High-Speed Luxury. Packed With Technology RANGE ROVER SPORT - IN BRIEF Exciting Design DESIGN "The Range Rover Sport looks like it's going fast - even when it's standing still." That was one of design director Geoff Upex's priorities when the vehicle was conceived. "When people see the vehicle they should want to get in and drive it immediately," says Upex. "It had to look dynamic and exciting, and be utterly tempting. We wanted a compact, muscular, hewn-from-the-solid design that promised great power." It also had to look like a member of the Land Rover family. But with a sporting attitude. "We used many of the classic Range Rover design cues, like the floating roof - achieved by the blacked-out roof pillars - but treated them in a different way," says Upex. "Range Rover Sport is a less formal vehicle and has more emotion. It had to look more dynamic, more active, and be more aggressive. The design is less geometric and has more flow: it is more rounded, more compact, tighter and more tapered. That's the reason why this vehicle does away with the Range Rover's bonnet castellations. We wanted a smoother, more aerodynamic look." The windscreen is steeply raked, and the roof is lower than on other Land Rovers. The glass area is shallower and the rear D-pillars are faster. Wheels are pushed out to the corners and are big - 20-inch on the supercharged model - to fill the wheel arches and convey the vehicle's sporty character. Bigger tyres also offer more grip. There are front and rear spoilers plus side skirts. They not only increase the sporty character of the styling, but also improve high-speed stability and the aerodynamics. The new Range Rover Sport is one of the world's most aerodynamically efficient SUVs, with a drag coefficient of 0.37 (0.36 on some diesel models). The aerodynamic aids have also been designed with off-roading in mind. The front spoiler is made from rubber, so can withstand knocks from rocks and ruts, and the side skirts not only improve stability and the drag coefficient, but also stop mud splattering the sills and prevent stone chips to the paintwork. The rear of the roof is extended by a tail spoiler. This appears to lengthen the roof line and gives a sportier appearance, as well as forming a 'flick line' to extend the airflow rearward. This reduces wake turbulence and improves the aerodynamics. Flush-fitting glass and smooth surfacing around the lights further improve the vehicle's ability to cleave the air. The Range Rover Sport has a single tailgate with a separate lifting glass. Unlike the Range Rover's split tailgate - which necessitates a flat rear end - the Range Rover Sport has a rounded rear. This gives the vehicle a more compact, tighter look and also helps smooth the airflow around the rear of the vehicle. The nose of the vehicle bears a strong resemblance to the acclaimed Range Stormer concept car, which previewed the Range Rover Sport when unveiled at the 2004 North American International Auto Show in Detroit. As with Range Stormer, the Range Rover Sport offers a powerful supercharged V8, which demands the efficient passage of air around the engine. The perforated mesh grille helps maximise airflow into the engine bay, while one of the two side vents helps get air out of the bonnet area quickly. The other side vent is an intake for the engine induction system. The headlight cluster continues the latest Land Rover family look but is slimmer than those used on the Range Rover and Discovery 3/LR3. It also features adaptive headlights, which swivel with the direction of travel to illuminate the road ahead. Bi-xenon lights are available for even better illumination and lower maintenance. Rear lights are also distinctively styled. Headlamp mouldings, front grille, vents, door handles and tailgate appliqué all have 'Tungsten' metal finish. The supercharged version is distinguished by the use of brightwork for the perforated grille and side air intakes, black and silver Land Rover badges, 20-inch wheels and twin stainless steel exhausts. POWERTRAIN Three light, compact engines are offered in the Range Rover Sport (depending on market), the most powerful being a supercharged 287 kW (390 bhp SAE) petrol V8. Supercharged V8 engine The mighty supercharged, 4.2-litre V8 is the flagship engine. Derived from the normally aspirated V8 engine also available in the Range Rover Sport, the supercharged version has 30 percent more power and 29 percent more torque. Yet it has the same compact