THE NEW JAGUAR XF

http://www.jaguarxfmedia.com/index.jsp
INTRODUCTION
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 sedan. 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 that is 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 possesses shift-by-wire transmission control, with Jaguar’s
class-leading sequential shift system, which will be used for the first time in
a sedan. Shift-by-wire replaces manual shift linkages with electronic commands
and gives every XF rapid and very smooth gearshifts – faster than the acclaimed
XK’s transmission.
The Jaguar Sequential ShiftTM System gives the driver the option of one-touch
manual control via steering-wheel-mounted paddles. There is also the choice of
multiple transmission modes via JaguarDrive ControlTM, which matches throttle
progression, DSC thresholds and shift strategy to mood and conditions, including
Dynamic and Winter modes.
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 maximization 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 the audio system features at least eight speakers, with a premium
system designed in association with highly respected audio specialists 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, Tire
Pressure Monitoring System, Electronic Parking Brake and more.
Mick Mohan, XF Chief Programme Engineer:
“The interior of the XF is an outstanding 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, maximizes strength and
minimizes weight to give the XF superb performance, refinement and efficiency.
The new XF has exceptional torsional stiffness, and with a wide rear track it
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 sedan.
– The exterior styling of the XF is the first expression of Jaguar's new design
language in a sedan 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 trunk capacity of
17.6 cu. ft. (500 liters), plus the opportunity to fold down the rear seats and
add a further 14.8 cu. ft. (420 liters).
– 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 refinement and dynamic
performance – underpinning the driver-focussed yet remarkably comfortable
driving experience.
– The XF will be available from launch with two different engines, all featuring
Jaguar's proven six-speed automatic transmission with steering-wheel-mounted
paddles for manual gear selection (Jaguar Sequential ShiftTM):
- 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 driver 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 Tire 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 440-watt 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.
– Three trim levels will be offered in the U.S. market – Luxury, Premium Luxury
and Supercharged levels.
– 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.
THE XF IN DETAIL
DESIGN - EXTERIOR
The first defining element of the new XF as a true sporting Jaguar is its visual
strength. Driven by a bold new design language, the XF firmly emphasizes
contemporary and emotional themes while remaining unmistakably a Jaguar.
Targeting leadership in exterior and interior design, the XF builds on already
high standards of craftsmanship, quality and dynamic refinement, while improving
packaging and aerodynamics even further.
As Design Director Ian Callum explains:
“The XF is a stage in a personal journey for me. It has always been my career
goal to return Jaguar to its rightful place as leader in automotive design. Cars
like the original XJ6 left a lasting legacy and my ambition has been to create
something as seminal. The XF is that car.”
The new XF enters the Jaguar range in the niche long occupied by Jaguar’s much
loved mid-sized sedans such as the original XJ Series 1 – a car that was smaller
than today’s XJ. But unlike many D/E premium sedans, the new XF pushes
boundaries away from the ‘three box’ style and creates a four-door, five-seat
sedan with strong, coupé-like lines. Jaguar’s new design language, which debuted
with the new XK sports car, is applied to a sedan car for the first time in XF.
The visual step forward is as significant as it is obvious - the XF’s
proportions, for example, are so closely matched to those of the XK that the
screen rake angles are the same on both cars.
Having the space and practicality of full five-seat accommodation was a program
imperative, so the XF is proportioned to provide interior space and levels of
comfort that challenge for best-in-class honors. At 195.3 in. (4961mm) long and
73.9 in. (1877mm) wide, on a lengthy 114.5 in. (2909mm) wheelbase, the XF is
1.73 in. (45mm) longer and 0.98 in. (25mm) wider than its nearest 'dimensional'
competitor, the Audi A6 – with even greater advantages over the BMW 5-Series,
Lexus GS300 and Mercedes-Benz
E-Class.
