Compare the2023 Acura RDXVS 2023 Audi Q5

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 Q5 doesn’t offer knee airbags.

Both the RDX and the Q5 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, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.

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 Q5:

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

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the RDX is 1.4% less likely to roll over than the Q5.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the RDX its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 29 vehicles tested by the IIHS. The Q5 has not been fully tested, yet.

Acura’s powertrain warranty covers the RDX 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.

Acura pays for scheduled maintenance on the RDX for 2 years and 24,000 miles. Acura will pay for oil changes, lubrication and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the Q5.

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 16 points higher than the Q5.

J.D. Power and Associates’ 2022 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 47 fewer problems per 100 vehicles, JD Power ranks Acura higher than Audi.

The RDX’s 2.0 turbo 4-cylinder produces 71 more horsepower (272 vs. 201) and 44 lbs.-ft. more torque (280 vs. 236) than the Q5 40 TFSI’s standard 2.0 turbo 4-cylinder hybrid. The RDX’s 2.0 turbo 4-cylinder produces 11 more horsepower (272 vs. 261) and 7 lbs.-ft. more torque (280 vs. 273) than the Q5 45 TFSI’s standard 2.0 turbo 4-cylinder hybrid.

The RDX has 2.8 gallons more fuel capacity than the Q5 Hybrid’s standard fuel tank (17.1 vs. 14.3 gallons), for longer range between fill-ups.

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 Q5 doesn’t offer a cap-less fueling system.

A 10-speed automatic is standard on the Acura RDX, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Q5.

The RDX stops much shorter than the Q5:

The RDX’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 RDX has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Q5.

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 Q5 doesn’t offer vehicle monitored tire inflation.

For better handling and stability, the track (width between the wheels) on the RDX is .6 inches wider in the front and 1.4 inches wider in the rear than on the Q5.

The RDX A-Spec AWD handles at .83 G’s, while the Q5 45 TFSI Premium Plus pulls only .81 G’s of cornering force in a Car and Driver skidpad test.

For greater off-road capability the RDX has a greater minimum ground clearance than the Q5 55 TFSI e (8.2 vs. 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 300 to 550 pounds less than the Audi Q5.

The RDX 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 RDX has .7 inches more front legroom, 2 inches more front shoulder room, .4 inches more rear legroom and .1 inches more rear shoulder room than the Q5.

The RDX has a much larger cargo volume with its rear seat up than the Q5 with its rear seat up (31.1 vs. 25.8 cubic feet). The RDX has a much larger cargo volume with its rear seat folded than the Q5 with its rear seat folded (79.8 vs. 54 cubic feet).

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.

The RDX offers a 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 RDX’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Q5.

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 Q5 only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the RDX’s headlight performance “Good,” a higher rating than the Q5’s headlights, which were rated “Fair.”

The RDX is available in both front-wheel drive and four-wheel drive configurations. The Q5 doesn’t offer a two-wheel drive configuration.

Insurance will cost less for the RDX owner. The Complete Car Cost Guide estimates that insurance for the RDX will cost $2070 to $4645 less than the Q5 over a five-year period.

According to The Car Book by Jack Gillis, the RDX is less expensive to operate than the Q5 because it costs $64 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the RDX than the Q5, including $294 less for a water pump, $394 less for a muffler, $207 less for a starter, $207 less for fuel injection, $64 less for a fuel pump, $164 less for front struts and $461 less for a timing belt/chain.
