Nissan enters the full-size SUV field for 2004 with a wagon based on its Titan full-size pickup truck. Armada shares Titan's 5.6-liter V8 and 5-speed automatic transmission. It's slightly larger than the Ford Expedition, but weighs several hundred pounds less. It seats up to eight and its 2nd- and 3rd-row seats fold flush with the floor. Armada comes in SE, SE Off-Road, and LE models. Standard are head-protecting curtain side airbags covering all three seating rows. Front side airbags and leather upholstery are optional on SE, standard on the others. Armada offers rear-wheel drive or 4WD that can be left engaged on dry pavement and includes low-range gearing. The automatic transmission has a tow-haul mode. ABS, antiskid/traction control, and a tire-pressure monitor are standard. Load-leveling rear suspension is standard on LE, optional on the others. Armada's liftgate has separate-opening glass. A power liftgate is an exclusive LE option. SE Off-Road includes skid plates, a lower final-drive ratio, and special shock absorbers, plus 17-inch wheels vs. other models' 18s. SE and SE Off-Road have 2nd- and 3rd-row benches for 8-passenger capacity. LEs have 2nd-row bucket seats with a removable center console. The 2nd-row bench is an LE option. Other standard features include power-adjustable brake and accelerator pedals, heated mirrors, running boards, and rear park assist. Options include a navigation system, satellite radio, and rear DVD entertainment. Nissan's upscale Infiniti brand offers a retrimmed version of the Armada as the QX56 with altered styling, slightly more power, and more luxury features.
