The Cayenne Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Atlas Cross Sport doesn’t offer pre-crash pretensioners.
Both the Cayenne Coupe and Atlas Cross Sport have child safety locks to prevent children from opening the rear doors. The Cayenne Coupe 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 Atlas Cross Sport’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 Coupe 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 Atlas Cross Sport doesn’t offer knee airbags.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Cayenne Coupe. But it costs extra on the Atlas Cross Sport.
A passive infrared night vision system optional on the Cayenne Coupe 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 Atlas Cross Sport doesn’t offer a night vision system.
The Cayenne Coupe’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 Atlas Cross Sport doesn’t offer a driver alert monitor.
Both the Cayenne Coupe and the Atlas Cross Sport 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, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.
