According to the Swiss publication Motorsport Aktuell,Williams and Toyota believe their controversial diffuser designs for 2009 are legal, and it is likely the FIA will not intervene.

It was reported last week that rival teams expressed concerns about the legitimacy of the two teams' separate designs, after "clever aerodynamic shaping" was used to sidestep the regulation about the maximum height of 175mm.

Motorsport Aktuell, however, claims that the designs - while using a loophole for extra bodywork not intended for diffusers - conform to the letter of the technical rules.

Separate technical analysis published on F1's official website describe Williams' design as "highly innovative", and Toyota's "very interesting", as both use clever shaping of the rear crash structure to effectively increase the height of the diffuser.

It is believed that the teams in question, who are both powered by Toyota's 2.4 litre V8 engines, separately got clearance from the FIA about their interpretations of the 2009 rules.

The FIA has not confirmed publicly that the designs are legal, however, and a rival team can only lodge an official protest once the cars are presented for scrutineering in Australia late next month.
