The LX has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The QX80 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the LX. But it costs extra on the QX80.
When descending a steep, off-road slope, the LX’s standard CRAWL Control allows you to creep down safely. The QX80 doesn’t offer CRAWL Control.
The Lexus LX’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Infiniti QX80 does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
Both the LX and QX80 have rear cross-traffic warning, but the LX has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The QX80’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the LX and the QX80 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
