In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Infiniti QX55 higher (6 out of 10) than the Audi A6 Allroad (5). This means the QX55 produces up to 6.9 pounds less smog-producing pollutants than the A6 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 A6 Allroad doesn’t offer a CVT.

For better traction, the QX55 has larger tires than the A6 Allroad (255/45R20 vs. 245/45R20).

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 A6 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 A6 Allroad doesn’t offer run-flat tires.

The QX55 Essential handles at .87 G’s, while the A6 Allroad Prestige pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the QX55’s turning circle is 3.6 feet tighter than the A6 Allroad’s (36.4 feet vs. 40 feet).

For greater off-road capability the QX55 has a 2.5 inches greater minimum ground clearance than the A6 Allroad Premium Plus (8.6 vs. 6.1 inches), allowing the QX55 to travel over rougher terrain without being stopped or damaged. The QX55’s minimum ground clearance is 1.3 inches higher than on the A6 Allroad Prestige (8.6 vs. 7.3 inches).

The Infiniti QX55 may be more efficient, handle and accelerate better because it weighs about 350 to 400 pounds less than the Audi A6 Allroad.

The QX55 has 1.6 inches more front headroom, .1 inches more front shoulder room, 1.3 inches more rear legroom and .6 inches more rear shoulder room than the A6 Allroad.

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 QX55’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 A6 Allroad’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 QX55 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the A6 Allroad only has an intermittent setting, so in a hard rain visibility isn’t as good.
