    • The new, fourth generation of Land Rover's supremely versatile SUV gains a new name – Land Rover LR4 – to go with its powerful and highly efficient new LR-V8 engine, fresh exterior identity and more premium cabin. The class-leading breadth of capability is extended even further with dynamic improvements for both on-road and off-road driving, and Land Rover has added a battery of user-friendly new technologies and features.

    "The outgoing LR3 has well over 100 international awards to its name. But 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," says 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. The power and torque are both accessible across the entire rev range, to deliver immediate throttle response and effortless cruising ability, giving a 0-60 mph time of 7.5 seconds (0-100km/h in 7.6 seconds.)

    Land Rover's engineers have also transformed the LR4's on-road ride and handling, and even improved on the much acclaimed all-terrain capabilities of its predecessor. The comprehensive changes include new suspension components, revised steering, 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 with 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, with the revised front lower chin spoiler and new front wheel deflectors, help to reduce drag by increasing underfloor airflow, and LR4 is fitted with new 19-inch wheels and tires optimized for rolling resistance and improved tire wear.

    The interior is completely redesigned, with 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 more premium too, with smoother surfaces, softer materials and close attention to critical details such as stitching," says Gerry McGovern, Land Rover Design Director.

    New features available for the LR4 include a portable audio interface, available HD Radio, a new available five-camera 'surround' 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," says Phil Popham.

    * Maximum trailer weight with brakes; 7716lbs (3500 kg)

    All new, LR-V8 5.0L direct injection engine.

    "Our new 5.0-liter V8 was conceived from the onset with Land Rover models in mind. Designed with the emphasis on low-end torque, it is particularly suited to the LR4's wide range of capabilities both on and off road."
    Engine Group Chief Engineer, Malcolm Sandford.

    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 industry firsts.

    Designed entirely in-house by Jaguar Land Rover powertrain engineers, the
    LR-V8 5.0L is one of the most advanced engines ever built. The new LR-V8 develops 375 bhp and 375 lbs/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 ULEV2 (ultra low emissions vehicle) regulations.

    Direct injection – increased power and torque with optimized emissions
    A key feature of the new LR-V8 is an industry first, centrally-mounted, multi-hole, spray-guided fuel injection system, delivering fuel at a pressure of up to 150bar (2175 psi) directly to the cylinder.

    Fuel is delivered by twin, high pressure fuel pumps driven via an auxiliary shaft in the all new engine block. Delivery of fuel direct to the cylinder has substantially contributed to improved low speed dynamic response which is particularly useful off-road while adding to driving pleasure on-road. The charge cooling effects of the direct injection fuel system have allowed the compression ratio to be raised to 11.5:1.

    New variable camshaft timing system boosts engine torque, saves energy

    A new type of variable camshaft timing system (VCT) introduces another industry 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 engine oil pump has been reduced in size, saving energy and improving engine efficiency.

    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 higher than before, 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 clutch of the ZF HP-28 automatic transmission at lower speed. This reduces 'slip' in the hydraulic torque converter benefiting both fuel consumption and CO2 emissions. The higher torque at lower rpm also enables longer gearing for more economical cruising.

    The LR4 incorporates several other energy saving features too. At standstill, the idle speed of the V8 has been reduced from 700rpm to 600rpm yielding fuel savings 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.

    Strong and compact
    The new LR-V8 engine is built around a stiff, all new, aluminum block with 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 engine also has aluminum heads, with four-valves per cylinder and a strong, spheroidal-graphite cast-iron crankshaft with steel connecting rods. The cylinder heads and block are manufactured using recycled aluminum alloy for the first time, thus reducing the environmental impact of manufacturing the new engine.

    The new LR-V8 is also more compact than its predecessors. Overall engine length has been reduced through relocation of the oil pump within the engine architecture.

    LR-V8 5.0L naturally aspirated engine in short

    • 375 bhp and 375lbs/ft torque
    • 25 percent more power, 19 percent more torque than the existing 4.4-liter
    • Meets ULEV2 emissions regulations
    • Highly efficient multi-hole central spray-guided direct injection – industry first
    • Torque-actuated variable camshaft timing on all four cams – V8 engine industry first
    • Camshaft profile switching
    • Variable length inlet manifold optimizes power and torque
    • Reverse cooling improves engine efficiency and speeds cabin warm-up.
    • Class-leading, low-friction design features
    • 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, with base characteristics designed from the onset with the requirements of both brands in mind. High levels of torque and fast response from low revs perfectly suits both Jaguar and Land Rover DNA. The Jaguar version, the AJ-V8 Gen III, was recently launched in the new XF.

    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 with a mechanical cooling fan and, for packaging reasons, the inlet manifolds have been designed especially for the vehicle, while achieving the desired levels of noise vibration and harshness (NVH).

    For the Land Rover version, belt drives are waterproofed, as are the alternator, air conditioning compressor, power steering pump and starter motor. The engine is also tuned specifically to allow for the greater demands made on the LR4, particularly for towing and all-terrain driving.

    Responsive new transmission
    The LR-V8 is mated to the revised and super-smooth ZF HP28 6-speed automatic transmission. Its characteristics have been optimized by Land Rover engineers to provide class-leading response, with rapid and refined shifts. The dramatic enhancement of both power and torque low down the rev range on the new engine have made it possible to actuate the transmission's lock-up clutches much earlier in each gear, reducing slip through the hydraulic torque converter, so helping with the improvements in both efficiency and CO2 emissions.

    Dynamics transformed
    Major dynamic advances introduced for the LR4 include revised suspension architecture, improved steering, larger brakes and enhanced versions of Land Rover's award-winning Terrain ResponseTM and Hill Descent Control systems.
    The list of changes starts with new suspension knuckles, designed to reduce the separation between the suspension roll center and the vehicle's center of gravity (reduction of 1.65 inch (42mm) at the front and 2.44 inch (62mm) at the rear). This dramatically reduces the vehicle's natural body movements when cornering. These roll rates are further controlled by a stiffer and larger anti-roll bar.

    In addition, new bushings and new front and rear dampers enhance ride quality.
    The variable ratio steering rack is revised, complementing the improved ride quality by improving center line stability at high speed cruising and slightly increasing sensitivity at higher lock angles. This enhances the sense of driver involvement in high-speed maneuvers, and also increases precision for low speed control and off-roading.

