One of the aims of last year's aerodynamic regulation changes was to reduce the interest in aerodynamic developing by limiting the possible development areas, including the front wing. The problem with F1 designers and their teams is that they live for every single tenth, and hence rather then stepping back, a regulation change empowers them to look for other solutions.
Red Bull's RB6 front wing for instance is a development of the RB5 front wing. While Newey traditionally designed cars with simple front wing endplates, they team have taken it so far that the endplates now feature curves and double venting holes.
The wing itself now features 2 slot gaps, the lower one certainly inspired by McLaren's front wing of 2008. The stacked element still consist of 2 combined small wings, providing a better solution for this car than the curvaceous designs that Renault or McLaren have come up with.
One wonders how a front wing can become even more exotic...
