Everything has been explored, there are no more trails to blaze, and Nissan has found all the paths. The name remains, but the new Pathfinder is no rugged adventure junkie. Now it’s a carlike, three-row, seven-seat, unibody crossover with the inevitable VQ-series 3.5-liter V-6 transversely mounted under its hood. Coming off the same Tennessee assembly lines that screw together the Infiniti JX35, it’s essentially a Nissan-branded version of that machine, but with its own sheetmetal. It’s perfectly suited to buyers for whom adventure is getting lunch one day a week at Jersey Mike’s instead of Subway.
