It is hard to determine, or really even estimate, what the CRD-8speed numbers will look like as far as mpg, hp, torque. The closest we can use to compare is the international 5spd CRD's being used in europe, australia, etc. However, the emission restrictions will cause some minor tweaks for the USA models. Plus when trying to compare mpg, you get stuck with conversions for imperial gallons, kilometers instead of miles, etc.
Bottom line, it is going to be pretty darn difficult to know any real world numbers for the USA models until Jeep releases those figures.
If I "had" to take a realistic guess, I would expect to see something like 22/28 city/highway mpg when it is finally released.
