Compare the2024 Porsche Cayenne CoupeVS 2024 Mercedes AMG GLE

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

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 AMG GLE doesn’t offer a night vision system.

The Cayenne Coupe’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 AMG GLE.

The Cayenne Coupe’s standard fuel tank has 1.2 gallons more fuel capacity than the AMG GLE (23.7 vs. 22.5 gallons).

The Cayenne Coupe’s optional launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The AMG GLE doesn’t offer launch control.

For greater off-road capability the Cayenne E-Hybrid Coupe has a greater minimum ground clearance than the AMG GLE (8.2 vs. 7.5 inches), allowing the Cayenne Coupe to travel over rougher terrain without being stopped or damaged. The Cayenne Turbo E-Hybrid Coupe’s minimum ground clearance is 2 inches higher than on the AMG GLE (9.5 vs. 7.5 inches).

The Porsche Cayenne Coupe may be more efficient, handle and accelerate better because it weighs up to about 550 pounds less than the Mercedes AMG GLE.

The Cayenne Coupe has .8 inches more front legroom and 1.4 inches more rear headroom than the AMG GLE.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Cayenne Coupe offers available headlight washers to keep headlight output high. The AMG GLE doesn’t offer headlight washers.

The Cayenne Coupe’s optional Active Parking Assistance can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote ParkAssist 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.
