Making its debut at the Geneva Motor Show 2011 - Jaguar XKR-S is even more extreme expression of Jaguar's passion for building beautiful, fast cars. For the first time a production car, Jaguar has access to the exclusive club '300kph thanks to the effortless performance of the engine compressor AJ-V8 5.0-liter. A revised map supply: direct injection engine now produces 550P and 680nm of torque. extensive recalibration have ensured that supply and service is seamless, which contributes to a time of 0-60 mph in 4.2 seconds. Performance exhaust assets encourages and rewards the enthusiastic driver with audible feedback spectacular race of inspiration.
Performance Jaguar XKR-S is reflected in both the interior and exterior design, which feature a new paint colors that reflect the unique heritage of Jaguar Racing. As competition in the past, Jaguar XKR-S look to respect the principle of form following function. In addition, design changes and so that it reaches 300kph, XKR-S has been the subject of extensive development Computational Fluid Dynamics. Resulting from changes to reduce the front and rear, and optimized over a quarter of the lateral aerodynamic stability.
Performance Jaguar XKR-S is clear from the moment the taxi driver will allow a new seat cuddle performance near the shoulder blades significant support in difficult angles. Seats with 16-way adjustment, memory and work of heating at the same time a new three-spoke steering wheel provides a comprehensive interface to the car and driver.
Style
Ian Callum, Design Director of Jaguar Cars' design, this machine is not image, was found to be true. Like other iconic Jaguar before its design is driven by geometry and aerodynamics of a purity of design itself. 300kph is necessary to achieve the physical appearance, it seems that if you do not like, you probably do not like the way you drive, either. "
The first Jaguar exclusively under the direction of Design Director Ian Callum has received awards XK world for its elegant appearance. Now style changes with other XKR-S at the forefront of modern sports car design. Refined, LED headlights, more compact air intakes on the sides and main vertical mechanical ventilation all contribute to a more targeted before the end. At the rear of the car on "the famous Jaguar Leaper now takes a prominent place in the middle of the trunk.
Jaguar XKR-S also calls for an aerodynamic change to reach a top speed of 300kph quite as planned, and Jaguar and is designed exclusively for the clean lines and quirky eye view. Since the XKR-S has a top speed approaching a condition that must be channeled neatly over the air, around and under the car to maintain stability and a balanced front and rear downforce. The reduction of 26 percent of design have been achieved.
The revisions were needed after considerable computational fluid dynamics work, demonstrated through wind tunnel tests and are exclusive to this flagship of the XK range. The most dramatic changes have been applied to the front of the car, to radically alter their appearance and give a firmer appearance. A new bumper features vertical lines near the flow function on the edges of the oval opening and support the new carbon fiber splitter and spoiler below. In the end edges of the front fenders, vertical air channel slots on the sides of the car and along the larger thresholds to increase directional stability at high speeds.
To balance the front and rear elevation, the Jaguar XKR-S is equipped with a rear wing for the first time in the XK range. This also has its center section in carbon fiber, is working with similar structure built in rear bumper Venturi.
The emergence of new Jaguar XKR-S said is subtly highlighted by some carefully chosen details of this exclusive model. Exterior trim has a glossy black finish, complemented by 20-inch forged alloy lightweight Vulcan in a black finish techniques.
The XKR-S is available in a choice of five colors of paint, two of which evoke the heritage of Jaguar's competition: Italian and French Racing Blue Racing Red.
As the lining of a suit, the final touch is provided by the brake calipers, available in red or metallic silver and bearing the name "Jaguar."
Performance / Powertrain
Russ Varney, Chief Programme Engineer, XK: "The XKR-S, we exploited the inherent capabilities of the architecture of aluminum to create a show completely derivative being able to develop all the characteristics of the vehicle and offers an irresistible" smile satisfaction "of driver action.
Surprisingly, the engines have always been a strong heart beat of the street racing cars from Jaguar and records were straight-six V12 XK120 smooth, which made it the fastest four-door XJ12 in the world when it was launched.
The AJ-V8 has joined the illustrious list when the first was shot in life, but the Jaguar XKR-S, which is presented in its most potent to date. Now in its third generation and with the addition of turbocharging, all-aluminum four camshafts engine not only offers superior performance, but also with considerable efficiency technologies are integrated, including direct injection guided by a jet ( RIMS) and two calibration of the independent variables (DIVCT).
The fuel is delivered directly to the center of the combustion chambers at a pressure up to 150bar in the middle six-hole mounting injection system guided by an aircraft in order to maximize the air-fuel mixture and improve responsiveness, especially low speeds. It also allowed an increase in compression ratio of 9.1:1 to 9.5:1 to improve fuel economy and reduce multiple injections of the heating phase to increase the efficiency of the catalyst and reduce emissions.
The whole system has four camshafts time variable instead of being controlled by oil pressure, are activated by positive and negative torque generated by the movement in and out, allowing more smaller oil pump installation more efficient, reducing fuel consumption. VCT units respond to three times faster than before with activation rates of more than 150 degrees per second at any point in the range of speeds, making it the best engine Jaguar has built, without gaps in the implementation of power.
As the car itself, the AJ-V8 architecture with the characteristics of aluminum high pressure cast iron block reinforced lightweight shirts and cons of cast iron-bolted main bearing caps, which contributes to the sophistication to match his power. The four-valve cylinder heads are now constructed from recycled aluminum to reduce the environmental impact of manufacturing the engine.
