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 GMC Acadia doesn’t offer pretensioners for the middle seat belts.

Both the Q7 and Acadia 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 Acadia’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 Acadia 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 Acadia doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q7. But it costs extra on the Acadia.

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 Acadia doesn’t offer a night vision system.

Both the Q7 and the Acadia 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, daytime running lights, rearview cameras, available 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 Audi Q7 is safer than the GMC Acadia:

The Q7’s corrosion warranty is 6 years and unlimited miles longer than the Acadia’s (12/unlimited vs. 6/100,000).

For better traction, the Q7 has larger standard tires than the Acadia (255/55R19 vs. 235/65R18). The Q7’s optional tires are larger than the largest tires available on the Acadia (285/45R20 vs. 255/65R17).

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 Acadia’s standard 65 series tires. The Q7 Prestige’s optional tires have a lower 35 series profile than the Acadia’s optional 55 series tires.

For better ride, handling and brake cooling the Q7 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Acadia. The Q7 Prestige’s optional 22-inch wheels are larger than the 20-inch wheels optional on the Acadia.

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 Acadia doesn’t offer run-flat tires.

For a smoother ride and more stable handling, the Q7’s wheelbase is 5.4 inches longer than on the Acadia (117.9 inches vs. 112.5 inches).

For better handling and stability, the track (width between the wheels) on the Q7 is 1.6 inches wider in the front and 2.1 inches wider in the rear than on the Acadia.

The Q7 Prestige handles at .86 G’s, while the Acadia Denali AWD pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

The Q7 Premium Plus executes Motor Trend’s “Figure Eight” maneuver quicker than the Acadia SLT AWD (26.4 seconds @ .68 average G’s vs. 26.9 seconds @ .67 average G’s).

For greater off-road capability the Q7 has a 1.1 inches greater minimum ground clearance than the Acadia (8.3 vs. 7.2 inches), allowing the Q7 to travel over rougher terrain without being stopped or damaged. The Q7 w/Air Suspension’s minimum ground clearance is 1.9 inches higher than on the Acadia All Terrain (9.7 vs. 7.8 inches).

The Q7’s standard towing capacity is much higher than the Acadia’s (4400 vs. 1000 pounds). Maximum trailer towing in the GMC Acadia is only 4000 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 Acadia. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Audi service is better than GMC. J.D. Power ranks Audi 8th in service department satisfaction (above the industry average). With a 17% lower rating, GMC is ranked 14th.

Unlike the driver-only memory seat and mirrors optional at extra cost in the Acadia (except SL/SLE/AT4), 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 Acadia doesn’t offer a heads-up display.

The Q7’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 Acadia’s rear power window switches have to be held the entire time to open them fully. Only its driver’s window closes automatically.

If the windows are left open on the Q7 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Acadia can only operate the windows from inside the vehicle, with the ignition on.

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 Acadia 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 Acadia’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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 Acadia 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 Acadia doesn’t offer a rear sunshade.

The Q7 Prestige offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Acadia.

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 Acadia is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the Q7 is less expensive to operate than the Acadia 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 Acadia, including $87 less for a water pump, $8 less for front brake pads, $45 less for a fuel pump and $555 less for a power steering pump.

Consumer Reports® recommends the Audi Q7, 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 Acadia has never been a Car and Driver “Top Five/10Best Truck” pick.
