The 2020 Audi A3 2.0L 4-cylinder gets 30 MPG combined, a reasonable figure for a car that blends premium features with everyday usability. It isn’t a hybrid chasing ultimate efficiency, but a refined compact sedan that prioritizes a balance between performance, comfort, and respectable fuel consumption. A3 buyers value driving enjoyment and upscale amenities, accepting this efficiency rating as a fair trade-off.

City and highway performance

The EPA estimates the 2020 Audi A3 fuel economy at 27 MPG in the city and 36 MPG on the highway. The city figure reflects typical stop-and-go driving, with the A3’s responsiveness making it a pleasant companion in urban environments. The highway number demonstrates the A3’s ability to cruise efficiently at consistent speeds, suitable for longer commutes and road trips. This spread between city and highway numbers is typical for vehicles with traditional gasoline engines, where consistent highway speeds allow the engine to operate at their most efficient range.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Audi A3 is $1,450. This figure assumes 15,000 miles driven per year, using national average fuel prices. Spending may vary depending on driving habits, fuel prices in your region, and the type of fuel used (premium fuel is recommended for optimal performance in the A3). While not the lowest annual fuel cost in its class, most A3 buyers find it acceptable given the vehicle’s other attributes.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy can fluctuate based on several factors. Aggressive driving habits, such as frequent hard acceleration and braking, will decrease fuel efficiency. Similarly, carrying extra weight in the vehicle can impact MPG. Weather conditions such as cold temperatures or strong headwinds can also reduce fuel economy.

Proper vehicle maintenance, including regular tire inflation and oil changes, is important for maintaining optimal fuel efficiency. Drivers who prioritize gentle acceleration, anticipate traffic flow, and maintain their A3 meticulously are more likely to achieve or even exceed the EPA estimates, and you can find A3 MPG across all years to compare ratings.

How it compares

The 2020 Audi A3’s fuel economy places it competitively within the compact luxury sedan segment. A direct competitor like the BMW 228i xDrive offers a similar driving experience, delivering around 26 MPG combined. The Mercedes-Benz A220, another key rival, achieves a slightly superior 28 MPG combined. The Acura ILX, frequently chosen for its value, gets around 28 MPG combined. The A3’s fuel economy might not be class-leading, but buyers drawn to Audi’s interior design, technology features, and brand cachet often overlook the slightly lower MPG. These buyers prioritize the total ownership experience, viewing fuel economy as just one piece.

Tips to maximize efficiency

Use the Audi Drive Select system. This system lets you choose different driving modes, including an “Efficiency” mode. When engaged, this mode optimizes the car’s settings for maximum fuel economy by adjusting throttle response, shift points, and even climate control operation.

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

Anticipate traffic and avoid aggressive driving. Sudden acceleration and hard braking waste fuel. Try to maintain a smooth and consistent speed, and anticipate traffic flow to avoid unnecessary stops and starts. This is especially important in city driving, where stop-and-go conditions can significantly impact fuel economy.

Reduce unnecessary weight. Carrying extra weight in your vehicle reduces fuel efficiency. Remove any unnecessary items from your trunk or backseat to lighten the load and improve your MPG. A lighter vehicle accelerates and decelerates more easily, reducing the strain on the engine.
