The 2010 XF and XFR
With the new XF we set
out to design, develop and build the definitive Jaguar sports
saloon. Now with magnificent new petrol and diesel engines,
representing the very latest in advanced power and technology, the
2010 Model Year XF is even more thrilling to drive.
Mike ODriscoll, Managing Director, Jaguar Cars
The new XF is already acclaimed as a key element in the
revitalisation of the Jaguar brand, with its new generation of
beautiful, fast cars. But now the car that newly defines Jaguar
sporting luxury is even better, with major powertrain changes and a
wider range of models including a stunning new, supercharged XFR
and a high-performance, high-efficiency diesel.
The 2010 Model Year XF available to order from January 2009
features all-new 5.0-litre direct-injection V8 petrol engines and a
new 3.0-litre V6 twin-turbo diesel with a choice of two power
outputs. There are also significant trim and specification changes
including many new features unique to the new XFR and the
introduction of new Portfolio derivatives.
New 510PS XFR sets new dynamic
When it was introduced
last year, the XF was recognised as a dramatic expression of a bold
new Jaguar design language. It also soon became apparent that here
was a car where the driving experience exceeded the expectations
created by the striking appearance. Now, the new XFR takes this
experience to new levels, shifting the balance even further towards
dynamic performance while still retaining the XFs core values as a
refined and luxurious sports saloon. Power comes from an all-new
5.0-litre direct-injection supercharged V8 engine delivering 510PS
and 625Nm of torque. Immediately recognisable, the new XFR sports a
new front-end design with revised chrome air intakes, Supercharged
bonnet louvres, four polished exhaust tailpipes, an aerodynamically
functional boot lid spoiler and side sills, unique new 20-inch
wheels and discreet R badging.
The new XFR features Active Differential Control and Adaptive
Dynamics technologies being introduced for the first time on this
and the XKR sports car. The electronically controlled differential
and suspension system work together to optimise traction under
acceleration and cornering highly appropriate for a car that
offers an electronically limited top speed of 155mph and reaches
60mph from standstill in just 4.7 seconds. The XFR also adds a
faster steering ratio and uses the XFs largest ventilated disc
brakes although every version of the XF with the new, more
powerful engines features uprated braking specification.
The new XFR is the ultimate Jaguar sports saloon. The all-new,
AJ-V8 Gen III R supercharged engine delivers a massive 510
horsepower and the advanced Active Differential Control and Adaptive
Dynamics suspension make sure that the driver can use it.
Mike ODriscoll, Managing Director, Jaguar Cars
The attributes that marked out the XF at launch are still very much
new and in the public eye. 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.
Simplicity and clever use of space are key to the XFs interior
design and this is unchanged in the new generation. For the driver,
this is centred on the compact packaging of the JaguarDrive
Selector transmission interface. The cast alloy Selector has
already gained recognition for its part in the distinctive XF
welcoming handshake; a sequence in which the illuminated
stop/start button pulsates like a heartbeat until pressed, when the
JaguarDrive Selector rises into the drivers hand and the rotating
facia vents silently open.
Features such as this have already attracted more than 30,000
customers to the new XF nine months after the start of customer
deliveries and now, in many instances, they have been enhanced
even further. The combination of aluminium dashboard, satin or gloss
wood veneers, tailored instrument panel and door panels with
twin-needle stitching as standard, plus Phosphor Blue halo
illumination and interior mood lighting, set the XFs cabin as far
apart from its competitors as its exterior styling.
Customers seeking luxury appointments should look to the new
Portfolio specification. Available with either naturally aspirated
V8 petrol, 3.0-litre V6 petrol and V6 diesel engines, the Portfolio
model includes ultimate craftsmanship details such as contrast
stitching on leather trim, Jaguar Suedecloth Premium headlining,
deep-pile carpet mats with embroidered logos, wider veneer and
colour choices and ventilated heated and cooled seats.
But it is the new powertrain options that are at the heart of the
changes for 2010 model year. The all-new 5.0-litre AJ-V8 Gen III
engines in 385PS/515Nm naturally aspirated and 510PS/625Nm
supercharged R guise add an entirely new, even more sporting
dimension to the XF range. And dont think for one moment that the
new 3.0-litre turbodiesel engines are any less impressive than the
new V8s. These new engines are Jaguars most advanced and most
efficient ever. They deliver performance at a higher level across
the board. In the case of the 5.0-litre supercharged engine,
compared to the 4.2-litre V8 that it supersedes, power has increased
by a remarkable 23 percent and torque by 12 percent.