    The redesigned front bumper also helps improve steering feel, as its new front wheel deflectors help reduce aerodynamic lift at the front of the vehicle by up to 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 performance system derived from the Range Rover Sport. It employs a 14.2-inch (360mm) ventilated front disc with a new, cast iron twin-piston sliding caliper – which serves to reduce the size of the front brake package while preserving its stiffness, which in turn helps achieve excellent pedal feel.

    At the rear, a single piston sliding caliper, now manufactured in aluminum to help reduce vehicle weight., operates on a 13.8-inch (350mm) ventilated disc,. An additional advance to the braking system is the new emergency brake light function. When the vehicle undertakes severe or emergency braking, the brake lights flash, to reduce the risk of rear end collisions.

    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 steering inputs from the driver. In extreme cases, automatic braking intervenes to reduce the vehicle speed, with the braking pressure level applied according to the steering inputs.

    Updates for award-winning Terrain ResponseTM and Hill Descent Control
    For LR4, 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, with five different settings to suit different terrains:

    • General driving
    • Grass/gravel/snow
    • Sand
    • 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 wheel-slip targets for the traction control system permit only very limited wheel-slip, helping to prevent the wheels digging down into the sand.
    New for LR4, 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 with 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
    "LR4 stays true to its clean, geometric, architecturally-inspired predecessors, while its new front bumper, lights and face with smoother lines and subtle curves, together with more color-coding, combine to enhance the overall impression of premium quality."
    Gerry McGovern, Design Director,

    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 premium, more contemporary look.

    Smoother, simpler surfaces are employed at the front, giving the vehicle its new character, emphasized by sportier looking front lights, with 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 LED stop, tail and indicator technology.

    The new front bumper has a larger cooling aperture to accommodate the new engine's greater power outputs. Cleverly, the larger bumper actually improves vehicle aerodynamics by reducing drag, thanks to its innovative front wheel deflectors that help smooth the airflow from the front bumper around the front wheels.
    A new, twin seven-spoke 19" wheel design is introduced on the LR4 to complement the existing seven-spoke 19" wheel and, for the first time, a new striking, 10-spoke 20" 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.

    All-new interior
    "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

    The new interior for LR4 combines smooth, flowing surfaces with significant reduction in the complexity and number of controls. It provides a much softer, more premium all-round interior ambience, but still in keeping with the vehicle's signature architectural theme.

    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 way for the cup-holder in a more accessible position, mid-way along the console.

    All models feature a new steering wheel, with revised switch layout for driver information, remote audio controls, cruise control and heated steering wheel.
    A choice of natural-finish woods, along with stitched and wrapped fascia, door casings and center console, add to the crafted bespoke feel. There are also two new interior contrast colors, a mid-tone Nutmeg and a darker Arabica, complementing the existing Almond light interior colorway.

    New seating is introduced for rows one and two, with a new, extended front seat cushion profile to improve support and seating comfort and, for the first time, the front seats feature height-adjustable head restraints in place of the traditional seat mounted grab handles. HSE vehicles specified with the Premium Leather pack also feature electrically adjustable seat bolsters, allowing front occupants to tailor their seating's support. For convenience, the electric seat memory controls are relocated to the door casing.

    New ambient lighting adds the finishing touch to the interior, with the introduction of white LED's to cast subtle halos around the metal-plated interior door handles and pockets. The fascia and center console area, complete with soft-stitching, and switchgear highlighted in "Noble" finishers, also benefit from the interior mood lighting when vehicle lights are on.

    Technology made simple
    The LR4 is packed with 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

    Inside and out, the LR4 gains a raft of relevant new technology, to improve the driving experience.

    The navigation system adopts an easy-to-use menu structure which now also features 'towards guidance'. This supplements the junction map and icon-based information with details of the actual road signage viewed by the driver along the route.

    The new available Portable Audio Interface allows connectivity to an array of personal audio storage devices, USB sticks and MP3 players, enabling the various devices' functions to be accessed and controlled via the fascia-mounted touch-screen system. One of the connectivity ports is a dedicated Apple i-PodTM point made exclusively by Land Rover, for continued functionality 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 with LR4. Sitting within the re-designed instrument cluster, the message center 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 US. Along with the fine listening experience, comes additional features such as song title and artist information.

    Cutting edge user-friendly technologies
    Outside the vehicle, convenient and relevant new systems enhance safety and security.

    The new front headlights incorporate available Automatic High Beam Assist technology. 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 preceding and approaching traffic, and in a split second will automatically switch back to low beam to avoid dazzling others.

    No less than 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 with close quarter parking and with towing.

    The 'tow assist' function (selected from the touch screen menu) helps perform accurate towing maneuvers. The wide fields of views on the side cameras give a clear view of the reversing trailer: the images are electronically manipulated to provide an undistorted view, with 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 enhance the system outputs.

    Another towing aid, Trailer Stability Assist, detects trailer oscillations by monitoring key vehicle behaviors, such as uninvited steering 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.

    And finally, the LR4's sophisticated new remote key offers available Keyless Entry and Push Button start.

Combine these enhancements with the contemporary style and luxury of the revised interior, and it's clear that the Range Rover Sport remains the only choice as the quintessential SUV sports tourer," says Phil Popham, Land Rover Managing Director.

    The Range Rover Sport reaffirms its status as the most exciting and dynamic member of the Land Rover range with a comprehensive package of engineering and design changes for the 2010 model year. The vehicle's stylish new appearance signals the transformation under the skin, which includes two powerful and efficient new engines - the LR-V8 naturally aspirated and LR-V8 5.0-liter Supercharged, enhanced levels of interior craftsmanship and refinement, and significant improvements to both on-road and off-road driving dynamics.

    A comprehensive program of chassis system modifications has transformed the Range Rover Sport's on-road dynamics, while also delivering a substantial improvement in its off-road capabilities.

    "The Range Rover Sport has generated a passionate following among customers who require the performance and refinement of a true sports tourer, but who value the formidable off-road ability of a Land Rover. Now that we have widened its range of capabilities even further, the following for the Range Rover Sport looks set to grow stronger still," says Phil Popham.

    "Both the new LR-V8 engines are suited to the sporting character of the Range Rover Sport, providing generous low-end torque and spirited performance along with levels of refinement worthy of the Range Rover name." says Phil Hodgkinson, Product Development Director.

    New engines deliver exceptional performance and refinement.
    The most significant changes on the 2010 Range Rover Sport are to its powertrains. The vehicle benefits from two powerful new engines: 510bhp LR-V8 5.0-liter supercharged and a 375bhp LR-V8 5.0 liter naturally aspirated engine.