package and similar fuel economy. Acceleration time from 0-100 km/h is 7.6 seconds; from 0-60 mph, 7.2 seconds (figures subject to final confirmation). The Range Rover Sport's V8 supercharged engine is not only more compact than a V10 or a V12, it has less friction and less complexity. As the supercharger is permanently employed to boost intake charge, the extra performance is present across the entire rev range - unlike an exhaust gas-driven turbocharger. The Eaton supercharger is positioned on top of the engine, in place of the normally aspirated induction system. Driven by a dedicated belt, the supercharger has two meshing impellers that ram air through twin intercoolers - to optimise air density - into the combustion chambers. The intercoolers have their own cooling radiators and there is also an additional air blast oil cooler. The camshaft profile is revised to allow the valves more movement to provide for the larger gas flow, while the fuel injectors have been calibrated to suit the high flow demand of the supercharged engine. The engine capacity is reduced (from the 4.4-litre normally aspirated) by the use of cast iron cylinder liners that take down the bore from 88.0 mm (3.46 inches) to 86.0 mm (3.38 inches). This strengthens the block by increasing the web thickness between the cylinders. Stroke remains the same at 90.3 mm (3.56 inches). The pistons have a revised bowl profile to suit the characteristics of the supercharged engine. The result is a capacity of 4.2 litres, maximum power of 287 kW (390 bhp SAE) at 5750 rpm and a massive 550 Nm (410 lb ft) of torque. This engine helps make the Range Rover Sport the fastest vehicle Land Rover has ever built. Normally aspirated V8 engine The quad-cam (two overhead camshafts per cylinder bank) engine delivers 220 kW (300 bhp SAE) at 5500 rpm and 425 Nm (315 lb ft) of torque at 4000 rpm. The camshafts are chain driven, while the chains and sprockets are of a fine pitch 'silent design' using inverted teeth, offering improved refinement over conventional chain drive. The camshafts operate four valves per cylinder, for optimal breathing and efficiency. One of the world's lightest V8 engines, it has a cylinder block and heads made from aluminium, while alloys are used in many other components to save weight. The engine uses Variable Camshaft Phasing (VCP), which automatically and continuously controls valve timing depending on driving behaviour and outside temperature. It is controlled by an electronic throttle, which allows throttle 'mapping' to change depending on driving conditions and provides an interface to the vehicle's Terrain Response system. There is also a 'limp home' facility, in the event of a system failure - crucial for a vehicle that may be used in remote areas. Like the supercharged unit, the normally aspirated V8 is made in a state-of-the-art engine plant in Bridgend, Wales. Compared with the Jaguar equivalents, the Land Rover engines have been further developed, particularly to increase their capability off-road. Like all Land Rovers, the Range Rover Sport must be able to tackle mountains and wade rivers, as well as cruise boulevards and motorways. The aluminium sump has been designed to ensure lubricant delivery at the extreme angles likely in off-roading and oil capacity has been increased by 18 percent. The oil pump has been redesigned and oil sealing has been improved for wading. Engine ancillaries have been positioned as high as possible to avoid damage from rocks and ruts and other off-roading hazards. Turbodiesel V6 engine In the Range Rover Sport, the turbodiesel engine develops 140 kW (190 bhp) at 4000 rpm and produces 440 Nm (325 lb ft) of torque. Maximum torque is developed at only 1900 rpm for excellent drivability and off-road capability. The engine runs with a compression ratio of 17.3:1, relatively low for a diesel. This reduces heat build-up in the piston bowl, further improving fuel-burning efficiency, reducing fuel consumption and emissions. The low compression ratio also reduces engine noise. The engine is fitted with a single 51 mm (2.0 inches) diameter KKK turbocharger with an electronically controlled Variable Nozzle Turbine (VNT). The equivalent Jaguar engine uses twin turbochargers, but the choice of a single turbo provides the Land Rover unit with increased torque and improves transient response. The turbocharger is fully sealed to suit Land Rover wading requirements. The VNT optimises charged air delivery at all