The XF’s visual emphasis is sporty, muscular and dynamic – a character defined
by a sweeping silhouette inspired by the XK, a powerful grille, dramatic side
window graphics and, of course, strong Jaguar shoulders. The look, however, does
not come at the expense of efficient packaging, for the XF’s waistline rises to
meet the roof rather than the roof coming down to meet the waist – which
improves interior space. This rising waistline gives the XF a much higher tail
than any previous Jaguar, providing the twin benefits of much improved
aerodynamic performance, together with substantially increased luggage volume.
At a maximum of 17.6 cu. ft., it is the equal of anything in the class and
betters most rivals.
The XF’s Jaguar character is defined by its face – centered around a bold intake
grille which provides a focal point for the feature lines which stream back over
the bonnet and cabin. The grille’s mesh pattern is itself an important element
of external jewelry. Its woven pattern is an emotional design signature that is
quintessentially British, with strong sporting connotations.
The headlamps further emphasize the way in which Jaguar’s design language has
progressed. The one-piece clusters have a wide aspect ratio and wrap around the
corners of the body onto the front wings. Closer inspection of the headlamp
internals reveals twin round elements incorporated within their overall shape; a
subliminal reminder of the Jaguar ‘quad lamp’ signature.
The front lower bumper includes powerful air intakes, carrying chrome 'splitter'
blades whose simple, modern lines evoke the technical, strongly engineered shape
of a propeller blade.
In profile, the new XF follows the Jaguar credo of having flowing, uninterrupted
lines. The feature line that starts at the outboard edge of the lower air
intake, runs up over the front wing, rises into the waistline and then runs
around the trailing edge of the boot lid is an example of this.
The stance of the XF is completely new for a Jaguar sedan. It gives the car a
‘ready to pounce’ look that suggests latent power and energy. The strong wedge
profile of the waistline imparts a forward-biased dynamic before the car has
even turned a wheel.
The XF’s wide rear track not only enhances the handling and dynamic values of
the car but also reinforces the visual confidence of the new shape. At the rear,
the design elements integrate to emphasize the width of the car. The bright
signature blade, which proudly carries the ‘JAGUAR’ script, appears to extend
beyond the boot lid and into the tail lamps by aligning it with the clear
‘windows’ of the reverse/indicator clusters.
The tail lamp graphics wrap around onto the rear wings, leading your eye out to
the broad, muscular rear wheel arches. The lamps use state-of-the-art LED
technology to give the XF an unmistakable night-time signature and an exotic
personality. The wheels lie at the extremities of the body, with the wings
sculpted to make them look like powerful, bulging muscles. Every wheel and tire
combination has been engineered to have the same rolling radius, giving a superb
‘wheel to body’ visual relationship. The XF is fitted with 18, 19 or 20-inch
alloy wheels, the Supercharged being the only car in its class to have 20-inch
wheels as standard.
The exterior details of the XF have been designed as if they are finely crafted
items of exquisite jewelry. The distinctive bright aluminum finisher around the
side window, for example, is unusual in being a single-piece pressing and is an
unmatched piece of craftsmanship. The side power vents have the Jaguar name
embossed on an ‘ingot’ bar across the center, while the ‘venturi’ shape below
the tail – which hints at the XF’s sophisticated aerodynamics – is positioned
above large, stylized twin chrome tailpipes.
The XF is unmistakably a Jaguar and its badging unequivocally identifies it as
such: a large ‘growler’ badge is prominent on the front grille, while adding the
Jaguar ‘leaper’ to the rear boot lid is an emotional statement - a powerful
signature that customers associate strongly with the most sporting Jaguars.
From launch, the XF offers three trim levels: Luxury, Premium Luxury and
Supercharged. Externally, with the exception of wheel styles, and a badge on the
Supercharged, all cars will look the same – a customer is buying an XF, rather
than an XF in a particular trim level.
Wayne Burgess, XF Senior Manager, Jaguar Design:
“It was time for Jaguar to be bold and the XF fits that brief perfectly. With
its dramatic styling, powerful yet beautiful flowing lines and a distinctive
face, the new XF looks like no other Jaguar sedan – and yet it could only be a
Jaguar.”
