Compare the2025 Infiniti QX50VS 2024 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 QX50 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 QX50 has standard Rear Automatic Braking 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 QX50 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 and moves the vehicle back into its lane. 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 QX50 has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Audi charges extra for Rear Cross-Traffic Assist on the A4 Allroad.

Both the QX50 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, plastic fuel tanks, 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, rearview cameras 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 Infiniti QX50 is safer than the Audi A4 Allroad:

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

The QX50 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The A4 Allroad’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

Infiniti’s powertrain warranty covers the QX50 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.

Infiniti pays for scheduled maintenance on the QX50 for 3 years and 22500 miles. Infiniti will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the A4 Allroad.

To reliably start during all conditions and help handle large electrical loads, the QX50 has a standard 720-amp battery. The A4 Allroad’s 420-amp battery isn’t as powerful.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Infiniti above average in initial quality. With 55 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 Infiniti vehicles are more reliable than Audi With 56 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Infiniti higher than Audi.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Infiniti vehicles are more reliable than Audi vehicles. Consumer Reports ranks Infiniti 6 places higher in reliability than Audi.

The QX50’s 2.0 turbo 4-cylinder produces 7 more horsepower (268 vs. 261) and 7 lbs.-ft. more torque (280 vs. 273) than the A4 Allroad’s 2.0 turbo 4-cylinder hybrid.

The QX50 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 traction, the QX50 Sport’s tires are larger than the largest tires available on the A4 Allroad (255/45R20 vs. 245/45R18).

For better ride, handling and brake cooling the QX50 has standard 19-inch wheels. Only 18-inch wheels are available on the A4 Allroad. The QX50 Sport has standard 20-inch wheels.

The QX50 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.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX50 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The A4 Allroad doesn’t offer run-flat tires.

For better handling and stability, the average track (width between the wheels) on the QX50 is 2.3 inches wider in the front and 2.3 inches wider in the rear than the track on the A4 Allroad.

The QX50 handles at .84 G’s, while the A4 Allroad Premium Plus pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the QX50’s turning circle is 2 feet tighter than the A4 Allroad’s (36.4 feet vs. 38.4 feet).

For greater off-road capability the QX50 has a 2.1 inches greater minimum ground clearance than the A4 Allroad (8.6 vs. 6.5 inches), allowing the QX50 to travel over rougher terrain without being stopped or damaged.

To almost totally eliminate engine vibration in the passenger area, the QX50 has an electronically controlled liquid-filled front engine mount. A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The A4 Allroad uses conventional solid rubber engine mounts.

The design of the Infiniti QX50 amounts to more than styling. The QX50 has an aerodynamic coefficient of drag of .32 Cd. That is lower than the A4 Allroad (.34) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the QX50 get better fuel mileage.

The QX50 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 QX50 has 12.4 cubic feet more passenger volume than the A4 Allroad (104.4 vs. 92).

The QX50 has 3.6 inches more front headroom, 2 inches more front shoulder room, 1.7 inches more rear headroom, 3 inches more rear legroom and 2.6 inches more rear shoulder room than the A4 Allroad.

For enhanced passenger comfort on long trips the QX50’s rear seats recline. The A4 Allroad’s rear seats don’t recline.

The QX50 has a much larger cargo volume with its rear seat up than the A4 Allroad with its rear seat up (31.4 vs. 24.2 cubic feet). The QX50 has a much larger cargo volume with its rear seat folded than the A4 Allroad with its rear seat folded (65.1 vs. 58.5 cubic feet).

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Audi. J.D. Power ranks Infiniti 6th in service department satisfaction (above the industry average). With a 28% lower rating, Audi is ranked 18th.

The QX50 Luxe/Sport’s standard Entry/Exit Assist raises the steering wheel and 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 QX50’s standard Infiniti Intelligent Key allow you to unlock the doors from any outside 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 QX50 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 Infiniti QX50 has a standard wireless phone charging system (Qi) in the center console. Only the A4 Allroad Premium Plus/Prestige offers wireless charging.
