TECHNICAL the difference is less dramatic in the sector ’s time sheet, but visible. The same situation applies for Vettel and Ricciardo, with their performance alternating according to each sector, in favor of the first or the latter, but showing clearly in the speed trap chart how the downforce load chosen by Vettel was hugely higher than the one chosen by Ricciardo who flew high in the fastest of the three track sectors. The same applied to Mercedes, where Rosberg prevails in terms of speed trap performance, and even sector times, showing in this way an exception if compared to the other cars. We can underline that the main difference in terms of performance of the two W05 hybrids was mainly due to the approach chosen by the respective drivers in terms of taking risks. Analyzing the driving style of Rosberg and Hamilton, we are able to see that Rosberg decided on a total attack approach, while Hamilton already looks focused on title calculations, trying to minimize risks when unjustified. Furthermore, as we wrote in the analysis from Japan, Mercedes hasn’t stopped introducing interesting developments on their cars. In particular, as we predicted, a completely new diffuser was brought here, different in its central section and featuring a different array of vertical fins to divide and divert the airflow passing in its central channel. It is a change of such extent that we can consider it unusual at this stage of the season, but that is justified by the dominant position of the team, that is carrying out huge aero testing in relation to experimentation solutions for next year ’s car. Indeed, for us technical commentators, it is astonishing that Mercedes is the team that is introducing the highest rate of developments in this last stint of the season. Other teams added small degrees of new parts here, and one of these was McLaren. Of course for the Woking-based team, the development ratio is constrained by the fact that next year their power unit will be provided by Honda. So the team has focussed at this stage on the car ’s front end. This area of the car in fact can still provide on the current MP4/29 a good test bench for the aero package. An experimental front wing was just tested in practice, featuring a sinuous central section whose function would be to better manage the airflow in this area to reduce turbulence and divert airflow in the splitter section of the bottom of the car. Ferrari on the other carried out some aero experiments mainly focused on the rear wing, by placing two pitot tubes on the wing’s endplates to collect data in terms of airflow speed close to the boundary layer of these elements. As you can easily understand, the current ranking situation allows all the top teams to now mainly focus on 2015 already – so the remaining races, will be particularly interesting race weekends for us tech commentators, providing some sort of preview to the most crucial areas of next year ’s cars. F1 never stops, always providing something interesting to be discover, evaluate and explained. After all this is what makes our job so special. For now, dasvidanjia. See you in Austin.
