Safety Comparison

The S6 has a standard Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The AMG C63 Sedan doesn’t offer a whiplash protection system.

The S6 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 AMG C63 Sedan 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.

The S6 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The AMG C63 Sedan doesn’t offer all-wheel drive.

An active infrared night vision system optional on the S6 Prestige 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 projects the image on the windshield, near the driver’s line of sight. The AMG C63 Sedan doesn’t offer a night vision system.

The S6 offers an optional Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The AMG C63 Sedan only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

To help make backing safer, the S6’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The AMG C63 Sedan doesn’t offer a cross-path warning system.

Both the S6 and the AMG C63 Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, blind spot warning systems, available crash mitigating brakes and lane departure warning systems.

The Audi S6 weighs 463 to 542 pounds more than the Mercedes AMG C63 Sedan. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the S6 its highest rating: “Top Pick Plus” for 2016, a rating granted to only 90 vehicles tested by the IIHS.
