FWD is only really any use for light goods on delivery vans. If you don't need the traction of RWD, but might need extra space for cargo, the FWD versions usually have a lower floor in the back thanks to lack of RWD drivetrain.

EcoBoost is just Ford marketing-speak for "turbocharged", so sticking the tag on an already-turbo'd diesel is fairly redundant. It'd just be a badge.
