"Built in the tradition of great grand tourers, with
state-of-the-art engineering, aerospace-inspired construction and outstanding driving dynamics, the new
XK is the latest in a long line of legendary performance Jaguars." Mike O'Driscoll, Managing
Director, Jaguar Cars.
The Jaguar sports car experience moves on to a new level with the European introduction of a new XK
coupe and convertible.
With all-new engines, even more dramatic looks, a new interior, an advanced light weight aluminium
body structure and a wider range of models, the new XK builds on 60 years of legendary performance to
deliver the best of everything Jaguar.
Designated 2010 model year, with Australian deliveries commencing in Q1 2010, the new XK range not
only stands out from the crowd, it stands apart. The combined efforts of Jaguar's designers and
engineers have produced a car that utilises advanced technologies at a higher level than ever before.
The benefits of the XK's light weight but incredibly stiff and strong chassis are already
acknowledged. Not only does this architecture bring dynamic benefits thanks to its torsional rigidity,
it also offers excellent safety and crash repair features - and provides the ideal base to optimise
performance across the board, including fuel economy and CO2 emissions.
The all-new AJ-V8 Gen III engines are the most efficient Jaguar has ever produced. They deliver
significantly more power and torque than the previous generation of engines: 375 kW and 625 Nm in the
new supercharged XKR and 283 kW and 515 Nm in the XK models.
With the introduction of these all-new 5.0 litre direct-injection V8 engines comes a new level of
performance for the XK, with improved acceleration from standstill and stunning in-gear acceleration
times. All models are electronically limited to a maximum speed of 250 km/h, but the 0-100 km/h sprint
for naturally aspirated coupe models falls from 6.2 to 5.5 seconds, while for the supercharged XKR
coupe, 0-100 km/h is reduced from 5.2 to 4.8 seconds.
And yet thanks to a combination of excellent powertrain efficiency and the XK's advanced light
weight body architecture, all XKs offer strong fuel economy and impressive CO2 emissions ratings. Fuel
economy is comparable to the previous generation of XK - despite the significant increases in
performance - and CO2 emissions from each engine are better than the out-going versions, with the
naturally aspirated version improving on that of the 4.2 litre V8 by two per cent, while the
supercharged engine produces one per cent less CO2 than its predecessor. Indeed, the new generation XK
is among the very best in both fuel economy and emissions for any V8 engined sports car.
"With an all-new, supercharged AJ-V8 engine and dramatic new looks, the new XKR has all the
performance, power and panache that you expect in the ultimate sporting Jaguar." Mike O'Driscoll,
Managing Director, Jaguar Cars.
Allowing the engines to optimise their power is one of the most sophisticated transmissions
available. Jaguar's acclaimed electronically controlled, six-speed ZF 6HP28 transmission offers an
unparalleled combination of driver control matched to virtually undetectable gearshifts. With control
either from steering wheel-mounted paddles or full automatic mode via the JaguarDrive SelectorTM,
which is new for the 2010 Model Year XK. The transmission is now paired with an advanced electronic
differential on the XKR model to ensure it accelerates even faster, handles more precisely and sets
new standards of dynamic control and excellence.
In addition to the many changes under the skin, the new XKs are visually different to the previous
model. Each still looks just like a Jaguar should look - powerful and elegant - but all models, coupe
and convertible, introduce revised exterior styling that underlines Jaguar's contemporary thinking on
design.
Inside, quality levels are raised even further with new interior trim and finishes that
demonstrate Jaguar's renowned craftsmanship, plus even more comprehensive specification.
The driver is the centre of attention, with exciting new ideas, including the acclaimed JaguarDrive
Selector™, Adaptive Dynamics with Active Differential Control and comfort features such as heated and
cooled seats - taking the driving experience of the new XK range to even higher levels of luxury
alongside the improved performance.
"The new XK delivers more power, more performance and more technology - without compromise. It
moves the Jaguar sports car experience on to a whole new level." Mick, Mohan, Director, Jaguar
Programmes.

The new XK range in detail
The new XK is a sophisticated grand tourer with the 'heart' of a true sports car, combining
effortless high-performance and state-of-the-art V8 powertrains with a new layer of advanced
technologies, intuitive control, and Jaguar's superbly crafted, new-fashioned luxury interiors.
