I've also seen quite a few things there that are inducing way more drag than they need to.
Especialy the hard transitions on the catamaran designs are inducing quite some additional drag.
The University of Michigan, 'NOVUM' solar race car project team used SIEMENS' CAD/CAM/CFD. This CFD incorporates smoothing protocols to reduce interference drag at component intersections ( minimum fillet radii ), so they have this covered.
Teams which have no access to wind tunnel validation would be locked into whatever CFD could do for them. Hopefully, all their CFD software includes the interference drag minimization code.
