For enhanced safety, the front and middle seat shoulder belts of the Infiniti QX80 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 Audi Q7 doesn’t offer height-adjustable middle seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the QX80 are reminded to check the back seat if they opened the rear door before starting out. The Q7 doesn’t offer a back seat reminder.

The QX80 has standard Active Head Restraints (AHR), which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the AHR system moves the headrests forward to prevent neck and spine injuries. The Q7 doesn’t offer a whiplash protection system.

Both the QX80 and the Q7 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front 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, rearview cameras, available all wheel drive, lane departure warning systems, blind spot warning systems and rear cross-path warning.

The Infiniti QX80 weighs 594 to 1137 pounds more than the Audi Q7. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

To lower fuel costs and make buying fuel easier, the Infiniti QX80 uses regular unleaded gasoline (premium recommended for maximum performance). The Q7 requires premium, which can cost 20 to 55 cents more per gallon.

The QX80 has 6.2 gallons more fuel capacity than the Q7 45 TFSI’s standard fuel tank (26 vs. 19.8 gallons), for longer range between fill-ups. The QX80 has 3.5 gallons more fuel capacity than the Q7 55 TFSI’s standard fuel tank (26 vs. 22.5 gallons).

For better traction, the QX80 has larger tires than the Q7 (275/60R20 vs. 255/55R19).

For better ride, handling and brake cooling the QX80 has standard 20-inch wheels. Smaller 19-inch wheels are standard on the Q7.

The Infiniti QX80’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Audi Q7 only has 5 wheel lugs per wheel.

The QX80 has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the Q7; 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. Some tire options on the Q7 don’t have a run-flat feature, either.

The rear suspension of the QX80 uses air springs for a smoother, controlled ride than the Q7, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The QX80 offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Audi doesn’t offer an active suspension on the Q7.

The QX80 has a standard automatic rear load leveling suspension to keep ride height level with a heavy load or when towing. The Q7 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the QX80’s wheelbase is 3.2 inches longer than on the Q7 (121.1 inches vs. 117.9 inches).

For better handling and stability, the track (width between the wheels) on the QX80 is 1.4 inches wider in the front and 1.3 inches wider in the rear than on the Q7.

For greater off-road capability the QX80 has a greater minimum ground clearance than the Q7 (9.2 vs. 8.3 inches), allowing the QX80 to travel over rougher terrain without being stopped or damaged.

The QX80’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Q7 does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the QX80 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Q7 only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the QX80’s headlight performance “Very Good,” a higher rating than the Q7’s headlights, which were rated “Good.”

To help drivers see further while navigating curves, the QX80 offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Q7 doesn’t offer cornering lights.

The QX80 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the Q7.

The QX80 offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Q7 doesn’t offer a house-current electrical outlet.
