Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Porsche Panamera have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chevrolet SS doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Porsche Panamera are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Chevrolet SS doesn’t offer height-adjustable seat belts.

The Panamera offers optional Porsche Active Safe, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The SS has a collision warning system without the crash-mitigating brake feature which could reduce stopping distances.

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

The Panamera offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The SS 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 SS have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The Panamera comes with a full 4 year/50,000 mile basic warranty, which covers the entire car and includes 24 hour roadside assistance. The SS’ 3 year/36,000 mile basic warranty expires 1 year and 14,000 miles sooner.

The Panamera’s corrosion warranty is 4 years and unlimited miles longer than the SS’ (10/unlimited vs. 6/100,000).

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the Panamera has a standard 190-amp alternator. The SS’ 140-amp alternator isn’t as powerful.

J.D. Power and Associates rated the Panamera third among large premium cars in their 2013 Initial Quality Study. The SS 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 Chevrolet vehicles. J.D. Power ranks Porsche first in initial quality, above the industry average. With 17 more problems per 100 vehicles, Chevrolet is ranked fifth.

J.D. Power and Associates’ 2013 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Porsche vehicles are more reliable than Chevrolet vehicles. J.D. Power ranks Porsche second in reliability, above the industry average. With 31 more problems per 100 vehicles, Chevrolet is ranked 12th.

Engine Comparison

The Panamera S E-Hybrid’s standard 3.0 supercharged V6 hybrid produces 1 more horsepower (416 vs. 415) and 20 lbs.-ft. more torque (435 vs. 415) than the SS’ 6.2 V8. The Panamera S’ standard 3.0 turbo V6 produces 5 more horsepower (420 vs. 415) than the SS’ 6.2 V8. The Panamera GTS’ standard 4.8 DOHC V8 produces 25 more horsepower (440 vs. 415) than the SS’ 6.2 V8. The Panamera Turbo’s standard 4.8 turbo V8 produces 105 more horsepower (520 vs. 415) and 101 lbs.-ft. more torque (516 vs. 415) than the SS’ 6.2 V8.

The Panamera S E-Hybrid can drive on battery power alone for up to 22 miles. The SS 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 SS 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 SS doesn’t offer an automatic engine start/stop system.

The Panamera Hybrid/V6/S RWD’s standard fuel tank has 2.3 gallons more fuel capacity than the SS (21.1 vs. 18.8 gallons), for longer range between fill-ups. The Panamera S4/GTS/Turbo’s standard fuel tank has 7.6 gallons more fuel capacity than the SS (26.4 vs. 18.8 gallons).

Road & Track

Tires and Wheels Comparison

For better traction, the Panamera’s optional tires are larger than the largest tires available on the SS (F:255/40R20 & R:295/35R20 vs. F:245/40R19 & R:275/35R19).

For better ride, handling and brake cooling the Panamera offers optional 20-inch wheels. The SS’ 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. Chevrolet doesn’t offer an active suspension on the SS.

The Panamera offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The SS’ suspension doesn’t offer adjustable shock absorbers.

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 SS doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Panamera’s wheelbase is .2 inches longer than on the SS (115 inches vs. 114.8 inches). The Panamera Executive’s wheelbase is 6.1 inches longer than on the SS (120.9 feet vs. 114.8 inches).

For better handling and stability, the average track (width between the wheels) on the Panamera is 2.6 inches wider in the front and 1.9 inches wider in the rear than the track on the SS.

The Panamera Turbo 4 handles at 1.03 G’s, while the SS pulls only .92 G’s of cornering force in a Motor Trend skidpad test.

The Panamera Turbo 4 executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the SS (23.7 seconds @ .87 average G’s vs. 25.2 seconds @ .74 average G’s).

Passenger Space Comparison

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

Cargo Capacity Comparison

The Panamera’s standard rear seats fold to accommodate long and bulky cargo. The SS doesn’t offer folding rear seats, only a ski pass-through.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Panamera. The SS doesn’t offer locking storage for small valuables.

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 SS doesn’t offer a power trunk.

Ergonomics Comparison

Unlike the driver-only memory seat and mirrors in the SS, the Panamera offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position (with optional power wheel adjuster), outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Panamera’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The SS doesn’t offer an easy entry 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 SS does not have an oil pressure gauge.

The Panamera’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The SS’ rear power window switches have to be held the entire time to close them fully.

The Panamera has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The SS doesn’t offer a locking fuel door.

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

While driving with high beams on, sensitive light sensors available for the Panamera detect other vehicles which could be blinded and automatically switch to low beams. The SS doesn’t offer automatic dimming high beams.

To help drivers avoid possible obstacles, the Panamera offers optional cornering lights to illuminate around corners when the turn signals are activated. The SS doesn’t offer cornering lights. The Panamera also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

A power rear sunshade is optional in the Panamera to help block heat and glare for the rear passengers. The SS doesn’t offer a rear sunshade.

Both the Panamera and the SS 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 SS.

To keep a safe, consistent following distance, the Panamera offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The SS doesn’t offer an adaptive cruise control.

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

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

Recommendations Comparison

The Porsche Panamera outsold the Chevrolet SS by almost 13 to one during 2013.
