22 MPG combined won’t win any hypermiling awards, but it’s a figure most 2024 Audi S6 owners will accept as the price for its performance, luxury, and understated style. This isn’t a car bought by penny-pinchers; it’s a statement of power, and the fuel bill, while not insignificant, is part of owning it.

City and highway performance

The EPA estimates 19 MPG in the city and 26 MPG on the highway for the 2024 Audi S6 with its 2.9L V6. The city figure reflects the engine’s need to repeatedly accelerate the S6’s mass from stoplights and navigate congested traffic. The highway number is more appealing, as the engine settles into a more efficient cruising speed. Factors like driving style, traffic conditions, and ambient temperature will influence these figures. Expect to see a dip in MPG during spirited acceleration or while battling headwinds on long road trips.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2024 Audi S6 is $2,650. This figure is based on driving 15,000 miles per year and using the EPA’s estimate of combined MPG, assuming current national average fuel prices, which fluctuate. It’s a useful benchmark, but remember that premium fuel is required for the S6 to achieve optimal performance and efficiency. Your actual fuel costs might be higher or lower depending on your driving habits and local fuel prices. It’s important to consider this cost when budgeting for the total cost of ownership, including insurance, maintenance, and potential repairs.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often varies. S6 drivers who frequently engage the car’s sport modes or spend a significant amount of time in stop-and-go traffic will likely see MPG figures at the lower end of the EPA’s range. Consistent highway driving, combined with a measured approach to the throttle, could yield results closer to, or even slightly above, the 26 MPG highway estimate. Ambient temperature affects fuel economy, so your winter gas mileage will typically be lower than in warmer months.

How it compares

The Audi S6 is in a competitive segment where fuel economy isn’t always the primary focus. The BMW M550i xDrive, another high-performance sedan with all-wheel drive, achieves 20 MPG combined. The Mercedes-AMG E53 Sedan, with its mild-hybrid system, manages 24 MPG combined. And the Cadillac CT5-V, with its turbocharged V6, comes in at around 21 MPG combined. These figures highlight that the S6’s fuel economy is within the expected range for its class; none of these cars are particularly frugal. However, even a slight difference in MPG can translate to hundreds of dollars saved (or spent) at the pump each year, influencing the ownership cost for some buyers.

Tips to maximize efficiency

Use a light foot on the accelerator. The S6’s turbocharged engine delivers ample power, but aggressive acceleration burns fuel quickly. Smooth, gradual inputs will help optimize efficiency, especially around town. See S6 MPG across all years; these strategies have been effective in the past.

Consider using Audi’s “Efficiency” drive mode when conditions allow. This mode optimizes various vehicle systems, including the transmission and throttle response, to prioritize fuel savings. This mode may make long highway cruises a bit boring, but you’ll be at the pump less often.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly and inflate them to the recommended levels. This is a simple maintenance task that can make a noticeable difference. You can consult all Audi fuel economy data to see how properly maintaining your vehicle can really have an effect!

Minimize idling. Modern engines, including the S6’s V6, are more efficient when running than when idling. If you anticipate being stopped for more than a minute or two, consider turning off the engine, where appropriate.
