Rear diffuser controversy

FrankoQ · 03-19-2009, 02:10 PM

We hear a lot of noise regarding the rear diffusers of the Brawn, Toyota and Williams cars.
Quote from Charlie Whiting:
"They used a loophole (in the regulations) that was always there"

Does anyone know what this loophole is?

Mr Google found this:

"The controversy over Toyota, Williams and Brawn GP’s rear diffuser arrangements is dragging on and is unlikely to be settled until the first race on 29 March, Forumula1.net understands. The three teams have innovative designs for their rear diffusers, which rival teams accuse of breaching the maximum height allowed for the structure. But the legality or otherwise of the design will not be confirmed until Melbourne, when the first official protest may be lodged by other teams."

From www.formula1.com:

"McLaren, Ferrari, Renault and BMW Sauber have all made very literal interpretations of the revised 2009 rules regarding the rear diffuser. All of the channels are the same height and length, with no difference in height between the main central section and the side channels. This contrasts with the designs of Toyota and Williams (see subsequent illustrations), which interpret the new regulations slightly differently."

"Toyota's diffuser makes a very interesting interpretation of the revised 2009 rules (and one that has already prompted speculation regarding its legality). By exploiting regulations that allow extra bodywork within a 150mm zone in the centre of the car, the team appear to have cleverly shaped the TF109's rear crash structure (upper red arrow) so that it effectively lengthens and heightens the diffuser's central section, which also features a very low splitter at its base (lower red arrows)."

"Like engine suppliers Toyota's, Williams' interpretation of the revised diffuser regulations is highly innovative. Much of the diffuser's central section is actually lower than the outer sections. However, clever shaping of the rear crash structure immediately below the rear light effectively creates a second central section (red arrow). In combination, the result is a central section that exceeds the 175mm height allowance that applies to the diffuser alone."

If the FIA can't clarify the grey area of diffuser and crash structure...why don't they just "standardise" the rear diffuser/crash structure design (as the FIA already trying to standarize EVERYTHING in Formula 1).....

too much regulation in all the races F1 and rally makes the race so stupid. They should just let everyone race on with their best technology so that we can always see the best.
