FIA likely to change exhaust rules again for 2013

The FIA is likely to clamp down further on the use of exhaust gases for aerodynamic performance for 2013. That's what race director Charlie Whiting said in a preview on the regulations for 2012. The rules for this year are probably not enough to ban the blowing of exhaust gases in the direction of the diffuser.

Whiting: “Our objective is to prevent teams operating a blown diffuser, which under certain circumstances infringes Article 3.15 (moveable aerodynamic device). In combination with additional constraints on engine mapping, as described in technical directive number 36 and incorporated into the SECU code, it will limit designers’ ability to exploit exhaust gases for aerodynamic effect. However teams will not unlearn the knowledge they have gained and it is quite likely this area of regulation may need to be revisited again in 2013.”
