The diffuser Appeal
Court of Appeal declares disputed diffusers legal

The FIA International Court of Appeal (ICA) has rejected protests against the diffusers used by the Brawn, Toyota and Williams teams, after concluding that their ‘double decker’ designs comply with the 2009 regulations.

BMW Sauber, Ferrari, Red Bull and Renault had all questioned the legality of the diffusers, but following Tuesday’s hearing in Paris, the ICA decided that race stewards in Australia and Malaysia had made the right call in declaring them legal.

Full statement from the FIA:
The FIA International Court of Appeal has decided to deny the appeals submitted against decisions numbered 16 to 24 taken by the Panel of the Stewards on 26 March at the 2009 Grand Prix of Australia and counting towards the 2009 FIA Formula One World Championship.

Based on the arguments heard and evidence before it, the Court has concluded that the Stewards were correct to find that the cars in question comply with the applicable regulations.

Full reasons for this decision will be provided in due course.

Toyota and Brawn welcome FIA diffuser decision

Toyota and Brawn GP have responded with pleasure to news that the FIA’s International Court of Appeal has declared their rear diffusers legal. Along with Williams, the two teams had been racing under appeal after rivals questioned the legality of their ‘double decker’ designs, despite stewards at March’s Australian Grand Prix authorising their use.

In a statement released after the FIA’s announcement on Wednesday, Brawn GP team principal Ross Brawn said: "We are pleased with the decision reached by the International Court of Appeal today. We respect the right of our competitors to query any design or concept used on our cars through the channels available to them.

"The FIA Technical Department, the Stewards at the Australian and Malaysian Grands Prix and now five judges at the International Court of Appeal have confirmed our belief that our cars have always strictly complied with the 2009 Technical Regulations. The decision of the International Court of Appeal brings this matter to its conclusion and we look forward to continuing on the track the challenge of what has been a very exciting start to the 2009 FIA Formula One World Championship."

Toyota commented: “Toyota Motorsport is pleased to hear the FIA International Court of Appeal has upheld the decision of the Australian Grand Prix stewards concerning the rear diffuser on our car. As we have maintained throughout, our team studied the wording of the new 2009 regulations in precise detail to ensure we interpreted them correctly.

“We also made full use of the consultation procedure with the FIA which was a helpful process to ensure our interpretation of the technical regulations was correct. Therefore we had every confidence that the design of our car would be confirmed as legal, firstly by race stewards in Australia and Malaysia and subsequently by the Court of Appeal.”

Toyota’s chairman and team principal Tadashi Yamashina was equally satisfied with the Court’s decision: "I was confident the Court of Appeal would reach this verdict and I am satisfied with it. It is important to stress we studied the technical regulations in precise detail, consulting the FIA in our process, and never doubted our car complied with them. This has been a challenging period for Formula One and I am pleased this issue is now in the past and we can focus on an exciting season on the track."

Brawn GP, who are currently leading the constructors’ standings on 25 points, and second placed Toyota (16.5), will be back in action on Friday when first practice for this weekend's Chinese Grand Prix gets underway in Shanghai.

The Diffuser
Brawn BGP001 - rear diffuser design

Brawn have a quite different central channel to their diffuser, with the shape of the deformable structure being used to create a sort of double-decker (black arrows) design. However, the most important and controversial aspect is that to work properly this section of the diffuser needs to be fed by air. Highlighted in yellow, you can easily see the hole in the reference plane (red arrow), which actually starts far further forward than is apparent from the drawing, thanks to the small dimensions of the gearbox. The hole increases the speed of airflow as it heads towards the higher rear venturi section, where it expands and creates more downforce. Other teams are arguing that the presence of the hole is against the regulations.

[Briggykins]

Isn't China usually later in the year?

I usually like rain but I'm actually hoping for a normal race this weekend! Be good to actually get a proper finish. Also looks like Williams are properly in the hunt, on quali performance anyway, so we may get a bit of a race.

[Feek]

I'm really looking forward to this race.

ROFL awesome stuff

Two rubbish drivers respond to Briatore
Friday 17th April 2009

The 'almost-retired' driver of Brawn GP and his 'slow' team-mate have hit back at the incredible outburst of Renault's Flavio Briatore by denouncing the Italian as 'bitter' and a 'bad loser'.

Briatore stunned the paddock on Friday by launching a withering attack on Rubens Barrichello and Jenson Button, telling the Gazzetta dello Sport newspaper: "The drivers in our teams have been and are World Champions, while the Championship is now fought between a driver who was almost retired and another one who is a good guy but a paracarro [the Italian saying for being as slow as a milepost at the side of a road]."

After the 'slow' Button put finishing Practice Two in China as the quickest driver, the Englishman hit back at the Renault boss - and revealed that Briatore had sought to hire him in the winter, presumably as a replacement for the hapless Nelson Piquet jir.

"He needs to remember that he tried to employ me for this year," Button told reporters.

"He is obviously a very angry man after the diffuser issues and he is obviously very disappointed that they haven't produced a car that is as competitive as ours. We have worked very, very hard in very difficult circumstances and it is very, very unfair for Flavio to comment as he has just because he is a little bit bitter."

The response of Barrichello was equally scathing, with the Brazilian observing: "There are plenty of good people in the paddock and plenty of bad losers."

The row also prompted a response from Formula One supremo Bernie Ecclestone, who suggested Briatore should concentrate solely on race matters.

"Its a pity they don't talk more about racing than politics," he said. "We seem to have got a lot of team managers who've become politicians."
