During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The ATS-V doesn’t offer a whiplash protection system.
The XF R-Sport/S has standard Autonomous Emergency Braking, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The ATS-V offers an available collision warning system without the automated brake feature which would prevent or reduce the collision if the driver fails to react.

The XF’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The ATS-V’s standard manually variable intermittent wipers have to be constantly adjusted.
