Navigator was available either with rear-wheel drive or Fords Control Trac 4-wheel-drive system, which could be left engaged on dry pavement. Automatic self-leveling air-ride shock absorbers went at front and rear on 4x4s, but rear-only on 2WD Navigators. Antilock 4-wheel disc brakes were standard either way. A 3-place, third-row bench seat was installed. A 3-place split middle bench was available at no cost, to expand seating capacity from seven to eight. Towing capacity was 8000 pounds--thats right, a hefty four tons. Sole engine was the larger of Expeditions two V8s: a 5.4-liter, rated at 230 horsepower. Navigators got a special post-assembly inspection, plus a 25-mile preshipment road test. Rivals included the GMC Yukon/Denali, Land Rover Range Rover, and Toyota Land Cruiser. Minimize
