This semester I'm in a Communications in Physics class, which requires brief "scientific" powerpoint presentations. I figured for my next one I'd talk about the aerodynamics of automobiles with a comparitive analysis of the MCS, MCS with aero pack, and the GP.

So does anyone know where I can get actual information (including some actual numbers) on the aerodynamic differences between these three options?

Also if anyone feels like breaking down the topic of aerodynamics and explaining everything, feel free.
