2006: The flexing front wings
The first real discussion subject of 2006 was without a doubt the flexing front wing of Ferrari. Although most wings bend down a little bit at higher speeds because of the air pressure, Ferrari found a very distinct solution to optimise their performance. As the 2006 cars were really underpowered in relation to the grip levels, aerodynamic drag was a vital part for topspeeds, more than has ever been. As the upper element of the wing would prevent flexing, Ferrari allowed movement so that the wing's upper planes would detach from the nose cone at higher speeds. This marginal decrease in drag and downforce no doubt gained a bit of topspeed until eventually the FIA kindly requested Ferrari to redesign the attachment.
Why stop at flexible wings? How about flexible radiator air inlets. Wouldn\'t that make a larger gain in aero efficiency than a flexing wing? It would be easier to hide as well.
