Safety

Both the Panamera and AMG E 63 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 E 63’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 E 63 doesn’t offer a whiplash protection system.

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 E 63 doesn’t offer a night vision system.

The Panamera’s optional 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. The AMG E 63 doesn’t offer a lane departure warning system.

Both the Panamera and the AMG E 63 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, blind spot warning systems and around view monitors.

Fuel Economy and Range

On the EPA test cycle the Panamera Turbo S E-Hybrid Running on electricity gets better fuel mileage than the AMG E 63 (48 city/51 hwy vs. 16 city/22 hwy).

On the EPA test cycle the Panamera Turbo 4 Auto 4.0 twin turbo V8 (550 HP) gets better fuel mileage than the AMG E 63 S Sedan (18 city/23 hwy vs. 15 city/22 hwy).

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

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

The Panamera’s standard fuel tank has 2.6 gallons more fuel capacity than the AMG E 63 (23.7 vs. 21.1 gallons).

Transmission

Tires and Wheels

For better traction, the Panamera’s optional tires are larger than the largest tires available on the AMG E 63 (F:275/40R20 & R:315/35R20 vs. F:265/35R20 & R:295/30R20).

For better ride, handling and brake cooling the Panamera offers optional 21-inch wheels. The AMG E 63’s largest wheels are only 20-inches.

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 E 63 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 E 63.

For a smoother ride and more stable handling, the Panamera’s wheelbase is .4 inches longer than on the AMG E 63 Sedan (116.1 inches vs. 115.7 inches). The Panamera Executive’s wheelbase is 6.3 inches longer than on the AMG E 63 Sedan (122 feet vs. 115.7 inches).

For better handling and stability, the average track (width between the wheels) on the Panamera is .6 inches wider in the front and 2 inches wider in the rear than the track on the AMG E 63.

The Panamera’s front to rear weight distribution is more even (51.2% to 48.8%) than the AMG E 63’s (55.3% to 44.7%). This gives the Panamera more stable handling and braking.

For better maneuverability, the Panamera’s turning circle is 2.3 feet tighter than the AMG E 63 Sedan’s (39 feet vs. 41.3 feet).

Chassis

The Porsche Panamera may be more efficient, handle and accelerate better because it weighs up to about 500 pounds less than the Mercedes AMG E 63.

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 E 63 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 E 63 doesn’t offer active noise cancellation.

As tested by Car and Driver, the interior of the Panamera Turbo is quieter than the AMG E 63 S Sedan:

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Panamera 4dr Hatchback a Large car, while the AMG E 63 Sedan is rated a Mid-size. The EPA rates the Panamera Sport Turismo a Large car, while the AMG E 63 Wagon is rated a Mid-Size Station Wagon.

The Panamera has 10 cubic feet more passenger volume than the AMG E 63 (108 vs. 98).

For enhanced passenger comfort on long trips the Panamera’s available rear seats recline. The AMG E 63’s middle row seats don’t recline.

Cargo Capacity

The Panamera Sport Turismo has a much larger trunk with its rear seat folded than the AMG E 63 Wagon with its rear seat folded (49 vs. 35 cubic feet).

Pressing a switch automatically lowers the Panamera’s rear seats, to make changing between passengers and cargo easier. The AMG E 63 doesn’t offer automatic folding seats.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Porsche service is better than Mercedes. J.D. Power ranks Porsche second in service department satisfaction. With a 6% lower rating, Mercedes is ranked 6th.

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 E 63 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 E 63 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 E 63 doesn’t offer headlight washers.

On extremely cold winter days, the Panamera’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The AMG E 63 doesn’t offer a heated steering wheel.

Model Availability

The Panamera is available in both rear-wheel drive and all-wheel drive configurations. The AMG E 63 doesn’t offer a two-wheel drive configuration.
