THE NEWEST BENCHMARK

In addition to its involvement in the WRC in which

Citron Racing has wonsix FIA Manufacturers

World Championship titles, the company has

always made cars for sale to its clients. The

Citron DS3 R3 has been designed with this in mind.

The car is a good all-rounder, quick and accessible,

and the DS3 R3 is already considered a benchmark

in its category.

The DS3 R3 is built to comply with the FIA R3T

regulations; it uses the configuration of, and looks

like the series production model. The original steel

monocoque has been reinforced by a welded

multipoint rollcagethat ensures the rigidity of the

chassis and the safety of the crew.

Under the bonnet is the 1.6-litre 4-cylinder THP

(high pressure turbo) engine developed from the

PSA series production version. The use of specific

parts for competition (air box, camshafts, pistons, con

rods, exhausts, turbo and electronic management)has increased the power output to 210 bhp.

Besides the sheer power, the engineers have made

a big effort to find more torqueto provide better

traction, which makes driving more fun. The DS3

R3 engine is delivered assembled, run in and

bench tested.

The expertise acquired by Citron Racing in the World

Rally Championship has been applied to the DS3

R3. The car has semi-automatic gear selection

on the 6-speed sequential gearbox. This device

makes gear changing twice as quick as on a normal

mechanical box, while improving the reliability of the

power train.

The suspension has been designed for use on all

kinds of terrain from rough gravel to asphalt, and it

uses the most up-to-date technology.There are

several setup adjustments available, so the DS3 R3

can be adapted all kinds of driving styles. Citron

Racing recommends Pirelli tyres.

The DS3 R3 is sold on the basis of series production

parts and specific racing components as a kit or ready

to race. A gravel kit including suspension, front

brake discs and additional underbody protection is

also available.

Toujours avec lobjectif doptimiserla rpartition des masses, la batterie et

lextincteur automatique sont placs derrire lessiges. Conservant lemplacement dorigine, lerservoir souple est enferm dans un caisson enmatriau composite. Il est quip dun systme deremplissage de carburant aux normes FIA. DS3R3 peut embarquer deux roues de secours: lapremire sous la croix darceau et la seconde dansle panier dorigine.

RIGIDITY ANDSAFETY

The DS3 R3 takes advantage of Citron

Racings know-how in passive safety and chassis

rigidity. Unnecessary original supports have

been removed from the series production

monocoque, which is then rewelded beforea multipoint rollcage is installed . The cage

is built industrially and pre-assembled outside the

car to guarantee the quality of the weld before it is

installed. The monocoques are delivered equipped

with all the supports and fixations requiredfor

assembling the car.

The crews position has been studied to combine

ergonomics, safety and performance. The bucket

seats are placed as near as possible to the

central tunnel, which improves weight distribution

and protection in case of side impact . With

this in mind, panels in impact absorbing foamcomplying with the WRC standards are fitted in the

doors. The drivers seat is further forward than on the

series production version to give him better visibility.

The driving position can also be adjusted for

all heights thanks to several settings: position of the

pedal box, height and depth of the steering wheel,

depth of the gear changing paddles and positions of

the hand brake and the seat frame.

The battery and fire extinguisher are located behind

the seats to optimize weight distribution. Theflexible fuel tank is placed in a composite housing and

equipped with a refuelling system complying with the

FIA standards. The DS3 R3 can carry two spare

wheels:one under the rollcage and the other in the

original cradle. Under the chassis the mechanical

components are protectedby an aluminium sump

guard, a tunnel housing and a rear skid plate. The car

is delivered with wheel arches in precut polythene.

The gravel kit includes thermally moulded

underbody protection.

From the exterior the DS3 R3 differs from the series

production model by two details: the air intake onthe roof and the rear-view mirrors whosedesign is made to optimize aerodynamic efficiency.

INNOVATIVESUSPENSION

The efficiency and the multi-purpose aspect

of the DS3 R3 owe much to the quality of its

running gear. At the front the sub-frame

is reinforced and modified to accept a specific

tubular wishbone. The original silent blocs have

been replaced by series production joints. The

torsion bar has been heavily modified to

increase the size of the joint and the transmission

groove.

The dampers developed in collaboration with BOS

are mounted in front of the stub axles , and this

provides maximum travel and considerable

guidance length. These tritube dampers consist

of an aluminium McPherson strut lubricated by

an oil bath, an intermediary chrome tube and the

damper in aluminium. They can be adjusted in

three ways (high compression, low speed and

rebound). The hydraulic stop is also adjustable.

