Here's the
Fully Charged episode that gives an excellent glimpse into the Trev - that has already been driven around the world!
I hope that they build a Trev v2.0, to address the Cg and possibly improve the Cd, as well. They've shown the strengths of this design, and they are open and honest about the weaknesses. I hope they will release dimensional drawings and/or 3D CAD models.
