The GX 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, Full-Time Four-Wheel Drive is standard on the GX. But it costs extra on the QX80.

When descending a steep, off-road slope, the GX Overland’s standard Downhill Assist Control allows you to creep down safely. The QX80 doesn’t offer Downhill Assist Control.

Both the GX and QX80 have rear cross-traffic warning, but the GX has Rear Cross-Traffic Braking (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 GX 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, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The GX has a standard locking fuel door. The fuel filler door is not lockable on the QX80. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

The GX stops shorter than the QX80:

The GX has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the QX80; it requires you to depend on a temporary spare, which limits mileage and speed before replacement.

The GX Overtrail has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The QX80 doesn’t offer an active sway bar system.

For better maneuverability, the GX’s turning circle is .6 feet tighter than the QX80’s (39.4 feet vs. 40 feet).
