Compare the2025 Cadillac XT5VS 2024 Audi Q8

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 XT5 are reminded to check the back seat if they opened the rear door before starting out. The Q8 doesn’t offer a back seat reminder.

The Cadillac XT5 has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Q8 doesn’t offer knee airbags.

Both the XT5 and the Q8 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, blind spot warning systems, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Cadillac XT5 is safer than the Audi Q8:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Cadillac XT5 is safer than the Audi Q8:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Cadillac’s powertrain warranty covers the XT5 2 years and 20,000 miles longer than Audi covers the Q8. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Q8 ends after only 4 years or 50,000 miles.

There are over 85 percent more Cadillac dealers than there are Audi dealers, which makes it much easier should you ever need service under the XT5’s warranty.

To reliably start during all conditions and help handle large electrical loads, the XT5 has a standard 730-amp battery. The Q8’s 380-amp battery isn’t as powerful.

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 XT5’s reliability 15 points higher than the Q8.

J.D. Power and Associates rated the XT5 first among midsize premium suvs in their 2024 Initial Quality Study. The Q8 isn’t in the top three in its category.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Cadillac vehicles are better in initial quality than Audi vehicles. With 28 fewer problems per 100 vehicles, JD Power ranks Cadillac higher than Audi.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Cadillac vehicles are more reliable than Audi With 79 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Cadillac higher than Audi.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Cadillac vehicles are more reliable than Audi vehicles. Consumer Reports ranks Cadillac 3 places higher in reliability than Audi.

On the EPA test cycle the XT5 gets better mileage than the Q8:

An engine control system that can shut down some of the engine’s cylinders helps improve the XT5’s fuel efficiency. The Q8 doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Cadillac XT5 uses regular unleaded gasoline (premium recommended with the 2.0 turbo 4-cylinder engine for maximum performance). The Q8 requires premium, which can cost on average about 84.9 cents more per gallon.

The XT5 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 Q8 doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Cadillac XT5 higher (6 to 7 out of 10) than the Audi Q8 (4). This means the XT5 produces up to 13.2 pounds less smog-producing pollutants than the Q8 every 15,000 miles.

A nine-speed automatic is standard on the Cadillac XT5, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Q8.

The XT5 stops much shorter than the Q8:

The Cadillac XT5’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Audi Q8 only has 5 wheel lugs per wheel.

For better maneuverability, the XT5’s turning circle is 4.9 feet tighter than the Q8’s (38.7 feet vs. 43.6 feet). The XT5 w/20” wheels’ turning circle is 4.6 feet tighter than the Q8’s (39 feet vs. 43.6 feet).

For greater off-road capability the XT5 has a 2 inches greater minimum ground clearance than the Q8 (7.8 vs. 5.8 inches), allowing the XT5 to travel over rougher terrain without being stopped or damaged.

The Cadillac XT5 may be more efficient, handle and accelerate better because it weighs about 700 to 1150 pounds less than the Audi Q8.

The XT5 is 7 inches shorter than the Q8, making the XT5 easier to handle, maneuver and park in tight spaces.

The front grille of the XT5 2.0 Turbo uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Q8 doesn’t offer active grille shutters.

The XT5 has 2.6 inches more front headroom and .3 inches more rear headroom than the Q8.

The XT5 has a larger cargo volume with its rear seat folded than the Q8 with its rear seat folded (63 vs. 60.7 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the XT5 easier. The XT5’s cargo hatch lift-over height is 30.9 inches, while the Q8’s liftover is 33.7 inches.

The XT5’s cargo area is larger than the Q8’s in almost every dimension:

Pulling a handle automatically lowers the XT5’s rear seats, to make changing between passengers and cargo easier. The Q8 doesn’t offer automatic folding seats.

Standard Trailer Sway Control on the XT5 uses the StabiliTrak® sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The Q8 doesn’t offer electronic trailer sway control.

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Audi. J.D. Power ranks Cadillac fifth in service department satisfaction. With a 29% lower rating, Audi is ranked 18th.

The XT5’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Q8 does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the XT5 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Q8 only has an intermittent setting, so in a hard rain visibility isn’t as good.

The XT5 is available in both front-wheel drive and four-wheel drive configurations. The Q8 doesn’t offer a two-wheel drive configuration.

Insurance will cost less for the XT5 owner. The Complete Car Cost Guide estimates that insurance for the XT5 will cost $4610 to $7220 less than the Q8 over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Cadillac XT5 will be $28124 to $28171 less than for the Audi Q8.

Consumer Reports® recommends the Cadillac XT5, based on reliability, safety and performance.

The Cadillac XT5 outsold the Audi Q8/SQ8/RS Q8 by almost two to one during 2023.