The range will continue to include both naturally aspirated XK and supercharged XKR, available
in 2+2 coupé or convertible body styles.
All-new AJ-V8 Gen III 5.0-litre direct-injection engines bring significant improvements in power
and torque and they do so with no compromise in terms of fuel economy and emissions.
In both respects, every car in the new XK range, in spite of such large performance and
flexibility gains, is comparable to their predecessors.
The impressive fuel economy is directly attributable to the combination of the XK range's
lowest-in-class weight and the all-new AJ-V8 Gen III engines. As well as the intrinsic advantages
of the engines' exceptionally light weight and compact dimensions, these technically advanced
all-aluminium four-cam power units offer a number of features that deliver power with very high
efficiency, including spray-guided direct injection (SGDI), which improves performance and economy,
and dual independent variable cam timing (DIVCT), which benefits performance and economy and also
reduces emissions.
The model range for the new XK comprises just two clear choices - XK and XKR. Each has its own
specific choices of trim, colour and fine detail, but every one has the same underlying sporting
character and clear emphasis on efficient performance, luxury and craftsmanship.
Beyond that, the XK vehicle personalisation programme also offers an extensive range of
accessories that allow the customer to add further bespoke touches - inside and out.
Stunning performance increases
In naturally aspirated form, the new AJ-V8 Gen III 5.0-litre engine delivers 283 kW of power and
515 Nm of torque - respectively 26 and 23 per cent more than its 4.2 litre predecessor.
The XKR's supercharged 5.0-litre AJ-V8 Gen III R delivers a mighty 375 kW and 625 Nm of torque -
improvements of 23 and 12 per cent respectively over the supercharged 4.2 litre engine.
On the road, while maximum speed remains under electronic control at 250 km/h, these power and
torque gains allied to the light weight aluminium body architecture of the XK dramatically reduce
acceleration times. For the naturally aspirated XK Coupe, 0-100 km/h is reduced from 6.2 to 5.5
seconds; for the supercharged XKR Coupe, 0-100 km/h is reduced from 5.2 to 4.8 seconds.
The supercharged XKR is also impressively efficient, with an average consumption of 12.3 l/100
km and a CO2 rating of 292 g/km - an improvement over the previous XKR.
The Looks - exterior styling
Visible changes on the new XK and XKR reflect the significant changes under the skin.
Carefully revised exteriors take the seductive, powerful, elegant lines that define Jaguar's new
design language and interpret them for a dramatically beautiful 2+2 sports car whose shape is even
more taut, powerful and athletic. Evoking the essence of performance long before it moves, the new
XK family shape is unmistakably 'new-school' sporting Jaguar: wholly contemporary, finely sculpted,
efficiently packaged and precisely detailed.
Design Director Ian Callum outlines the new design features on the XK range: "The current XK
was the first car to signify a new generation of Jaguars - cars that have honed our image every bit
as successfully as the original XK120 or E-type. Now the new XK range reinforces that message. The
cars' visual agility and beautiful lines have been enhanced with a distinctive new front end, rear
lights and revised body styling that gives every model even more presence."
The exterior changes for both the naturally aspirated XK and the supercharged XKR are
highlighted by a distinctive and purposeful new front bumper design, new LED rear lights and a new
lower rear body valance. New LED rear light clusters incorporating fog lamps plus twin reversing
lamps (rather than the previous single units) give each car in the new XK range a unique 'night
time signature', while LED technology is also included in the integrated side repeater and approach
lamps in the new exterior mirrors. Each car in the new XK range also features new engine covers and
revised, body-coloured side power vents.
Beyond the shared changes, subtle differences in detail distinguish the new XK from the new XKR.
The naturally aspirated XK and the supercharged XKR display purposeful front bumper features with
stylish, chrome-detailed inserts and further chrome detailing to the upper mesh grille. The XKR is
set apart by also featuring chrome on its lower mesh grille - which is finished in black on the XK.
All models now feature chrome detailing on window surrounds and rear signature blade, and in
addition the XKR comes with a new lower rear valance that is finished in body colour and a revised
tailpipe design further emphasising its sporting performance.

