High-end refinement for a unique luxury sedan: STARTECH a BRABUS Group company, offers an exclusive sport and accessories program for the Jaguar XJ model series. The product lineup includes a strikingly styled aerodynamic-enhancement kit, custom-tailored 21-inch forged wheels and custom refinement options for the interior. The flat roofline that tapers off in the rear into a shape that approaches that of a fastback gives Jaguar a unique feature among luxury sedans that immediately catches the eye. The STARTECH designers have developed complementing body components that make the XJ even more unique. All aerodynamic-enhancement components are manufactured in OEM quality.
The nose of the four-door car receives some added profile with the STARTECH front attachment that is mounted to the production bumper. The component’s design with generously dimensioned air inlets lends the XJ a sportier appearance while its sophisticated shape reduces lift on the front axle. LED daytime running lights integrated into the side air inlets optimize active safety in traffic.
From the sides the English luxury sedan captivates with the STARTECH element for the front fenders. Its integrated air outlets lend the Jaguar XJ a sportier outfit. Design elements for the side sills attach in front of the rear wheel arches and complement the fender elements. An innovative STARTECH upgrade is also applied to the rear with a new fascia that has an integrated diffuser and two integrated ‘design’ panels with striking STARTECH looks. They are combined with two STARTECH stainless-steel rear mufflers.

A subtle rear spoiler lip on the trunk lid creates an optimal aerodynamic balance. To make full use of the available space in the wheel wells of the Jaguar XJ and to round out the STARTECH designer suit effectively, special version of the STARTECH Monostar J Diamond Edition wheels were developed. The three-piece forged wheels are mounted in sizes 9.0Jx21 and 10.5Jx21. They feature mirror-polished surfaces and titanium-look sections, and represent a perfect symbiosis of low weight and top quality. State-of-the-art forging technology makes these wheels especially light despite their high mechanical strength. The lower unsprung weight has positive effects on handling as do the wider high-performance tires in sizes 255/35 ZR 21 in front and 295/30 ZR 21 on the rear axle. The British luxury automobile also offers an excellent platform for exclusive interior refinement à la STARTECH. The interior designers offer a multitude of different leather and Alcantara colors, which are masterfully transformed by the company upholstery shop into custom interiors at the highest level of craftsmanship.
The show car features a black exterior and a contrasting STARTECH cream-colored all-leather interior made from especially soft and breathable Mastik leather. Two heated power business seats offer maximum comfort in the rear. A new center console with integrated storage compartments stylishly blends with the interior design. It is trimmed with the same leather used in the entire interior and features lights on either side that illuminate the floor in front of the individual rear seats.
Exquisite details are the precision-sewn seams on the dashboard and the sporty upholstery design of seats and leather flooring, which is stitched with unique precision using more than 5,000 meters of thread.
An absolute highlight that impressively demonstrates the quality of the STARTECH refinement is the elaborate wood trim for the sedan. Black, high-gloss polished piano wood was meticulously adorned by hand with ship-veneer-type inlays.

The STARTECH electronics specialists have developed a state-of-the-art multimedia system centered on an Apple iPad to give owners of a Jaguar XJ the opportunity to be always online or enjoy entertainment in the rear compartment. Electrically deployed tables, adapted perfectly to the back of the front seats with leather-trimmed consoles, feature custom-tailored recesses for the tablet computer and the Bluetooth keyboard from Apple.
A 20 MBit/s GSM modem with an antenna that has been integrated into the vehicle hidden from sight provides a high-speed internet connection via EDGE, HSDPA or HSPA+ protocols. Several passengers can communicate online at any time using a WLAN network available in and around the car.
STARTECH also offers a wide range of fancy accessories such as high-gloss polished stainless-steel scuff plates with backlit STARTECH logo and high-quality color-coordinated floor mats with leather borders. STARTECH aluminum pedals add notably sporty highlights.

2011 Jaguar C-X16 Concept

The Jaguar C-X16 Concept is a bold statement of Jaguar’s future design and technological intent. The C-X16 takes the traditional front-engined, rear-wheel drive formula that Jaguar defined over the decades and reinvents it for the 21st century in a performance-oriented hybrid drivetrain with 50:50 weight distribution.

The latest iteration of Jaguar’s ‘Redefining Performance’ ethos, the system is based around a prototype supercharged all-alloy V6 engine which produces 380 PS (280 kW) and 332 lb ft (450 Nm) of torque from 3.0-litres thanks to its innovative design. Supplementing this is an electric motor producing 70 kW and 235 Nm (equivalent to 95 PS and 173 lb ft), available to the driver at the push of a steering-wheel boost button.

Allied to an eight-speed gearbox and mounted in a lightweight aluminium chassis this allows the Jaguar C-X16 Concept to sprint to 62mph in 4.4 seconds and reach 186mph while returning 41mpg (UK gallon) and emitting 165g/km of CO2.

The aluminium bodywork is wrapped as closely to these mechanicals as possible to distil the essence of Jaguar sports cars into the next evolution of an already award-winning design language. By stretching the main feature lines back from the focal point formed by the grille and pushing the wheels as far into the corners as possible, the car has a taut, poised-for-action stance that is unmistakeably Jaguar.

