BMW Sauber F1.07 - front wing development 30 June 2007

BMW introduced this revised wing in France following last week's Silverstone test (it will probably be retained for the British Grand Prix, as both venues require similar aero configurations). The new design retains the squared central spoon profile, but has a completely new flap (red arrows), which is now much deeper to provide adequate front downforce for this circuit. The resulting increase in drag is offset by the additional upper profiles (green arrows), now shortened to reduce the drag they create.
