For the 2006 Model Year, the XJ range expands to six distinct model derivatives with the addition of the limited edition, ultra-exclusive Super V8 Portfolio. Apart from the short-wheelbase XJ8 and supercharged, high-performance XJR, the XJ line-up is made up of the exceptionally spacious long wheelbase models – the XJ8 L, Vanden Plas, Super V8 and new Super V8 Portfolio.

Among the extended line-up, each XJ model continues to build upon its technical prowess for the 2006 model year with the addition of an array of subtle but effective safety, performance and refinement enhancements. A number of subtle exterior design changes also give the XJ a fresher, more contemporary look.

The XJ Long Wheelbase is the natural fit for the Jaguar driver who enjoys the focused driving dynamics of the standard wheelbase XJ sedan, but prefers the additional rear seat room, and the added opportunity of using the back seats as a traveling office or meeting room.

The long wheelbase XJs offer exceptional rear seat legroom while retaining the dynamic character, style and everyday drivability of the standard wheelbase XJ. And, like the standard wheelbase models, the long wheelbase XJs share all the benefits of advanced aluminum-intensive construction, light weight, massive body strength, comprehensive safety features, refined performance and agile driving dynamics.

XJ RANGE CONTINUES TO STRETCH ITS APPEAL

Visual enhancements for the 2006 model year XJ give the flagship sedan a cleaner, fresher, more contemporary look. In keeping with all 2006 Jaguars, the XJ gets a new ‘face’ with the switch to chrome mesh grille inserts across the range. The supercharged XJR continues to be distinguished by its body-colored surround for its mesh grille.

For 2006, body side moldings and front and rear windshield finishers have also been removed to enhance the cleaner look of the vehicle. Four new colors are added to the XJ’s palette, with Winter Gold replacing Topaz, Indigo Blue replacing Pacific Blue, liquid silver replacing Platinum at mid-year and Black Cherry unique to the Super V8 Portfolio.

In addition, two new wheel styles have been added – the standard wheel for the XJ8 and XJ8 L is a new 15-spoke, 18-inch ‘Tucana’ style alloy wheel, while the standard XJR wheel for 2006 is the five-spoke, 19-inch ‘Sabre’ style alloy wheel. The bold 20-inch ‘Sepang’ style alloy wheel is available for the first time on the Super V8 as an option. A chromed version of the 19-inch 'Custom' style alloy wheels is also now available as an option.

The XJ sedan's elegant lines are enhanced by the increased length - with the car's greenhouse now perfectly balanced across the B-post, which simply confirms the long wheelbase version's luxurious, dynamic, distinctively Jaguar character.

To add the required extra space and equipment, while retaining the dynamic character, the style and the everyday drivability of the standard wheelbase XJ, Jaguar increased the original wheelbase by 5 inches to 124.4 inches, and overall length by the same amount to 205.3 inches. That makes the XJ Long Wheelbase the longest car in its premium sedan class - 2.0 inches longer than the long version of the current Mercedes Benz S-Class and 1.4 inches longer than the longest BMW 7 Series – yet still attractively compact.

All the additional body length was incorporated behind the B pillars, to increase the rear seating room. To maintain the XJ's elegant visual proportions, and to gain a small but useful increase in headroom, the roofline was raised by 0.28 inches – a subtle curvature resulting excellent rear headroom. As well as the increase in headroom, the improved rear passenger space gives the XJ LWB 4.5 inches more rear knee room than offered in the SWB XJ - without compromising the XJ's excellent 16.4 cu.ft. luggage volume.

The changes were cleverly engineered – only 17 body parts (including the large side pressings, new doors and longer roof) were new to the XJ LWB, which is built on the same assembly line as the standard wheelbase model. Most significantly, it retains its exceptional shell stiffness, and thanks to careful weight management in both shell and other areas, the LWB adds only 53 lbs. body weight.

SPACE TO WORK, OR ROOM TO RELAX

The 2006 XJ Long Wheelbase is a full-size luxury sedan with an even roomier interior, and unmistakable Jaguar personality with abundant levels of 'get up and go.' It offers the additional level of rear interior space and equipment ideally suited to Jaguar's existing customer base, with even wider appeal to attract new customers.