The interior showcases important future technologies such as multimodal rotary controls. These incorporate miniature OLED screens, which reconfigure to reflect the different functions that can be performed via the controls, all of which are designed for maximum compatibility between sports car needs and everyday usability.

An example of this is the full smartphone integration via the ‘Connect and View’ system by which the central Touch-Screen reconfigures to mimic the screen of a connected device. The central screen also features a second-generation interface with fingertip touch supplemented by buttons that provide short cuts to top-level menu functions.

The cabin is trimmed in the finest leather and Suedecloth. As expected of a Jaguar, premium materials are used throughout, with the main touch surfaces composed of a combination of anodised aluminium, rich piano blacks, dark chrome and carbon-fibre that underline the car’s performance potential. The manually-adjustable bucket seats are made of lightweight composite materials with a central carbon-fibre spine for rigidity and support.

REDEFINING PERFORMANCE

“C-X16 draws inspiration from both our sporting qualities and our current leading-edge research into future powertrain technologies and consequently delivers an irresistible proposition on both emotional and rational levels.” – Adrian Hallmark, Global Brand Director, Jaguar Cars

The 2010 Jaguar C-X75 supercar concept presaged a game-changing approach to performance cars with its range-extending hybrid powertrain. Now, the C-X16 represents a further avenue of research in Jaguar’s mission to develop sustainable powertrain technologies and bring them to production.

The Jaguar performance ethos has its roots in the company’s Advanced Aluminium Architecture programme, which focuses on agility, power-to-weight and sustainability benefits. The Limo Green project, conducted in association with the Technology Strategy Board, combined this class-leading construction with a highly experimental hybrid powertrain that was further developed in the C-X75 supercar concept.

The next stage is represented here in C-X16 by real-world hybrid technologies that enhance the driving experience as well as the car’s environmental credentials.

HYBRID TRANSMISSION

The Jaguar C-X16 Concept signposts how the next generation of Jaguar sports cars will produce their power in an environmentally conscious manner. The concept is propelled by a hybrid powertrain that combines an all-alloy V6 engine with a performance-boosting electric motor inspired by the Formula One KERS system.

The purpose of this hybrid-performance system is threefold: to supplement the V6 engine’s already prodigious power through an on-demand ‘Push to Pass’ system; to reduce fuel consumption; and to allow the C-X16 to perform as a zero tailpipe-emissions electric vehicle at speeds of up to 50mph on low throttle openings.

Intelligent Stop/Start

The starting point is Jaguar’s eight-speed transmission with Intelligent Stop/Start, recently launched to great acclaim in the XF sports saloon. The system can shut down the engine in just 300 milliseconds after the car has come to rest and utilises a Twin Solenoid Starter (TSS) that is capable of restarting it in the time it takes the driver’s foot to travel from the brake to the accelerator. This provides for faster recovery and seamless performance beyond the capabilities of any existing competitor in production and is the first time such a system has been used with a supercharged engine.

Energy Recovery

The Jaguar C-X16 Concept extends the Stop/Start system’s functionality by linking it to a transmission-integrated motor generator mounted as one unit with the gearbox. This draws power from a 1.6kWh lithium-ion battery pack mounted behind the seats for perfect weight distribution.

As in the most demanding motorsport environment, Jaguar employs a Kinetic Energy Recovery System (KERS). The battery pack is predominantly charged through a rear axle electro-hydraulic brake energy regeneration system.

Performance on demand

A dashboard display graphic indicates when the additional boost provided by the electric motor can be deployed. When charged, a ‘Push to Pass’ boost button mounted on the steering wheel allows access to an additional 70kW and 235Nm of torque (equivalent to 95PS and 173lb ft) for up to 10 seconds. Because of the lag-free nature of an electric motor, this power is instantaneously available. The battery is constantly and automatically recharged, the entire system overseen by a Hybrid Vehicle Supervisory Controller.

Both the battery pack and electric motor mounted in the Jaguar C-X16 Concept are liquid cooled preventing them losing performance as heat builds up during spirited use. To cool the battery the advanced electronics draw chilled coolant from the climate-control system, the compressor for which is itself electrical rather than engine-driven to reduce losses. The hybrid system is placed within the wheelbase of the car to aid weight distribution and maximise agility by reducing the polar moment of inertia.

SUPERCHARGED V6

The front-mounted supercharged V6 engine develops 380PS (280kW) and 332lb ft (450Nm) of torque from a capacity of 3.0-litres. A modular development of the award-winning Jaguar AJ-V8, the all-new powerplant points the way to the next generation of highly efficient, powerful, petrol-fuelled internal combustion engines.

The new V6 is of the same lightweight aluminium architecture as the eight-cylinder engine with a high-pressure, die-cast block with cross-bolted main bearing caps for increased strength and refinement. The quad-cam, four-valve-per-cylinder heads are constructed from recycled aluminium to reduce the environmental impact of manufacturing.

Optimised for bore and stroke, the V6 also features a second-generation Direct Injection combustion system with a raised compression ratio of 10.5:1. A revised electronic bypass for the sixth-generation twin vortex Roots-type supercharger allows much more precise boost control to reduce fuel consumption.

