With 35 MPG combined, the 2015 Audi A3 2.0L is a frugal choice in the entry-level luxury sedan segment, a class not known for prioritizing fuel conservation. This car appeals to buyers who appreciate German engineering, detailed design, and a premium badge, and also want reasonable ownership costs. Good fuel economy is a welcome bonus.

City and highway performance

The EPA estimates the 2015 A3 2.0L will achieve 31 MPG in city driving and a commendable 41 MPG on the highway. The highway numbers will appeal to commuters and those who take frequent long trips. The peppy 2.0L turbocharged four-cylinder paired with the well-tuned six-speed automatic transmission creates this balance. It delivers enough performance for confident acceleration and passing, avoiding the need to constantly push the engine, which would hurt fuel consumption. The A3 2.0T’s lightweight construction also helps it achieve these impressive figures, allowing the engine to work efficiently without excessive strain.

Annual fuel cost

Based on EPA estimates, the annual fuel cost for the 2015 Audi A3 2.0L sedan is $1,600. This figure is calculated using an estimated 15,000 miles of driving per year, combined with an average fuel price based on national averages when the EPA testing was conducted. Your individual fuel costs will vary based on your driving habits, the type of driving you do (city vs. highway), and the prevailing gasoline prices in your region. The $1,600 figure provides a useful benchmark for comparing the A3’s running costs to those of other vehicles, both within its class and beyond.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world MPG can vary. Aggressive driving, frequent short trips, and bad weather can all hurt fuel economy. Conscientious driving habits, gentle acceleration, and consistent highway cruising can improve these figures. Many 2015 A3 2.0L owners report achieving the combined 35 MPG, and some see figures closer to 45 MPG on long highway trips. Remember to check out the A3 MPG across all years.

How it compares

The A3 2.0T compares favorably to its competitors in fuel efficiency. The BMW 228i earns a combined 28 MPG, making the Audi a winner for those prioritizing lower fuel costs. The Mercedes-Benz CLA250 achieves a similar 30 MPG combined. The Acura ILX offers similar fuel economy at 35 MPG combined, but it lacks the Audi’s refined driving experience and premium interior. The Lexus CT 200h hybrid achieves around 42 MPG combined, but it delivers slower acceleration and a different driving experience than the turbocharged A3.

Tips to maximize efficiency

Use the A3’s “Efficiency” drive mode, if the car has it. This mode adjusts the engine and transmission settings to prioritize fuel conservation, resulting in MPG gains, especially during city driving. Acceleration will be slightly dulled, but fuel savings will be noticeable.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel efficiency. Check your tire pressures regularly, every two weeks, and inflate them to the manufacturer-recommended levels, found on a sticker inside the driver’s side doorjamb.

Reduce the amount of weight in the vehicle. Extra cargo adds to the vehicle’s overall weight, hurting fuel economy. Remove items you don’t need regularly, such as sports equipment, tools, or unnecessary luggage. Every pound matters when trying to increase MPG.

Avoid aggressive driving. Rapid acceleration, hard braking, and excessive speeding consume more fuel. Practice smooth, gentle acceleration and decelerate gradually whenever possible. Maintaining a consistent speed on the highway also contributes to better fuel efficiency.

Consider using cruise control on long highway drives. Cruise control helps keep a steady speed, preventing fluctuations in throttle input that waste fuel. Avoid using cruise control in hilly terrain, as it can lead to downshifts and higher fuel consumption.