The result in the new XFR is a 0-60mph sprint time of just 4.7
seconds (0-100kph in 4.9 seconds). More relevant in everyday
driving, an excellent indicator of XFRs great flexibility is the
time it takes to accelerate from 50-70mph just 1.9 seconds.
Two new high-performance,
The AJ-V6D Gen III
engine available in either 275PS/600Nm S or 240PS/500Nm form
sets new standards of performance and refinement for the XF diesel
customer. Featuring parallel sequential turbochargers to help
deliver the high levels of power and torque seamlessly and with
effortless flexibility, this engine is perfectly matched to Jaguars
sophisticated six-speed ZF 6HP28 automatic transmission.
The more powerful 275PS engine in the Diesel S gives the XF
outstanding levels of performance. 0-60mph is despatched in just 5.9
seconds, 1.8 seconds quicker than the 2.7-litre model it replaces.
In-gear acceleration is equally impressive, with a 50-70mph time of
just 3.2 seconds. Maximum speed is electronically limited to 155mph.
And these great performance leaps are achieved with combined average
fuel consumption in both models of 42.0mpg an improvement on the
2.7-litre engine of over 10 percent and a CO2 emissions rating of
only 179g/km. For Jaguar and the new 2010 XF, the high-performance
diesel has truly arrived.
The 240PS engine also offers new levels of performance, allowing the
XF to reach 60mph in 6.7 seconds a full second quicker than the
2.7-litre model and its 50-70mph time of just 3.7 seconds is only
fractionally slower than the 275PS Diesel S model. Maximum speed is
The comparisons for the naturally aspirated 5.0-litre V8 engine are
equally impressive. Power is increased by 29 percent and torque by
25 percent. The benchmark 0-60mph acceleration time is 5.5 seconds
(0-100kph in 5.7 seconds) some 0.8 seconds quicker than the 4.2 XF.
Better still, these improvements are achieved with comparable fuel
economy and better emissions performance. The new engines also meet
EU Stage 5 and US ULEV II/Tier 2 Bin 5 emissions regulations two
years ahead of the legislative requirement.
Dependent on market, customers will be able to order the latest
3.0-litre V6 petrol, new 275PS/600Nm 3.0-litre V6 Diesel S and
naturally aspirated V8 petrol versions of the new XF range from
January 2009. The 240PS/500Nm V6 Diesel and 510PS supercharged V8
XFR will be available to order from February 2009.
There are two new XF V6
diesels, both offering superb performance and excellent fuel
economy. The new Diesel S model sets the pace, with acceleration
from 0-60mph in less than six seconds and a maximum speed of 155mph,
and 42mpg, and CO2 emissions of 179g/km: Truly the best of both
Mike ODriscoll, Managing Director, Jaguar Cars
THE NEW 2010 XF AND XFR IN DETAIL
When the first customers
took delivery of their XFs in March of 2008, they became the owner
of a Jaguar that fuses sports car styling and performance with the
refinement, features and space of a premium luxury saloon.
And although launched only a year ago, the XF has already collected
a sizeable number of global accolades, such as the What Car? Car of
the Year and Auto Express Car of the Year in the UK, Popular
Mechanics Best Luxury Vehicle and a privileged place on Car and
Drivers 10 Best Cars for 2009 in the US. These honours are
recognition of a car that combines innovation with leading edge
design. Contemporary, individual and beautifully crafted, with
excellent performance, refined powertrains and outstanding driving
dynamics, the XF pushes the boundaries of Jaguars new design
language. It is also an unequivocally modern car that makes
intelligent use of advanced technology and as a result has
accelerated Jaguars acceptance to a much broader audience.
Now Jaguar has moved the game on again. The highlights of the new
2010 model year XF, (available to customers from March 2009,
dependent on model and market) are a new flagship the stunning,
supercharged XFR two all-new V8 petrol engines, new V6 diesel
engines and significant trim and specification changes. The new
engines are the most advanced and most efficient that Jaguar has
The new XFR is the first XF to carry the R badge, which defines
Jaguars most performance-focused models:
- Powered by a
supercharged 5.0-litre engine the AJ-V8 Gen III R developing
510PS and 625Nm of torque.
