The S7’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 S7 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 S7 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 S7 Prestige 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. The Model S doesn’t offer a night vision system.

The S7 offers an optional Top and Corner View Cameras 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 S7’s optional Rear Cross-Traffic Assist uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Model S doesn’t offer a rear cross-path warning system.

The S7 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 S7 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.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Audi S7 is safer than the Tesla Model S:

	S7	Model S
	Front Seat
STARS	5 Stars	5 Stars
HIC	135	160
Hip Force	262 lbs.	339 lbs.
	Rear Seat
STARS	5 Stars	5 Stars
HIC	135	197
Spine Acceleration	43 G’s	47 G’s
	Into Pole
STARS	5 Stars	5 Stars
HIC	395	449
Spine Acceleration	39 G’s	46 G’s
Hip Force	514 lbs.	785 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Warranty

There are over 58 percent more Audi dealers than there are Tesla dealers, which makes it much easier should you ever need service under the S7’s warranty.

Reliability

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.

Brakes and Stopping

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

	S7	Model S
Front Rotors	15.8 inches	15 inches

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The S7 has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Model S doesn’t offer a brake assist feature.

Tires and Wheels

The S7’s tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Model S’ standard 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the S7 has standard 21-inch wheels. Smaller 19-inch wheels are standard on the Model S.

The S7 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.

Passenger Space

The S7 has 1.5 inches more rear legroom and .8 inches more rear shoulder room than the Model S.

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

Cargo Capacity

To make loading groceries and cargo easier when your hands are full, the S7’s liftgate 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 S7 to save the owner time and money by calculating maintenance intervals 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 S7’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 S7 Premium Plus/Prestige offers an optional 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 S7 Prestige has a standard heads-up display that projects speed, warning and navigation instruction 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.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The S7 has standard headlight washers to keep headlight output high. The Model S doesn’t offer headlight washers.

The S7’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 S7 has standard extendable sun visors. The Model S doesn’t offer extendable visors.

Manual rear side window sunshades are available in the S7 to help block heat and glare for the rear passengers. The Model S doesn’t offer rear side window sunshades.

The S7 Premium Plus/Prestige offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Model S.
