Jaguar XF

Jaguar created the XF, a model that combines style and performance of a sports car in a very refine way. The XF will be available from launch with a range of four engines, all sending the power to the wheels through a six-speed automatic transmission. The first one is a 2.7-liter V6 twin-turbocharged diesel that is able to accelerate from 0 to 60 mph in 7.7 seconds and can reach a top speed of 143 mph. The next on the list is the 3.0-liter V6 petrol that can run from 0 to 60 mph in 6.2 seconds and can accelerate reaching a top speed of 148 mph. The third variant is the 4.2-liter V8 petrol that can do the 0-60 mph in 6.2 seconds and can reach a top speed of 1555 mph. Last, but not least, is the 4.2 s/c V8 petrol that can sprint to 60 mph in 5.1 seconds and can reach an electronically speed limit of 155 mph.

Challenging convention and setting its own rules, the new Jaguar XF fuses the style and performance of a sports car with the refinement, space and sophistication of a luxury saloon. This is the beginning of a new era for Jaguar.

The new XF: a dramatic expression of a bold new Jaguar design language, with a driving experience that exceeds expectations created by the striking appearance: relaxed and confident, with outstanding ability and control.

Resolutely true to the Jaguar philosophy of creating Beautiful, Fast cars, the XF goes further, adding a new dimension to the marque. The four-door XF has the visual excitement of a coupe, but room inside for five adults to enjoy an interior wholly contemporary in style yet uniquely Jaguar.

As well as space, the new XF`s interior ambience is enriched by crafted, luxurious materials, sophisticated instruments and calm interior mood lighting. Engineering excellence and attention to detail mean the XF`s interior matches the best-in-class for refinement, while Jaguar`s intelligent use of technology and driver-friendly Touch-screen controls add new layers of comfort and ease of use.

Every XF model has shift-by-wire transmission control, with Jaguar`s class-leading sequential shift system " its popularity already confirmed by feedback from XK sports car customers " used for the first time in a saloon. Shift-by-wire replaces manual shift linkages with electronic commands and gives every XF rapid and very smooth gearshifts " faster, even, than the acclaimed XK`s transmission.

The Jaguar Sequential ShiftTM System gives the driver the option of one-touch manual gearchange control via steering-wheel mounted paddles. There are also multiple JaguarDrive ControlTM transmission modes, including Dynamic and Winter settings, which interact with throttle progression, Dynamic Stability Control thresholds and shift strategy to match mood and conditions.

But the most exciting feature of the XF`s transmission control is the all-new JaguarDrive SelectorTM " an industry-first rotary shift interface that combines precise, intuitive control with space-saving packaging, to allow maximisation of interior storage options.

Other innovative functional features add more `surprise and delight`. Air-conditioning vents present a flush dashboard surface until the ignition is switched on, at which point they elegantly rotate to the open position. Another new technology - JaguarSenseTM - introduces touch or proximity-sensing control for overhead console lights and the glovebox release.

Every level of audio system features at least eight speakers, with a premium system designed in association with highly respected audio specialist Bowers & Wilkins available on range-topping models. Radio options now include a Digital Audio Broadcasting (DAB) system and Sirius Satellite Radio for the North American market, while the XF technology count includes Bluetooth® communications technology, plus optional iPod® and MP3 player connectivity with full-function control through the Touch-screen " and an auxiliary port on every car for other portable audio devices.

Other available features include JaguarVoiceTM control to operate audio and telephone functions, Blind Spot Monitor, Front and Rear Parking Aids and Rear Camera Parking Aid, Adaptive Cruise Control, Automatic Speed Limiter, Tyre Pressure Monitoring System and Electronic Parking Brake.

Mick Mohan, XF Chief Programme Engineer comments:

"The interior of the XF is a combination of style and substance. It bristles with innovative, industry-leading features. From the smart technical solution of the JaguarDrive SelectorTM, through the seamless efficiency of rotating vents, to the simplicity of Touch-screen control, the XF proves aesthetics and function can work together in perfect harmony."

