Compare the2025 Acura ADXVS 2025 Audi A4 Allroad

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 A4 Allroad 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 A4 Allroad doesn’t offer automatic braking for stationary objects directly to the rear.

The ADX has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the A4 Allroad’s blind spot costs extra.

To help make backing out of a parking space safer, the ADX has standard Rear Cross Traffic Monitor, helping the driver avoid collisions. Audi charges extra for Rear Cross-Traffic Assist on the A4 Allroad.

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 A4 Allroad doesn’t offer a driver alert monitor.

Both the ADX and the A4 Allroad have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear 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, rearview cameras, 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 A4 Allroad. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the A4 Allroad 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.

On the EPA test cycle the ADX gets better mileage than the A4 Allroad:

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 A4 Allroad 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 A4 Allroad doesn’t offer a CVT.

For better ride, handling and brake cooling the ADX A-Spec has standard 19-inch wheels. The A4 Allroad’s largest wheels are only 18-inches.

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 A4 Allroad doesn’t offer vehicle monitored tire inflation.

For better handling and stability, the track (width between the wheels) on the ADX is .5 inches wider in the front and 2.1 inches wider in the rear than on the A4 Allroad.

For better maneuverability, the ADX’s turning circle is 1.4 feet tighter than the A4 Allroad’s (37 feet vs. 38.4 feet).

For greater off-road capability the ADX has a greater minimum ground clearance than the A4 Allroad (7.3 vs. 6.5 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 250 to 500 pounds less than the Audi A4 Allroad.

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 A4 Allroad 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 A4 Allroad doesn’t offer active noise cancellation.

The ADX has 5.3 cubic feet more passenger volume than the A4 Allroad (97.3 vs. 92).

The ADX has 1 inch more front headroom, .6 inches more front legroom, .7 inches more front shoulder room, .6 inches more rear headroom, 2 inches more rear legroom and .7 inches more rear shoulder room than the A4 Allroad.

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’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 A4 Allroad doesn’t offer an easy entry system.

The ADX’s standard Keyless Access System 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. Keyless Engine Start/Stop standard on the A4 Allroad only offers hands-free access for the ignition, none to unlock the car.

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 A4 Allroad only has an intermittent setting, so in a hard rain visibility isn’t as good.

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. Only the A4 Allroad Premium Plus/Prestige offers wireless charging.

The ADX is available in both front-wheel drive and four-wheel drive configurations. The A4 Allroad doesn’t offer a two-wheel drive configuration.
