Safety

The Panamera offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The S7 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 S7 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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, night vision systems, lane departure warning systems and blind spot warning systems.

Fuel Economy and Range

On the EPA test cycle the Panamera Turbo S E-Hybrid Running on electricity gets better fuel mileage than the S7 SMG (48 city/51 hwy vs. 16 city/24 hwy).

The Panamera 4 E-Hybrid can drive on battery power alone for up to 31 miles. The S7 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 S7 doesn’t offer a regenerative braking system.

The Panamera E Hybrid’s standard fuel tank has 1.3 gallons more fuel capacity than the S7 (21.1 vs. 19.8 gallons), for longer range between fill-ups. The Panamera’s standard fuel tank has 3.9 gallons more fuel capacity than the S7 (23.7 vs. 19.8 gallons).

Transmission

An eight-speed automatic (SMG) is standard on the Porsche Panamera, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the S7.

Brakes and Stopping

For better stopping power the Panamera’s front brake rotors are larger than those on the S7:

Rear Rotors

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 S7 doesn’t offer ceramic brake rotors.

The Panamera stops shorter than the S7:

Tires and Wheels

For better traction and acceleration, the Panamera has larger standard rear tires than the S7 (295/40R19 vs. 265/35R20). The Panamera’s optional rear tires are larger than the largest rear tires available on the S7 (315/35R20 vs. 275/30R21).

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 S7 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. Audi doesn’t offer an active suspension on the S7.

For a smoother ride and more stable handling, the Panamera’s wheelbase is 1.3 inches longer than on the S7 (116.1 inches vs. 114.8 inches). The Panamera Executive’s wheelbase is 7.2 inches longer than on the S7 (122 inches vs. 114.8 inches).

The Panamera’s front to rear weight distribution is more even (51.2% to 48.8%) than the S7’s (55.8% to 44.2%). This gives the Panamera more stable handling and braking.

The Panamera 4S handles at 1.01 G’s, while the S7 pulls only .94 G’s of cornering force in a Motor Trend skidpad test.

The Panamera Turbo executes Motor Trend’s “Figure Eight” maneuver quicker than the S7 (23.9 seconds @ .86 average G’s vs. 24.8 seconds @ .81 average G’s).

Chassis

The Porsche Panamera may be more efficient, handle and accelerate better because it weighs up to about 500 pounds less than the Audi S7.

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 S7 doesn’t offer active grille shutters.

As tested by Car and Driver while under full throttle, the interior of the Panamera Turbo is quieter than the S7 (75 vs. 77 dB).

Passenger Space

The Panamera has 14 cubic feet more passenger volume than the S7 (108 vs. 94).

For enhanced passenger comfort on long trips the Panamera’s available rear seats recline. The S7’s rear seats don’t recline.

Cargo Capacity

Pressing a switch automatically lowers the Panamera’s rear seats, to make changing between passengers and cargo easier. The S7 doesn’t offer automatic folding seats.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Porsche service is better than Audi. J.D. Power ranks Porsche second in service department satisfaction. With a 3% lower rating, Audi is ranked third.

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 S7 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 S7 doesn’t offer a rear wiper.

A power rear sunshade is optional in the Panamera to help block heat and glare for the rear passengers. The S7 doesn’t offer a rear sunshade.

Optional air conditioned front and rear seats keep the Panamera’s passengers comfortable and take the sting out of hot leather in summer. The S7 doesn’t offer air-conditioned seats in the rear.

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 S7 doesn’t offer a house-current electrical outlet.

Model Availability

The Porsche Panamera comes in four door hatchback and station wagon bodystyles; the Audi S7 isn’t available as a station wagon.

The Panamera is available in both rear-wheel drive and all-wheel drive configurations. The S7 doesn’t offer a two-wheel drive configuration.

Recommendations

The Porsche Panamera outsold the Audi A7/S7/RS 7 by over two to one during 2018.
