The Grand Che{{{Cherokee is 4 inches longer in wheelbase, about 6 inches longer overall, and 2.5 inches wider in track than the previous model, so it will be more stable in both on- and off-road situations.The all-new Grand Cherokee is built in Detroit using a new steel uniframe construction, a close marriage of a welded steel unit body and underlying front and rear modules, a completely different approach from the new body-on-frame Durango, so although its inside volume and overall size are both similar to the Dodge's, this Jeep is not a clone of the Durango, but a unibody Jeep design through and through.
