For enhanced safety, the front and rear seat shoulder belts of the Audi A7 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 Infiniti Q50 doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front and rear seat shoulder belts of the Audi A7 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 Infiniti Q50 has only front height-adjustable seat belts.

Both the A7 and Q50 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 Q50’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 Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. The Q50 doesn’t offer a whiplash protection system.

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 Q50 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 Q50.

An active 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 and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The Q50 doesn’t offer a night vision system.

Both the A7 and the Q50 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes and lane departure warning systems.

The A7’s corrosion warranty is 5 years longer than the Q50’s (12 vs. 7 years).

There are over 66 percent more Audi dealers than there are Infiniti dealers, which makes it much easier should you ever need service under the A7’s warranty.

The battery on the A7 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the A7’s battery 20 to 30 degrees cooler, its life is increased by years. The Q50’s battery is in the hot engine compartment.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without their vehicle while it’s being repaired. Consumer Reports predicts that the Audi A7 3.0T’s reliability will be 134% better than the Q50 and the Audi A7 3.0 TDI will be 139% better than the Q50.

J.D. Power and Associates’ 2015 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 14th in reliability, above the industry average. With 6 more problems per 100 vehicles, Infiniti is ranked 17th.

Regardless of its engine, the A7’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Infiniti only offers an automatic engine start/stop system on the Q50 Hybrid.

The A7 TDI’s standard fuel tank has 1.4 gallons more fuel capacity than the Q50 Hybrid’s standard fuel tank (19.2 vs. 17.8 gallons), for longer range between fill-ups.

For better traction, the A7 has larger standard tires than the Q50 (255/40R19 vs. 225/55R17). The A7’s optional tires are larger than the largest tires available on the Q50 (265/35R20 vs. 245/40R19).

The A7’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Q50’s standard 55 series tires. The A7’s optional tires have a lower 35 series profile than the Q50’s optional 40 series front tires.

For better ride, handling and brake cooling the A7 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Q50. The A7’s optional 20-inch wheels are larger than the 19-inch wheels on the Q50.

The A7 has standard front and rear gas-charged shocks for better control over choppy roads. The Q50’s suspension doesn’t offer gas-charged shocks.

For a smoother ride and more stable handling, the A7’s wheelbase is 2.5 inches longer than on the Q50 (114.7 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the A7 is 4.1 inches wider in the front and 2.8 inches wider in the rear than the average track on the Q50.

The A7 handles at .96 G’s, while the 3.7 Q50S pulls only .87 G’s of cornering force in a Motor Trend skidpad test.

The A7 executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the 3.7 Q50S (25.2 seconds @ .76 average G’s vs. 26.3 seconds @ .71 average G’s).

Unlike the driver-only memory system optional at extra cost in the Q50 Premium/Sport, the A7 Prestige 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 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 Q50, and is not available on all models.

The A7 Prestige has a standard heads-up display that projects speed 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 Q50 doesn’t offer a heads-up display.

The power windows standard on both the A7 and the Q50 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 Q50 prevents the driver from operating the other windows just as it does the other passengers.

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 Q50’s 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 A7 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Q50 doesn’t offer heated windshield washer nozzles.

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 Prestige has standard headlight washers to keep headlight output high. The Q50 doesn’t offer headlight washers.

The A7 has standard heated front seats. Heated front seats are only available on the Q50 Premium/Sport. 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 Q50.

Standard air conditioned seats in the A7 Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Q50 doesn’t offer air conditioned seats.