These dampers have a patented rapid rebound

system.When going over a jump or in a deep rut

the wheel is literally glued to the road to use the

whole travel during the compression phase. Thepower-assisted hydraulic st eeringuses a series

production rack and pinion systemchosen for the

diameter of its bar and its ratios. The pump is driven

by the accessories belt.

At the rear the H-shaped deformable axle has

been beefed up and modified so that the anti-

roll bar can be easily removed. The detachable

rear hub carriers allow the camber and toe-in to

be adjusted. The spring/damper units have the

same technology as at the front. All the springs in

the range have an identical load under pressure, so

replacing them does not require readjustment of

the ride height clearance.

To adapt the handling to all kinds of driving

styles the camber, the toe-in (front/rear) the width

of the track and the chassis (front) can all be adjusted.

The braking systemhas a double master cylinder.

The balance between the front and rear is achieved

by adjusting the pedal box with a reminder of the

figures on the dashboard. At the front the discs are

clipped by 4-piston Alcon calipers identical to the

asphalt discs (330x30 mm) and gravel (330x30

mm). At the rear the double-piston calipers clip

300x8 mm discs.

The one-piece rims (17 inches for asphalt and

15 inches for gravel) developed for the DS3 R3

are down to the minimum weight imposed by the

regulations.

UN MOTEUR 1.6 THP

AU COUPLE PHNOMNAL !

Pour la premire fois de son histoire, CitronRacing propose un moteur turbo sur un produitcomptition-client. Son dveloppement a t facilitpar lexprience acquise par la marque en WRCdepuis plus de 10 ans. Le moteur 1.6 THP (turbohaute pression) est troitement driv du bloc de srieEP6 CDT. Dot dune bride de turbo rglementaire de

29 mm

, il dlivre une puissance de 210 ch. etun couple de 350 N.m (carburant commercial 98SP). Le moteur de DS3 R3 est livr mont, rodet test sur banc.

Conformment la rglementation, de nombreusespices sont issues ou drives de la srie :vilebrequin, culasse, soupapes, turbo, botier papillon,injecteurs, pompes dinjection, collecteurs dadmissionet dchappement Le filtre air , les arbres cames, les pistons, les bielles et le volant moteur sonten revanche spcifiques la comptition.

Sous le capot, le positionnement des diffrentsorganes a t conu pour optimiser lerendement thermique et faciliter lassistance encourse. Aliment en air frais par une cope placederrire la calandre, lchangeur est situ au dessusdu radiateur. Trs accessible, le turbo peut trefacilement dpos. Son positionnement permet

de faire passer la ligne dchappement

au dessusde la bote de vitesses, et non plus sous le moteur.Le carter infrieur a ainsi t redessin pour abaisserle niveau dhuile et ajouter un cloisonnement vitantles djaugeages. Le circuit deau a t simplifi ensupprimant le calorstat pilot. Certaines durites et levase dexpansion sont mcano-souds.

Le calculateur moteur de DS3 R3 intgre un systmedacquisition de donnes de 8 Mo disposant dedeux modes : spciales et liaisons. Une extension demmoire de 64 Mo avec logiciel dexploitation Wintaxest propose en option.

For the first time in its history Citron offersa turbo engine on a client-competition car.Its development was made all the easier by

the experience acquired in the WRC over

ten years. The 1.6 THP (high pressure turbo)

engine is closely derived from the EP6 CDT series

production version. It has an obligatory 29 mm air

restrictor , puts out 210 bhpand delivers 35MN torque (98 SP commercial fuel). The DS3

R3 engine is delivered assembled, run in

and tested on the test bed.

In keeping with the regulations, numerous parts

are from, or derived from, series production:

crankshaft, cylinder head, valves, turbo, throttle

slides, injectors, injection pumps, inlet and

exhaust manifolds. The air filter , the camshafts,

pistons and connecting rods and the flywheel are

specifi cally desi gned for competiti on.

Under the bonnet the positioning of the different

components has been designed to optimize

the heat efficiency and make race maintenance

easier. Cool air is fed to the exchanger located above

the radiator through an air intake behind the grill. The

turbois easily accessible and can be removed

without problems. Its position enables the exhaust

to be routed over the gearbox and not under theengine. The sump has been designed to lower the level

of oil, and includes compartmentalization to prevent

oil surge. The water circuit has been simplified by

getting rid of the thermostat. Certain lines and the

expansion tank are welded.

The DS3 R3 engine computer has a data acquisition

systemof 8 Mo with two modes: stages and liaisons. A

64 Mo memory programme extension with the Wintax

programme that runs it is available as an option.