The Looks - interior styling
Contemporary, sporting luxury, exceptional quality of craftsmanship, and Jaguar's renowned attention to
detail are the keynotes of the new XK range's enhanced interiors. The cabin is clean, elegant and spacious,
and remains entirely in harmony with the sporty character of the revised exterior.
The luxury character of the new XK range, however, is guaranteed, regardless of the customer's choice
of body style - hard-topped coupé or fabric-roofed convertible. Both benefit from the inherent strength of
Jaguar's light weight aluminium architecture, which means that as well as being the lightest body structure
in its class, the XK and XKR's shells also have the highest torsional strength. And that exceptional
rigidity, with or without a fixed roof, means creak and rattle-free refinement on virtually any surface,
however unforgiving.
Beyond that, the convertible's triple-lined fabric roof gives a level of fit and stability even at very
high speeds that minimises wind noise and other road noise and includes a luxurious interior finish almost
indistinguishable from a fixed roof. In addition, the XK and XKR feature luxurious Jaguar Suedecloth
headlining as standard.
It can, however, be powered up or down at the touch of a button in less than 18 seconds. And when it is
lowered, the convertible's flush-folding roof retracts completely into the body work behind the rear seats,
under a smooth cover that retains the elegant, sporty lines of the car.
Nor does the convertible compromise the new XK range's safety, for its roll-over protection system,
which remains hidden unless it is needed, deploys instantaneously as necessary to provide occupants with
the highest levels of protection.
For both coupé and convertible, the latest trim and feature enhancements are highlighted by the
JaguarDrive Selector™, which is very neatly and elegantly packaged in the centre console. The welcome
to the car is also enhanced by new, bright treadplate inserts. Many of the other changes emphasise very
high levels of Jaguar craftsmanship with new jewel-like touches. The three-spoke steering wheel now has
a leather-wrapped lower spoke, and Jaguar's striking 'growler' badge. The new XKR's instruments now
further emphasise its performance character with red pointers, while all models adopt a new white
illumination for their instruments.
The XK and XKR now have 16-way adjustable seats with heating and memory functions, adjustable side
bolsters and new cooled seats as standard.
The door casings are even more luxuriously crafted than before, with saddle-stitched lines and a new
interlayer to give a softer touch to the top shoulder of the casing. The leather door pulls also
introduce twin-needle stitching and a soft-feel interlayer. In each door, the modified seat switch pack
now includes single-piece chrome 'highlight' switches.
There is a wide choice of interior colour options, including a new combination of Ivory seating with
Oyster upper cabin trim and Oyster carpets.
Real wood veneers remain an important part of Jaguar craftsmanship and now include a new Rich Oak
veneer option for the XK. The new XK also offers the choice of Ebony, while the new XKR offers its own
unique alternative in Dark Oak. A Knurled Aluminium veneer is also available on XK, while Dark Mesh
Aluminium is available on XKR.
Body architecture
Globally recognised as one of the key elements in Jaguar's intelligent use of advanced technology,
the XK's industry-leading light weight architecture constructs the entire body shell (the internal
chassis structure and external body panels) from a combination of pressed, cast and extruded aluminium
alloy components. These are riveted and bonded together using techniques originally developed in the
aerospace industry and adapted for automotive use by Jaguar.
The result is a body shell with a depth of quality that is 'cast' in the highest structural
integrity.
It is also the lightest shell in its class by a significant margin and the most torsionally stiff.
That all-round strength, remarkable rigidity and exceptional lightness underpin many aspects of the
XK's excellence, from fuel-efficient performance to its inherent safety, durability and refinement -
and, of course, its precise chassis dynamics.
Mike Cross, Vehicle Integrity Chief Engineer, explains the benefits of this advanced body
architecture: "Lightness benefits agility, and agility with high performance defines the
exhilarating yet refined nature of the Jaguar XK. It accelerates harder, stops more quickly and
handles with true precision - setting new standards of dynamic excellence."
