The Q4 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 VF 8 doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Audi Q4 e-tron are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The VinFast VF 8 doesn’t offer height-adjustable seat belts.
Both the Q4 e-tron and VF 8 have child safety locks to prevent children from opening the rear doors. The Q4 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 VF 8’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.
Both the Q4 e-tron and VF 8 have rear cross-traffic warning, but the Q4 e-tron has Automatic Brake Activation (automatically applies the brakes) to better prevent a collision when backing near traffic. The VF 8’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the Q4 e-tron and the VF 8 have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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.
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 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS. The VF 8 has not been tested, yet.
