Infiniti changed the QX56 name to QX80 from 2014 onward. 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.  Optional for 2014 is Infiniti's Backup Collision Intervention, which emits audible and visible warnings when objects are detected behind the vehicle during reversing maneuvers. The system can also stop the Infiniti to prevent collisions. For 2019, forward collision warning and automatic emergency braking with pedestrian detection are standard. Other updates include standard blind spot warning and a rear-seat reminder system so parents don’t leave children behind when exiting the vehicle. Updates for 2022 include a 12.3-inch infotainment screen, wireless Apple CarPlay compatibility, wireless smartphone charger, and a Bose sound system.
