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.
When descending a steep, off-road slope, the A6 Allroad’s standard Hill Descent Control allows you to creep down safely. The Nautilus doesn’t offer Hill Descent Control.
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, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, around view monitors, available blind spot warning systems and rear cross-path warning.
