The Q4 e-tron Sportback’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 Q4 e-tron Sportback and bZ4X have child safety locks to prevent children from opening the rear doors. The Q4 e-tron 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 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 Q4 e-tron Sportback. But it costs extra on the bZ4X.
Both the Q4 e-tron Sportback and the bZ4X have standard driver and passenger frontal airbags, front side-impact 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, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
The Audi Q4 e-tron Sportback weighs 419 to 617 pounds more than the Toyota bZ4X. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Q4 e-tron Sportback its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 101 vehicles tested by the IIHS. The bZ4X has not been tested, yet.
