We also wrote that Ferrari was expected t o bring to Yeongam a new wing that could be considered as a preview of the one that will be adopted by next year’s car. This happened as expected, with Alonso and Massa making back to back tests over the weekend, with the Spaniard on duty to use the new item. In contrast to the Red Bull advertising motto, we can say that the new wing didn’t give Ferrari wings. ... the poor result in qualifying for both cars, testimony the fact that the new device was not capable of providing an extra aero performance. Notably, the car was not fast in the very long straight where DRS was activated. It is important to understand that the new Red Bull-inspired front wing (below right) , featuring a long slit in the main profile, and just a single main flap, compared to the two of the version used in Japan, (top) didn’t fit perfectly with the current aero layout of the F150* Italia. The new version sports a wider central wing section compared to the previous one, hence reducing the outer profile, that now has lost the knife-edged junction and additional vertical winglet. This wing, in reality, according to some engineers we were able to speak with during the Korean weekend, wasn’t aimed to give the current car a big boost in terms of performance. Instead it is considered important to understand how the font end of the rival RB7 works and how it influences all the aero balance of the car. The set-up of the RB7 is notably deeply raked and this worked perfectly in terms of aero balance and rear diffuser feeding, with a high- pressure air flow. The 150° Italia, sported for most o f the season a more ‘neutral’ set up, except while using the new rear suspension that made its debut at Silverstone. This configuration, retained here, was in reality not able to give the car an adequate gain in terms of speed on the straight and on the fast corners – while it was pretty good in terms of handling in rapid direction changes. In India in two weeks time another step in terms of development is expected for the 2012 car, but Ferrari will surely be not alone in this respect, with McLaren and Red Bull notably, pushing in that direction as well, now that also the constructors championship has its winner.