UNE GRANDE PREMIRE AVEC

LA COMMANDE DE BOTE PILOTE

Une des innovations majeures de DS3 R3 se

situe au niveau de la bote de vitesses. Pourla premire fois, un produit comptition-clientrallye est quip dune commande pilote, quipermet de rduire de moiti le temps de passagedes rapports et daugmenter la fiabilit, puisquela gestion lectronique nautorise un changementde rapport que si les paramtres du moteur lepermettent. L encore, lexpertise de Citron Racingen WRC a permis lexploitation de cette technologiede pointe.

La bote de vitesses six rapports crabotsa t spcifiquement conue pour DS3 R3.

Le carter recevant lembrayage bi-disque est enfonderie daluminium, tandis que la cassette abritantla pignonnerie est taille dans la masse. Situ danslaxe de la voiture, le dif frentiel autobloquant type ZFpermet dutiliser des barreaux de transmissionidentiques droite et gauche. Leur longueurautorise en outre de grands dbattements.

La commande pilote lectro-hydraulique

est conue partir dorganes de srie

(lectrovannes, actionneurs, groupe de pression).Le bloc hydraulique commande galementlembrayage, actionn automatiquement chaque changement de rapport en raison ducouple moteur. La bote de vitesses est refroidie parun changeur eau/huile.

Dans lhabitacle, la palette de changement derapport est situe proximit immdiatedu volant. Elle reprend lergonomie de C4WRC: le pilote donne une impulsion vers larrirepour monter les rapports et une impulsion vers

lavant pour les descendre. L encore, lutilisation decapteurs de srie permet dassocier matrise descots et longvit. La fiabilit de ce systme apermis dviter le montage dune commandetraditionnelle de secours. Surleve, la pdaledembrayage subsiste, mais elle nest utilise quepour les dparts.

A FIRST WITH

SEMI-AUTOMATIC GEAR CHANGE

O

ne of the major innovations of the DS3 R3 is Its

gearbox. For the first time a competitionclient rally car is fitted with a semi-automatic

shift, which cuts gear changing time by half and

increases reliability as the electronic management

system only allows a gear change when the engine

parameters okay it. Here again, Citron Racings

expertise in the WRC has allowed the use of this

cutting edge technology.

The six-speed dog gearbox has been specially

designed for the DS3 R3.The casing housing the

twin disc clutch is in forged aluminium while the

gear cluster housing is made from solid aluminium.

The ZF self-locking differential is located in theaxis of the car, so identical transmission bars can

be used on both right and left-hand sides. Their

length allows long travel.

The electro-hydraulic semi-automatic drive is

designed from series production components(solenoid valve, actuators, pressure pack etc). The

hydraulic block also controls the clutch, which is

triggered automatically at each gear change

by the engine torque. The gearbox is cooled by a

water/oil exchanger.

In the cockpit, the gear change paddle is

located beside the steering wheel. It uses the

ergonomics of the C4 WRC. The driver flicks it

back to change up and pushes it forward to change

down. There too, the use of series product ion sensors

helps master costs and increase longevity. The

reliability of this system has done away withthe need to have a traditional back-up gear

change system.The clutch pedal is still there

but for starts only.

MASTERING RUNNING COSTS

OUR PRIORITY

C

itron Racing validated the reliability of the DS3

R3 on all types of terrain for all kinds of driving

styles by covering over 10 000 kilometers

in development testing, plus a 7-rally

programmeat the end of the 2010 season.

This reliability is accompanied by easy

maintenance, which was one of the design groups

priorities at the conception stage. For example, the

sump guard and wheels can be removed with the

same wrench.

The mechanics can change the alternator through

the wheel arch, and replace the gearbox without

taking off the engine sub frame. The DS3 R3 issupplied with a tool kitfor assembly and running,

a precharge measure for the differential, wrench for

purging the brakes etc.

Particular attention has been paid to the on-board

electronics with a power box managing the

electric power of the car. This electronic device

is mounted in the cockpit on the central tunnel; it

replaces the usual fuses and diagnoses all the

organs and sensors.Should it be necessary to track

the reason for a breakdown, messages of error are

shown directly on the digital screen.

This screen on the dashboard has six pages for

the driver and eight for the mechanics. Thanks to very

concise, informative messages the car can be run

at its maximum potentialwithout the systematic

need for a computer.

All the setups are supplied by Citron Racing,

which also offers technical backup to personalize

setups according to the events and driving styles.
