Ten Most Polluting Vehicles

Forbes put together a list of the top 10 worst auto polluters, although the actual list is hard to find in the article (check out the slideshow). It's not a surprise that most of the top 10 are SUV's or diesel-powered vehicles. One good news is that new diesel vehicles starting with 2009 models will be more efficient, thanks to new auto technology. These cars also abide by new California emissions laws, which proves that car companies can respond to new emissions legislation if necessary.
