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 XT6 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.

Both the XT6 and the Q7 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive, night vision systems and around view monitors.

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Cadillac XT6 is safer than the Q7:

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the XT6 its highest rating: “Top Pick Plus” for 2020, a rating granted to only 30 vehicles tested by the IIHS. The Q7 has not been fully tested, yet.

Cadillac’s powertrain warranty covers the XT6 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 3 times as many Cadillac dealers as there are Audi dealers, which makes it much easier should you ever need service under the XT6’s warranty.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Cadillac vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Cadillac 17th in initial quality. With 6 more problems per 100 vehicles, Audi is ranked 22nd.

An engine control system that can shut down some of the engine’s cylinders helps improve the XT6’s fuel efficiency. The Q7 doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Cadillac XT6 uses regular unleaded gasoline. The Q7 requires premium, which can cost 20 to 55 cents more per gallon.

The XT6 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.

For better ride, handling and brake cooling the XT6 has standard 20-inch wheels. Smaller 19-inch wheels are standard on the Q7.

The Cadillac XT6’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 XT6 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 better maneuverability, the XT6’s turning circle is 1.9 feet tighter than the Q7’s (39.1 feet vs. 41 feet).

The Cadillac XT6 may be more efficient, handle and accelerate better because it weighs about 350 to 400 pounds less than the Audi Q7.

The XT6 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 XT6 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.

To help drivers avoid possible obstacles, the XT6 has standard cornering lights to illuminate around corners when the turn signals are activated. The Q7 doesn’t offer cornering lights.

The XT6 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the Q7.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Cadillac XT6 has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Q7.

The XT6’s optional Automatic Park Assist can parallel park or back into a parking spot by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The Q7 doesn’t offer an automated parking system.
