Ferrari F2007 - front wing development 19 October 2007
At Interlagos the challenge is to balance straightline performance with driveability on the twistier sections. The circuit's high altitude means lower air density, hence higher wing angles are needed to obtain adequate downforce levels. Alternatively, air pressure can be raised by better airflow diversion in certain areas of the car, as with Ferrari, who have increased the cross-sectional area of the small winglets placed under the wing's upper profile near the endplates. This change raises the pressure of the airflow passing underneath, slightly increasing downforce, but without having to dramatically alter the wing angle, hence keeping drag as low as possible.
