The Cayenne has a standard Multi-collision Brake System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Purosangue 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.
Over 200 people are killed each year when backed over by motor vehicles. The Cayenne offers optional Maneuver Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Purosangue doesn’t offer backup collision prevention brakes.
A passive infrared night vision system optional on the Cayenne 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 Purosangue doesn’t offer a night vision system.
The Cayenne offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Purosangue only offers a rear monitor.
Both the Cayenne and Purosangue have Rear Cross Traffic Alert, but the Cayenne has automatic rear cross-traffic braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The Purosangue’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the Cayenne and the Purosangue have standard driver and passenger frontal airbags, 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, blind spot warning systems, rearview cameras and rear cross-path warning.