- Compared to its supercharged 4.2-litre V8 predecessor, power
has increased by 23 percent and torque has increased by 12
- The new direct-injection engine gives the XFR a 0-60mph time
of only 4.7 seconds (0-100kph in 4.9 seconds). More relevant in
everyday driving, an excellent indicator of the XFRs great
flexibility is the time it takes to accelerate from 50-70mph
just 1.9 seconds.
- This level of performance is achieved with comparable fuel
economy and better emissions than the previous 4.2-litre engine.
- The new engine also meets EU Stage 5 and US ULEV II/Tier 2 Bin
5 emissions regulations.
The new XFR and
high-performance XF diesels demonstrate Jaguars commitment to
delivering exhilarating performance and outstanding dynamics for the
driving enthusiast the Fast part of the Jaguar ethos of
designing, engineering and manufacturing Beautiful, Fast Cars.
Jaguar Design Director Ian Callum and his team have also worked to
finesse the Beautiful in Jaguars appeal:
Every XF is distinguished by its dramatic styling, flowing lines
and coupe-like appearance but the new XFR is the ultimate sporting
execution of that design language. It has superb proportions, better
than any of its rivals, with a wide track and confident stance.
Ian Callum, Director of Design, Jaguar Cars
Unique new XFR styling for
The enhanced exterior
styling of the XFR moves those sporting credentials on even further,
to deliver the ultimate expression of Jaguars new saloon car design
language - carrying a number of visual design cues that are
intrinsic to Jaguars R car philosophy. Its unique front-end
design has a larger lower grille with new black-finished mesh, plus
chrome outboard air intakes. The upper mesh grille retains XFs
bright finish, while the bonnet carries distinctive louvres, like
those on the XKR sports car.
The XFR also features bold new sill extensions, while the rear
bumper adds a unique body-coloured lower valance panel incorporating
the R signature of four large, bright-finished tail pipes. The new
bootlid spoiler has a significant aerodynamic effect. Developed in
conjunction with the new front bumper design, it further improves
the XFRs front/rear lift balance, and therefore its high-speed
stability. A new exterior mirror design also offers aerodynamic
improvements, plus improved functionality with its LED side
The XFRs sporting character is clearly apparent in the 20-inch
Nevis alloy wheels. It is the only car in its class to offer this
size of wheel as standard specification. Those twin-seven-spoke
wheels bear the wording Jaguar Supercharged embossed around their
centres, and are wrapped tightly around silver-grey brake callipers,
which carry the evocative R logo. The R badge also appears on the
right-hand side of the boot lid drop panel, to complete the XFRs
external visual identity.
The new XFR is offered with a select palette of just eight exterior
colours: Ultimate Black, Indigo, Liquid Silver, Lunar Grey,
Porcelain, Botanical Green, Kyanite Blue and Salsa. All except Salsa
and Porcelain are metallic colours and, within the XF range, Salsa
and Kyanite Blue are unique to XFR. For each colour as across the
entire XF range Jaguar suggests a Designers Choice of the
leather trim colours that best complement each body colour and the
Warm Charcoal upper facia that is standard on every XFR.
The interior design theme is modern and individual. The cabin
environment is uniquely Jaguar and in the XFR more details hint at
the cars performance. A full soft grain leather interior is
standard, with four colour choices Warm Charcoal, Warm
Charcoal/Red Zone, Warm Charcoal/London Tan, and Ivory. A new Dark
Oak veneer is the standard finish for the XFRs wood-trimmed areas.
New 18x14-way adjustable sports seats have electrically adjustable
squab bolsters for significantly improved support at higher
cornering speeds. Each XFR seat has the R logo embossed on its
squab and the front seats have leather seat-back map pockets.
The fascia introduces a unique, dark mesh aluminium finish, and
another discreet R badge on the passenger side of the instrument
panel. The speedometer and tachometer have the unique sporting
signature of red dial pointers, and carry the Supercharged motif.
And at start-up, the R logo appears on the Touch-screen as part of
the XFR driver handshake sequence.
