For enhanced safety, the front and rear seat shoulder belts of the Audi A6 Allroad have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Acura RDX doesn’t offer pretensioners for the rear seat belts.
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 RDX doesn’t offer pre-crash pretensioners.
Both the A6 Allroad and RDX 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 RDX’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.
The A6 Allroad has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The RDX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A6 Allroad. But it costs extra on the RDX.
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 RDX doesn’t offer a night vision system.
Both the A6 Allroad and the RDX have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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, rearview cameras, available blind spot warning systems and rear cross-path warning.
The Audi A6 Allroad weighs 406 to 698 pounds more than the Acura RDX. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Audi A6 Allroad is safer than the Acura RDX:

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 A6 Allroad, with its five-star roll-over rating, is 6.1% less likely to roll over than the RDX, which received a four-star rating.
