FIA to clear up diffuser controversy

Several teams could be forced to use different diffusers in Australia as the FIA is finally set to issue clarification about the controversial designs.

Last year's Australian Grand Prix was dominated by the double-decker diffuser row which saw Brawn GP, Williams and Toyota famously steal a march on their rivals.

All the other teams have since adopted the design, but some have taken it a step further by adding an extra layer to the diffuser and exploiting the hole where the external engine starter fits.

Article 3.12.7 in the FIA rule book states: 'A single break in the surface is permitted solely to allow the minimum required access for the device referred to in Article 5.15. [supposed to refer to starter motor, although this is Article 5.16].'

However, the FIA is set to clear the issue up once and for all after its technical chief Charlie Whiting inspected all cars during this weekend's season opener in Bahrain.

It could mean that some teams will be forced to use different designs in Australia in two weeks' time.

McLaren team principal Martin Whitmarsh confirmed Whiting's visit, but insists there's nothing wrong with their car.

"I think Charlie came down and looked at all the cars in that area, but I am not aware that anyone had any action taken against them over it," he is quoted on Autosport. "There were some concerns expressed.

"There is a discussion between all the teams about what we are going to do. There are holes in the diffuser for the starter, the hole in ours is no bigger than the one on the Championship winning car last year. And also no bigger than it is on about four other cars."