User-friendly driver aids
The XF is a car packed
with user-friendly technologies. Features that distinguish it
include full shift-by-wire transmission controlled by the
JaguarDrive Selector; cruise control with Automatic Speed Limiter;
an optional radar-based Blind Spot Monitor that warns the driver
when there is another vehicle nearby in a different lane; and XFs
optional Rear Camera Parking Aid, which provides a clear view of the
area behind the car on the colour Touch-screen while reversing. This
is now upgraded with on-screen guidance lines that move according to
steering wheel angle to indicate the area into which the car will
A significant number of other enhancements have been made above and
beyond the impressive features in the 2008 XF:
- A new navigation
system which includes turn-by-turn instructions in the message

5.0-litre V8 that powers the new XFR is Jaguars new flagship
engine, but it is only half of the petrol engine story a
naturally-aspirated version of the all-new engine brings additional
advanced technologies and performance to other models in the XF
Generations of powerful yet refined engines have played a crucial
role over the years in establishing the unique character of Jaguar
cars. Now, two all-new direct-injection 5.0-litre V8 petrol engines
continue that tradition for the XF, delivering increased power and
torque with improved emissions and comparable fuel consumption: the
510PS AJ-V8 Gen III R supercharged and the 385PS naturally aspirated
AJ-V8 Gen III.
Light, robust and very strong
The all-new 5.0-litre V8
petrol 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, reducing the environmental impact of manufacturing
the new engine.
The new 5.0-litre V8 engines are more compact than their
predecessors. Overall engine length has been reduced by 24mm 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.
Jaguars all-new direct-injection petrol V8s have been designed
using the expertise of powertrain engineers at Jaguars product
development centre at Whitley, Coventry, UK. Malcolm Sandford,
Engine Group Chief Engineer, explains the concept behind the
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
percent and 23 percent (87PS and 94PS) on both naturally aspirated
and supercharged engines yet both meet EU5 and US ULEV2 emissions
regulations. Despite the significant increases in power, CO2
emissions of the naturally aspirated engine are the same as the
outgoing 4.2-litre V8, and the supercharged engine produces lower
CO2 emissions than its predecessor.
Direct injection power with
One of the key features
of the new petrol engines is an industry-first, centrally-mounted,
multi-hole, spray-guided fuel injection system, delivering fuel at a
pressure of up to 150bar 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 an 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 9.1:1 on the
previous 4.2-litre version to 9.5:1.
During the engine
warm-up phase, the combustion system employs multiple injection mode
strategies to deliver 50 percent 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 engines speed
The response rate of the new VCT units is 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
The naturally aspirated engine is also equipped with camshaft
profile switching (CPS) on the inlet camshaft. Depending on the
engines 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.
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, 680mm inlet tract at low revs, increasing the rate of both
the airflow and the engine torque. As the revs climb beyond 4700rpm,
the actuators select a shorter, 350mm 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.
Improved efficiency through new
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
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.
Jaguar has developed a unique, intelligent oil-pump pressure relief
valve (PRV) which senses oil pressure deep in the engines oil
galleries to control the oil pump delivery. As a result, oil pump
frictional losses are reduced during the warm-up period. New engine
oil has a lower viscosity, contributing to an extension in service
intervals from 10,000 miles to 15,000 miles or 12 months.
Both V8 engines are now fitted with an electronic oil level sensor
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
deliberately accentuated the acoustic feedback into the cabin in
order to further increase driving pleasure.
The XFR has received special attention to deliver the required V8
intake 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 tenor C, with the
output from the filter ducted into the cabin. The filter is
controlled by the engine management system which allows the
acoustics to enter the cabin only under certain conditions, such as
when the engine is accelerating hard, thus maintaining the desired
sound quality at all times.
New supercharger optimises power
A sixth-generation, twin
vortex system (TVS) supercharger is fitted to the XFRs 510PS
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 percent. 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.
Advanced six-speed transmissions
The all-new 5.0-litre
AJ-V8 Gen III and the 3.0-litre diesel AJ-V6 D Gen III engines
transmit power through an enhanced version of Jaguars acclaimed ZF
6HP28 electronically controlled, six-speed transmission. Additional
clutch plates and an uprated torque converter have been added for
the supercharged V8 to facilitate the extra power.
The transmission has a fully-adaptive shift system which delivers
extremely smooth gear changes and optimises performance and economy
at all times. The Jaguar Sequential Shift suffers no torque
interrupt resulting in a smoother more powerful shift feel and an
almost instantaneous shift from the time the driver touches the
shift paddle to the completion of the shift event. 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 competitive fuel consumption, contributing to the
official combined fuel economy of 22.5mpg (12.5l/100km) in the XFR
and 25.4mpg (11.1l/100km) in the naturally aspirated V8-powered XF.
The advanced design of the transmission 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.
The headline advances
made by Jaguars new engines are hugely significant and impressive.
