The 2020 Audi S7, with its 2.9L turbocharged V6 engine, gets an EPA-estimated 22 MPG combined. Although this isn’t hybrid-level fuel economy, it’s a reasonable trade-off for those wanting a strong performance sedan with a luxurious interior and refined handling. S7 buyers likely prioritize style and an engaging ride over ultimate fuel savings, and they still want practicality.

City and highway performance

The S7’s 2.9L V6 turbo, working with an eight-speed automatic transmission (S8), achieves 18 MPG in the city and 28 MPG on the highway. This difference shows the engine’s adaptability. City driving with its frequent stops greatly affects fuel consumption. On the highway, however, the S7’s well-tuned engine and efficient transmission allow for comfortable and economical cruising. The highway number is particularly good for a car with this much power, making the S7 a capable long-distance tourer.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Audi S7 at $2,650. This is calculated based on 15,000 miles of driving per year, with a 55/45 split between city and highway driving. This also assumes national average fuel prices at the time of calculation. Your actual fuel costs will vary based on how you drive, local fuel prices, and the type of gasoline you use. $2,650 gives you a good starting point for budgeting fuel expenses.

Real-world expectations

EPA ratings offer a standard comparison, but actual fuel economy varies. Driving hard, short trips, and cold weather all decrease MPG. Smooth acceleration, steady highway speeds, and gentle braking can help you match or beat the EPA estimates. The S7’s driving mode selector affects fuel usage as well. “Efficiency” mode emphasizes fuel savings by changing throttle response, shift points, and climate control. “Dynamic” mode enhances performance but reduces fuel economy.

How it compares

The BMW M550i xDrive, with its 4.4L V8, delivers similar performance, but typically gets around 20 MPG combined. The Mercedes-AMG E53 Sedan, which uses a mild-hybrid inline-6, achieves a slightly better 24 MPG combined, showing the advantages of a hybrid system. Even the Porsche Panamera 4S, while being a strong performer, gets around 21 MPG combined. For more information, review S7 MPG across all years. The S7 balances performance and fuel consumption, which appeals to buyers who want an exciting driving experience without terrible gas mileage. Comparing all Audi fuel economy data is also helpful.

Tips to maximize efficiency

Use the S7’s drive select modes. Sport or Dynamic mode is great for fun driving, but switch to Comfort or Efficiency for daily use. These modes can reduce fuel consumption by changing throttle response and shift patterns to prioritize economy.

Properly inflated tires reduce rolling resistance and improve fuel economy. Check the sticker on the driver’s side doorjamb for the correct pressure, and check your tires regularly.

Avoid idling. Modern engines are efficient at startup. If you’re stopped for more than a minute, turn off the engine to save fuel, especially in the city.

Gentle acceleration and braking will maximize fuel efficiency. Watch traffic and avoid hard acceleration or sudden stops. Smooth inputs will conserve fuel.

Weight is a major factor in fuel economy. Remove unnecessary items from the car, because a lighter car uses less gas.
