Ferrari F2007 - winglets and barge-board fins 30 September 2007
At the last round in Belgium we featured the Ferrari T-car's sidepod winglet slits. A revised solution was adopted on all three cars in Japan. The dimensions of the winglet shields have been revised and the shields are now elongated at the front. This helps to reduce turbulence close to the radiator inlets and to clean up the airflow directed towards the rear of the car. This change has been coupled with another subtle one to the barge boards, which have gained an almost triangular fin with an upward-sloping outer lip. Its function is to reduce vortices in this area and improve airflow around the lower section of the sidepods.