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 optimized using this process. The higher, squarer tail is far more
efficient aerodynamically than a lower, rounded one, and the XF’s coupe-like
roofline and subtle, raised boot lid 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 very close to equalling 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. These aerodynamics contribute to impressively low wind noise,
aid fuel consumption and strong high-speed stability and, of course, are vital
in ensuring ideal handling balance through optimizing drag and lift forces.
DESIGN - INTERIOR
Relax inside the XF and you are in a very special place indeed. There is space –
more than many will imagine given the XF's sports sedan design – but also the
sense of being in a perfectly proportioned, agile car. There is also comfort –
of course – but it is the craftsmanship, materials and attention to detail that
impress. Consider, too, the generous equipment specification – the features that
empower rather than overpower the driver – and the strengths of the XF are
readily apparent.
The interior design maximizes the feeling of space, with driver and passenger
seating positions, the relationship of seats to window areas, and the volume and
versatility of stowage options all contributing. New thinking on seat design –
the front seats are deliberately sculpted and reduced in size (but not comfort)
– liberates space and makes access easier, too. The increased track and rear
seat width means 6’4’’ adults can sit in complete comfort. And while the XF
roofline might say ‘coupé’, the rear headroom says ‘sedan’ better than many
rivals.
Just as the XF’s exterior defines a new design direction, its interior moves
from traditional themes to contemporary, sporting luxury - emphasized by
‘surprise and delight’ features such as the JaguarDrive SelectorTM and the
rotating vents; through the use of sophisticated new materials; and by all-new
graphics and interior lighting systems.
Jaguar Cars Interior Designer Alister Whelan says the inspiration for the XF
cabin was pure, modern luxury:
“We have found exciting new ways to say ‘luxury’. The lines are clean and pure,
the materials are familiar, but with a very modern flavor - from soft-grained
leathers to real wood veneers with a bold, contemporary spin. Even the phosphor
blue interior lighting has its own mood.”
The line defined by the soft-trimmed dashboard top and aluminum finisher runs
continuously through front and rear doors, making the interior feel more
spacious, and especially making it seem wider from the front seats.
Real wood – more than in any Jaguar since the iconic MkII sedan in the 1960s –
underlines what is a luxurious interior, with veneers including Satin American
Walnut, Burl Walnut and a very modern, straight-grained Rich Oak that works
particularly well with textured aluminum highlights that are used in every XF to
enhance the contemporary, technical feel. And true to Jaguar’s core values of
authenticity of materials, what looks like wood really is wood.
Even the XF’s headlining material is a step up from conventional materials.
Using a modern technical weave known as Morzine, the entire cabin roof and
A-pillars are trimmed in this eye-catching, contemporary finish.
In the XF, many features are ‘invisible until needed’ - a different approach
from carmakers who push technology as a dominant interior theme. The rotating
vents revolve out of sight when they are not in use; the touch-screen controls
many features, allowing mechanical buttons to be reduced to a discreet panel
below the navigation screen. Jaguar design is about reducing clutter; the
switches that are there primarily give quick and easy access to functions such
as audio volume and climate control temperature.
As well as the center cubby, which includes CD storage, an auxiliary power
supply and a Portable Audio Interface for an iPod® or other MP3 player
(depending on market), the center console has two compartments with veneered
lids. It can take a 44-ounce ‘big-gulp’ cup and two more modestly sized cups
plus other oddments. Without the cupholders in place there is generous oddment
storage space for items such as sunglasses in their cases. There are large
storage pockets in each door and pockets on the backs of the front seats and the
rear center armrest also incorporates two cupholders.
But it is not only in the storage of everyday items that the XF excels – the
minimum capacity of the trunk is 17.6 cu. ft. (500 liters) with the option to
liberate a further 14.8 cu. ft. (420 liters) of space by folding down the rear
seat backs.
