accommodate the extreme tilting angles that Land Rover vehicles can be subjected to during all-terrain driving. The LR4's LR-V8 is also fitted wîth a mechanical cooling fan and, for packaging reasons, the intake manifolds have been designed especially for the vehicle, while achieving lower levels of noise vibration and harshness (NVH).
For the Land Rover version, belt drives are waterproofed, as are the alternator, air conditioning compressor, power §teering pump and starter motor. The engine is also tuned specifically for towing and all-terrain driving demands.
Responsive new transmission
The 5.0-liter LR-V8 engine is mated to the revised and super-smooth ZF HP28 6-speed automatic transmission. (posted on conceptcarz.com) Its characteristics have been optimized by Land Rover engineers to provide class-leading response, wîth rapid and refined shifts. The dramatic enhancement of both power and torque low down the rev range on the new engines have made it possible to actuate the transmission's lock-up clutch much earlier in each gear, reducing slip through the hydraulic torque converter and therefore helping both fuel consumption and CO2 emissions. The transmission also features an intelligent sport mode, which can sense and adapt transmission characteristics to particular driving styles.

Major dynamic advances in the LR4 include revised suspension architecture, improved §teering, larger brakes and enhanced versions of Land Rover's award-winning Terrain ResponseTM and Hill Descent Control systems.
The list of changes starts wîth new suspension knuckles, designed to reduce the separation between the suspension roll center and the vehicle's center of gravity, a reduction of 1.65 inches (42mm) in front and 2.44 inches (62mm) in the rear. This dramatically reduces the vehicle's natural body movements when cornering. Roll rates are further controlled by a stiffer, larger rear anti-roll bar.
New bushings and new front and rear dampers enhance ride quality. The variable ratio §teering rack is revised, complementing the improved ride quality by improving center line stability during high-speed cruising and slightly increasing sensitivity at greater angles of §teering lock. This enhances feel in high-speed maneuvers and also increases precision for low-speed control and off-roading.
The redesigned front bumper also helps improve §teering feel, as its new front wheel deflectors help reduce aerodynamic lift in front by 50% at higher speeds.Increased stopping power
A new, larger brake system has been introduced to cater to the LR4's enhanced performance and to improve braking feel. This new system is inspired by the four-piston, opposed-caliper high-performance system from the Range Rover Sport. It employs 14.2-inch (360mm) ventilated front discs wîth new, cast iron twin-piston sliding calipers, reducing front brake package size while preserving stiffness and excellent pedal feel. At the rear, single-piston aluminum sliding calipers now help reduce weight and clamp down on 13.8-inch (350mm) ventilated discs.
More control in the corners
A refinement to the Dynamic Stability Control system helps automatically slow the vehicle if taking a corner too fast, enhancing driver control. The system operates according to §teering inputs from the driver. In extreme cases, automatic braking intervenes to reduce the vehicle speed, wîth the braking pressure level applied according to the §teering inputs.
Úpdates for award-winning Terrain ResponseTM and Hill Descent Control
Land Rover's award-winning Terrain ResponseTM system gains new features and refinements, further extending the vehicle's all-terrain capability. Terrain ResponseTM optimizes the vehicle set-up for virtually all on-road or off-road driving situations, wîth five different settings to suit different terrains:
• General driving
• Mud and ruts
• Rock crawl
For soft sand – one of the most power-hungry surfaces – Sand Launch Control has now been introduced, which makes for noticeably easier drive-away. New, speed-dependent targets for the traction control system permit only very limited wheel slip, helping to prevent the wheels digging down into the sand.
Revisions to the Rock Crawl program apply low-level brake pressure when the vehicle is in First or Reverse gear at speeds below 3 mph (5km/h). This low-level brake force reduces the vehicle's roll tendency and the intervention of the traction control system, giving a more composed drive through rocky terrain.
Land Rover's much-acclaimed Hill Descent Control system is enhanced on LR4 wîth the addition of Gradient Release Control. This inhibits the initial rate of acceleration when descending very steep inclines to increase control when braking is released at extreme angles. The system activates automatically whenever Hill Descent Control is engaged, temporarily maintaining brake pressure after the driver releases the brake pedal. It then progressively eases braking pressure to control vehicle momentum and acceleration. Once the vehicle's target off-road speed is achieved, Hill Descent Control operates to take the vehicle to the bottom of the slope in its customary composed manner.
A new face on a distinctive design
The Land Rover LR4 has evolved a distinct design heritage over 20 years and four generations of iconic, instantly recognizable vehicles. LR4 inherits the clean lines of the previous generation, but now subtly updated and given a more contemporary look. Smoother, simpler surfaces are up front, giving the vehicle its new character. They are emphasized by sportier-lòòking front lights, wîth new LED position lamps configured in a unique, signature stepped profile around the main light units. New lights are also introduced at the rear of the vehicle, incorporating LEDs for stop, tail and indicator lights.
