Ford's latest hot-hatch, the Fiesta XR4, will
deliver an exciting new sports performance option for small-car enthusiasts when
it goes on sale this month.
Engineered in Germany and offering European styling and
superb driving dynamics, the feature-laden Fiesta XR4 will have a recommended
retail price of $24,990*.
"Fiesta XR4 will become the benchmark in the
light car hot-hatch segment, as it boasts a specially modified 2.0-litre engine,
numerous safety and sports enhancements and an eye-catching appearance," said
President of Ford Australia, Tom Gorman.
"It is a sexy, new and fun to drive car
deserving of Ford Australia's XR nomenclature, a badge which promises to deliver
a special performance orientated vehicle."
Ford dealers have reported strong pre-sale
interest in Fiesta XR4 following its rave reception at the Melbourne
International Motor Show.
"Such anticipation is not surprising as Fiesta
XR4 is engineered by Ford’s TeamRS, the same organisation responsible for the
stunning Focus XR5 Turbo," said Mr Gorman.
"Fiesta XR4 is a vehicle designed with the
passionate driving enthusiast in mind and delivers another performance offering
to Ford customers. The eagerly awaited new model is sure to become a showroom
sell-out."

MECHANICAL
Fiesta XR4 is powered by a specially modified
version of Ford’s 2.0-litre Duratec 16-valve engine, the same engine that powers
the Focus.
"The 2.0-litre Duratec engine characteristics
are ideally suited to the performance Fiesta as it combines free-revving
performance and impressive low-end torque for excellent all-round driveability,"
said Director of TeamRS, Jost Capito.
"It delivers a wide spread of torque for
flexibility and pulling power."
The engine has undergone performance
enhancements which see it develop 110kW at 6000 rpm, compared with the 107kW at
6000 rpm when installed in the Focus. The increased output is the result of an
all-new, low-loss intake system and new sports exhaust system developed
specifically for the Fiesta XR4.
Maximum torque of 190Nm is increased from 185Nm
in the Focus and the torque delivery is of an exceptionally wide spread, with 80
per cent of peak torque available from as low as 1500 rpm and more than 90 per
cent from 2200 rpm all the way to 6150 rpm.
Fiesta’s Durashift five-speed manual
transmission has been extensively modified to suit its application in the new
model and in keeping with its sports-performance underpinnings, Fiesta XR4 is
only available with a manual transmission.
A short-throw gearshift is fitted to allow
quick, accurate shifting, all the gear ratios have been changed and the first,
second and third gearsets have been shot-peened for extra strength.
New variable intake system
The Duratec’s sophisticated variable intake
system (VIS) is the secret to the Fiesta XR4's impressive spread of torque. This
system uses gas dynamic effects in the engine’s intake system to tune its
performance through variable intake runner lengths. This technology improves the
gas-dynamics inside the intake system.
The Duratec’s VIS intake manifold achieves this
by using butterfly valves in the runners. These valves are operated by a vacuum
motor and split the runners into a longer part and a shorter part.
They are closed at low rpm to give a long
runner length and are opened at high rpm to join all the runners to a common air
chamber, which sets up a standing wave effectively to generate a shorter runner.
The lightweight, all aluminium alloy
construction of the Duratec engine is the key to its successful installation in
the Fiesta.
The Duratec engine has a gravity sand-cast
cylinder block with cast-iron cylinder sleeves cast directly into the block. An
aluminium alloy ladder frame structure, which carries the bottom crankshaft
bearing races, and a ribbed aluminium oil pan contribute further to stiffness.
The aluminium alloy cylinder head has an
asymmetrical four-valves-per-cylinder layout with twin overhead camshafts driven
by a silent chain drive.
Tailored installation
In addition to the new exhaust system,
considerable amounts of detailed engineering work have been done by TeamRS to
install the larger power unit into Fiesta XR4’s engine compartment.
The engine, which is inclined backwards at six
degrees, mates to the Durashift transmission with a new clutch housing. Its belt
driven auxiliaries have been re-positioned with a rear mounted alternator and
front mounted air conditioning pump.
A low inertia flywheel has also been fitted to
provide faster throttle response. The Fiesta XR4 exhaust system incorporates a
revised catalyst for reduced back pressure, while a great deal of tuning work
has been done to give the engine a suitably sporty note.
Rewarding Chassis
The TeamRS target for Fiesta XR4 was to create
a fun to drive, rewarding and safe handling car. After nearly two years of
development work, on every sort of road from twisty English country lanes to the
famous Nürbürgring Nordschleife race track, the team’s engineers feel they have
more than achieved their objectives.
