27 MPG combined isn’t going to win the 2022 Audi S3 any hypermiling awards, but for the type of buyer drawn to this sharp-handling, premium compact sedan, it strikes a reasonable balance. This isn’t a car primarily purchased for its miserly fuel consumption. People choose the S3 for its punchy turbocharged engine, quattro all-wheel drive, and upscale interior, accepting its fuel economy as a trade-off for performance and prestige.

City and highway performance

The EPA estimates the S3 will achieve 23 MPG in the city and 32 MPG on the highway. The city figure reflects the realities of stop-and-go traffic, where the engine works harder and spends more time idling. The highway number showcases the efficiency of the seven-speed dual-clutch automatic transmission, which allows the engine to cruise at lower RPMs, conserving fuel on long journeys. While 32 MPG isn’t groundbreaking for a small sedan, it’s a respectable figure considering the S3’s performance-oriented nature and standard all-wheel drive system. This is a car that encourages spirited driving, which inevitably impacts fuel economy.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2022 Audi S3 is $2,150. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that premium fuel is recommended (and arguably required to achieve optimal performance), so price fluctuations at the pump can significantly impact this annual cost. Drivers who cover more miles or live in areas with higher fuel costs can expect to spend considerably more. While $2,150 is a useful benchmark, it’s crucial to factor in your own driving habits and local fuel prices for a more accurate estimate. You can also view S3 MPG across all years to compare.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often differs. The aggressive driving often encouraged by the S3’s responsive engine will definitely pull down the MPG. Factors like traffic congestion, weather conditions, and even tire pressure can also influence fuel consumption. Drivers who primarily commute in stop-and-go traffic may find themselves closer to the city estimate, while those who frequently take longer highway trips may see numbers closer to or even slightly exceeding the highway rating. Using the “Efficiency” drive mode can help rein in fuel consumption, but it also dulls the throttle response. Most S3 owners prioritize performance over pinching pennies, but conscientious drivers can still mitigate the fuel costs.

How it compares

The S3 resides in a competitive segment. The BMW 228i xDrive, another sporty compact with all-wheel drive, achieves a slightly higher 28 MPG combined. The Acura Integra, particularly the sporty A-Spec trim, offers a more frugal 30 MPG combined, but lacks the all-out performance and premium feel of the Audi. Even within the Audi family, the A4 offers similar levels of luxury but with slightly better fuel economy, coming in at 28 MPG combined for the all-wheel-drive version. These comparisons reveal the compromises involved. Buyers choosing the S3 are placing a higher value on performance and driving dynamics, accepting a slight penalty in fuel economy compared to more economy-focused alternatives.

Tips to maximize efficiency

Use the Audi Drive Select system. The “Efficiency” mode softens throttle response and optimizes the transmission for fuel savings. While it reduces the car’s outright performance, it can make a noticeable difference in fuel consumption, particularly during city driving.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Check your tire pressure regularly and inflate them to the recommended levels found on the sticker inside the driver’s side door.

Avoid unnecessary idling. Letting the engine idle for extended periods wastes fuel. If you’re stopped for more than a minute or two, turn off the engine. The S3’s engine restarts quickly when you’re ready to go.

Lighten your load. Extra weight in the car requires more energy to move. Remove any unnecessary items from the trunk and passenger compartment to improve fuel efficiency. This is especially true in a car as small as the S3 where every pound makes a difference.

Anticipate traffic flow. By looking ahead and anticipating changes in traffic, you can avoid harsh acceleration and braking, which significantly impact fuel economy. Smooth and consistent driving is the key to maximizing efficiency in any vehicle, even one as performance-oriented as the S3.
