Draft Range Stormer
The Range Rover Sport was created earlier by the Range Stormer concept car, introduced at the 2004 North American International Car Show. It is a superb, sporty short-wheeled, short-wheelbase 3-door coupe in historical context Land Rover. Designed by Richard Woolley, the first complete marque concept car features a split-folding gullwing door, one-piece skeleton chair, clamshell hood, 22-inch alloy, top speed of 289 km/h, 4WD and 2500Ã, kg weight. Range Rover Sport has a much more conservative design with five doors and a wheelbase that is barely shorter than the Range Rover Vogue. The Stormer replica was built by the Western Customs of Corona, CA for Sheikh Hamdan bin Mohammed Al Maktoum, Crown Prince of Dubai, on the occasion of opening the Dubai West Coast Customs; This car is currently listed under Traffic Traffic and the Dubai Highway.
The Range Stormer is now on display at the Heritage Motor Center in Gaydon, Warwickshire, England.

First generation (L320; 2004-2013)
Chassis
This chassis has been adapted from an integrated, semi-monocoque, integrated designframe that debuted on Discovery 3 in 2004. It allegedly provided the Range Rover Sport enhancement and the structural sturdiness of the monocoque chassis with the robustness of a separate chassis design for off-road applications. It also allows for the manufacture of cheaper vehicles due to the large number of common components. Despite sitting on a modified version of the Discovery 3 chassis, it is smaller than its more utilitarian brother in every dimension with a shorter wheelbase of 140 mm (5.5 inches). Its smaller dimensions and its uneven roofline make it impossible to accommodate third-row residents like Discovery 3, but as a sports sportsman, it was never meant to be a seven-seat. Brembo's front brakes are standard on all models except the TDV6.
Powertrain
The Range Rover Sport is powered by an all-aluminum Jaguar engine with a 4.2 liter All-AJ-V8 that produces 390 hp (290 kW) and 550 N? M (410 Â £ l). An aspirated 4.4-liter natural variant produces 300 hp (220 kW) and 425 N m (313 lb. Ft) and has been adapted by Land Rover with slightly larger capacity and increased torque. Both gasoline engines have been designed with a sump and oil pick-up system to allow operations at extreme angles. Due to lack of popularity, the naturally aspirated power plant was removed from the UK market in 2007. The 2.7-liter TDV6 turbodiesel is an adaptation of PSA/Ford development and generates 190 hp (140 kW) and 440 N? M (320Ã, lb? Ft) in a Land Rover disguise. It features solidified graphite iron blocks and aluminum cylinder heads with fast piezo switching crystal injectors. Debuting at Sport and Vogue in 2007 is a twin turbodiesel TDV8 3.6 liter. This machine is an advanced adaptation of TDV6 but has 90 degree degrees (as opposed to 60 Â ° layout), twin variable geometry turbochargers, and deactivation of inlet valves. All engine variants are mated to a six-speed automatic adaptive ZF transmission with CommandShift that reacts and adapts to different driving styles. CommandShift gives drivers the freedom to sequentially manipulate tooth changes.
Suspension
Air suspension, as standard, gives the driver the option of three vehicle height settings including standard 172 mm (6.8 inch) standard elevations, 227 mm (8.9 inch) off-road altitudes and reduced access modes. There are also extra heights available that are accessed by holding each key when the height of off-road ride is not enough. When the vehicle is out, its control system will feel the reduced weight on the air spring and the height of the mount is automatically raised to the largest suspicion articulation. The cross-link aspect of the suspension system, which debuted at the Range Rover L322 in 2002, resulted in better off-road performance by an electronic operating valve on a pneumatic line connecting an adjacent airspace. In the case of wheels on one side raised when traveling off-road, the pneumatic valve is opened and the adjacent wheel is forced down, simulating the live shaft setup action.
Medan Response
The Land Rover patented Land Response System that debuted on Discovery 3 was installed as standard on all models. The Medan response allows the driver to adjust the chassis and transmission settings to match the terrain. Five settings are available via the turn knob on the center console. This includes public driving; grass, gravel, snow; mud and ruts; sand; and crawling rocks. Suspension height elevation, engine management, throttle mapping, transfer case range, transmission settings, electronic driving aids (such as electronic traction control (ETC), dynamic stability control (DSC) and hill control (HDC)) and electronic e-diff all manipulated through the Medan Response system. All Range Rover Sports comes with a standard center e-diff from the Magna Steyr Powertrain which electronically locks and unlocks and divides torque through a multi-plate clutch package tool located inside a transfer box that also offers a 'shift-on-the-move' operation dual-range. A rear e-diff is optional on all Range Rover Sport models and is able to lock and unlock instantly. An in-dash view is available which, inter alia, is related to the Medan Response and displays important off-road information such as e-diffs status, steering angle and wheel articulation. It can also tell wheel drivers who have no contact with the ground.
Driving technology
Dynamic Response incorporates an active electro-hydraulic anti-roll bar that reacts to the cornering force and activates and disables it appropriately resulting in a noble on-road handling. Dynamic Response also helps off-road performance by separating the anti-sway bars to enable maximum wheel articulation. The system in the evolving ACE (Active Cornering Enhancement) system is available on the Discovery Series II but is described as proactive rather than reactive. Positive Torque, the system standard on all TDV8 and Supercharged models, electronically shrink throttle, resulting in faster downshifts and enormous availability of torque reserves. The speed-sensitive steering system, adopted from the Jaguar is standard on all models and there is an optional bi-xenon headlamp that acts with the steering angle to aid vision. Active Cruise Control (ACC) with Forward Alert system incorporates an integrated front bumper radar that detects vehicles running in front and adjusts vehicle speed to match. This system scans the road ten times in one second, has a field of view of 16 degrees and Land Rover claims to be able to distinguish between heavy vehicles and adjacent motorcycle lanes, which cover a distance of at least 180 meters (590 feet) in front. Four preset distances can be selected and will ensure Sport maintains the desired distance from the vehicle to be followed.
