rear-wheel drive (RWD) or 4WD models. Powertrain In place of the SOHC two-valve version of the 4.6 L Modular V8 shared with the Explorer/Mountaineer and other Ford trucks, the Aviator was fitted with the DOHC four-valve version of the engine, shared with the Mustang Mach 1 and Marauder. Producing and of torque, the DOHC V8 engine in the Aviator came with two more horsepower than the 5.4-L V8 in the Navigator (though with less of torque). As with the Explorer/Mountaineer, rear-wheel drive was standard, with Lincoln offering all-wheel drive as an option; all versions were equipped with a five-speed 5R55S overdrive automatic transmission. Body As with the Mountaineer, the Aviator derived its body construction from the third-generation Explorer, sharing its body structure, doors, and roofline with both model lines. The Aviator adopts a number of styling cues from the second-generation Navigator, which gave it the nickname "Baby Navigator", with visually similar front and rear fasciae, lower door panels/running boards, grilles, and headlamps, and license-plate surrounds. The Aviator was styled with a Lincoln-specific dashboard, adopting a design nearly identical to the Navigator. Styled similar to later-1960s Lincolns, the rectangular-designed dashboard of both models featured an instrument cluster with electroluminescent gauges and needles. The primary visual difference between an Aviator and a Navigator is the lettering on the radio cover panel; an Aviator is lettered "LINCOLN", with its Navigator counterpart lettered "NAVIGATOR". As with the Navigator, the Aviator was given model-specific seats and leather, with American walnut wood trim on the doors and steering wheel. Trim At its 2002 launch, the Aviator followed the trim nomenclature of the LS and Navigator, with a Luxury base trim and Premium top-level trim. For 2004, the Premium trim was renamed Ultimate, matching the Navigator and Town Car. For 2005, the Luxury trim became the sole offering, with previous content remaining available as stand-alone options, including a rear-seat DVD player. An Elite option package was offered, which bundled all features of the Premium/Ultimate trims; the package offered a DVD-based navigation system. Kitty Hawk Special Edition To commemorate the 100th anniversary of the Wright Brothers' 1903 flight at Kitty Hawk, North Carolina, and the 100th anniversary of Ford Motor Company, Lincoln created a "Kitty Hawk" limited edition of the Aviator; it was the official vehicle of the 2003 EAA Countdown to Kitty Hawk.