Performance and Refinement

These advances in efficiency allow the V6 to produce a specific power output of 126PS per litre. Allied to the performance-boosting electric motor the result is astonishing – 0-62mph in 4.4 seconds, a limited top speed of 186mph and in-gear acceleration of just 2.1 seconds between 50 and 75mph. The benefits of the hybrid system extend beyond being merely sporting, reducing CO2 emissions to 165g/km and returning 41mpg on the combined cycle.

To ensure the powerplant delivers not only the power but also the refinement that Jaguars are famous for, the V6 features a patented system of independently rotating balancer weights at the front and rear of the engine. Anyone familiar with the smooth, powerful V8 will find that the V6 shares all its power delivery and refinement characteristics, with of course its own stirring soundtrack, while delivering significantly improved fuel consumption and emissions meeting SULEV 30 and EU VI standards.

DESIGN

“This car has been designed from first principles. It is an evolution of the design ethos of past Jaguars and defines the agenda for a future of dramatic, innovative sports cars. Purity of line and intent is what Jaguar does best.” – Ian Callum, Director of Design, Jaguar Cars

If anything can be said to define Jaguar designs it is one word: drama. The Jaguar C-X16 Concept is no exception, taking the traditional two-seater sports car template and redefining it in the Jaguar idiom.

In its simplest form, sports car design is defined by the relationship between the mechanicals and the bodywork. The aim at Jaguar has always been to wrap the form as tightly as possible around the function to create a taut, sculpted appearance that could only be that of a Jaguar. Finished in Gunmetal, there is no wasted space, movement or surface on the Jaguar C-X16 Concept, every line serves its purpose in creating a whole that is more than the sum of its parts.

Purity of Line

The Jaguar C-X16 Concept moves the award-winning Jaguar design language on to the next level and is startling in its simplicity, defined as it is by three ‘heartlines’; the front wing crease, the rear haunches that wrap into the tail and the sweeping roofline.

“The stance of this car is everything. It is fundamentally a driving machine and that has driven every aspect of the design. We have pulled the three signature heartlines back as far as we can to create a dynamic tension. The car possesses a sense of latent power; the potential to leap instantly into action.” – Ian Callum, Director of Design, Jaguar Cars

The Jaguar C-X16 Concept also makes use of newly established Jaguar styling signatures such as the subtly rounded trapezoidal grille. Inspired by the C-X75 concept car and recognisably related to the current XF and XJ, this is the focal point for the front end of the car, providing instant rear view mirror recognition.

Muscular Definition

The muscular clamshell bonnet is defined at the outer edges by two sharp creases rising along the upper edges of the front wings. These begin in the gill-like strakes dividing the air intakes flanking the grille before blending away into the shoulder line running along the doors. The importance of this front wing line is emphasised by the angular form of the headlights, which deliberately follow the rising wing to lead the eye up and along the contours of the car rather than cut across them.

The horizontal front wing vents, like those in the bonnet, are finished in carbon-fibre.

The defining role of the front wing line is taken up by a further finely chiselled crease that forms a double ‘coke-bottle’ curve, swelling outwards and upwards from the waist of the car to encompass the muscular haunches that are a Jaguar hallmark. This feature line then swoops, unbroken, round the rear of the car to create the tail, which mimics the appearance of the trailing edge of a swept aeroplane wing.

The rear lights continue the theme set with the C-X75 by extending around the flanks of the car immediately below the tail crease to literally highlight the powerful width of the rear track and, like the grille, provide instant recognition that this is a Jaguar sports car.

Aerodynamic Simplicity

In order to retain the unblemished muscularity and uninterrupted airflow along the flanks of the car, the door handles are entirely flush with the bodywork. Touch sensors built into the handles trigger silent electric motors, which present the machined aluminium handles to driver and passenger.

The same desire for stunning simplicity has driven the aerodynamic element of the Jaguar C-X16 Concept’s design, with no unnecessary wings or spoilers. Downforce is provided by a discreet front splitter, Venturi-effect tail design and side sills to channel air smoothly along the car’s flanks, all of which are finished in carbon fibre. The sharp crease created where the curve of the roof meets the tail also aids the aerodynamics by ensuring the air separates cleanly from the bodywork at high speed.

Even standing still, the sense of purpose and power inherent in the Jaguar C-X16 Concept is unmistakeable thanks to a stance that optimises the relationship between the bodywork and the 21-inch alloy wheels which have been pushed to the extremes edges of the car and finished with a carbon-fibre inlay.

INTERIOR

The singularity of purpose exhibited by the exterior styling of the Jaguar C-X16 Concept is reinforced the moment the door is opened, whereupon driver and passenger are greeted by a dramatic red interior trimmed in the finest materials; leather, Suedecloth, anodised machined aluminium, carbon-fibre and dark chrome.

Vermillion Red Interior

The car is clearly centred around the driver and underlines its ‘One plus One’ layout by deliberately creating as cocooned and cosseting a space as possible. The heart-stirring potential of the C-X16 is underlined by the choice of visceral Vermillion Red as the primary colour and trim theme throughout.

