The Nissan Xterra is a mid-size SUV that is equally at home on the pavement or barreling down off-road trails. This is possible thanks to its PRO-4X trim, which provides a host of all-terrain features. The Nissan Xterra delivers five passenger seating and a reasonable amount of cargo space, and power comes from a 4.0-liter V6 that generates 261 horses and 281 lb-ft of torque. A six-speed manual transmission is standard, while a six-speed automatic (and four-wheel drive) are optional.
