Safety

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, rearview cameras, available all wheel drive, night vision systems and around view monitors.

Warranty

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.

Reliability

To reliably power the ignition and other systems and to recharge the battery, the XT6 has a standard 155-amp alternator. The Q7’s standard 120-amp alternator isn’t as powerful.

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.

Engine

The XT6’s 3.6 DOHC V6 produces 62 more horsepower (310 vs. 248) than the Q7 45 TFSI’s standard 2.0 turbo 4-cyl.

Fuel Economy and Range

An engine control system that can shut down half 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 for maximum efficiency, 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.

Transmission

A nine-speed automatic is standard on the Cadillac XT6, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Q7.

Tires and Wheels

The XT6’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 Q7 2.0T’s standard 60 series tires.

For better ride, handling and brake cooling the XT6 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Q7 2.0T.

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 models of the Q7 don’t even offer run-flats.

Suspension and Handling

For better maneuverability, the XT6’s turning circle is 1.6 feet tighter than the Q7’s (39.1 feet vs. 40.7 feet).

Chassis

The Cadillac XT6 may be more efficient, handle and accelerate better because it weighs about 300 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.

Passenger Space

The XT6 has 1.4 inches more front headroom, .3 inches more rear headroom, .3 inches more rear legroom, 1.3 inches more third row headroom, .3 inches more third row legroom and 4.1 inches more third row shoulder room than the Q7.

Cargo Capacity

The XT6’s cargo area provides more volume than the Q7.

Pressing a switch automatically lowers the XT6’s second and third row seats, to make changing between passengers and cargo easier. The Q7 doesn’t offer automatic folding second row seats.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Audi. J.D. Power ranks Cadillac third in service department satisfaction. With a 23% lower rating, Audi is ranked 8th.

Ergonomics

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.

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.

Model Availability

The XT6 is available in both front-wheel drive and four-wheel drive configurations. The Q7 doesn’t offer a two-wheel drive configuration.
