The A6 Allroad’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Nautilus doesn’t offer pre-crash pretensioners.
Both the A6 Allroad and Nautilus have child safety locks to prevent children from opening the rear doors. The A6 Allroad 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 Nautilus’ 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 A6 Allroad. But it costs extra on the Nautilus.
A passive infrared night vision system optional on the A6 Allroad Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Nautilus doesn’t offer a night vision system.
Both the A6 Allroad and the Nautilus have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear 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, rearview cameras, available blind spot warning systems and rear cross-path warning.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the A6 Allroad, with its five-star roll-over rating, is 6.6% less likely to roll over than the Nautilus, 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 A6 Allroad its highest rating: “Top Pick Plus” for 2021, a rating granted to only 73 vehicles tested by the IIHS. The Nautilus is only a standard “Top Pick” for 2021.