Located in the "V" of the cylinders are the Roots type supercharger with double Jacuzzi and two interchanges to help give the XKR-S with a burst of such emergency. This sixth generation unit forced induction is 20 percent more thermodynamically efficient than its predecessor, while the intercoolers have their own cooling water to reduce the temperature of compressed air to optimize the power and efficiency.
The exertion of power produced by the system meant it was relatively easy to release adds 40PS and 55nm more than the standard XKR. Remapping of the fuel properties and increase the exhaust flow through an active exhaust system has brought the total 5.0-liter V8 is now 550PS and 680Nm, making it the most effective engine Jaguar has ever done, and the Jaguar XKR S-hit 60 mph in 4.2 seconds and breaches the magical 300kph barrier easily.
Performance active exhaust system to give such a spirited performance also manufactures a soundtrack exciting motorsport-inspired sound to reward the enthusiast driver.
Handling
Mike Cross, chief engineer, vehicle integrity, "This includes a show car Jaguar should be as capable, accurate and moving on a wet Welsh B-road as it is in Nurburgring The duration of response has been reduced at least to give. connected to the car feel more in the way it runs, runs, stops and goes. "
Jaguar pioneered the use of aluminum in building production cars that use low and high mass metal tensile strength to maximize the benefits in terms of performance, agility, fuel consumption and emissions.
The platform behind the XK range makes the car lighter and more rigid in its class with an empty weight 1,753 kg and torsional stiffness of 28,400 newtons per degree. This fundamental force has integrity Jaguar vehicle team, led by Mike Cross, to develop the dynamic qualities of the Jaguar XKR-S as possible without compromising refinement. Each Jaguar achieved incomparable blend of sports appeal and luxurious comfort and the XKR-S is the best driver never worn Jaguar.
During the foundation of the architecture of aluminum as a starting point, both front and rear suspension are upgraded. The double wishbone front suspension was revised with a steering knuckle new aluminum, which increase the stiffness and camber of the wheel of 0.13 degrees per Kilo Newton transform accuracy and weight management levels higher connection, feedback and precision. Active Differential Control is reprogrammed to reduce the control sensitivity at high speed the car is capable, enhanced stability and driver control.
rear suspension geometry has been revised with rear wheel steer optimized for maximum flexibility, while the spring rates have increased at both ends of the car by 28 percent. custom software for Jaguar adaptive damping that was written for the Jaguar XKR-S, which provides both control of his body and maximum traction and grip.
wheel sizes have increased with the only light forged wheels Vulcan 20-inch alloy now have a width of nine inches front and 10.5 inch rear for greater precision and grip. The new wheels wear Pirelli P Zero 255/35 R20 before measurement, 295/35 R20 at the rear. This combination reduces the unsprung mass of 4.8 kg with a corresponding improvement in the dynamic treatment.
Dynamic Stability Control System has been modified to maximize the benefits of wider tires. Trac DSC mode using special traction, stability and options for changing thresholds EDIF slip differential torque distribution and levels of intervention to allow the experienced driver to explore the outer edges of the envelope of performance and handling .
The XKR-S is fitted with a Jaguar high performance brake system. Lighter and more powerful, this feature cast aluminum calipers piece of iron and partly to a combination of power, stability and ease of use. Disc brakes - measuring 380mm front and 376mm at the rear - are broken down to provide the braking power of repeated resistance. In combination with the buffer area greater than 44 percent against and 31 percent behind the system offers a total security and confidence in road and track. The stopping distance of 124 mph improved 2.7 percent during the XKR is already impressive.
The end result is a car that captures the essential duality that is characteristic of all great Jaguar, capable of carrying the driver to the legendary Nürburgring circuit in the comfort and silence silent, but still able to provide a sub-eight minute lap and then go home with ease.
Within
Cottage any Jaguar has always been a unique, special place to spend time and XKR-S meets all the expectations from the moment the driver will be greeted by the Start button, red like a heartbeat. When pressed, the engine starts, the deep resonance and Jaguar Drive Selector rises in the center console, as the first contact to start the bonding process of a machine man.
The interior of the Jaguar XKR-S has been subtly renovated with a lot of new packaging materials such as soft touch paint for shiny black ebony switches and center console. The model will be available exclusively with a line of dark aluminum finish as an option for the plate.
A new leather-wrapped, multifunction steering wheel steering was also added, providing a pleasant tactile interface between car and driver as well as the brilliant, Jaguar-embossed, stainless steel pedals.
Exclusive Jaguar XKR-S is the new front seats with integrated headrests performance and greater side support and backing to hold the driver and passenger in comfortably and securely in place during high speed corners that this car is capable. Set of 16 channels of chick pad, lumbar and strengthen the elements are complemented with memory functions and heating.
Feeling when you are offered during the execution of Jaguar XKR-S has a higher carbon skin a special place where a unique contrast of the micro-tubes and combinations of Reims blue stitching, red and ivory. combination of two shades of gray and Tan and gray and red are available.
Jaguar XKR-S is not only the fastest Jaguar ever, but even the most agile, responsive and focused on the driver. Pinnacle XK range is based on feedback from the supercharged XKR, and has been developed to extend the performance parameters of the car. This new kind of harder cutting enthusiastic driver allows to study the dynamics of the external borders of the car, without losing the sophistication and usability, which Jaguar is renowned. The structural integrity of a lightweight aluminum frame can be reworked suspension with components tailored to increase the stiffness without loss of the right or the refinement of Jaguar's legendary ride comfort. Custom aluminum front suspension and revised in silence behind the geometry of the Allies are stiffer springs and shock absorbers, forged alloy wheels and steering calibration seeks to minimize the delay of response and produces a more connected and agility .
