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.
The performance target for the Jaguar XKR-S is evident from the moment the driver enters the cabin with back seats pamper performance wings from the shoulders forward in support around the curves. The role of 16-way seat adjustment, memory function and heating, while a new three-spoke steering wheel provides the perfect interface between car and driver.
Design
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. "
Jaguar designed the first entirely under design director Ian Callum the XK has won awards around the world for its elegant appearance. Now, some style changes to keep the XKR-S at the forefront of modern sports car. Thinner, LED headlights, the main air intake more compact and vertical side fan power contribute to a more settled before the end. In the rear of the car the "Leaper" famous Jaguar now sits in the center of the trunk.
Jaguar XKR-S also needs aerodynamic changes to reach its top speed of 300 km / h imperturbable manner expected of a Jaguar and was designed exclusively with an eye for clean lines and uniqueness of the object. As XKR-S is almost top speed, it is necessary to redirect air cleanly above, around and under the car to maintain stability and ensure the balance of front and rear support. An overall reduction in the lift of 26 percent is reached.
necessary corrections have been made after extensive work, Computational Fluid Dynamics demonstrated in wind tunnel tests, and are unique to this area of the flagship XK. The most dramatic change has been applied to the front of the car to radically alter the appearance and lending to the look of him. The new bumper features near vertical feature lines running down the edges of the oval-shaped air intake, and supporting new carbon fiber splitter and a rear lower spoiler. The extreme edges of the fore wings, the vertical output channel of air along the sides of the car, and along windowsills broader add high-speed directional stability.
In order to balance the front and rear axles, Jaguar XKR-S has a separate wing back, first in the XK range. This is in addition to its central section in carbon fiber, acting in concert, to structure Venturi built on the rear bumper.
Self-assured appearance of a new Jaguar XKR-S is subtly highlighted some carefully selected exclusively on the details of this model. The exterior is finished in glossy black, add 20-inch light alloy forged Volcano dark finish technique.
XKR-S is available in a variety of five colors of paint, two of which raises competition of the Jaguar heritage: Italian and French Racing Blue Racing Red.
As the mountain of tailor-made suit, finishing calipers offers, available in red or bronze and decorated with the name "Jaguar".
Performance / Powertrain
Russ Varney, Chief Program Engineer, XK: "With the XKR-S has exploited the inherent capabilities of the architecture of aluminum in its entirety to create a result of the extension to track the performance of all the attributes of cars and offer a convincing "smirk" the response of the pilot. "
Amazing engines have always been the heart that is pounding on the road and Jaguar racing cars of the record of six cylinders in the V12 XK120 without problems the XJ12 was the fastest four-doors in the world when 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 its power.
As the same car, AJ-V8 has an aluminum architecture, high-pressure die-cast block light and supplemented with iron rods and cross-bolted main bearing caps that contribute to its refinement. four-valve cylinder heads are now made of recycled aluminum to reduce the environmental impact of engine production.
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 glut of electricity produced by this system means it is a relatively simple matter to release an additional 40ps and 55nm over the standard XKR. Remapping the performance of the engine fuel system and increase exhaust flow through the use of an active exhaust system has raised the total production of 5.0-liter V8 is now 550P and 680nm, this which makes the engine of the road the most powerful Jaguar ever made, and allows Jaguar XKR-S to hit 60 mph in 4.2 seconds, and unlike the magical barrier 300 km / h with ease.
Active performance exhaust system that can provide spirited performance also produced an exciting soundtrack of motor sports as inspiration for the aural reward the enthusiast driver.
Handling
Mike Cross, chief engineer, vehicle integrity: "This vehicle includes everything a Jaguar should be the performance as a measure, accurate and exciting on a wet Welsh B-road as it is at Nurburgring Each response time is minimized to give a car. feel more connected to how he runs, runs, stops and goes. "
Jaguar pioneered the use of aluminum construction for production cars, the exploitation of low mass, metal, high tensile strength to maximize the benefits in terms of performance, speed, fuel consumption and emissions.
The platform supports a range XK is the car lighter and more rigid in its class with an empty weight of 1753 kg and the torsional stiffness of 28,400 Newton per degree. This fundamental force has integrity Jaguars vehicles team, led by Mike Cross, to develop the dynamic properties of the Jaguar XKR-S in its entirety, without affecting the refinement. Each Jaguar achieves unmatched blend of sports appeal and luxurious comfort and XKR-S is the most driver-focused Jaguar ever made.
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 steering optimized for maximum agility, while the springs have increased on both ends of the car by 28 percent. Jaguar customized software for adaptive damping was written for the Jaguar XKR-S, providing 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.
The dynamic stability control system has been modified to maximize the benefits of wider tires. Trac DSC mode, this is for special use of traction, stability and change settings ediff threshold shift, the differential torque distribution and levels of intervention to give the experienced driver to explore the outer edges of the envelope of performance and handling.
XKR-S is equipped with a high standard braking system with Jaguar. Lighter and more powerful, has some iron and aluminum calipers combination of power, stability and a feeling. brake discs - measuring 380 mm front and 376 mm rear - are ventilated to provide frequent, fade-free stopping power. Together with the pad area increase of 44 percent front and 31 percent of the rear system offers a complete security and confidence in both road and track. 124 mph distance termination was improved by 2.7 percent XKR already impressive.
The end result is a car that captures the essential duality that is characteristic of every great Jaguar, is capable of carrying the driver of the legendary Nurburgring in total comfort and silence modest, yet able to provide a sub-eight minutes lap and then return home with consummate 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.
Decorate Jaguar XKR-S is a subtly relaxes a number of new cutting materials, such as moves and feel soft ebony black glossy paint finish center console. The model is also available in aluminum linear dark background, because the possibility of wood veneers.
A new leather-wrapped steering wheel with multi-function was also added, giving a nice touch interface between car and driver, which makes the polished Jaguar-embossed, stainless steel pedals.
Exclusively for the Jaguar XKR-S is a new performance front seats with integrated headrests and side increased support and squab to keep driver and passengers safely and comfortably in place during high-speed corners the car is able. Adjusting to 16 channels of squab cushion, lumbar and reinforcing elements are complemented by functions of memory and heating.
The sense of the opportunity while running Jaguar XKR-S will be amplified by the new charcoal leather accents covering the seats, and offers exceptional contrast micro-tubes and combinations of stitches in Reims blue, red and ivory . Duotone combinations of charcoal and charcoal with Tan with Red is also available.