The new front bumper has a larger cooling aperture and cleverly, the larger bumper actually improves vehicle aerodynamics by reducing drag thanks to its front wheel deflectors that help smooth the airflow from the front bumper around the front wheels.
A new, twin seven-spoke 19-inch wheel design debuts while a striking 10-spoke 20-inch wheel is available as a factory-fit option. Three new paint colors complete the exterior changes for LR4 - Nara Bronze, Bali Blue and Ipanema Sand.
'LR4 stays true to its clean, geometric, architecturally-inspired predecessors, while its new front bumper, lights and face wîth smoother lines and subtle curves, together wîth more color-coding, combine to enhance the overall impression of premium quality.'
-Gerry McGovern, Design Director
The new interior for LR4 combines smooth, flowing surfaces wîth significant reduction in the complexity and number of controls. It provides a much softer, more elegant all-round interior, but still in keeping wîth the vehicle's signature architectural thémé.
The new console is now inclined towards the driver, improving visibility and access to the controls. The Terrain ResponseTM control is now more prominently located at the front of the center console, making the cup-holder more accessible.
All models feature a new §teering wheel, wîth revised controls for driver information, remote audio controls, cruise control and the wheel's heating switch (if so equipped).
A choice of natural-finish woods, along wîth stitched and wrapped fascia, door casings and center console add to the handcrafted feel. There are also two new interior contrast colors, a mid-tone Nutmeg and a darker Arabica, complementing the existing Almond light color.
First and second-row seating have been redesigned wîth a new, extended front seat cushion profile to improve support and comfort. HSE models wîth the Premium Leather package also feature electrically adjustable side bolsters. The electric seat memory controls are relocated to the door casing.
New ambient white LED lighting casts subtle halos around the metal-plated interior door handles and pockets. The fascia and center console area, complete wîth soft-stitching and new switchgear also benefit from the interior mood lighting when vehicle lights are on.
'The interior of LR4 continues to offer the driver and passengers superb visibility and versatility. But the re-designed fascia and console architecture plus the use of premium materials, make the cabin a much more desirable place to be.'
-Gerry McGovern, Design Director
Technology made simple
Inside and out, the LR4 gains a raft of relevant new technology to improve the driving experience. A new hard-drive navigation system provides faster route calculation and improved reliability. This system adopts an easy-to-use navigation structure which now also features 'towards guidance.' This supplements the junction map and icon-based information wîth details of the actual road signage seen by the driver along the route.
The new Portable Audio Interface allows connectivity to an array of personal audio storage devices, ÚSB sticks and MP3 players. Their functions can be accessed and controlled through the dashboard's touch-screen system. One of the connectivity ports is a dedicated iPodTM point made exclusively by Land Rover. It ensures continued function in extreme driving conditions by helping to prevent the device coming loose from the socket.
A new 5-inch Thin Film Transistor (TFT) driver information LCD screen is also introduced wîth LR4. Sitting within the re-designed instrument cluster, this display ensures key information is communicated in a clean, simple and user-friendly manner.
And a purer, crisper radio sound is now available thanks to the introduction of HD Radio in the ÚS. Along wîth the fine listening experience come additional features such as song title and artist information.
'The LR4 is packed wîth easy-to-operate and useful features, not technology for technology's sake. The aim throughout is to simplify the operation, to help make journeys more relaxing and stress-free.'
-Stuart Frith, Chief Program Engineer
Cutting edge user-friendly technologies
Outside the vehicle, convenient and helpful new systems enhance safety and security.
The new front headlights incorporate available Automatic High Beam Assist. This can automatically switch on high beam headlights where external light levels are below the system's threshold. Importantly, the system is also designed to detect traffic ahead, and in a split second will automatically switch back to low beam to avoid dazzling others.
Five digital cameras make up the new available Surround Camera System, relaying to the touch-screen a near 360-degree view. The cameras, which support easier parking, towing and off-road maneuvering, function immediately as the vehicle is started, and have options for selecting and zooming in to assist wîth close quarter parking and wîth towing.
The 'tow assist' function (selected from the touch screen menu) helps perform accurate towing maneuvers. The wide views from the side cameras give a clear picture of the reversing trailer. The images are electronically manipulated to provide an undistorted view, wîth guide lines overlaid on the rear camera image to illustrate both the vehicle and trailer's trajectory. Specific characteristics such as type of trailer, number of axles and width guides can be fed into the system to fine-tune guidance ever further.
Another towing aid, Trailer Stability Assist, detects trailer oscillations by monitoring key vehicle behaviors, such as uninvited §teering movements and slight vehicle swing in response to trailer behavior. In these circumstances, the system can initiate engine torque reduction and braking interventions to bring the towing back under control. The LR4's sophisticated new remote key offers available Keyless Entry and Push Button start.
