Renault R28 - barge board detail 16 March 2008
It is interesting to note how quickly BMW Sauber's barge board solution for the F1.08 was adopted by Renault on their R28 (circled and red arrow). This area is crucial, as it manages the flow of cooling air to the car's radiators and can also be used to divert air towards the rear wing to create an almost continuous horizontal flow. Depending on the aerofoil configuration, this can generate significant amounts of downforce, without increasing drag.
