Car and Driver is reporting the EPA estimates for the Ecodiesel Ram, they are pretty great

Why small[ish] diesels in light[ish] trucks its a GREAT idea.S

Its about time we started getting trucks with pulling power AND decent mileage. Rumor is the new F150 will get close, but not while towing, thats for sure. There are problems with a diesel engine (mostly costs) but if I can get 20 city and 28 highway, and probably as good as 18 with a load....I'm sold.
