The 2019 Audi A6 quattro 2.0L gets 27 MPG combined, a reasonable number for a luxury sedan that balances performance and all-weather capability. Owners of this A6 value a refined driving experience and styling over ultimate fuel efficiency, understanding that the quattro all-wheel-drive system and turbocharged engine lead to higher fuel consumption than some competitors.

City and highway performance

The EPA estimates the 2019 A6 quattro 2.0L achieves 24 MPG in the city and 32 MPG on the highway. This difference reflects the turbocharged 2.0-liter four-cylinder engine’s characteristics. Stop-and-go traffic in cities makes the engine work harder, reducing its efficiency. However, the engine can cruise efficiently on the open highway. The seven-speed S tronic dual-clutch automatic transmission further optimizes gear selection, allowing the A6 to approach its stated highway MPG. The quattro system provides enhanced grip and stability, but it also adds weight and complexity, slightly increasing fuel consumption compared to front-wheel-drive cars.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Audi A6 quattro 2.0L is $2,150. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on driving habits, the type of fuel used (premium is recommended), and local fuel prices. While $2,150 is a real expense, A6 owners often consider this in the overall cost, knowing that some fuel consumption is expected for a luxury performance sedan.

Real-world expectations

EPA estimates are a baseline, but real-world fuel economy can differ. Driving style is significant. Hard acceleration and braking decrease fuel efficiency. Idling in traffic or cold weather also negatively impacts MPG. Drivers who use a smoother style and mainly drive on the highway may approach or exceed the EPA’s estimates. Regular maintenance, including proper tire inflation and servicing, further optimizes fuel consumption.

Many find that real-world MPG may vary based on these conditions.

How it compares

The 2019 A6 quattro 2.0L is in a competitive class. The BMW 530i xDrive gets a similar 27 MPG combined. The Mercedes-Benz E 300 4MATIC posts around 25 MPG combined. Some competitors may have slightly better efficiency based on trims and options. The Lexus ES 350, does not offer the same performance handling as the A6 or 5 Series, but boasts a combined MPG around 26-27 MPG and uses regular fuel, for potentially lower running costs. For those prioritizing fuel economy, the Volvo S90 T5 FWD, rated at 26 MPG combined, is an alternative, without all-wheel drive. You can explore all Audi fuel economy data to compare models.

Tips to maximize efficiency

Use the Audi Drive Select system. The A6 has driving modes, including “Efficiency” mode that adjusts engine and transmission for fuel economy. This can improve MPG, especially on the highway. Experiment to find the performance/efficiency balance for your driving. Also research A6 MPG across all years to see how the 2019 model compares to previous versions.

Keep tires inflated. Underinflated tires increase rolling resistance, making the engine work harder and using more fuel. Check tire pressure weekly and inflate to the pressure on the driver’s side door jamb. This impacts fuel economy.

Avoid idling. Letting the engine idle consumes fuel. If you’ll be stopped for more than a minute, turn off the engine. Modern cars like the A6 are designed for frequent restarts.

Use cruise control on the highway. Maintaining a consistent speed minimizes acceleration and deceleration, which improves fuel economy. Cruise control prevents speeding up and slowing down, helping the engine operate more efficiently. Disengage cruise control on hills or in heavy traffic.
