Compare the2022 Porsche CayenneVS 2021 Mercedes AMG GLE

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 AMG GLE doesn’t offer a front passenger side knee airbag.

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 AMG GLE 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.

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 AMG GLE doesn’t offer a night vision system.

Both the Cayenne and the AMG GLE have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

The Cayenne’s corrosion warranty is 7 years longer than the AMG GLE’s (12 vs. 5 years).

Remote Park Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The AMG GLE’s automatic parking system does not offer parking by remote control.
