This year's Frankfurt Motor Show was quite an eye-opener. We saw plenty of highly efficient diesels, futuristic electric vehicles and plug-in electric hybrids, and even some spectacular supercars. The unveilings revealed more than just metal. They showed that the worldwide auto industry just might be making a comeback. Unfortunately for you Yanks, many of the vehicles uncovered in Germany will never leave Europe. So, we thought it would be nice to give you a view of what you will probably never be able to drive on your native soil. Cheers.
