Infiniti's QX4 has finally become more than a gussied up Nissan Pathfinder. A new, more powerful engine absolutely transforms the QX4 for 2001. While the 2000 QX4 struggled to get up to freeway merge speed and demanded drivers plan way ahead on two-lane passing maneuvers, the robust 2001 makes on-ramps fun instead of stressful and two-lane roads playgrounds instead of torture chambers. The 2001 QX4 also features aggressive new exterior styling, a plush new interior and an optional feature or two the competition doesn't yet offer. In spite of all that, Infiniti didn't raise the price over the 2000 model.