The Fiesta range was engineered from the start
with a chassis intended to provide high standards of driving quality, inspired
by the class-leading dynamics of Focus and augmented with a dash of small car
fun.
An exceptionally rigid body structure with
ultra-stiff mounting points for the suspension and steering was the solid
foundation for the team’s work.
A rigid front sub-frame carries the MacPherson
strut front suspension and steering system, while the Fiesta's rear suspension
is a twist-beam system that provides accurate control of wheel geometry, has
strong lateral stiffness to aid handling and good longitudinal compliance for
ride comfort.
All these qualities enabled TeamRS to develop
the Fiesta XR4 without the need for any structural changes to the Fiesta’s core
suspension layout.
"The latest generation Fiesta is solid as a
rock. It was the ideal basis for a performance derivative," said Mr Capito.
"Fiesta XR4 builds on that quality and we
believe it extends the strengths of Fiesta as the unquestioned dynamics leader
in the segment."
Developed for handling and
grip
The XR4’s handling set-up has been tailored to
reward the enthusiast driver and at the same time enabling relaxed driving.
"What I am particularly proud of is that we
have achieved its high standards of handling and grip while keeping a really
good ride quality," said Mr Capito.
The XR4 front springs have also been
considerably stiffened from 16.5N/mm of the standard car to 24N/mm, and the
dampers have been recalibrated. A revised design for the front suspension
knuckle provides more negative camber to the front suspension to generate more
front end grip.
The rear springs also have been stiffened, from
15N/mm to 17 N/mm, and the dampers modified to suit the XR4. The twist beam axle
has also been stiffened from 520 Nm/degree on the standard Fiesta to 720 Nm/deg.
The steering rack ratio for Fiesta XR4 has been
shortened by 10 per cent and the toe-in reduced, to make the steering more agile
whilst maintaining high speed stability and controllability.
The front sub-frame has been stiffened to
enhance suspension control and to create an even more precise steering feel.
Fiesta brakes have been upgraded to match the
performance of Fiesta XR4. The 278mm x 22mm front ventilated discs have been
fitted with larger calipers and pads.
At the rear, XR4 also features the first time
fitment of disc brakes to any Fiesta model. Additionally, the brake system has
been tuned for optimum response, achieving good initial bite followed by firm,
progressive stopping performance as a result of fine tuning of the brake
booster.
SAFETY
Safety specification in the Fiesta XR4 is in
keeping with its performance car credentials – very impressive. This includes
driver and front passenger airbags, side curtain airbags and side thorax
airbags.
Standard fitment driver aids consist of Dynamic
Stability Control (DSC), traction control and ABS with Electronic Brakeforce
Distribution (EBD). Sports suspension, a passive anti-theft system and remote
central locking complete the package.
DSC tuned to complement the
XR4
Ford’s Dynamic Stability Control (DSC) and
traction control systems are fitted as standard on Fiesta XR4. The DSC system
has been specially calibrated by TeamRS chassis engineers, allowing the
enthusiast driver to exploit fully the fun to drive nature of XR4 within the
safety net of the system parameters, without the feeling of being restricted by
the system.
In order to encourage use of the fun to drive
aspects of Fiesta XR4 and fully utilise its chassis dynamics, the system’s
oversteer control has also evolved. The result is a DSC calibration that, even
under track conditions, the performance driver enjoys exploiting.
DSC uses the individual wheel speed sensors of
the ABS system together with yaw rate, steering input and lateral acceleration
sensors to constantly monitor the car’s dynamic behaviour and compare it to the
driver’s inputs.
If the system detects imbalances, it first uses
the traction control system to reduce engine power and prevent loss of traction.
If it detects understeer, DSC provides a braking impulse to the inside rear
wheel to stabilise the car. If it detects oversteer, a braking impulse to the
offside front wheel has a similar effect.
Tyre choice has been a crucial part of
development and TeamRS engineers worked closely with Pirelli to develop a
special version of the high performance P Zero Nero tyre.
The P Zero Nero has an asymmetric tread pattern
with longitudinal channels to disperse water, optimised for position and size.
The central strip is made up of continuous semi-slick elements to increase
rigidity and improve directional precision whilst avoiding wheel slip during
acceleration.
Fiesta XR4 comes with a low profile 205/40 ZR17
tyre, wrapped around a unique multi-spoke alloy rim.