All-new XK Powertrain Technology
- New AJ-V8 Gen III engines are more compact, more efficient and much more powerful
- 283 kW, 515 Nm, 264 g/km CO2, 11.2 l/100 km combined fuel economy (naturally aspirated)
- 375 kW, 625 Nm, 292 g/km CO2, 12.3 l/100 km combined fuel economy (supercharged - the Gen IIIR)
- Conforms to EU 5 emissions regulations
- High efficiency, sixth-generation twin vortex supercharger on Gen III R engine
- Central spray-guided direct-injection increases efficiency and torque
- Torque-actuated variable camshaft timing on all four camshafts for improved response and efficiency
- Cam profile switching in naturally aspirated engine
- Variable-geometry inlet manifold on naturally aspirated engine further increases low and high-end torque
- Low-friction design optimises fuel consumption
Since the first XK was launched in 1948, generations of powerful yet refined engines have played
a crucial role in establishing the unique 'character' and 'pedigree' of Jaguar cars. Now, the new
5.0 litre direct-injection engines continue that tradition, delivering increased power and torque
with reduced emissions and impressive fuel economy. Available in two versions, the 375 kW
supercharged V8 petrol and the naturally aspirated 283 kW version, the new AJ-V8 Gen III engines
exemplify Jaguar's reputation for innovation and engineering excellence.
Commenting on the new engine range, Ron Lee, Powertrain Group Chief Engineer, said: "We set
ourselves the challenge of developing an all-new V8 engine series that improved on the performance
and the refinement of the excellent 4.2 litre, with comparable fuel economy and improved emissions.
We have achieved that with the AJ-V8 Gen III - a superbly responsive power unit of unsurpassed
efficiency."
Jaguar's all-new petrol V8s have been designed in-house, using the expertise of powertrain
engineers at Jaguar's advanced research and development centre at Whitley, Coventry, UK.
Malcolm Sandford, Engine Group Chief Engineer, explains the concept behind the project: "The
emphasis was on delivering efficiency, superior dynamic response and highly accessible low-end
torque suited to real-world driving, without compromising power at higher engine speeds."
The results are clear to see. Performance has been increased by 29 per cent and 23 per cent on
both naturally aspirated and supercharged engines yet both the naturally aspirated and supercharged
engines meet EU 5 emissions regulations. Despite the significant increases in power, CO2 emissions
of the naturally aspirated engine improve on that of the outgoing 4.2 litre V8, while the
supercharged engine also produces less CO2 than its predecessor.
Top of the class in more ways than one
Both new AJ-V8 Gen III petrol engines are state-of-the-art in every sense. The technical
features have been engineered to deliver unparalleled efficiency, refinement, power and torque for
which Jaguar is famous, combined with the lowest possible emissions. Low-speed torque characteristics
and throttle response are world-class.
Summarising this achievement, Jaguar Programme Director, Mick Mohan, said: "These engines have
been designed by our Powertrain team of over 800 people for the next generation of Jaguar cars. They
deliver fantastic straight-line performance and response which is second to none. The combination of
power, refinement and driveability is what our customers expect of Jaguar. They are smooth around
town, but when you want to drive quickly, the engines are hugely responsive and deliver that classic,
Jaguar sound quality."
Light, robust and very strong
The new V8 engines are built around a stiff, all-new, aluminium block with cast-in iron liners
and cross-bolted main bearing caps to reduce noise, vibration and harshness. For the first time at
Jaguar the blocks are high pressure die-cast, providing a superior finish and greater dimensional
accuracy. The engines use aluminium heads, with four valves per cylinder and strong,
spheroidal-graphite cast-iron crankshafts and forged steel connecting rods. The cylinder heads for
the first time are specified with a secondary (recycled) aluminium alloy thus reducing the
environmental impact of manufacturing the new engine.
The new 5.0-litre direct injection petrol engines are more compact than their predecessors.
Overall engine length has been reduced by 24 mm by relocation of the oil pump within the engine
architecture. This length reduction improves engine bay packaging in support of enhanced safety
cell performance while ensuring overall engine weight is virtually unchanged.
New supercharger - more for less
A sixth-generation, twin vortex system (TVS) supercharger is fitted to the XKR's 375 kW engine.
