Ford has announced a C-Max Energi concept car that gets a substantial amount of its electricity from solar. There was a lengthly and interesting article on it published in CleanTechnia.com. There is also a Ford press release on the solar concept C-Max Energi. It seems to make more sense to put solar panels on your roof, but maybe this would work for someone.
