Safety

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. The Infiniti Q50 doesn’t offer pretensioners for the rear seat belts.

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.

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 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, crash mitigating brakes, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The A7’s corrosion warranty is 5 years longer than the Q50’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.

Engine

The A7’s 3.0 turbo V6 hybrid produces 127 more horsepower (335 vs. 208) and 111 lbs.-ft. more torque (369 vs. 258) than the Q50 2.0t’s standard 2.0 turbo 4 cyl. The A7’s 3.0 turbo V6 hybrid produces 35 more horsepower (335 vs. 300) and 74 lbs.-ft. more torque (369 vs. 295) than the Q50 3.0t’s standard 3.0 turbo V6. The A7’s 3.0 turbo V6 hybrid produces 19 lbs.-ft. more torque (369 vs. 350) than the Q50 Red Sport 400’s standard 3.0 turbo V6.

Fuel Economy and Range

On the EPA test cycle the A7 gets better fuel mileage than the Q50 3.0t AWD (22 city/29 hwy vs. 19 city/27 hwy). The A7 gets better fuel mileage than the Q50 2.0t AWD (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 Q50 doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Audi A7 uses regular unleaded gasoline (premium recommended for maximum performance). The Q50 requires premium, which can cost 20 to 55 cents more per gallon.

Transmission

The A7 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Q50 doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

For better stopping power the A7’s standard brake rotors are larger than those on the Q50:

Rear Rotors

Tires and Wheels

For better traction, the A7 has larger standard tires than the Q50 (245/45R19 vs. 225/55R17). The A7’s optional tires are larger than the largest tires available on the Q50 (255/40R20 vs. 245/40R19).

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 Q50’s standard 55 series tires. The A7 Prestige’s optional tires have a lower 35 series profile than the Q50 Red Sport 400’s 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 Prestige’s optional 21-inch wheels are larger than the 19-inch wheels on the Q50 Sport/Red Sport 400 AWD.

Suspension and Handling

For a smoother ride and more stable handling, the A7’s wheelbase is 3 inches longer than on the Q50 (115.2 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the A7 is 4.5 inches wider in the front and 3 inches wider in the rear than the average track on the Q50.

For better maneuverability, the A7’s turning circle is .3 feet tighter than the Q50’s (36.4 feet vs. 36.7 feet). The A7’s turning circle is 1 foot tighter than the Q50 AWD’s (36.4 feet vs. 37.4 feet).

Passenger Space

The A7 has .5 inches more front shoulder room and 1.9 inches more rear legroom than the Q50.

Cargo Capacity

The A7 has a much larger trunk than the Q50 3.0t/Red Sport 400 (24.9 vs. 13.5 cubic feet). The A7 has a much larger trunk than the Q50 2.0t (24.9 vs. 13.2 cubic feet).

The A7’s standard rear seats fold to accommodate long and bulky cargo. The Q50 Pure doesn’t offer folding rear seats.

To make loading and unloading groceries and cargo easier when your hands are full, just kicking your foot under the back bumper can open the A7’s power liftgate, leaving your hands completely free. The A7’s power liftgate can also be opened or closed by pressing a button. The Q50 doesn’t offer a power or hands-free opening trunk.

Ergonomics

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.

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 offers available headlight washers to keep headlight output high. The Q50 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 Q50 doesn’t offer a rear sunshade.

The A7 has standard heated front seats. Heated front seats cost extra on the Q50, and aren’t available on the Q50 2.0t. 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.

Optional air-conditioned seats in the A7 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.
