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 Wrangler doesn’t offer pre-crash pretensioners.
Both the Cayenne and Wrangler 4-door have child safety locks to prevent children from opening the rear doors. The Cayenne has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Wrangler’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The Porsche Cayenne has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 Wrangler 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 Wrangler 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 Wrangler 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 Wrangler doesn’t offer a night vision system.
The Cayenne’s 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. The Wrangler doesn’t offer a lane departure warning system.
The Cayenne has a standard Surround View to allow the driver to see objects all around the vehicle on a screen. The Wrangler only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
The Porsche Cayenne’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Jeep Wrangler does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
The Cayenne 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. A system to reveal vehicles in the Wrangler’s blind spot costs extra.
To help make backing out of a parking space safer, the Cayenne has standard Rear Cross Traffic Alert and automatically engage the brakes. Jeep charges extra for Rear Cross Path Detection on the Wrangler and the Wrangler’s Rear Cross Path Detection does not include automatic braking.
The Cayenne’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Wrangler doesn’t offer a driver alert monitor.
For better protection of the passenger compartment, the Cayenne uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Wrangler uses a body-on-frame design, which has no frame members above the floor of the vehicle.
Both the Cayenne and the Wrangler have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and rearview cameras.
