Tires and Wheels Comparison

For better ride, handling and brake cooling the Panamera offers optional 20-inch wheels. The E63’s largest wheels are only 19-inches.

Suspension and Handling Comparison

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 E63.

For a smoother ride and more stable handling, the Panamera’s wheelbase is 1.8 inches longer than on the E63 Sedan (115 inches vs. 113.2 inches).

For better handling and stability, the average track (width between the wheels) on the Panamera is 1.2 inches wider in the front and 2.1 inches wider in the rear than the track on the E63.

The Panamera Turbo S 4 handles at .99 G’s, while the E63 AMG S-Model Sedan pulls only .89 G’s of cornering force in a Road & Track skidpad test.

The Panamera Turbo 4 executes Motor Trend’s “Figure Eight” maneuver quicker than the E63 AMG S-Model Sedan (23.7 seconds @ .87 average G’s vs. 24.3 seconds @ .83 average G’s).

Chassis Comparison

The Porsche Panamera may be more efficient, handle and accelerate better because it weighs about 50 to 500 pounds less than the Mercedes E63.

Passenger Space Comparison

The Panamera has .1 inches more front headroom and .6 inches more front legroom than the E63 Sedan.

For enhanced passenger comfort on long trips the Panamera’s available rear seats recline. The E63’s middle row seats don’t recline.

Cargo Capacity Comparison

To allow full utilization of available cargo room, the Panamera’s hatch uses gas strut supported hinges that don’t intrude into the cargo area. The E63’s useful trunk space is reduced by its intrusive beam hinge.

Ergonomics Comparison

The Panamera offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The E63 doesn’t offer a remote starting system.

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 E63 does not have an oil pressure gauge.

Heated windshield washer nozzles are standard on the Panamera to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The E63 doesn’t offer heated windshield washer nozzles.

To improve rear visibility by keeping the rear window clear, the Panamera offers an optional rear fixed intermittent wiper with a full on position. The rear wiper standard on the E63 only has an intermittent setting, so in a hard rain visibility isn’t as good.

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 has standard headlight washers to keep headlight output high. The E63 doesn’t offer headlight washers.

Both the Panamera and the E63 have standard heated front seats. The Panamera also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the E63.