For 2006, there is a significant rise in the level of standard equipment in all XJ models. Now, standard on all XJs are Xenon headlamps – replacing the previous halogen lights – and headlamp power wash. The long wheelbase XJ8 L also gets an electric rear sunblind as standard, while the Vanden Plas and XJR add the previously optional DVD navigation system to their long list of standard features.

In front, the long wheelbase version's seats have multi-directional power adjustment, and memory function for seat position, outside mirrors, steering column and adjustable pedals as standard, and the driving position can be fine tuned by reach and angle.

The rear seats of the 2006 XJ Long Wheelbase aren't only spacious and comfortable, they can also be a convenient place to relax or work while on the move. On Vanden Plas and Super V8 models, picnic trays fold down from the front seat backs - an ideal place to read or write, and big enough for a notebook computer, which can be powered from the auxiliary socket. The XJ also offers available multi-media connectivity for iPod, MP3 player and DVD players, digital memory media, Playstation or Gameboy systems, with the option of 6.5-inch displays in the backs of the front seat head restraints, and independent input points for two rear seat passengers.

Added space allows a variety of rear seating configurations. The layout for XJ8 L and Vanden Plas is a full width, three-passenger bench seat. The Super V8 features a three-passenger bench with four-way power adjustment for the two outer seat positions, and the front passenger seat can be moved forward from the rear seat behind it, for even more legroom. The Super V8 Portfolio offers a unique four-seat configuration with two individual power-adjusted rear seats separated by a large center console. All three seat configurations are available with a rear-controlled, four-zone climate control system (standard on Super V8 and Super V8 Portfolio).

ALUMINUM - SLIMMING DOWN

The standard wheelbase version of this seventh generation XJ sedan broke new ground when it went on sale in 2003, as a 2004 model year car. For the first time ever, the complete body structure of the XJ sedan was manufactured from aluminum alloys.

Aluminum alloy is notable for its high strength and low weight, but it isn't a new material for Jaguar. From its earliest days as a car manufacturer, Jaguar has used many forms of light alloy in its vehicles and components. In the XJ, however, Jaguar uses it in a unique and innovative way.

Unlike other aluminum-alloy-bodied cars, which typically use unstressed outer panels over a separate chassis, the XJ's body shell uses conventional, stressed skin, monocoque construction. By employing advanced assembly techniques from the aerospace industry, including adhesive bonding and self-piercing rivets, the XJ uses lightweight aluminum alloys rather than steel, as its principal body material. In effect, riveting is used in a similar way to spot welding on a steel shell, and adhesive bonding is used in a similar way to seam welding. Using both together produces immensely strong, durable joints and a lightweight bodyshell with exceptional torsional stiffness. In addition, the latest forming, casting, machining and extrusion processes have further increased the possibilities offered by both aluminum and magnesium alloys, for maximum strength with minimum weight.

With this lightweight monocoque construction, any new XJ sedan is some 180 lbs lighter than the equivalent model from the previous generation, and significantly stronger. This has a very beneficial effect on power-to-weight ratio, which is a major factor in almost all aspects of vehicle performance. Reducing a vehicle's weight (without compromising its strength) will improve its performance for the same power output. That not only improves straight-line performance and especially acceleration, but by allowing the engine to work less hard it also improves fuel consumption. Lower weight reduces the energy involved in any impact, and also improves braking performance. This benefits subjective areas such as ride comfort, handling agility and steering feel – all of which are core elements in the defining character of any Jaguar.

Other advantages are inherent in these materials and in Jaguar's unique construction method. The treated alloy panels are highly corrosion resistant, for long life, with a six-year anti-corrosion limited warranty. Jaguar uses them in such a way as to minimize repair costs in the event of accident damage. The deformable aluminum alloy front structure can withstand an impact of up to 10 mph without transferring damage to the main shell. It is bolted on, so that it can be replaced more quickly and easily if needed. Front fenders as well as trunk and hood lids are bolted on, and the doors feature 'lift-off' hinges - again for easier, more economical, replacement. The shell is also protected by injection-molded front and rear bumpers. All this helps the XJ achieve competitive insurance ratings.

