29 MPG combined won’t set any fuel efficiency records, but it’s a perfectly reasonable figure for the 2025 Audi A4 quattro 2.0L. More importantly, its average MPG isn’t the main point. This is a compact luxury sedan with standard all-wheel drive, aimed at buyers who prioritize a refined driving experience over maximizing every last mile from a gallon of fuel. The A4 quattro buyer wants a comfortable, stylish, and sure-footed car that’s enjoyable to drive, and they’re prepared to make a reasonable compromise on fuel efficiency to get it.

City and highway performance

The 2025 A4 quattro’s EPA ratings break down to 26 MPG in the city and 36 MPG on the highway. The city number is adequate, reflecting the stop-and-go nature of urban driving and the A4’s size. The highway figure, however, is where the A4 excels, making it a comfortable and relatively efficient long-distance cruiser. The turbocharged 2.0L engine, paired with the seven-speed automatic transmission (AM-S7), balances responsiveness with fuel conservation at highway speeds. This is especially true if you use the car’s efficiency drive mode when hitting the open road.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2025 Audi A4 quattro 2.0L will be approximately $2,000. This is based on driving 15,000 miles per year, using a hypothetical national average fuel price. Your actual fuel costs will vary depending on how much you drive, the type of driving you do, and the current prices at your local gas stations. Check on all Audi fuel economy data to better understand fuel costs.

Real-world expectations

EPA ratings provide a standardized benchmark, but real-world fuel economy varies based on driving habits and conditions. Expect numbers close to the EPA estimates if you drive with a light foot and do a mix of city and highway driving. Aggressive acceleration, frequent hard braking, and prolonged idling will negatively impact fuel efficiency. Cold weather and carrying extra weight can also reduce your MPG.

How it compares

The A4 quattro isn’t alone in the compact luxury sedan market. The BMW 330i xDrive, also with standard all-wheel drive, achieves a similar 28 MPG combined. The Mercedes-Benz C300 4MATIC is rated at 27 MPG combined. The Acura TLX SH-AWD, another all-wheel-drive competitor, is rated lower, at 24 MPG combined. The Lexus IS350 AWD sits around 22 MPG combined. For a buyer prioritizing less gas above all else, the A4’s numbers are competitive within its class of all-wheel-drive rivals. Comparing these figures with A4 MPG across all years can provide useful insights.

Tips to maximize efficiency

Smooth and steady acceleration is key to maximizing fuel economy in the A4 quattro. Avoid sudden bursts of speed and try to anticipate traffic flow to minimize unnecessary braking. The turbocharged engine responds well to gentle inputs, and you’ll see an improvement in your MPG by adopting a more relaxed driving style.

Make good use of the Audi Drive Select system. The “Efficiency” mode optimizes the engine and transmission settings for maximum fuel economy. It might slightly reduce throttle response, but it can make a difference on longer trips, especially on the highway. Experiment to find the right balance between performance and efficiency for your driving needs.

Regular maintenance is critical for optimal fuel economy. Ensure that your tires are properly inflated, as underinflated tires create more rolling resistance and decrease MPG. Stick to the manufacturer’s recommended maintenance schedule for oil changes, air filter replacements, and other essential services. A well-maintained engine runs more efficiently and consumes less fuel.

Reduce excess weight in the vehicle. Carrying unnecessary cargo in the trunk or back seat adds to the vehicle’s load and reduces fuel efficiency. Remove any items you don’t need regularly. Every little bit helps, especially in city driving where you’re constantly accelerating and decelerating.
