17 MPG combined. Let’s be blunt: the 2022 Audi RS 7 isn’t winning any hypermiling contests. This is a fire-breathing, twin-turbocharged performance machine cloaked in a sleek, coupe-like sedan body. Fuel efficiency is simply not a priority for those who seek the RS 7’s visceral thrills and head-turning style. Owners prioritize blistering acceleration and dynamic handling above all else, and they accept the consequences at the pump.

City and highway performance

The EPA estimates that the RS 7 achieves 15 MPG in the city and 22 MPG on the highway. The city figure reflects stop-and-go traffic and the frequent use of the throttle to exploit the car’s immense power. The highway number is understandably better, but even cruising at a steady speed, the RS 7’s powerful engine requires a substantial amount of fuel. The eight-speed automatic transmission helps maximize efficiency when possible, but its primary mission is still providing quick, smooth shifts to enhance performance. Don’t expect miracles.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,400 for the 2022 Audi RS 7. This is based on driving 15,000 miles per year and using national average fuel prices. Of course, individual fuel costs will vary greatly depending on driving habits, location, and current gas prices. The RS 7 also requires premium gasoline, further increasing the cost of ownership. For context, be sure to review all Audi fuel economy data to understand Audi’s lineup as a whole.

Real-world expectations

Real-world fuel economy for the RS 7 can vary significantly. Aggressive driving, frequent short trips, and extended idling will all negatively impact fuel consumption. It’s not uncommon to see average MPG figures dip below the EPA estimates, especially in city driving. On long highway journeys with a moderate driving style, exceeding the EPA highway number is possible, but requires conscious effort. The car’s inherent desire to accelerate quickly makes frugal driving a constant battle.

How it compares

Competitors to the RS 7 offer a mixed bag of fuel efficiency. The BMW M5 Competition, with its 4.4-liter twin-turbo V8, posts EPA ratings of 15 MPG city and 21 MPG highway, virtually identical to the RS 7. The Mercedes-AMG E63 S Sedan, powered by a 4.0-liter twin-turbo V8, achieves a slightly better 16 MPG city and 23 MPG highway. These differences are negligible. Buyers in this segment aren’t cross-shopping based on a single MPG point, but rather focusing on the overall driving experience and brand appeal. If you’re looking across the spectrum of the RS line, you can review the RS MPG across all years.

Tips to maximize efficiency

Resist the urge to constantly exploit the engine’s power. The RS 7’s twin-turbo V8 is intoxicating, but frequent hard acceleration will severely impact fuel economy. Drive smoothly and anticipate traffic flow to minimize unnecessary braking and acceleration. Use the “Comfort” driving mode for everyday commuting. It softens throttle response and optimizes the transmission for efficiency without completely sacrificing performance.

Ensure that your tires are properly inflated. Underinflated tires increase rolling resistance, which can significantly reduce fuel economy. Check your tire pressure regularly and maintain the recommended inflation levels found on the door jamb sticker.

Minimize idling time. The RS 7 consumes a surprising amount of fuel while idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engine start/stop systems, while not available on this vehicle, are designed to do this automatically to save fuel.

Remove unnecessary weight from the vehicle. Extra weight increases the amount of energy required to accelerate and maintain speed. Remove any items from the trunk or passenger compartment that you don’t need.