One feature that maximizes space efficiency is the JaguarDrive SelectorTM, an
unobtrusive yet completely practical solution to selecting an automatic gear
mode. But the Selector does much more than this thanks to a start-up sequence
that is a strong driver 'handshake' ¬and a real statement of the XF’s
individuality.
Get into an XF and the start button in front of the JaguarDrive SelectorTM
pulses red, like a heartbeat. Press this button to start the engine and the cast
alloy JaguarDrive SelectorTM raises into the palm of your hand. Simultaneously,
the navigation system initializes to its home page and the rotating vents turn
from their flush, 'parked' position to their functional open position. While the
vents are open, they offer vertical and horizontal directional vane adjustment
and full airflow adjustment down to zero.
With the JaguarDrive SelectorTM, automatic transmission functions are selected
simply by turning the control with the fingertips. As an example, Drive to Drive
Sport selection is accomplished with a simple push and turn action. Returning
from S to D, the rotary control operates with spring-assistance, which
eliminates the need to pull the Selector. It couldn’t be simpler.
Phosphor blue mood or ‘halo’ lighting echoes the ambience you might find in a
favorite contemporary bar or restaurant. This same lighting technology is also
used in MP3 players and mobile phone handsets to illuminate keypads and
controls. On the XF, halo illumination around the switch panels and JaguarDrive
SelectorTM console, the start-stop button and Electric Parking Brake gives a
soft glow that indicates their positions without distracting the driver.
Mood lighting is also incorporated into the header console, bathing the center
console in a cool blue light, while lights under the front door releases softly
illuminate the door-mounted switches.
Soft, phosphor blue illumination is also used on the instrument dials,
highlighting the sporting feel of the aluminum-colored dials. As well as being
soothing, blue does not conflict with any of the green, yellow or red alert or
warning signals on the car.
Following the luxury theme, there are chrome highlights on the column stalks and
the molded halo material around the JaguarDrive SelectorTM and audio/climate
switch-pack appears as a soft, almost smoky, chrome until illuminated.
The main switches have been designed to give the feel of a high-quality audio
system, incorporating short travel with positive feedback to the user. This
design is then used in the minor switchpacks in the overhead console and the
auxiliary pack outboard of the steering wheel.
Electric window switches are illuminated through a jewel-like design that
diffuses a soft phosphor blue glow around the switch. All switches and buttons
have the same Tungsten finish to emphasize harmony and sophistication in the
interior.
To say that luxury comes as standard on the XF is almost an understatement.
Front seats are electrically adjustable, with a minimum of eight-way seat
adjustment for the driver and front passenger, while the Supercharged offers
16-way driver’s seat and 12-way passenger’s seat adjustment with 4-way power
lumbar and cushion length adjustment for the driver. The new XF also introduces
the option of active heated and cooled ventilated front seats, with fan-assisted
whole seat heating, whole seat cooling, or just squab heating or cooling. And
because the XF cleverly separates seat and cabin temperature controls, it gives
the option of a warm cabin with a cool seat, or vice versa. And all of this with
a new climate control system that is also the most efficient Jaguar has ever
offered.
Attention to detail was a mantra through the XF’s development. The three trim
levels offer combinations of bond-grain leather and soft-grain leather in a
subtle color palette. The Luxury trim level uses non-perforated bond-grain
leather for the seat facings with matching material for the twin needle stitched
fascia and door top rolls. Premium Luxury and Supercharged have a sumptuous
interior with soft-grain leather used throughout for seats, fascia and door top
rolls, while perforated soft-grain leather is used on the seat facings to
facilitate the fan-assisted heating/cooling feature.
The XF is exceptionally well equipped. Bluetooth® technology allows mobile
handsets with Bluetooth® capability to communicate with the car’s in-built
telephone system and phone calls can be controlled either via the touch-screen
or hands free, using the steering wheel controls or JaguarVoiceTM control.
