Im really interested about this vent on the front of the red bull!
Here is what Gary Anderson thinks about it!
(stolen from bbc website)
"The pictures Red Bull have released do not show a great deal. For a team running at the front, it's always hard to make a big step forward. Everything looks that little bit tidier, especially around the rear end, and while it has a similar front nose to many other cars, it's nicely rounded and blended. But the big intrigue is the hole in the nose where the step is in the area of the front suspension. It looks like there is an air duct in there, but where does the air go? It could be for cooling, perhaps of the Kers unit and batteries. That is an area where Red Bull had problems last year. Or it could exit out of the rear for an aerodynamic effect. The issue is that you have to go a long way backwards in the car - to the fuel tank area at the earliest - before the rules let you have a hole big enough to exit that amount of air."
