Both the new Q5 Sportback and QX55 have child safety locks to prevent children from opening the rear doors. The new Q5 Sportback has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The QX55’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Audi new Q5 Sportback achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Infiniti QX55 has not been tested.
The new Q5 Sportback has standard Secondary Collision Brake Assist, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The QX55 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.
When descending a steep, off-road slope, the new Q5 Sportback’s standard Hill Descent Control allows you to creep down safely. The QX55 doesn’t offer Hill Descent Control.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The new Q5 Sportback has Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The QX55 doesn’t offer a system that can receive automated systems from infrastructure.
The Audi new Q5 Sportback offers an optional Top View Camera System and it also offers an optional rear camera washer to make backing always safe, regardless of road dirt or grime, while the Infiniti QX55 doesn’t offer a camera washer, requiring manual cleaning.
Both the new Q5 Sportback and QX55 have rear cross-traffic warning, but the new Q5 Sportback has Rear Cross-Traffic Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The QX55’s Rear Cross Traffic Alert doesn’t automatically brake.
The new Q5 Sportback’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The QX55 doesn’t offer a driver alert monitor.
Both the new Q5 Sportback and the QX55 have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, 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 and available around view monitors.
Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Audi new Q5 Sportback is safer than the QX55:

The Audi new Q5 Sportback has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The QX55 is not even a standard “Top Safety Pick” for 2025.
