The 2014 Nissan Xterra S 4X4 is a rugged, body-on-frame SUV built for serious off-road adventures and utilitarian durability. Powered by a robust 4.0-liter V6 engine producing 261 horsepower, it features a part-time four-wheel-drive system and a 5-speed automatic transmission, making it well-suited for trails, mountains, and rough terrain. The S trim includes essentials like Bluetooth connectivity, steering wheel-mounted audio controls, and a roof rack with gear storage, while maintaining a straightforward, easy-to-clean interior ideal for outdoor enthusiasts. Though its fuel economy is modest at around 20 mpg highway and the cabin materials feel dated, the Xterra S 4X4 stands out as one of the last true off-road-capable SUVs in its class.
