The 2015 QX80 rides on a body-on-frame
truck chassis, yet this big Infiniti does an admirable job of quelling the harshness that can come with such rugged foundations....
... This is especially true if you spring for the optional Hydraulic Body Motion Control. This feature minimizes body lean in corners and offers a more pleasant ride in general. The standard 400-horsepower V8 has enough gusto to move this rig, just know that it's very thirsty. At highway speeds the Infiniti is hushed, and its 7-speed automatic transmission is refined. As with other full-size SUVs, the QX80 can be a handful in confined parking lots. Thankfully, electronic aids such as the standard Around View camera and front and rear parking sensors ease some of the stress. The Infiniti doesn't have the selectable terrain modes or extreme off-road prowess of a Range Rover or Lexus LX, but does offer high- and low-range modes.
