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 Q70 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 Q70 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 Q70.

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 Q70 doesn’t offer a night vision system.

Both the A7 and the Q70 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, 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 Q70’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 5 more horsepower (335 vs. 330) and 99 lbs.-ft. more torque (369 vs. 270) than the Q70 3.7 LUXE’s standard 3.7 DOHC V6.

Fuel Economy and Range

On the EPA test cycle the A7 gets better fuel mileage than the Q70 3.7 AWD (22 city/29 hwy vs. 18 city/24 hwy). The A7 gets better fuel mileage than the Q70 5.6 AWD (22 city/29 hwy vs. 16 city/23 hwy).

Regenerative brakes improve the A7’s fuel efficiency by converting inertia back into energy instead of wasting it. The Q70 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 Q70 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Audi A7 uses regular unleaded gasoline (premium recommended for maximum performance). The Q70 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 Q70 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 Q70:

12.6 inches

Rear Rotors

Tires and Wheels

For better traction, the A7’s optional tires are larger than the largest tires available on the Q70 (255/40R20 vs. 245/40R20).

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 Q70’s standard 50 series tires. The A7 Prestige’s optional tires have a lower 35 series profile than the Q70’s optional 40 series tires.

For better ride, handling and brake cooling the A7 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Q70. The A7 Prestige’s optional 21-inch wheels are larger than the 20-inch wheels optional on the Q70.

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 Q70’s suspension doesn’t offer adjustable shock absorbers.

For better handling and stability, the track (width between the wheels) on the A7 is 3 inches wider in the front and 2.7 inches wider in the rear than the average track on the Q70.

For better maneuverability, the A7’s turning circle is .3 feet tighter than the Q70’s (36.4 feet vs. 36.7 feet). The A7’s turning circle is 1 foot tighter than the Q70 AWD’s (36.4 feet vs. 37.4 feet).

Cargo Capacity

The A7 has a much larger trunk than the Q70 (24.9 vs. 14.9 cubic feet).

The A7’s standard rear seats fold to accommodate long and bulky cargo. The Q70 doesn’t offer folding rear seats, only a ski pass-through.

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 Q70 doesn’t offer a power or hands-free opening trunk.

Ergonomics

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 Q70 doesn’t offer a heads-up display.

The power windows standard on both the A7 and the Q70 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 Q70 prevents the driver from operating the other windows just as it does the other passengers.

The A7’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Q70’s rear power window switches have to be held the entire time to open or close them fully.

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 Q70 doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the A7 detect other vehicles which could be blinded and automatically switch to low beams. The Q70 doesn’t offer automatic dimming high beams.

Standard smartphone integration for the A7 allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations and other connected activities without taking their eyes off the road or their hands from the wheel. The Q70 doesn’t offer factory integrated smartphone program access.
