The Nissan Pathfinder and Terrano are mid-size SUVs. Where as the Pathfinder is sold in North America, the name first introduced in 1986, elsewhere in the world the vehicle was known as the Terrano. Currently, the Pathfinder falls between the Xterra and Murano in the lineup. The first generation Pathfinder/Terrano platform is known as the WD21. The second generation Pathfinder platform is known as the R50.
The North American first generation Pathfinder came in two different body styles. From 1986 to 1989 Pathfinders came in a two door body. In 1990 the body changed to a four door. Some 1990 Pathfinder's came with the two door body, but they are rare. From 1986 to 1989 Pathfinders were available with either the Nissan VG30I V6, or the Z24 I4. In 1990 the V6 received an upgrade from throttle body injection to a multi point fuel injection system. This engine was known as the VG30E, and was rated at 153 hp and 180 lb/ft torque.
The first generation continued until 1995. The second generation was introduced in 1996 with more rounded styling. The second generation pathfinder was completely redesigned from the first generation, switching from frame on body construction to uni-body construction. For the 1999 1/2 model year, the Pathfinder was freshened. 2001 brought a new 240 hp (179 kW) V6 engine, the VQ35DE.
At the 2004 North American International Auto Show, Nissan unveiled a completely redesigned Pathfinder for the 2005 model year. The new Pathfinder uses the Nissan F-Alpha platform, and is powered by a 4.0 L V6 engine VQ40DE (270 hp, 291 ft·lbf).
Until 2003, most Pathfinders were built in Japan, before shifting production to Smyrna, Tennessee. In late 2003, a full-size SUV, the Pathfinder Armada, debuted. Although they share a common name, they have little similarity and use different platforms. The Armada no longer uses the "Pathfinder" prefix. The Pathfinder is sold as the Terrano in many markets outside of North America. In 2005, a redesigned Pathfinder was released and the Pathfinder name became international as it sold worldwide.
