What makes you think that it might be, Unobtanium, hmmm?
Because drag is a huge deal, not just punching the hole, but how the rest of the car slides through that hole. For example, the 4th gem Fbody cars were shaped like cheese wedges. Very sharp. Still had more drag than a cx5.
I deal with bullets and trajectory and velocity a good bit. Ogive, base/tail profile, etc. are vastly more important than the tip of the bullet (in fact, it was just recently that through radar tracking, in real time with analysis, that Hornady discovered the ballistic tips were actually melting off of tipped bullets in flight!) A ballistic tip 55gr .223 round has a BC in the high .2s. A hollowpoint 77gr .223, in the mid .3s. But the bt had such a sharp nose...there is so much more at play here...and that's a bullet. With cars you have wheel well air management, underbody air control, side body, the list is huge. Even tire width matters a lot. Then you have the back of the car, which is massively important...gotta make it look good AND low turbulence, unless you're building a prius, and then F looks, apparently.
