The 2022 Audi A6 Allroad quattro achieves 23 MPG combined, which requires some context. It’s not a compact hatchback but a luxury wagon designed for reliable performance in all weather, comfortable long trips, and light off-road driving. Buyers tend to value capability and exclusivity more than extreme fuel efficiency, understanding that the turbocharged V6 engine and quattro all-wheel-drive system affect fuel consumption.

City and highway performance

The EPA estimates the A6 Allroad gets 21 MPG in the city and 28 MPG on the highway. The city MPG reflects frequent stops and starts and acceleration, conditions where the turbocharger boosts more often. The highway MPG shows the benefits of the A6 Allroad’s aerodynamic design and the efficiency of its seven-speed automatic transmission (AM-S7) at constant speeds. This difference suggests the Allroad is better suited for drivers who spend considerable time on the highway, where fuel efficiency can approach or exceed the EPA estimate.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Audi A6 Allroad at $2,500, based on driving 15,000 miles per year and national average fuel prices. Actual fuel costs will vary based on driving habits, local fuel prices, and the grade of gasoline used. Audi recommends premium fuel for the best performance, which typically costs more than regular. While $2,500 might seem high compared to more fuel-efficient vehicles, A6 Allroad buyers are typically less concerned about fuel costs than shoppers considering a mainstream sedan or budget SUV.

Real-world expectations

The EPA provides a standard estimate, but the A6 Allroad’s real-world fuel economy can change. Aggressive driving, frequent short trips, heavy loads, and using air conditioning can all decrease MPG. Gentle acceleration, consistent highway speeds, and proper tire inflation can improve fuel efficiency.

Many owners report achieving numbers close to the EPA estimates, especially on longer trips. Others may see lower numbers based on their driving style and typical usage. Checking A6 MPG across all years can provide more evidence from owners. The Allroad’s fuel efficiency depends on various factors.

How it compares

The A6 Allroad is in a niche segment where fuel economy isn’t the biggest factor. The Volvo V90 Cross Country, another lifted wagon with standard all-wheel drive, gets around 25 MPG combined with its turbocharged and supercharged four-cylinder engine. The Mercedes-Benz E450 All-Terrain, a direct competitor, delivers similar fuel economy to the Audi with its turbocharged inline-six. A BMW X5 xDrive40i SUV gets around 23 MPG combined as well.

The Allroad’s fuel consumption is close to others in its class. These comparisons are helpful for buyers who want a capable luxury vehicle without losing too much efficiency. Comparing all Audi fuel economy data can also be helpful.

Tips to maximize efficiency

Use the Audi Drive Select system to improve fuel economy. The “Efficiency” mode changes the engine and transmission settings to prioritize fuel savings. This results in less aggressive acceleration and earlier upshifts, which can help, especially in city driving.

Check your tire pressure regularly. Underinflated tires increase rolling resistance, which makes the engine work harder and consumes more fuel. The A6 Allroad’s tire pressure monitoring system (TPMS) will alert you to low pressure, but manual checks are recommended.

Avoid unnecessary idling. Modern engines are designed to be efficient when running, but idling uses fuel without moving the car. If you’re stopped for over a minute, like at a long light, turning off the engine is more efficient.

Reduce the weight. Carrying extra weight in the vehicle reduces fuel economy. Remove any non-essential items from the trunk or cargo area, as even small amounts of weight can affect efficiency.
