For enhanced safety, the Buick Enclave’s middle seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Audi Q7 doesn’t offer comfort guides on its 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 Enclave 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 Enclave has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Q7 doesn’t offer front seat center airbags.

Both the Enclave and the Q7 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Buick Enclave is safer than the Audi Q7:

Buick’s powertrain warranty covers the Enclave 2 years and 20,000 miles longer than Audi covers the Q7. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Q7 ends after only 4 years or 50,000 miles.

There are almost 7 times as many Buick dealers as there are Audi dealers, which makes it much easier should you ever need service under the Enclave’s warranty.

To lower fuel costs and make buying fuel easier, the Buick Enclave uses regular unleaded gasoline. The Q7 requires premium, which can cost 20 to 55 cents more per gallon.

The Enclave has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Q7 doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Buick Enclave higher (6 out of 10) than the Audi Q7 (3). This means the Enclave produces up to 23.4 pounds less smog-producing pollutants than the Q7 every 15,000 miles.

The Buick Enclave’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 Enclave has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Q7 doesn’t offer vehicle monitored tire inflation.

The Enclave has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire 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.

For a smoother ride and more stable handling, the Enclave’s wheelbase is 3 inches longer than on the Q7 (120.9 inches vs. 117.9 inches).

For better handling and stability, the track (width between the wheels) on the Enclave is 1.2 inches wider in the front and .4 inches wider in the rear than on the Q7.

For better maneuverability, the Enclave’s turning circle is 2 feet tighter than the Q7’s (39 feet vs. 41 feet).

The Buick Enclave may be more efficient, handle and accelerate better because it weighs about 400 to 450 pounds less than the Audi Q7.

The front grille of the Enclave uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Q7 doesn’t offer active grille shutters.

The Enclave uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Q7 doesn’t offer active noise cancellation.

To improve rear visibility by keeping the rear window clear, the Enclave 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 Enclave’s headlight performance “Very Good,” a higher rating than the Q7’s headlights, which were rated “Good.”

The Enclave (except Preferred) 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.
