Challenging convention and setting its own rules, the new Jaguar XF
fuses the style and performance of a sports car with the refinement,
space and sophistication of a luxury saloon. This is the beginning of a
new era for Jaguar.
The new XF: a dramatic expression of a bold new Jaguar design language,
with a driving experience that exceeds expectations created by the
striking appearance: relaxed and confident, with outstanding ability and
control.
Resolutely true to the Jaguar philosophy of creating Beautiful, Fast
cars, the XF goes further, adding a new dimension to the marque. The
four-door XF has the visual excitement of a coupe, but room inside for
five adults to enjoy an interior wholly contemporary in style yet
uniquely Jaguar.
As well as space, the new XF’s interior ambience is enriched by crafted,
luxurious materials, sophisticated instruments and calm interior mood
lighting. Engineering excellence and attention to detail mean the XF’s
interior matches the best-in-class for refinement, while Jaguar’s
intelligent use of technology and driver-friendly Touch-screen controls
add new layers of comfort and ease of use.
Every XF model has shift-by-wire transmission control, with Jaguar’s
class-leading sequential shift system – its popularity already confirmed
by feedback from XK sports car customers – used for the first time in a
saloon. Shift-by-wire replaces manual shift linkages with electronic
commands and gives every XF rapid and very smooth gearshifts – faster,
even, than the acclaimed XK’s transmission.
The Jaguar Sequential ShiftTM System gives the driver the option of
one-touch manual gearchange control via steering-wheel mounted paddles.
There are also multiple JaguarDrive ControlTM transmission modes,
including Dynamic and Winter settings, which interact with throttle
progression, Dynamic Stability Control thresholds and shift strategy to
match mood and conditions.
But the most exciting feature of the XF’s transmission control is the
all-new JaguarDrive SelectorTM – an industry-first rotary shift
interface that combines precise, intuitive control with space-saving
packaging, to allow maximisation of interior storage options.
Other innovative functional features add more ‘surprise and delight’.
Air-conditioning vents present a flush dashboard surface until the
ignition is switched on, at which point they elegantly rotate to the
open position. Another new technology - JaguarSenseTM - introduces touch
or proximity-sensing control for overhead console lights and the
glovebox release.
Every level of audio system features at least eight speakers, with a
premium system designed in association with highly respected audio
specialist Bowers & Wilkins available on range-topping models. Radio
options now include a Digital Audio Broadcasting (DAB) system and Sirius
Satellite Radio for the North American market, while the XF technology
count includes Bluetooth® communications technology, plus optional iPod®
and MP3 player connectivity with full-function control through the
Touch-screen – and an auxiliary port on every car for other portable
audio devices.
Other available features include JaguarVoiceTM control to operate
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 SelectorTM, through the seamless
efficiency of rotating vents, to the simplicity of Touch-screen control,
the XF proves aesthetics and function can work together in perfect
harmony.”
Engineering excellence and class-leading structural rigidity are at the
heart of the new XF's construction. The advanced body structure, which
comprises high-tech materials and new-generation design techniques,
maximises strength and minimises weight to give the XF superb
performance, refinement and efficiency across its range of V6 and V8
engines. These engines include the quietest diesel engine in its class
and a supercharged V8 that delivers outstanding levels of performance.
The new XF is best in class for torsional stiffness, and with a wide
rear track displays excellent handling characteristics. These elements
underpin a dynamic ethos that is driver-focussed yet supremely
comfortable and refined. Just as its looks promise, the new XF excels
across the board, in every role from a sports car to a luxurious
long-distance cruiser.

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 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 today’s 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. Jaguar’s 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 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
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 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.
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 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 XF’s boot is the equal of anything in the
class and betters most rivals.
The XF’s 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 grille’s mesh pattern is itself an important element of external
jewellery, the woven pattern an emotional design signature that is
quintessentially British, with strong sporting connotations.
The headlamps further emphasise 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 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 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 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 XF’s 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.”
