I think the grille / bumper treatment looks like the current Camry, about as innocuous as is possible.
How wimpy is the solar powered A/C going to have to be? If there's been enough advancement in watts per square foot output to run an A/C compressor, there's more than enough to power and drive the entire car if only the hood and trunk are also covered with these pieces of vaporware. There might be enough power to run a flow-through fan when parked with present solar panel technology, but A/C?
And the rear window(s) are unattractive. It is as if Toyota couldn't decide to use small, useful panels like the Insight or CRX, or to completely ugly-up to the Pontiac Aztec sizes, so they settled for useless, and ugly.
