2012 Jaguar XKR-S Review

Making its debut at the Geneva Motor Show 2011, the Jaguar XKR-S is the most extreme expression of the passion of Jaguar cars in building beautiful, fast. For the first time with a series production car, Jaguar gains entry through the '300kph exclusive club "of effortless performance of the supercharged 5.0-liter AJ-V8. A revised map half feeds the engine with direct injection and now 550P produces 680 Nm of torque. Recalibration extensive that have ensured the delivery of power and performance are transparent, which contributes to the hour 0 to 60 mph in 4.2 seconds. The active performance exhaust encourages and rewards the enthusiastic driver with The drama, inspired by the auditory feedback of motor sports.

Jaguar XKR-S is not only the fastest Jaguar ever, but also. More agile, responsive, focused and driver Pinnacle XK range is based on feedback from the supercharged XKR, and was developed to expand the parameters of performance of the car. This is a new cut harder nature of the enthusiastic driver that allows to investigate the dynamics of the external borders of the car without losing the sophistication and usability that Jaguar is renowned. The structural integrity of the lightweight aluminum frame does not interrupt work on a measure of components for increased stiffness without loss of the right or the refinement of Jaguar's legendary ride comfort. Custom aluminum front suspension knuckles and checked the back of the geometry of the Allies are stiffer springs and shock absorbers, forged alloy wheels and to adjust the control to minimize any delays in response and produce more, and the experience of handy guide.

Performance Jaguar XKR-S is specified as its interior and exterior design, which features a new paint colors that reflect the unique sporting heritage of Jaguar. As the Jaguars of the past competition, the outer surface of the XKR-S is consistent with the principle of function following form. In addition to design changes, and carry up to 300 km, the XKR-S has been extensively developed Computational Fluid Dynamics. Changes arising from the front and rear lift more than one quarter reduced, and optimized for lateral aerodynamic stability.

The performance for Jaguar XKR-S is clear from the moment the driver enters the cabin, with new seat performance with prominent shoulder blades cosseting for close support when cornering hard. The seats have 16-way adjustment, memory and functions of heating, while a new three-spoke steering wheel provides the perfect interface between car and driver.

Styling

Ian Callum, Design Director of Jaguar Cars, "The style of this car is not an image issue, it is true about the interpretation of other iconic Jaguar before it, the style was driven by pure geometry and aerodynamic design real physics required to reach 300kph .. led to the aesthetics, if you do not like how it looks, is probably not the way you drive. "

Jaguar's first fully designed under the Design Director Ian Callum the XK has won awards worldwide for its elegant appearance. Now change the style remains preserving the XKR-S at the forefront of modern sports car. Thinner, LED headlights, the main air intake and exhaust compact vertical electrical side contribute to a more specific look front. At the rear of the car's famous "Leaper" Jaguar is taking the place of honor in the center of the trunk lid.

The Jaguar XKR-S has also required changes to achieve aerodynamic speed 300kph above the imperturbable manner expected of a Jaguar and was designed with an eye only for the purity of line and the singularity of purpose. As the XKR-S is close to its maximum speed is not a requirement of proper air duct above, around and under the car to maintain stability and ensure a balanced front and rear support. A general reduction in the lift of 26 percent was achieved.

Revisions were made after the major CFD work, demonstrated by wind tunnel tests and are exclusive to the flagship XK. The most dramatic changes have been applied to the front of the car, to radically change their appearance and give a firmer appearance. A new bumper features vertical lines near the edges of execution according to the oval air intake and support the carbon fiber splitter and spoiler below. In the extreme edges of the front wings, vertical air channel slots on the sides of the car and throughout the sills, high-speed directional stability.

In order to balance front and rear lift, the Jaguar XKR-S has a separate wing on the back for the first time in the XK range. It also has carbon fiber center section, is working with the structure built similarly Venturi below the rear bumper.

Self-confident look of a new Jaguar XKR-S has been subtly highlight some carefully selected only the details of this model. Outdoor equipment is finished in gloss black, complete with 20-inch light alloy forged Volcano finishing techniques in the dark.

The XKR-S is available in a choice of five colors of paint, two of which evoke the heritage of Jaguar Racing: Racing Italian racing red and blue French.

As the lining of a suit, the finish is provided by the brake calipers, available in red or bronze and named "Jaguar."

Performance / Power Train

Russ Varney, Chief Engineer of the program, XK, "The XKR-S, we have exploited the inherent capabilities of the architecture of aluminum to its full extent to create a derivative of performance track-able to extend all the characteristics of the vehicle and offers an irresistible "smile of satisfaction 'driver's reaction. "

Amazing engines have always been a strong beating heart Jaguar road cars and racing from the record six-cylinder in the V12 XK120 smooth, XJ12, which was the fastest four-door in the world when he was launched.

The AJ-V8 has joined the illustrious list once the first shot in life, but the Jaguar XKR-S is presented in its most powerful to date. Now in its third generation with the addition of overeating, all-aluminum dual overhead cam engine provides not only performance but also by the piety of built-efficient technologies, including a jet-guided direct injection (SGDI) and two independent time variable cam (DIVCT).

Fuel is delivered to the center of the combustion chambers at pressures up to 150bar injection system for the center-mounted six-hole-driven jet in order to maximize the air-fuel mixture and improve responsiveness especially at low speed. Has also increased the compression ratio of 9.5:1 to 9.1:1 to improve fuel economy, while several injections to reduce the heating phase to increase the catalyst efficiency and reduce emissions.

