24 MPG combined isn’t going to win any hypermiling competitions, but it’s an understandable compromise for the 2022 Audi S4. This isn’t a fuel-sipping commuter car; it’s a performance sedan dressed in a tailored suit, designed for drivers who appreciate a responsive engine and sharp handling. Those buyers prioritize driving enjoyment over outright fuel efficiency, accepting mid-pack numbers as the cost.

City and highway performance

The EPA estimates the 2022 Audi S4 at 21 MPG in the city and 30 MPG on the highway. The city figure reflects the stop-and-go reality of urban driving, where the S4’s 3.0L turbocharged V6 is constantly accelerating and decelerating. The highway number shows the engine’s efficiency when cruising at a steady speed. These figures are achieved using the standard eight-speed automatic transmission (S8), which is tuned for both performance and fuel economy. The spread between city and highway suggests that drivers who spend more time on open roads will see better overall economy than those primarily driving in urban environments.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Audi S4 at $2,400. This figure is based on driving 15,000 miles per year and using national average fuel prices. The S4 requires premium fuel, which costs more per gallon, directly influencing this annual cost. Individual expenses will vary depending on location, driving habits, and current fuel prices, but $2,400 serves as a reasonable benchmark for budgeting.

Real-world expectations

While the EPA provides a standardized test, real-world fuel economy can vary significantly. Aggressive driving, frequent short trips, and even weather conditions can impact the S4’s fuel efficiency. Drivers with a lead foot will likely see numbers below the EPA estimates, while those with a more conservative driving style might achieve slightly better results. Consider the EPA estimates a baseline, and adjust your expectations based on your individual driving patterns and conditions. Checking S4 MPG across all years user reviews and forums for anecdotal data is also a useful practice.

How it compares

The Audi S4 occupies an interesting space in the performance sedan market. The BMW M340i, a direct competitor, achieves a slightly better combined MPG of 25, thanks to its own turbocharged inline-six. The Mercedes-AMG C43, another rival, closely mirrors the S4 with its own turbocharged V6 and nearly identical fuel economy estimates. An Acura TLX Type S, another option, offers comparable performance with a 21 MPG combined rating. The S4’s numbers reflect its positioning in this performance segment: not the most efficient, but also not the least. Buyers in this segment recognize that performance requires a trade-off, and often find the S4’s blend of power, luxury, and acceptable gas mileage suitable. Those interested in seeing all Audi fuel economy data can compare models across the entire brand lineup.

Tips to maximize efficiency

Gentle acceleration is key. The S4’s turbocharged engine delivers ample power, but using it carefully will significantly improve fuel economy. Avoid aggressive starts and heavy braking, especially in city driving. Smooth, consistent throttle inputs are more efficient than abrupt bursts of power.

Monitor tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Check your tire pressure at least once a month and ensure it matches the recommended pressure listed on the driver’s side door jamb.

Use the Audi Drive Select system wisely. The S4 offers different driving modes that adjust various vehicle parameters, including throttle response and transmission mapping. Selecting the “Efficiency” mode optimizes the car for fuel economy by prioritizing early upshifts and reducing throttle sensitivity. While sacrificing some responsiveness, this mode can noticeably improve gas mileage in everyday driving.

Minimize unnecessary weight. Carrying excessive cargo in the trunk or backseat adds weight, which requires more energy to accelerate and maintain speed. Remove any unnecessary items from the vehicle to improve fuel efficiency.

Plan your trips strategically. Combining errands into a single trip reduces cold starts, which use a lot of fuel. Avoiding peak traffic times can also minimize stop-and-go driving, further improving fuel economy. Smart route planning can have a surprisingly large impact on your overall gas mileage.
