Company Press Release) THE NEW JAGUAR XF
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 XFs interior ambience is enriched by
crafted, luxurious materials, sophisticated instruments and calm
interior mood lighting. Engineering excellence and attention to
detail mean the XFs interior matches the best-in-class for
refinement, while Jaguars 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 Jaguars
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 XKs transmission.
The Jaguar Sequential Shift TM System gives the driver the option of
one-touch manual gearchange control via steering-wheel mounted
paddles. There are also multiple JaguarDrive Control TM 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 XFs transmission control is
the all-new JaguarDrive Selector TM 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 - JaguarSense TM
- 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 JaguarVoice TM control to operate
navigation 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 Selector TM, 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
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.

THE XF IN DETAIL
DESIGN - EXTERIOR
The 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
emphasises contemporary and emotional themes while remaining
unmistakeably 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
The new XF enters the range in the niche previously occupied by
much-loved mid-sized Jaguar saloons such as the original XJ Series 1
(a car that was smaller than todays XJ). But unlike many D/E
segment premium saloons, the new XF pushes boundaries away from the
three box style and creates a four-door, five-seat saloon with
strong, coupe-like lines. Jaguars new design language, which
debuted with the new XK sports car, is applied to a saloon car for
the first time in XF. The visual step forwards is as significant as
it is obvious - the XFs 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 programme imperative, so the XF is proportioned to provide
interior space and levels of comfort that challenge for
best-in-class honours. At 4961mm long and 1877mm wide, on a lengthy
2909mm wheelbase, the XF is 45mm longer and 25mm wider than its
nearest 'dimensional' competitor, the Audi A6 with even greater
advantages over the BMW 5-Series, Lexus GS300 and Mercedes-Benz
The XFs 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. The XFs 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 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 540 litres (500 with a
spare wheel) the XFs boot is the equal of anything in the class and
betters most rivals.
The XFs Jaguar character is defined by its face centred around a
bold intake grille which provides a focal point for the feature
lines which stream back over the bonnet and cabin, it has inherent
visual strength. The grilles mesh pattern is itself an important
element of external jewellery, the woven pattern an emotional design
signature that is quintessentially British, with strong sporting
The headlamps further emphasise the way in which Jaguars 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 the overall shape; a subliminal
reminder of the Jaguar saloon 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
bootlid is an example of this.
The stance of the XF is new for a modern-day Jaguar saloon. It gives
the car a ready to pounce look that suggests latent power and
energy, the strong wedge profile of the waistline imparting a
forward-biased dynamic before the car has even turned a wheel.
The XFs 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 emphasise
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 unmistakeable
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 tyre
combination has been engineered to have the same rolling radius,
giving a consistent wheel to body visual relationship. The XF is
fitted with either 17, 18, 19 or 20-inch alloy wheels, the
supercharged SV8 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 jewellery. The distinctive bright
aluminium 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 centre, while the venturi shape below
the tail which hints at the XFs sophisticated aerodynamics is
positioned above large, stylised 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 SV8. Externally, with the exception of wheel styles and a badge
on the SV8, 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
saloon and yet it could only be a Jaguar.
As well as facilitating packaging excellence, the XFs 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
XFs 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
The XFs 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.
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
saloon design but also the sense of being in a perfectly
proportioned, agile car. There is also comfort of course but it
is the c raftsmanship, 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 maximises 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 best-in-class rear seat width means tall adults can sit in
complete comfort. And while the XF roofline might say coupe, the
rear headroom says saloon better than many rivals.
Just as the XFs exterior defines a new design direction, its
interior moves from traditional themes to contemporary, sporting
luxury - emphasised by surprise and delight features such as the
JaguarDrive Selector TM and the rotating vents; through the use of
sophisticated new materials; and by all-new graphics and interior
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
flavour - 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 aluminium
finisher runs continuously through the 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 saloon in
the 1960s underlines what is a luxurious interior, with veneers
including Satin American Walnut, Burr Walnut and a very modern,
straight-grained Rich Oak that works particularly well with textured
aluminium highlights that are used in every XF to enhance the
contemporary, technical feel. And true to Jaguars core values of
authenticity of materials, what looks like wood really is wood.
