Aerodynamics of a bug

[Sandeep]

Here's what we need to do .... does anyone have a video of a bug running down the highway with small peices of yarn taped to the car ? I saw this somewhere once (new beetle I think) and judging by the way the small pieces of yarn react, you'd have an idea of high and low pressure areas ?

I'm still unclear as to how the underpan system would work.

I thought that the reason the Porsche at Lemans a while back flipped was because of air getting under the front of the car ?
