The 2006 Nissan Xterra come with a 4.0-liter, 265-hp V6 and 4-speed automatic and rear wheel drive. Once you get beyond the base model, the 2006 Xterra offers power features, a roof rack, a Utilitrack unit in the trunk to which you can attach bikes, and a folding front passenger seat for extra-long items, such as skis. ABS, traction, and front airbags are standard across the line. The 2006 Xterra only has two rows of seating, with a folding rear seat for extra cargo room. The trunk itself is made of plastic, for easy washability, and features many hooks and tie-downs. The engine provides a lot of power, and drivers love the rugged strength of the all-wheel drive. Lots of head and legroom make it easy to take friends along.
