The A5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Crown doesn’t offer pre-crash pretensioners.
Both the A5 and Crown have child safety locks to prevent children from opening the rear doors. The A5 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 Crown’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.
The A5 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Crown doesn’t offer front seat center airbags.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Audi A5 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 Toyota Crown has not been tested.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The A5 has Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Crown doesn’t offer a system that can receive automated systems from infrastructure.
To help make backing out of a parking space safer, the A5 has standard Rear Cross-Traffic Assist with Automatic Brake Activation, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the Crown Limited/Platinum/Nightshade offers Parking Support Brake.
Both the A5 and the Crown have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee 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, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert 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 A5 is safer than the Crown:

The Audi A5 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 Crown has not yet been fully evaluated by the IIHS for 2025.