engine speeds by altering the angle of the turbine vanes. This effectively widens the turbine inlet at low speed to improve torque and narrows it at higher engine speeds for better power response. The engine block is made from Compacted Graphite Iron (CGI), the first use of this material in volume engine production. It combines strength, stiffness, light weight and durability, allowing this engine to be physically smaller than most rival V6s. The inherent stiffness of CGI also improves durability and noise suppression. The strength allows the cylinders to be bored directly into the block casting, which removes the need for cylinder liners, saving weight. The crankshaft is carried in four main bearings, each cross-bolted with six bolts to provide a solid mounting and control vibrations. In its Land Rover application, the crank is further supported by an aluminium ladder frame attached to the bottom of the crankcase. A steel sump is attached to the ladder frame. The oil pick-up point is designed so that the vehicle can operate safely at extreme off-road angles, and baffle plates prevent oil surge and foaming. The cylinder heads are pressure die-cast in high-strength aluminium alloy. Each head carries twin camshafts operating four valves per cylinder. This 24-valve layout optimises engine breathing to improve economy and reduce emissions through better combustion. The camshafts are driven by a toothed belt, coated in PTFE to reduce friction. For reliability and durability, the belt is dedicated to drive only the camshafts. The inlet manifold is made from lightweight composites and is moulded integrally with the cam covers. It is isolated from the cylinder heads by an elastomeric material that reduces vibration, improving refinement. The engine is equipped with a glow plug in each cylinder to assist in cold starts, while the exhaust oxidation catalysts are positioned as close to the engine as possible to ensure a rapid warm-up. 'Intelligent Shift' automatic transmission For the Range Rover Sport, the Command Shift feature has been developed to give a more sporty 'feel' to the change and the response time of the compact gear lever is also more immediate than on other Land Rovers. There is also a Sport transmission mode, which - in an industry first - allows the throttle to 'blip' during auto downshifts under heavy braking. This helps engine braking and ensures that the vehicle is in the optimum gear when leaving the bend. In the Sport mode, the engine holds lower gears for longer. When cornering loads are detected, upshifts are also delayed - to allow the driver to have more 'feel' during cornering. Torque disturbances caused by gear changes are avoided. The fully adaptive 'intelligent shift' transmission alters its settings depending on the driving style and conditions. Aggressive driving means upshifting will be delayed, to allow for higher revs and more power. A more gentle driving style means upshifts will be delivered sooner, allowing for a more relaxed driving experience. The 'intelligent shift' facility works in both normal and Sport modes. The gearbox casing is unique to Land Rover, being especially stiff. The strong plastic-moulded sump has also been designed specifically for Land Rover, and offers superior off-road protection. The gearbox electronic control unit, made by Bosch, is housed within the sump for superior shielding. It communicates, by a high-speed link, with the vehicle's other systems, including Terrain Response. Twin-speed transfer box and electronic differentials The Range Rover Sport has a twin-speed transfer box with both high (for normal conditions) and low (for off-road) ranges. The shift is electric and can be made on the move. It is unusual for a sporting SUV to offer this low-range facility, which enormously improves traction over difficult or steep terrain. The centre differential is fully active. This 'e-diff' biases drive between the front and rear axles (in normal conditions it is distributed 50:50) and automatically varies torque depending on conditions. It can also be locked, to help traction in extreme off-roading. This is also performed automatically. An ECU controls an electric motor that locks the centre diff using a multi-plate clutch. An electronically controlled locking rear 'e-diff' is available. It is also controlled by the centre differential ECU. The differentials are mounted directly onto the chassis, to maximise ground clearance, giving improved off-road ability.
