Red Bull RB4 - front wing comparison 06 July 2008
During the test session at Silverstone ahead of this weekend's race, Red Bull evaluated a variety of solutions to improve the RB4's balance. One outcome of this intensive work was a revised front wing, as shown in the lower drawing (previous version above). This sports a different main profile that is flatter at its extremities and features two big vertical fences (1) to better manage the airflow passing underneath. In addition to this, the wing profile is wider than its previous incarnation. The endplates now sport narrower horizontal knife-edge profiles with arched extremities on their external lower edge (2 - right arrow), coupled with smaller horizontal winglets in the middle of the endplate (2 - left arrow).
