J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Porsche vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Porsche above average in initial quality. With 54 more problems per 100 vehicles, Audi is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Porsche vehicles are more reliable than Audi vehicles. J.D. Power ranks Porsche above average in long-term dependability. With 30 more problems per 100 vehicles in the first three years of ownership, Audi is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Porsche vehicles are more reliable than Audi vehicles. Consumer Reports ranks Porsche 11 places higher in reliability than Audi.

The Taycan’s standard electric motor produces 67 more horsepower (402 vs. 335) than the A8’s 3.0 turbo V6 hybrid. The Taycan Performance Plus’ optional electric motor produces 134 more horsepower (469 vs. 335) than the A8’s 3.0 turbo V6 hybrid. The Taycan Cross Turismo’s standard electric motors produces 134 more horsepower (469 vs. 335) than the A8’s 3.0 turbo V6 hybrid. The Taycan 4S’ standard electric motors produces 187 more horsepower (522 vs. 335) and 103 lbs.-ft. more torque (472 vs. 369) than the A8’s 3.0 turbo V6 hybrid. The Taycan Turbo S’ standard electric motors produces 415 more horsepower (750 vs. 335) and 405 lbs.-ft. more torque (774 vs. 369) than the A8’s 3.0 turbo V6 hybrid.

As tested in Motor Trend the Porsche Taycan is faster than the Audi A8:

On the EPA test cycle the Taycan Sedan gets better mileage than the A8:

The Taycan can travel with zero emissions for 206 to 246 miles (dependent on model). The A8 can’t move without running its internal combustion engine.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Porsche Taycan higher (10 out of 10) than the Audi A8 (5). This means the Taycan produces up to 19.8 pounds less smog-producing pollutants than the A8 every 15,000 miles.

The Taycan’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The A8 doesn’t offer launch control.

For better stopping power the Taycan Turbo S’ brake rotors are larger than those on the A8:

The Taycan 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 A8 doesn’t offer ceramic brake rotors.

The Taycan stops shorter than the A8:

For better traction and acceleration, the Taycan has larger standard rear tires than the A8 (275/45R19 vs. 255/45R19). The Taycan’s optional rear tires are larger than the largest rear tires available on the A8 (305/30R21 vs. 265/40R20).

The Taycan’s optional 305/30R21 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the A8’s optional 35 series tires.

The Taycan 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 A8 doesn’t offer an active sway bar system.

For better handling and stability, the average track (width between the wheels) on the Taycan is 2.4 inches wider in the front and 1.8 inches wider in the rear than the track on the A8.

The Taycan 4S handles at 1.03 G’s, while the A8 55 TFSI pulls only .89 G’s of cornering force in a Motor Trend skidpad test.

The Taycan Turbo S executes Motor Trend’s “Figure Eight” maneuver 2.3 seconds quicker than the A8 55 TFSI (23.6 seconds @ .87 average G’s vs. 25.9 seconds @ .7 average G’s).

For better maneuverability, the Taycan w/Rear Axle Steering’s turning circle is 5.5 feet tighter than the A8’s (36.7 feet vs. 42.2 feet). The Taycan Cross Turismo’s turning circle is 2.8 feet tighter than the A8’s (39.4 feet vs. 42.2 feet).

The Taycan is 1 foot, 1.3 inches shorter than the A8, making the Taycan easier to handle, maneuver and park in tight spaces.

The front grille of the Taycan uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The A8 doesn’t offer active grille shutters.

The Taycan has a much larger trunk than the A8 (17.2 vs. 12.5 cubic feet).

The Taycan has a much larger trunk with its rear seat up than the A8 (18.7 vs. 12.5 cubic feet).

The Taycan’s available rear seats fold to accommodate long and bulky cargo. The A8 doesn’t offer folding rear seats, only a ski pass-through.

J.D. Power and Associates surveys of service recipients show that Porsche service is better than Audi. J.D. Power ranks Porsche third in service department satisfaction. With a 14% lower rating, Audi is ranked 8th.

The A8’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The Taycan’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

The Porsche Taycan comes in sedan and station wagon bodystyles; the Audi A8 isn’t available as a station wagon.

The Taycan is available in both rear-wheel drive and all-wheel drive configurations. The A8 doesn’t offer a two-wheel drive configuration.

J.D. Power and Associates rated the Taycan first among upper midsize premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The A8 isn’t in the top three.

The Porsche Taycan outsold the Audi A8/S8 by over three to one during 2023.
