The 2006 Nissan Xterra is part of the second generation for the model, offering a more powerful, rugged, and off-road focused SUV compared to its predecessors. Nissan equipped this year's Xterra with a standard 4.0L V6 engine, delivering 265 horsepower coupled with either a 5-speed automatic or 6-speed manual transmission. Most models carry RWD as standard, while a part-time 4WD is available for tackling challenging terrains. Four trims: X, S, Off-Road, and SE, provide varying levels of comfort and off-road superiority. For safety features, Nissan offered ABS, electronic brake-force distribution, and stability control as standard. Inside, the Xterra includes a basic yet functional infotainment system that lacks the modern-day flashy tech but fits well with the sturdy demeanor of the vehicle. It's known for its utilitarian design, impressive off-road capability, and solid build.