It is a compact Roots-type unit, feeding air through twin intercoolers, which in turn are
water-cooled by their own discreet cooling circuit. The high helix rotor design improves the
supercharger thermodynamic efficiency by 16 per cent over its predecessor. It also improves noise
quality to the point where the unit is now virtually inaudible (making supercharger whine a thing
of the past). The intercoolers reduce the temperature of the pressurised intake-air and so optimise
power and efficiency.
The new air intake has been radically redesigned compared to the previous V8. The intake air
path is a direct feed to the supercharger inlet from the centrally mounted front throttle body. Air
is delivered through twin air boxes, which reduce flow loss and further increase efficiency.
Mechanically, the new supercharger and its intercoolers are efficiently packaged in the 'V' of
the engine to deliver a low overall engine height in support of pedestrian safety requirements.
Industry-first direct injection - power with economy
One of the key features of the new petrol engines is an industry-first, centrally-mounted,
multihole, spray-guided fuel injection system, delivering fuel at a pressure of up to 150 bar
directly to the cylinder. This substantially contributes to improved low-speed, dynamic response.
The positioning of the injectors ensures fuel is precisely delivered to the centre of the
combustion chamber, maximising air-fuel mixing, and improving combustion control. Fuel is
delivered via twin, high-pressure fuel pumps that are driven via auxiliary shaft in the all-new
engine block.
The charge cooling effects of the direct-injection fuel system have allowed the compression
ratio of the naturally aspirated engine to be raised to 11.5:1, further improving the engine
economy. The supercharged engine also benefits from an increase from 9.0:1 in the previous 4.2
litre to 9.5:1.
During the engine warm-up phase, the combustion system employs multiple injection mode
strategies to deliver 50 per cent more heat for fast catalyst warm-up and substantially reduced
emissions.
Torque-actuated variable-camshaft timing improves efficiency
A new type of variable camshaft timing system (VCT) introduces another new technology. The
four VCT units are activated by the positive and negative torques generated by opening and
closing the intake and exhaust valves, instead of by oil pressure. This has allowed the engine
oil pump to be reduced in size, saving energy and reducing fuel consumption.
VCT units work independently on all four camshafts with 62 degrees of authority on the
inlet cams and 50 degrees of authority on the exhaust cams. Timing is optimised by the engine
control unit for torque, power and economy at every point in the engine's speed range.
The new VCT units are capable of a response rate up to three times faster than before, with
actuation rates in excess of 150 degrees per second.
This delivers a more immediate engine response to the driver's demand.
The naturally aspirated engine is also equipped with camshaft profile switching (CPS) on
the inlet camshaft. Depending on the engine's running conditions and the demands of the driver,
the CPS will switch between a profile that is ideal for low-speed driving, and another which
gives increased valve lift for high performance.
Hydraulically-actuated two-piece tappets switch between profiles on the tri-lobe camshaft
altering both the lift and duration. The cam lobe profile selected for lower engine speeds has
a duration of 214° and lifts the valves 5.5 mm. This optimises gas velocity for improved low
speed torque and reduces valve train friction for improved fuel economy. For high-speed driving,
CPS switches to a cam lobe with a duration of 250° and valve-lift of 10.5 mm, allowing greater
air flow into the engine for high power. Switching is activated at 2,800 rpm at high load,
ranging to 4,500 rpm at light load conditions.
Variable Inlet Manifold optimises torque through the rev range
A new variable inlet manifold (VIM) can vary the length of its eight inlet tracts to
optimise power and torque throughout the rev range on the naturally aspirated engine. Vacuum
operated actuators open valves to select a longer, 680 mm, inlet tract at low revs, increasing
the rate of both the airflow and the engine torque. As the revs climb beyond 4,700 rpm, the
actuators select a shorter, 350 mm path allowing a greater volume of air into the engine to
optimise engine power. The actuator position is optimised by the engine control unit for
improved torque throughout the engine speed range.
Reverse cooling turns up the heat
Every component in both V8 engines has been optimised for efficiency, performance, low-end
torque and reliability. An innovative reverse-flow cooling system design has been used to
deliver thermodynamic and friction improvements. The reverse-flow cooling system pumps coolant
through the cylinder heads before flowing through the block and returning to the radiator. The
resulting cooler cylinder heads allow more optimum, knock-free, ignition timings to be used to
improve efficiency.
