The 2020 Audi A6 quattro 2.0L returns 27 MPG combined, showing Audi’s commitment to efficiency without sacrificing the driving experience. It’s not the highest MPG in the mid-size luxury sedan class, but it strikes a good balance for buyers who want performance, technology, and all-weather confidence. This car is for professionals, suburban residents, or anyone who values a refined driving experience regardless of the conditions. They accept this fuel economy because they’re getting quattro all-wheel drive, a well-crafted interior, and a badge that represents understated success.

City and highway performance

The EPA estimates for the 2020 Audi A6 quattro 2.0L break down to 24 MPG in the city and 32 MPG on the highway. The city figure reflects the stop-and-go nature of urban commutes, where the engine’s start-stop system works to conserve fuel when idling. The reliable low-end torque from the turbocharged 2.0-liter engine also helps make the most of each drop of fuel, minimizing the need for aggressive acceleration.

On the highway, the A6 quattro shines. The seven-speed S tronic dual-clutch transmission delivers smooth and efficient gear changes, allowing the engine to cruise comfortably at lower RPMs. The car’s aerodynamic design contributes to its highway fuel efficiency by reducing drag and minimizing wind resistance.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2020 Audi A6 quattro 2.0L is estimated at $2,150. This figure, based on driving 15,000 miles per year and using national average fuel prices, is a benchmark for typical usage. Your actual fuel expenses may vary depending on your driving habits, local fuel prices, and the specific conditions in which you drive. Consistent hard acceleration or frequent short trips can negatively affect your mileage and increase your fuel expenses beyond the $2,150 estimate.

Real-world expectations

While EPA estimates provide a useful baseline, real-world fuel economy often differs based on individual driving habits and conditions. Drivers who accelerate quickly or encounter heavy traffic might find their MPG closer to the lower end of the EPA range, or even slightly below. On the other hand, those who prioritize smooth acceleration, maintain consistent speeds on the highway, and minimize idling can expect to achieve, or even exceed, the EPA estimates. Factors such as tire pressure, vehicle maintenance, and the use of accessories like air conditioning can also influence fuel consumption.

How it compares

In the mid-size luxury sedan segment, the 2020 Audi A6 quattro 2.0L holds its own in terms of fuel economy. The BMW 530i xDrive, for example, offers a similar driving experience with an EPA-estimated 25 MPG combined. The Mercedes-Benz E350 4MATIC achieves about 26 MPG combined. The Lexus ES 350, with its standard front-wheel drive, achieves a slightly better 26 MPG combined, appealing to buyers prioritizing efficiency over all-weather capability. The Acura TLX SH-AWD offers AWD like the A6, but can only muster 24 MPG combined. These comparisons are important for the A6 buyer, since they’re likely cross-shopping these models and weighing fuel efficiency alongside factors like interior design, technology, and brand reputation.

Tips to maximize efficiency

Use the Audi Drive Select system. Experiment with the different driving modes and familiarize yourself with “Efficiency” mode. This setting optimizes engine and transmission parameters to prioritize fuel economy, often softening throttle response and encouraging earlier upshifts. Dynamic mode provides a more exhilarating driving experience, but it uses more fuel.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tires regularly and inflate them to the recommended pressure listed on the door jamb sticker. Proper inflation improves fuel economy, enhances handling and extends the lifespan of your tires.

Keep idling time to a minimum. Idling wastes fuel and produces unnecessary emissions. If you anticipate being stationary for more than a minute or two, turn off the engine. The A6 quattro’s start-stop system shuts off the engine automatically at traffic lights and brief stops, further contributing to fuel savings. Make sure this system is active unless you have a specific reason to disable it.

Avoid aggressive driving habits. Rapid acceleration, hard braking, and high speeds use significantly more fuel than smooth, consistent driving. Anticipate traffic flow and maintain a steady pace whenever possible. Cruise control on the highway can help maintain a consistent speed and optimize fuel efficiency. Consider leaving a bit earlier for your commute to relax your driving and not be as aggressive.

Maintain a regular maintenance schedule. Regular maintenance, including oil changes, air filter replacements, and spark plug replacements, ensures that your engine runs efficiently. A well-maintained engine consumes less fuel and produces fewer emissions. Ignoring maintenance can lead to reduced performance and increased fuel consumption over time.
