Diffusers: More FIA fussiing

2012-04-09 10:27

Formula 1's governing body, the International Automobile Federation, will probably change the exhaust rules - yet again - for 2013.

Led by technical delegate Whiting, the FIA clamped down hard for 2012 on the sort of "exhaust-blown diffuser" layouts that became common in 2011.

New exhaust layout rules, combined with new restrictions on engine mapping, have made it much more difficult for teams to achieve an aerodynamic effect from the fast-moving hot gases produced by the engine.

FERRARI COMING NEXT


However Whiting said in the FIA's Inmotion magazine: "We are aware that they (the teams) will do as much as they can to direct the exhaust gases down into the area where they want them,"

"I think (the effect) will be 20% of what they had."

Among the cleverest and most effective solutions for the 2012 rules has been seen on the Saubers so Red Bull has followed suit and Ferrari will be next.

Whiting hinted that the 2013 rules would clamp down even harder: "I suspect we'll have to have another go at it in 2013."

'CAN'T BE UNLEARNED'

He admitted, however, that the egg could not be unscrambled. Referring to the jet of high-speed gas emanating from the exhausts near aerodynamic surfaces, Mercedes' Aldo Costa confirmed to Germany's Auto Motor und Sport: "You can't ignore a gift like that."

Whiting explained: "It is a classic case of not being able to unlearn things once they have been invented. The engineers know that there are benefits to be had and there is still some scope for development in this area.

"We can't wipe the memories of the engineers like a computer, can we?"
