What I meant was what if an F1 team of designers didn't have to be constrained by any rules and could build their dream F1 car. For example, there was one car a couple of decades ago (I think early 80's maybe?) that used a sort of vaccum effect to keep the car sucked to the ground. It improved cornering speeds greatly, but the device was banned.

I googled some and found this: http://www.pistonheads.com/gassing/topic.asp?h=0&t=598933&hw...

Couldn't find a link to the original article though. Pretty interesting.
