An annual ranking of the "greenest" and "meanest" cars sold in the United States found that no American vehicles got the best grades -- those all went to Japanese carmakers. The worst score, meanwhile, went to a newcomer on the list: the diesel version of VW's Touareg SUV.
Ah, it’s been that way for awhile. The Excursion topped the meanest list, then the H2. But I was not expecting a diesel to top the list this year, disappointing.
