The Panamera offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The C63 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the Panamera and the C63 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The Panamera’s corrosion warranty is 6 years and unlimited miles longer than the C63’s (10/unlimited vs. 4/50,000).

Reliability Comparison

J.D. Power and Associates rated the Panamera third among large premium cars in their 2013 Initial Quality Study. The C63 isn’t in the top three in its category.

J.D. Power and Associates’ 2013 Initial Quality Study of new car owners surveyed provide the statistics that show that Porsche vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Porsche first in initial quality, above the industry average. With 26 more problems per 100 vehicles, Mercedes is ranked 11th.

The Panamera S E-Hybrid can drive on battery power alone for up to 22 miles. The C63 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 C63 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Panamera’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The C63 doesn’t offer an automatic engine start/stop system.

The Panamera Hybrid/V6/S RWD’s standard fuel tank has 3.7 gallons more fuel capacity than the C63 (21.1 vs. 17.4 gallons), for longer range between fill-ups. The Panamera S4/GTS/Turbo’s standard fuel tank has 9 gallons more fuel capacity than the C63 (26.4 vs. 17.4 gallons).

Brakes and Stopping Comparison

For better stopping power the Panamera Turbo/GTS’ brake rotors are larger than those on the C63:

16.1 inches

14.2 inches

Rear Rotors

13.8 inches

13 inches

The Panamera’s brakes have 33% more swept area (the area covered by the brake pads) than the C63 (836 vs. 629 square inches), so the Panamera has more braking power available.

The Panamera offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The C63 doesn’t offer ceramic brake rotors.

The Panamera stops shorter than the C63:

Tires and Wheels Comparison

For better traction, the Panamera has larger standard tires than the C63 (F:245/50R18 & R:275/45R18 vs. F:235/40R18 & R:255/35R18). The Panamera’s optional tires are larger than the largest tires available on the C63 (F:255/40R20 & R:295/35R20 vs. F:235/40R18 & R:255/35R18).

For better ride, handling and brake cooling the Panamera offers optional 20-inch wheels. The C63’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 C63.

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 C63 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Panamera’s wheelbase is 6.3 inches longer than on the C63 (115 inches vs. 108.7 inches).

For better handling and stability, the average track (width between the wheels) on the Panamera is 3.5 inches wider in the front and 5.3 inches wider in the rear than the track on the C63.

The Panamera Turbo 4 handles at .97 G’s, while the C63 Sedan pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

The Panamera goes through Road & Track’s slalom 1.9 MPH faster than the C63 Sedan (71.2 vs. 69.3 MPH).

The Panamera Turbo 4 performs Car and Driver’s emergency lane change maneuver 4 MPH faster than the C63 Sedan (68 vs. 64 MPH).

The Panamera Turbo 4 executes Motor Trend’s “Figure Eight” maneuver quicker than the C63 Sedan (24.4 seconds @ .81 average G’s vs. 24.9 seconds @ .78 average G’s).

Passenger Space Comparison

Because it has more passenger and cargo room, the Panamera is rated a Mid-size car by the EPA, while the C63 Sedan is rated a Compact.

The Panamera has 9.8 cubic feet more passenger volume than the C63 (98 vs. 88.2).

The Panamera has .9 inches more front headroom, .2 inches more front legroom and 1.3 inches more rear headroom than the C63 Sedan.

For enhanced passenger comfort on long trips the Panamera’s available rear seats recline. The C63’s rear seats don’t recline.

Cargo Capacity Comparison

The Panamera has a much larger trunk with its rear seat up than the C63 Sedan (15.7 vs. 12.4 cubic feet).

To make loading and unloading groceries and cargo easier, especially for short adults or children, the Panamera has a standard power rear liftgate, which opens and closes automatically by pressing a button. The C63 doesn’t offer a power trunk.

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 C63 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 C63 does not have an oil pressure gauge.

The Panamera’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The C63’s standard manually variable intermittent wipers have to be constantly adjusted.

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 C63 doesn’t offer heated windshield washer nozzles.

To improve rear visibility by keeping the rear window clear, the Panamera offers an optional rear wiper. The C63 doesn’t offer a rear wiper.

Both the Panamera and the C63 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 C63.

The Panamera’s optional air conditioned front seats cool the driver and front passenger and help take the sting out of hot leather in Summer. The C63 doesn’t offer air conditioned front seats.

To help keep rear passengers entertained, the Panamera offers optional rear seat controls for the radio which can play a separate audio source. The C63 doesn’t offer rear seat audio controls.

The Panamera offers an optional 115 volt a/c outlet in the center console, allowing you to recharge a laptop or run small household appliances without special adapters which can break or get misplaced. The C63 doesn’t offer a house-current electrical outlet.

Economic Advantages Comparison

The Panamera will cost the buyer less in the long run because of its superior resale value. Kiplinger’s estimates that the Panamera will retain 39% to 40% of its original price after five years, while the C63 only retains 36% to 37%.

Recommendations Comparison

Both the Porsche Panamera and Mercedes C63 won an award in Kiplinger’s 2013 car issue.