During the development process of the Fiesta
XR4, a great deal of time and effort was spent ‘balancing’ the controls to
create harmony between the feel and response of the brakes, clutch, steering and
gearshift functions.
As a result all these controls display a
performance feel and are a coherent part of the car, while also having that
essential sporty Ford feel which enthusiasts recognise and appreciate.
EXTERIOR APPEARANCE
The Fiesta XR4 is based on the three-door
Fiesta model which, unusually among cars in its class, already has its own
distinctively sporty appearance compared with its five-door counterparts. To
achieve this, the three-door features a more sloping roofline and steeper angled
tailgate, creating a youthful and lively look.
Fiesta XR4 develops this further and adds a
strong performance flavour. At the front a new, XR5 Turbo-style bumper and air
dam moulding features a deeper, sportier version of Fiesta’s hallmark
trapezoidal grille. Situated either side of the grille are circular
chrome-ringed front fog lamps.
The grille opening has been tailored for
optimum engine breathing and the small lip spoiler under the front air dam is
the result of detailed aerodynamic tuning.
Subtle side skirts carry the lower body line of
Fiesta XR4 through from the front bumper to the rear, where there is a matching,
deeper new bumper moulding. This has a large air diffuser opening and, like the
front bumper, has its lower section finished in a charcoal grey colour.
To complete the detailing, the exhaust tail
pipe is finished with a half-round section, polished metal trim as it exits the
bumper.
A rear roof spoiler has been fitted, with the
gap between it and the roof having been carefully tuned for optimum
aerodynamics, thereby reducing drag and improving downforce.
New body side mouldings angle down towards the
front end of the car and further emphasise the performance stance of the Fiesta
XR4. Body side mouldings, door handles and newly designed door mirrors, powered
and heated, are all body coloured.
The whole effect is complemented by the lowered
suspension, low profile Pirelli P Zero tyres and large, arch-filling alloy
wheels. These alloys were specially developed for the car and their look is
another styling element that establishes the XR4 brand in the hierarchy of
performance Fords.
INTERIOR ENVIRONMENT
Inside, Fiesta XR4 has been designed both to
look good and to create the driving environment an enthusiast driver demands.
The special sports seats have been developed
carefully to give maximum support to drivers of different sizes and builds. At
the same time they have retained the excellent everyday comfort required of a
Fiesta variant.
The front seats themselves are trimmed in black
leather with central cloth sections finished in either red or blue, depending on
exterior body colour.
Fiesta’s ergonomically excellent driving
position is given the special XR4 treatment with a thick, leather-wrapped
steering wheel that has a bright steering wheel spoke design, metal pedals and a
leather wrap gear knob. It all creates a ‘cockpit’ that will not just look the
part but will also be supremely functional.
Special XR4 interior detailing includes matt
finish rings around the instruments themselves, added brightwork on the
handbrake and door pull handles, and alloy ‘XR4’ scuff plates on the door sills.
Vehicles with an exterior colour of Performance
Blue or Frozen White will feature a blue instrument panel, while all other
examples will offer white on black instrument graphics.
"These elements are details the more
enthusiastic driver looks for in a sporty car, the ‘jewels’ that advertise
elegantly that you’re inside something special," said Mr Capito.
COLOUR AND TRIMS
The new Fiesta XR4 will come in six exterior
colours, all available with an optional overhead stripe combination.
The colour palette is Colorado Red, Frozen
White, Moondust Silver, Sea Grey, Panther Black and Performance Blue. There are
three different optional overhead stripe colours available, being silver, blue
or white, depending on the exterior colour chosen.
"The overhead stripe is a signature feature
unique to Fiesta XR4 and the bold twin stripes create an eye catching
appearance, which alludes to the performance intent of the new vehicle," said Mr
Capito.
"Fiesta XR4 in Frozen White with the overhead
blue stripes delivers the classic sports appearance, very reminiscent of the
famous original Ford GT."
PRICING AND SPECIFICATION
Fiesta XR4 will be available for sale in June
with a recommended retail price of $24,990*.
After the initial launch period supply will be
limited to 40 units per month, ensuring the exclusivity of the new model is
retained.
"Fiesta XR4 will become a cult car, much in the
same genre as Focus XR5 Turbo," said Mr Capito.
"European styling and German engineering
evident in Fiesta models, mated with the technical and sports-performance
expertise of TeamRS, have combined to produce an absolutely fantastic vehicle.
"Fiesta XR4 is an invigorating vehicle which
rewards enthusiastic drivers, yet still retains road-handling manners and
refinement that ensures it is just as enjoyable to drive every day."
