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 Levante 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 Levante 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 Levante 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 Levante doesn’t offer a night vision system.
The Cayenne’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Levante.
Both the Cayenne and Levante have rear cross-traffic warning, but the Cayenne has Rear Cross Traffic Alert (automatically applies the brakes) to better prevent a collision when backing near traffic. The Levante’s Rear Cross Path doesn’t automatically brake.
Both the Cayenne and the Levante have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