Engineering excellence and class-leading structural rigidity are at the heart of the new XF`s construction. The advanced body structure, which comprises high-tech materials and new-generation design techniques, maximises strength and minimises weight to give the XF superb performance, refinement and efficiency across its range of V6 and V8 engines. These engines include the quietest diesel engine in its class and a supercharged V8 that delivers outstanding levels of performance.

The new XF is best in class for torsional stiffness, and with a wide rear track displays excellent handling characteristics. These elements underpin a dynamic ethos that is driver-focussed yet supremely comfortable and refined. Just as its looks promise, the new XF excels across the board, in every role from a sports car to a luxurious long-distance cruiser.


AT A GLANCE

" The XF is a four-door Jaguar that fuses the style and performance of a sports car with the refinement, space and sophistication of a luxury saloon.

" The exterior styling of the XF is the first expression of Jaguar`s new design language in a saloon car. With interior design that is the equal of the exterior in terms of crafted execution and visual excitement, the XF offers a truly contemporary, luxury environment.

" The coupe-like lines of the XF belie the amount of space inside: there is room for five adults in comfort, generous interior stowage and a boot capacity of up to 540 litres* (plus the opportunity to fold the rear seats and add a further 420 litres).

" Jaguar craftsmanship adopts a sharp new edge on the XF. Sophisticated instrumentation, a Touch-screen, modern materials and graphics complement new `surprise and delight` features. On entry to the XF, the start button pulses red, like a heartbeat. Start the engine and the JaguarDrive SelectorTM rises into the palm of the hand, while rotating vents turn from their flush, `parked` position to their functional open position.

" The best torsional stiffness in class delivers both refinement and dynamic performance " underpinning the driver-focussed yet remarkably comfortable driving experience.

" The XF will be available from launch with a range of four engines,** all featuring Jaguar`s proven six-speed automatic transmission with steering wheel-mounted `paddles` for manual gear selection (Jaguar Sequential ShiftTM):
- 2.7-litre V6 twin-turbocharged diesel: 0-60mph in just 7.7 secs (0-100kph in 8.2 secs) and a top speed of 143 mph;
- 3.0-litre V6 petrol: 0-60mph in 7.9 secs (0-100kph in 8.3 secs) and a top speed of 148mph;
- 4.2 n/a V8 petrol: 0-60mph in 6.2 secs (0-100kph in 6.5 secs) and a top speed electronically limited to 155mph;
- 4.2 s/c V8 petrol: 0-60mph in 5.1 secs (0-100kph in 5.4 secs) and a top speed electronically limited to 155mph.

" Key driving aids on the XF include Electronic Brake Assist, Electronic Brakeforce Distribution, Anti-lock Braking System, Dynamic Stability Control, Cornering Brake Control, and Engine Drag Torque Control. And, for the first time in a Jaguar, Understeer Control Logic which decelerates the car and helps to restore grip to the front wheels when required.

" The new XF has a wide portfolio of driver assistance features including a Blind Spot Monitor, Front and Rear Parking Aids, Rear Camera Parking Aid, Adaptive Cruise Control, Automatic Speed Limiter and Tyre Pressure Monitoring System. Bluetooth® compatibility, iPod®/MP3 player interfaces, JaguarVoiceTM, Digital radio and a single or six-disc CD player ensure owners can listen and talk as they choose.

" XF offers three levels of audio system, all controlled through the Touch-screen. The top-of-the-range Bowers & Wilkins 440w Premium Sound System option offers extraordinary clarity and faithful sound reproduction. Designed and tuned for the XF by Bowers & Wilkins, the surround-sound system delivers a powerful and vivid performance.

" In a first for a Jaguar saloon, the XF has the marque`s new Pedestrian Contact Sensing System. This can mitigate pedestrian injury by firing actuators that deploy the bonnet, resulting in a cushioned space between the bonnet and engine hardpoints.

