With the 2011 redesign, the big Infiniti moved to a new platform.
It also became a plush luxury liner with a quiet, well-equipped cabin and a supple, steady ride.
However, its high step-in, ungainly handling, and fuel economy of just 15 mpg overall are detriments.
Standard safety features include stability control, traction control, and antilock brakes.
Options include blind-spot warning, adaptive cruise control with automatic braking and lane-departure warning.
Infiniti changed the QX56 name to QX for 2012 and 2013 model years.
The name changed again to QX80 from 2014 onward.