DRIVING DYNAMICS "The goal - as with all Land Rovers - was the broadest breadth of capability in the class," says chief programme engineer Stuart Frith. "But we had to shift the centre of capability towards sporty driving. That is the key ability of this vehicle. Yet we did not want to sacrifice ride comfort and refinement. And we also wanted to retain excellent off-road ability." The Range Rover Sport has been tuned primarily for on-road performance. Priorities were agility, roadholding, handling, excellent braking performance and tremendous driver appeal. Development testing included high-speed laps of Germany's notorious Nürburgring race circuit. Air spring suspension Sports car-like monotube dampers improve wheel control at high speed, and give the vehicle a more stable planted-to-the-road feel. Dynamic Response An engine-driven pump powers hydraulic motors that act on the anti-roll bars to alter their stiffness in response to vehicle cornering forces. Computers measure steering angle and horizontal acceleration and determine the moment at which the vehicle will lean. Dynamic Response then operates the hydraulic motors the instant the vehicle starts to roll. Its actions are imperceptible to the driver, but boost the sporting character of the vehicle. The Dynamic Response system on the Range Rover Sport allows for a much more supple ride on road, and helps give the vehicle much more 'feel' and handling suppleness, especially over undulating or slightly uneven roads. It allows for both excellent roadholding and the suspension suppleness which delivers great feedback. But on rough surfaces and off-road, assistance is automatically reduced and allows maximum wheel cross-articulation in extreme conditions. Speed-sensitive steering "The Range Rover Sport has very linear steering, to help the driver feel in absolute control of the vehicle," says Land Rover's chief engineer, vehicle integrity, Mike Cross. "The speed-sensitive power assistance allows for impressive agility at low speed and for superb stability at high speed." The steering rack is mounted ahead of the front axle, further to improve the vehicle's steering response. It is also mounted low to preserve the crash performance of the front end and is protected by a substantial cross member. Adaptive Cruise Control Sports tourer "We wanted the vehicle to have the best overall behaviour on-road, with an outstanding blend of comfort, refinement, agility and precision," says Mike Cross. "So it is equally at home on smooth winding roads, over long motorway distances and on smaller roads that have bumps and undulations. "Many of its rivals are not relaxing to drive on poor road surfaces. The Range Rover Sport is developed to be less frenetic and more relaxing. We believe it has a superior ride, is quieter, has a more comfortable cabin, and is a true sports tourer that can cover great distances effortlessly and swiftly." Any terrain "We build vehicles that can perform on almost any terrain," says managing director Matthew Taylor. "We fundamentally believe that your enjoyment should not stop just because the road does. Most rival sports SUVs can only cope with soft off-roading. The Range Rover Sport is an impressive road vehicle that can also cope superbly in the rough." The vehicle's Integrated Body-frame structure, as also used on the new Discovery 3/LR3, is enormously strong and offers superb protection for vulnerable electrical and hydraulic systems, as well as major mechanical components. The transmission includes a two-speed transfer box, with low range electronically selectable on the move. The air sprung suspension is height adjustable, allowing the whole body to be lifted clear of ruts, rocks and rivers, and any other impediments to smooth off-road progress. The result is far more ground clearance, off-road, than any sports SUV rival. The Dynamic Response active anti-roll system is automatically deactivated once the vehicle goes off-road, improving wheel articulation. This allows for full and free movement of the suspension, as if no anti-roll bars were fitted. When a side-slope is detected off-road, though, the hydraulic motors used in Dynamic Response lock the anti-roll bars, minimising vehicle lean to allow for a secure traverse. Wheels & tyres All road wheels are cast in aluminium alloy and are designed to withstand damage from kerbing and from off-road obstacles. Aluminium alloy wheels also help to disperse the heat generated during braking, reducing brake fade. The wheels have been specified to accommodate the large brake discs (wheel specification may vary by market). The entry-level wheel is 17 inches in diameter and seven inches wide, while the standard wheel is 18 inches in diameter and eight inches wide. A premium wheel is available on certain models, and is of 19-inch diameter and eight-inch width. Vehicles fitted with the V8 supercharged engine have 20-inch wheels. All wheels have a 'J' type profile to maximise tyre retention in the event of deflation. The spare wheel is carried on a frame located under the vehicle, between the side members, and is lowered using a winch arrangement. The mounting and the wheel itself contribute to the rear end crash performance of the vehicle. Large Brakes There are two different brake sizes offered. The supercharged and normally aspirated V8 models get 337 mm x 30 mm front discs and 350 mm x 20 mm rear discs. The diesel