In addition, the 22 kW oil-to-water heat exchanger, packaged at the core of the engine,
transfers heat from the coolant to the lubricating oil during warm up, bringing the oil up to
operating temperature 14 per cent faster than the previous cooling system. This improves fuel
consumption in the crucial engine warm-up period by approximately 1%.
Reducing friction - something for nothing
Minimising internal friction is key to improving fuel consumption and CO2 emissions, and as
such was a key aim when it came to the design of the engines. As a result, the new Jaguar
AJ-V8 Gen III engines achieve another best in class, setting a new industry benchmark for
cranktrain efficiency.
All engine bearings were the subject of an extensive optimisation programme, reducing
friction without compromising reliability. Diamond-Like Carbon Coating (DLC) has been used to
reduce friction on the fuel pump tappets and a solid film lubricant has been used to coat the
piston skirts. Both V8 engines are now fitted with an electronic dipstick feature for added
peace of mind.
Unique, Jaguar sound quality
Sound quality is a key characteristic of all Jaguars and is one particular aspect that
customers relish. With that in mind, Jaguar engineers have accentuated the acoustic feedback
into the cabin in order to further enhance the driving pleasure.
The XK's exhaust sound track has been enhanced to provide a deeper and more powerful
'character' that matches the increase in torque at low revs from the new engine. At higher
engine speeds the intake acoustic feedback system combines with the exhaust system to provide
more of that unique Jaguar sound quality character.
In addition to the fully active exhaust system in which valves open to provide a more
rewarding note, the new XKR has been engineered to provide an intake feedback system to enhance
the V8 sound character commonly absent on supercharged engines. Intake manifold pressure
pulsations are fed into an acoustic filter at the rear of the engine that is tuned to provide an
edgy sports car crescendo at high revs. The filter is controlled by the engine management system,
which only allows the sound to enter the cabin under the appropriate driving conditions.
The new intake feedback system combined with the fully active exhaust system provides the most
exhilarating sound track yet delivered on a Jaguar.
New, integrated transmission completes the package
Any transmission is a major factor in delivering the performance that drivers desire, while
integrating with the engine to optimise emissions and fuel consumption. Jaguar's acclaimed
electronically controlled, six-speed ZF 6HP28 transmission offers an unparalleled combination of
driver control matched to virtually undetectable gearshifts. With control either from steering
wheel-mounted paddles or full automatic mode via the JaguarDrive SelectorTM, the new XK range
delivers exhilarating performance.
The supercharged V8 engine with 375 kW and 625 Nm of torque transmits power through an uprated
version of the ZF 6HP28, additional clutch plates and an uprated torque converter having been
added to the transmission to accommodate the extra power.
The transmission has a fully-adaptive shift system which delivers seamless gearshifts and
optimises performance and economy at all times. It also continually adapts to suit driving style,
which can vary from sporting to more economical. The 'mechatronic' control module incorporated
inside the transmission includes the software for the semi-automatic Jaguar Sequential Shift
function, selected when the driver operates either of the two steering-wheel paddles.
The high levels of torque produced by the new engines make it possible for the torque
converter lock-up feature of the transmission to be used even at low speeds, without slip. This
approach provides an additional fuel consumption benefit, contributing to the official combined
fuel economy of 12.3 l/100 km in the XKR. The advanced design of the transmission also includes
a torsional damper to absorb firing impulses from the engine, further smoothing the driveline.
The transmission is designed to be maintenance-free and the fluid is 'filled-for-life.'
Another first for Jaguar is the new Active Differential Control (ADC), the final stage of the
supercharged V8 driveline, which is designed to give improved traction and dynamic stability.
The electronically controlled differential continuously adapts to both the driver's demands
and the amount of grip available at each individual wheel. Operated by an internal electric motor
and 'ball-and-ramp' mechanism, the differential contains a multiplate clutch which transmits or
'vectors' torque to the wheel with most grip and therefore maximises the car's traction. The
multi-plate clutch assembly is designed to prevent excessive differential slip, but differs
fundamentally from a conventional traction control system, which uses the brakes to counteract
differential slip, after it has occurred.
