The Ghibli has standard Anti-Whiplash Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Anti-Whiplash Headrests system moves the headrests forward to prevent neck and spine injuries. The A6 doesn’t offer a whiplash protection system.
The Ghibli has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the A6’s blind spot costs extra.
To help make backing out of a parking space safer, the Ghibli has standard Rear Cross Path, helping the driver avoid collisions. Audi charges extra for Rear Cross-Traffic Assist on the A6.
Both the Ghibli and the A6 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.
