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 Q5 doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The XT6 offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Q5 doesn’t offer backup collision prevention brakes.
A passive infrared night vision system optional on the XT6 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 Q5 doesn’t offer a night vision system.
Both the XT6 and the Q5 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, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive and around view monitors.
Cadillac’s powertrain warranty covers the XT6 2 years and 20,000 miles longer than Audi covers the Q5. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Q5 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.
To reliably power the ignition and other systems and to recharge the battery, the XT6 has a standard 155-amp alternator (170-amp - XT6 optional). The Q5’s standard 110-amp alternator and largest (optional) 150-amp alternator aren’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.
The XT6’s 3.6 DOHC V6 produces 62 more horsepower (310 vs. 248) than the Q5’s 2.0 turbo 4-cyl.
An engine control system that can shut down half of the engine’s cylinders helps improve the XT6’s fuel efficiency. The Q5 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 Q5 requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.
The XT6 AWD’s standard fuel tank has 3.5 gallons more fuel capacity than the Q5 (22 vs. 18.5 gallons).
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 Q5 doesn’t offer a cap-less fueling system.
A nine-speed automatic is standard on the Cadillac XT6, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Q5.
For better traction, the XT6Sport’s optional tires are larger than the largest tires available on the Q5 (265/45R21 vs. 255/45R20).
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 Q5’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 Q5. The XT6Sport’s optional 21-inch wheels are larger than the 20-inch wheels optional on the Q5.
The Cadillac XT6’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Audi Q5 only has 5 wheel lugs per wheel.
The XT6 offers an optional 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 Q5’s suspension doesn’t offer adjustable shock absorbers.
For a smoother ride and more stable handling, the XT6’s wheelbase is 1.7 inches longer than on the Q5 (112.7 inches vs. 111 inches).
For better handling and stability, the track (width between the wheels) on the XT6 is 2.8 inches wider in the front and 2.9 inches wider in the rear than on the Q5.
The XT6 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Q5 doesn’t offer active noise cancellation.
The XT6 has standard seating for 7 passengers; the Q5 can only carry 5.
The XT6 has .2 inches more front legroom, .6 inches more front shoulder room, 1.3 inches more rear legroom and .9 inches more rear shoulder room than the Q5.
The XT6’s cargo area provides more volume than the Q5.

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.
The XT6 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Q5 doesn’t offer a remote starting system.
The XT6’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The Q5 doesn’t offer an easy entry system.
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 Q5 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 Q5 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 Q5.
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. Only the Q5 Premium Plus/Prestige offers wireless charging.
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 Q5 Prestige’s automatic parking system requires operating the brakes and transmission to safely park.
The XT6 is available in both front-wheel drive and four-wheel drive configurations. The Q5 doesn’t offer a two-wheel drive configuration.