THE PERSONALIZED XJ

There’s a wide array of interior trim options, and new equipment options on the 2006 XJ. There are several leather upholstery choices, including soft-grain leather, and detail finishes either with or without contrast piping, in an extended range of trim colors carefully coordinated with the range of body colors. Veneer selection includes the traditional Jaguar Burl Walnut on XJ8 L, a specialized Burl Walnut veneer with hand-inlaid Peruvian boxwood on Vanden Plas and Super V8, with a satin-finished, American Black Walnut veneer unique to the Super V8 Portfolio.

The 2006 XJ also offers versatile storage space, including a large glovebox with one-touch release offset towards the driver. As well as interior light and sunroof controls, the overhead console can incorporate the switches for features such as remote garage door opening and rear sunblind, microphones for the optional built-in hands-free telephone and JaguarVoice systems.

Jaguar is a leader in voice control technology, which can be used in the LWB to operate telephone, audio, air conditioning and satellite navigation functions, in several languages. All XJ models are pre-wired for installation of JaguarVoice and Bluetooth ® wireless technology for mobile phone (standard on Super V8 and Super V8 Portfolio).

Jaguar has embraced and developed many new technologies, but is careful to adopt them only when they are relevant and easy to use. Even without the JaguarVoice option, the XJ's DVD-based navigation system is a good example of that philosophy. It uses a large, clear, touch sensitive screen with logical menus and commands to display points of interest, restaurants, hotels, parking facilities, Jaguar dealers and gas stations – the latter automatically highlighted when the fuel level is low. Touch-screen control also extends to the major audio and climate control functions.

THE POWER TO SUPPORT THE LUXURY

For 2006, all XJ models get more power, together with the added benefit of reduced exhaust emissions. The naturally aspirated version of the 4.2-liter V8 produces 300bhp SAE (up from 294bhp) at 6,000 rev/min, again with impressive mid-range flexibility and with a torque peak of 310 lb.- ft. SAE at 4,100 rpm.

Against the clock, this engine can accelerate the XJ from standstill to 60 mph in just 6.3 seconds, while averaging 18/27 mpg city/highway. However, paired with the advanced lightweight aluminum construction, it is also an engine that provides class-leading fuel economy.

The mechanically supercharged 4.2-liter V8 uses an Eaton supercharger, twin high efficiency intercoolers, a special twin pump fuel system, and forged oil cooled pistons to handle the increased internal loads and temperatures without compromising durability. It produces a very strong 400bhp SAE (up from 390bhp) at 6,100 rpm, and a robust torque peak of 413 lb.-ft. SAE at only 3,500 rpm. What's more, its exceptional torque spread delivers at least 86 percent of the peak torque figure across a very wide range, from 2,000 rpm to well beyond the peak point. Against the clock, it delivers 0- 60 mph sprinting in just 5.0 seconds.

Both engines share similar construction, with aluminum alloy blocks and cylinder heads, designed for high strength, long durability and minimum transmitted noise and vibration. All use chain driven overhead camshafts with low noise, fine pitch, inverted tooth chains and sprockets. For 2006, supercharged as well as naturally aspirated engines use Variable Camshaft Phasing (VCP), continuously varying the phasing of the inlet camshaft according to demand, to optimize low speed torque and high speed power, while reducing emissions. High compression ratios and multi-hole injection nozzles improve combustion, improving fuel economy and further reducing emissions. Short engine and catalyst warm up times make further gains.

The XJ continues to offer the choice of powerful, refined and efficient V8 engines both matched to the advanced ZF six-speed automatic transmission that was the world's first stepped six-speed automatic transmission when it made its debut in the S-TYPE in 2002. This light, compact unit is perfectly matched to the V8 family's power characteristics, and is also a major contributor to the XJ's refinement. It features Bosch Mechatronic shift – an electro-hydraulic shift mechanism incorporated into the main gearbox casing and whose adaptive shift strategy (controlled by the ECU) responds both to road conditions and to the way the car is being driven – to give the smoothest shifts and optimum performance. It also uses the latest version of Jaguar's 'J Gate' selector, for smooth shift action.

With only a minimal weight increase for the long wheelbase XJs over the standard wheelbase XJs, all derivatives have virtually unchanged levels of performance. Engine recalibrations also see the naturally aspirated AJ-V8 move from its previous LEV2 low-emissions rating to ultra low emissions ULEV, while the supercharged AJ-V8, which gets variable cam phasing for 2006, improves from LEV to LEV2 classification.