    The LR-V8 engines are all-new and designed by the Jaguar Land Rover powertrain team using an impressive collection of state-of-the-art technologies. They were developed with an emphasis on delivering a smooth, refined and responsive performance, without a corresponding increase in fuel consumption. Both meet the stringent ULEV2 emissions standards.

    "We have given the Range Rover Sport two truly state-of-the-art new powertrains. Each engine – whether supercharged or naturally aspirated – delivers outstanding performance and refinement."
    Ron Lee, Group Chief Engineer, Powertrain.

    The performance of the all-new naturally aspirated LR-V8 is now a virtual-match for the outgoing 4.2L supercharged engine The new naturally aspirated vehicle completes the 0-60 mph sprint in 7.2 seconds (just 0.1 seconds off the pace of the outgoing supercharged unit). For those who want the ultimate performance Range Rover Sport, there is now the all-new LR-V8 5.0L Supercharged, which is propelled from rest to 60 mph in an impressive 5.9 seconds.

    The engines were developed in conjunction with Jaguar - the first time engines have been designed from the outset with the requirements of both brands in mind. Shared primary objectives included the highest possible torque and fast response from low revs.

    Although the basic engine architecture is the same for each brand, Land Rover engine requirements differ to satisfy demanding all-terrain needs . For example, they feature a deeper sump to accommodate the extreme tilting angles that Range Rover Sport may be subjected to off-road. In addition, belt drives are waterproofed, as are the alternator, air conditioning compressor, power steering pump and starter motor.

    All-new LR-V8 engines deliver outstanding performance and efficiency.
    • All-new 5.0-liter V8 design with 510bhp SAE supercharged and 375bhp SAE naturally aspirated versions.
    • 510bhp engine has 29 percent* more power and 12 percent* more torque than previous 4.2-liter supercharged engine.
    • 375bhp engine has 25 percent* more power and 19 percent* more torque than previous 4.4-liter engine.
    • Conforms to stringent ULEV2 emissions regulations.
    • Multi-hole central spray-guided direct injection is highly efficient – industry first.
    • High efficiency, 6th generation Eaton™ twin-vortex supercharger.
    • Torque-actuated variable camshaft timing on all four cams in V8 engine – industry first.
    • Camshaft profile switching and variable length inlet manifold optimizes power and torque.
    • Reverse cooling improves engine efficiency and speeds cabin warm-up.
    • Class-leading, low-friction design features.
    • Lightweight construction uses recycled materials.
    • 15,000 mile (24,000 km) service intervals.

    Direct injection – increased power and torque, low emissions.
    One of the key features of the new LR-V8 is an industry first, centrally-mounted, multi-hole, spray-guided fuel injection system, delivering fuel at a pressure of up to 150bar (2175 psi) directly to the cylinder. The positioning of the injectors ensures fuel is precisely delivered to the center of the combustion chamber, maximizing air-fuel mixing, and improving combustion control.

    Fuel is delivered by twin, high pressure fuel pumps driven via an auxiliary shaft in the all new engine block. Delivery of fuel direct to the cylinder has substantially contributed to improved low speed, dynamic response which is particularly useful off-road while adding to driving pleasure on-road. The charge cooling effects of the direct injection fuel system have allowed the compression ratio of the naturally aspirated engine to be raised to 11.5:1, further improving the engine economy.

    During the engine warm-up phase, the combustion system employs multiple injection mode strategies to deliver 50 percent more heat for fast catalyst warm-up and reduced emissions.

    New variable camshaft timing system boosts engine torque, saves energy.
    A new type of variable camshaft timing system (VCT) introduces another industry 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. This has allowed the engine oil pump to be reduced in size, saving energy and reducing fuel consumption.

    VCT units work independently on all four camshafts with 62 degrees of authority on the inlet cams and 50 degrees of authority on the exhaust cams. 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 higher than before with actuation rates in excess of 150 degrees per second. This delivers a more immediate engine response to the driver's demand.
    6th generation supercharger – quieter and more efficient.

    A sixth generation, Eaton™ twin vortex system (TVS) supercharger is fitted to the 510 bhp engine. A compact Roots-type unit it feeds air through twin intercoolers which in turn are water-cooled by their own cooling circuit. The high helix rotor design both improves the supercharger thermodynamic efficiency by 16 percent. It also improves noise quality to the point where the unit is now almost inaudible. The intercoolers reduce the temperature of the pressurised intake-air and so optimize power.

    The air intake has been radically redesigned compared to the previous V8. The intake air path is a direct feed to the supercharger inlet from the centrally mounted front throttle body. Air is delivered through twin air boxes which reduce flow loss and further increase efficiency. Mechanically, the new supercharger and its intercoolers are efficiently packaged in the V of the engine to deliver a low overall engine height.

    Warm up quickly with reverse flow cooling.
    The search for greater efficiency has in some areas led to a complete rethink of fundamental engine design concepts. An example is the innovative reverse flow cooling system which delivers thermodynamic and friction improvements. The new design means coolant is pumped through the cylinder heads before flowing through the block and returning to the radiator. Since the cylinder heads remain cooler, the knock threshold is pushed back allowing greater optimization of ignition timing for improved efficiency.

    In addition, the 22 kW oil to water heat exchanger, packaged at the core of the engine, transfers heat from the coolant to the lubricating oil during warm up, bringing the oil up to operating temperature 14 percent faster than the previous cooling system. This 'reverse flow' approach substantially improves fuel consumption in the crucial engine warm-up period and helps warm the cabin more quickly.

    Strong and compact.
    The new LR-V8 engines are built around a stiff, all new, aluminium block with 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, with 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.
    The new direct injection engine is more compact than its predecessor. Overall engine length has been reduced by relocation of the oil pump within the engine architecture.

    Reduced internal friction combats CO2.
    Internal friction, a major contributor to increased fuel consumption and CO2 emissions, has been targeted by careful design of the engines' components. As a result, the Range Rover Sport's new LR-V8 achieves another best in class, for crank train friction.

    All engine bearings were the subject of an extensive optimization, reducing friction without compromising reliability. Diamond-Like Carbon coating (DLC) has been used to reduce friction on the fuel pump tappets and a solid film lubricant has been used to coat the piston skirts.

    Land Rover has developed a unique, intelligent oil-pump pressure relief valve (PRV) which senses oil pressure deep in the engine's oil galleries to more accurately control oil pump delivery. As a result, oil pump frictional losses are reduced during the warm-up period.

