In addition, the official participation of the race in the WRC Citroën, which has won five titles in the FIA Constructors 'World Championship', Citroën Racing has always offered products are designed for customers. Team Champion now has contributed to the rich tradition of Citroen DS3 R3, the model to make its race debut in 2010 at the end. versatile, powerful yet affordable, the Citroën DS3 R3 is becoming the new leader in its class.
Based on the FIA's new Group R3T regulations, Citroen DS3 R3 provides the structure and appearance than the production model, where the production of reinforced steel frame, welded, multi-point roll cage, enhancing the strength of the platform and the safety of the pair of drivers.
Under the hood is a four-cylinder 1.6-liter THP (Turbo High Pressure) engine, which was developed for the production of PSA engines. Special Racing Parts (air box, camshaft, pistons, connecting rods, exhaust and turbo, electronic, etc.) has been used to improve the car's power to 210bhp. In addition to the total power, particular attention was given to increasing the engine torque to improve the grip, one of the most important factors for effective driving performance. With 350nm, the Citroën DS3 R3 engine offers unmatched flexibility on the road.
Citroën DS3 R3 has benefited from the wide experience of Citroën Racing through its participation in the World Rally Championship. As with the C4 WRC, the gearbox offers a six-speed semi-automatic sequential control, which allows gear changes to two times faster than a manual transmission, while improving the reliability of the propulsion system vehicle.
Built with the output from the components and race specific parts Citroën DS3 R3 is available at an affordable price and will be marketed by Citroën Racing in the game and ready for the race versions.
CHASSIS: CITROËN RACING experts when it comes to security
Citroen Racing has put his extensive experience in the field of passive safety and chassis rigidity is the Citroën DS3 R3. Standards monocoque frame is lighter, because it is not used to support the production model. It 're-welded and features a multi-point roll bar in more than 45 meters of steel pipes. Roll the industrial design is pre-assembled outside the car, which means a better quality of welding. Various details of the case, such as slings, crosses, and the door to cross the tracks, to improve the safety of the driver pairing. Self-supporting frame is equipped with all brackets and hardware needed to assemble a car, which reduces construction time and costs.
To improve weight distribution, battery and a sprinkler is positioned behind the seats. A steel skid plate protects the bottom of the engine also helps lower the center of gravity of the car. The flexible, FIA approved fuel tank is kept in its original position.
ENGINE: pump hose 1.6-liter Turbo with incredible moment
For the first time, the Citroën Racing has developed a product to the customer switch is equipped with a turbocharged engine. The experience of fire in the WRC in almost ten years has been utilized in its design. The 1.6 liter THP (Turbo High Pressure) is very closely related to the production model used in the PSA. Equipped with a regulation under 29mm turbo flange, it develops 210 bhp of power and 350Nm of torque from (with the fuel commercially available). The second value improves traction and provides versatility to all engine speeds.
According to regulations, many parts have been taken or derived from the production model. For example, intake manifolds and exhaust, turbo, injectors and injection pumps are identical to those used in the production models. The air filter, camshaft, pistons, connecting rods and steering wheel, however, are pieces of a specific race. To prevent the oil comes in the long corners and increase ground clearance, oil pan has been modified and equipped with a composite score. The exhaust system and turbocharger is also specific, catalytic converter is similar to that used in the C4 WRC. Citroën DS3 R3 engine ECU also includes a data acquisition system that is able to see a large number of parameters.
TRANSMISSION: with a first semi-CONTROL
An important innovation of Citroën DS3 R3 for transmission. For the first time, a product for the client's career has been equipped with a gearbox semi-automatic, which reduces the time spent changing the speed and increases reliability. The electronic management system allows speed changes only when the engine parameters permitting. Again, the experience of Citroen WRC Race has allowed this technology must adapt to Citroën DS3 R3.
Under the hood, the specific elements of a semi-automatic control (valves, actuators and pressure units) are all taken from the production model and adapted to a six-speed gearbox. Twin-disc clutch housing is a die-cast aluminum gear housing, but is cut into wedges.
Development: over 10,000 miles of testing
After twelve months in the design office of Citroën Racing, Citroen DS3 R3 made its first appearance in late August 2009. To check the robustness of the different components, the initial test was conducted on test tracks "of coarse gravel" road surfaces typically seen in the Mediterranean Rally. Evidence of continuous development in the asphalt, the ideal surface to test the performance, and flowing gravel roads. A total of R3 DS3 Citroën covered over 10,000 miles on developmental tests, divided evenly between the different types of road surfaces.
