The QX56 is a big, plush, gas-thirsty Sport Utility Vehicle forged in the tradition of the Lincoln Navigator and Cadillac Escalade. Derived from the Nissan Armada platform, the QX56 is heavily adorned in chrome with a bold front grille and huge projector-beam headlights. Inside, rich leather seating provides space for up to eight passengers, and every amenity imaginable is either standard or part of the option list. Though the interior is not as meticulously detailed as a Range Rover or Navigator, the QX56 does an acceptable job disguising its utilitarian roots.
