Based on the F-150 pickup truck, Expedition gave Ford a serious challenge in the full-size sport-utility market. Available with either 2- or 4-wheel drive, Expedition was available only with 4-doors and was about five inches longer than a Chevy Tahoe or GMC Yukon. Seating for six was standard in the SLT model. An optional 3-place third seat gave Expedition seating for nine. The second-row bench seat folded flush to the floor, in a simple one-step process. Front captain's chairs went into the top-of-the-line Eddie Bauer edition, for 5-passenger seating. Leather upholstery was standard in the Eddie Bauer, which could also have the optional third seat. The standard suspension used coil springs at all four corners. Rear air springs and front air shock absorbers were optional on 4x4 models. Rear air springs were optional on 4x2 Expeditions. A 215-horsepower 4.6-liter V8 engine was standard. Optional: a 230-horsepower, 5.4-liter V8. Both engines drove a 4-speed automatic transmission. Dual airbags, antilock brakes, and height-adjustable shoulder belts for outboard front and second-row seats were standard. Control Trac in 4-wheel-drive models had four drive settings: 2WD, automatic 4WD; 4WD High (for slippery conditions); and 4WD Low (for heavy-duty off-roading).