DRIVING DYNAMICS - STILL THE XJ WAY

For the 2006 model year, all XJs feature a new braking system designed by Teves. The Teves system is designed to give improved performance and pedal feel with more initial ‘bite’.

On all naturally aspirated XJs – the XJ8, XJ8 L and Vanden Plas – the diameter of the front rotors increases from 12.6 inches to 12.8 inches, while the rear rotors increase in diameter from 11.3 inches to 11.8 inches. On supercharged models, a new Conti-Teves R Performance system is incorporated featuring new ventilated 14.0-inch front rotors and12.8-inch rears. The previous cast aluminum calipers have also been switched to an aluminum/cast iron composite to give improved caliper stiffness and deliver even better high-speed braking performance.

All XJ models still feature four-channel Anti-Locking Brakes (ABS) and Emergency Brake Assist (EBA), which contribute to the Traction Control and Dynamic Stability Control (DSC) systems. Traction Control combines engine torque control, to reduce engine torque, and selective rear wheel braking using the ABS system, to counteract wheelspin when too much power is applied on a low grip surface. DSC uses engine torque control plus selective braking on all four wheels to counteract either understeer or oversteer if the limits of adhesion are overstepped.

The combination of Jaguar's industry-leading Computer Active Technology Suspension (CATS) and the double wishbone layout and air springs ensures the classic Jaguar balance of agile handling, outstanding ride comfort and fine steering feel. CATS is an electronic control system that operates by continuously adjusting the damping characteristics to suit the driving conditions – optimizing both ride and handling. These adjustments are seamlessly made by the electronic control unit (ECU) which receives input from a series of sensors.

Both front and rear suspensions are mounted on isolated subframes, with rubber and hydraulic bushes to give precise control with maximum noise and vibration suppression. Pressurized air springs are used rather than conventional steel coils to give ample travel while optimizing the balance between comfort and control. Effective spring stiffness increases with load, to give a consistent ride, and ride height is automatically controlled according to the data supplied by three height sensors. At high cruising speeds, ride height is automatically lowered by 0.6 inches to enhance stability, minimize aerodynamic drag and maximize fuel economy.

Dynamically, the XJ long wheelbase is uniquely distinguishable from the standard wheelbase car. While gaining interior space it remains compact enough to fit into an average-sized garage, and to handle the tight spaces of multi-level parking structures. Its turning circle is a tight 39.5 feet that out-maneuvers the competition. Even with the additional five inches, the aluminum alloy monocoque shell retains its exceptional stiffness and light weight allowing the long wheelbase models to have the same highly-acclaimed ride, handling balance and steering feel as the standard wheelbase model.

SAFETY

The target in developing the aluminum-intensive XJ was to produce one of the world’s safest cars.

Building on the solid active safety foundations of excellent handling, road-holding, braking and stability, the XJ is equipped with Jaguar's Adaptive Restraint Technology System (A.R.T.S.). This system employs the world's most comprehensive and sophisticated sensing technologies to monitor the position of the front passenger, while other sensors detect the passenger's weight, the position of the driver in relation to the steering wheel and the usage - or not - of safety belts. A.R.T.S. has the capability to sense the severity of a collision and deploy the vehicle's passive safety system.

All 2006 XJs are also equipped with an advanced tire pressure monitoring system to enhance vehicle safety, and provide extra peace of mind for driver and passengers. Unlike some other systems, which use a car’s anti-lock brake sensors to detect drops in tire pressure, Jaguar’s system uses radio frequency transmitters. This allows each tire – including the spare – to be accurately and precisely monitored. And, unlike the ABS-based systems, it can detect if all four tires lose pressure gradually. If the pressure in any of the five tires drops by 25 per cent of the recommended threshold, a warning light on the instrument cluster flashes.

The new laminated side glass on the 2006 XJs aids in safety as well as reduces interior noise levels even further. Featuring two layers of laminated glass separated by an ultra-thin acoustic interlayer, the laminated side glass makes ‘smash and grab’ thefts more difficult. The plastic interlay between the glass also reduces harmful UV rays, which can deteriorate interior trim.

