The A7’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The QX50 doesn’t offer pre-crash pretensioners.

Both the A7 and QX50 have child safety locks to prevent children from opening the rear doors. The A7 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 QX50’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 A7 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 QX50 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 A7. But it costs extra on the QX50.

A passive infrared night vision system optional on the A7 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 QX50 doesn’t offer a night vision system.

Both the A7 and the QX50 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, 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 blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, its standard front crash prevention system, its “Good” rating in the new passenger-side small overlap crash test, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the A7 the rating of “Top Pick” for 2019, a rating granted to only 106 vehicles tested by the IIHS. The QX50 has not been tested, yet.

The A7’s corrosion warranty is 5 years longer than the QX50’s (12 vs. 7 years).

There are over 42 percent more Audi dealers than there are Infiniti dealers, which makes it easier should you ever need service under the A7’s warranty.

J.D. Power and Associates rated the A7 third among midsize premium cars in their 2019 Initial Quality Study. The QX50 isn’t in the top three in its category.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Infiniti vehicles. J.D. Power ranks Audi 8th in reliability, above the industry average. With 4 more problems per 100 vehicles, Infiniti is ranked 11th.

On the EPA test cycle the A7 SMG gets better fuel mileage than the QX50 AWD CVT (22 city/29 hwy vs. 22 city/28 hwy).

On the EPA test cycle the A7 Auto gets better fuel mileage than the QX50 AWD CVT (22 city/29 hwy vs. 22 city/28 hwy).

Regenerative brakes improve the A7’s fuel efficiency by converting inertia back into energy instead of wasting it. The QX50 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the A7’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The QX50 doesn’t offer an automatic engine start/stop system.

The A7 has 3.3 gallons more fuel capacity than the QX50 (19.3 vs. 16 gallons), for longer range between fill-ups.

The A7 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The QX50 doesn’t offer a cap-less fueling system.

For better traction, the A7 has larger standard tires than the QX50 (245/45R19 vs. 235/55R19).

The A7’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 QX50’s standard 55 series tires. The A7 Prestige’s optional tires have a lower 35 series profile than the QX50 Sensory/Autograph’s 45 series tires.

For better ride, handling and brake cooling the A7 Prestige offers optional 21-inch wheels. The QX50’s largest wheels are only 20-inches.

The A7 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 QX50; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling

The A7 offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The QX50’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the A7’s wheelbase is 5 inches longer than on the QX50 (115.2 inches vs. 110.2 inches).

The A7’s front to rear weight distribution is more even (53.9% to 46.1%) than the QX50’s (57.9% to 42.1%). This gives the A7 more stable handling and braking.

The A7 Prestige handles at .86 G’s, while the QX50 Essential AWD pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The A7 is 10 inches shorter in height than the QX50, making the A7 much easier to wash and garage and drive (lower center of gravity).

The design of the Audi A7 amounts to more than styling. The A7 has an aerodynamic coefficient of drag of .28 Cd. That is significantly lower than the QX50 (.32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the A7 get better fuel mileage.

The engine in the A7 is mounted longitudinally (North-South), instead of sideways, as in the QX50. This makes it easier to service and maintain, because the accessory belts are in front.

The A7’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the QX50, and is not available on all models.

The power windows standard on both the A7 and the QX50 have locks to prevent small children from operating them. When the lock on the A7 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX50 prevents the driver from operating the other windows just as it does the other passengers.

If the windows are left open on the A7 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 QX50 can only close the windows from inside the vehicle, with the ignition on.

The A7’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 QX50’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A7 Premium Plus/Prestige has standard headlight washers to keep headlight output high. The QX50 doesn’t offer headlight washers.

A power rear sunshade is optional in the A7 to help block heat and glare for the rear passengers. The QX50 doesn’t offer a rear sunshade.

The A7’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Infiniti only offers heated mirrors on the QX50 Essential/Sensory/Autograph.

The A7 has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The QX50 offers an automatic rear view mirror, but its side mirrors don’t dim.

The A7 has standard heated front seats. Heated front seats cost extra on the QX50, and aren’t available on the QX50 Pure. The A7 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX50.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi A7 offers an optional wireless phone charging system (Qi) in the center console. The QX50 doesn’t offer wireless personal charging.

J.D. Power and Associates rated the A7 first among midsize premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The QX50 isn’t in the top three.
