This year at the Denver Auto Show, Jann Scott prowls the convention center floor for “Cafe Standard Automobiles” (Cars that get 28 Miles to the Gallon in the City or better). Jann tracks down the best cars for the environment as well the worst. Some of the top contenders for the Greenest manufactures are first Honda, Toyota, Lincoln, Ford, Mini Cooper, Scion and VW. This year is an all out critique on the industry and who will win and lose in this time of economic crisis.
