Safety

For enhanced safety, the front and middle seat shoulder belts of the Audi Q7 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 QX80 doesn’t offer pretensioners for the middle seat belts.

Both the Q7 and QX80 have child safety locks to prevent children from opening the rear doors. The Q7 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 QX80’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 Q7 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 QX80 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 Q7. But it costs extra on the QX80.

When descending a steep, off-road slope, the Q7’s standard Hill Descent Assist allows you to creep down safely. The QX80 doesn’t offer Hill Descent Assist.

A passive infrared night vision system optional on the Q7 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 QX80 doesn’t offer a night vision system.

For better protection of the passenger compartment, the Q7 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The QX80 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Q7 and the QX80 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, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Q7 the rating of “Top Pick” for 2017, a rating granted to only 139 vehicles tested by the IIHS. The QX80 has not been tested, yet.

Warranty

The Q7’s corrosion warranty is 5 years longer than the QX80’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 Q7’s warranty.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Q7’s reliability 36 points higher than the QX80.

Fuel Economy and Range

On the EPA test cycle the Q7 55 TFSI V6 gets better fuel mileage than the QX80 AWD (19 city/25 hwy vs. 13 city/19 hwy).

In heavy traffic or at stoplights the Q7’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 QX80 doesn’t offer an automatic engine start/stop system.

Transmission

An eight-speed automatic is available on the Audi Q7, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the QX80.

Brakes and Stopping

For better stopping power the Q7’s brake rotors are larger than those on the QX80:

Consumer Reports

Tires and Wheels

For better traction, the Q7’s optional tires are larger than the largest tires available on the QX80 (285/45R20 vs. 275/60R20).

The Q7’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the QX80’s optional 50 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Q7 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The QX80 doesn’t offer run-flat tires.

Suspension and Handling

The Q7 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 or off-road. The QX80’s suspension doesn’t offer adjustable shock absorbers.

The Q7 Prestige handles at .85 G’s, while the QX80 AWD pulls only .72 G’s of cornering force in a Car and Driver skidpad test.

The Q7 Premium Plus executes Motor Trend’s “Figure Eight” maneuver 2.2 seconds quicker than the QX80 AWD (26.4 seconds @ .68 average G’s vs. 28.6 seconds @ .57 average G’s).

For better maneuverability, the Q7’s turning circle is .6 feet tighter than the QX80’s (40.7 feet vs. 41.3 feet).

For greater off-road capability the Q7 w/Air Suspension has a greater minimum ground clearance than the QX80 (9.7 vs. 9.2 inches), allowing the Q7 to travel over rougher terrain without being stopped or damaged.

Chassis

The Audi Q7 may be more efficient, handle and accelerate better because it weighs about 800 to 950 pounds less than the Infiniti QX80.

The Q7 is 10.6 inches shorter than the QX80, making the Q7 easier to handle, maneuver and park in tight spaces.

The Q7 is 7.3 inches shorter in height than the QX80, making the Q7 much easier to wash and garage and drive (lower center of gravity).

Unibody construction lowers the Q7’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The QX80 uses body-on-frame design instead.

The design of the Audi Q7 amounts to more than styling. The Q7 has an aerodynamic coefficient of drag of .333 Cd (optional .32 Cd with Air Suspension). That is significantly lower than the QX80 (.367) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Q7 get better fuel mileage.

Passenger Space

The Q7 has 2.1 inches more front legroom and .4 inches more third row legroom than the QX80.

The front step up height for the Q7 is 4.1 inches lower than the QX80 (18.6” vs. 22.7”). The Q7’s rear step up height is 4.8 inches lower than the QX80’s (18.7” vs. 23.5”).

Cargo Capacity

A low lift-over cargo hatch design makes loading and unloading the Q7 easier. The Q7’s cargo hatch lift-over height is 32.5 inches, while the QX80’s liftover is 35.8 inches.

To make loading groceries and cargo easier when your hands are full, the Q7’s liftgate can be opened and closed just by waving your foot, leaving your hands completely free. The QX80 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Ergonomics

Unlike the driver-only memory system in the QX80, the Q7 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 Q7 Prestige has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The QX80 doesn’t offer a heads-up display.

The power windows standard on both the Q7 and the QX80 have locks to prevent small children from operating them. When the lock on the Q7 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX80 prevents the driver from operating the other windows just as it does the other passengers.

To better shield the driver and front passenger’s vision, the Q7 has standard dual-element sun visors that can block glare from two directions simultaneously. The QX80 doesn’t offer secondary sun visors.

A manual rear sunshade is optional in the Q7 to help block heat and glare for the rear passengers. The QX80 doesn’t offer a rear sunshade.

Standard Audi Connect for the Q7 allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, finding fuel prices at nearby service stations, searching the internet and other connected activities without taking their eyes off the road or their hands from the wheel. The QX80 doesn’t offer factory integrated smartphone program access.

Economic Advantages

According to The Car Book by Jack Gillis, the Q7 is less expensive to operate than the QX80 because typical repairs cost much less on the Q7 than the QX80, including $617 less for a power steering pump.

Recommendations

Consumer Reports® recommends both the Audi Q7 and the Infiniti QX80, based on reliability, safety and performance.

The Q7 was chosen as one of Car and Driver’s “Top Five/10Best Trucks” for 2 of the last 2 years. The QX80 has never been a Car and Driver “Top Five/10Best Truck” pick.

The Audi Q7 outsold the Infiniti QX80 by over two to one during the 2018 model year.
