Toyota TF106B - turning vanes and winglets
In Hungary the winglets in front of the sidepods have been changed for the third time this season. The vertical endplates are completely different to the previous version introduced at Silverstone, sporting a rounded front edge (blue arrow) to reduce the drag caused by vortices generated between endplate and sidepod edge. A further change is the wider vertical turning vanes (red arrow) connected to the horizontal fins in front of the sidepods. The vertical shields are higher than before, increasing the airflow diverted into the sidepods air inlets, aiding cooling in hot weather conditions.