    The engine has also been designed around a 5W-20 semi-synthetic oil. The new oil has a lower viscosity, primarily at low temperatures, reducing parasitic losses in the engines and contributing to an extension in service intervals from 7,500 miles to 15,000 miles or 12 months. The new LR-V8 engine is also fitted with an electronic oil level indicator for added peace of mind.

    Responsive new transmission.
    Both LR-V8 engines on the Range Rover Sport are mated to the revised and super-smooth ZF HP28 6-speed automatic transmission. Its characteristics have been optimized by Land Rover engineers to provide class-leading response, with 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, so helping with improvement in both fuel consumption and CO2 emissions.

    The transmission features an intelligent sport mode, which can sense and adapt transmission characteristics to particular driving styles. For the first time on the Range Rover Sport Supercharged, the driver can change gears manually with a steering wheel mounted paddle-shift.

    Transformed vehicle dynamics
    A comprehensive program of chassis refinements has been introduced to the Range Rover Sport for 2010. The enhancements transform the dynamics and handling characteristics of the vehicle, allowing drivers to fully exploit the capabilities of the new, high performance engine line-up.

    Adaptive Dynamics system
    The 2010 Range Rover Sport features a new Adaptive Dynamics System, which works in conjunction with the existing Dynamic Response system to enhance control of the vehicle's ride and handling.

    Land Rover has employed the world's first production system for this computer model-based predictive technology, which continually optimizes damper settings for the widest possible range of conditions. Conventional dampers are replaced by precision DampTronic Valve Technology™ damper units, which incorporate continually adjustable damper-valves.

    The predictive technology enables damper settings on each wheel to be continuously refined between 'soft', comfort oriented settings and 'hard', firm body control settings; damper pressure on each wheel is monitored 500 times per second. The system optimizes the vehicle's body and ride control, instantly responding to both the demands of the prevailing driving style and of the terrain encountered, in both on and off-road situations.
    Greater driver involvement through the wheel.

    Steering response is improved on the Range Rover Sport with the stiffening of the front suspension lower arm forward bushing, enhancing the sense of driver involvement with the vehicle at higher speeds.

    The revised variable ratio steering rack complements this by improving stability at high speed cruising – and increasing sensitivity at higher lock angles.

    Braking system gets more power and feel.
    The Range Rover Sport is equipped with a new braking system which has been comprehensively updated to provide enhanced stopping power and improved driver feel.

    The brakes for the naturally aspirated vehicle are modelled on the 4-piston opposed caliper performance system from the outgoing Supercharged model. The updated system employs 14.2-inch (360mm) ventilated front discs with new twin piston sliding cast-iron calipers for enhanced pedal feel. The rear features 13.8-inch (350mm) ventilated discs with lightweight aluminum single piston sliding calipers.

    The braking system for the Supercharged model has been developed in conjunction with performance brake specialists Brembo™. This system employs 15-inch (380mm) ventilated front discs with unique lightweight aluminum six-piston opposed action monoblock calipers. 14.3-inch (365mm) ventilated discs with single piston sliding calipers are fitted at the rear.

    Enhanced emergency braking.
    Models fitted with the Adaptive Cruise Control option also benefit from a new Advanced Emergency Brake Assist system, which is designed to detect the driver's responses to a potential emergency situation.

    Working in conjunction with the Forward Alert System's radar, Advanced Emergency Brake Assist primes the vehicle's braking system, and even initiates braking in extreme circumstances if a collision is judged possible. Valuable improvements in braking distances have been recorded in the testing of this system.

    Greater control and safety around corners.
    A refinement to the dynamic stability control system helps automatically slow the vehicle if taking a corner too fast, thus enhancing driver control.

    The system operates according to steering inputs from the driver. In extreme cases, automatic braking intervenes to help reduce the vehicle speed, with the braking pressure level applied according to the steering inputs.

    This feature is complemented by the new Roll Stability Control system, which is designed to intervene in the unlikely case of an extreme situation in which the possible onset of a rollover is detected. In such situations, the system is designed to take over and perform very rapid, wheel specific braking, to help reduce speed and marginally widen the cornering radius.

    In more extreme cases the system is designed to initiate marginal understeer by sharply increasing brake force on the outer wheels, again widening the turning radius.

    Updates for award-winning Terrain ResponseTM and Hill Descent Control.
    For the 2010 Range Rover Sport, Land Rover's award-winning Terrain ResponseTM system gains new features and refinements, further extending the vehicle's all-terrain capability.
    Most significantly, the Terrain ResponseTM system now includes a new 'Dynamic' program, designed for sporting on-road driving.

    Dynamic program delivers a responsive driving experience.
    When the driver selects the new Dynamic program, the Terrain Response™ system tailors the vehicles chassis and powertrain settings to deliver a more sporting and responsive driving experience. Tighter body control and quicker steering responses are achieved by adjustments to the Adaptive Dynamics system, while the accelerator pedal mapping, dynamic stability control system and gear-change settings are also given more sporting characteristics.

    The Dynamic program has also been specially tuned to take advantage of chassis changes to the supercharged model which is designed to deliver improved driver confidence at higher speeds. The changes include a 20% stiffer rear roll control bar, and further revisions to the steering system, suspension bushings and wheel alignment settings.

    Coping with tougher conditions.
    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 wheel-slip targets for the traction control system permit only very limited initial wheel-slip, helping to prevent the wheels digging down into the sand.

    New for Range Rover Sport, revisions to the rock crawl program improve brake and traction control response times, helping to reduce the vehicle's wheels rolling in an unintended direction when traversing boulders, and giving a more composed drive through rocky terrain.

    Land Rover's much-acclaimed Hill Descent Control system is enhanced on the latest Range Rover Sport with 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.

    More sporting design for a more sporting vehicle.
    "We have given the Range Rover Sport a cleaner, more muscular appearance which is the perfect complement to its new range of high performance engines. Striking new signature LED headlamps, a two-bar grille and a larger air intake create a bold new frontal graphic which helps to reinforce the vehicle's athletic stance."
    Design director, Gerry McGovern

    The new design theme for the 2010 Range Rover Sport emphasises its position as the most dynamic model in the Land Rover range, creating a sporting, cleaner and more sculpted appearance.

    At the front, new signature LED headlamps provide a technical focal point, and feature Range Rover inspired interlocking circle lamps. With a new two-bar grille and larger air intake, the vehicle's frontal graphic is much more slim, athletic and low-slung.

