Ecodiesel orders

Good for Ram and I hope the trend continues. This Ecodiesel could be for Ram what the Ecoboost is for Ford. Hopefully it is a reliable engine right off the bat if they continue to sell huge volumes of them. If it turns out to be as popular as the Ecoboost and turns out to be problematic it could be devastating.

Is this an all new engine or is it an engine that has a track record in Europe or someplace else?
