-- Refined, efficient and powerful new LR-V8 5.0L direct injection engine
-- Impressive 375 lb/ft torque and 375 bhp
-- ULEV2 compliant
-- On-road dynamics transformed by comprehensive chassis system developments and a new super-smooth 6-speed adaptive transmission
-- Updates to Land Rover's award-winning Terrain ResponseTM system reinforce class-leading all-terrain performance
-- Fresh exterior design includes smoother new front end and revised lights, including LEDs
-- All-new interior design delivers a more premium and functional five and optional seven-seat space
-- User-friendly new features include available Surround Camera system, Gradient Release Control, Tow Assist, available Automatic High Beam Assist, and Keyless Entry, Push Button start.-- 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.

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.
