BMW Sauber implement tiny louvers in sidepod

BMW Sauber's newly launched F1.09 features an interesting solution to provide cooling in the sidepods. It is already a wide known fact that openings other than the exhaust exit are forbidden on the sidepod shell, but the team of Hinwill managed is exploring the edges of legality. Just above the car's floor, the team added a very small series of louvers to provide an exit for hot radiator air.
