The Nissan Armada is powered by a 5.6L V8 engine that makes 317 horsepower and 385 lb-ft of torque via the use of continuously variable valve timing. It comes mated to a 5-speed automatic with tow/haul mode. All three trim levels--SV, SL and Platinum--are available as either rear-wheel drive or 4-wheel drive. Despite its size and massive engine, the Armada is surprisingly responsive. It incorporates anti-lock brakes, active brake limited slip, electronic brake force distribution and brake assist. It also has independent double wishbone suspension front and rear, with the rear being auto-leveling. The Armada comes with standard automatic headlights, heated power outside mirrors and rear sonar for assistance while backing up. The differences between the three Armada styles start with the exterior. The SV sits on 18-inch wheels and includes a body-color grille, while the SL and Platinum get 20-inch rims and a chrome grille. As for the interior, it comes with dual-zone temperature control, rear air conditioning with rear controls, cruise control, 8-way power driver's seat and 4-way power passenger's seat, Bluetooth hands-free connectivity and speed-sensitive windshield wipers. The SL and Platinum trims add standard keyless ignition, power 60/40 third-row seat, leather seats, a power liftgate and wood trim. Exclusive to the Platinum level is the Nissan Hard Drive Navigation System with XM NavTraffic, heated front and second-row seats with memory and a heated, leather-wrapped steering wheel. A Platinum Reserve package adds dark chrome wheels, grille and mirrors, as well as 2-tone chocolate/almond leather seats and dark satin chrome accents to the interior. Room for eight people means there are rear-seat passengers who need entertainment, so the Armada has a CD/MP3 audio system that also features SiriusXM, USB input and Bluetooth. The stereo can be upgraded in the SL and Platinum Armadas to a 12-speaker Bose system that includes a hard disk drive Music Box, a DVD player and wireless headphones.