Aircraft-inspired Layout

The Jaguar C-X16 Concept takes inspiration for elements of its layout from aeronautical ergonomics, such as the joystick-style gearlever and banks of toggle switches that also reference classic racing Jaguars. As a result of this thinking the dashboard has been shrink-wrapped around the driver to provide the best view forward, allowing the car to be placed with absolute precision in corners, aided by the sharp creases on top of the front wings.

The desire to keep the top of the dashboard as unadorned as possible led to the creation of an Intelligent Venting System. Governed by complex algorithms built in to the advanced climate control, this double vent – inspired by the intakes on the Typhoon fighter jet – deploys out of the dash to provide an intense blast of hot or cold air as needed to rapidly alter the cabin temperature and then discreetly retracts when the desired level is reached.

In the same way that the exterior door handles are concealed until activated, a desire for ergonomic clarity means aspects of the interior remain ‘secret until required’. Pushing the starter button initiates an aircraft-inspired starting sequence that powers up the hidden-until-lit displays in a cascade down the centre console. What looks at first sight like a TFT screen in front of the driver is revealed to be an elegant twin-dial instrument panel, a hallmark of Jaguar sports cars, hidden behind smoked glass.

Dual-function Switchgear

With Jaguar already a leader in Touch-Screen technology, the C-X16 features the next generation of the system, augmenting the central screen with two rows of ‘Home’ keys on either side that provide shortcuts to top-level menu functions. Further controls take their inspiration from devices such as smartphones and tablets and provide multimodal functionality.

The rotary heating controls are made from machined aluminium and anodised in dark gunmetal; traditional materials but in the centre of each is a miniature OLED display which reconfigures according to how the controls are used. Rotating the controls alters the temperature on respective sides of the car but pushing them changes their functionality; they now control the heating and cooling functions of the seats.

The switchgear is framed in carbon-fibre and features subtle ‘watch-like’ dark chrome highlights while the gearlever and dynamic mode selector switch are surrounded by red anodised aluminium to emphasise their purpose.

Connectivity

The centre console armrest houses Jaguar’s ‘Connect and View’ system. Developed in conjunction with Blackberry™, this allows smartphones from a range of manufacturers to be plugged into the machined aluminium tray between the front seats, whereupon the central Touch-Screen reconfigures to reflect that phone’s display. The system will communicate with the majority of the smartphone’s functions and has the potential to deliver a host of features dependent on the market and the device.

Carbon-fibre construction

Made from lightweight composite materials the close-fitting and supportive racing seats feature manual adjustment to further reduce weight. A central carbon-fibre spine runs up the centre of each seatback to reinforce it.

The structural properties of carbon-fibre are further utilised in a bracing bar that flows back from the centre console dividing the seats and then splits in two, before being bolted to the rear suspension turrets to provide additional rigidity. Further carbon-fibre is found in the centre console, framed by the tailored passenger grab handle that flows organically from the dashboard to the transmission tunnel. The floor is finished in aluminium and black Poltrona Frau leather that has been subtly hand quilted with a Hex pattern influenced by the historic Jaguar lozenge – this same motif is found stitched into the Suedecloth headlining.

Nestled discreetly behind the front seats are the lithium-ion battery pack and inverter that provide power to the hybrid drive system. Positioned here for optimum weight distribution, they are hidden under an aluminium cover machined from solid and designed with integral heat sinks.

2012 Jaguar XKR

JAGUAR Reageren uitgeschakeld

aug 162011

The Jaguar XK was the first car created entirely under the aegis of Design Director Ian Callum. Dramatic and purposeful, yet as sensuous as only a Jaguar can be, the XK now receives a number of revisions that reinforce its contemporary, assertive character.

The latest lighting technology has allowed the front headlamps to be made slimmer and at the same time incorporate LED signal functions and running lights. Combined with a larger grille and new bumper design, this gives the XK instant ‘rear-view mirror’ recognition. Unmistakably a Jaguar, each model in the range gains unique styling attributes that distinguish it from its siblings. Chrome mesh grilles on the XK are replaced with matt black detailing on the XKR while the flagship XKR-S receives a unique front bumper underlining its sense of purpose.

The power vent along the front wing has been altered from a vertical to horizontal design with a mesh insert. Emblazoned with the Jaguar name, it serves to emphasise the potential inherent in the XK’s design. To the rear, the boot lid has been revised with a slimmer chrome finisher which allows the car to be graced by the famous Jaguar ‘leaper’, bringing it into line with the rest of the company’s products.

Complementing the design changes are 17 paint colours, five of which are new and a range of alloy wheels that now total 11 different designs ranging in size from 18 to 20 inches. A further opportunity for owners to express their individuality is available through the ‘Black Pack’, now also available as an option on the naturally aspirated cars as well as the Jaguar XKR. This replaces exterior chrome with a matt black finish, complemented by 20-inch gloss black alloy wheels. On the Jaguar XKR, the package also includes body coloured aerodynamic enhancements and optional side graphics.

