XF : Full Press Release
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
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
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
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
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

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
As Design Director Ian Callum
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 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 E-Class.
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,
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 supercar.
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
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 lighting
Jaguar Cars interior designer
Alister Whelan says the inspiration for the XF cabin was pure,
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, 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 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
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 driver.
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
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 functions.
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
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
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 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.
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
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
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
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 UK market.
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 floor.
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
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
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
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
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
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
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
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
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
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.
