Citro?n DS3 R3 ready for client fight
Citro?n has only introduced the brand new customer convene automobile for a FIA’s Group R3T category formed upon a DS3. The DS3 R3 will be accessible as possibly the turn-key racehorse or the do-it-yourself pack. Either approach, energy comes from a 210-horsepower high-pressure turbocharged 1.6-liter inline-four pushing by a six-speed semi-automatic consecutive gearbox. Shifts have been rubbed around co essential element paddles mounted upon a back of a steering circle.
The cessation has been grown to have it simply variable to dissimilar racing surfaces trimming from sand to tarmac. Tubular wishbones have been trustworthy to the revised front subframe while a back hubs have been removable to concede for eccentric toe as well as cove adjustments.

[Source: Citro?n]Full PR text:CITRO?N DS3 R3: A NEW CUSTOMARY
In addition to Citro?n Racing’s central participation in WRC, where it has won 5 FIA World Championship Constructors’ titles, Citro?n Racing has regularly offering products written for clientele. The holdup group has right away furthered this abounding convention with Citro?n DS3 R3, the indication set to have the rallying entrance during the finish of 2010. Versatile, tall opening as well as nonetheless affordably-priced, DS3 R3 is set to turn a brand new personality in the difficulty.
Based upon a FIA’s brand new Group R3T regulations, DS3 R3 features a same constructional pattern as well as appearance as the prolongation indication, with a prolongation steel physique bombard reinforced by the welded, multi-point hurl enclosure, mending a essential element of a framework as well as reserve for the motorist pairing.
Under a carp lies the four-cylinder 1.6-litre THP (high vigor turbo) engine, that has been grown regulating the PSA prolongation engine. Specific racing tools (air box, camshaft, pistons, connecting rods, empty as well as turbo systems, electronic section, etc.) have been deployed to progress a car’s energy to 210bhp. In further to the overall energy, special courtesy has been given to augmenting the engine’s torque to urge traction, a single of a pass factors in delivering efficient pushing opening. With 350Nm, a DS3 R3 engine offers peerless flexibility upon a highway.
DS3 R3 has benefitted from a extensive imagination acquired by Citro?n Racing by the involvement in a World Rally Championship. As with a C4 WRC, a six-speed gearbox facilities semi-automatic sequential carryout, enabling rigging changes to be done twice as fast as with the manual gearbox, whilst additionally mending a trustworthiness of a car’s powertrain.
The cessation system uses a really ultimate technologies as well as has been written for all highway surfaces, from severe gravel to smooth tarmac. A far-reaching accumulation of setup options have been accessible, permitting DS3 R3 to be blending to all pushing styles. Citro?n Racing recommends the use of BFGoodrich tyres.
Built regulating production-derived components as well as specific racing parts, DS3 R3 is accessible at an affordable cost as well as will be marketed by Citro?n Racing in kit as well as ready-to-race versions.
FRAMEWORK: CITRO?N RACING, EXPERTS WHEN IT COMES TO RESERVE
Citro?n Racing has deployed the endless imagination in pacifist reserve as well as framework acerbity upon DS3 R3. The customary monocoque framework is lighter since it does not have the supports used upon the prolongation indication. It has been re-welded as well as propitious with the multi-point hurl enclosure done of over 45 metres of steel tubing. The industrially written roll enclosure is pre-assembled outward a automobile, that equates to a fusing or melting is of the aloft extravagant. Various sum of a framework pattern, such as a strap cross-member as well as a doorway crossbars, assistance to urge safety for a motorist pairing. The monocoque framework is delivered with all the brackets as well as mountings compulsory to arrange a automobile, that reduces a construction time as well as price.
In sequence to urge weight placement, a battery as well as automatic glow extinguisher have been positioned at the back of a seats. A steel skidplate protects a underside of a engine as well as additionally helps to lower a car’s centre of sobriety. The flexible, FIA-homologated fuel tank stays in the strange position.
BELLIGERENT COUPLE SYSTEMS: VARIABLE AS WELL AS HIGH-PERFORMANCE CESSATION
DS3 R3’s potency upon all highway surfaces stems from the quality of the cessation complement, written to have full use of a Group R regulations. At a front, the prolongation sub-frame has been changed so which tubular wishbones can be propitious. The spindle is both lighter as well as stronger than upon a prolongation indication. Developed in conjunction with BOS, a shock absorbers exaggerate multiform innovative facilities:
– The aluminium struts have been lubricated in an oil bath, that improves a coherence as well as lifespan of a cessation.