XK Powertrain and Dynamics

Jaguar sports cars have a reputation for blending athletic high-performance with effortless cruising comfort. Nothing exemplifies this dual character more clearly than the XK’s 5.0-litre AJ-V8 engine. Now in its third generation this offers not only tremendous power but also great efficiency by incorporating the very latest technology including spray-guided direct injection (SGDI) and dual independent variable cam timing (DIVCT). Like the car itself, the engine is constructed from high-grade, lightweight aluminium, which in the cylinder heads is recycled to reduce the environmental impact of manufacture.

New 186mph XKR-S

Available in both naturally aspirated and supercharged forms from the beginning, the engine is now offered in a third variant in the XKR-S. Based on the supercharged unit in the Jaguar XKR, revised fuel mapping and an active exhaust have boosted power and torque to 550PS and 680Nm respectively, creating the most powerful Jaguar road car ever. This allows the car to reach 60mph in just 4.2 seconds and join the exclusive ’300km/h’ club with a limited top speed of 186mph. Not only extremely powerful but also efficient, the XKR-S emits just 292g/km of CO2.

All variants of the XK use the six-speed ZF automatic gearbox with steering wheel-mounted paddles to control the Jaguar Sequential Shift function for greater driver control. In the XKR-S the transmission has been revised in line with the increased power and torque to optimise upshifts and allow for the increased top speed.

The XK’s exhilarating driving dynamics are the result of the latest generation of Jaguar’s Adaptive Dynamics technology that provides a continuous and seamlessly variable damping strategy to negate the traditional trade-off between ride comfort and handling.

Luxury and performance duality

Adaptive Dynamics performs three main functions; controlling vertical body movement, roll and pitch rates. One hundred times every second, Adaptive Dynamics analyses the thousands of inputs and variables which determine ride and handling characteristics. By also monitoring wheel position 500 times every second, the system is able to achieve the famous Jaguar duality between comfort and sporting appeal. Should the driver wish to alter these characteristics, there is the option of Dynamic Mode, which increases body control, sharpens throttle response and reduces gearshift times.

The two supercharged variants of the XK also benefit from Jaguar’s Active Differential Control technology. This uses a multiplate clutch to vector torque to the driven wheel with the most grip. Allied to the ABS and stability control, this allows for the ultimate in traction and precision both mid-corner and at its exit. Non-supercharged models use a mechanical differential, which delivers outstanding levels of grip and stability under power.

All models benefit from the Dynamic Stability Control system which offers four modes: normal, Winter, TracDSC and DSC Off, allowing the enthusiastic driver to choose the level of intervention dependent on road conditions.

The XKR-S model enhances both these electronic systems and the inherent stiffness of the lightweight aluminium architecture to create the most dynamic and exciting Jaguar yet.

Uprated suspension

The double wishbone front suspension has been comprehensively revised with a new fully-machined steering knuckle. This significantly increases camber and castor stiffness by 0.13 degrees per kilonewton to transform the accuracy and weighting of the steering for greater levels of connection, feedback and precision. Rear suspension geometry has been revised with rear wheel steer optimised for maximum agility while spring rates have been increased at both ends of the car by 28 percent.

The Active Differential has been programmed to reduce steering sensitivity at the very high speeds of which the car is capable, increasing stability and driver control. Bespoke software for Jaguar’s Adaptive Damping has been written for the XKR-S, ensuring both total body control and maximum traction and grip. Changes to the TracDSC mode alters intervention levels to allow the experienced driver to explore the outer edges of the performance envelope, rewarded by the motorsport inspired soundtrack from the exhaust, which features an active pneumatic valve.

The suspension changes and Performance exhaust system are available as part of the Dynamic Pack option for the Jaguar XKR model.

“The XKR-S encompasses everything a performance Jaguar should be; as capable, precise and thrilling on your drive home as it is at the Nürburgring. Every response delay has been minimised in order to give the car a more connected feel in the manner in which it steers, handles, stops and goes.” Mike Cross, Chief Engineer, Vehicle Integrity

XK Interior

The dual nature of the XK is apparent from the moment the driver enters the cabin. Luxurious and cocooning, the sporting potential is apparent from the moment the Start button pulses red. Pressing it fires the engine into life with a deep, musical reverberation and the Jaguar DriveSelector rises from the centre console as a point of first contact to begin the process of bonding man with machine.

In the latest XK, the cabin has been refreshed with a host of new trim materials including ebony soft-feel paint for the switches, gloss black finish to the centre console and phosphor blue halo illumination and ambient lighting. New veneers, colour combinations and headlining options allow owners to create a cabin ambience precisely matching their requirements.

A new leather-wrapped, multi-function steering wheel has also been added, providing a tactile interface between car and driver, complemented on the XKR-S by ‘Jaguar’ embossed stainless steel pedals, which are optional on other models.

New performance interiors

Standard on the XKR-S and optional on the XKR and XK Portfolio models are the new Performance front seats. Featuring integrated head restraints and increased lateral and squab support, the new seats hold driver and passenger securely and comfortably in place. The 16-way adjustment of squab, cushion, lumbar and bolster elements is supplemented by memory and heating functions. Unique to the XKR-S is a Carbon patterned and soft-grain leather interior with contrasting micro-piping and stitching. The Jet Poltrona Frau Italian leather headlining that is standard on the XKR-S is offered as an option on other models.

