Slideshow: Green Wheels of the 2009 Frankfurt Auto Show
This year's Frankfurt Auto Show was an explosion of new green vehicles. With extravagant displays and more than 80 world-premiers, this year's show lived up to its reputation as the auto event to watch. It was also the year of green transportation: we venture to say that no major car show has been more jam packed with electric cars, hybrids, fuel cells, low-carbon diesels, and hybrids of every imaginable species. So take a browse through our slideshow of Frankfurt highlights and pick your favorites.
