Toyota TF108 - rear wing development
Toyota have brought to Silverstone a modified slitted rear wing (red arrows). Though not entirely new, the wing features a completely revised flap, the depth of which has been reduced at its centre to minimise any airflow blockage. The lower portion of the airflow now passes through the slit, creating a sort of venturi effect that improves the extraction of air passing under the profile. The reduced depth of the flap enhances this effect, providing better stability thanks to the more stable downforce load.
