Frontal airflow management on Toyota TF109

By on

Although the lacklustre showing in qualifying suggests otherwise, Toyota keep on working on their TF109. One little detail we spotted is the addition of a small winglet on their sidepod panel. As it concerns a fairly flat aerofoil, it looks like it's aimed at reducing turbulence from behind the front wheels, attempting to improve the flow towards the rear end of the car.

Also marked in the image are the turning vanes that Toyota have been using. Fitted in between the front wheels and just under the nose, it is also aimed at directing airflow better. This element is particularly interesting because the FIA aimed at banned this kind of elements with the new regulations, but with the right approach something is still possible there. It is this area that Renault is using to make its venturi under the nose cone of the Renault R29.
