28 MPG combined won’t set any fuel economy records, but it’s a good balance for the 2025 Audi A3 quattro 2.0L 4-cyl. Buyers in this segment aren’t only focused on maximizing gas mileage; they want a mix of performance, all-weather traction, and premium features. The A3 quattro satisfies those desires while remaining reasonably efficient.

City and highway performance

The EPA estimates the 2025 Audi A3 quattro at 24 MPG in the city and 34 MPG on the highway. The city figure reflects the demands of stop-and-go traffic, where the turbocharged engine works harder and the automatic transmission cycles through gears more frequently. The highway number demonstrates the A3’s ability to cruise efficiently at consistent speeds. The 2.0L 4-cylinder engine paired with the responsive seven-speed automatic transmission delivers these MPG numbers. Drivers who enjoy backroad carving and spirited takeoffs will likely see lower numbers, while disciplined highway drivers can expect to meet or even slightly exceed the EPA estimate.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Audi A3 quattro at $2,050. This is based on driving 15,000 miles per year and using national average fuel prices. Your individual fuel costs can vary significantly, depending on your driving habits, local fuel prices, and the type of fuel you use. This $2,050 estimate provides a benchmark to compare the A3 against other vehicles, especially those with similar performance or luxury features.

Real-world expectations

While the EPA provides a useful benchmark, real-world fuel economy varies. Aggressive driving, frequent short trips, cold weather, and carrying extra weight can all negatively affect your gas mileage. Conversely, gentle acceleration, consistent highway speeds, warm weather, and proper tire inflation can help you achieve better-than-expected fuel economy. With the A3 quattro, understand that engaging the “Dynamic” driving mode will sharpen throttle response and hold gears longer, resulting in lower MPG if used all the time.

Driving style matters. Expect MPG to drop if you drive aggressively.

How it compares

The A3 quattro faces competition from other compact luxury sedans. The BMW 228i xDrive, another all-wheel-drive performer, achieves a slightly lower 27 MPG combined. The Mercedes-Benz CLA 250 4MATIC comes close with 28 MPG combined. The Acura Integra A-Spec with its smaller 1.5L engine achieves about 30 MPG combined. The A3 quattro’s all-wheel-drive system adds weight and complexity, which impacts fuel economy compared to front-wheel-drive competitors. Buyers select the A3 quattro understanding there will be a fuel economy trade-off for enhanced traction and handling in all weather conditions.

Tips to maximize efficiency

Maintain proper tire inflation. Audi specifies the optimal tire pressure on a sticker inside the driver’s side doorjamb. Inflating your tires to the recommended pressure reduces rolling resistance, which directly translates to improved fuel economy. Check your tire pressure regularly, especially during seasonal temperature changes.

Use cruise control on the highway whenever possible. Maintaining a consistent speed minimizes unnecessary acceleration and deceleration, which can significantly impact fuel consumption. Cruise control allows the A3’s engine management system to optimize fuel delivery for steady-state driving.

Avoid aggressive acceleration and hard braking. The A3’s turbocharger delivers ample power, but resist the urge to constantly use it. Gentle acceleration and smooth braking techniques minimize wasted energy and improve fuel efficiency. Anticipate traffic flow and maintain a safe following distance to avoid sudden stops.

Consider using “Efficiency” or “Comfort” mode. The Audi Drive Select system offers various driving modes that adjust throttle response, steering effort, and transmission shift points. Selecting “Efficiency” or “Comfort” mode prioritizes fuel economy by softening throttle response and promoting earlier upshifts.

Keep up with scheduled maintenance. Regular oil changes, air filter replacements, and spark plug inspections ensure that your A3’s engine is running efficiently. A well-maintained engine consumes less fuel and performs optimally. You can find all Audi fuel economy data on this site and read more about A3 MPG across all years.
