The 2018 Audi A3 quattro 2.0L 4-cyl achieves an EPA-estimated 27 MPG combined. This number is respectable for a premium compact sedan that values performance and all-weather traction over saving fuel. The A3 quattro is for affluent urban and suburban professionals who value a refined driving experience, advanced technology, and the security of all-wheel drive. For these drivers, slightly more spent on fuel is an acceptable trade-off for the A3’s advantages.

City and highway performance

The EPA estimates the A3 quattro’s fuel economy at 24 MPG in the city and 31 MPG on the highway. The city figure reflects typical stop-and-go conditions. The A3’s responsive 2.0-liter turbocharged engine and smooth-shifting automatic transmission help it navigate city streets easily, but its all-wheel-drive system consumes more fuel than more basic economy cars. Out on the open road, the A3 quattro cruises comfortably, and the 31 MPG highway rating indicates it’s a capable and relatively efficient long-distance vehicle. Aggressive driving or exceeding speed limits will reduce fuel economy below these estimates.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Audi A3 quattro 2.0L 4-cyl to be $1,600. This is based on driving 15,000 miles per year and the national average fuel price. Remember that this is just an estimate. Actual fuel costs will vary depending on individual driving habits, local fuel prices, and the type of fuel used (premium fuel is recommended for optimal performance). If you drive significantly more or less than 15,000 miles per year, or if gas prices in your area are considerably higher or lower than the national average, your actual fuel costs will differ. The $1,600 figure provides a useful starting point for understanding potential fuel expenses.

Real-world expectations

EPA estimates provide a standardized baseline, but real-world fuel economy can vary based on several factors. Driving style is important. Drivers who accelerate rapidly and brake hard will likely see lower MPG figures than those who drive conservatively. Also, the type of roads driven influences fuel economy. Hilly terrain requires more power and consumes more fuel. Strong headwinds or extreme temperatures can affect MPG. The A3’s all-wheel-drive system adds weight and complexity, which can slightly reduce fuel economy compared to front-wheel-drive vehicles.

How it compares

Understanding the A3 quattro’s fuel economy compared to its competitors is important. The BMW 320i xDrive, a direct rival, achieves a similar 28 MPG combined. The Mercedes-Benz CLA 250 4MATIC manages a slightly better 27 MPG combined. The Acura ILX, while not directly comparable due to its front-wheel-drive configuration, boasts a noteworthy 28 MPG combined and attracts buyers prioritizing fuel savings over AWD. Potential A3 buyers also cross-shop the Lexus IS 300 AWD, which delivers a substantially less appealing 22 MPG combined. This matters to those considering long-term ownership costs and less gas used, even within the premium compact segment. Consider all Audi fuel economy data when shopping.

Tips to maximize efficiency

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tires regularly and inflate them to the pressure specified on the tire placard, typically located on the driver’s side doorjamb. A simple tire pressure gauge can help you ensure your tires are properly inflated.

Avoid unnecessary idling. Letting the engine idle wastes fuel. If you anticipate being stopped for more than a minute, turn off the engine. Modern vehicles, including the A3, start up quickly and efficiently, making it easy to restart when you’re ready to go. This is especially relevant to A3 quattro’s tendency to burn more fuel under normal conditions.

Use cruise control on the highway. Maintaining a consistent speed can improve fuel economy. Cruise control helps to eliminate sudden acceleration and deceleration. Remember to disengage cruise control when driving in adverse weather or heavy traffic.

Avoid aggressive driving habits. Rapid acceleration, hard braking, and high speeds consume more fuel. Drive smoothly and anticipate traffic flow to minimize these behaviors. The A3’s sporty character can be tempting, but resisting the urge to drive aggressively will save money at the pump. Consider the A3 MPG across all years before assuming all models perform similary.

Keep your car well-maintained. Regular maintenance, such as oil changes, air filter replacements, and spark plug replacements, ensures that your engine runs efficiently. A poorly maintained engine can consume more fuel and produce more emissions. Stay on top of your A3’s maintenance schedule to optimize fuel economy and prolong its lifespan.
