Safety

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 Cadillac XT5 doesn’t offer pretensioners for the middle seat belts.

Both the Q7 and XT5 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 XT5’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 XT5 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q7. But it costs extra on the XT5.

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 XT5 doesn’t offer a night vision system.

Both the Q7 and the XT5 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 lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Q7’s reliability 38 points higher than the XT5.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Cadillac vehicles. J.D. Power ranks Audi 13th in reliability, above the industry average. With 45 more problems per 100 vehicles, Cadillac is ranked 27th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Cadillac vehicles. Consumer Reports ranks Audi 21 places higher in reliability than Cadillac.

Engine

The Q7 55 TFSI’s standard 3.0 supercharged V6 produces 19 more horsepower (329 vs. 310) and 54 lbs.-ft. more torque (325 vs. 271) than the XT5’s 3.6 DOHC V6.

As tested in Car and Driver the Q7 55 TFSI 3.0 supercharged V6 is faster than the Cadillac XT5:

Tires and Wheels

For better traction, the Q7 has larger standard tires than the XT5 (255/55R19 vs. 235/65R18). The Q7’s optional tires are larger than the largest tires available on the XT5 (285/45R20 vs. 235/65R18).

The Q7 2.0T’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the XT5’s standard 65 series tires. The Q7’s optional tires have a lower 40 series profile than the XT5’s optional 55 series tires.

For better ride, handling and brake cooling the Q7 offers optional 21-inch wheels. The XT5’s largest wheels are only 20-inches.

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 XT5 doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the Q7’s wheelbase is 5.4 inches longer than on the XT5 (117.9 inches vs. 112.5 inches).

For better handling and stability, the track (width between the wheels) on the Q7 is 1.7 inches wider in the front and 2.2 inches wider in the rear than on the XT5.

The Q7’s front to rear weight distribution is more even (55% to 45%) than the XT5’s (58.2% to 41.8%). This gives the Q7 more stable handling and braking.

The Q7 Prestige handles at .85 G’s, while the XT5 AWD pulls only .84 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 XT5 AWD (26.4 seconds @ .68 average G’s vs. 27.1 seconds @ .65 average G’s).

For greater off-road capability the Q7 has a greater minimum ground clearance than the XT5 (8.3 vs. 7.8 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 XT5 (9.7 vs. 7.8 inches).

Towing

The Q7’s standard towing capacity is much higher than the XT5’s (4400 vs. 1000 pounds). Maximum trailer towing in the Cadillac XT5 is only 3500 pounds. The Q7 offers up to a 7700 lbs. towing capacity.

Servicing Ease

The engine in the Q7 is mounted longitudinally (North-South), instead of sideways, as in the XT5. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Ergonomics

Unlike the driver-only memory system optional at extra cost in the XT5, 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’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 XT5’s rear power window switches have to be held the entire time to close them fully.

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 also lower the windows the same way. The driver of the XT5 can only close the windows from inside the vehicle, with the ignition on.

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 XT5’s standard 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 offers available headlight washers to keep headlight output high. The XT5 doesn’t offer headlight washers.

The XT5’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The Q7’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

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 XT5 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 XT5 doesn’t offer a rear sunshade.

Economic Advantages

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 XT5 is rated higher at a number “8” 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 4.96% to 83.4% of its original price after five years, while the XT5 only retains 42.64% to 43.55%.

According to The Car Book by Jack Gillis, the Q7 is less expensive to operate than the XT5 because it costs $171 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Q7 than the XT5, including $134 less for a water pump and $222 less for a power steering pump.

Recommendations

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 2 of the last 2 years. The XT5 has never been a Car and Driver “Top Five/10Best Truck” pick.
