After having displayed their 2009 front wing on the presented R30, the team ran a curvy front wing during all winter testing, before introducing this new spec at free practice in Bahrain. While the base profile retains largely the same shape, the cascade element now features a much deeper spoon to catch more air and push it upwards. The item also has extends above the front wing endplate and in fact has its own small endplate attached on the outer edge of the panel.
Also interesting is the lower end of the front wing endplate which sort of forms an extension to the wing's elements. Renault is obviously aware of where they lost last year's development race, and are now pushing heavily on front wing development.
