a week Ago at this hour, the FIA began to let the stream of information coming from the World Council of the Motor held in Mexico. One of the main points of attention is found in the technical regulations of the World Rally Cars from the season 2017. What is certain is that it was worth the wait, at least in the mechanical part, because the new WRC will be provided with flange of 36 mm and approximately 380 HP of power, the more of a rally car in the World since the time of the Group B.
In 2016 will celebrate 30 years of the abolition of precisely those monsters and it seems that the FIA has agreed with the manufacturers to make a particular tribute on the basis of the current models. Is more, if we take the concept of the Audi Quattro S1 and we take the list of expected changes, we realize that the Federation is trying to do a Group B modern. Wings large, aerodynamics, more elaborate, more cars, wide wheel arches, side skirts… Now look at the picture of the model of the four rings that heads the article and tell me what item that I have listed does not appear.
what are The differences? First we can say that any invention or rally car, that come now will not be able to match the myth. , because the Group B have a part of it, mysticism, like all those artists or geniuses that were young. The sound of it, the public freaked, the rudimentary models and rallies that put to the test both teams as pilots. On that basis, the new World Rally Cars already start at a disadvantage, before you even move from paper to reality.
If we look at the technical basic data, we are talking about 380 HP to 1205 kg in the case of the WRC’17 and 550-600 HP to 1090 kg in the Gr.B. In theory, only looking at the numbers, the 2.0 kg/CV are overwhelming, however, the current WRC (the engine 1.6 Turbo, flange-33 mm and 320 HP) were already faster the cars of three decades ago with almost half the power.
And is that the development of tyres, brakes, transmission, and especially suspension, make that the World Rally Cars are the cars more technologically advanced and rapid in the history of the discipline. Something that especially it should be noted in the special very twisty and narrow, in which the ancient and dilapidated Group B were even, on occasion, to engage the reverse gear to maneuver and make the turns more are closed.
But… Is that the only point at which the new WRC will be superior to these long-cherished models? Negative. The center differential, driven electronically (front and rear remain blocked and will continue to be mechanical, while the change will remain sequential 6-speed), systems such as the ALS or the output (electronics) make the pair of these new World Rally Cars will go to an impressive 500 Nm, 100 more than what they get today, and at levels similar to those of the Audi S1 Quattro, Peugeot 205 T16, Ford RS200 or Lancia S4.
The back of the dif. central will the cars are easier to get to the point, depending on least of the test (cutting obviously part of the costs of doing set-ups). But it can also make cars go more under control and miss a part of that spectacular to see the WRC completely adrift, something that was taken up again in 2011 with the disappearance precisely of that element. It remains to be seen if cars with better Power to Weight ratio this will change and we will see cars more spectacular also in motion. Since then, will undoubtedly be cars rally more rapid in the history of the WRC.
Now, as much as it hurts, it compares the sketch of that kind of a Ford Fiesta RS WRC’17 devised by the FIA with the Audi in the beginning…
