Compare the2023 Acura RDXVS 2023 Audi Q4 e-tron

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 Q4 e-tron doesn’t offer knee airbags.

Both the RDX and the Q4 e-tron 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.

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 Q4 e-tron has not been fully tested, yet.

Acura’s powertrain warranty covers the RDX 2 years and 20,000 miles longer than Audi covers the Q4 e-tron. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Q4 e-tron 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 Q4 e-tron.

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 32 points higher than the Q4 e-tron.

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 51 lbs.-ft. more torque (280 vs. 229) than the Q4 40 e-tron’s standard electric motor.

The Acura RDX has standard four-wheel disc brakes for better stopping power and improved directional control in poor weather. Only rear drums come on the Q4 e-tron. Drums can heat up and make stops longer, especially with antilock brakes that work much harder than conventional brakes.

The RDX stops shorter than the Q4 e-tron:

For better traction, the RDX A-Spec’s tires are larger than the largest tires available on the Q4 e-tron (255/45R20 vs. 235/55R19).

The RDX A-Spec’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Q4 e-tron Quattro’s optional 50 series front tires.

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 Q4 e-tron doesn’t offer vehicle monitored tire inflation.

The RDX AWD has a standard space-saver spare (not available on FWD/A-Spec) so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Q4 e-tron; it requires you to depend on roadside assistance and your vehicle will have to be towed.

For better handling and stability, the track (width between the wheels) on the RDX is 1.9 inches wider in the front and 3.2 inches wider in the rear than on the Q4 e-tron.

The Acura RDX may be more efficient, handle and accelerate better because it weighs about 800 to 900 pounds less than the Audi Q4 e-tron.

The RDX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Q4 e-tron doesn’t offer active noise cancellation.

The RDX has 1.1 inches more front headroom, .4 inches more front legroom, 3 inches more front shoulder room, 1.2 inches more rear legroom and 1.5 inches more rear shoulder room than the Q4 e-tron.

The RDX has a much larger cargo volume with its rear seat up than the Q4 e-tron with its rear seat up (31.1 vs. 24.8 cubic feet). The RDX has a much larger cargo volume with its rear seat folded than the Q4 e-tron with its rear seat folded (79.8 vs. 53.1 cubic feet).

The RDX uses gas struts to support the hood for easier service access. The Q4 e-tron uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

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’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Q4 e-tron’s cruise control switches are unlit, making them difficult to find at night and operate safely.

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 Q4 e-tron only has an intermittent setting, so in a hard rain visibility isn’t as good.

Both the RDX and the Q4 e-tron have standard heated front seats. The RDX Advance also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Q4 e-tron.

Standard air-conditioned seats in the RDX A-Spec/Advance keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Q4 e-tron doesn’t offer air-conditioned seats.

Insurance will cost less for the RDX owner. The Complete Car Cost Guide estimates that insurance for the RDX will cost $2655 to $4530 less than the Q4 e-tron 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 47.35% to 49.21% of its original price after five years, while the Q4 e-tron only retains 44.62% to 46.17%.
