With the 2007 redesign, Ford is introducing two versions of its full-size SUV: the Expedition and the Expedition EL (Extended Length). More than two feet longer than the regular Expedition, the EL adds an extra 24 cubic feet of storage space behind the rear seat. Outside, the new Expedition boasts styling cues from the F-150 pickup. Inside is a greatly updated interior, and under the skin is Ford's AdvanceTrac with Roll Stability Control, standard on all models.
