J.D. Power and Associates’ 2022 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 4 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Infiniti higher than Audi.

The QX55’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.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Infiniti QX55 higher (6 out of 10) than the Audi A4 Allroad (5). This means the QX55 produces up to 6.9 pounds less smog-producing pollutants than the A4 Allroad every 15,000 miles.

The QX55 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 QX55 has larger tires than the A4 Allroad (255/45R20 vs. 245/45R18).

For better ride, handling and brake cooling the QX55 has standard 20-inch wheels. Only 18-inch wheels are available on the A4 Allroad.

The QX55 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 QX55 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 track (width between the wheels) on the QX55 is 2.3 inches wider in the front and 2.1 inches wider in the rear than on the A4 Allroad.

For better maneuverability, the QX55’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 QX55 has a 2.1 inches greater minimum ground clearance than the A4 Allroad (8.6 vs. 6.5 inches), allowing the QX55 to travel over rougher terrain without being stopped or damaged.

To almost totally eliminate engine vibration in the passenger area, the QX55 has an electronically controlled liquid-filled main 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 QX55 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 QX55 has 8.2 cubic feet more passenger volume than the A4 Allroad (100.2 vs. 92).

The QX55 has 2.5 inches more front headroom, 2 inches more front shoulder room, 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 QX55’s rear seats recline. The A4 Allroad’s rear seats don’t recline.

The QX55 has a much larger cargo volume than the A4 Allroad with its rear seat up (26.9 vs. 24.2 cubic feet).

The QX55’s standard Entry/Exit Assist raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The A4 Allroad doesn’t offer an easy entry system.

To improve rear visibility by keeping the rear window clear, the QX55 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.

The A4 Allroad’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The QX55 Essential/Sensory’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Infiniti QX55 has a standard wireless phone charging system (Qi) in the center console. Only the A4 Allroad Premium Plus/Prestige offers wireless charging.