Security
The NCWR organization (Whiplash Ranking New Car) tested the Range Rover Sport in 2010 and gave it the following score:
G = Good, A = Acceptable, M = Marginal, P = Poor
Security
Range Rover Sport is tested by the New Thatcham New Vehicle Security Rating (NVSR) organization and achieves the following levels:
Facelift (2009)
Facelift model was first shown at the New York Auto Show in April 2009. Range Rover Sport 2010 featuring a more aerodynamic front-end including headlights, grille and a new bumper. Also new revised rear lights and rear bumper. The interior revision is more significant with new fascia, steering wheel, door coating, chairs, instruments, and switchgear. This new model has more skin buttons and almost 50 percent less dash button than previous models. Three new engines debuted at the 2010 Sport. These include the all-direct injection V8 gasoline engine, a new 5.0-liter all-aluminum alloy with a sucked and supercharged natural force as seen in Jaguar's latest high-performance line of vehicles. The naturally aspirated model produces 375 hp and 375 ft-lbs of torque while the supercharged produces 510 hp and 461 ft-lbs of torque. Also new is the highly revised 3.0-liter version of the current 2.7-liter TDV6 that produces 180 kW (240 PS, 240 hp) and 600 N (mb), adapted from the Jaguar AJ-V6D Gen III. This machine has a parallel sequential turbocharger - single variable geometric turbocharger and single fixed geometric turbocharger that is only active when needed as seen on Jaguar XF Diesel S. All new engines generate increased power and torque over its predecessors while delivering better fuel economy and reducing CO 2 emissions. Equipped with the sixth generation twin-vortex supercharger with improved thermodynamic efficiency of 16 percent, the new 5.0-liter supercharged engine generates 29 percent more power and torque 12 percent higher than the current 4.2 liter engine, but CO 2 emissions and fuel consumption increased by 5.6 percent and 6.2 percent, respectively. The new 3.0-liter TDV6 engine produces 29% more power and 36% more torque than the 2.7 liter engine, but CO 2 emissions and fuel consumption both increase by 9%. The 2010 model year Sport is also equipped with a new six-speed ZF HP28 automatic transmission. Designed to improve performance and efficiency, the new transmission involves grip lock-ups of any previous gear after selection. Completion of the suspension also occurs with the introduction of the world's first production damping system using model-based prediction technology that continues to optimize the new DampTronic Valve Technology dampening settings to optimize vehicle riding and control. Further improvements to the award-winning Medan Response system have been ongoing for 2010. Revisions to the rock crawling program reduce scrolling when crossing rock blocks that provide a quieter ride over a rocky terrain. The addition of a new 'sand rollover control' prevents wheels from digging when driving in fine sand thanks to the revision of the traction control system. The Hill Descent Control System has also been enhanced with the addition of Gradient Release Control, which inhibits the initial rate of acceleration as it descends on a steep slope.
Controversy
Range Rover Sport made the Ford Premier Automotive Group a target of protests by Greenpeace in 2005. Protesters infiltrated the assembly facility and temporarily suspended vehicle production. Greenpeace cites the issue of greenhouse gas emissions, and by extension, global warming. The US Environmental Protection Agency estimates that non-supercharged cars are 14 mpg -US (17Ã, L/100Ã, km; 17 mpg -imp ) (combined). Although for this test the EPA uses their newly calibrated system for 2008 and beyond. Greenpeace says they do not take issue with vehicle production like Land Rover Defender as they are typically used for off-road applications on a much more frequent basis than vehicles like the Range Rover Sport they claim to have "set especially for road performance". Second generation (L494; 2014-present)
The second-generation Range Rover Sport was announced on March 27, 2013 at the New York Auto Show. Some roads were closed in Manhattan for a launch party at the Auto Show starring James Bond actor Daniel Craig.
Design
The new Range Rover Sport continues in the direction of design that produces the Evoque styling, and the full size 2013 Range Rover. It is 4 inches (100 mm) longer, being 191 inches (4,851 mm) in length; and 400 pounds (180 kg) lighter, weighing in at 4,727 Â £ (2,144 kg). Unlike previous generations that use the integrated bodyframe chassis, the L494 Range Rover Sport uses an all-aluminum monocoque body, just like the L405 Range Rover.
This introduces a Dynamic Response suspension with an active anti-roll bar.
SVR (2015)
On August 11, 2014, Range Rover SVR (Special Vehicle Racing) was announced by Land Rover at Pebble Beach. Sport models of aesthetic changes and performance improvements.
The design of this model has a completely revised front bumper, with larger channels and the main grille finished in black. Front quarter channels are also revised and completed in black. The rear bumper is also completely revised with new, clearer diffuser and twin-circle exhaust tips. SVR comes with 21-inch alloy wheels, wrapped in all-season 275/45 R21 tires as standard.
Performance improvements for SVR include a 5.0L superlarged V8 dragged out of the Jaguar F-Type, with a power output of 550 HP and a torque output of 502 lb.ft. Transmission has been programmed to shift 50% faster and keep the torque converter locked once in second gear. The chassis has also been revised for the model. Debut Adaptive Dynamics with magnetorheological dampers. New to SVR is the addition of an active exhaust system with an electronically controlled valve. Improvements make the SVR capable of 0-60 mph in 4.5 seconds and a top speed of 162 mph, one of the fastest of its kind.
