Compare the2024 Acura RDXVS 2024 Audi Q8

The Acura RDX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help 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 RDX 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, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

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

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

The Acura RDX achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Q8 has not yet been fully evaluated by the IIHS for 2024.

Acura’s powertrain warranty covers the RDX 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.

Acura pays for scheduled maintenance on the RDX for 2 years and 24,000 miles. Acura will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the Q8.

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 RDX’s reliability 36 points higher than the Q8.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Acura vehicles are better in initial quality than Audi vehicles. With 14 fewer problems per 100 vehicles, JD Power ranks Acura higher than Audi.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Acura vehicles are more reliable than Audi vehicles. Consumer Reports ranks Acura fourth in overall reliability. Audi is ranked 19th.

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

To lower fuel costs and make buying fuel easier, the Acura RDX uses regular unleaded gasoline (premium recommended for maximum performance). The Q8 requires premium, which can cost on average about 82.8 cents more per gallon.

The RDX 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 Acura RDX higher (6 out of 10) than the Audi Q8 (4). This means the RDX produces up to 12.1 pounds less smog-producing pollutants than the Q8 every 15,000 miles.

A 10-speed automatic is standard on the Acura RDX, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Q8.

The RDX stops much shorter than the Q8:

The RDX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Q8 doesn’t offer vehicle monitored tire inflation.

For better maneuverability, the RDX’s turning circle is 4.7 feet tighter than the Q8’s (38.9 feet vs. 43.6 feet).

For greater off-road capability the RDX has a 2.4 inches greater minimum ground clearance than the Q8 (8.2 vs. 5.8 inches), allowing the RDX to travel over rougher terrain without being stopped or damaged.

The Acura RDX may be more efficient, handle and accelerate better because it weighs about 1000 to 1050 pounds less than the Audi Q8.

The RDX is 9.2 inches shorter than the Q8, making the RDX easier to handle, maneuver and park in tight spaces.

The RDX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Q8 doesn’t offer active noise cancellation.

The RDX has 2.5 inches more front headroom, .2 inches more front shoulder room and .2 inches more rear headroom than the Q8.

The RDX has a larger cargo volume with its rear seat up than the Q8 with its rear seat up (31.1 vs. 30.5 cubic feet). The RDX has a larger cargo volume with its rear seat folded than the Q8 with its rear seat folded (79.8 vs. 60.7 cubic feet).

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

J.D. Power and Associates surveys of service recipients show that Acura service is better than Audi. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 6% lower rating, Audi is ranked 8th.

To improve rear visibility by keeping the rear window clear, the RDX 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 Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The RDX’s headlights were rated “Good” by the IIHS, while the Q8’s headlights are rated “Acceptable.”

Insurance will cost less for the RDX owner. The Complete Car Cost Guide estimates that insurance for the RDX will cost $5520 to $7970 less than the Q8 over a five-year period.

The RDX will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the RDX will retain 53.7% to 55% of its original price after five years, while the Q8 only retains 51.58% to 51.73%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Acura RDX will be $33389 to $35448 less than for the Audi Q8.
