Wing development on R26

Just like McLaren and Midland, Renault developed a low drag wing which only consisted of a single horizontal plane. The gap between the two elements of a regular wing became obsolete as that is designed to prevent flow seperation on wings with high angles of attack. Obviously, the Monza spec wings are not of such kind and therefore make such a gap obsolete, hence also decreasing drag. In addition to that, Renault developed their front wing (lower part of the image) for a low downforce circuit by removing the upper element and decreasing the size of the second plane (pained in light blue).
