The 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 Aviator doesn’t offer pre-crash pretensioners.
The e-tron Sportback’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Aviator doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the e-tron Sportback. But it costs extra on the Aviator.
An active infrared night vision system optional on the e-tron Sportback helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The Aviator doesn’t offer a night vision system.
Both the e-tron Sportback and the Aviator 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 National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Audi e-tron Sportback is safer than the Lincoln Aviator:
| 
 | e-tron Sportback | Aviator | 
| 
 | Front Seat | |
| STARS | 5 Stars | 5 Stars | 
| HIC | 44 | 65 | 
| Chest Movement | .7 inches | .9 inches | 
| Abdominal Force | 117 lbs. | 161 lbs. | 
| 
 | Rear Seat | |
| STARS | 5 Stars | 5 Stars | 
| Hip Force | 579 lbs. | 604 lbs. | 
| 
 | Into Pole | |
| STARS | 5 Stars | 5 Stars | 
| Max Damage Depth | 8 inches | 12 inches | 
| HIC | 279 | 288 | 
New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.
Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the e-tron Sportback, with its five-star roll-over rating, is 5.5% to 5.9% less likely to roll over than the Aviator, which received a four-star rating.
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 e-tron Sportback its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 89 vehicles tested by the IIHS. The Aviator is only a standard “Top Safety Pick” for 2022.
