The predecessor of the Infiniti QX80 was the QX56. Before 2011, the QX80 was noisy and the seats were stiff. In 2011, the new generation QX80 moved to a new platform, and since then the SUV has become comfortable and quiet, and the functions and layout of the cabin have also been completely changed. However, the handling of the new generation QX80 has become a bit clumsy.
 
The fuel consumption of the 400 horsepower, 5.6-liter V8 engine is similar to that of the 5.7-liter engine on the Toyota Sequoia, but the acceleration performance of 100 kilometers is far inferior to the latter. The seven-speed automatic transmission works very linearly. In Consumer Reports' tests, the QX80's all-wheel drive system allows the vehicle to climb challenging steep slopes with ease, and the good passability completely eliminates the concern of running aground. To compensate for the fact that the current QX80 is wider and taller, it often flicks when cornering, and in order to compensate for this shortcoming, the QX80 is equipped with an electronic stability system, but this system is a bit overkill, and it will sacrifice more handling agility when it operates.
 
Drilled into the cabin, the higher driver's seat provides good forward visibility. Although the rear windshield is relatively small, Infiniti's panoramic camera is a useful system that clearly displays a bird's-eye view of the surrounding vehicle in most visual conditions, allowing the driver to easily reverse into storage. The QX80 seat has the visual feeling of a large sofa, and you won't feel too tired after sitting for a long time. The second-row seats can easily accommodate three adults, but the third-row is still unchanged from the previous generation. The position is low and the cushions are short, almost symbolic. The interface on the display is simple, the buttons are large but far away from the driver, and the display is susceptible to light pollution. As a result, even with its many features, it is still not a practical multimedia system.
 
Consumer Reports expects the QX80 to be less reliable in the future. One doesn't need to doubt the engine and transmission, but suspension and electrical problems can be a big problem for owners, and the "Infiniti QX" is very thinly painted, and many of the mottled QX80s are actually new cars that haven't been driven for long.
 
Naturally, there is no problem with the QX80's passive safety capability. Although the screen is not easy to operate, functions such as parking radar, panoramic camera, and cruise control are enough to help the driver avoid danger.
