Ferrari F2008 - vertical slits in rear diffuser 04 August 2008
A modification on the F2008's aero package in Hungary was this vertical slit in each side wall of the diffuser's central section. The increased pressure generated by airflow passing through the slits helps improve the extraction of airflow in that central section of the diffuser. This in turn helps to slightly increase the downforce generated underneath the car in this area, resulting in better traction - something that was lacking at the previous race in Germany. This change will almost certainly be retained for the remainder of the season, after it proved effective in improving the overall balance of the F2008.
