Riding on Ranger's chassis but toting the body of an Explorer wagon, Ford's unique Sport Trac works as both truck and wagon. It looks like Explorer from prow to the back of the second side door, but then the wagon's enclosed cargo compartment gives way to a sawed-off pickup bed. That back box, crafted from sheet-molded composite plastic, extends for 50 inches. Inside, four full-size doors make entry easy from any seat, and the seat system has two front buckets and a back bench that splits and folds to form a brief cargo bay. Sport Trac draws power from Ranger's single-cam 4.0-liter V6 engine. Optional 4WD traction is offered with a dashboard switch to shift easily from rear 2WD to 4WD high gear or into four-wheel low for off-road travel. For 2003 there are three trims available with XLS, XLT and XLT Premium. A refreshed cabin adds low-back bucket seats, while Ford's Safety Canopy headliner air bag system is a new option. The latest special edition is called Adrenaline, containing a 485-watt Pioneer audio system, plus special wheels and unique color schemes.