" Three trim levels will be offered, depending on market. The Luxury level will be available with either petrol or diesel V6 engines (and naturally aspirated V8 models in the US), Premium Luxury (with petrol or diesel V6, or naturally aspirated V8), and SV8 (with the supercharged V8 petrol).

" The XF is available to order now, depending on market. The first cars will be delivered to customers in March 2008. Pricing is available from individual markets depending on the start of customer orders.

AERODYNAMICS

As well as facilitating packaging excellence, the XF`s new design language has another significant functional advantage: for the first time on any Jaguar, the entire body was developed using Computational Fluid Dynamics (CFD) before the car ever saw a wind tunnel. Every area from the outer skin to the lightweight, composite undertray to the cooling airflow (even the shape of the exterior mirrors) was optimised using this process. The higher, squarer tail is more efficient aerodynamically than a lower, rounded one, and the XF`s coupe-like roofline and subtle, raised bootlid lip improve airflow over the rear of the car. As a result, the XF has the best aerodynamic performance, in terms of drag, of any production Jaguar ever and is better than the race-bred, limited edition XJ220 supercar.

The XF`s drag coefficient is just 0.29 and the front-to-rear lift balance is precisely zero. This aerodynamic performance contributes to impressively low wind noise, aids fuel consumption and strong high-speed stability and, of course, is vital in ensuring ideal handling balance through optimising drag and lift forces.


ENGINEERING

Underlying the new visual design language, the XF is the product of a new generation of design technology, materials and manufacturing opportunities, as Phil Hodgkinson, Jaguar Programmes Director, explains:

"The engineering disciplines behind the XF are as ground-breaking as its new design language. New development processes and computer tools allowed us to work through the programme at a quicker pace than anything previously; new technologies and materials combine strength with lightness; and Jaguar craftsmanship, too, has explored new, exciting contemporary avenues."

Virtual Process (VP) and Virtual Series (VS) are the cutting-edge technologies used by Jaguar to take the XF from concept to reality. These techniques use massive computing power and sophisticated modelling programmes to create components and even whole vehicles in the virtual world, before building physical parts and perfecting the systems and processes to manufacture the car. The XF represents the first time that VP and VS tools have been used by Jaguar throughout a complete vehicle programme - from vehicle development, to production feasibility studies, to build planning.

But VP also dramatically improves overall quality, by allowing rapid sign-off of component designs, and eliminating the early physical prototype stage. With VP, when prototypes finally are built, they are intended only to validate what is already known, not to develop areas that are still unresolved. Fully representative vehicles are used for physical evaluation, including on-road testing, crash-testing, hot and cold climate testing, and durability testing. At the same time, the VS programme is working on everything that is needed eventually to build the car " leading to significant improvements in craftsmanship, efficiency, even long-term serviceability.

New technology is also key to the XF`s construction. It was the first programme within Jaguar to use the next-generation CAD programme C3PMG, which combines an all-new CAD-modelling software package with an all-new data-management package " opening the way to exceptional strength without unwanted weight. The design is led by safety needs, especially by the latest side intrusion and SUV over-ride requirements. The reinforced passenger safety cell incorporates new thinking from the lower side rails up.

The XF adopts the latest generation steels, especially in the upper body " including high carbon steels, dual-phase, hot-formed boron steels, and bake-hardened steels to form a vertical safety `ring` around the occupant cell. As well as combining strength with lightness, these steels improve corrosion resistance, by making best use of zinc and improving e-coat paint flow " and new thinking means that in spite of their strength, the XF`s A and B-pillars are impressively slim, to the benefit of both visibility and accessibility. Similarly, the lower sills are the first component on any Jaguar to use incredibly strong, dual-phase DP600 steel.

Second-generation Pedestrian Contact Sensing System " the acclaimed safety system introduced by Jaguar on the XK " is included on the XF (market dependent). This can mitigate pedestrian injury by firing actuators that deploy the bonnet, resulting in a cushioned space between the bonnet and engine hardpoints. The system builds on the technology proven in the XK, using higher resolution sensing and an active rear-hinged bonnet.

