The 2015 Audi A4 quattro 2.0L’s 24 MPG combined won’t win any fuel efficiency contests, but it’s an acceptable compromise for drivers who want all-weather confidence and a refined experience over saving gas. This car isn’t solely about saving gas, it’s about having a premium sedan with the surefootedness of quattro all-wheel drive, and the fuel consumption reflects that trade-off.

City and highway performance

The EPA estimates the 2015 Audi A4 quattro at 21 MPG in the city and 30 MPG on the highway, a split that reflects the energy demands of stop-and-go driving versus the more consistent pace of open-road cruising. The city figure shows the impact of frequent acceleration and braking, while the highway number suggests that the turbocharged 2.0L engine settles into a relatively efficient groove at higher speeds. A heavy foot will quickly erode both numbers, so treat the accelerator with respect to see results closer to the EPA estimates.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2015 Audi A4 quattro 2.0L at $2,400, based on driving 15,000 miles per year and using national average fuel prices. This figure helps prospective buyers understand the ongoing ownership expenses. Remember that this is just an estimate, individual driving habits, local fuel prices, and even weather conditions can all influence your actual fuel costs. If you drive significantly more than 15,000 miles annually, or live in an area with higher fuel costs, expect to spend more. For example, someone racking up 25,000 miles per year could see their fuel bill approach $4,000 based on the EPA’s calculation method.

Real-world expectations

The 2015 Audi A4 quattro 2.0L attracts someone who values the security of all-wheel drive, the responsiveness of a turbocharged engine, and the Audi brand. They understand that these features result in a fuel economy penalty compared to more basic transportation. Highway figures might be slightly above 30 MPG on long road trips, but aggressive driving or primarily city-based commutes will likely result in numbers below 21 MPG. Expect the combined MPG to hover closer to the low 20s for many drivers, especially in colder climates where all-wheel drive is engaged more frequently; keep in mind that ethanol content may also affect fuel economy.

How it compares

The A4’s fuel economy is generally similar to its 2015 competitors. The BMW 328i xDrive, another popular all-wheel drive sport sedan, achieves similar ratings, around 22 MPG combined. A Mercedes-Benz C300 4MATIC also yields comparable numbers. A Lexus IS 250 AWD, while offering a smoother ride, might only deliver around 20 MPG combined. These comparisons are important because buyers in this segment often cross-shop between brands, and fuel economy is just one factor alongside performance, features, and brand image. You can view A4 MPG across all years to get a sense of how consumption has changed for this model over time. Or, look at all Audi fuel economy data.

Tips to maximize efficiency

The 2015 Audi A4 quattro benefits from smooth, consistent acceleration. Avoid jackrabbit starts and hard braking; instead anticipate traffic flow and maintain a steady speed whenever possible, letting the S tronic transmission shift smoothly through its eight speeds. Doing so will improve fuel economy and will reduce wear and tear on the car’s mechanical components.

Ensure your tires are properly inflated to the recommended pressure, which can be found on a sticker in the driver’s side doorjamb. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check tire pressure regularly, especially during seasonal temperature changes, as pressure can fluctuate.

Minimize idling time. The 2.0L engine consumes fuel even when stationary. If you anticipate being stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and the fuel savings from avoiding prolonged idling can add up over time.

Regular maintenance is important for optimal fuel economy. Ensure that the engine air filter is clean and that the engine oil is fresh. A clogged air filter restricts airflow, reducing engine efficiency, while old or degraded engine oil can increase friction and fuel consumption.