model gets 317 mm x 30 mm front discs and 325 mm x 20 mm rear discs. Normally aspirated and diesel models get twin-piston sliding callipers on the front brakes and single-pot callipers on the rear. The latest generation four-channel Bosch ABS anti-lock brakes are standard on the Range Rover Sport. This system also provides sensing and power for other dynamic control systems fitted to the vehicle, including Hill Descent Control (HDC), Electronic Traction Control (ETC) and Dynamic Stability Control (DSC). The system incorporates Electronic Brakeforce Distribution (EBD) to provide optimum braking regardless of the load state of the vehicle. Emergency Brake Assist (EBA) provides additional pressure to the braking system if a sudden application of full braking is sensed. The Range Rover Sport is fitted with an Electronic Park Brake. Application of the park brake is by a console-mounted switch. It is disengaged automatically when driving off. This device frees up the valuable space in the centre console area that would otherwise be taken by a conventional hand brake mechanism. The park brake acts on a 210 mm drum incorporated into the rear brake discs. Terrain Response 1. General driving (for normal on- and off-road conditions) Terrain Response uses a high-speed network of electrical architecture to control the relevant vehicle features, systems and technologies including: Engine management system: The throttle map is altered, improving drivability by matching torque delivery to the chosen terrain Electronic control system: Of the automatic gearbox to optimise gear change points Air suspension ride height: When low range has been selected, the air suspension automatically raises to off-road height whenever Terrain Response is switched from 'general driving' to any of the other settings Dynamic Stability Control (DSC): Normally stops torque to a wheel after loss of traction, but in some off-road situations torque feed is still desirable, even when traction is being lost. Terrain Response automatically adjusts the DSC, so appropriate torque is maintained Electronic Traction Control & Anti-lock Brakes: These slip and braking control systems are adjusted and tuned by Terrain Response to offer optimum grip, braking power and safety on the chosen terrain Hill Descent Control (HDC): This Queen's Award-winning Land Rover technology automatically restricts speed downhill, using the anti-lock brakes, and enables drivers to remain in control even on the most slippery of downhill stretches. HDC is automatically engaged on appropriate Terrain Response programs, and downhill speed rates vary depending on which surface is selected (in 'rock crawl' the lowest speed is selected to prevent vehicle damage) Electronically controlled centre & rear differentials: With different slip or locking rates for the different terrains Terrain Response works continuously. It made its production debut in 2004, on the new Discovery 3/LR3. Says chief programme engineer Stuart Frith: "Terrain Response is like having an expert beside you, telling you what gear and what settings you should be in. It makes off-road driving easier, in particular, and allows you to get the best out of the vehicle continuously, irrespective of the conditions."
BODY Integrated Body-frame The ingenuity of the Integrated Body-frame structure lies in its advanced computer-aided design, its trend-setting hydroforming production process and the use of advanced high-strength steels. Hydroforming uses fluid pressures rather than conventional tooling to form shapes. It allows for a much greater range of shapes and sizes and tighter tolerances, increasing precision and reducing weight. "The Integrated Body-frame is a superb starting point for the suspension systems of the Range Rover Sport," says chief programme engineer Stuart Frith. "It is a strong, immensely rigid structure, tapered at the front and rear for superior styling and aerodynamics. It is at its widest in the centre, for maximum strength in the central passenger area." The structure has most of its weight sited low, to give a low centre of gravity for good handling. In addition to its extra strength, compared with a monocoque, another advantage of the Integrated Body-frame is that vulnerable systems, cables and pipes can be packaged within the structure, offering great protection during off-roading. To provide the smooth but sporty feel that characterises the vehicle, special 'mini dampers' have been employed between the frame and body. The dampers are fitted adjacent to the body mounting rubbers and together form a 'mini suspension system'. They further improve ride comfort and reduce noise, vibration and harshness (NVH), while also improving driver feedback. Additional vibration dampers are also fitted to the chassis, to refine the vehicle's comfort further. Steel and aluminium panels The bonnet and tailgate continue Land Rover's long history of using aluminium for large panels. This saves overall vehicle weight and helps ease opening and shutting. Lightweight magnesium alloy is used in the front structure and forms part of the front crash crumple zone. The Range Rover Sport has a single-piece lifting tailgate, unlike the two-piece tailgates of the Range Rover and new Discovery 3/LR3. This one-piece design allows for a more rounded and aerodynamic vehicle shape. However, the glass area within the tailgate lifts separately, to allow