Jeep Cherokee's are relatively light. 3300 pounds, about the same as a Prius, or 10% more than a modern honda civic.
I've read about a lot of Cherokee Om617 diesel swaps that are getting 30-35 highway mpg with NO aero modifications. This makes me think that 50 hwy mpg is a not-to-distant reality. The om617 also comes from a car that weighs considerably more, and has similar hp & greater torque than the stock I-6 jeep motor.
Cherokee's are not heavy. They have an engine that is not designed with fuel economy in mind, 4wd, and the aerodynamics of a brick.
With a boat tail (mounted further up on the body thanks to chopped top) and a full belly pan (to cover the mess of parts underneath) I think there are some serious improvements to be made.
City mpg will see huge improvement due to the diesel, but that combined with serious aero mods I think will skyrocket highway mpg from its original 22.
I guess we'll see.
