Under the hood, it's running on a 261-hp, 4.0-liter V6 engine. This provides enough torque for towing or off-roading. For the serious adventurer, the available Off-Road package is the ideal choice for a serious quest. In its base trim, the 2012 Nissan Xterra X, it is equipped with 16 steel wheels, remote keyless entry, and power doors and windows. The S, the next upgrade, adds hardcore style and comfort. A first-aid kit is just one of the useful additions in this trim.