They take Jaguars philosophy of intelligent power to another new
level and that means instant responses, seamless power and smooth,
refined performance with comparable fuel economy and better
emissions all thanks to intelligent use of the most advanced
technologies. And, of course, in XFR guise, it makes for the
quickest XF yet.
Mike Cross, Chief Engineer, Vehicle Integrity, explains the
significance of the powertrain changes in the 2010 XF range:
Instant response, seamless power delivery and smooth refined
performance characterise the new XF diesel and V8 petrol engines.
The awesome 510PS supercharged V8 engine in the XFR delivers
thrilling performance to satisfy the most demanding drivers.
Allied to a class-leading automatic transmission featuring Jaguars
lightning-quick Sequential Shift system and advanced technologies
such as the new Active Differential Control and Adaptive Dynamics,
the XFR offers an exhilarating driving experience, yet one that is
still accessible to everyone.
In line with the additional performance, XFR adopts the largest
brakes fitted to the XF range, with 380mm diameter internally
ventilated front discs. XFRs unique 20-inch wheels and tyres were
specifically chosen to enhance the dynamic character of the car, and
in particular to optimise wet weather grip.
Jaguars Emergency Brake Assist is standard on XF and Adaptive
Cruise Control (ACC) is now available as an option all models.
Advanced Emergency Brake Assist is a new attribute of the ACC system
on the new 3.0 V6 diesel and 5.0 V8 petrol models; it 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 as well as giving an
audible warning to the driver.
To improve handling and steering responses, the XFR is fitted with a
fast ratio steering rack, and additionally benefits from the
further improved front-to-rear aerodynamic balance offered by a new
boot lid spoiler and deeper front bumper. This is a significant gain
as XFs lift balance was already best in class, and its low overall
aerodynamic drag coefficient of only 0.29Cd contributes to both low
wind noise and inherent high-speed stability.
The XFs body shell is already extremely stiff - in fact the
stiffest in its class. This is key to the XF delivering superb ride
and handling based on taut body control and precise, responsive
steering. The bodyshell for the new XF 2010 Model Year is even
stiffer, thanks to a new rear subframe and the adoption of a boot
cross-brace that was previously only fitted to the XF SV8
suspension and differential
The biggest changes in
chassis dynamics for the XFR, however, come from two new advanced
technologies, Adaptive Dynamics and Active Differential Control,
which are both incorporated as standard.
Active Differential Control (ADC) with traction-only functionality
and handling functionality is an electronically controlled
alternative to the traditional, wholly mechanical differential,
offering more subtle control strategies.
ADC can vary its locking torque (and therefore the proportion of
torque to each driven rear wheel) depending on surface conditions
and power applied. Its control strategies optimise traction at each
wheel, improving acceleration on low-grip surfaces while also
enhancing cornering ability.
ADC has no adverse effect on either refinement or stability where
the traditional, mechanical differential can compromise stability
under hard applications of power, demanding more corrective input
from the driver.
Whereas a mechanical differential is a permanently active part of
the drivetrain, the XFRs new ADC system is switched off when not
required, so does not create undesirable understeer and creates no
issues with NVH at lower speeds.
The differential is operated by an internal electric motor and
ball-and-ramp mechanism, and contains a multiplate clutch, which
transmits or vectors torque to the wheel with most grip. The
multi-plate clutch assembly is designed to prevent excessive
differential slip, but differs fundamentally from a conventional
traction control which uses the brakes to counteract slip after it
Continuously variable damping
Adaptive Dynamics, which
replaces Jaguars proven Computer Active Technology Suspension
(CATS) on the XFR, is a highly sophisticated active damping system
which automatically adjusts suspension damper settings to suit both
road conditions and the way in which the car is being driven. By
removing the need for compromise between a fixed, softer setting for
ride comfort and a fixed, firmer setting for tauter body control and
handling, Adaptive Dynamics allows the balance between ride and
handling to be optimised whatever the circumstances. Unlike earlier
systems with only a small number of steps in the damper settings, it
offers a progressively variable damping strategy between wide
extremes, to deliver a comfortable but sporty ride with impressively
The three primary functions of Adaptive Dynamics are to control
vertical movement, roll rate and pitch rate of the body. It does
this by analysing induced body motions one hundred times a second,
and setting each damper to an appropriate level in order to maintain
a constant and level body attitude, thereby 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 that roll-rate improving feel
and driver confidence as well as analysing 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 by monitoring wheel
position 500 times a second and automatically increasing damping
rate as the suspension approaches the limits of its travel.