AERODYNAMICS
As well as facilitating packaging excellence, the XF’s new design
language has another significant functional advantage: for the first
time on any Jaguar, the entire body was developed using Computational
Fluid Dynamics (CFD) before the car ever saw a wind tunnel. Every area
from the outer skin to the lightweight, composite undertray to the
cooling airflow (even the shape of the exterior mirrors) was optimised
using this process. The higher, squarer tail is more efficient
aerodynamically than a lower, rounded one, and the XF’s coupe-like
roofline and subtle, raised bootlid lip improve airflow over the rear of
the car. As a result, the XF has the best aerodynamic performance, in
terms of drag, of any production Jaguar ever and is better than the
race-bred, limited edition XJ220 supercar.
The XF’s drag coefficient is just 0.29 and the front-to-rear lift
balance is precisely zero. This aerodynamic performance contributes to
impressively low wind noise, aids fuel consumption and strong high-speed
stability and, of course, is vital in ensuring ideal handling balance
through optimising drag and lift forces.
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 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 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 XF’s 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
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 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 Jaguar’s core values of authenticity of materials, what
looks like wood really is wood.
Even the XF’s 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 XF’s 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 backs.
One feature that maximises 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 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 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 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 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
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 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 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 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 throughout the XF’s 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 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 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.
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 locate a small switch, 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 centre.
ENGINEERING
Underlying the new visual design language, the XF is the product of a
new generation of design technology, materials and manufacturing
opportunities, as Phil Hodgkinson, Jaguar Programmes Director, explains:
“The engineering disciplines behind the XF are as ground-breaking as its
new design language. New development processes and computer tools
allowed us to work through the programme at a quicker pace than anything
previously; new technologies and materials combine strength with
lightness; and Jaguar craftsmanship, too, has explored new, exciting
contemporary avenues.”
Virtual Process (VP) and Virtual Series (VS) are the cutting-edge
technologies used by Jaguar to take the XF from concept to reality.
These techniques use massive computing power and sophisticated modelling
programmes to create components and even whole vehicles in the virtual
world, before building physical parts and perfecting the systems and
processes to manufacture the car. The XF represents the first time that
VP and VS tools have been used by Jaguar throughout a complete vehicle
programme - from vehicle development, to production feasibility studies,
to build planning.
But VP also dramatically improves overall quality, by allowing rapid
sign-off of component designs, and eliminating the early physical
prototype stage. With VP, when prototypes finally are built, they are
intended only to validate what is already known, not to develop areas
that are still unresolved. Fully representative vehicles are used for
physical evaluation, including on-road testing, crash-testing, hot and
cold climate testing, and durability testing. At the same time, the VS
programme is working on everything that is needed eventually to build
the car – leading to significant improvements in craftsmanship,
efficiency, even long-term serviceability.
New technology is also key to the XF’s construction. It was the first
programme within Jaguar to use the next-generation CAD programme C3PMG,
which combines an all-new CAD-modelling software package with an all-new
data-management package – opening the way to exceptional strength
without unwanted weight. The design is led by safety needs, especially
by the latest side intrusion and SUV over-ride requirements. The
reinforced passenger safety cell incorporates new thinking from the
lower side rails up.
The XF adopts the latest generation steels, especially in the upper body
– including high carbon steels, dual-phase, hot-formed boron steels, and
bake-hardened steels to form a vertical safety ‘ring’ around the
occupant cell. As well as combining strength with lightness, these
steels improve corrosion resistance, by making best use of zinc and
improving e-coat paint flow – and new thinking means that in spite of
their strength, the XF’s A and B-pillars are impressively slim, to the
benefit of both visibility and accessibility. Similarly, the lower sills
are the first component on any Jaguar to use incredibly strong,
dual-phase DP600 steel.
Second-generation Pedestrian Contact Sensing System – the acclaimed
safety system introduced by Jaguar on the XK – is included on the XF
(market dependent). This can mitigate pedestrian injury by firing
actuators that deploy the bonnet, resulting in a cushioned space between
the bonnet and engine hardpoints. The system builds on the technology
proven in the XK, using higher resolution sensing and an active
rear-hinged bonnet.
