The Range Rover’s look is timeless. The original design lasted relatively untouched for 26 years, and the only reason why it was redone for the third generation was to get the RR’s design back to the looking like the original. So when major updates are announced for 2010, look closely. This facelift includes a revised bumper with relocated fog lamps, new grille and new headlamps. The overall impression help the Range Rover closer to achieve its very British goal of simple elegance. The interior’s appearanc has also been upgraded and includes a new GPS navigation system. The instrument cluster in front of the driver has been replaced with a Thin Film Transistor screen to better organize driver information. The real change comes in the engine compartment. Land Rover is taking advantage of the newly enlarged 5.0-liter V8 engine from Jaguar. Now the Range Rover will be available with 375 hp or 510 hp in supercharged form — that’s a 75 hp and 110 hp bump over the previous engine lineup. Press release after the jump. Press release 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 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 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.
“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 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. Direct injection – increased power and torque, lower emissionsOne 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. 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. New variable camshaft timing system boosts engine torque, saves energyA 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. Camshaft profile switching – flexibility with performanceIn 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. Variable Inlet Manifold (VIM) optimizes power and torqueComplementing 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 coolingThe 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. Strong and compactThe 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. Reduced internal friction combats CO2Internal 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. 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. Responsive new transmissionThe 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. Enhanced vehicle dynamics – both on- and off-roadThe 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 controlThe 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. Braking system gets more power and feelThe Range Rover is equipped with a new braking system which has been comprehensively updated to provide enhanced stopping power and improved driver feel. Greater control and safety around cornersA refinement to the stability control system helps automatically slow the vehicle if taking a corner too fast, thus enhancing driver control. 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-roadThe 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. 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 towingFor 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. 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 technologiesSuperbly 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 instrumentsOne 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. Update Touch-screen TechnologyThe 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. 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 Adaptive Cruise ControlThe 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. Updated infotainment systemsA 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. Enhanced safety and visibilityThe 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. 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. All-new electrical architectureThe 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. 1 comments: Range Rover