For the first time, the new XK range introduces the innovative JaguarDrive Selector™ as its
transmission control interface. First seen on the Jaguar XF saloon, the JaguarDrive Selector™
features a rotary shift control which rises into the driver's hand as the car is started, to
give intuitive, ergonomically efficient transmission control from an extremely neat,
space-efficient interface.
The selector is, in fact, much more than just an unobtrusive yet completely practical
solution to selecting an automatic gear mode. For it also imbues the car with a strong driver
'handshake'.
Get into an XK 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.
From there, 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. And when
the engine is stopped, the JaguarDrive Selector™ returns automatically to its Park position.
Driving Dynamics
"The XK has always been an exceptional sports GT, now it has evolved into something even
more exhilarating in the form of the XKR. With huge reserves of power and torque it sets new
standards of dynamic balance, succeeding in being both very potent and rewarding yet balanced
and accessible at the same time." Mike Cross, Vehicle Integrity Chief Engineer.
The new 'handshake' of the JaguarDrive Control is a subtle reminder of the new XK range's
further enhanced sporting character and superb dynamics, that make the driving experience
exceptionally exciting and rewarding, as expected of a true sports car and a classic grand
tourer. The latest generation of Adaptive Dynamics replaces Jaguar's proven Computer Active
Technology Suspension (CATS) with an even more sophisticated solution. Active damper tuning
systems remove many of the compromises of a passive damping system - which must make a single
choice between softer damping for a comfortable ride and firmer damping for more tautly
controlled handling. CATS overcame that compromise with automatically switchable damping
modes, adapting to the road and how the car was driven. But where CATS only offered two
settings: 'soft' and 'firm', the new Adaptive Damping System in effect provides a
continuously variable damping strategy between wide extremes, benefitting ride comfort,
ultimate control handling and grip.
Its three primary functions are to control body vertical movement, roll rate and pitch
rate. One hundred times a second, Adaptive Damping analyses induced body motions and sets
each damper to an appropriate level in order to maintain a constant and level body
attitude - optimising control without compromising ride. Also one hundred times a second,
it predicts the roll rate due to steering inputs and selectively increases damping forces
to reduce the roll rate - improving handling feel and driver confidence. And one hundred
times a second, Adaptive Damping analyses fore and aft pitch rate due to throttle and
braking inputs and again varies damping forces to reduce pitch - further improving comfort
and control.
Additionally, Adaptive Dynamics improves ride quality by monitoring wheel position five
hundred times a second and automatically increasing damping rate as the suspension
approaches the limits of its travel. Similarly it controls wheel hop on uneven roads by
varying damping to move any wheel out of its natural bouncing frequency.
From the cabin, the JaguarDrive Control™ interface allows the driver to interact with
Adaptive Dynamics by selecting modes for different driving conditions and moods. In Dynamic
Mode, Adaptive Dynamics increases body control for a sportier feel. Dynamic Mode also
interacts with the management electronics to give a more responsive accelerator pedal
reaction and quicker gearshift responses.
Winter Mode was introduced on the XF and makes its first appearance in the XK range
here, adding another element of dynamic subtlety. Where Dynamic Mode offers a more sporty
feel, Winter Mode offers a more damped accelerator pedal response for progressive control
in slippery conditions, with bespoke shift settings that delay and soften gearshifts,
again for better control with low grip.
In keeping with its additional power and performance, the new XKR offers the most
sophisticated dynamic control of all, with Active Differential Control and Adaptive
Dynamics operating in tandem to offer JaguarDrive Optimisation™. This fully integrates
the functions of JaguarDrive Control™ and Adaptive Dynamics with the new Active
Differential Control (ADC) - an electronically controlled alternative to the traditional
mechanical limited-slip differential, with far more subtle control strategies.
ADC is fully automatic and can vary its locking torque (and therefore the proportion of
torque sent to each driven wheel) depending on surface conditions and power applied. Its
subtle control strategies optimise traction at each wheel, improving acceleration on
low-grip surfaces but also potentially improving stability when required.
Working with other systems such as traction control and the ABS braking function, ADC
can significantly improve overall vehicle performance, and provide more precise driving
feel.
While the less powerful XK models do not adopt the Active Differential Control of the
XKR, they do still utilise a new upgraded mechanical differential, which delivers
outstanding levels of grip and stability under power.
