The 2022 Audi A6 quattro models equipped with the supercharged 3.0L V6 get 24 MPG combined. That number might seem unremarkable, but it represents a well-considered compromise for the buyer who prioritizes performance, all-weather capability, and understated luxury over outright fuel efficiency. These are drivers who appreciate the A6’s effortless power delivery and confident handling in all conditions, and are willing to trade a few MPG for that experience.

City and highway performance

The EPA estimates for the 2022 Audi A6 quattro 3.0L are 21 MPG in the city and 30 MPG on the highway. These numbers reflect distinct driving patterns. City driving, characterized by frequent stops and starts, puts a greater strain on fuel economy, while highway cruising allows the engine to operate at a more consistent and efficient speed. The supercharged V6 and seven-speed automatic transmission work competently in both environments, but urban driving inherently impacts fuel consumption. The highway figure is more impressive, showcasing the powertrain’s ability to deliver good fuel economy when conditions allow. But the combined 24 MPG is an honest assessment reflecting a mix of real-world use. To see A6 MPG across all years, you can explore the data here.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2022 Audi A6 quattro 3.0L will be $2,400. This calculation is based on driving 15,000 miles per year using a mix of city and highway driving conditions and assumes national average fuel prices. Keep in mind that your actual fuel costs may vary depending on your driving habits, the type of fuel you use (premium is recommended for optimal performance), and fluctuations in fuel prices. It’s a useful benchmark for comparing the cost of ownership against other vehicles, but treat it as an estimate, not an exact figure.

Real-world expectations

While the EPA provides a standardized testing procedure, real-world fuel economy often differs. Aggressive driving, heavy traffic, and even weather conditions can impact your MPG. Drivers who frequently engage the A6’s sport mode or spend most of their time in stop-and-go traffic will likely see lower numbers than the EPA estimates. Conversely, those who prioritize smooth acceleration and consistent speeds on the open road might achieve figures closer to, or even slightly exceeding, the 30 MPG highway rating. Pay attention to trip computers, which can provide insight on driving habits that cost you fuel. Use them, along with an awareness of your typical routes, to help shape smarter habits that benefit your wallet. Premium fuel also ensures that the engine operates as intended, extracting optimum efficiency and performance.

How it compares

In the mid-size luxury sedan segment, some competitors offer slightly better fuel economy, but often at the expense of all-wheel drive or a less powerful engine. For example, the BMW 530i with rear-wheel drive achieves a combined 28 MPG, but lacks the all-weather confidence of the A6 quattro. The Mercedes-Benz E350 4Matic offers similar performance and luxury, but its combined MPG of 25 is negligibly better. The Volvo S90 B6 AWD gets approximately 26 MPG combined. The Lexus ES 350, while not a direct competitor in terms of driving dynamics, boasts a combined 26 MPG with its front-wheel drive configuration. The A6 buyer is often willing to accept a slight MPG penalty for the security and performance benefits of quattro all-wheel drive and the strong power of the supercharged V6.

Tips to maximize efficiency

Avoid aggressive acceleration and hard braking. The A6 quattro’s ample power can be tempting, but a gentle touch on the throttle will help you maintain better fuel economy. Anticipate traffic flow and coast whenever possible, minimizing the need for sudden stops and starts. This is especially important in city driving.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended levels. Also, seasonal changes can affect tire pressure, so check periodically or consider investing in a home tire inflator you can keep in the garage.

Reduce unnecessary weight in the vehicle. Carrying extra cargo adds to the vehicle’s overall weight, which impacts fuel consumption. Remove any items you don’t need to carry on a regular basis. And if you use roof racks or carriers, consider removing them when not in use, as they can increase aerodynamic drag.

Use the A6’s drive select modes wisely. The efficiency mode optimizes fuel economy by adjusting engine and transmission settings. While it might slightly reduce performance, it can make a noticeable difference in fuel consumption during commutes or long highway drives. You’re still getting the core A6 driving experience (just with slightly blunted throttle response), so don’t hesitate to employ that setting in the right situations.
