The A8’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Model S doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Audi A8 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 Tesla Model S doesn’t offer height-adjustable seat belts.

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 Model S 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 Model S 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.

A passive infrared night vision system optional on the A8 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard and even aims one of the vehicle’s headlights in the direction of the person or object. The Model S doesn’t offer a night vision system.

The A8 has a standard Top View Camera System to allow the driver to see objects all around the vehicle on a screen. The Model S 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.

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 Model S doesn’t offer a rear cross-path warning system.

The A8 has standard Audi Connect Care, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model S doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

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

Warranty

There are almost 2 times as many Audi dealers as there are Tesla dealers, which makes it much easier should you ever need service under the A8’s warranty.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the A8’s reliability 25 points higher than the Model S.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Audi vehicles are better in initial quality than Tesla vehicles. With 36 fewer problems per 100 vehicles, JD Power ranks Audi higher than Tesla.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Audi vehicles are more reliable than Tesla vehicles. Consumer Reports ranks Audi 13 places higher in reliability than Tesla.

Brakes and Stopping

The A8 stops shorter than the Model S:

	A8	Model S
70 to 0 MPH	149 feet	150 feet	Car and Driver

Tires and Wheels

The A8 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Model S; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

The A8 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Tesla doesn’t offer an active suspension on the Model S.

For a smoother ride and more stable handling, the A8’s wheelbase is 6.7 inches longer than on the Model S (123.2 inches vs. 116.5 inches).

The A8 55 TFSI handles at .93 G’s, while the Model S pulls only .86 G’s of cornering force in a Car and Driver skidpad test.

The A8 55 TFSI executes Motor Trend’s “Figure Eight” maneuver quicker than the Model S (25.9 seconds @ .7 average G’s vs. 26.5 seconds @ .7 average G’s).

Passenger Space

The A8 has 17 cubic feet more passenger volume than the Model S (111 vs. 94).

The A8 has .7 inches more front shoulder room, .4 inches more rear headroom, 8.8 inches more rear legroom and 2.5 inches more rear shoulder room than the Model S.

For enhanced passenger comfort on long trips the A8’s available rear seats recline. The Model S’ rear seats don’t recline.

Cargo Capacity

With its sedan body style, valet key and remote trunk release lockout, the A8 offers cargo security. The Model S’ hatchback body style and non-lockable folding seat defeat cargo security.

To make loading groceries and cargo easier when your hands are full, the A8’s trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Model S doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Servicing Ease

A Service Interval Display is standard on the A8 to save the owner time and money by calculating maintenance intervals for oil changes and vehicle inspections based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Tesla doesn’t offer a maintenance reminder on the Model S.

Ergonomics

The A8’s entire steering wheel hub sounds the horn, facilitating hitting the horn in an emergency. The Model S has a small, single button on the steering wheel spoke that can be hard to find quickly in an emergency.

Unlike the driver-only memory system in the Model S, the A8 has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle and climate settings and the front passenger seat also adjusts to the new passenger’s preset preferences.

The A8 offers an optional heads-up display that projects speed, warning, navigation instruction and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Model S doesn’t offer a heads-up display.

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 Model 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 Model S doesn’t offer heated windshield washer fluid. Its standard heated washer nozzles will defrost the washer fluid but not the windshield.

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 Model S doesn’t offer headlight washers.

The A8’s standard side window demisters help clear frost or condensation from the side windows in the winter. The Model S doesn’t even offer side window demisters, so the driver may have to wipe the windows from the outside to gain side vision.

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 Model S doesn’t offer extendable visors.

A power rear sunshade and rear side window sunshades are standard in the A8 to help block heat and glare for the rear passengers. The Model S doesn’t offer a rear or rear side window sunshades.

The A8 has standard front air conditioned seats and offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The Model S doesn’t offer air-conditioned seats in the rear.

The A8 offers optional massaging front and rear seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Model S.

The A8 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 Model S doesn’t offer a house-current electrical outlet.
