Sure sounds like it. Sounds like the 3.2 Powerstroke from the transit family.
Hmmm, Truck Yeah suggests its this Land Rover engine instead (which would make sense since its federalized for light duty trucks) but it sure sounds like the 3.2. I wonder if they are vetting both engines as possible choices? Either way with RAM and Ford in the light duty diesel game GM better get its act together sooner rather than later if it wants to compete in this space, which their recent commitment to diesel engines suggest.
