A new engine and transmission highlight 2005 updates to Lincoln's Ford Expedition spinoff. Navigator comes in Luxury and Ultimate models. New for '05 is a revised 5.4-liter V8 that provides the same 300 hp as its predecessor, but is designed to deliver more low-range power. Also for '05, a 6-speed automatic transmission replaces the standard 4-speed unit. Offered are rear-wheel drive or Ford's ControlTrac 4WD that can be left engaged on dry pavement and includes low-range gearing. ABS, antiskid/traction control, self-leveling air-spring suspension, and 18-inch wheels are standard. Power-adjustable pedals, leather upholstery, heated power-folding door mirrors, and a CD changer are also standard. So are head-protecting curtain side airbags for the 1st and 2nd seating rows. Second-row seating is a choice of two buckets with a center console or a 3-passenger split folding bench. The 3rd row has a 60/40 split folding bench; standard on Ultimate is a power-folding feature for each section. Ultimate also has a standard power liftgate and optional power running boards that automatically extend when a side door opens. Heated and cooled front seats are standard on Ultimate, optional on Luxury. For 2005, the antiskid system includes Ford's Roll Stability Control, which is designed to detect an impending tip and activate the antiskid system to reduce chances of a rollover. A navigation system is optional on Ultimate, and rear DVD entertainment is available for both models.
