Not for the first time in their short F1 history, Red Bull have caused controversy regarding flexible bodywork around the front wing area. In Abu Dhabi both RB10s were excluded from qualifying after the FIA discovered that the upper flap on the front wing was flexing far too much, induced by an illegal device that is believed to be in the form of a leaf spring.
Back-to-back events never really give teams a chance to bring anything new to the table at the second GP event and Brazil was a classic case of this as the F1 circus headed straight from Texas to Interlagos.
Much of the weekend’s practice sessions was spent analysing components ahead of 2015, using large pitot tube arrays to gather information about critical areas where airflow is passing. Whilst CFD and wind-tunnel testing are pretty reliable it is important to transfer the knowledge gained in the factory to the track, hence why the often-used C-word, correlation, is vital to the performance of an F1 car.

In terms of tech droughts it would be fair to say that the past month has certainly been through one. Thanks to customs regulations in Russia there were little new parts three weeks ago and the teams had to compensate in Japan. Thankfully after a healthy break and more relaxed laws over goods, the US GP was a perfect opportunity to bring developments. Some teams even brought 2015 prototype components for evaluation. The Circuit of The Americas is an ideal proving ground for such parts as the track tests aerodynamic performance to quite an extreme: high speed corners and long straights force teams to cut drag whilst retaining a high level of downforce.
