Toyota TF105 - new turning vanes
A change for Barcelona right in front of the sidepods. Gone is the single horizontal fin featured since Melbourne. In its place is a double element, with the outer part inclined downwards, and the inner one sporting a deeply-curved upward profile. These elements are part of a continuous development of the TF105, providing more efficiency (and hence downforce) from the diffuser and the bottom of the car in general.
