The Quattroporte has standard whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The RS 7 doesn’t offer a whiplash protection system.
The Quattroporte 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 RS 7’s blind spot costs extra.
To help make backing out of a parking space safer, the Quattroporte has standard Rear Cross Path, helping the driver avoid collisions. Audi charges extra for Rear Cross-Traffic Assist on the RS 7.
Both the Quattroporte and the RS 7 have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, daytime running lights, lane departure warning systems and around view monitors.
