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 Buick Enclave doesn’t offer pretensioners for the middle seat belts.

The Q7’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Enclave doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Audi Q7 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 Buick Enclave doesn’t offer height-adjustable front seat belts.

Both the Q7 and Enclave 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 Enclave’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 Enclave 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.

Over 200 people are killed each year when backed over by motor vehicles. The Q7 offers an optional backup collision prevention system that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Enclave doesn’t offer backup collision prevention brakes.

The Q7 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Enclave doesn’t offer all-wheel drive.

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 Enclave doesn’t offer a night vision system.

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

The Enclave has not been tested, yet.

On the EPA test cycle the Q7 45 TFSI gets better fuel mileage than the Enclave AWD (19 city/25 hwy vs. 17 city/25 hwy).

Regenerative brakes improve the Q7 55 TFSI’s fuel efficiency by converting inertia back into energy instead of wasting it. The Enclave doesn’t offer a regenerative braking system.

For better traction, the Q7’s optional tires are larger than the largest tires available on the Enclave (285/45R20 vs. 255/65R18).

The Q7’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Enclave’s standard 65 series tires. The Q7 Prestige’s optional tires have a lower 35 series profile than the Enclave’s optional 55 series tires.

For better ride, handling and brake cooling the Q7 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Enclave. The Q7 Prestige’s optional 22-inch wheels are larger than the 20-inch wheels optional on the Enclave.

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 Enclave doesn’t offer run-flat tires.

The Q7 Prestige handles at .86 G’s, while the Enclave Essence pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

The Q7 Premium Plus executes Motor Trend’s “Figure Eight” maneuver 2 seconds quicker than the Enclave Avenir (26.4 seconds @ .68 average G’s vs. 28.4 seconds @ .6 average G’s).

For greater off-road capability the Q7 has a greater minimum ground clearance than the Enclave (8.3 vs. 7.7 inches), allowing the Q7 to travel over rougher terrain without being stopped or damaged. The Q7 w/Air Suspension’s minimum ground clearance is 2 inches higher than on the Enclave (9.7 vs. 7.7 inches).

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Q7. The Enclave doesn’t offer locking storage for small valuables.

The Q7’s standard towing capacity is much higher than the Enclave’s (4400 vs. 1500 pounds). Maximum trailer towing in the Buick Enclave is only 5000 pounds. The Q7 offers up to a 7700 lbs. towing capacity.

The engine in the Q7 is mounted longitudinally (North-South), instead of sideways, as in the Enclave. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Unlike the driver-only memory system in the Enclave Premium/Avenir, 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 Enclave doesn’t offer a heads-up display.

The Q7’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Enclave’s passenger windows don’t close automatically.

The Q7 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The Enclave doesn’t offer a locking fuel door.

The Q7’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Enclave’s manually variable intermittent wipers have to be constantly adjusted.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Q7 Prestige has standard headlight washers to keep headlight output high. The Enclave doesn’t offer headlight washers.

A manual rear sunshade and rear side window sunshades are optional in the Q7 (except Premium) to help block heat and glare for the rear passengers. The Enclave doesn’t offer a rear sunshade.

Insurance will cost less for the Q7 owner. The Car Book by Jack Gillis rates the Q7 with a number “5” insurance rate while the Enclave is rated higher at a number “10” rate.

The Q7 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Q7 will retain 44.87% to 44.98% of its original price after five years, while the Enclave only retains 34.43% to 39.22%.

According to The Car Book by Jack Gillis, the Q7 is less expensive to operate than the Enclave because it costs $127 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Q7 than the Enclave, including $307 less for a water pump, $17 less for front brake pads, $123 less for a fuel pump and $649 less for a power steering pump.

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

The Q7 was chosen as one of Car and Driver’s “Top Five/10Best Trucks” for 3 of the last 4 years. The Enclave has never been a Car and Driver “Top Five/10Best Truck” pick.
