Neil - nice models ! Is there a way to subdivide them further in SketchUp ?
They look like they have a good poly count now, but they could be a lot smoother.
From what I understand, the models will need to be subdivided many,many times over to be used in a CFD program.
How does SketchUp compare to other 3D apps such as Blender ?

SketchUp has a several good subdivide scripts, but the one that I bought doesn't work with the Kamm back edges -- they get all stretched and scalloped and wonky...
The CarBEN EV model has lots of "hidden" polygons -- the entire battery pack (768 cells) is included, and the five 3D figures, five seats, the steering wheel component, two versions of the doors (open position and closed) -- the model has passed the threshold for my computer to handle it very quickly.
My son is pursuing a plugin for the Half Life 2 game, called Garry's Mod that can directly import SKP files, that will hopefully do CFD. It in effect "drives" the model; rather than simulating a wind tunnel. You give the vehicle "weight" and a "motor" and it then can be "driven". The fellow programing it is specifically intending it to work as aerodynamic analysis. It is a work in progress, so we'll see.
SketchUp is not a solid modeler. It was originally intended for architectural model; which is what I got it for. But there are lots of folks doing all sorts of models with it. As you can see in this thread -- and there are even more incredible models that that. Using SketchUp is quite tactile -- it's fun.

I've been working on a SketchUp model of the Dolphin:
It is slow going because I have to establish all the "hard points" of the overall shape -- and I had to start over once I got the photos with a 6' scale reference. You can't see it from this view but I have the frontal profile and the full side profile done and intersected, and the rear transom is as close as I can get it. And you can see the major arcs on the side and roof are in the model.

Okay, I've been continuing to work on the SketchUp model of the Dolphin:
