Safety

For enhanced safety, the front shoulder belts of the Cadillac XT5 are height-adjustable, and the rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Audi Q8 has only front height-adjustable seat belts.

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.

Over 200 people are killed each year when backed over by motor vehicles. The XT5 offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Q8 doesn’t offer backup collision prevention brakes.

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, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the XT5 the rating of “Top Pick” for 2017, a rating granted to only 154 vehicles tested by the IIHS. The Q8 has not been tested, yet.

Warranty

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 almost 3 times as many Cadillac dealers as there are Audi dealers, which makes it much easier should you ever need service under the XT5’s warranty.

Reliability

J.D. Power and Associates’ 2018 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 12th in initial quality, above the industry average. With 15 more problems per 100 vehicles, Audi is ranked 25th, below the industry average.

Fuel Economy and Range

An engine control system that can shut down half 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. The Q8 requires premium for maximum efficiency, which can cost 20 to 55 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.

Tires and Wheels

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.

Suspension and Handling

For better maneuverability, the XT5’s turning circle is 4.8 feet tighter than the Q8’s (38.7 feet vs. 43.5 feet). The XT5 w/20” wheels’ turning circle is 4.5 feet tighter than the Q8’s (39 feet vs. 43.5 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.

Chassis

The Cadillac XT5 may be more efficient, handle and accelerate better because it weighs about 650 to 1000 pounds less than the Audi Q8.

The XT5 is 6.8 inches shorter than the Q8, making the XT5 easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The XT5 has a much larger cargo volume than the Q8 with its rear seat up (30 vs. 28.6 cubic feet).

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

Ergonomics

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’s optional Automatic Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Q8 doesn’t offer an automated parking system.

Model Availability

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

Recommendations

The Cadillac XT5 outsold the Audi Q8 by almost 30 to one during 2018.