– The reduce, frontally-offset anchor point helps enlarge the transport as well as a running length of a shock absorber.
In sequence to conform the highway doing to all driving styles, DS3 R3 offers the accumulation of setup options: 3 track startle absorbers (low and high-speed application as well as miscarry, tractable hydraulic bump stop), cove as well as toe (front and back, lane breadth as well as castor (front).
At a rear, a production cross-member has been reinforced as well as altered to have it simpler to fit a anti-roll bar. The removable back circle hubs concede a camber as well as toe settings to be practiced exclusively.
The braking complement facilities the ‘pedal box’ public with dual master cylinders. The discs are hold in place by four-calliper pistons during a front as well as two-calliper pistons during a back. The handbrake is hydraulic.
ENGINE: A 1.6-LITRE HIGH-PRESSURE TURBO WITH INCREDIBLE TORQUE
For a initial time ever, Citro?n Racing has constructed the customer-racing product fitted with the turbocharged engine. The knowledge acquired by a brand in WRC for roughly 10 years has been put to great make use of in the pattern. The 1.6-litre THP (high vigor turbo) engine is really closely related to a production indication used via a PSA Group. Fitted with the regulation-compliant 29mm turbo prong, it develops 210bhp of energy and generates the torque of 350Nm (with commercially accessible fuel). This second worth improves traction as well as delivers glorious flexibility during all engine speeds.
In suitability with a regulations, most parts have been taken or derived from a prolongation indication. For e.g., a intake and empty manifolds, turbocharger, injectors and injection pumps have been identical to those used upon prolongation models. The air filter, camshaft, pistons, joining rods as well as engine flywheel have been, however, specific racing tools. To avoid oil surges during prolonged corners and to enlarge belligerent clearway, a oil sump has been changed as well as fitted with the combination partition. The empty as well as turbocharger complement is additionally specific; a catalytic converter is identical to a a single used upon C4 WRC. DS3 R3’s engine ECU additionally includes the interpretation merger complement that is means to check the vast series of parameters.
GEARBOX: A MAJOR INITIAL WITH SEMI-AUTOMATIC CARRYOUT
One of a categorical innovations upon DS3 R3 concerns the gearbox. For a initial time, the customer-racing product has been propitious with the semi-automatic gearbox, that reduces a time outlaid becoming different gears and increases trustworthiness. The electronic government complement usually authorises rigging changes when a engine parameters concede it. Once again, a imagination grown by Citro?n Racing in WRC enabled this cutting-edge record to be blending to DS3 R3.
Inside the cabin, a combination twine steering wheel-mounted paddles have been only as ergonomic as upon C4 WRC: a driver flicks the paddle retrograde to pierce up a gears as well as flicks it forwards to move down a gears. The clutch pedal is still benefaction, though is usually used to drive off. During successive rigging changes, the clutch is automatically tranquil.
Under the carp, a specific elements of the semi-automatic carryout (solenoid valves, actuators as well as vigor section have all been taken from a prolongation indication as well as blending to a six-speed gearbox. The housing for a twin-disc clutch has been expel in aluminium, while the gearing surrounding has been cut from a retard.
DEVELOPMENT: OVER 10,000KM OF TESTING
After twelve months outlaid in Citro?n Racing’s pattern bureau, DS3 R3 done the initial tour during a finish of August 2009. To check a sturdiness of a assorted components, primary contrast was carried out on ‘rough gravel’ test marks, standard of a highway surfaces seen in Mediterranean rallies. Development contrast one after another upon tarmac, a preferred aspect to exam opening, as well as upon issuing sand roads. In total, DS3 R3 lonesome over 10,000km in growth testing, separate uniformly among a dissimilar sorts of highway surfaces.
Several drivers took partial in a tests. They all had varying levels of knowledge, dissimilar preferences as well as driving styles, that meant which the engineers could accumulate interpretation which will benefit destiny DS3 R3 owners. All of a drivers concluded which a automobile was easy to drive as well as highlighted 3 strengths: a torque of a 1.6-litre engine, a semi-automatic gearbox and a cessation. DS3 R3 offers considerable opening levels as well as looks set to turn a brand new personality in its difficulty in rallying.
