The Lincoln Navigator is a full-size luxury SUV built by the Ford Motor Company for its luxury division, Lincoln. Lincoln introduced the Navigator in August of 1997 as a 1998 model,[1] the same year as the redesigned Lexus LX. The Navigator was Lincoln's first SUV as well as its first four-wheel drive capable vehicle. The Navigator shares a platform, mechanical features, and other equipment with the Ford Expedition, which was introduced one year before it. Unique and upscale styling, interior materials, and other features differ the Navigator from the Expedition. Given its platform mate, the Navigator is the largest vehicle Lincoln currently offers, having the greatest cargo capacity and seating for seven to eight people, depending on the model. For 2007, a longer, extended wheelbase version of the Navigator called the Navigator L was introduced, increasing cargo capacity further. Since its introduction, Lincoln has offered only one engine choice at a time in the Navigator in any model year; all are variations of Ford's 5.4 L Modular V8.(Wikipedia)