    The new front bumper blends with redesigned front fenders to form a simple, sculpted surface, offering improved aerodynamics and a lower, more sporting visual stance.

    The side view of the vehicle features new two-stripe LED indicators, along with redesigned two-section fender vents. Color coded door mirrors complete the visual changes.

    At the rear, Range Rover inspired light clusters create a fresh new look, while the smooth and sculpted bumper design mirrors the style of the front-end.

    New front wheel deflectors help reduce drag and new 19 and 20-inch tires are available on Range Rover Sport, optimized for rolling resistance and improved tire wear.

    Premium interior environment.
    The interior has been comprehensively redesigned, and features significantly improved standards of quality and craftsmanship.

    The cabin retains its popular cockpit feel but incorporates higher quality materials, sumptuous soft-touch finishes and superb detailing throughout the interior. Leather is used extensively on major surfaces, in a wider choice of colors. To create a more sporting feel, rich dark shades 'sandwich' narrow sections in lighter tones, and the effect is completed by a generous selection of stylish wood finishes.

    The soft-touch fascia is all new, with a smooth and clean-looking design that can be wrapped in stitched, premium grade European leather. It features an architectural beam that runs across the width of the cabin, supported by natural wood finish pillars.

    To enhance the clean look of the interior, the fascia now has 50 percent fewer switches; the switches themselves now feature noble accents. The signature roller-shutter cup-holder cover is now finished in a high-quality metallic sheen.

    There are new seats front and rear, which feature a deeper, more sculpted shape; electrically adjustable side bolsters are available on the front seats for the first time.

    New ambient lighting adds to the premium qualities of the cabin, with the introduction of white LEDs to cast subtle halos around interior door handles and pockets, as well as on the fascia and center console area.

    Cutting edge vehicle technologies.
    "The 2010 Range Rover Sport features a host of new technologies that will really enhance the driving and ownership experience for our customers. But in each case the complexity is hidden from view – we've made every system intuitive and simple to use."
    Stuart Frith, Chief Program Engineer.

    The latest Range Rover Sport incorporates a comprehensive range of state-of-the-art technologies, designed to improve comfort, convenience, safety and security for all vehicle occupants.

    Infotainment systems and displays.
    A new hard-drive navigation system provides faster route calculation and improved system reliability.
    The navigation system adopts an easy-to-use navigation structure which now also features 'towards guidance.' This supplements the junction map and icon-based information with details of the actual road signage viewed by the driver along the route.

    The new Portable Audio Interface allows connectivity to an array of personal audio storage devices, USB sticks and MP3 players, enabling the various devices' functions to be accessed and controlled via the facia-mounted touch-screen system. One of the connectivity ports is a dedicated iPodTM point made exclusively by Land Rover, for continued functionality 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 screen is also introduced with the 2010 Range Rover Sport. Sitting within the instrument cluster, the message center display ensures key information is communicated in a clean, simple and user-friendly manner.

    Improving safety and security.
    Outside the vehicle, convenient and relevant new systems enhance safety and security.
    The Range Rover Sport now offers a sophisticated new remote key which offers both Keyless Entry and Push Button Start.

    A new Surround Camera System supports easier parking and towing. It features five digital cameras which relay a near 360-degree view to the touch-screen display. The cameras function immediately as the vehicle is started, and have options for selecting and zooming in to assist with close quarter parking and with towing.

    The patented reverse 'tow assist' and tow hitch assist functions (selected from the touch screen menu) help perform accurate towing maneuvers. The wide fields of vision on the side cameras give a clear view of the reversing trailer and the images are electronically manipulated to provide an undistorted view. Guide lines overlaid on the rear camera image illustrate both the vehicle and trailer's trajectory and these move in line with steering inputs, making it easier for the driver to predict where the trailer will move to, before performing the reversing maneuver.

    Specific characteristics such as type of trailer, number of axles and width guides can be fed into the system to enhance the system outputs.

    The Range Rover Sport's new LED front headlights incorporate available High Beam Assist technology. 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 preceding and approaching traffic, and in a split second will automatically switch back to low beam to avoid dazzling others.

    Powerful new engines, advanced interior technologies and enhanced driving dynamics reinforce the position of the 2010 Range Rover as Land Rover's most complete luxury all-terrain vehicle. Land Rover's flagship has been comprehensively updated to deliver more refined and efficient performance, along with the ultimate in interior comfort and craftsmanship.

    "The 2010 Range Rover is a considerable step forward for what is already regarded as the one of the world's most complete luxury vehicles. New engines deliver formidable power, efficiency and customary Range Rover refinement, and new technologies, such as the 12" TFT instrument cluster. The 2010 Range Rover remains the benchmark and continues to set the pace in its segment," says Phil Popham, Land Rover Managing Director.

    The 2010 Range Rover has two brand new 5.0-liter LR-V8 engines – the top of the range 510 bhp supercharged unit, and the 375 bhp naturally aspirated version. Both engines were developed in-house by the Jaguar Land Rover powertrain team, with the requirements of the Range Rover in mind from day one.

    The LR-V8 engines have been developed to deliver more power and refinement but without a corresponding increase in consumption and emissions. The result is a pair of lightweight direct fuel injection engines with class-leading efficiency, which provide significantly more usable low end torque and superior dynamic responses without compromising power at higher RPM. Both engines are compliant with stringent U.S. ULEV2 emissions regulations.

    The performance of the all-new naturally aspirated LR-V8 is now a virtual-match for the outgoing 4.2L supercharged engine. The new naturally aspirated vehicle completes the 0-60 mph sprint in 7.2 seconds (just 0.1 seconds off the pace of the outgoing supercharged unit). For those who want the ultimate performance Range Rover, there is now the all-new LR-V8 5.0L Supercharged, which is propelled from rest to 60 mph in an impressive 5.9 seconds.

    The 2010 improvements include subtle exterior revisions, featuring discrete changes to the headlights, grille and bumper which enhance the classic Range Rover design with more contemporary detailing. The interior benefits from more luxurious materials and finishes which add further refinements to the premium cabin ambiance.

    More significantly, the 2010 Range Rover uses some revolutionary new interior technologies which enhance the experience for both driver and passengers alike.

    A dramatic innovation is found in the instrument cluster. Here, traditional physical instruments are replaced by a 12" Thin Film Transistor screen which presents all essential driver information via cleverly designed 'virtual' dials and graphical displays.