Every XF also comes with two-stage driver and front passenger airbags,
side and curtain airbags and seat occupant sensing systems to help
ensure the airbags work precisely and only as needed in every
circumstance. Front-seat occupants also have the added protection of an
anti-whiplash system and ‘soft-landing’ technology in the seat-belt
retractors to soften contact with the front airbags.
Other changes - many of them made possible by extensive use of the
Virtual Process during the development programme - improve craftsmanship
by optimising the manufacturing process. Close attention to optical
quality creates the smallest, most consistent panel gaps and other new
measures improve resistance to minor impacts, making accident repairs
easier and less expensive, so contributing to significant
cost-of-ownership benefits.
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 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 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 326mm x 20mm vented front discs on all naturally
aspirated models and 355mm x 32mm vented front discs on the SV8 model
for powerful, balanced braking performance. The rear discs on all
versions measure 326mm x 20mm.
An extremely stiff pedal box contributes to a particularly solid pedal
feel, and the brake assistance is tuned to give a very progressive feel,
while softening the initial response.
The XF uses Jaguar’s Electric Parking Brake, with a small and neat,
chromed release in the centre console. As the XF’s braking system
communicates electronically with the shift-by-wire technology of the
JaguarDrive SelectorTM function, so the Parking Brake is released
automatically as Drive is selected – although the Parking Brake can also
be engaged and disengaged manually if appropriate.
STEERING
Variable ratio power-assisted steering is standard on every version of
XF, for reduced parking effort at low speeds and greater precision and
feedback at higher speeds - and especially for positive weight to the
on-centre feel, which is part of the new dynamic flavour. Steering
effort at manoeuvring speeds is also reduced on diesel models.
The new XF adopts an electronic steering column lock - for compatibility
with passive entry mode and the Jaguar Smart Key SystemTM. There is no
longer a key barrel on the column, however the electronic lock satisfies
Thatcham security legislation for the UK market.
The XF’s steering wheel includes cruise-control, JaguarVoiceTM (where
fitted) and audio controls - including volume, and radio channel
pre-sets. The source button toggles through AM/FM/CD, plus any external
device functions. The select buttons allow features such as CD track
change, radio channel pre-set selection or iPod® or MP3 track change if
such a device is in use.
WHEELS AND TYRES
Depending on market and model, the XF is available with 17, 18, 19 or
20-inch wheels; the SV8 being the only car in its class to have 20-inch
wheels as standard. All are cast in aluminium alloy and every design
combines maximum strength with minimum weight. To satisfy Thatcham
security stipulations, there are also 20 variations of anti-theft
locking nut. All cars for the majority of markets carry the same
specification of 18-inch diameter alloy mini-spare.
For major European markets, cars with 17 and 18-inch wheels are fitted
with the Jaguar Tyre Repair System as a space and weight-saving
alternative to the ‘mini-spare’. This replaces the spare wheel, jack and
tool kit, and can effect a temporary repair of any puncture of up to 6mm
diameter in the tread area - sealing the hole and re-inflating the tyre
to enable the car to be driven to where a permanent repair or
replacement can be carried out. When fitted in lieu of a spare wheel,
the Jaguar Tyre Repair System liberates an additional 40 litres of
stowage space under the boot floor.
DRIVER AIDS
The XF’s main control module governs many key safety functions including
Emergency Brake Assist (EBA), Electronic Brakeforce Distribution (EBD),
Anti-lock Braking System (ABS), Traction Control through engine and
brake intervention, Dynamic Stability Control (DSC), Cornering Brake
Control (CBC) and Engine Drag Torque Control. And for the first time,
the XF adds Understeer Control Logic, which has been designed to
mitigate understeer by intervening through the engine management and
braking systems to decelerate the car and help restore grip to the front
wheels.
A two-stage DSC system similar to that featured on the new XK is
standard. It combines the normal on-off switchable DSC function, which
reacts as soon as it detects slip, with Trac DSC, which allows more slip
before intervening – better for a more sporting driving experience. It
also allows a degree of wheel overspin on deep soft surfaces, which is
essential for running with snow chains. The system defaults to normal
‘DSC on’ with each ignition-on sequence.
