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.

With its standard Collision Mitigation Braking System, the Acura RDX is better at preventing collisions with pedestrians than the Audi Q5, according to the Insurance Institute for Highway Safety:

	RDX	Q5

37 MPH Low beams	No Slowing	No Slowing

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, 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 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:

	RDX	Q5
	Front Seat
STARS	5 Stars	5 Stars
Chest Movement	.6 inches	.6 inches
Hip Force	217 lbs.	279 lbs.
	Rear Seat
STARS	5 Stars	5 Stars
HIC	124	185
Spine Acceleration	52 G’s	53 G’s
Hip Force	462 lbs.	817 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	11 inches	15 inches

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

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Acura RDX is safer than the Q5:

	RDX	Q5

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.

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 Q5 last would have qualified as a “Top Safety Pick” in 2023.

Warranty

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.

Reliability

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 38 points higher than the Audi Q5 and 42 points higher than the Audi Q5 55 TFSIe.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Acura vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Acura above average in initial quality. With 49 more problems per 100 vehicles, Audi is rated below average.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Acura vehicles are more reliable than Audi With 59 fewer problems per 100 vehicles in the first three years of ownership, J.D. 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.

Engine

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.

Fuel Economy and Range

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.

Transmission

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.

Brakes and Stopping

The RDX stops much shorter than the Q5:

	RDX	Q5
60 to 0 MPH	116 feet	136 feet	Motor Trend
60 to 0 MPH (Wet)	129 feet	144 feet	Consumer Reports

Tires and Wheels

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.

Suspension and Handling

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 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.

Chassis

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.

Passenger Space

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.

Cargo Capacity

The RDX has a much larger cargo volume with its rear seat up than the Q5 with its rear seat up (31.1 vs. 25.9 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. 54.1 cubic feet).

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Acura service is better than Audi. J.D. Power ranks Acura 9th in service department satisfaction (above the industry average). With a 16% lower rating, Audi is ranked 18th.

Ergonomics

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.

The RDX’s standard Smart Entry allow you to unlock the doors from either front door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless Start standard on the Q5 only offers hands-free access for the ignition, none to unlock the vehicle.

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.”

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Acura RDX has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Q5.

Economic Advantages

Insurance will cost less for the RDX owner. The Complete Car Cost Guide estimates that insurance for the RDX will cost $1630 to $4535 less than the Q5 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 Q5 only retains 49.06% to 52.87%.

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.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Acura RDX will be $4931 to $11687 less than for the Audi Q5.
