Hmm, we wonder if this news will change the way next year’s ‘greenest car’ list will look. From CNet comes word that Honda expects to bring a diesel-powered Honda Accord to the U.S. by 2010.

It gets 62.8 miles a gallon on the highway, but otherwise looks and feels like a regular Accord. At that mileage level, the car is about as “clean” as a new Toyota Prius. But if you run it on biodiesel, a form of diesel made from vegetable oil or animal fat, it would be even cleaner than a Prius (Priuses get 60 in the city).
