Hi Vman, my 30 mph and 60 mph were just some random figures, just for some scale in my comparison.
I was comparing ideal teardrops / raindrops. Those do get laminar flow, don't they?
As far as I can project my comparison to full-size cars: I would imagine that two different shapes could have similar flow attachment at a low speed (thus similar Cd), but vastly different attachment at high speeds...?
