Citroen C4 WRC
From concept car to the slopes
result of collaboration between specialists in design and competition, the C4 Citroën Sport concept car was a project that was not put to any statutory limitation, a true exercise in style, a challenge to articulate a vision futuristic successor to the Xsara WRC, car 3 times winner of the World Builders, between 2003 and 2005. After passing through the expert hands of Citroën Sport's engineers at Versailles Satory, the C4 Citroën Sport concept car became the C4 WRC.
Adjustment rules
The working group on this issue stock builds a first version, far from the original concept car. For example, the glass ceiling no longer, as it is banned in rally racing. The front and rear wings, bumpers and spoiler were modified in order to meet the performance criteria and regulations. Various body components are studied in the wind tunnel, in a first phase at ¼, to save time and money, before being finally approved actual size. 
outline of the development program
development program is validating and mechanical parts designed by Studies Office. In a first step, we study the reliability and in the second performance. To do this, it has taken several workshops in both asphalt and gravel. Then the technical team of Citroën Sport C4 performance compares with the Xsara WRC, which is the great reference. Development phase, the Citroën C4 WRC features a great potential and efficiencies that can be verified only during the competition.
expectations and objectives
In Citroën Sport, mechanics, engineers, pilots, and managers looking forward to the race result, with a C4 WRC has been designed to be as easy to drive and as reliable as the Xsara WRC, but with greater performance and efficiency. A car built and developed to try to win the Constructors' World Championships and Pilot, from 2007. 
Main technical characteristics of the Citroën C4 WRC 
Like his illustrious brother, the Xsara WRC, the C4 WRC is a vehicle that has 4 wheel drive and a 2-liter turbo engine mated to a transverse gearbox 6-speed. The specificity of the C4 WRC is longer than the Xsara, to exceed 4'20 m. This allows, by regulation, benefit from a greater width, which goes from 1,770 to 1,800 mm. This change provides, theoretically, increased cornering stability. As it imposes new regulations have reduced the electronic driving aids to levels identical to that of the Xsara WRC 2006. Regarding the budget cuts imposed by the regulations, the subsets of the C4 WRC, such as engines, gearboxes, differentials front, center and rear shock absorbers, etc.. should be more reliable and designed to last longer.

| The scx c4 is one of those cars that must be present in our collection. | The car is really well done with a near-perfect measures.
But speaking outside good, very well achieved in this case we have the bull of altaya network with the same paragraph Dimensions and mechanical than
scx motorization the classic double the rx81 b axis in this occasion with bronze gears and teeth 9 of 27 plastic crowns.
always remember that these models much appreciated and a good running prior to mesh more smoothly the whole crown, pinion, and engine.
Let us play with the model to the track to see its behavior. Remove the magnet and roll, from early moves we like this car gives us a sense of focus behavior of the same make, sure are not careful, a great time curves, the grip of the tires is right, lets you control the car and also move the rear if necessary.
stopped at boxes for a review and some changes that allow us to get all the juice this c4, to disarm the car was not surprised to find that the rear axle was slightly bent so showed no problems even in the first test. assemble wheels ninco brand pro 16 "that really are very good, we changed the ratio to 24 in the crown 27 on the front and rear axles pro calibrated and shredded tires.
The car changed radically and another, the change of relationship makes the things out of the corners and increased grip from the wheels fall time ago, management is somewhat more complicated but is carried away, while the car is rather narrow and somewhat high, really do not notice Carried away by the sections with ease and preparation do not really take long. It really is a car highly recommended to have and enjoy and not Ableman of track lighting is excellent.
ovbiamente not live up to the ninco by ovbios and "wide" reasons, but this model has been rallying scx perfect. here's another good note c4 but ninco by our friend read