Earlier this year, Bluetooth ® wireless technology for mobile phones became available on all Jaguars, including the XJ. With the optional Bluetooth ® wireless module installed, an owner’s compatible Bluetooth ® capable cell phone automatically links with the car’s system, allowing safe, easy, hands-free cell phone operation.

THE XJ'S LONG WHEELBASE HERITAGE

There have been long wheelbase versions of many XJ models all through its life, starting with a stretched version of the original XJ, in 1972. The Series 2 arrived in 1973 with long wheelbase versions right from the start of production and this became the standard car in 1974 when the original shorter wheelbase models were discontinued.

Although there was no long wheelbase version of the Series 3, a long wheelbase version was re-introduced to the XJ40 range in 1993. In more recent years the numbers of long wheelbase cars have been increasing, with the XJ8 reaching nearly 40,000 sales between 1997 and the end of production in 2002.

BUILDING THE XJ

Beginning July 2006, all XJs will be built on the same assembly line at Jaguar’s Castle Bromwich plant in Coventry, England. Aluminum bodies for the XJ are assembled at the plant’s dedicated press facility and body assembly plant.

Previously, final assembly of the XJ took place at Jaguar’s Brown’s Lane plant, which involved bodyshells being shipped 15 miles by road. With the closure of Brown’s Lane, all XJ assembly is now centered at the Castle Bromwich plant, considerably improving efficiency.

The Jaguar XJ bodyshop facility makes extensive use of state-of-the-art automation. Eighty-eight robots apply structural adhesives and install the self-piercing rivets in the vehicle structure. Following the application of every 30 th rivet, the gun is tested for accuracy.

The production of the new XJ required a new, dedicated aluminum pressing facility at Castle Bromwich. Designed, engineered and constructed by Jaguar Cars, the 103,000- sq. ft. pressing plant is operated and managed by a technical partner consortium, Polynorm Stadco, under a long-term operating contract.

The XJ assembly facility was designed simultaneously with the engineering of the new XJ itself. This gave manufacturing engineers the opportunity to configure an assembly plant before anything was actually built, so that the XJ’s entire body shop existed on computer prior to its installation. Every step of the production process, down to each movement of an individual robot, was modeled in this fashion.

The body assembly operation at Castle Bromwich is surprisingly clean and quiet. Gone are the sights and sounds, sparks and residue of a spot-welding process. Decibel levels have been significantly reduced throughout the assembly hall.

JAGUAR XJ LWB TAKEN TO NEW HEIGHTS

In April 2004, Jaguar presented the dynamic long wheelbase version of the XJ luxury sedan at the New York International Auto Show. Alongside it, Jaguar also unveiled the XJ LWB-inspired Concept Eight, a stunning show car that introduced new levels of luxury and several exciting styling cues.

Less than 12 months later, driven by the enthusiastic reaction to the show car, Jaguar arrived at the 2005 New York International Auto Show with the Super V8 Portfolio, a 400bhp production car inspired by the Concept Eight design study. Spectacularly defined by its muscular looks, powerful, modern character and unique interior and equipment features, the Super V8 Portfolio is the pinnacle of the Jaguar product range.

The Super V8 Portfolio underlines the acclaimed quality of the XJ’s engineering, rooted in its advanced aluminum construction. It builds on the XJ Long Wheelbase’s light weight, strong dynamic performance, agile, sporty handling and exceptional spaciousness. It demonstrates Jaguar’s commitment to intelligent and uncomplicated use of technology. It shows, too, that there’s more to the XJ’s core character than space, elegance and luxury, and that Jaguar knows how contemporary British design can match XJ’s heritage with 21 st-century modish appeal.

The Super V8 Portfolio also amply demonstrates Jaguar’s ability to respond positively and rapidly to market and media feedback, in moving from concept to production readiness within a year of the original unveil.

The Super V8 Portfolio will be built as a limited edition car, mainly for the US and Canada , but also for other key markets worldwide. Every car will be built to a single specification. Visually, the look is distinguished by key design details including the sculpted aluminum power vents in the front wings; the distinctive mesh grille - a feature of all 2006 Jaguar sedans; its polished 20-inch alloy wheels; and two new exterior colors - either the stunning 'Black Cherry' metallic paint that first appeared on the Concept Eight show car, or an alternative new metallic finish named 'Winter Gold'.

