McLaren introduce stacked front wing

In an attempt to crawl back up the grid, McLaren are doing everything in their power to find extra downforce. One of these measures is an additional deck on the front wing (upper part of image), similar to Red Bull's, and to a lesser extent Toyota's front wing. The element is proven design since Renault introduced it in 2005 on its championship winning Renault R25 and has found wide adoption this year after the more efficient bridge wing solutions were banned for 2009.
