9. Porsche Panamera
Take a drive in the Panamera and you’ll quickly forget that it seats four adults very comfortably. Yes, automakers have tried to make a four-door sports car before, but none could come close to the performance of the new Porsche Panamera. In one vehicle you can have a family sedan, sports car and now with the 2012 Porsche Panamera S Hybrid, you can even experience all that while enjoying better fuel economy.