    "The new display technology used by the 2010 Range Rover is a major advance. It gives us tremendous flexibility in presenting information, so that the driver gets precisely the data they require, in all driving conditions," explains Nick Rogers, Chief Engineer, New Vehicle Architecture.

    The vehicle incorporates state-of-the-art Adaptive Dynamics technology (optional on LR-V8 naturally aspirated) to further improve the Range Rover's peerless ride quality. All-terrain performance is also enhanced by updates to the Terrain Response™ and Stability Control systems.

    To complete the package, the 2010 Range Rover benefits from a series of enhanced active safety aids including Adaptive Cruise Control, Emergency Brake Assist, Blind Spot Monitoring, available Automatic High Beam Assist (AHBA) and an available surround camera system.

    "The Range Rover remains the consummate luxury SUV . Its combination of unrivalled all-terrain performance with the ultimate in comfort and refinement, remains a clear industry benchmark," says Phil Popham.

    "Both versions of the V8 return impressive levels of power and torque combined with optimized fuel consumption and emissions – the supercharged 5.0-liter engine is one of the most fuel efficient in its class. As well as stunning top-end performance, they also deliver the low-end flexibility essential for real-world driving."

    Malcolm Sandford, Engine Group Chief Engineer, Land Rover

    The Range Rover gets an all-new engine line up with a choice of two 5.0-liter LR-V8 units in supercharged and naturally aspirated guise. The two engines were developed in conjunction with Jaguar, which is the first time engines have been designed from the onset with the requirements of both brands in mind. Shared primary objectives included the highest possible torque and fast response from low revs.

    Although the basic engine architecture of both engines is the same for each brand, Land Rover engine requirements differ to satisfy demanding all-terrain needs. For example, the engines feature a deeper sump to accommodate the extreme tilting angles experienced when driving the Range Rover off-road, and to accommodate the front differential which attaches to it. In addition, belt drives are waterproofed, as are the alternator, air conditioning compressor, power steering pump and starter motor.

    The supremely powerful supercharged LR-V8 delivers 510 bhp and 461 lb/ft of torque, while the naturally aspirated version produces 375 bhp and 375 lb/ft of torque. Two of the most advanced engines ever built, they are packed with innovative features to ensure that they are also two of the most efficient in their class.

    Both derivatives were developed with an emphasis on delivering a smooth, refined and responsive driver experience, with excellent power characteristics. Compared to the current 4.2-liter V8 the supercharged engine increases power and torque outputs by 29 percent and 12 percent respectively.

    Yet when it comes to regulated emissions both engines are incredibly clean, meeting the stringent American ULEV2 (ultra low emissions vehicle) regulations.

    Direct injection – increased power and torque, lower emissions

    One of the key features of the new LR-V8 is an industry first, centrally-mounted, multi-hole, spray-guided fuel injection system, delivering fuel at a pressure of up to 150bar (2,175 psi) directly to the cylinder. The positioning of the injectors ensures fuel is precisely delivered to the center of the combustion chamber, maximizing air-fuel mixing, and improving combustion control.

    Fuel is delivered by twin, high pressure fuel pumps driven via an auxiliary shaft in the all new engine block. Delivery of fuel direct to the cylinder has substantially contributed to improved low speed, dynamic response which is particularly useful off-road while adding to driving pleasure on-road. The charge cooling effects of the direct injection fuel system have allowed the compression ratio of the naturally aspirated engine to be raised to 11.5:1, further improving the engine efficiency.

    During the engine warm-up phase, the combustion system employs multiple injection mode strategies to deliver 50 percent more heat for fast catalyst warm-up and reduced emissions.

    6th generation Eaton™ supercharger – quieter and more efficient.

    A sixth generation, Eaton™ twin vortex system (TVS) supercharger is fitted to the 510 bhp engine. A compact Roots-type unit, it feeds air through twin intercoolers which in turn are water-cooled by their own cooling circuit. The high helix rotor design both improves the supercharger thermodynamic efficiency and improves noise quality to the point where the unit is virtually inaudible. The intercoolers reduce the temperature of the pressurized intake-air and so optimize power.

    The air intake has been radically redesigned compared to the previous V8. The intake air path is a direct feed to the supercharger inlet from the centrally mounted front throttle body. Air is delivered through twin air boxes which reduce flow loss and further increase efficiency. Mechanically, the new supercharger and its intercoolers are efficiently packaged in the V of the engine to deliver a low overall engine height.

    New variable camshaft timing system boosts engine torque, saves energy

    A new type of variable camshaft timing system (VCT) on the V8 engine introduces another industry 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. This has allowed the engine oil pump to be reduced in size, saving energy and reducing fuel consumption.

    VCT units work independently on all four camshafts with 62 degrees of authority on the inlet cams and 50 degrees of authority on the exhaust cams. Timing is optimized by the engine control unit for torque, power and efficiency at every point in the engine's speed range.

    The response rate of the new VCT units is 25 percent quicker than before with actuation rates in excess of 250 degrees per second. This delivers a more immediate engine response to the driver's demand.

    Camshaft profile switching – flexibility with performance

    In addition to VCT, the naturally aspirated LR-V8 is also equipped with camshaft profile switching (CPS) on the inlet camshaft. Depending on the engine's running conditions and the requirements of the driver, the CPS will switch between a profile that is ideal for low speed driving, and another which gives increased valve lift for high performance. This feature helps endow the Range Rover with ample low end torque in demanding terrain, yet fully exploits the potential of the 5.0-liter V8 when conditions allow.

    An hydraulically-actuated two-piece tappet switches between profiles on the tri-lobe camshaft altering both the lift and duration. The cam lobe profile selected for engine speeds below 3000 rpm has a duration of 214 degrees and lifts the valves 5.5mm. This optimizes gas velocity for improved low-speed torque and reduces valve train friction for improved fuel efficiency. For high-speed driving, CPS switches to a cam lobe with a duration of 250 degrees and valve-lift of 10.5mm, allowing greater air flow into the engine for high power.

    Variable Inlet Manifold (VIM) optimizes power and torque

    Complementing VCT and CPS on the naturally aspirated LR-V8 is a new variable inlet manifold (VIM) which can vary the length of its eight inlet tracts to optimize power and torque throughout the rev range. As a consequence, the engine can develop the maximum possible low-end torque yet breathe well enough to develop the maximum possible power at high rpm. Vacuum operated actuators open valves to select a longer, 680mm, inlet tract at low revs, increasing the rate of both the airflow and the engine torque. As the revs climb beyond 4,700rpm, the actuators select a shorter, 350mm, path allowing a greater volume of air into the engine for higher power. The actuator position is continually optimized by the engine control unit for torque and efficiency throughout the engine speed range.