Even the XFs headlining material is a step on from conventional
materials. Using a modern technical weave called Morzine, the entire
cabin roof and A-pillars are trimmed in this eye-catching,
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 centre 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 centre 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 on the backs of the front seats, while the
rear centre 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 boot is more than 500 litres,
with the possibility to add even more storage space depending on
factors such as whether the space-saver spare wheel or Jaguar Tyre
Repair System is fitted. At its maximum 540 litres, the XFs boot is
equal to the best in class and there is still the option to
liberate a further 420 litres of space by folding down the rear seat
One feature that maximises space efficiency is the JaguarDrive
Selector TM, 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 XFs individuality.
Get into an XF and the start button in front of the JaguarDrive
Selector TM pulses red, like a heartbeat. Press this button to start
the engine and the cast alloy JaguarDrive Selector TM rises into the
palm of your hand. Simultaneously, the navigation system initialises
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 Selector TM, 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 couldnt be simpler.
Phosphor blue mood or halo lighting echoes the ambience you might
find in a favourite 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 Selector TM
console, the start-stop button and Electric Parking Brake gives a
soft glow that indicates their positions without distracting the
Mood lighting is also incorporated into the header console, bathing
the centre 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 aluminium-coloured
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 moulded halo material around the JaguarDrive
Selector TM 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 emphasise
harmony and sophistication in the interior.
To say that luxury comes as standard on the XF is an understatement.
Front seats are electrically adjustable, with a minimum of eight-way
seat adjustment for the driver and front passenger, while the SV8
offers 16-way drivers seat and 12-way passengers 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 throughout the XFs development.
The three trim levels offer combinations of Bond Grain leather and
Softgrain leather in a subtle colour palette. The Luxury trim level
uses non-perforated Bond Grain leather for the seat facings with
matching material for the twin needle stitched facia and door top
rolls. Premium Luxury and SV8 have a sumptuous interior with
Softgrain leather used throughout for seats, facia and door top
rolls, while perforated Softgrain 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
cars in-built telephone system and phone calls can be controlled
either via the Touch-screen or hands-free, using the steering wheel
controls or JaguarVoice TM 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 320W Premium Sound System has a DSP
amplifier linked to nine speakers: eight premium door-mounted and
(through clever packaging of the boot area) a 32-litre sub-woofer
for enhanced bass. The Bowers & Wilkins 440W 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 aluminium 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 Digital Audio Broadcasting (DAB) and
in North America, Sirius Satellite Radio. Sirius 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 analogue/digital TV reception, with up to
nine analogue 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.
JaguarSense TM - 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 locate a small switch, especially useful in the
dark. JaguarVoice TM, 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
The XF also uses new technology to make driving safer and more
relaxing, with the choice of traditional cruise control or Jaguars
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 cant 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 centre.
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,
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
New technology is also key to the XFs 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 XFs 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
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.
The XFs 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 XFs sporting looks. Unequal length
wishbone front suspension with weight-saving aluminium 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 V6 petrol,
V6 diesel and V8 naturally aspirated models, which all use finely
tuned passive suspension, and the SV8, which for all markets uses
Jaguars Computer Adaptive Technology Suspension (CATS TM). The
latest CATS TM 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.
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 Jaguars Electric Parking Brake, with a small and neat,
chromed release in the centre console. As the XFs braking system
communicates electronically with the shift-by-wire technology of the
JaguarDrive Selector TM 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.
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
System TM. There is no longer a key barrel on the column, however
the electronic lock satisfies Thatcham security legislation for the
The XFs steering wheel includes cruise-control, JaguarVoice TM
(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
The XFs 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.
