The Q8 e-tron’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The bZ4X doesn’t offer pre-crash pretensioners.
Both the Q8 e-tron and bZ4X have child safety locks to prevent children from opening the rear doors. The Q8 e-tron 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 bZ4X’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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q8 e-tron. But it costs extra on the bZ4X.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The Q8 e-tron has Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The bZ4X doesn’t offer a system that can receive automated systems from infrastructure.
Both the Q8 e-tron and the bZ4X 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, 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 available around view monitors.
The Audi Q8 e-tron weighs 1334 to 1808 pounds more than the Toyota bZ4X. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Audi Q8 e-tron is safer than the Toyota bZ4X:

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Q8 e-tron, with its five-star roll-over rating, is 2.4% less likely to roll over than the bZ4X, which received a four-star rating.
The Audi Q8 e-tron achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The bZ4X is not a “Top Safety Pick” for 2024.