    Warm up quickly with reverse flow cooling

    The search for greater efficiency has in some areas led to a complete rethink of fundamental engine design concepts. An example is the innovative reverse flow cooling system which delivers thermodynamic and friction improvements. The new design means coolant is pumped through the cylinder heads before flowing through the block and returning to the radiator. Since the cylinder heads remain cooler, the knock threshold is pushed back allowing greater optimization of ignition timing for improved efficiency.

    In addition, the 22 kW oil to water heat exchanger, packaged at the core of the engine, transfers heat from the coolant to the lubricating oil during warm up, bringing the oil up to operating temperature 14 percent faster than the previous cooling system. This 'reverse flow' approach substantially improves fuel consumption in the crucial engine warm-up period and helps warm the cabin more quickly.

    Strong and compact

    The new LR-V8 engines are built around a stiff, all new, aluminum block with 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 aluminum heads, with 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 engine.

    The new direct injection engines are more compact than their predecessors. Overall engine length has been reduced by relocation of the oil pump within the engine architecture. Overall engine weight (fully dressed with all ancillaries) is 210kg for the naturally aspirated unit and 236kg for the supercharged unit.

    Reduced internal friction combats CO2

    Internal friction, a major contributor to increased fuel consumption and CO2 emissions, has been targeted by careful design of the engines' components. As a result, the Range Rover's new LR-V8s achieve another best in class for crank train friction.

    All engine bearings were the subject of an extensive optimization, reducing friction without compromising reliability. Diamond-Like Carbon Coating (DLC) has been used to reduce friction on the fuel pump tappets and a solid film lubricant has been used to coat the piston skirts.

    Land Rover has developed a unique, intelligent oil-pump pressure relief valve (PRV) which senses oil pressure deep in the engine's oil galleries to more accurately control oil pump delivery. As a result, oil pump frictional losses are reduced during the warm-up period.

    The engines have also been designed around a 5W-20 synthetic oil. The new oil has a lower viscosity, primarily at low temperatures, reducing parasitic losses in the engines and contributing to an extension in service intervals from 7,500 miles to 15,000 miles or 12 months. The new LR-V8 engines are also fitted with an electronic dipstick for added peace of mind.

    Responsive new transmission

    The 2010 Range Rover's new engines are mated to the revised and super-smooth ZF HP28 6-speed automatic transmission. Its characteristics have been optimized by Land Rover engineers to provide 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, so helping with the improvements in both fuel consumption and CO2 emissions.

    The transmission features an intelligent sport mode, which can sense and adapt transmission characteristics to particular driving styles.

    Enhanced vehicle dynamics – both on- and off-road

    The 2010 Range Rover benefits from a comprehensive program of refinements to its vehicle dynamics. The enhancements include features that will improve ride and handling during on-road driving, plus a series of measures that give greater capabilities when driving off-road or when towing.

    Unique adaptive dynamics system improves ride and control

    The 2010 Range Rover has an advanced new Adaptive Dynamics system which further improves the Range Rover's peerless ride quality with greater refinement and superior body control.

    It is the world's first production system to employ model-based predictive technology that continually optimizes damper settings for the widest possible range of conditions. Conventional dampers are replaced by precision DampTronic Valve Technology™ damper units, which incorporate continually adjustable damper valves.

    The predictive technology enables damper settings on each wheel to be continuously refined between 'soft', comfort oriented settings and 'hard', firm body control settings; damper pressure on each wheel is monitored 500 times per second. The system optimizes the vehicle's body and ride control, instantly responding to both the demands of the prevailing driving style and of the terrain encountered, in both on- and off-road situations.

    Braking system gets more power and feel

    The Range Rover is equipped with a new braking system which has been comprehensively updated to provide enhanced stopping power and improved driver feel.

    The brakes for the naturally aspirated vehicle are based on the four-piston opposed caliper performance system from the outgoing Supercharged model. The updated system employs 14.2-inch (360mm) ventilated front discs with new twin piston cast-iron sliding calipers for enhanced pedal feel.

    The rear features 13.8-inch (350mm) ventilated discs with lightweight aluminum single piston sliding calipers.

    The braking system for the Supercharged model has been developed with performance brake specialists Brembo™. This system employs 15-inch (380mm) ventilated front discs with unique lightweight aluminum six-piston opposed action monoblock calipers. 14.3-inch (365mm) ventilated discs with single-piston sliding calipers are fitted at the rear.

    Greater control and safety around corners

    A refinement to the stability control system helps automatically slow the vehicle if taking a corner too fast, thus enhancing driver control.

    Enhanced Dynamic Stability Control interfaces with the brake modulator and powertrain control module. If the speed is too great for engine torque reduction to control the vehicle, automatic braking intervenes to reduce the vehicle speed, with braking pressure applied according to the severity of the situation. At decelerations in excess of 0.7g the brake lights are automatically applied to warn following traffic.

    This feature is complemented by the new Roll Stability Control system, which is designed to intervene in the unlikely case of an extreme situation in which the possible onset of a rollover is detected. In such situations, the system is designed to take over and perform very rapid, wheel specific braking, to help reduce speed and marginally widen the cornering radius.

    Improved performance and stability off-road

    The award winning Terrain Response™ system is subject to a whole series of improvements, including enhanced capabilities when tackling challenging terrain like sand or large rocks.

    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 wheel-slip targets for the traction control system permit only very limited initial wheel-slip, helping to prevent the wheels digging down into the sand.

    New for Range Rover, revisions to the rock crawl program improve brake and traction control response times, helping to reduce the wheels rolling in an unintended direction when traversing boulders, and giving a more composed drive through rocky terrain.

    Land Rover's much-acclaimed Hill Descent Control system is enhanced on the latest Range Rover with the addition of Gradient Release Control. This inhibits the initial rate of acceleration for descending very steep inclines, to increase control when braking is released at extreme angles.

    More stable towing

    For safer and more stable towing, the 2010 Range Rover incorporates Trailer Stability Assist. This system detects trailer oscillations by monitoring key vehicle behaviors, such as uninvited steering movements and slight vehicle swing in response to trailer behavior. In these circumstances, the system can initiate engine torque reduction and braking interventions to help bring the towing back under control.

