22 MPG combined is what you get for the 2023 Audi S7’s mix of performance and practicality. This isn’t a hybrid going for Prius-like efficiency; it’s a sleek, four-door coupe with substantial power and luxury, where fuel economy is less important than driving pleasure. S7 buyers aren’t prioritizing maximizing miles per gallon; they’re looking for an engaging driving experience with a good level of everyday usability.

City and highway performance

The EPA estimates the 2023 Audi S7 gets 19 MPG in the city and 26 MPG on the highway. The city rating shows how stop-and-go traffic reduces the benefits of the 2.9L turbocharged V6’s efficient design. However, the highway figure shows the powertrain’s ability to cruise efficiently at higher speeds. The 8-speed automatic transmission plays an important role, offering smooth shifts and optimized gear ratios for both acceleration and fuel conservation. Smart drivetrain management allows the engine to run at low RPMs when cruising, helping drivers get close to that 26 MPG target on long trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Audi S7 at $2,650. This is based on driving 15,000 miles per year, with a mix of city and highway driving, using national average fuel prices at the time of calculation. This is an estimate, and your actual fuel costs may vary depending on your driving habits, fuel prices in your area, and the type of fuel you use. This annual cost is a manageable expense within the overall ownership of a luxury performance vehicle like the S7. For drivers concerned about long-term running costs, comparing S7 MPG across all years could give valuable information.

Real-world expectations

The EPA provides a benchmark, but real-world fuel economy often varies. S7 drivers who accelerate quickly or mainly drive in the city will likely see figures below the combined 22 MPG rating. However, those who often take long highway trips and drive efficiently might get numbers closer to, or even slightly exceeding, the 26 MPG highway figure. The S7’s performance makes resisting the urge to use its power a factor in getting good fuel consumption.

How it compares

The Audi S7’s fuel economy is similar to other luxury performance sedans. For example, the Mercedes-AMG CLS 53, with its 3.0L inline-6 and mild-hybrid assist, gets a similar 21 MPG combined. The BMW M550i xDrive, with a more powerful V8, returns a slightly lower 20 MPG combined. The Porsche Panamera 4S, with its 2.9L V6, gets the same 22 MPG combined. The S7’s fuel economy is similar to its rivals, reflecting the trade-off between performance and efficiency in these vehicles. Buyers consider more than just MPG, but it’s important to understand all Audi fuel economy data before deciding on a specific model.

Tips to maximize efficiency

Use the Audi Drive Select system. Selecting the “Efficiency” mode optimizes vehicle settings, including throttle response and transmission mapping, to prioritize fuel conservation. This mode can noticeably reduce fuel consumption, especially during relaxed cruising.

Watch your driving habits and avoid aggressive acceleration and hard braking. The S7’s powerful engine is tempting to unleash, but doing so will significantly impact fuel economy. Smooth, consistent driving is how to get the best fuel efficiency.

Make sure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, leading to decreased fuel economy. Checking and maintaining proper tire pressure is a simple way to improve MPG.

Reduce unnecessary weight in the vehicle. Extra cargo increases the vehicle’s weight, forcing the engine to work harder and consume more fuel. Removing unnecessary items from the trunk and cabin can help improve efficiency.

Plan your routes to avoid stop-and-go traffic when possible. Idling in traffic consumes fuel without covering any distance. Opting for routes with smoother traffic flow or considering off-peak travel times can improve fuel economy.