Inside, the Super V8 Portfolio is just as different. Again closely based on the Concept Eight's design cues, it features leather and wood trim but with a very modern spin; individual power-adjustable rear seats separated by a large center console; and a new-generation equipment list ranging from Bluetooth ® wireless technology for mobile phone to a DVD system with twin rear display-screens, and from four-zone air conditioning to Alpine Dolby Pro Logic ® II surround-sound audio.

Mechanically, the Super V8 Portfolio has the power and refinement of Jaguar’s supercharged 4.2-liter AJ-V8 engine but for the 2006 model year, Jaguar's most powerful engine enjoys a 10bhp increase from 390bhp to 400bhp (SAE). An advanced six-speed ZF automatic transmission takes drive to the rear wheels. Performance is proven with a 0-60 mph time of just 5.0 seconds, proving the Super V8 Portfolio’s sporty character is more than cosmetic.

The Super V8 Portfolio builds on and challenges the XJ Long Wheelbase’s classic image, giving the car a 21 st-century attitude that makes it a new and very special addition to the XJ range.

NEW LOOKS, TOTALLY NEW CHARACTER

The Super V8 Portfolio’s most obvious feature is its dramatically different appearance. The whole impression is of a car that sits lower and wider, and is much more overtly exclusive than the standard XJ. The prominent, sculpted aluminum power vents in its front wings immediately set the Super V8 Portfolio apart from any other XJ. As do the 20-inch ‘Callisto’ alloy wheels, which feature the same highly polished five-spoke design as the 21-inch wheels of the Concept Eight, but promise better everyday durability and ride comfort for the production car.

Like the Concept Eight wheels, the ‘Callisto’ rims have slim, elegantly curved spokes, and they feature the classic Jaguar script center badge style – combining heritage with an ultra-modern spin. And, like all 2006 Jaguar sedans, the Super V8 Portfolio uses a classically simple chrome mesh grille above a deep front air intake.

At the rear of the car, the Super V8 Portfolio is further distinguished from other XJ models by large, polished twin exhaust finishers, and by ‘Super V8 Portfolio’ badging – ‘Super V8’ on the left-hand side of the boot lid and ‘Portfolio’ on the right-hand side.

Where the Concept Eight study used a full-length fixed glass roof panel, the Super V8 Portfolio has a more conventional roof with an electrically powered tinted glass sunroof – allowing the Super V8 Portfolio to retain the side-curtain airbags, deleted from the Concept Eight, and Jaguar's unique, ultrasonic-sensing Adaptive Restraints Technology System (A.R.T.S.).

The final, unique and dramatic exterior design is the Super V8 Portfolio’s standard color: a metallic Black Cherry, which is a combination of a rich cherry and deep black that shows subtle variations of both colors under changing light conditions. The new ‘Winter Gold’ metallic finish also similarly enhances the Super V8 Portfolio’s muscular silhouette.

THE INSIDE STORY – ALL CHANGE

As with the exterior, the Super V8 Portfolio’s interior treatment is even more contemporary and elegant, overlaying familiar XJ values of comfort and luxury with a modern spin, making extensive but carefully considered use of intelligent technology to serve both driver and passengers.

The Super V8 Portfolio delivers space and luxury with an added level of sportiness and modern design cues. Like any XJ Long Wheelbase, it has front and rear leg- and headroom comparable with the best in class, and it offers its own rear seat configuration, with two deep individual seats separated by a large, multi-functional center console.

Each rear seat is individually power adjustable with its own controls in the rear console, which also incorporates a range of roomy storage spaces. For maximum comfort, the rear of the center console also incorporates the individual controls for the rear seat passengers’ part of the four-zone climate control system.

All four seating surfaces are upholstered in a unique, soft-grained, ruched, Conker-colored leather, toning with the Conker color of the deep carpets and lambswool rugs. The head-lining, visors and all the internal pillars from the tops of the doors down are finished in a rich, suede-like material, and the polished aluminum sill finishers each carry the ‘Portfolio’ logo. There is also an electrically operated rear sunblind and manually operated rear-door sunblinds.

