26 MPG combined is a perfectly reasonable figure for the 2016 Audi S3 2.0L, and it’s unlikely to be a major concern for most buyers. This isn’t a hyper-efficient commuter car; it’s a compact performance sedan delivering serious punch with a turbocharged engine and standard all-wheel drive. Its appeal lies in its blend of daily usability and thrilling performance, and the fuel economy is simply “good enough” for a vehicle with this mission.

City and highway performance

The EPA estimates on the window sticker show 23 MPG in the city and 31 MPG on the highway. The city MPG is particularly relevant for S3 buyers, many of whom will use the car for commuting and running errands in urban environments. The highway number is respectable, but less of a selling point. The S3’s relatively small size and aerodynamic shape help it achieve decent efficiency at higher speeds, but it’s the instant torque of the turbocharged engine that defines the driving experience, and that comes at a cost. In stop-and-go traffic, drivers will find themselves using the available power, dropping their fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Audi S3 at $2,250. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. The calculation uses the national average fuel price at the time of testing. Keep in mind that premium fuel is recommended for the S3, as that’s what the engine is optimized to use, and premium fuel often costs considerably more than regular gasoline. As a result, S3 owners may find themselves spending more than the EPA’s estimate, especially if fuel prices are high in their area.

Real-world expectations

While the EPA numbers offer a standardized benchmark, real-world fuel economy can vary significantly based on driving style, traffic conditions, and even the weather. An aggressive driver who frequently exploits the S3’s performance potential will likely see numbers closer to the low 20s. A more conscientious driver who prioritizes fuel efficiency, employs a light foot, and anticipates traffic flow could potentially exceed the EPA estimates, especially on longer highway trips. Regular maintenance, including properly inflated tires and timely oil changes, also contributes to optimal fuel economy. Remember to check out S3 MPG across all years to see if different model years may have more or less fuel efficiency.

How it compares

The S3 doesn’t exist in a vacuum. Buyers often cross-shop it with other performance-oriented compact cars. The BMW M235i xDrive (later the M240i xDrive), equipped with a turbocharged inline-six engine and all-wheel drive, delivers similar performance but typically achieves slightly worse fuel economy, often around 22-25 MPG combined. The Mercedes-AMG CLA45, another direct competitor, offers even more power but pays the price with real-world fuel economy often hovering around 21-24 MPG. The Volkswagen Golf R, which shares a platform and engine with the S3, offers similar performance and fuel economy (around 23-27 MPG combined), but with a hatchback body style and a slightly different image. These comparisons highlight that the S3 strikes a reasonable balance between performance and efficiency within its segment.

Tips to maximize efficiency

The S3’s turbocharged engine responds well to smooth, deliberate throttle inputs. Avoid abrupt acceleration and hard braking, as these actions waste fuel and contribute to increased wear and tear on the vehicle. Instead, anticipate traffic conditions and maintain a consistent speed whenever possible. Gentle acceleration helps the turbocharger operate more efficiently, reducing fuel consumption.

Use the S3’s drive select modes. In “Efficiency” or “Comfort” mode, the car will prioritize fuel economy by optimizing throttle response, shift points, and even climate control settings. While “Dynamic” mode unleashes the car’s full potential, it also consumes more fuel. Consider using the more efficient modes for daily commuting or longer highway trips.

Proper tire inflation is critical for fuel economy. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly and inflate them to the recommended levels, which can be found on a sticker inside the driver’s side doorjamb. Properly inflated tires also improve handling and extend tire life.

Minimize unnecessary weight in the vehicle. Extra cargo adds load to the engine, decreasing fuel economy. Remove any items you don’t need from the trunk and rear seats. Even small amounts of excess weight can impact fuel consumption over time. and consider removing any roof racks when not in use, as they add aerodynamic drag.

Regular maintenance is essential for optimal fuel efficiency. Ensure that the engine is properly tuned, and replace air filters, spark plugs, and other components according to the manufacturer’s recommendations. A well-maintained engine runs more efficiently, consuming less fuel and producing fewer emissions. For all Audi fuel economy data, and more tips, be sure to check back often.
