The EPA estimates 22 MPG combined for the 2020 Audi A6 Allroad. While it won’t win any hypermiling contests, it’s an acceptable number for a supremely comfortable, technologically advanced, and genuinely capable all-weather wagon. The A6 Allroad isn’t usually purchased by those obsessed with maximizing every last drop of fuel. It’s bought by individuals who appreciate a refined driving experience, ample cargo space, Audi’s Quattro all-wheel-drive system, and understated elegance. They likely accept the fuel economy as the price of admission for the Allroad’s unique blend of traits.

City and highway performance

The 2020 A6 Allroad achieves 20 MPG in the city and 26 MPG on the highway, according to EPA estimates. The city figure reflects the demands placed on the 3.0-liter turbocharged V6 engine and seven-speed S tronic dual-clutch automatic transmission during stop-and-go traffic. The highway number demonstrates the engine’s ability to cruise efficiently on long journeys. The 3.0L V6 includes a mild-hybrid system which improves fuel economy a small amount.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Audi A6 Allroad at $2,650. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, local fuel prices, and how often you drive the Allroad hard. You can view all Audi fuel economy data on FuelEconomyHub.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often deviates. Factors such as aggressive driving, carrying heavy loads, and driving in extreme weather conditions can all negatively impact fuel efficiency. Conversely, gentle acceleration, consistent highway speeds, and proper tire inflation can help drivers achieve figures closer to (or even slightly better than) the EPA estimates. Many owners report figures that are in line with the EPA’s combined 22 MPG rating, particularly on longer trips.

How it compares

Compared to other luxury wagons, the A6 Allroad’s fuel economy is competitive. The Volvo V90 Cross Country, another popular choice in this segment, achieves an EPA-estimated 22 MPG combined mirroring the Allroad. However, other AWD SUVs, such as the BMW X5 xDrive40i (23 MPG combined), offer slightly better fuel economy, though they trade the wagon’s aesthetics and driving dynamics for a taller ride height and more SUV-like character. The Porsche Macan S, a performance-oriented SUV, achieves 19 MPG combined. For this buyer, the comparison matters less about outright savings and more about understanding the trade-offs between different vehicle types and their attributes. It also informs those considering the A6 MPG across all years.

Tips to maximize efficiency

Use the Audi Drive Select system to optimize fuel economy. Selecting “Efficiency” mode will adjust the engine, transmission, and climate control settings to prioritize fuel efficiency. This mode reduces throttle response and encourages earlier upshifts.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the door jamb sticker.

Avoid aggressive driving habits. Rapid acceleration and hard braking consume significantly more fuel. Smooth and gradual acceleration, along with anticipating traffic flow, not only improves fuel economy but also enhances the overall driving experience.

Reduce unnecessary weight. Remove any items from the vehicle that are not essential. Excess weight places additional strain on the engine, contributing to lower fuel economy. Clear out that golf set if you aren’t heading to the course.

Consider shorter trips in a more efficient vehicle. If you have another vehicle with better fuel economy in your household, use it for short trips around town. This will reduce the overall fuel consumption of the Allroad, particularly in stop-and-go traffic where its efficiency is at its lowest.
