According to an F1-Live story, the FIA is considering a ban on the winglets and flip-ups that have sprouted from F1 cars over the last few years. This has to be a step in the right direction, considering the strange growths seen in testing in Barcelona, McLaren’s over-the-nose wing and Honda’s bunny ears.
The big problem is going to be in defining what is an aerodynamic protuberance and what isn’t. As can be seen from the above shot of last year’s Renault R26, there are bulges and extrusions all over the outer surface of modern cars, most of which are primarily aerodynamic in intent. But some are caused by what lies underneath – the blisters above the rear suspension mounting points on the Renault are an example. So how are the FIA to draw a line and say that’s the limit?
All those obvious winglets on the body would have to go but the flip-ups are more problematic; at what point do they cease to be a necessary part of the body and become aerodynamic extensions? Barge boards and the increasingly-complex additions to the front wing could perhaps be outlawed – but who is to say what is part of the wing and what is an addition?
It could be a thorny problem and has the potential to involve the governing body in complicated discussions for years. But they are right in that something needs to be done. Although aerodynamic extensions have increasingly been sprouting from the cars over the years, this year’s engine freeze and consequent saving of money has ensured that the extra cash goes into aerodynamics instead. The result is an acceleration of such developments and yet more problems with overtaking as the cars become completely dependent upon clean air to function properly.
I have been saying for some time that it is not the car that needs to have its wings clipped – it’s the science of aerodynamics. Extend the flat bottom to eliminate the raised nose, consider getting rid of wings completely, and you leave the aerodynamicist very little with which to work. That may be what the FIA will be forced to do in the end, instead of trying to define what bits are allowed where and how big they can be. Simplification is what they should be aiming for, not endless complication.
