Red Bull RB11 - revised turning vanes

Both Red Bull cars raced in Suzuka with these new turning vanes (main drawing), which were used only by Kvyat at the last round in Singapore - where Ricciardo drove with the previous version (inset).

As you can see, the new version has a more twisted vertical shape (upper right arrow), while the floor section is angled upwards more steeply at the rear. Note also the different position and shape of the horizontal connection between the two turning vanes (centre arrow). Kvyat carried out a back-to-back test of the two different floors on Friday. The changes are designed to improve airflow under the car and hence boost downforce.
