Safety

Both the Panamera and AMG C 63 Sedan have child safety locks to prevent children from opening the rear doors. The Panamera offers optional 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 AMG C 63 Sedan’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 Panamera offers available whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The AMG C 63 Sedan doesn’t offer a whiplash protection system.

The Panamera offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The AMG C 63 Sedan doesn’t offer all-wheel drive.

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 C 63 Sedan doesn’t offer a night vision system.

Both the Panamera and the AMG C 63 Sedan have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee 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, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

Fuel Economy and Range

The Panamera 4 E-Hybrid can drive on battery power alone for up to 31 miles. The AMG C 63 Sedan must run its internal combustion engine to move.

An engine control system that can shut down half of the engine’s cylinders helps improve the Panamera Turbo’s fuel efficiency. The AMG C 63 Sedan doesn’t offer a system that can shut down part of the engine.

Regenerative brakes improve the Panamera’s fuel efficiency by converting inertia back into energy instead of wasting it. The AMG C 63 Sedan doesn’t offer a regenerative braking system.

Tires and Wheels

For better traction, the Panamera has larger standard tires than the AMG C 63 Sedan (F:265/45R19 & R:295/40R19 vs. F:245/40R18 & R:265/40R18). The Panamera’s optional tires are larger than the largest tires available on the AMG C 63 Sedan (F:275/40R20 & R:315/35R20 vs. F:245/40R18 & R:265/40R18).

The Panamera’s optional 315/30R21 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the AMG C 63 Sedan’s optional 35 series tires.

For better ride, handling and brake cooling the Panamera has standard 19-inch wheels. Smaller 18-inch wheels are standard on the AMG C 63 Sedan. The Panamera’s optional 21-inch wheels are larger than the 19-inch wheels optional on the AMG C 63 Sedan.

Suspension and Handling

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 C 63 Sedan 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 C 63 Sedan.

The Panamera has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Panamera’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The AMG C 63 Sedan doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Panamera’s wheelbase is 4.3 inches longer than on the AMG C 63 Sedan (116.1 inches vs. 111.8 inches). The Panamera Executive’s wheelbase is 10.2 inches longer than on the AMG C 63 Sedan (122 inches vs. 111.8 inches).

For better handling and stability, the average track (width between the wheels) on the Panamera is 2.1 inches wider in the front and 3.9 inches wider in the rear than the track on the AMG C 63 Sedan.

The Panamera Turbo handles at 1.00 G’s, while the AMG C 63 S Sedan pulls only .97 G’s of cornering force in a Car and Driver skidpad test.

Chassis

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 C 63 Sedan 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 C 63 Sedan doesn’t offer active noise cancellation.

Ergonomics

The Panamera’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The AMG C 63 Sedan does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the Panamera offers an optional rear wiper. The AMG C 63 Sedan doesn’t offer a rear wiper.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Panamera offers available headlight washers to keep headlight output high. The AMG C 63 Sedan doesn’t offer headlight washers.

Both the Panamera and the AMG C 63 Sedan have standard heated front seats. The Panamera also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the AMG C 63 Sedan.

Optional air conditioned front and rear seats keep the Panamera’s passengers comfortable and take the sting out of hot leather in summer. The AMG C 63 Sedan doesn’t offer air-conditioned seats in the rear.
