After analyzing the GP at Silverstone in the previous post ( click here to read ) we go into the details and try to understand the problems that have faced men in Red this weekend trying to spigare because we have seen on track SF70H more "ugly "these first 10 rounds of the season .
After the British race yesterday what matters most and that worries all the Ferrari fans is really dull performance of Ferrari , never really able to fight on equal terms with the Mercedes W08 England. Neither in qualifying them as we could expect, nor in the race, where the great Italian car has always been able to make little difference on the weapon of the 2017 Anglo German Team in the first nine events of this exciting Formula 1 season.
In the preview at the Grand Prix in Silverstone we were talking about a Ferrari that was believed to cause problems the Silver Arrows on their home track but so was not. Speaking in Austria with one of the Top aerodynamics of the team from Maranello we confided that he thought the Silverstone circuit could adapt better to the characteristics techniques SF70H compared to the circuit Austrian Spielberg where, however, in the areas most driven, the second and the third, the SF70H remained very competitive compared to the W08 Hamilton and Bottas . The fast long corners would have to enhance the features of the excellent technical coach of the 2017 Italian Team . And even if Ferrari was still pretty fast in the fast corners, he again paid what for the past several weeks we continue to emphasize, that is a very important deficiency in aerodynamic efficiency point of view . And the confirmation after this tenth round there comes directly from the great protagonist of this season that Sebastian Vettel:
Mercedes I think has a very efficient car from the aerodynamic point of view. This season in 2017, especially on circuits like Silverstone, it's even more important to have a car with high aerodynamic efficiency because there are a lot of corners where we are no longer limited by the grip of the cars and have less drag (with similar levels of load aero) is so important to help the lap time.
Unfortunately, the 2017 project of the Italian team does not revolve around the very important technical parameter called "aerodynamics" , instead of the cornerstone projects in 2015, 2016 and even 2017 Team Anglo German. The SF70H took to the track to the Silverstone Grand Prix have always had aerodynamic structure more loads than those chosen by Mercedes (we have already said n times by now) while clocking a top speed just less than 2-3 km / h sign that the Italian Power Unit has always pushed so important especially in the crucial parts of qualifications or at least does not denote major shortcomings with respect to the power unit Mercedes. A more downforce trim maintained in part in the Grand Prix at Silverstone although Ferrari has tried to load it even further.
The Ferrari has chosen the more exhaust alignment of the three tested between the free practice 1 and 3 of the Saturday morning: wing spoon at the rear, T Wing single profile and a single monkey seat triplane compared all'assetto far more load tested during the first free (watch the photo above) who saw the adoption of two monkey seat and wing from high load average rear. A trim that as discussed above by Sebastian Vettel penalized enormously the aerodynamic efficiency of both SF70H. For the first time Ferrari has wanted to run with the advancement resistance levels closer to those of Mercedes, just also to minimize the technical concept from said Vettel and above but in doing so lost less on the straights but earned less (or even lost ) in the curve. Check out this interesting video ( thanks @gertigj ):
But what many are asking is why Ferrari has failed to be competitive on a plot in which the first part of the season was perhaps the best, ie in the fast corners. What was said now there has always confirmed Sebastian Vettel in pre Silverstone weekend:
Our car on tracks with many fast corners really okay. I think we can have fun. I can not wait.
In short, a Sebastian Vettel who had the same idea dell'aerodinamico FUnoAnalisiTecnica Ferrari with whom he had spoken over the weekend in Austria. But what did not work on SF70H Silverstone?
Rumors circulating in the Silverstone paddock on Friday, as we wrote in the analysis of qualifications, wanted a Ferrari penalized last technique directive sent by the FIA to Team who has forced the Italian Team to close the "knife" (or mobile deflector) in the initial part of the bottom of SF70H. A component that eye would seem unimportant to the aerodynamic purposes of the car but in fact helped to "seal" the outside of the bottom SF70H that adopt this year high rake angle structures. Without the "sealing" original for which it was designed to work at 100% the bottom, Ferrari has been forced to slightly decrease the angle rake on its SF70H to prevent significant aerodynamic losses. But this has however led to a pressure drop (smaller) to the rear that Ferrari wanted to recover by taking more charge wing. But such aerodynamic brought on track during PL1, as previously written, it did not work .
And the car easier to set up, what was clearly the most balanced even with the aerodynamic efficiency limits, what was the best on the Pirelli 2017, in the space of just two races seems to have lost these great features. Yes, because the first components to be affected by an aerodynamic imbalance given by a rear-end no longer so "perfect", to compensate mechanically (as long as there are unable), it is precisely the tires. The SF70H who took to the track in Austria on Friday and Silverstone were less balanced cars and a back less pinned to the ground to those seen in the early races. As if something had really changed after that new pre Austria Technical Directive (and that relating to the oil in the engine in pre Azerbaijan with a PU that pushes slightly less). The whole team had to work overtime to give Vettel and Raikkonen of competitive cars on the Sabbath. In Austria, the work was good also because of a track that could partially mask certain limits (as well as will be most likely in Hungary) but Silverstone is much more difficult, almost impossible.
In conclusion, at Silverstone I came out a little about the "limits" of the project Ferrari 2017 coupled to some restrictions during the season by the FIA . But if the red part of, has over pits the worst weekend of the season, from the gray one can say that it was the best; so be careful to think that the season is completely finished, with shotguns Mercedes easier from now on. Why have the two Team from Hungary could draw closer.
? What else? It doesn't make it much of a stop and go track.