The XF offers three levels of audio system, again all controlled through the
touch-screen. The eight-speaker Jaguar Sound System has a woofer and tweeter
unit in each door – the woofer being mounted much higher than conventional
systems to ensure good bass reproduction. The Jaguar 320-watt Premium Sound
System has a DSP amplifier linked to nine speakers: eight premium door-mounted
and (through clever packaging of the trunk area) a 32-liter sub-woofer for
enhanced bass. The Bowers & Wilkins 440-watt Surround Sound System has a remote
amplifier with Dolby® Pro-Logic® II 7.1 Surround Sound and 14 speakers. Bowers &
Wilkins technology, exclusively used in Jaguar cars, is acclaimed by
audiophiles, artists and recording engineers alike. Kevlar cones in the larger
speakers (the distinctive yellow appearance is discretely visible through the
speaker grille) improve linearity of response and reduce distortion, while
aluminum domes on the tweeters improve sound reproduction at high frequencies by
reducing the weight of the moving part.
XF customers can import their own portable media player to interface with the
car - including iPod® and other portable audio players, or USB storage devices
such as memory sticks. In a world first, full touch-screen control of the iPod®
allows access to playlists and music search by artist, album or genre. USB Mass
Storage devices may also be accessed via the touch-screen and other players can
be connected to the car through the standard fit auxiliary input port.
The XF audio system also offers HD RadioTM technology and SIRIUS Satellite
Radio, which is growing in popularity because of its commercial-free output and
because the same network is available coast to coast, north to south. XF owners
also have the option of analog/digital TV reception, with up to nine analog and
nine digital channel pre-sets with full function control, including country or
format selection and one-touch channel-search, all through the touch-screen
menus.
JaguarSenseTM - an electronic control system that gives touch or proximity
operation to open the glovebox lid and to control the overhead console lights –
is another XF (and industry) first, and removes the need to find a small switch
which is especially useful in the dark. JaguarVoiceTM, meanwhile, offers the
driver the option of voice control for functions including audio, CD and TV,
satellite navigation, telephone, climate control, and display and memory
functions.
The XF also uses new technology to make driving safer and more relaxing, with
the choice of traditional cruise control or Jaguar’s Adaptive Cruise Control. In
tandem with normal cruise control, an Automatic Speed Limiter that allows the
driver to select a maximum speed that should not be exceeded, makes life easier
and safer. A new optional Blind Spot Monitor system remotely covers areas that
still can’t be seen either directly or by mirror, with a radar (rather than
camera-based) blind spot monitoring system. The XF has a Rear Parking Aid as
standard and a Front Parking Aid as an option – and for the first time on any
Jaguar, a Rear Camera Parking Aid offers a system that combines a rear-facing
digital video camera with the touch-screen information center.
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 program 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 modeling programs 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 program - 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 program 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 program
within Jaguar to use the next-generation CAD program C3PMG, which combines an
all-new CAD-modeling 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.
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 program - improve craftsmanship by optimizing 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.
SUSPENSION
The XF’s class-leading torsional rigidity has significant benefits for
refinement and provides the perfect platform for a suspension system that is a
further development of the XK sports car, and delivers a ride/handling balance
and steering characteristics absolutely in line with the XF’s sporting looks.
Unequal length wishbone front suspension with weight-saving aluminum components,
and multi-link rear suspension are both subframe mounted for maximum control,
including excellent straight-line stability and strong anti-dive characteristics
under heavy braking, with minimum road noise and vibration.
The only suspension variations on the XF are between the naturally aspirated V8
models, which all use finely tuned passive suspension, and the supercharged V8
models, which use Jaguar’s Computer Adaptive Technology Suspension (CATSTM). The
latest CATSTM is a sophisticated system shared with the new Jaguar XK sports
grand tourer. It uses electronically controlled, two-stage, adaptive dampers
whose characteristics are automatically adjusted within milliseconds in response
to road conditions and driving inputs, for the optimum balance between comfort
and control.
