The 2004 Lincoln Navigator comes from the SUV's second generation, which was introduced in 2003, and is a full-size luxury SUV. It is powered by a 5.4L DOHC V8 engine that churns out 300 horsepower and 355 lb-ft of torque, mated to a 4-speed automatic transmission. Rear-wheel drive (RWD) is standard, with an available four-wheel drive (4WD). The Navigator was available in Luxury and Ultimate trims, both of which offer tri-zone automatic climate control, power-adjustable pedals, and a parking sensor. Key safety features include dual front airbags, front side airbags, and ABS. The infotainment system features DVD-based Navigation, a 6-disc CD changer, and a premium audio system. For the 2004 model year, Lincoln added a tire-pressure monitoring system as a standard feature.