Similarly, it controls wheel hop by varying damping to move any
wheel out of a natural bouncing frequency, again benefiting ride
comfort, handling, and even grip.
XFR also features Handling Functionality, which is unique in this
class. In conjunction with the DSC Off option and JaguarDrive
Control with Dynamic Mode, this supplements all the advantages of
Traction Only Functionality with a number of more driver-focused
dynamic characteristics. When selected, Dynamic Mode (which is also
standard on the new naturally aspirated 5.0-litre V8 petrol and new
3.0-litre V6 diesel models) modifies the throttle, stability and
transmission parameters, and on XFR only it also modifies the
Adaptive Dynamics responses. The combination of ADC and Dynamic mode
with DSC Off allows controllable power-on oversteer, and improves
off-throttle stability, allowing quicker, more spirited cornering.
It can also improve stability in situations such as an emergency
lane-change manoeuvre at high speed and, in combination with DSC,
reduce the brake interventions which the more enthusiastic driver
might see as intrusive.
So, working with DSC, the TCS traction control system and ABS
braking function, ADC can significantly improve overall vehicle
performance, and provide even more precise driving feel. Together
with its very high performance potential, that is what defines the
new XFR as a perfect home for Jaguars R philosophy, and the
sportiest of all XF models.

Two new 3.0-litre
parallel sequential twin-turbo commonrail diesels, producing either
240PS or for the Diesel S version 275PS, are added to the XF engine
range. The new AJ-V6D Gen III engines will cut Jaguars CO2
footprint while setting new benchmarks in their respective classes.
Both engines exemplify Jaguars reputation for innovation and
engineering excellence; exhaustive attention to detail and the
introduction of new cutting- edge technologies having produced
powerplants of unparalleled performance and efficiency.
The 275PS, 600Nm engine invigorates the XFs acceleration and top
speed, with the 0-60mph time reduced to just 5.9 seconds, a 50-70mph
time of just 3.2 seconds and an electronically governed top speed of
155mph. The 240PS, 500Nm version also improves on the previous
2.7-litre model with a 0-60mph time of 6.7 seconds, a 50-70mph time
of just 3.7 seconds (only half a second slower than the 275PS Diesel
S model) and a top speed of 149mph.
The new parallel sequential turbocharger system on our new V6
diesels delivers V8 levels of performance from very low revs. The
engines can deliver 500Nm torque from standstill in just 500
milliseconds, which is a remarkable achievement. Its a power unit
that delivers superb flexibility and remarkably low fuel consumption
and emissions, while building on the refinement that has become a
trademark of our Jaguar diesel engines.
Group Chief Engineer, Powertrain, Ron Lee.
Drawing on the considerable experience gained in designing the
original, acclaimed 2.7-litre engine, the new 3.0-litre V6 diesels
demonstrate that it is possible to deliver improved performance,
while reducing CO2 emissions. In the XF, the new engine produces 12
percent less CO2 than the 2.7-litre while power has increased by 33
percent in Diesel S guise. As well as tackling CO2, the new
3.0-litre meets the forthcoming EU5 regulations, due to come into
force at the start of 2011. And these great performance leaps are
achieved with combined average fuel consumption in both models of
42.0mpg an improvement on the 2.7-litre engine of more than 10
Twin-turbos - maximum efficiency,
A key feature of the new
engine is the unique, parallel sequential turbocharger system, the
first of its type to be fitted to a V-engine anywhere in the world.
Delivering high torque throughout the entire engine rev range,
improved throttle response and low CO2 emissions, the
twin-turbochargers work sequentially to deliver unrivalled response
and best-in-class torque at low engine speeds, while packing a huge
punch at higher engine speeds.
For most day-to-day driving, including motorway cruising, a
responsive, variable-geometry primary turbocharger does all the work
while the smaller, fixed-geometry, secondary turbo is dormant,
saving energy and improving efficiency. When the engine revs climb
above 2800rpm, the secondary turbo is brought on line within 300
milliseconds, smoothly and seamlessly boosting the engine output
with no discernible turbo-lag or power-step.
Driving a turbocharger requires pressure from the exhaust, creating
pumping losses in the engine and increasing fuel consumption. To
alleviate this, valves under the control of the engine management
system isolate the secondary turbocharger both from the exhaust
stream and the engine inlet tract when it is not required.
