Cd 0.48

Well, it takes more than small details to bring 0.48 down to 0.30.

But maybe the 0.48 model did not take this in account:

A completely flat underbody.
In Justin W. Martin's CFD presentation,he put the Cybertruck in the neighborhood of Cd 0.36.
I'd like to see an analysis with the front suspension bottomed out at 8-inch ground clearance,and the rear optimized (body raked) for lowest drag highway cruising,ala Ford Probe IV and V concept cars.
