Among the many updates present on various cars at Melbourne, Red Bull certainly has one of the more interesting as the RB10 features a brand new rear wing endplate, including a new solution to reduce the drag induced by the rear wing.
The previously common solution, as seen on the inset, was to add gills on the high pressure side of the rear wing. These gills allowed some air to bleed off from the high pressure area in between the endplates to end up on the outer sides of the endplates.