The central seven-inch Touch-screen provides an intuitive interface for the extensive technology that is seamlessly incorporated into the XK, including iPod and USB connectivity and satellite navigation with DVD mapping. The central screen also projects the image from the new reverse parking camera.

2012 Jaguar XKR-S

2012 Jaguar XKR-S

Making its debut at the 2011 Geneva Motor Show, the Jaguar XKR-S is the most extreme expression yet of Jaguar’s passion for building beautiful, fast cars. For the first time with a series production car, Jaguar gains entry to the exclusive ’300kph club’ thanks to the effortless performance of the supercharged 5.0-litre AJ-V8 engine. A revised fuelling map means the direct-injection powerplant now produces 550PS and 680Nm of torque. Extensive recalibration has ensured that power delivery and performance are seamless, contributing to a 0-60mph time of 4.2 seconds. The Performance active exhaust encourages and rewards the enthusiastic driver with dramatic, motorsport-inspired aural feedback.

The Jaguar XKR-S is not merely the quickest Jaguar ever but also the most agile, responsive and driver-focused. The pinnacle of the XKrange builds on feedback gathered from the supercharged XKR and has been developed to extend the performance parameters of the car. This new harder-edged character allows the enthusiastic driver to explore the outer limits of the car’s dynamics without losing the refinement and usability for which Jaguar is famous. The structural integrity of the lightweight aluminium platform allowed the suspension to be reworked with bespoke components for increased stiffness without a commensurate loss in either refinement or Jaguar’s legendary ride comfort. A reworked aluminium front suspension knuckle and revised rear geometry are allied to stiffer springs and dampers, lightweight forged alloy wheels and recalibrated steering effort to minimise any response delays and produce a more connected and agile driving experience.

The performance of the Jaguar XKR-S is reflected in both its interior and exterior styling, which feature exclusive new paint colours that reflect Jaguar’s racing heritage. As with competition Jaguars of the past, the exterior of the XKR-S adheres to the principle of form following function. In addition to the styling changes and in order for it to achieve 300kph, the XKR-S was the subject of extensive Computational Fluid Dynamics development work. The resulting changes reduced front and rear lift by more than a quarter and optimised lateral aerodynamic stability.

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

Styling

Ian Callum, Design Director, Jaguar Cars: “The styling of this car isn’t about image, it’s about true performance. Like other iconic Jaguars before it, the styling has been driven by geometry and aerodynamics for genuine design purity. The physics required to achieve 300kph have led the aesthetic; if you don’t like the way it looks, you probably won’t like the way it drives either.”

The first Jaguar designed entirely under the aegis of Design Director Ian Callum, the XK has received awards worldwide for its elegant appearance. Now further styling changes keep the XKR-S at the forefront of modern sports car design. Slimmer, LED headlights, more compact main air intake and vertical side power vent all contribute to a more purposeful front-end appearance. At the rear of the car the famous Jaguar ‘Leaper’ now takes pride of place in the centre of the bootlid.

The Jaguar XKR-S also required aerodynamic modifications to achieve its 300kph top speed in the unruffled manner expected of a Jaguar and has been designed solely with an eye for purity of line and singularity of purpose. As the XKR-S approaches its top speed, there is a requirement to channel air cleanly over, around and under the car in order to maintain stability and ensure balanced downforce front and rear. An overall reduction in lift of 26 per cent has been achieved.

The necessary revisions were made after extensive Computational Fluid Dynamics work, proven through wind tunnel testing and are unique to this flagship of the XK range. The most dramatic changes have been applied to the front of the car, radically altering its appearance and lending it a more assertive look. A new bumper design features near vertical feature lines running down from the edges of the oval air intake and supporting the new carbon-fibre splitter and lower spoiler. At the extreme edges of the front fenders, vertical slots channel air down the sides of the car and along the wider sills for increased high-speed directional stability.

In order to balance front and rear lift, the Jaguar XKR-S features a separate rear wing, a first for the XK range. This addition, with its carbon-fibre centre section, works in concert with the similarly constructed Venturi structure underneath the rear bumper.

The assertive new appearance of the Jaguar XKR-S is subtly highlighted by some carefully chosen details exclusive to this model. Exterior trim is finished in gloss black, complemented by 20-inch Vulcan lightweight forged alloys in a dark technical finish.

The XKR-S is available in a range of five paint colours, two of which evoke Jaguar’s competition heritage: Italian Racing Red and French Racing Blue.

Like the lining of a bespoke suit, the finishing touch is provided by the brake calipers, available in either red or gunmetal and emblazoned with the ‘Jaguar’ name.

Performance/Powertrain

Russ Varney, Chief Programme Engineer, XK: “With the XKR-S we have exploited the inherent capabilities of the aluminium architecture to its fullest extent to create a track-capable performance derivative extending all car’s attributes and delivering an irresistible ‘smile of satisfaction’ response from the driver.”

Astonishing engines have always formed the strongly beating heart of Jaguar’s road and race cars from the record-setting straight-six in theXK120 to the smooth V12 that made the XJ12 the fastest four-door in the world when it was launched.