easy boot access, especially in tight-fitting spots. All the steel panels vulnerable to corrosion are zinc-coated and all the alloy structures - of which Land Rover has more than 50 years' experience - are treated to prevent electrolytic interaction with adjoining steel components. SAFETY As well as offering good active safety - owing to its host of electronic stability controls, powerful brakes and class-leading traction - the Range Rover Sport also has exceptional passive safety. The Integrated Body-frame combines strength and rigidity. It improves vehicle safety, by providing occupants with an enormously strong structure to protect against collision damage. The hydroformed side members give exceptional side impact protection, and work in conjunction with side-impact bars and airbags. The frame structure is at its widest in the passenger area, to shield occupants and vital parts of the vehicle, such as the fuel tank. Buckle points control its collapse in an accident, as it crumples, taking energy away from the occupants. In addition, the front of the Integrated Body-frame has its collision 'load path' as low as possible. This is designed to reduce damage to smaller vehicles in the event of an accident, by impacting where the other vehicle's safety systems typically work most efficiently. The Range Rover Sport has also been designed with a lower bumper line, to match conventional cars. Airbags The side-impact protection system has a combination of seat-mounted airbags for the front seat occupants and side curtain airbags running the length of the passenger compartment. The curtain airbags deploy downwards to provide head protection for passengers during severe side impacts. An automatic protection sequence takes place in the event of a crash. This includes instant shut-down of the engine and fuel system and operation of the hazard warning system to warn other road users. All the interior lights are activated and all doors are automatically unlocked. |

INTERIOR Seats Both front seats have power adjustment as standard with the driver's seat having an eight-way power system - the switches are located in the seat valances. A memory function is available. Both front and rear seating positions are equipped with two-level cushion heating. Both front seats have manually adjustable head restraints, which house the twin LCD screens for the DVD system (where fitted). With the roof-line profile tapering towards the rear, the rear headlining is deeply profiled around the sunroof cassette to give maximum headroom to the rear seat passengers. The interior design is complemented by a choice of high quality trim fabrics in four interior colour ways. The seats are offered with a premium cloth as standard and a high-grade leather option. Vehicles fitted with the V8 supercharged engine have a unique and distinctive 'sparkle' leather trim as standard. A premium leather trim which features a softer leather in a ruched style is also available. The rear seat splits asymmetrically and 'flips and folds' to provide maximum space in the rear load area. The boot is one of the biggest in the class, and provides plenty of space for sporting equipment - including golf clubs - and also sufficient room for bicycles and ski gear. The instrumentation is clear and well displayed. Circular analogue gauges have metallic bezels and are grouped neatly in the main binnacle, directly in front of the driver. The large centre console is high and comparatively close to the driver. The short, sporty gear lever is angled to the driver. The other side of the console is given over to storage and cup holders that are capable of taking the largest 'big gulp' beverage containers. The vehicle's use of an electronic parking brake means that the console area is unencumbered by a manual handbrake lever and its linkage. The facia design accentuates vertical and horizontal lines. This very geometric composition is typical of Land Rover's interior design philosophy, as seen on other recent vehicles. On the Range Rover Sport, however, the instrumentation and major switches are closer, and the driver is more enveloped by the controls. The driver sits high, and enjoys the Command driving position characteristic of Land Rovers. Visibility is excellent - fore, aft and sideways. It is easy to see over parked cars, traffic and hedges, as well as over spray on wet roads. All four corners of the vehicle are visible for easier parking and manoeuvring. The big glass area provides a superb panorama. Craftsmanship and quality are key features of the new Range Rover Sport's cockpit. Apart from the premium cloth and leathers used for the seating upholstery and the luxurious cut-pile carpeting, wood and metallic finishes are also widely used. The switchgear, which is unique to Land Rover, has a chunkiness and precise movement that is typical of a quality vehicle. Controls that are used regularly, such as facia vents and major switchgear, have a rubberised finish to improve tactility. All grab handles are damped. The facia is supported on a die-cast magnesium alloy cross beam that is both light and strong. It provides excellent support, reducing the likelihood of any movement, squeaking or rattling. The facia moulding is in Thermoplastic Urethane (TPU) which has a soft, premium feel, resists fade caused by sunlight, and has minimal plasticizers, reducing the 'mist' deposited on the inside of the