17 MPG combined. Let’s be brutally honest: anyone considering the 2022 Audi RS 6 Avant isn’t prioritizing fuel efficiency. They’re buying a 591-horsepower, twin-turbocharged V8-powered rocket ship cloaked in the practical (and undeniably cool) body of a station wagon. The trade-off for supercar-level performance and cargo capacity is, unsurprisingly, time spent at the gas pump.

City and highway performance

The EPA estimates indicate a rating of 15 MPG in the city and 22 MPG on the highway. The differences reflect the realities of driving a high-performance vehicle. In stop-and-go urban environments, the RS 6’s prodigious power is largely unused, and its weight becomes a detriment. Achieving the higher highway rating requires a disciplined right foot; consistent acceleration and maintaining higher speeds will drink fuel quickly in this car. The eight-speed automatic transmission, though smooth and responsive, is often working to find the optimal gear to balance performance and economy, a constant push and pull that impacts efficiency. This is a case where the driving experience takes precedence over economy.

Annual fuel cost

The EPA calculates that the average owner of a 2022 Audi RS 6 Avant will spend approximately $3,400 on fuel annually. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price for premium gasoline, which is the recommended fuel for optimal performance in this vehicle. Keep in mind that this is merely an average; depending on driving habits and the aggressiveness of your driving style, expect this figure to be significantly higher.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy in the RS 6 Avant will likely vary. Owners who frequently use the car’s performance capabilities, particularly its rapid acceleration and high-speed cruising abilities, can expect lower fuel economy than the EPA estimates. Conversely, those who drive more conservatively, particularly on the highway, might see figures closer to, or even slightly better than, the 22 MPG rating. Regular maintenance, including proper tire inflation and timely oil changes, can also have a minor but positive impact on fuel efficiency. It’s crucial to remember that this car rewards enthusiastic driving, and that reward comes at the expense of fuel consumption.

How it compares

Comparing the RS 6 Avant’s fuel economy to its rivals paints a revealing picture. The Porsche Panamera Turbo Sport Turismo, another high-performance wagon, achieves a similar 17 MPG combined, which showcases the inherent trade-offs in this segment. The Mercedes-AMG E 63 S Wagon is rated at 19 MPG combined, offering a slightly better fuel economy, though still far from frugal. It is important here to remember that this MPG is achieved in a lab environment. The BMW X5 M, a performance SUV that offers comparable power and practicality, achieves a combined 15 MPG. The RS 6 buyer isn’t cross-shopping a Prius; they are making a conscious decision to prioritize performance and utility over fuel savings. See RS MPG across all years.

Tips to maximize efficiency

While the RS 6 Avant is not designed for maximum fuel efficiency, there are a few strategies owners can employ to mitigate fuel consumption. Reducing unnecessary weight in the vehicle can have a subtle but noticeable effect, especially in city driving. Remove any non-essential items from the cargo area to reduce the vehicle’s overall mass.

Gentle acceleration and smooth braking are key to minimizing fuel consumption. Avoid aggressive launches and hard braking, as these actions rapidly deplete fuel. Anticipate traffic conditions and maintain a consistent speed whenever possible.

Use the Audi Drive Select system to choose the “Efficiency” mode when appropriate. This mode adjusts the engine and transmission settings to prioritize fuel efficiency, although it does temper the car’s performance capabilities. It’s perfect for highway cruising when high performance isn’t needed.

Regularly check tire pressure and ensure that tires are inflated to the recommended levels. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Also, stick with the factory-specified tire size and type, as aftermarket tires can sometimes increase rolling resistance.

Consider enrolling in a safe driving course focusing on eco-driving techniques. These courses can provide valuable insights into optimizing fuel efficiency without sacrificing safety. Many racing schools also offer tips for performance driving, which includes optimizing fuel usage.
