It's always fun to see mods for the Volt. Your treatments extend the obvious future personalization of the new marque. I always thought it was a (unfortunate terminal patient) Saturn shoe-in. Also ironically the (another dying brand) Pontiac bowling balls were a great fit for your concept.
My fun contribution is a larger version midsize sedan with extended Gran Torino-esque rear flanks. The large grille front has only the vestigial details (can they work as beneficial vortex generators?) The lower grill opening has adjustable vanes for blocking/cooling or active aero control.
The aftermarket better start sharpening their (digital) pencils for more tested aero-centric parts for all the new concepts/production models (if they want to survive) coming down the pike.
