27 MPG combined isn’t going to set any records, but it’s a perfectly respectable figure for the 2017 Audi A4 quattro 2.0L. More importantly, it strikes a balance that appeals to the A4’s core demographic: professionals who prioritize a refined driving experience, advanced technology, and all-weather confidence over saving gas. These buyers want a premium sedan, and they’re willing to accept slightly above-average fuel consumption to get it, as long as it’s not excessive.

City and highway performance

The EPA estimates for the 2017 A4 quattro are 24 MPG in the city and 31 MPG on the highway. The city figure reflects the fuel demands of stop-and-go traffic, where the quattro all-wheel-drive system and the automatic transmission (an AM-S7, meaning “automatic manual, 7-speed”) work harder. The highway number shows what the A4 is capable of when cruising at a steady speed.

The turbocharged 2.0L engine provides ample power for passing and merging, without needing to constantly downshift, which helps to maintain efficiency. However, those numbers are generated under laboratory conditions. Your commute and driving style matter significantly.

Annual fuel cost

The EPA estimates that the 2017 Audi A4 quattro 2.0L will cost $2,150 per year to fuel. This figure is calculated based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices.

Keep in mind that fuel prices fluctuate, and your actual mileage will vary depending on your driving habits and location. If you drive more aggressively, live in a city with high traffic congestion, or use premium fuel (although it’s not required), your annual fuel cost will likely be higher.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often differs. Drivers who regularly commute in congested urban areas might see figures closer to the city estimate of 24 MPG, or even slightly lower. Conversely, those who primarily drive on open highways might experience better fuel economy, potentially exceeding the 31 MPG highway rating.

Factors like tire pressure, vehicle maintenance, and the use of accessories like air conditioning can also impact fuel consumption. It’s essential to track your own fuel economy over time to get a realistic understanding of what to expect from your specific driving conditions.

How it compares

The 2017 A4 quattro’s fuel economy places it roughly in the middle of its competitive set. The BMW 330i xDrive, similarly equipped with a 2.0L turbo and all-wheel drive, achieves an EPA-estimated 27 MPG combined, matching the A4. The Mercedes-Benz C300 4MATIC lands in a similar ballpark, with a combined rating of 26 MPG. The Acura TLX SH-AWD with its V6 engine, though not a direct competitor in terms of engine size, gets around 24 MPG combined.

For buyers weighing prestige, all-wheel drive performance, and fuel costs, the A4’s numbers don’t disqualify it, nor do they particularly distinguish it from its key rivals. You can find all Audi fuel economy data on our site, as well as data for A4 MPG across all years.

Tips to maximize efficiency

Start by ensuring your tires are properly inflated. Check the sticker on the driver’s side doorjamb for the recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. A simple tire pressure gauge can make a noticeable difference in your A4’s fuel efficiency.

Avoid aggressive acceleration and braking. The A4’s turbocharged engine delivers ample power, but using it abruptly will diminish fuel economy. Instead, adopt a smoother driving style, anticipating traffic flow and maintaining a steady speed. The A4’s refined powertrain responds well to gentle inputs and rewards careful driving.

Reduce unnecessary weight in the vehicle. Extra cargo adds load to the engine, requiring it to burn more fuel to maintain performance. Remove items from the trunk and passenger compartment that aren’t essential for your daily commute. Even seemingly small weight reductions can contribute to improved fuel economy over time. Consider removing that golf club set if you’re not heading to the golf course.

Regular maintenance is essential for optimal fuel efficiency. Ensure the engine air filter is clean and that the car receives regular oil changes. A clogged air filter restricts airflow to the engine, reducing performance and increasing fuel consumption. Similarly, old or dirty engine oil can increase friction within the engine, decreasing efficiency. Sticking to the recommended maintenance schedule is the best way to ensure your A4 is running as efficiently as possible.

Use the A4’s selectable driving modes to prioritize fuel economy when appropriate. Selecting “Efficiency” mode (or “Comfort” if Efficiency is not available) tailors the engine and transmission settings to optimize fuel consumption. This mode typically reduces throttle response and encourages earlier upshifts, promoting a more relaxed and fuel-efficient driving experience. It’s worth considering on longer highway journeys.