In Dynamic Mode (SV8 only), pressing and holding the DSC button fully
disables the system, allowing an experienced driver to exploit fully the
capability of the chassis, where conditions allow. Mode selection is
confirmed on the instrument cluster display.
Also new on XFs fitted with Adaptive Cruise Control (ACC) is Electronic
Brake Prefill. This senses any rapid throttle lift-off and initiates a
small brake hydraulic pressure build-up in anticipation of the brakes
being applied, to give better pedal response and slightly shorter
stopping distances.
JaguarDrive ControlTM offers different modes that interact with the DSC
system, engine and gearbox, to change the characteristics of engine
mapping, transmission shifts and brake interventions depending on
driving conditions and circumstances. On naturally aspirated cars
JaguarDrive ControlTM has Normal and Winter modes, on the SV8 model
there are Normal, Winter and Dynamic modes - the last of these to allow
a more purposeful driving style.
POWERTRAIN
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 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.”
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 XF’s 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 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 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).
DRIVING DYNAMICS
Delivering the highest levels of driver enjoyment is a must for any
Jaguar, so it is essential that the XF’s driving dynamics live up to its
powerfully athletic looks. Underpinned by the stiff platform, wide track
and finely resolved suspension, steering and brakes, the XF’s dynamic
flavour combines the comfort and refinement of a luxury saloon with the
grip, balance, responses and stability of a sports car. The result is a
dynamic character that delivers real driver involvement, as far removed
from the premium saloon crowd as are the XF’s bold looks.
Chief Engineer, Vehicle Integrity Mike Cross explains the development
processes behind the new car:
“Two key objectives defined the XF’s dynamic flavour – firstly that its
driving abilities should match its sporting coupe-like looks, and
secondly that it should have Jaguar’s unique balance of ride, handling
and refinement. The XF succeeds on all counts and the result is a very
special experience.”
Every XF model uses Jaguar Sequential ShiftTM transmission control,
allowing manual gear selections in the automatic transmission via
‘paddle’ switches mounted on the rear of the steering wheel, in either
Drive or Sport mode.
But sporty is only half the XF driving dynamics story – refinement is
equally important, and equally impressive. With its stiff shell, smooth
powertrains and extraordinary attention to acoustic management
(including a secondary bulkhead and dual-isolated subframe on all
versions), the XF has outstanding NVH performance to match the best in
class. At 30mph (50kph), for instance, the interior noise level is only
65.6dB, below its nearest BMW 5-Series rival, even when the XF is on
larger wheels. Special attention has been paid to the V6 diesel, whose
sound quality is so impressive it is hard to tell which engine lies
beneath the bonnet. The V8 XF takes lessons from the XK with an exhaust
system tuned for an overtly sporty sound quality, especially when
accelerating hard – again, just as the looks promise.
IN SUMMARY
The new XF is a milestone for Jaguar. In every respect it signals the
future of the marque – and yet it remains true to the essence of what
has always made great Jaguars the cars they are.
The new XF is more than just a strikingly beautiful Jaguar. It also
appeals from a rational perspective to buyers of all ages who expect
value for money, even from a luxury marque. XF pricing is extremely
competitive throughout the range, in spite of rich standard feature
specifications and extensive use of advanced technologies.
And XF buyers can look forward to enjoying continued fiscal benefit.
Anticipated strong residual values will appeal to those using the XF as
a ‘business’ car, while the V6 diesel in particular has competitive
emissions levels, with the accompanying tax advantages for company car
users and fleet buyers.
As one of the most visually striking, technically sophisticated and
driver-oriented saloon cars that the company has ever produced, the XF
is synonymous with the forward-looking focus that now defines the Jaguar
brand. Its design language is entirely new, its performance and dynamic
flavour support – even eclipse - its sporting looks, and intelligent use
of advanced technology and innovative control interfaces set the XF far
apart from any other premium sports saloon. This is the future, now.
