24 MPG combined is what you get for a premium wagon that handles bad weather and has good cargo capacity. The 2023 Audi A6 Allroad isn’t about maximizing fuel efficiency, it’s about blending practical capability with luxurious comfort, and doing so with a distinctive style that SUVs simply can’t match. People who buy this vehicle want a confident driving experience in all conditions, and understand that comes with certain compromises at the pump. They accept the A6 Allroad’s fuel consumption because it’s part of the vehicle’s appeal.

City and highway performance

The EPA estimates the A6 Allroad gets 21 MPG in the city and 30 MPG on the highway. These figures show the balance Audi wanted between performance and fuel economy. The turbocharged 3.0-liter six-cylinder engine, paired with a seven-speed automatic transmission, provides plenty of power for confident acceleration and easy cruising. City driving, with its stop-and-go nature, predictably reduces efficiency. However, the highway figure is respectable for a vehicle of this size and capability. The Allroad’s Quattro all-wheel-drive system, a standard feature, ensures secure handling in all weather conditions but also lowers fuel economy compared to front-wheel-drive rivals. Remember that aggressive driving, even on the highway, will reduce observed MPG. People who often travel at higher speeds should lower their expectations, as the aerodynamic drag on a wagon body increases a lot over 70 mph.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2023 Audi A6 Allroad is $2,400. This figure is based on driving 15,000 miles per year and using national average fuel prices. Individual fuel costs will vary depending on driving habits and local fuel prices, but this gives a good benchmark for prospective owners. This is an estimate, drivers who mostly drive highway miles will likely spend less, while those who often drive in congested city streets and accelerate more aggressively will likely spend more. The calculation also assumes using the recommended fuel type, which may impact both performance and economy if you use something else. Always check the owner’s manual for specific fuel recommendations.

Real-world expectations

EPA estimates offer a useful baseline, but real-world fuel economy often differs. Some A6 Allroad owners report figures slightly below the EPA combined rating, especially in areas with hills or frequent heavy traffic. Tire pressure, vehicle load, and even using accessories like roof racks can change fuel consumption. The Allroad’s air suspension enhances ride quality and off-pavement capability, adds weight, which affects efficiency. Drivers who accelerate smoothly and anticipate traffic conditions can often get closer to the EPA estimates. The temptation to use the Allroad’s responsive engine can easily lead to lower MPG figures, though.

How it compares

The A6 Allroad’s fuel economy is average compared to other luxury wagons and SUVs. The Volvo V90 Cross Country, another wagon, gets a similar 25 MPG combined in its B6 AWD configuration, so they’re very similar. The Mercedes-Benz E450 All-Terrain wagon gets a slightly less impressive 23 MPG combined, also close to the A6. Switching to an SUV shows a similar story, the BMW X5 xDrive40i is rated at 23 MPG combined. The Allroad’s fuel economy is standard for a luxury vehicle with its capabilities. For buyers considering the A6, checking all Audi fuel economy data may be helpful. Researching A6 MPG across all years could also be useful if you only want to know about the A6.

Tips to maximize efficiency

Pay attention to tire pressure. The A6 Allroad’s air suspension provides a comfortable ride, but correct tire pressure is critical for safety and fuel economy. Regularly check and inflate tires to the recommended pressure listed on the door jamb sticker. Underinflated tires increase rolling resistance, lowering MPG and causing tires to wear out faster.

Anticipate traffic flow. The Allroad’s responsive engine makes you want to drive fast, but quick acceleration and hard braking reduce fuel efficiency. Look ahead, see traffic signals, and maintain a steady pace when you can. Smooth, gradual acceleration is more efficient than aggressive bursts of power.

Minimize idling time. Idling uses fuel without going anywhere. If you’ll be stopped for more than a minute, like waiting in a parking lot, turn off the engine. The A6 Allroad’s engine start-stop system helps with idling fuel consumption, but turning off the engine manually in long stops can still help.

Reduce excess weight. Extra cargo adds weight, which impacts fuel economy. Remove items from the cargo area that you don’t need. A lighter vehicle needs less energy to accelerate and maintain speed, leading to better MPG.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, reducing unnecessary acceleration and deceleration. This helps on long highway drives, where speed changes can noticeably impact fuel consumption. Remember road conditions and traffic, disengage cruise control if needed for safety.