The AJ-V8 joined this illustrious list from the moment the first one was fired into life but in the Jaguar XKR-S it is presented in its most potent form to date. Now in its third generation and with the addition of supercharging, the all-aluminium quad-cam powerplant delivers not only extreme performance but also tremendous efficiency thanks to the technologies incorporated into it, including spray-guided direct injection (SGDI) and dual independent variable cam timing (DIVCT).

Fuel is delivered directly to the centre of the combustion chambers at a pressure of up to 150bar by the centrally-mounted six-hole spray-guided injection system in order to maximise fuel-air mixing and improve responsiveness, particularly at low speeds. It has also allowed an increase in compression ratio from 9.1:1 to 9.5:1 to improve fuel economy while multiple injections reduce the warm up phase to increase catalyst efficiency and reduce emissions.

Each of the four camshafts features a variable timing system which rather than being controlled by oil pressure, are activated by the positive and negative torques generated by the movement of the intake and outlet valves, allowing for a smaller, more efficient oil pump to be fitted, further reducing fuel consumption. The VCT units respond up to three times faster than previously with actuation rates of more than 150 degrees per second at every point in the speed range, making this the most responsive engine Jaguar has ever built, with no gaps in its power delivery.

Like the car itself, the AJ-V8 features aluminium architecture with the high pressure die-cast lightweight block augmented by cast iron liners and cross-bolted main bearing caps which contribute to refinement to match its power. The four-valve cylinder heads are now constructed from recycled aluminium to reduce the environmental impact of engine manufacture.

Nestling in the ‘V’ of the cylinders is the Roots-type twin vortex supercharger and its two intercoolers that help provide the XKR-S with such urgent motive power. This sixth-generation forced induction unit is 20 per cent more thermodynamically efficient than its predecessor, while the intercoolers feature their own water-cooling circuit to reduce the temperature of the pressurised air to optimise power and efficiency.

The surfeit of power produced by this system meant that it was a relatively simple matter to liberate an extra 40PS and 55Nm over the standard XKR. Remapping the engine’s fuelling characteristics and increasing exhaust gas flow through the use of an active exhaust system has lifted total output of the 5.0-litre V8 is now 550PS and 680Nm, making it the most powerful Jaguar road engine ever made and allowing the Jaguar XKR-S to hit 60mph in 4.2 seconds and breach the magical 300kph barrier with ease.

The Performance active exhaust system that helps provide such spirited performance also produces a thrilling motorsport-inspired soundtrack to aurally reward the enthusiastic driver.

Handling

Mike Cross, Chief Engineer, Vehicle Integrity: “This car encompasses everything a performance Jaguar should be; as capable, precise and thrilling on a wet Welsh B-road as it is at the Nürburgring. Every response delay has been minimised in order to give the car a more connected feel in the manner in which it steers, handles, stops and goes.”

Jaguar pioneered the use of aluminium construction for series production cars, exploiting the metal’s low mass and high tensile strength to maximise benefits in terms of performance, agility, fuel consumption and emissions.

The platform underpinning the XK range makes the car one of the lightest and most rigid in its class with a kerb weight of 1753kg and torsional stiffness of 28,400 Newtons per degree. This fundamental strength allowed Jaguar’s Vehicle Integrity team, led by Mike Cross, to develop the dynamic attributes of the Jaguar XKR-S to the full, without affecting refinement. Every Jaguar achieves an unrivalled mix of sporting appeal and luxurious comfort and the XKR-S is the most driver focused Jaguar ever made.

Taking the solid foundation of the aluminium architecture as a starting point, both front and rear suspension systems have been upgraded. The double wishbone front suspension has been comprehensively revised with a new aluminium steering knuckle that significantly increases camber and castor stiffness by 0.13 degrees per Kilonewton to transform the accuracy and weighting of the steering for greater levels of connection, feedback and precision. The Active Differential Control has been reprogrammed to reduce steering sensitivity at the very high speeds of which the car is capable, increasing stability and driver control.

Rear suspension geometry has been revised with rear wheel steer optimised for maximum agility while spring rates have been increased at both ends of the car by 28 per cent. Bespoke software for Jaguar’s Adaptive Damping has been written for the Jaguar XKR-S, ensuring both total body control and maximum traction and grip.

Wheel sizes have been increased with the unique lightweight forged Vulcan 20-inch alloys now having a width of nine inches at the front and 10.5-inches at the rear for greater precision and grip. The new wheels wear Pirelli P Zero tyres measuring 255/35 R20 at the front, 295/35 R20 at the rear. This combination has reduced overall unsprung mass by 4.8kg with a commensurate improvement in handling and dynamism.

The Dynamic Stability Control System has been reworked to maximise the benefit of these wider tyres. In Trac DSC mode this utilises specific traction, stability and eDiff settings to alter slip thresholds, differential torque distribution and intervention levels to allow the experienced driver to explore the outer edges of the performance and handling envelope.