    Classic Range Rover style with contemporary details

    "We have introduced a number of more contemporary design elements on the 2010 Range Rover, but have been careful not to disturb the vehicle's classic proportions and unique silhouette. The refined detailing and cleaner surfaces of the 2010 model retain the timeless and noble qualities which are traditional hallmarks of Range Rover design."

    Design Director, Gerry McGovern

    The 2010 Range Rover features subtle revisions to the exterior design, introducing some attractive new design elements which enhance the classic Range Rover style with more contemporary detailing.

    New headlights feature the Range Rover's trademark inter-locking circle design, but are more clearly visible, day or night, with LED lamp technology. The headlights are marginally shallower, and 'bookend' a deeper, more upright mesh grille.

    A new bumper completes the smoother, more sculpted front end, reflecting the clean surface integration which is now characteristic of Range Rover design. The fog lamps are relocated from the bumper skin to the lower front air-intake.

    The side of the vehicle features new 'three-stripe' LED indicators and redesigned three-section fender vents. The same design theme is adopted by the rear LED light clusters, which incorporate 'three-stripe' directional indicators.

    Interior showcases luxurious materials and revolutionary technologies

    Superbly crafted new materials and some revolutionary display technologies help to improve a cabin that is already widely regarded as one of the automotive world's finest.

    To further enhance the premium interior ambience, the 2010 Range Rover introduces new luxury grade European leather trim for the headlining, pillar and door casings. Fascia buttons now feature a satin chrome-plated finish, which are beautifully highlighted by the Range Rover's upgraded waterfall interior lighting. High quality satin black and natural wood finishes complete the sumptuous feel of the interior architecture.

    'Virtual' dials and graphic displays replace traditional instruments

    One of the major innovations in the 2010 Range Rover is found in the instrument cluster. Here, traditional physical instruments are replaced by a 12" Thin Film Transistor screen which presents all essential driver information via cleverly designed 'virtual' dials and graphical displays.

    The system's message center (the area between rev counter and speedometer) can be customized by the driver to display personal prioritized information, from system warnings, outside temperature and vehicle information to less critical data such as audio and telephone displays.

    The message center also relays off-road information, such as steering angle, wheel articulation, suspension settings and Terrain Response™ settings.

    Fingertip control of settings and menus on the TFT screen is provided by an updated steering wheel which incorporates a five-way controller.

    Update Touch-screen Technology

    The touch-screen retains all the functionality of the previous display, but the graphics and menus have been redesigned for easier and more intuitive operation, allowing the number of 'hard' buttons around the screen to be reduced by a third. As before, functions such as satellite navigation, DVD video, and audio systems can be controlled via the display.

    An updated voice control system with enhanced voice recognition software complements the touch screen, and can be used to control a range of entertainment and comfort features such as the audio system and climate control.

    Advanced vehicle technologies enhance convenience and safety

    "The technologies built into the 2010 Range Rover are designed to improve convenience and safety, reducing the stress of driving in modern motoring conditions, on all terrains. With technology sharing the workload, the result is a more relaxed, alert driver."

    Paul Walker, Chief Program Engineer

    The 2010 Range Rover incorporates a comprehensive selection of advanced vehicle technologies which enhance convenience and improve active safety for the driver.

    Adaptive Cruise Control

    The 2010 Range Rover features Land Rover's Adaptive Cruise Control system (ACC) for the first time. The system employs a 76GHz scanning radar to locate vehicles moving in the same direction, and is designed to maintain optimal vehicle speed by using acceleration, deceleration and braking to keep a specified distance from the traffic ahead.

    ACC comes with four driver-selectable settings, designed to suit individual driving style and traffic / road conditions. The driver can select a 'headway' of between 1 to 2.2 seconds, with a default setting of 1.8 seconds; this equates to a 50 meter distance from the vehicle ahead when travelling at 62 mph (100km/h). The system is designed to operate at speeds of up to 112 mph (180km/h).

    Vehicles fitted with the ACC system also benefit from a new Advanced Emergency Brake Assist system. Working in conjunction with the Forward Alert System's radar, this primes the vehicle's braking system, and even initiates braking in extreme circumstances if a collision is judged possible. Valuable improvements in braking distances have been recorded in the testing of this system.

    Updated infotainment systems

    A new hard-drive navigation system provides faster route calculation, larger area map coverage and improved reliability. The navigation system adopts an improved navigation structure which now also features 'towards guidance'. This supplements the junction map and icon-based information with details of the actual road signage viewed by the driver along the route.

    The available new Portable Audio Interface allows connectivity to an array of personal audio storage devices, USB sticks and MP3 players, enabling the various devices' functions to be accessed and controlled via the fascia-mounted touch-screen system. One of the connectivity ports is a dedicated iPodTM point made exclusively by Land Rover, for continued functionality in extreme driving conditions, by helping to prevent the device coming loose from the socket.

    And a purer, crisper radio sound is now available thanks to the introduction of an optional HD Radio in the U.S. Along with the fine listening experience, come additional features such as song title and artist information.

    Enhanced safety and visibility

    The 2010 Range Rover has a blind spot monitoring system available which uses side-mounted radar sensors to detect vehicles and other solid objects in the vehicle's blind spot area. If an object is detected, a bright amber warning icon is illuminated in the driver's door mirror.

    Available as an option, is a new Surround Camera system which supports easier parking, towing and off-road maneuvering. It features five digital cameras which relay a near 360-degree view to the touch-screen display. The cameras function immediately as the vehicle is started, and have options for selecting and zooming in to assist with close quarter parking and with towing.

    The patented 'reverse tow assist' function (selected from the touch-screen menu) helps perform accurate towing maneuvers. The wide fields of view on the side cameras give a clear view of the reversing trailer and the images are electronically manipulated to provide an undistorted view. Guide lines overlaid on the rear camera image illustrate both the vehicle and trailer's trajectory and these move in line with steering inputs, making it easier for the driver to predict where the trailer will move to, before performing the reversing maneuver.

    Specific characteristics such as type of trailer, number of axles and width guides can be fed into the system to enhance the system outputs.

    The Range Rover's front headlights incorporate optional high beam assist technology. 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 preceding and approaching traffic, and in a split second will automatically switch back to low beam to avoid dazzling others.

    All-new electrical architecture

    The performance of many of the 2010 Range Rover's advanced technologies is enhanced by a completely new electrical architecture which supports more efficient integration between the various systems. Information is shared between electronic components via a high speed Controller Area Network (CAN), with a fiber optic Media Orientated System Transport (MOST) network controlling the modules of the infotainment system, enhancing reliability and saving weight.
