diesel power

Why doesn't Ford make a small SUV with a diesel in it? I think they would sell well, due to fuel economy, power and durability. Similiar to the Jeep Liberty in 2005-06. I bought one because Ford didn't offer one.

Recently bought a 2014 Escape with the 1.6L engine and front wheel drive.  Great vehicle.  At this time the mileage is in the 29 to 31 mpg.  I would love the 1.6 tdi diesel that Ford said recently got 85 mpg in a European Focus.  Perhaps in an Escape it might get 65 to 70 mpg.