All four camshafts has a variable distribution system, instead of being controlled by oil pressure, are activated by positive and negative torque generated by the movement of inbound and outbound, allowing smaller pump more efficient oil to be mounted, further reducing fuel consumption. VCT units meet three times faster than before, with activation rates of more than 150 degrees per second at each speed range, making the engine more responsive Jaguar has built, with no gaps of in the delivery of power.

As the vehicle itself, the AJ-V8 has an aluminum architecture with cast iron block, high pressure increased slightly in cast iron liners and cross-bolt main bearing caps that contribute to the sophistication to match with his power. The four-valve cylinder heads are made from recycled aluminum to reduce the environmental impact of motor manufacturing.

Located in the "V" of the cylinders are Roots-type compressor vortex and two twin intercoolers to help give XKR-S with such force intrusive. This unit of the sixth generation of forced induction is 20 percent more thermodynamically efficient than its predecessor, while intercoolers have their own cooling water to reduce the temperature of the compressed air to optimize power and efficiency.

Excess energy produced by this system meant that it was a relatively simple matter of releasing an additional 40PS and 55nm in the standard XKR. Reassignment fueling the engine and increases the flow of exhaust gases by using an active exhaust system has increased the total production of 5.0-liter V8 is now 550P and 680 nm, which drives the more Jaguar powerful ever made, and allowing the Jaguar XKR-S to hit 60 mph in 4.2 seconds and 300kph cross the magic barrier with ease.

The performance of an active exhaust system, which helps to provide these services will also produce an exciting Spirited motorsport-inspired soundtrack to the award sound the enthusiastic driver.

Treatment

Mike Cross, chief engineer for vehicle integrity, "This car includes everything a Jaguar should be performance, so capable, accurate and exciting on a wet Welsh B-road as it is the Nurburgring Any delay in the response was minimized to give. the car more connected with the way he runs, runs, stops and goes. "

Jaguar pioneered the use of aluminum construction for mass production cars, with low mass of metal and tensile strength to maximize the benefits in terms of performance, agility and fuel emissions.

Platform behind the XK range that makes a car's lighter and more rigid in his weight class in running order 1753kg and is the torsional rigidity of 28 400 newtons can Fri. This principle has allowed the strength of the team of Jaguar vehicles Integrity, led by Mike Cross, to develop the dynamic properties of the Jaguar XKR-S size, without compromising refinement. Every Jaguar achieved a superior blend of sportiness and luxury amenities, and the XKR-S is the most driver focused on Jaguar ever made.

When the solid foundation of an architecture based on aluminum, as well as front and rear suspension has been updated. Double wishbone front suspension is a magazine entirely new joint steering aluminum substantially increases the rigidity of the wheel camber and 0.13 degrees for each pound of Newton to change the resolution and greater emphasis on access control, feedback and precision. Active Differential Control is programmed to reduce the control sensitivity at very high speeds, the car that can, in addition to stability and driver control.

Geometry of the rear suspension was revised with the rear wheel steer optimized for maximum flexibility, while the spring rates were increased at both ends of the car by 28 percent. Custom software for the Jaguars adaptive damping that was written for the Jaguar XKR-S, which provides both total body control and maximum traction and grip.

Wheel sizes have only increased with Vulcan 20-inch forged alloy now have a width of nine-inch front and 10.5 inches rear for greater precision and control. The new wheels have Pirelli P Zero tires measuring 255/35 R20 front, 295/35 R20 rear. This combination reduces unsprung weight by 4.8 kg with an overall improvement proportional to the handling and dynamics.

Dynamic Stability Control System has been redesigned to maximize the benefit of wider tires. In the Trac DSC traction that specific user, stability and options to change the thresholds Edif slip, torque distribution and the difference in interference levels to provide the experienced driver to explore the outer edges of the envelope of performance and handling.

Jaguar XKR-S is a series of high-performance braking system. Lighter and more powerful, has a cast iron, and part of a one-piece aluminum calipers for a combination of strength, stability and feel. Brake discs - measuring 380 mm 376 mm front and rear - are ventilated to provide frequent and fade-resistant braking power. Together with the pad area increase of 44 percent front and 31 percent of the back system offers complete safety and confidence of cars and track. Stopping distance from 124 mph was improved by 2.7 percent XKR's already impressive.

The end result is a car that captures the essential duality that is characteristic of every great Jaguar, the driver can carry the legendary Nürburgring in comfort and silence, and yet able to offer a return period of less than and eight minutes and then go home with ease.

Internal

The cab of every Jaguar remains a unique place to spend a special time and the XKR-S meets all expectations at the time the driver enters to be greeted by the red button by pressing start as a heartbeat. Pressed, the engine starts with a deep, rich reverb movements Jaguar selector dial on the center console as the first point of contact to start the bonding process between man and machine.

The interior of the Jaguar XKR-S has been subtly refreshed with a host of new materials with ebony trim soft-feel paint for switches and high-gloss black finish for the center console. The model will be available exclusively with a linear dark aluminum finish as an option for the veneer.

The new leather steering wheel, multifunction steering wheel was also added, providing a nice tactile interface for a car with driver and clear, the Jaguar embossed, stainless steel pedals.

Exclusive Jaguar XKR-S are the new seats before the performance with an integrated headrest and the long side and back support to keep driver and passenger securely and comfortably in place during high speed corners where the car is capable . Set of 16 channels of chick cushion, lumbar and strengthen the elements are complemented with memory function and heating.

The timing in the development of the Jaguar XKR-S will be enhanced with hints of new leather carbon covering the seats with contrast piping unique microclimate and sewing combinations in Reims blue, red and ivory. Two-color combination of charcoal and charcoal with Tan with Red are also available.