Every XF also comes with two-stage driver and front passenger airbags, side and curtain airbags and seat occupant sensing systems to help ensure the airbags work precisely and only as needed in every circumstance. Front-seat occupants also have the added protection of an anti-whiplash system and `soft-landing` technology in the seat-belt retractors to soften contact with the front airbags.

Other changes - many of them made possible by extensive use of the Virtual Process during the development programme - improve craftsmanship by optimising the manufacturing process. Close attention to optical quality creates the smallest, most consistent panel gaps and other new measures improve resistance to minor impacts, making accident repairs easier and less expensive, so contributing to significant cost-of-ownership benefits.


BRAKES

The XF uses large 326mm x 20mm vented front discs on all naturally aspirated models and 355mm x 32mm vented front discs on the SV8 model for powerful, balanced braking performance. The rear discs on all versions measure 326mm x 20mm.

An extremely stiff pedal box contributes to a particularly solid pedal feel, and the brake assistance is tuned to give a very progressive feel, while softening the initial response.

The XF uses Jaguar`s Electric Parking Brake, with a small and neat, chromed release in the centre console. As the XF`s braking system communicates electronically with the shift-by-wire technology of the JaguarDrive SelectorTM function, so the Parking Brake is released automatically as Drive is selected " although the Parking Brake can also be engaged and disengaged manually if appropriate.


STEERING

Variable ratio power-assisted steering is standard on every version of XF, for reduced parking effort at low speeds and greater precision and feedback at higher speeds - and especially for positive weight to the on-centre feel, which is part of the new dynamic flavour. Steering effort at manoeuvring speeds is also reduced on diesel models.

The new XF adopts an electronic steering column lock - for compatibility with passive entry mode and the Jaguar Smart Key SystemTM. There is no longer a key barrel on the column, however the electronic lock satisfies Thatcham security legislation for the UK market.

The XF`s steering wheel includes cruise-control, JaguarVoiceTM (where fitted) and audio controls - including volume, and radio channel pre-sets. The source button toggles through AM/FM/CD, plus any external device functions. The select buttons allow features such as CD track change, radio channel pre-set selection or iPod® or MP3 track change if such a device is in use.

WHEELS AND TYRES

Depending on market and model, the XF is available with 17, 18, 19 or 20-inch wheels; the SV8 being the only car in its class to have 20-inch wheels as standard. All are cast in aluminium alloy and every design combines maximum strength with minimum weight. To satisfy Thatcham security stipulations, there are also 20 variations of anti-theft locking nut. All cars for the majority of markets carry the same specification of 18-inch diameter alloy mini-spare.

For major European markets, cars with 17 and 18-inch wheels are fitted with the Jaguar Tyre Repair System as a space and weight-saving alternative to the `mini-spare`. This replaces the spare wheel, jack and tool kit, and can effect a temporary repair of any puncture of up to 6mm diameter in the tread area - sealing the hole and re-inflating the tyre to enable the car to be driven to where a permanent repair or replacement can be carried out. When fitted in lieu of a spare wheel, the Jaguar Tyre Repair System liberates an additional 40 litres of stowage space under the boot floor.

DRIVER AIDS

The XF`s main control module governs many key safety functions including Emergency Brake Assist (EBA), Electronic Brakeforce Distribution (EBD), Anti-lock Braking System (ABS), Traction Control through engine and brake intervention, Dynamic Stability Control (DSC), Cornering Brake Control (CBC) and Engine Drag Torque Control. And for the first time, the XF adds Understeer Control Logic, which has been designed to mitigate understeer by intervening through the engine management and braking systems to decelerate the car and help restore grip to the front wheels.

