Are Red Bull attempting to blow the rear wing through the rear wing support?
I know they've had rounded upper edges for their engine covers, but the roundness of the rear wing support, and the way the base bends to meet the back of the engine cover, as well as the fact that the support now attaches to the DRS control mechanism, makes me believe that their is airflow going through there. I also note that there are two sort of curves on the engine cover, one that goes down and flows into line with the exhaust pipe, and then there's the upper part that foes down to the rear wing support.
