The 2025 Audi S7, with its 22 MPG combined, is a performance-oriented luxury sedan that takes fuel consumption into consideration. Buyers probably aren’t expecting Prius-like efficiency, but also don’t want to spend too much on gas. The S7 is a good middle ground, with engaging performance and attractive styling, plus acceptable fuel efficiency.

City and highway performance

The S7’s 19 MPG city rating reflects typical stop-and-go driving conditions. The 2.9L twin-turbo V6 uses more fuel when accelerating from a stop. This number will likely drop in congested city environments with lots of idling. The S7 performs better on the highway. Its 27 MPG highway figure shows the engine can achieve good efficiency when cruising at consistent speeds. Careful throttle control and anticipating traffic can help you get close to this number, but aerodynamic drag and engine size will limit how high it can go.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Audi S7 at $2,650. This assumes 15,000 miles of driving per year, with 55% in the city and 45% on the highway, using national average fuel prices. Premium gasoline is required for best performance and fuel economy, which will affect your fuel budget. Your actual costs will vary depending on driving habits, local fuel prices, and how much you drive in the city versus on the highway. Expect to spend more than $2,650 if you mostly drive in the city or have a heavy foot.

Real-world expectations

The numbers will change based on how you drive. Fast acceleration, using Sport mode often, carrying extra weight, and bad weather will all hurt your fuel economy. Driving smoothly, keeping tires properly inflated, and minimizing use of accessories like air conditioning can help you get closer to the EPA estimates. Drivers will probably see numbers closer to the low end of the range. The EPA figures are an optimistic view.

How it compares

The S7’s fuel economy is competitive within the performance sedan category, but not class-leading. The Mercedes-AMG CLS53, with its mild-hybrid inline-6, gets slightly better combined fuel economy, around 24 MPG. The BMW M550i xDrive, with a larger V8, is closer to the S7, around 20 MPG combined. Porsche’s Panamera 4S, with its twin-turbo V6, has similar numbers to the S7. These comparisons are important for buyers who are balancing performance with fuel costs. A more efficient competitor might have less horsepower or worse handling.

Tips to Maximize Efficiency

Anticipate traffic to reduce unnecessary braking and acceleration. Keeping a steady speed, especially on the highway, greatly reduces fuel use. The S7’s strong brakes may hide the wasted energy from braking, but the car needs more fuel to accelerate again.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Check your owner’s manual for the recommended tire pressure. Tire pressure changes with temperature, so check them often to maximize efficiency.

Avoid using the S7’s full power all the time. The twin-turbo V6 is fun, but frequent full-throttle acceleration will greatly reduce fuel economy. Drive more smoothly when fuel efficiency is a priority. Sport mode is best for the track.

Reduce use of accessories like air conditioning and heated seats. These put extra load on the engine, using more fuel. Use them carefully, and choose lower settings when possible. If weather allows, open the windows instead of using the AC.
