Compare the2025 Acura ADXVS 2025 Audi Q3

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 ADX are reminded to check the back seat if they opened the rear door before starting out. The Q3 doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The ADX A-Spec offers an optional Low-Speed Braking Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Q3 doesn’t offer automatic braking for stationary objects directly to the rear.

The ADX’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Q3 doesn’t offer a driver alert monitor.

Both the ADX and the Q3 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee 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.

Acura’s powertrain warranty covers the ADX 2 years and 20,000 miles longer than Audi covers the Q3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Q3 ends after only 4 years or 50,000 miles.

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’ March 2025 Auto Issue reports that Acura vehicles are more reliable than Audi vehicles. Consumer Reports ranks Acura 2 places higher in reliability than Audi.

The ADX’s 1.5 turbo 4-cylinder produces 6 more horsepower (190 vs. 184) than the Q3 40 TFSI’s standard 2.0 turbo 4-cylinder.

On the EPA test cycle the ADX gets better mileage than the Q3:

The ADX 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 Q3 doesn’t offer a cap-less fueling system.

The ADX has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Q3 doesn’t offer a CVT.

The ADX 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 Q3 doesn’t offer vehicle monitored tire inflation.

For better handling and stability, the track (width between the wheels) on the ADX is .4 inches wider in the front and 1.3 inches wider in the rear than on the Q3.

For better maneuverability, the ADX’s turning circle is 1.7 feet tighter than the Q3’s (37 feet vs. 38.7 feet).

For greater off-road capability the ADX has a 1.8 inches greater minimum ground clearance than the Q3 (7.3 vs. 5.5 inches), allowing the ADX to travel over rougher terrain without being stopped or damaged.

The Acura ADX may be more efficient, handle and accelerate better because it weighs about 300 to 550 pounds less than the Audi Q3.

The front grille of the ADX uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Q3 doesn’t offer active grille shutters.

The ADX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Q3 doesn’t offer active noise cancellation.

The ADX has 13.3 cubic feet more passenger volume than the Q3 (97.3 vs. 84).

The ADX has 1.9 inches more front legroom, .4 inches more rear headroom, 1.6 inches more rear legroom and .1 inches more rear shoulder room than the Q3.

The ADX has a larger cargo volume with its rear seat up than the Q3 with its rear seat up (24.4 vs. 23.7 cubic feet). The ADX has a larger cargo volume with its rear seat folded than the Q3 with its rear seat folded (55.1 vs. 48 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 15% lower rating, Audi is ranked 18th.

The ADX A-Spec 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 Q3 doesn’t offer a remote starting system.

The ADX A-Spec’s optional easy exit feature glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Q3 doesn’t offer an easy entry system.

The ADX has a standard Keyless Access System that allows 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. The Audi Advanced Key costs extra on the Q3.

The ADX’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 Q3’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 ADX has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Q3 only has an intermittent setting, so in a hard rain visibility isn’t as good.

When the ADX is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Q3’s mirror doesn’t automatically adjust for backing.

Standard air-conditioned seats in the ADX A-Spec keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Q3 doesn’t offer air-conditioned seats.

On extremely cold winter days, the ADX A-Spec’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The Q3 doesn’t offer a heated steering wheel.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Acura ADX has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Q3.

The ADX is available in both front-wheel drive and four-wheel drive configurations. The Q3 doesn’t offer a two-wheel drive configuration.
