24 MPG combined is the fuel economy for the 2024 Audi S4. Nobody buys an S4 solely for its gas mileage. They buy it for the responsive 3.0L turbocharged V6, the standard Quattro all-wheel drive, and the understated performance that allows it to blend in while possessing surprising capabilities. An S4 buyer accepts its fuel consumption as the price of entry for a comfortable and capable sports sedan, not as a primary purchase driver.

City and highway performance

The EPA estimates the 2024 Audi S4 will achieve 21 MPG in the city and 29 MPG on the highway. These numbers reflect the performance characteristics of the turbocharged six-cylinder engine and the eight-speed automatic transmission. The city figure is respectable given the engine’s power output. The highway number suggests that extended road trips can be undertaken without excessive fuel stops. The relatively wide gap between city and highway figures highlights the S4’s efficiency at steady speeds versus the demands of stop-and-go driving.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2024 Audi S4 is exactly $2,400. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Of course, individual driving habits and local fuel prices can significantly impact the actual amount spent on gasoline. Heavy-footed drivers in areas with high fuel costs should anticipate spending considerably more, while those with shorter commutes and more highway driving may see lower annual fuel expenses.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often varies. Aggressive driving, frequent short trips, and extreme weather conditions can all lower fuel economy. Gentle acceleration, consistent highway speeds, and meticulous maintenance can improve it. Drivers should use the EPA numbers as a baseline. Then, adjust their expectations based on their personal driving style and conditions. Many owners find that matching the EPA’s combined figure is achievable with mindful driving habits.

How it compares

The S4’s fuel economy positions it in a specific segment of the performance sedan market. A BMW M340i xDrive, a direct competitor, achieves a slightly better 26 MPG combined. The Genesis G70 3.3T, another compelling alternative, comes in a bit lower at 20 MPG combined. Checking S4 MPG across all years can provide further context. These differences, while seemingly small on paper, can translate to hundreds of dollars in annual fuel costs. These cars all deliver sporty driving experiences, so buyers often weigh performance against fuel efficiency. The S4’s slightly lower MPG is a compromise some are willing to make for its distinctive blend of luxury, understated styling, and all-weather capability.

Tips to maximize efficiency

Take advantage of the Audi Drive Select system. Selecting the “Efficiency” mode alters the engine and transmission settings to prioritize fuel conservation. This mode typically softens throttle response and encourages earlier upshifts, reducing fuel consumption without hindering performance.

Regularly check and maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure, and check it at least once a month.

Minimize idling time. Letting the engine idle for extended periods wastes fuel unnecessarily. If you anticipate waiting for more than a minute, turn off the engine. Modern engines do not require long warm-up periods, so idling is generally unproductive.

Avoid aggressive acceleration and braking. Rapid acceleration and hard braking consume significantly more fuel than smooth, gradual inputs. Anticipate traffic conditions and maintain a steady pace whenever possible. The S4’s responsive engine is tempting to unleash, but restraint saves gas.

Lighten the load. Carrying unnecessary weight in the vehicle also reduces fuel economy. Remove any items from the trunk or backseat that are not essential. Extra weight forces the engine to work harder, diminishing fuel efficiency.