The XKR-S is equipped as standard with Jaguar’s High Performance Braking System. Lighter and more powerful, this features cast iron and part aluminium monobloc calipers for a combination of power, stability and feel. The brake discs – measuring 380mm at the front and 376mm at the rear – are internally ventilated to provide repeated, fade-free stopping power. In combination with pad surface increases of 44 per cent front and 31 per cent rear the system provides total security and confidence on both road and track. Stopping distance from 124mph has been improved by 2.7 per cent over the already impressive XKR.

The end result is a car that captures the essential duality that is a characteristic of every great Jaguar; capable of transporting the driver to the fabled Nürburgring in total comfort and hushed silence, and yet still able to deliver a sub-eight minute lap time and then return home with total ease.

Interior

The cabin of any Jaguar is always a uniquely special place in which to spend time and the XKR-S meets all expectations from the moment the driver enters to be greeted by the red Start button pulsing like a heartbeat. When pressed, the engine fires with an rich, deep reverberation and the Jaguar Drive Selector rises from the centre console as a point of first contact to begin the process of bonding man with machine.

The interior of the Jaguar XKR-S has been subtly refreshed with a host of new trim materials including ebony soft-feel paint for the switches and gloss black finish to the centre console. The model will also be exclusively available with a Dark Linear Aluminium finish as an option to the wood veneers.

A new leather-wrapped, multi-function steering wheel has also been added, providing a beautiful, tactile interface between car and driver as do the bright, Jaguar-embossed, stainless steel pedals.

Exclusive to the Jaguar XKR-S are the new Performance front seats with an integrated head restraints and increased lateral and squab support to hold driver and passenger securely and comfortably in place during the high speed cornering of which this car is capable. The 16-way adjustment of squab, cushion, lumbar and bolster elements is supplemented by memory and heating functions.

The sense of occasion offered when driving the Jaguar XKR-S will be heightened by the new carbon leather accents covering the seats, featuring unique contrast micro-piping and stitching combinations in Reims Blue, Red and Ivory. Duotone combinations of Charcoal with Tan and Charcoal with Red are also available.

2010 Startech Jaguar XK XKR

Exclusive, Innovative and Individual: The STARTECH Program for all Jaguar XK and XKR Models

Exclusive, innovative and individual: These three attributes best describe the STARTECH accessories program for the latest Jaguar XK and XKR models, which is available for coupes and convertibles. A customized XK Coupe that celebrates its world debut at the Frankfurt Motor Show IAA 2009 in Frankfurt/Main gives a good first look at the complete product lineup for the British automobiles. The engineers and designers from STARTECH (www.startech.de) have developed subtle sporty body modifications, custom-tailored 21-inch forged wheels with corresponding ride-height lowering and eye-catching interior options.

Adding sporty emphasis to the elegant lines of the two-door with subtle components was a challenge the STARTECH styling team mastered with great success. The team developed spoiler flaps that attach to both sides of the production front apron. They upgrade the car’s appearance and reduce lift on the front axle.

All STARTECH aerodynamic-enhancement components are made from carbon fiber. To make these components not only ultra-light but also extremely strong STARTECH uses the same ‘Prepreg’ production process in an autoclave used in motor racing and aerospace engineering. The face of the Jaguar is further upgraded with daytime running lights. Using precise-fit design elements these lights are beautifully integrated into the stylized air vents on both sides of the bumper.

The STARTECH carbon-fiber rear molding serves as the perfect backdrop for the two tailpipes of the exhaust system and gives the rear of the Jaguar even more character.

The exclusive STARTECH looks are further characterized by STARTECH forged wheels custom-tailored for the XK models. The three-piece Monostar J Diamond Edition wheels intersperse polished surfaces with brushed-look sections and are miles apart from the rest. The same is true for the wheel sizes, which were selected specifically for the sportiest Jaguar model. The front wheel houses are filled to the max by size 9Jx21 wheels with tires in size 255/30 ZR 21. In the rear tires in size 295/25 ZR 21 mounted on size 10.5Jx21 wheels strive to provide maximum traction.

STARTECH sport springs are specially calibrated to these tire/wheel combinations. They lower the ride height of both body styles by some 40 millimeters (1.6 inches). Exclusive interiors are a particular STARTECH specialty. The interior designers transformed trends from exclusive high-end living into the XK without overpowering the sports car’s British character. The company upholstery shop has created a fully leather interior made from the finest, especially soft brandy-colored leather. A new combination of contrasting cords and double seams using an especially thick thread creates an entirely new and yet very English ambiance in the cockpit.

The STARTECH interior program also offers countless other color combinations in leather and Alcantara. More than 100 different colors are always in stock, special requests such a leather color that matches a favorite lipstick or other item can also be fulfilled.

New bamboo wood trim elements replace the precious-wood and aluminum trim available from the factory. The wood color is specially matched to the brandy-colored leather. A special bleaching and staining process makes it possible to match the leather color exactly. This STARTECH innovation also gives customers a choice of open-pore, matte or high-gloss surface finishes. Genuine carbon-fiber trim sets with different structures and colors are yet another option for customizing the interior. Further exclusive ideas for the interior are scuff plates with illuminated STARTECH logo and high-quality floor mats bordered with color-coordinated leather.
