GP Week : Issue 161
Silverstone as a track means returning to a real circuit with very fast corners. This track, of huge tradition, is usually a sort of test bench for the cars. Even if it can’t quite be compared to Barcelona, in terms of how important the aerodynamic side of things is, it is important to ensure whether the cars have a good balance, and top speed performance _ as well as good tyre wear/use characteristics. Here tyre wear is high, and for this reason Pirelli decided to bring the new hard compound to Silverstone. Not all the changes that were supposed to be introduced here, effectively were, but it was interesting to note that some of the top teams brought here some refinements to their packages, that we can consider much more sort of optimizations that can be important on such kind of circuit, than proper bigger evolutions of their package. Ferrari was supposed to bring a new aero package e in terms of new front and rear wing. Instead, mostly due to the poor weather conditions during the practice session and thus that it was not possible to carry out a proper evaluation, it was decided not to carry the new wing for the remainder of the weekend. The new wing, together with further elements, will be brought to Hockenheim in two weeks time. As already mentioned, some teams brought interesting refinements; one of those was Red Bull who, after bringing to Valencia a deeply revised rear end, here just improved the efficiency of the solution introduced one race ago. The area around the exhaust pipes has been in fact slightly modified, by means of a sinuous profile cover around them, that has the function to divert the exhaust flow towards the lower section of the bodywork, so to improve the airflow passing through the slit placed in the lower section of the sidepods, that has remained unchanged from last race. Another team that introduced here an interesting change was McLaren, sporting a revised front wing. The new assembly differs in the second flap section. While the previous version sported a single element, now the flap is divided into two parts. The outermost is fixed, not adjustable, while the inner section can be adjusted. The mechanism that adjusts the flap angle is also changed, being thinner and smaller compared to the previous one, so providing less drag. The new wing was used in qualifying and in the race by both McLaren drivers. It is expected that this element will remain on the car for the next races, as it proved efficient in terms of reducing, thanks to the fixed section of the flap, turbulence in the area of the front wing, improving the aero efficiency of this area of the car and front end stability as a consequence.