I n 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 Control TM 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 Control TM 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.
The new XF will be available with a choice of four engines -
2.7-litre V6 turbodiesel, 3.0-litre V6 petrol, 4.2-litre naturally
aspirated V8 petrol, and 4.2-litre supercharged V8 petrol (depending
on market). 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 XFs 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
Shift TM manual gearchange adds a whole new level of functionality.
This combination already proven in the XK produces excellent
powertrains for a very sporting Jaguar.
Both petrol and diesel V6 engines are offered in Luxury and Premium
Luxury models; the naturally aspirated V8 will be Premium Luxury
only (and Luxury for US models) and the supercharged SV8 has its own
unique specification, for a very logical, easily understood range
with only six major variants.
The Euro IV compliant twin-turbocharged 2.7-litre 24-valve V6 diesel
delivers high efficiency, high performance and class-leading
refinement its headline figures including 207PS (EEC) and 435Nm
(EEC) of torque. With its Compacted Graphite Iron (CGI) cylinder
block and aluminium cylinder heads it is the lightest diesel engine
of its type and size - making a significant contribution to the new
XFs power-to-weight ratio, performance and fuel economy.
The V6 diesel features the latest generation high-pressure Common
Rail direct-injection, multiple pilot injection, and
piezo-electric injection control, allowing sophisticated management
of the injection patterns to make combustion smoother and quieter.
Four valves per cylinder and advanced combustion chamber shapes
contribute to high combustion efficiency with low combustion noise,
alongside very low mechanical noise levels.
Emissions are further reduced by using twin variable-geometry
turbochargers with electronic control, exhaust gas recirculation,
and a variable-swirl intake system. Using two small turbochargers,
with drive-by-wire throttle control, rather than one larger unit,
also gives a quicker, smoother response.
The 3.0-litre V6 petrol engine is another compact, lightweight,
all-aluminium design with four overhead camshafts, four valves per
cylinder, VCP Continuously Variable Cam Phasing and variable
geometry air intakes. It produces 240bhp (SAE)/238PS (EEC) and 221lb
ft (SAE)/293Nm (EEC) peak torque - with more than 80 percent of peak
torque from below 1500rpm to maximum engine speed at 6800rpm.
Variable Camshaft Phasing produces faster response and performance
at all engine speeds - with more torque at low speeds and maximum
power at high speeds. It also provides internal exhaust gas
recirculation, reducing both hydrocarbon and NOx emissions.
The 4.2-litre V8 comes in naturally aspirated or supercharged
versions. With a ribbed aluminium block and cylinder heads it is
very light but extremely strong, and its superb structural stiffness
minimises radiated engine noise and increases mechanical
reliability. The V8s 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 engines 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 Selector TM with
the option of manual selection through Jaguar Sequential Shift TM.
The JaguarDrive Selector TM is also used to access the XFs Sport
mode which uses shift-by-wire technology pioneered on the XK.
These high-tech, modern powertrains give every XF model outstanding
performance. The 2.7-litre V6 diesel reaches 60mph in just 7.7
seconds (0-100kph in 8.2 seconds) and has a top speed of 143mph
(229kph). The 3.0-litre V6 petrol version sprints to 60mph in 7.9
seconds (0-100kph in 8.3 seconds) and goes on to reach 148mph
(237kph). 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 SV8 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).
Delivering the highest levels of driver enjoyment is a must for any
Jaguar, so it is essential that the XFs driving dynamics live up to
its powerfully athletic looks. Underpinned by the stiff platform,
wide track and finely resolved suspension, steering and brakes, the
XFs 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
XFs bold looks.
Chief Engineer, Vehicle Integrity Mike Cross explains the
development processes behind the new car:
Two key objectives defined the XFs dynamic flavour firstly that
its driving abilities should match its sporting coupe-like looks,
and secondly that it should have Jaguars 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 Shift TM 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.
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.
