Safety Comparison

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.

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

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 Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. The Acadia doesn’t offer a whiplash protection system.

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

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

The Q7’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Acadia doesn’t offer a lane departure warning system.

The Q7 has standard Parktronic ® to help warn the driver about vehicles, pedestrians or other obstacles behind or, optionally, in front of the vehicle. The Acadia doesn’t offer a front parking aid.

Both the Q7 and the Acadia have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, height-adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

The Audi Q7 weighs 434 to 911 pounds more than the GMC Acadia. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty Comparison

The Q7 comes with a full 4 year/50,000 mile basic warranty, which covers the entire truck and includes 24 hour roadside assistance. The Acadia’s 3 year/36,000 mile basic warranty expires 1 year and 14,000 miles sooner.

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

Audi pays for scheduled maintenance on the Q7 for 1 year and 5000 miles. Audi will pay for oil changes, tire rotation, lubrication and any other scheduled maintenance. GMC doesn’t pay scheduled maintenance for the Acadia.

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the Q7 has a standard 190-amp alternator. The Acadia’s 170-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2011 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than GMC vehicles. J.D. Power ranks Audi 20th in reliability. With 23 more problems per 100 vehicles, GMC is ranked 26th.

Motor Trend

Tires and Wheels Comparison

For better traction, the Q7 S line Prestige’s optional tires are larger than the largest tires available on the Acadia (295/35R21 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 Acadia SL/SLE’s standard 65 series tires. The Q7 S line Prestige’s optional tires have a lower 35 series profile than the Acadia Denali’s 55 series tires.

For better ride, handling and brake cooling the Q7 S line Prestige offers optional 21-inch wheels. The Acadia’s largest wheels are only 20 inches.

Suspension and Handling Comparison

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 Acadia’s suspension doesn’t offer adjustable shock absorbers.

The Q7 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Q7’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Acadia doesn’t offer a load leveling suspension.

The Q7 S line Prestige handles at .85 G’s, while the Acadia SLT AWD pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the Q7’s turning circle is 1 foot tighter than the Acadia’s (39.4 feet vs. 40.4 feet).

For greater off-road capability the Q7 has a greater minimum ground clearance than the Acadia (8.1 vs. 7.4 inches), allowing the Q7 to travel over rougher terrain without being stopped or damaged. The Q7 air suspension’s minimum ground clearance is 2 inches higher than on the Acadia (9.4 vs. 7.4 inches).

Passenger Space Comparison

The front step up height for the Q7 is .5 inches lower than the Acadia (18.4” vs. 18.9”). The Q7’s rear step up height is 1.1 inches lower than the Acadia’s (18.7” vs. 19.8”).

Cargo Capacity Comparison

The Q7 has standard second and third row seats which fold flat into the floor. This completely clears a very large cargo area quickly. The Acadia only has a third row seat which folds into the floor. The Acadia’s second row seat doesn’t fold into the floor and eats up cargo room.

Ergonomics Comparison

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 standard power window switches have to be held the entire time to close them fully. Only its driver’s window opens automatically. With the Acadia’s optional power windows, only the driver’s window closes automatically and only the front windows open automatically.

If the windows are left down on the Q7 the driver can raise them all using the key in the outside lock cylinder; on a hot day the driver can lower the windows. The driver of the Acadia can only operate the windows from inside the vehicle, with the ignition on.

Audi Advanced Key optional on the Q7 allows the driver to unlock the doors, cargo door and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the car in bad weather or making a hurried start to your trip. The GMC Acadia doesn’t offer an advanced key system.

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 manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the Q7 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Acadia doesn’t offer heated windshield washer nozzles.

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 offers available headlight washers to keep headlight output high. The Acadia doesn’t offer headlight washers.

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

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 Acadia 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 Acadia doesn’t offer a rear sunshade.

When the Q7 is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Acadia’s mirror doesn’t automatically adjust for backing.

The Q7 has standard heated front seats. Heated front seats cost extra on the Acadia, and aren’t available on the Acadia SL. The Q7 also offers optional heated second row seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the Acadia.

The Q7’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Acadia SL doesn’t offer dual zone air conditioning.

The Q7’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Acadia SL doesn’t offer automatic air conditioning.

A built-in pollen filter removes pollen, exhaust fumes and other pollutants from the Q7’s passenger compartment. This helps prevent lung and/or sinus irritation, which can trigger allergies or asthma. The Acadia doesn’t offer a filtration system.

To keep a safe, consistent following distance, the Q7 offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Acadia doesn’t offer an adaptive cruise control.

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the Q7 is less expensive to operate than the Acadia because it costs $98 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Q7 than the Acadia, including $76 less for front brake pads, $99 less for fuel injection, $372 less for a fuel pump and $67 less for a power steering pump.
