Compare the2024 Audi A8VS 2024 Porsche Taycan

The A8 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Taycan doesn’t offer front seat center airbags.

The A8 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Taycan doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A8. But it costs extra on the Taycan.

To help make backing out of a parking space safer, the A8’s optional Rear Cross-Traffic Assist uses sensors in the rear to alert the driver to vehicles approaching from the side and Automatic Brake Activation automatically engages the brakes to help avoid a collision. The Taycan doesn’t offer a rear cross-path warning system.

Both the A8 and the Taycan have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available night vision systems and blind spot warning systems.

For better stopping power the A8’s standard front brake rotors are larger than those on the Taycan:

The A8 stops much shorter than the Taycan:

For better traction, the A8 has larger standard tires than the Taycan (255/45R19 vs. 225/55R19).

The A8’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Taycan’s standard 55 series front tires.

The A8 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The A8’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 Taycan doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the A8’s wheelbase is 9 inches longer than on the Taycan (123.2 inches vs. 114.2 inches).

The A8 55 TFSI handles at .93 G’s, while the Taycan pulls only .89 G’s of cornering force in a Car and Driver skidpad test.

If the windows are left open on the A8 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Taycan can only operate the windows from inside the vehicle, with the ignition on.

The A8’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Taycan’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Heated windshield washer fluid is optional on the A8 to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The Taycan doesn’t offer heated windshield washer fluid.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A8 has standard headlight washers to keep headlight output high. The Taycan doesn’t offer headlight washers.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the A8 has standard extendable sun visors. The Taycan doesn’t offer extendable visors.
