Ferrari F2008 - revised front winglets 23 August 2008
Ferrari introduced a horizontal slit in their front winglets at last year's Belgian Grand Prix and then revised the design slightly in Japan. For the first time since then, the team have abandoned the slit in Valencia in order to increase the winglet's vertical surface area and thus maximise its ability to divert airflow. The function of the horizontal slit was to cut down on turbulence close to the sidepod inlets. The downside was a loss in quality and quantity of airflow directed towards the rear of the car. On a medium-fast circuit like Valencia, the revised vertical shields are more efficient in this respect, helping to extract the hot air from the top of the sidepod gills.
