The Edison2 VLC is tested at the GM wind tunnel only. They also tested it at the the Coastdown testing at the Chrysler proving grounds, and the number they got was 0.157 (if I remember correctly) -- it is withing 2% of the 0.161 "new" SAE Cd from the GM wind tunnel.
If there is any car in the world we have the true CdA of, it is the Edison2 VLC.

Edit: The Dolphin and the E-Tracer are 2 seaters also. The Edison2 VLC is the only 4 seater.
The E-Tracer has better aero than the earlier X-Tracer/Ecomobile.
