Safety

For enhanced safety, the front and rear seat shoulder belts of the Audi Q8 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Tesla Model X doesn’t offer pretensioners for the rear seat belts.

The Q8’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Model X doesn’t offer pre-crash pretensioners.

The Q8 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 X 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.

When descending a steep, off-road slope, the Q8’s standard Hill Descent Assist allows you to creep down safely. The Model X doesn’t offer Hill Descent Assist.

A passive infrared night vision system optional on the Q8 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 X doesn’t offer a night vision system.

The Q8’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Model X doesn’t offer a lane departure warning system.

The Q8 Premium Plus/Prestige has a standard Top View Cameras to allow the driver to see objects all around the vehicle on a screen. The Model X 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 safer, the Q8’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Model X doesn’t offer a cross-path warning system.

The Q8 has a standard Audi Connect CARE, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model X 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 Q8 and the Model X have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, rearview cameras and available blind spot warning systems.

Warranty

The Q8’s corrosion warranty is 8 years and unlimited miles longer than the Model X’s (12/unlimited vs. 4/50,000).

There are almost 5 times as many Audi dealers as there are Tesla dealers, which makes it much easier should you ever need service under the Q8’s warranty.

Reliability

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Tesla vehicles. Consumer Reports ranks Audi 20 places higher in reliability than Tesla.

Engine

The Q8’s 3.0 turbo V6 hybrid produces 7 more horsepower (335 vs. 328) than the Model X 75D’s standard electric motor.

Fuel Economy and Range

The Q8’s maximum EPA estimated driving range on a full tank of fuel is 495 miles, after which it can be refueled at any gas station in minutes. The Model X’s range is only 237 to 295 miles, after which the minimum recharge time is 30 minutes for only a 54% charge at a specially configured quick charge station not available in most areas. A full recharge at a conventional charging station can take up to 82 hours and 53 minutes.

Brakes and Stopping

For better stopping power the Q8’s front brake rotors are larger than those on the Model X:

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The Q8 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 X doesn’t offer a brake assist feature.

Tires and Wheels

For better traction, the Q8 has larger standard tires than the Model X (275/50R20 vs. 255/45R20). The Q8’s optional tires are larger than the largest tires available on the Model X (285/45R21 vs. 265/35R22).

Suspension and Handling

For a smoother ride and more stable handling, the Q8’s wheelbase is 1.2 inches longer than on the Model X (117.9 inches vs. 116.7 inches).

Chassis

The Audi Q8 may be more efficient, handle and accelerate better because it weighs about 250 to 400 pounds less than the Tesla Model X.

Passenger Space

The Q8 has .5 inches more front legroom, 1.8 inches more rear legroom and 1.7 inches more rear shoulder room than the Model X.

Cargo Capacity

The Q8 has a much larger cargo area than the Model X with its rear seat up (28.6 vs. 26 cubic feet).

The Q8’s standard rear seats fold to accommodate long and bulky cargo. The Model X 6-Passenger doesn’t offer folding rear seats.

To make loading groceries and cargo easier when your hands are full, the Q8 Premium Plus/Prestige’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Model X doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Towing

The Q8’s standard towing capacity is much higher than the Model X’s (7700 vs. 5000 pounds).

While the Model X w/22” wheels can only tow 3500, any Q8 can tow a minimum of 7700 pounds.

Servicing Ease

A Service Interval Display is standard on the Q8 to save the owner time and money by calculating maintenance intervals for oil changes and vehicle inspection 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 X.

Ergonomics

Unlike the driver-only memory system in the Model X, the Q8 offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Q8’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The Model X doesn’t offer an easy entry system.

The Q8 Prestige has a standard heads-up display that projects speed readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Model X doesn’t offer a heads-up display.

If the windows are left open on the Q8 Premium Plus/Prestige 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 Model X can only operate the windows from inside the vehicle, with the ignition on.

To improve rear visibility by keeping the rear window clear, the Q8 has a standard rear wiper. The Model X doesn’t offer a rear wiper.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Q8 Prestige has standard headlight washers to keep headlight output high. The Model X doesn’t offer headlight washers.

The Q8’s standard side window demisters help clear frost or condensation from the side windows in the winter. The Model X 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 Q8 has standard extendable sun visors. The Model X doesn’t offer extendable visors.

A manual rear sunshade is optional in the Q8 to help block heat and glare for the rear passengers. The Model X doesn’t offer a rear sunshade.

Standard air-conditioned seats in the Q8 Premium Plus/Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Model X doesn’t offer air-conditioned seats.

The Q8 has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable. The Model X doesn’t offer a middle row seat center armrest.
