The 2016 Audi A6 quattro 2.0L 4-cyl achieves 25 MPG combined, a figure that reflects a balance between performance, all-weather capability, and efficiency. For the buyer who wants German engineering and the all-wheel-drive system, this MPG number is a reasonable trade-off.

City and highway performance

The EPA estimates the 2016 A6 quattro 2.0T at 22 MPG in the city and 32 MPG on the highway. This spread reflects the engine’s responsiveness in stop-and-go traffic and its ability to cruise efficiently at higher speeds. The eight-speed automatic transmission (S8) optimizes fuel consumption by keeping the engine in its best operating range, whether accelerating onto the freeway or maintaining a constant speed on a long road trip. While the city MPG might not be class-leading, the highway figure is respectable and achievable, especially on well-maintained roads.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Audi A6 quattro 2.0L at $2,300. This figure is based on driving 15,000 miles per year and using the national average fuel price. Actual costs will vary based on individual driving habits, local fuel prices, and the specific type of fuel used. However, $2,300 provides a useful benchmark when comparing the A6’s operating costs against other vehicles in its class. It’s a cost factored into the ownership of a prestige vehicle, but one that Audi has worked to keep manageable.

Real-world expectations

While the EPA estimates provide a standardized comparison, real-world fuel economy often differs. Variables such as driving style, weather conditions, and terrain can all impact the MPG you actually experience. Aggressive acceleration, frequent hard braking, and prolonged idling will all decrease fuel economy.

Conversely, smooth driving habits, consistent speeds, and minimal idling will help you approach or even exceed the EPA estimates. Proper tire inflation and regular maintenance are also critical for optimizing fuel efficiency. Many owners report achieving highway MPG figures slightly above the EPA estimate during long drives.

How it compares

The 2016 Audi A6 quattro 2.0L 4-cyl competes with a range of other luxury sedans, and its fuel economy stacks up differently depending on the specific model and configuration. For instance, a BMW 528i xDrive from the same year, also equipped with a 2.0L turbocharged engine and all-wheel drive, delivers similar EPA ratings in most driving conditions. The Mercedes-Benz E300 4MATIC, another competitor, boasts comparable MPG figures, hovering around 22 MPG city and 31 MPG highway.

However, opting for higher-performance engines or larger displacement options in any of these brands will inevitably lead to lower fuel economy. The Lexus GS 350, while offering a more powerful V6 engine, typically sees lower MPG figures, around 20 MPG combined. These comparisons are key for A6 buyers, as they indicate that the Audi offers a competitive balance of luxury, performance, and relative fuel efficiency within its segment.

Tips to maximize efficiency

The 2.0T engine in the 2016 A6 quattro responds well to smooth, deliberate driving. Avoid sudden acceleration and heavy braking to conserve fuel. Anticipate traffic flow and maintain a consistent speed whenever possible.

Take advantage of the A6’s drive select modes. The “Efficiency” mode optimizes various vehicle settings, including throttle response and transmission behavior, to prioritize fuel economy. This is particularly useful for highway driving and gentle city commutes.

Ensure that your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly, especially during temperature changes.

Minimize unnecessary weight in the vehicle. Carrying extra cargo adds to the engine’s workload, leading to less gas use. Remove any items you don’t need to improve efficiency, especially during longer trips.

Regular maintenance is important. A well-maintained engine operates more efficiently. Follow the recommended service schedule for oil changes, air filter replacements, and other essential maintenance tasks. Ignoring maintenance can lead to reduced performance and decreased fuel economy. See all Audi fuel economy data.
