I don't know what "QX" stands for -- but there should be a second "X." The 2006 Infiniti QX56 4x4 is double extra large, double luxurious and double S-E-X-X-Y. With a base price of $52,550 ($55,300 as tested including a $1,200 sunroof, $800 intelligent cruise control and a $750 destination charge), the 2006 Infiniti QX56 4x4 comes with a 4 year/60,000 mile basic warranty, a 6 year/70,000 mile powertrain warranty and an EPA estimate of 13 mpg city/18 mpg highway. Round up six close friends, and let's drive.
