The Cayenne’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Purosangue doesn’t offer pre-crash pretensioners.
The Porsche Cayenne has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Purosangue doesn’t offer knee airbags.
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 has standard 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.
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, front side-impact airbags, side-impact head 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, rear cross-path warning and driver alert monitors.
