2005 Jeep Liberty Sport 4WD 4dr SUV (2.4L 4cyl 6M)
Best fuel economy in a 4WD in the US. Diesel has great power all the way to 11,000 ft. elevations on mountain passes. Best 4WD I've ever owned for winter driving. Diesel performs marvelously off-road. Without serious suspension modification (at least a 2.5"-3.0" lift) and larger tires (245/75R 16 would be ideal), though, it lacks adequate ground clearance for anything but mild off-highway use. A Subaru Forester has much better ground clearance. As noted the factory tires are crap. EGR valve failures are a common problem, though mine have lasted pretty well. Fuel economy ranges from 16 mpg in dead winter starts and stops to 31-32 mpg on highway at speeds 65 mph or less.
CRD engine. Fuel economy is great all- around. Diesel engine/tranny combo is superior off-road, and still manages good fuel economy in that use. Selec- trac is great for winter driving.
Stock suspension is garbage, as are factory tires. Front springs are inadequate for engine weight and will start bottoming out at some point. Grossly inadequate stock ground clearance (about 6.5") for serious backcountry use. Look at a Frankenlift CRD suspension lift kit if you plant 4- wheel much.
