The 2023 Audi A4 S-Line quattro 2.0L 4-cyl gets 27 MPG combined, which isn’t going to win any hypermiling awards, but with its turbocharged 2.0-liter engine, it is an acceptable compromise. This isn’t a car purchased for its fuel sipping abilities; it’s a status symbol that blends performance with a degree of practicality. Its target demographic, often young professionals or small families, are seeking German engineering and all-weather confidence, and are willing to trade a few MPGs for the A4’s distinct driving experience and iconic design.

City and highway performance

The official EPA estimates break down to 24 MPG in the city and 32 MPG on the highway. That city figure reflects the demands placed on a turbocharged engine navigating stop-and-go traffic. The A4’s seven-speed dual-clutch automatic (AM-S7) deserves credit for efficiently managing power delivery, but the turbocharger needs fuel to spool up during regular bursts of acceleration. The highway number is more palatable, showcasing the engine’s ability to cruise efficiently once it settles into its stride. Drivers who clock mostly highway miles will find the A4’s fuel consumption surprisingly reasonable, aided by its aerodynamic profile and relatively lightweight construction for a luxury sedan.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Audi A4 S-Line quattro at $2,150, based on driving 15,000 miles per year and using national average fuel prices. This figure provides a standardized benchmark and can useful for comparing running costs across different vehicles. However, your actual fuel expenses may vary significantly depending on where you live, how you drive, and current gasoline prices. With fluctuations in fuel costs always expected, understanding how your driving habits can impact this $2,150 annual estimate can help you save money.

Real-world expectations

While the EPA provides a standardized baseline, real-world fuel economy often deviates. Owners of the A4 S-Line quattro frequently report figures that are around the advertised combined MPG, but drivers who accelerate quickly can expect to see that number dip. Aggressive acceleration, frequent short trips, and extensive idling all impact fuel consumption negatively. Conversely, those who prioritize smooth, consistent driving and adhere to posted speed limits can often match or even slightly exceed the EPA’s estimates, particularly on long highway journeys.

How it compares

Competitors like the BMW 330i xDrive, with a similar turbocharged 2.0-liter engine and all-wheel drive, offers comparable fuel economy rated at 28 MPG combined. The Mercedes-Benz C300 4MATIC, another direct rival, achieves a similar 27 MPG combined. These small differences often become secondary to other purchasing factors, such as technology, interior design, and brand prestige. For those seeking even better fuel consumption, the Lexus IS 300 AWD offers around 22 MPG combined; however, buyers must accept a less engaging driving experience.

Tips to maximize efficiency

The A4’s turbocharged engine benefits from smooth throttle inputs. Avoid aggressive acceleration and strive for consistent speeds to minimize fuel consumption. This is especially important in city driving where constant stop-and-go situations can significantly reduce your MPG.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires create more rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly, especially during seasonal temperature changes.

Reduce unnecessary weight in the vehicle. Extra cargo adds to the load the engine must carry, decreasing fuel efficiency. Remove any items you don’t need on a regular basis, such as sporting equipment or heavy tools.

Use the A4’s driving mode selector judiciously. While “Dynamic” mode unleashes the engine’s full potential, “Comfort” or “Efficiency” modes prioritize fuel conservation by adjusting throttle response and transmission behavior.

Plan your routes to avoid congestion and stop-and-go traffic whenever possible. The A4’s fuel efficiency suffers most in these conditions. A longer route with consistent speeds can often be more fuel-efficient than a shorter route plagued by gridlock.