screen. Roof trim and door pillar trim are soft fabric. Two roof-mounted consoles provide interior lighting. Low-level 'waterfall' lighting is incorporated into the front dome lamp, and is activated when the headlamps are turned on. Automatic air conditioning is standard, and includes a particulate filter to remove pollutants in both fresh air and recirculating modes. The temperature is selected using facia-mounted controls. There are separate controls for the driver and front seat passenger, and both sides operate independently. For the rear seat passengers, there are two vents at the back of the centre console. The Range Rover Sport has a comprehensive in-car entertainment and information system, including the availability of a twin-screen DVD system. Other features include a harman/kardon 'Logic 7' digital surround-sound in-car hi-fi, a comprehensive navigation system including on- and off-road modes and an integrated telephone. The different elements of the 'infotainment' system are connected by a fibre-optic MOST network for rapid data transfer. The top-of-the-range sound system has been developed by harman/kardon using advanced 'Logic 7' technology. This system uses 14 speakers and is powered by a 12-channel digitally controlled amplifier. Each channel produces 50 watts to create a 'surround-sound' stage within the vehicle. |
||||
The head unit is integrated into the facia and can store up to six CDs in its integral stack, as well as receiving a variety of broadcast wavelengths. It can also play MP3 files recorded on CDs, giving a capacity equivalent to 66 albums. A centre fill speaker is positioned in the middle of the facia 'topper panel'. Each front door is fitted with a bass unit, mid-range speaker and a tweeter. The rear doors each have a metal matrix bass unit and a tweeter. An 11-inch sub woofer is integrated into the tailgate and two surround-sound speakers are fitted into the rear headlining. The mid-range hi-fi system features nine speakers and a six-stack CD player. A single CD system is also available which uses an internal amplifier powering eight speakers. |
||||
A rear twin-screen DVD system is available, with two 165 mm (6.5 inch) high-resolution LCD screens fitted in the rear of the front seat head restraints and a six DVD changer mounted in the boot area. The video output can be streamed into the front facia-mounted 180 mm (7-inch) LCD screen when the vehicle is stationary. The soundtrack can be played through the 'Logic 7' system to give a full surround-sound cinema experience. Games stations and MP3 units can also be connected to the system. A state-of-the-art satellite DVD navigation system is available, which includes the latest generation of off-road navigation. Jam-busting Traffic Message Channel (TMC) systems, where available, broadcast on a specific radio channel to warn of hold-ups. The satellite navigation system can suggest an alternative route. The navigation system is controlled via the high-resolution, easy-to-read-in-any-light front screen, which is touch-activated. Two buttons switch the screen between the main 'Home' menu and the navigation system. The screen also displays information from the Terrain Response system. Voice recognition is available for navigation and audio controls. The Range Rover Sport offers an integrated mobile phone that employs a system developed by Nokia. This installation incorporates the Bluetooth system for remote operation although non-Bluetooth phones can be fitted into the cradle for recharging. The phone cradle is mounted in the cubby box lid and will accept most popular models of mobile phones, including 'flip phones'. Bluetooth-enabled phones will function even if not inserted in the cradle. The phone is integrated into the vehicle's audio system and has a microphone mounted in the roof console. Incoming speech is relayed through the audio system, which mutes the normal programme when a call is received or placed. TESTING Though expected to spend much of its life on-road, the Range Rover Sport still had to undergo Land Rover's arduous on-road and off-road test programme - probably the most varied and toughest in the automotive industry, covering over four million test and development miles in all. Challenges varied from the Nürburgring race circuit and the Nardo high-speed test track in southern Italy, to the bone-jarring tracks of the Nullarbor Plains in Australia's inhospitable outback. The Range Rover Sport has also powered along German autobahns, rushed up sand dunes and ploughed through the thick mud of Eastnor Castle, on the England/Wales border. Extreme hot weather testing was done in Dubai and Death Valley, as well as Australia and South Africa - in heavy town traffic as well as in the wilds. And to experience temperatures a full 80 degrees cooler, the Range Rover Sport ventured to Canada and Sweden. The vehicle's performance on ice and snow was also fine-tuned here. Despite its on-road emphasis, the Range Rover Sport had to meet all Land Rover's usual off-road testing criteria - the toughest in the automotive industry. It has to be able to wade in water 700 mm deep on excursions. Climb and descend 45 deg gradients. Remain stable when driving across a 35 deg slope. The handbrake must hold the vehicle on a 45 deg slope (harder than the industry average). And the vehicle must operate in temperatures as extreme as minus-40 deg C to plus-50 deg C.
