The Nissan Pathfinder goes through a rite of passage in 2005, leaving the kiddie pool to join the big boy SUVs during adult swim. Having grown somewhat outdated, the 2005 Pathfinder gets bigger (six inches longer) and more powerful. Its length means it now offers three rows of seats for the first time. Its power comes from a 4.0-liter 270-hp V6 engine that can tow up to 6,000 pounds. A new 5-speed automatic transmission replaces the old 4-speed.