BRAKES
The XF uses large 12.83 in. x 0.79 in. (326mm x 20mm) vented front discs on all
naturally aspirated models and 13.97 in. x 1.26 in. (355m x 32mm) vented front
discs on the Supercharged model for powerful, balanced braking performance. The
rear discs on all versions measure 12.83 in. x 0.79 in. (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 center 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, through the release.
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-center feel, which
is part of the new dynamic flavor.
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.
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 TIRES
For the U.S., the XF is available with 18, 19 or 20-inch wheels; the
Supercharged being the only car in its class to have 20-inch wheels as standard.
All are cast in aluminum alloy and every design combines maximum strength with
minimum weight. All cars for the majority of markets carry the same
specification of 18-inch diameter alloy mini-spare.
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 (EDR). 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
equipment. 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 (Supercharged 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 Supercharged model there are Normal, Winter and Dynamic
modes - the last of these to allow a more purposeful driving style.
POWERTRAIN
The new XF will be available with a choice of two engines - 4.2-liter naturally
aspirated V8 petrol and 4.2-liter supercharged V8 petrol. All will have that
classic blend of power and refinement that makes Jaguar stand out from its
rivals, says Mick Mohan, XF Chief Programme Engineer:
“The XF’s engines combine effortless performance, unrivalled character and an
impeccable pedigree. The six-speed automatic transmission is the best Jaguar has
ever had. The Jaguar Sequential ShiftTM manual gearchange adds a whole new level
of functionality. This combination – already proven in the XK– produces
excellent powertrains for a very sporting Jaguar.”
The naturally aspirated V8 will be offered in Luxury and Premium Luxury models
and the supercharged V8 has its own unique specification, for a very logical,
easily understood range with only six major variants.
The 4.2 liter V8 comes in naturally aspirated or supercharged versions. With a
ribbed aluminum block and cylinder heads it is very light but extremely strong,
and its superb structural stiffness minimizes radiated engine noise and
increases mechanical reliability. The V8’s exhaust system has also been
completely retuned to remain quiet at cruising speeds but deliver a
substantially more purposeful V8 roar under hard acceleration.
In naturally aspirated form it develops 300bhp (SAE)/298PS (EEC), and 310lb ft (SAE)/411Nm
(EEC) of torque. The supercharged version uses a highly efficient rotor-type
supercharger, belt-driven from the crankshaft. It develops 420bhp (SAE)/416PS
(EEC), and 408lb ft (SAE)/560Nm (EEC) of torque from low engine speeds. Just as
important as the supercharged engine’s peak torque is the way the usable torque
is spread across a wide rev range - with at least 86 percent of the peak from
2000rpm to maximum engine speed.
A superior six-speed automatic transmission – renowned as one of the best in the
world and already proven in other Jaguars - is used on all versions of the new
XF – there is no manual gearbox option. The transmission is a key element in the
XF's sporting character, its adaptive gear-changing strategies responding both
to road conditions and the way the car is being driven, giving the smoothest
shifts and optimum performance. Adding another layer of driver focus, the
transmission is controlled by the new JaguarDrive SelectorTM with the option of
manual selection through Jaguar Sequential ShiftTM. The JaguarDrive SelectorTM
is also used to access the XF’s Sport mode which uses shift-by-wire technology
pioneered on the XK.
These high-tech, modern powertrains give every XF model outstanding performance.
The naturally-aspirated V8 model has a superb 0-60mph time of just 6.2 seconds
(0-100kph in 6.5 seconds) and has an electronically limited top speed of 155mph
(250kph). Lastly, the supercharged XF storms to 60mph in just 5.1 seconds
(0-100kph in 5.4 seconds) and, like the naturally aspirated V8 is limited to a
maximum of 155mph (250kph).
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 flavor combines the
comfort and refinement of a luxury sedan 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 sedan 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 flavor – 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. 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 also appeal to those using the XF as a ‘business’
car.
As one of the most visually striking, technically sophisticated and
driver-oriented sedan 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 flavor 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 sedan. This is the future, now.