The Dynamic Stability Control system for the new XK range has bespoke tuning and offers
four driver-selectable modes, Normal, Winter, Trac DSC and DSC OFF, for all models. Normal
mode is ideal for everyday driving and is the default setting activated automatically on
starting.
The Winter mode - introduced for the first time on the XK range - is designed to improve
drivability and confidence in more slippery conditions. Trac DSC mode is a sportier setting
allowing the experienced driver fully to exploit the car's performance and enjoy greater
involvement in controlling it. DSC OFF allows the driver (where circumstances are
appropriate) to switch the system's electronic protection off completely, by pushing the
DSC control button for ten seconds.
Technology and driving aids
The new XK and XKR, in both coupé and convertible form, offer a number of other driver
aids that exploit the latest advanced technology. Staying faithful to its well-established
principles, Jaguar uses these technologies to empower, not to overpower the user -
enhancing driver and passenger enjoyment rather than risking high-technology 'overkill'.
Among the new XK range's practical features are intelligent front lighting incorporating
bi-xenon automatic headlamps with power wash; dynamic headlamp levelling; corner lights
that are activated by the direction indicators to improve visibility while cornering; and
standard Active Front Lighting. Standard equipment across the new XK range also includes
air sensors to optimise cabin air quality through the climate control system, keyless
entry and keyless start, cruise control, electro-chromatic fold-back exterior mirrors, and
front and rear Park Assist.
Safety
As well as the convertible's hidden, automatic roll-over protection, every car in the
new XK range features Jaguar's pedestrian deployable bonnet system. In the event of a
collision with a pedestrian, it raises the bonnet by 170 mm in just 30 milliseconds to
provide a clear space between the surface of the bonnet and the hard points underneath,
to reduce the severity particularly of head injuries while still allowing the new XK low
bonnet line. An energy absorbing bumper system also helps minimise lower leg injuries to
pedestrians.
Jaguar's Emergency Brake Assist is standard on the new XK and Advanced Emergency Brake
Assist is fitted to all models with Adaptive Cruise Control (ACC). Advanced Emergency
Brake Assist uses the ACC radar to calculate distance from and speed of approach to the
vehicle ahead and pre-charges the brake-line pressure to minimise impact speed if a
collision is predicted - with an audible warning to the driver.
For the occupant, every car in the new XK range includes front, side and thorax
airbags, incorporating new technology which reduces the load on the occupant's body if the
front airbag is deployed. Jaguar's Adaptive Restraint Technology System checks for seat
occupation and seat belt use, seat position, and the direction and severity of any impact,
and uses all that information to determine the appropriate level of airbag deployment in
any incident. Additionally, Jaguar's Protec front head restraint system protects against
whiplash in the event of a rear impact.
Stylish new wheels
The new XK range introduces new alloy wheel designs:
The new 19-inch ten-'V'-spoke Caravela wheel is standard on XK.
The twin-five-spoke 20 inch Kalimnos wheel will be standard on the XKR, while the twin
seven- spoke R Performance Nevis design is a unique option for the XKR, and an addition
to the wheel range.
With the recent addition of new options Claret, Spectrum Blue, and Kyanite Blue, the
stunning exterior colour range for the new XK and XKR is extended to 15 colours; two of
which - Salsa and Kyanite Blue - are reserved exclusively for XKR.
Equipment
In true, contemporary Jaguar fashion, a great deal of useful and intuitive technology
is controlled by the clear and elegant seven-inch Touch-screen in the centre console -
which is standard on all models. The Touch-screen provides access and control for the
Climate Control and Audio systems, for the Satellite Navigation System, for Bluetooth
mobile connectivity, and for Jaguar's Portable Audio Interface - which are all standard
equipment. The satellite navigation system offers DVD mapping. The Portable Audio
Interface offers iPod connectivity, and the connection of other storage devices through
a USB port, to the in-car sound system, with full Touch-screen control.
"The XK has always been an exceptional sports car. Now, it has evolved into
something even more exhilarating, combining Jaguar's legendary performance, new advanced
technologies and crafted luxury to create a sports car without parallel." Mike
O'Driscoll, Managing Director, Jaguar Cars.
