Supposedly, Jeep Liberty will soon be available with a VM Motori 4 cyl,
good for around 30mpg, but I don't know exactly when. A little short,
but might be OK. Detroit Diesel bought VM shortly before Penske sold out
to DCX. I don't know much about them other than that.

Disclosu I work for a supplier of one of the above named companies.

That is a sure thing. The diesel Liberty will be available late this year.
The VMI engine is a 2.8L turbo-diesel, which has been in use in Europe (not
in a Chrysler product) for awhile. I plan to get one. I drive a 3.7L
Liberty now and love it. Would love it more with higher fuel economy.

Disclosu I work for DCX.
