R50 specifications

The Nissan R50, also known as the Nissan Pathfinder in many markets, represents a significant evolution in the world of mid-sized SUVs. Produced from 1995 to 2004, the R50 was designed to combine the rugged capabilities of an off-road vehicle with the comfort and practicality required for everyday use.

One of the primary features of the R50 is its body-on-frame construction, which enhances durability while providing better off-road capabilities compared to many of its unibody competitors. This robust design is complemented by a fully independent suspension system, allowing for better handling and ride comfort, especially on uneven terrain. The R50 can accommodate five passengers, with ample cargo space that makes it a favored choice for families and outdoor enthusiasts alike.

Under the hood, the R50 offers a selection of engines that cater to both performance and efficiency. The standard 3.3-liter V6 engine delivers a balance of power and fuel economy, generating around 168 horsepower. For those seeking a more robust driving experience, some variants also featured a 3.5-liter V6 engine that produced up to 250 horsepower. The R50 typically came equipped with a four-speed automatic transmission, although a five-speed manual was available on certain models, allowing for a customizable driving experience.

Technologically, the R50 was ahead of its time, offering features that enhanced both safety and convenience. Available all-wheel-drive systems improved traction and control in various driving conditions, making it suitable for both urban and off-road adventures. Optional features included advanced audio systems, power windows and locks, and other amenities that catered to driver and passenger comfort.

Safety was also a focus, with the R50 equipped with dual front airbags and anti-lock braking systems (ABS) in many models. These features contributed to its solid safety ratings during its production years.

As a versatile SUV, the R50 combines style, comfort, and capability. With its blend of ruggedness and modern features, the Nissan R50 continues to be a beloved choice among SUV enthusiasts, embodying Nissan's commitment to quality and innovation in the automotive industry. Whether tackling rough trails or cruising on city streets, the R50 remains a testament to Nissan's engineering excellence.
