22 MPG combined is what you can expect from high-performance luxury sedans. It’s the fuel economy figure you accept when you want a twin-turbocharged V6, all-wheel drive, and the sleek design of the 2022 Audi S7. This isn’t a car bought for maximizing efficiency; it’s bought for making a statement and delivering effortless performance, and the mileage reflects that.

City and highway performance

The EPA estimates the 2022 Audi S7 will achieve 18 MPG in the city and 28 MPG on the highway. The city figure, while seemingly low on its own, is acceptable for a car with this much power and an all-wheel-drive system that adds weight and complexity. The highway figure is respectable, allowing for comfortable and relatively economical long-distance cruising, provided you accelerate modestly.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2022 Audi S7 is $2,650. This is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. The EPA also bases this estimate on national average fuel prices. Your actual fuel costs will vary depending on your driving habits, location, and the price of premium gasoline, which Audi recommends.

Real-world expectations

The EPA estimates provide a baseline, but real-world fuel economy for the 2022 Audi S7 can vary. Aggressive driving, frequent short trips, and prolonged idling will negatively impact fuel consumption. Gentle acceleration, consistent highway speeds, and using the car’s efficiency-focused driving modes can help you get figures closer to or even slightly exceeding the EPA estimates. Some drivers have seen highway MPG in the low 30s, especially on longer trips.

How it compares

The Audi S7 competes in a segment where fuel economy is often a secondary concern, but buyers still want to know how it stacks up against rivals. The BMW M550i xDrive, with its more potent V8, typically achieves around 17 MPG combined, showing that power requires more fuel. The Mercedes-AMG E53 sedan gets around 21 MPG combined. Even vehicles like the Porsche Panamera 4S, a direct competitor, get similar MPG figures, showing how the S7 fits into the segment. For those prioritizing fuel economy, exploring all Audi fuel economy data might reveal more efficient options.

Tips to maximize efficiency

Use the Audi Drive Select system. Try the different driving modes, particularly “Efficiency” or “Comfort” mode, which optimizes engine and transmission settings for fuel economy. Using these modes regularly can improve your MPG, especially during daily driving.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check your tire pressure regularly, using the sticker on the driver’s side doorjamb as a guide, and adjust as needed.

Anticipate traffic and drive smoothly. Avoid sudden acceleration and hard braking, as these actions waste fuel. By anticipating traffic flow and maintaining a consistent speed, you can minimize unnecessary fuel consumption and maximize efficiency. Activate adaptive cruise control on the highway to smooth out acceleration.

Reduce idling. Idling consumes fuel without moving the car. If you expect to be stopped for more than a minute or two, turn off the engine. The S7’s automatic start/stop system can help in city driving, though it can be disabled. Looking at the S7 MPG across all years, newer models often have features for better economy.

Reduce weight. Remove any unnecessary items from your car, as extra weight reduces fuel economy. Don’t use your S7 for storage. A lighter car is more efficient.
