About Lincoln Navigator

The Navigator had a complete makeover in May 2002 for the 2003 model year, which resulted in a number of modifications and improvements. The Navigator shared a chassis with the Ford Expedition, which was also updated for 2003, although it was differentiated in terms of appearance and premium amenities. The exterior was completely redesigned for the first time since the Navigator’s introduction, with just the front doors and roof panel remaining unaltered from the previous generation. A bigger chrome waterfall grille, brighter quad-beam headlights with larger housings, updated chrome door handles set in color-keyed bezels, and slightly wider running boards were all part of the new appearance. The Navigator had an entirely redesigned instrument panel and dashboard area that was not shared with the Expedition. The instrument panel and dashboard area were decorated with genuine walnut burl wood inlays and panels and switches coated in a low-luster satin nickel hue, inspired by the symmetrical, “dual-cockpit” arrangement of the 1961 Lincoln Continental. White LEDs, totaling 120, added to the upmarket interior design by providing illumination for controls and switches. An articulating door is also included to hide the radio head unit and optional satellite navigation system when they are not in use, in order to draw attention to the high-quality satin nickel-faced analog clock placed in the dashboard.

Other new features and choices for 2003 highlighted the Navigator’s design improvements. Safety was enhanced by new equipment such as Ford’s Safety Canopy side curtain airbags and a tire pressure monitoring system. Power running boards (an industry first), power-folding third row seats, a power liftgate, and HID lighting all added to the convenience (for top end models). The available rear-seat video entertainment system was upgraded to a DVD-based system, and all Navigators now came standard with 18×7.5-inch alloy wheels, with optional 18×8-inch chrome wheels.

The Navigator benefitted from a revised chassis, new rack-and-pinion steering, and an all-new independent rear suspension (IRS), much as the redesigned 2003 Expedition (U222), which improved handling and ride comfort. The Navigator’s load-leveling air suspension was retained, but it now lowered the car by an inch while stopped to make entrance and egress easier. The UN173’s engine was updated for the Navigator, however the 5.4 L DOHC V8 that had previously been marketed under the InTech brand was no longer advertised. However, at 5500 rpm, it now generated 300 horsepower (224 kW) and 355 lbft (481 Nm) of torque, while at 3750 rpm, it produced 355 lbft (481 Nm). The Navigator’s basic curb weight rose to 5,760 lb (2,613 kg) in two-wheel drive versions and almost 6,000 lb (2,700 kg) in four-wheel drive vehicles as a result of the redesign. As a result, towing capacity has decreased somewhat.
