Here's a couple of views of the stacked sections; mimicking the assembled cut foam pieces.
Please note that the door, wheel skirts, and the hood are separated from the main chassis, just as the foam will be, so they can be assembled separately.
I plan on importing this into SketchUp and smoothing it -- this will make the model much smoother and "tighter" so that hopefully I can then do CFD testing; which should give an approximate Cd (coefficient of drag).
