The diffusers are only a part of it, and not necessarily the major part. The aerodynamicists reckon that for a given amount of downforce, under-body structures produce a quarter of the turbulence that wings produce. They'd do better to cut downforce by restricting wings. However it's done, if we want to see a lot more overtaking then they need to be cutting downforce by at least a half, probably more. Minor tweaks to diffusers or wings aren't going to do that.Quote:
