BMW Sauber F1.08 , 2008 season – Bargeboard upwards extension up to sidepod panel

November 23, 2011 1 comment

  BMW Sauber F1.08

        The central zone of a F1 car is considered crucial for a perfect aero-balance forcing teams to exploit bargeboard design to the limit (the bargeboards are the large vertical fences located in front of the sidepod inlets ). Sauber during winter testing ( in Valencia on February) launched a never seen before solution to manage airflow towards the rear of the car more efficiently . The team connected the sidepod panels ( the U shaped plate with the intel logo on it)  with the bargeboards via a vertical and slightly curved aerofoil . The purpose of the new pattern is to manage turbulent flow behind the front wheels more efficiently offering a smoother and cleaner flow of air around the sidepod body towards the indy flaps located in front of the rear wheels and diffuser roof favoring downforce production .

Renault  R28

         Renault was the first team to copy the idea launching its own version from the first 2008 race in Melbourne .

PS= Since 2009 many of the car’s body are elements were wiped out due to revised technical regulations aiming significant downforce production cut .