Some twin-turbo systems rely on a smaller turbo for primary use,
only using a larger turbo when higher power is required. Though
effective, this has the disadvantage of raised exhaust pressure and
increased pumping losses. The system in the new XF uses a larger,
variable-geometry turbocharger more of the time, which not only
reduces pumping losses, but also improves fuel consumption and CO2
emissions. Jaguar engineers have particularly focussed on the issue
of turbocharger lag at low engine speeds. The new AJ-V6D Gen III
3.0-litre diesel significantly out-performs its rivals in this
respect by delivering 500Nm of torque in only 500 milliseconds from
A new commonrail
fuel-injection system delivers up to five diesel injections on each
cycle at a pressure of 2000bar. Each injector tip is perforated by
seven holes through which finely atomised fuel is sprayed into the
cylinders. The high-pressure injection increases power, improves
economy and reduces both CO2 and particulate emissions. New,
third-generation high-speed piezo injectors allow up to five precise
injection events during each combustion cycle, minimising engine
Piezo crystal packs operate each injector by expanding when an
electric current is passed through them. They react virtually
instantaneously but can make a distinctive click when fired, which
can add to diesel engine noise at idle. This doesnt happen with the
new AJ-V6D Gen III : the crystals in Jaguars new injectors are
fitted nearer to the tip meaning they are mounted deeper inside the
engine, providing better sound insulation and quieter operation.
Another new feature of the third-generation fuel-injection system is
the metering mode. Traditional diesel commonrail fuel pumps
oversupply the injectors, with the surplus being returned to the
fuel tank. During this process, fuel temperature increases and
cooling it again consumes considerable amounts of energy. In
metering mode, the pump delivers fuel to the injectors only at the
rate required. Consequentially, there is no rise in fuel temperature
and no wasted energy.
Compact, light and clean
The two cylinder heads,
with four valves per cylinder, are made from aluminium and the
cylinder block is made from compact graphite iron (CGI). The higher
tensile strength of CGI makes it possible to cast a smaller block;
some 80mm shorter than a conventional grey cast iron equivalent.
The new, water-cooled, exhaust gas recirculation system (EGR)
important for reducing pumping losses and emissions of NOx in a
diesel engine is more efficient than the 2.7-litre unit. The
valves that allow exhaust gas into the system are located on the
hot side of the engine nearest the exhaust manifolds; these valves
never cool while the engine is running, so there is no condensation
of combustion deposits which occurs on engines fitted with cold
side valves, hence the EGR system always works at maximum
efficiency. Since the EGR cooling is so effective, exhaust gasses
can bypass the system and return to the exhaust pipes, allowing
faster warm-up from start-up and reducing emissions still further.
EU5 emissions regulations have been achieved ahead of the 2011
legislative timetable using conventional diesel oxidation catalysts
and diesel particulate filters (DPFs). NOx levels are reduced at
source through the combustion system design, the addition of the new
commonrail injection system and the new EGR system with by-pass. As
a result, specialised NOx exhaust after-treatment is unnecessary,
avoiding the need to use additional precious metals in the exhaust
Remarkably quiet for a diesel
The CGI cylinder block
and new piezo injector design reduce combustion noise in the new
engine. Multiple, precise injections of fuel on the combustion
stroke also reduce combustion noise and all engine covers including
camshaft covers, front covers and the sump have been optimised to
subdue radiated noise.
Engine enclosures have been ribbed to minimise radiated noise and
the sump pan is manufactured from sound deadening steel (SDS),
comprising a polymer layer sandwiched between two layers of steel.
Internal friction, a major contributor to unnecessary fuel
consumption, has been addressed by careful optimisation of the
crankshaft, valves and pistons. All these features combine to make
the new Jaguar AJ-V6D Gen III engines amongst the quietest premium
diesels on the market today.
A major step forward
In summary, with its
parallel sequential turbocharger system, third-generation common
rail fuel injection system and fully optimised EGR system, the new
3.0-litre AJ-V6D Gen III diesel excels when it comes to power,
response and refinement in the premium diesel segment.
The fact that weve reduced CO2 emissions to 179g/km with this
engine highlights the class-leading fuel economy customers can
expect, combined with fantastic performance. Its another great
example of Jaguar delivering unrivalled performance while at the
same time taking the level of refinement in diesel engines to a
whole new level.
