A passive infrared night vision system optional on the Panamera 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 and even aims one of the vehicle’s headlights in the direction of the person or object. The AMG GT 4-Door doesn’t offer a night vision system.

Both the Panamera and the AMG GT 4-Door have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

The Panamera 4 E-Hybrid can drive on battery power alone for up to 14 miles. The AMG GT 4-Door must run its internal combustion engine to move.

Regardless of its engine, Regenerative brakes improve the Panamera’s fuel efficiency by converting inertia back into energy instead of wasting it (mild regeneration on non-hybrids). Mercedes only offers a regenerative brake system on the AMG GT 4-Door 53.

The Panamera E Hybrid’s standard fuel tank has 3.7 gallons more fuel capacity than the AMG GT 4-Door (21.1 vs. 17.4 gallons), for longer range between fill-ups. The Panamera’s standard fuel tank has 6.3 gallons more fuel capacity than the AMG GT 4-Door (23.7 vs. 17.4 gallons).

The Panamera offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The AMG GT 4-Door doesn’t offer an active sway bar system.

The Panamera offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Mercedes doesn’t offer an active suspension on the AMG GT 4-Door.

The Panamera’s front to rear weight distribution is more even (51.2% to 48.8%) than the AMG GT 4-Door’s (54% to 46%). This gives the Panamera more stable handling and braking.

For better maneuverability, the Panamera w/Rear Axle Steering’s turning circle is 2.6 feet tighter than the AMG GT 4-Door’s (37.4 feet vs. 40 feet).

The Porsche Panamera may be more efficient, handle and accelerate better because it weighs up to about 500 pounds less than the Mercedes AMG GT 4-Door.

The front grille of the Panamera uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The AMG GT 4-Door doesn’t offer active grille shutters.

The Panamera offers available computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The AMG GT 4-Door doesn’t offer active noise cancellation.

To improve rear visibility by keeping the rear window clear, the Panamera offers an optional rear wiper. The AMG GT 4-Door doesn’t offer a rear wiper.