A two-stage DSC system similar to that featured on the new XK is standard. It combines the normal on-off switchable DSC function, which reacts as soon as it detects slip, with Trac DSC, which allows more slip before intervening " better for a more sporting driving experience. It also allows a degree of wheel overspin on deep soft surfaces, which is essential for running with snow chains. The system defaults to normal `DSC on` with each ignition-on sequence.

In Dynamic Mode (SV8 only), pressing and holding the DSC button fully disables the system, allowing an experienced driver to exploit fully the capability of the chassis, where conditions allow. Mode selection is confirmed on the instrument cluster display.

Also new on XFs fitted with Adaptive Cruise Control (ACC) is Electronic Brake Prefill. This senses any rapid throttle lift-off and initiates a small brake hydraulic pressure build-up in anticipation of the brakes being applied, to give better pedal response and slightly shorter stopping distances.

JaguarDrive ControlTM offers different modes that interact with the DSC system, engine and gearbox, to change the characteristics of engine mapping, transmission shifts and brake interventions depending on driving conditions and circumstances. On naturally aspirated cars JaguarDrive ControlTM has Normal and Winter modes, on the SV8 model there are Normal, Winter and Dynamic modes - the last of these to allow a more purposeful driving style.


DRIVING DYNAMICS

Delivering the highest levels of driver enjoyment is a must for any Jaguar, so it is essential that the XF`s driving dynamics live up to its powerfully athletic looks. Underpinned by the stiff platform, wide track and finely resolved suspension, steering and brakes, the XF`s dynamic flavour combines the comfort and refinement of a luxury saloon with the grip, balance, responses and stability of a sports car. The result is a dynamic character that delivers real driver involvement, as far removed from the premium saloon crowd as are the XF`s bold looks.

Chief Engineer, Vehicle Integrity Mike Cross explains the development processes behind the new car:

"Two key objectives defined the XF`s dynamic flavour " firstly that its driving abilities should match its sporting coupe-like looks, and secondly that it should have Jaguar`s unique balance of ride, handling and refinement. The XF succeeds on all counts and the result is a very special experience."

Every XF model uses Jaguar Sequential ShiftTM transmission control, allowing manual gear selections in the automatic transmission via `paddle` switches mounted on the rear of the steering wheel, in either Drive or Sport mode.

But sporty is only half the XF driving dynamics story " refinement is equally important, and equally impressive. With its stiff shell, smooth powertrains and extraordinary attention to acoustic management (including a secondary bulkhead and dual-isolated subframe on all versions), the XF has outstanding NVH performance to match the best in class. At 30mph (50kph), for instance, the interior noise level is only 65.6dB, below its nearest BMW 5-Series rival, even when the XF is on larger wheels. Special attention has been paid to the V6 diesel, whose sound quality is so impressive it is hard to tell which engine lies beneath the bonnet. The V8 XF takes lessons from the XK with an exhaust system tuned for an overtly sporty sound quality, especially when accelerating hard " again, just as the looks promise.

IN SUMMARY

The new XF is a milestone for Jaguar. In every respect it signals the future of the marque " and yet it remains true to the essence of what has always made great Jaguars the cars they are.

The new XF is more than just a strikingly beautiful Jaguar. It also appeals from a rational perspective to buyers of all ages who expect value for money, even from a luxury marque. XF pricing is extremely competitive throughout the range, in spite of rich standard feature specifications and extensive use of advanced technologies.

And XF buyers can look forward to enjoying continued fiscal benefit. Anticipated strong residual values will appeal to those using the XF as a `business` car, while the V6 diesel in particular has competitive emissions levels, with the accompanying tax advantages for company car users and fleet buyers.

As one of the most visually striking, technically sophisticated and driver-oriented saloon cars that the company has ever produced, the XF is synonymous with the forward-looking focus that now defines the Jaguar brand. Its design language is entirely new, its performance and dynamic flavour support " even eclipse - its sporting looks, and intelligent use of advanced technology and innovative control interfaces set the XF far apart from any other premium sports saloon. This is the future, now.
