Compare the2025 Audi Q4 e-tronVS 2025 Nissan Ariya

The Q4 e-tron’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Ariya doesn’t offer pre-crash pretensioners.

Both the Q4 e-tron and Ariya have child safety locks to prevent children from opening the rear doors. The Q4 e-tron has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Ariya’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Q4 e-tron 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 Ariya 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.

Both the Q4 e-tron and Ariya have rear cross-traffic warning, but the Q4 e-tron has Automatic Brake Activation (automatically applies the brakes) to better prevent a collision when backing near traffic. The Ariya’s Rear Cross Traffic Alert doesn’t automatically brake.

Both the Q4 e-tron and the Ariya have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front 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, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The Q4 e-tron’s standard 255/50R19 rear tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Ariya’s standard 55 series tires. The Q4 e-tron 55 e-tron’s optional 255/40R21 rear tires have a lower 40 series profile than the Ariya Platinum+’s optional 45 series tires.

For better ride, handling and brake cooling the Q4 e-tron 55 e-tron offers optional 21-inch wheels. The Ariya’s largest wheels are only 20-inches.

The Q4 e-tron’s standard towing capacity is much higher than the Ariya’s (2205 vs. 0 pounds). Maximum trailer towing in the Nissan Ariya e-4ORCE is only 1500 pounds. The Q4 e-tron offers up to a 2646 lbs. towing capacity.

The Q4 e-tron has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Ariya doesn’t offer a remote starting system.

If the windows are left open on the Q4 e-tron 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 Ariya can only close the windows from inside the vehicle, with the ignition on.

The Q4 e-tron’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Ariya’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer nozzles are standard on the Q4 e-tron to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Ariya doesn’t offer heated windshield washer nozzles.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Q4 e-tron’s headlights were rated “Good” to “Acceptable” by the IIHS, while the Ariya’s headlights are rated “Acceptable.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Q4 e-tron Prestige has standard headlight washers to keep headlight output high. The Ariya doesn’t offer headlight washers.

The Q4 e-tron’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Ariya offers an automatic rear view mirror, but its side mirrors don’t dim.
