I read this topic quite a bit here so here's PUT.com attempt to pencil whip the cost of ownership comparing some gas engine trucks to the new RAM Ecodiesel truck. Link Enjoy...
I think it's been well established that the appeal of this engine or any other diesel is not dollars and cents. Either you want a diesel or you don't. For the Ecodiesel it will boil down to whether drivers prefer the way it drives compared to the Hemi. I would have to just drive the two head to head, preferably towing. I wouldn't bother with any using a stopwatch, we all know the Hemi's gonna win the race. What matters is which engine do you prefer the sound and feel of?