As is traditional, the Super V8 Portfolio uses wood trim across the dashboard and for the door cappings, produced with typical Jaguar quality and craftsmanship but with a distinctive twist – an elegant American black walnut veneer with a soft satin finish very much like the contemporary designer furniture that inspired it. This contrasts subtly with the Conker color of the leather, carpets and general trim, and is given a sportier attitude by touches such as the aluminum J-gate gearshift surround and the gearshift knob also finished in Conker-colored leather.

The audio system has an impressive specification compared with any other car. Produced for the Super V8 Portfolio by Alpine, it is substantially upgraded from the high-level systems already offered in the XJ Long Wheelbase. It has Dolby Pro Logic ® II sound processing, with seven amplified channels plus a sub-woofer. The latest amplifier and speaker technologies take sound reproduction quality and overall output to new heights. There are new, upgraded door speakers, a unique ‘center-fill’ speaker in the front instrument panel, two additional surround speakers mounted in the rear parcel shelf, and an additional amplifier for the front mid-bass range, which gives a 2x40-watt power increase over the standard Premium ICE system found in the Super V8.

In addition, the Super V8 Portfolio has a DVD-based entertainment system for the rear seat passengers, with individual display screens in the back of each front-seat head restraint. For ultimate convenience, the Super V8 Portfolio also includes Bluetooth ® wireless telephone connectivity, offering a high degree of integration with a variety of cell phone models controllable from the steering wheel, navigation touch-screen, and an available voice-activation module.

DYNAMIC BRILLIANCE – THE PART THAT DOESN’T CHANGE

While the Super V8 Portfolio changes dramatically in styling, interior design and equipment detail from the XJ Long Wheelbase, what doesn’t change is the outstanding technical specification. And, that includes everything from the XJ’s industry-leading aluminum monocoque construction to its powerful and supremely refined supercharged V8 powertrain.

With that starting point, the XJ sedan, in either wheelbase option, is over 400 pounds lighter than the equivalent model from the previous, steel-shelled generation. The XJ is by far the lightest car in the premium large saloon segment, and offers consequently huge benefits in performance, safety, economy and emissions performance. This type of construction also offers exceptional corrosion resistance, enhanced repair ability following minor impacts, and the associated benefits in lower insurance ratings that it brings.

In one area, the Super V8 Portfolio actually exceeds the Concept Eight’s specification, with a power output of 400bhp (SAE) compared to the design study’s 390bhp (SAE). In the Super V8 Portfolio is powered with Jaguar’s now familiar and highly regarded supercharged 4.2-liter V8 engine, which has a hugely flexible 399 lb.-ft. of torque at only 3,500 rpm – with at least 86 per cent of the peak torque figure produced across a wide range from only 2,000 rpm to well beyond the peak torque point.

This excellent engine is matched by the superb six-speed automatic transmission already used in the XJ Long Wheelbase. Like the engine, it is notably light and compact, and features an electro-hydraulic shift mechanism whose adaptive shift strategy – controlled by the engine management – responds to both road conditions and the way the car is being driven, to give the smoothest shifts with optimum performance.

The Super V8 Portfolio retains all the XJ Long Wheelbase’s agile driving dynamics and class-leading ride comfort. Both front and rear suspension use what are essentially double wishbone layouts, with lightweight alloy components to reduce unsprung weight, benefiting of both comfort and control. Like other XJ Long Wheelbase models, the Super V8 Portfolio uses air suspension, and Jaguar’s Computer Active Technology Suspension (CATS) system. This electronic control system continuously adjusts the XJ’s damping characteristics, from firm to soft in milliseconds, to suit the driving conditions, optimizing both ride and handling.

The Super V8 Portfolio uses the supercharged XJ Long Wheelbase’s new Conti-Teves high performance brake system enhanced by four-channel ABS anti-lock brakes and Emergency Brake Assist (EBA). Electronic Traction Control and Dynamic Stability Control (DSC) are also standard.

Like other XJs, the Super V8 Portfolio features Jaguar’s industry leading Adaptive Restraint Technology System, A.R.T.S., combining dual-stage front airbags, ultrasonic front passenger sensing, an energy absorbing seating system incorporating an anti-whiplash mechanism in the front seats, and pyrotechnic pre-tensioners for all safety belts. Safety equipment also includes side-impact chest airbags in the driver and front passenger seat bolsters, side air curtains over front and rear doors, and LATCH rear child-seat attachment points.
