If what little we have seen so far from Williams FW40, we were disappointed not to be more than a simple adaptation of the car for 2016 the new regulation and the Sauber C36 allowed us to dream of a change of trend in the swiss team, what is certain is that what we have witnessed in the presentation of the Renault RS17 invites you to see what it is capable of on the track.
Renault has shown to know very well what is the challenge of the Formula 1 and how to win, but the task of competing with a car circumstances as the last year, along with the enormous task of having to rebuild a team, have done which may seem to have forgotten.
Comparison between the single-seater, 2016 (in mirror to be able to set a better comparison) and the new Renault RS17.
Obviously, it will be the track that judgment, because they are not the cars most innovative or the most beautiful that wins, but the most effective. it is Not expected that Renault is goal in the fight for the podium of the night to the morning, but at least the brand of diamond has done honor to its glorious past and has returned to take risks to try to succeed. Something that, in and of itself, because it deserves recognition.
Media different, the S-Duct comes into play
The first thing that draws attention in the front of the car is not the front wing, or the nose, so do nothing more than follow the usual pattern in function of the interpretation aerodynamic drag of each team (in the first case) and the maximum to make it as short as possible (in the second case).
Are the supports (15) of the front spoiler which offer a way up to now never used, looking for a main feature: improve to the maximum possible movement of the aerodynamic flow in the direction of the bottom center of the car. And it is precisely in such a way where we see the entry of the S-Duct (2), that is nothing more than a device with inlet (bottom) and output (top) that improves the flow thanks to that increased circulation. For the rest, obviously the nose of this year, it is more long for the requirements of the regulation and the main layout of the front spoiler takes the form of an arrow, also courtesy of the new rules.
Maximum control of the bottom stream
Although this is not a novelty, nor much less, the top-down view allows us to delve into the complexity of the front wings, with a few routers flow (1) placed under the flaps side and, on the other hand, we can observe perfectly the function of the endplates (3), try to deflect the aerodynamic flow to surround the front tires, a function that this year is even more important for the increase in the size of the same. Something that, in addition, it causes even more turmoil than in the past.
Came to the area more eye-catching of the car French: the central third. In it, the first thing that catches your attention is the spectacular deflector side (7), not satisfied with adopting a vertically more or less elaborate, but begins very ahead of time with respect to the pontoon and, at half height, back up to finish embracing the said pontoon top. To complement said baffle, the designers of Renault have also added various generators of vortexes (9), even under the rear-view mirror after being born from the same cockpit. Not only called the attention to the shape of the deflector (7), but also its size, which is very considerable, no doubt to keep the aerodynamic flow along the pontoon to regenerate its effect in the direction of the rear area.
But the bargeboard (6), although not called so much attention at first glance -who is black does not help-, what is certain is that is huge and also different to the usual, as it starts with the shape of a square for subsequently adopting a most traditional way and finished by connecting with the end of the floor of the car, in a display of aerodynamic study.
To finish with this area, the pontoon (10) have an entry quite reduced in its lower half, causing a considerable undercut at its base and leaving a considerable space (11) to the aerodynamic flow from the set of bargeboards. In addition, the floor of the car is lifted up to simulate a sea wave (19), by creating a channel inside which are likely to feed the diffuser.
air intake suspended
now in the direction of the back end of the car, we found an air intake of the engine (12) systems and adjacent novel, so its first part is entirely suspended on the headrest of the pilot, thus eliminating any interference at the level of aerodynamic flow that circulates in the direction of the bonnet and the rear spoiler.
In that bonnet we see what we can already confirm as the item is vintage, which returns to the catwalks after a few years in oblivion: the shark fin (16), that ends up connecting with the support curved to the mechanism of the DRS (17) which, by the way, has in its flap (14) with the central area of the round, something already used by several computers in one way or another.
In this spoiler we observe another characteristic element of this regulation: the endplates (13) curved for win width -and downforce – in the top half.
‘Size zero’ to the French
To conclude, we can observe without fear to be disappointed, as Renault has managed to get a neck (5) call bottle of Coca Cola really narrow, though maybe not as much as the popular ‘size zero’ McLaren or the designs most extreme of Adrian Newey to Red Bull. This allows the free space (18) in the soil in the vicinity of the wheel and suspension in the rear is really generous, encouraging, without a doubt -if done right- the effect of the already hipervitaminado diffuser this year.
As a complement the end of all this, we find the so-called ‘slots’ (4) in the floor of the car, you are no more than slits, and drivers of flow that have as a mission to tame the turbulence caused by the huge rear wheels of this season.
we don’t know if the Renault RS17 be the points regularly, or even, if you give a shock to the great this season. But it does seem clear that they have decided to apply the philosophy of “nothing ventured, nothing gained”. And when Renault put in that plan, usually go out well.
