SPORTKU.COM - Kelahiran Ford Fiesta R2 di kancah rally internasional merupakan sebuah terobosan baru demi berkembangnya dunia rally.
Fiesta
R2 merupakan sebuah spek mobil Ford yang dipertandingkan di berbagai
macam rally tingkat dunia. Mobil yang masuk kedalam Grup R ini merupakan
pengembangan produk parts dari perusahaan Inggris yang bernama M-Sport.
Perusahaan ini mengembangkan produk parts rally untuk Ford dan
juga memiliki berbagai macam program rally dan edukasi yang berhubungan
dengan mobil rally bermerek Ford.
R2
merupakan mobil rakitan pertama M-Sport yang memiliki standarisasi
regulasi di seluruh rally dunia (Grup R). Ford Fiesta R2 - Developed by
M-Sport UK
Ide
dari pengembangan Ford Fiesta R2 ini adalah menciptakan mobil rally
yang ekonomis, dan dijual secara global dengan spek yang sama, sehingga
dapat dipertandingkan di berbagai macam negara.
Kesamaan
pada spek tersebut dapat terjadi karena setiap orang yang ingin
berkompetisi di kelas ini harus menggunakan Ford Fiesta S dengan rally
conversion kit yang sama. Yaitu rally conversion kit yang dikembangkan
oleh M-Sport di Inggris.

Rally
conversion kit dari M-Sport ini dijual seharga $30.000. Kit tersebut
dapat menjadikan Ford Fiesta S yang kita miliki menjadi legal untuk
dipertandingkan di Grup R. Beberapa parts yang didapat antara lain
seperti upgrade pistons, conrods, camshafts, injectors.
Sementara
pada sektor transmisi adalah penggantian girboks model standar dengan
model sequential 5 kecepatan. Dan pada sektor suspensi seperti
penggantian sokbreker standar dengan Reiger beserta coil springs dari
Eibach.

Ford dengan spek ini akan menjadi balapan yang sangat mendunia dan
digandrungi para pecinta rally.

Chris Williams, the M-Sport’s Principal Engineer in charge
of the R2 development, explained, “The Group N regulations that we had
to apply to the Fiesta ST meant that the car had to be production based
with the necessary compromises that this inherently produced. The
production engineers designing the ST road car had a myriad of criteria
to fulfil: noise, vibration, emissions, as well as performance and
handling. The R2 regulations, however, allow us to vary the standard
mechanism and to ‘cherry pick’ components from the manufacturer’s
portfolio in order to optimise the competition benefits.”
EngineThe
engine is a 1.6 Zetec 16V 1598cc Ti-VCT with four cylinders in line,
DOHC, 16 valves, alloy cylinder head and block with variable cam timing.
The sump has been modified and the car now has bespoke engine mount
bracketry welded to the bodyshell. “The engine mount on the right-hand
side is machined aluminium, while the gearbox mount on the left is cast
into the gearbox casing, resulting in lightweight, stronger and more
cost-effective engine mounts,” explained Williams.
The engine
conversion kit consists of pistons, conrods, camshafts, valve springs,
injectors, an airbox, air filter, spark plugs and a sump baffle kit.
The engine delivers 163 PS @ 7,500 rpm and torque of 182 Nm @ 5,700 rpm.
SuspensionThe
suspension comprises of Reiger adjustable dampers with Eibach springs,
spherical jointed top mounts front and rear. The front dampers are
adjustable for bump and rebound. Competitors will have the ability to
adjust the geometry by use of camber washers on the front, a similar
system to recent Ford Focus WRC cars. The rear suspension beam is taken
from the standard car, but has uprated mounts.
The R2 has a
two-bolt clamped front upright rather than the spigot fit of the Fiesta
ST. Williams explained, “The R2 will have an adaptor pin securely
mounted in the upright and a spherical bearing connecting the lower arm,
as opposed to a ball joint. We use standard uprights and, to increase
the safety margin and clamping force, we will use a five stud hub rather
than four stud.”
BrakesThe
standard front brake callipers have been removed and replaced with
lightweight four piston competition callipers. The servo has been
removed to give improved pedal feel. The Group R regulations mean that
the brake lines can be simplified to a standard H-pattern with a bias
valve adjuster rather than the dual circuit and pattern of the Fiesta
ST. The AP brake discs are 285mm (gravel) and 310mm (Tarmac) and they
share a common calliper.
The standard drum brakes have been removed
and replaced with Ford Focus derived AP rear discs (280mm) and single
piston callipers. An upright hydraulic handbrake is included in the
standard kit, not as an option this time around.
BodyshellUnlike
Group N regulations, the R2 rules permit the removal of superfluous
panels and brackets. “This allows a considerable weight saving,”
explained Williams. “We expect to be bang on the class weight of 1030kg,
which is a good saving when compared with the Fiesta ST.” Jacking
points are included and seam welding is permitted on the bodyshell.
Rollcage“We’re
using a T45 multipoint rollcage, which is lighter and considerably
stiffer than the Fiesta ST rollcage. The door bars are the same size,
design and material as currently used in the Ford Focus RS WRC, which is
an improved safety feature,” said Williams. The rollcage picks up on
suspension points, the seat position is optimised and an integrated dash
bar has been incorporated to create additional strength. 35 meters of
T45 is used to build the rollcage, which will be supplied in kit form
and must be fitted by an ASN approved centre.
Body Protection“The
R2 sumpguard is lighter and stiffer than the one used in the Fiesta ST.
The composite tankguard – a positive feature on the ST – has been
carried over into the R2 design,” explained Williams.
TransmissionThe
R2 employs a five speed sequential gearbox developed by Sadev with
plated limited slip differential and uprated driveshafts. A bespoke
gearbox casing has been developed specifically for the Fiesta R2. The
gear linkage is very simple, running a straight rod with spherical
joints. “The driveshafts have been uprated throughout.
The tripod
design has been carried over from the series production car and is
significantly bigger than that used in the Fiesta ST, thereby increasing
the strength of the R2,” said Williams. The clutch has been uprated and
the Pi Research engineered ECU has a flat shift feature with full
throttle closed loop control shift.
Exhaust System and ManifoldThe
stainless steel exhaust system and manifold is TIG welded and
manufactured by Pankl. A FIA homologated catalyst is included in the
system, which is designed to comply with a work limit of 98 dBa at 4,500
rpm.
InteriorSparco
ADV seats with side-impact head restraints are included in the R2
standard kit, with six-point Sparco seatbelts and quick release buckles.
“Replacement door cards will also come as standard and have been
specifically designed to be lightweight and to fit with the rollcage,”
concluded Williams.
ElectricalThe
R2 has an overlay loom for all auxiliary controls. It also features a
Ford Power button to start car and an electrical fire system.
