With 17 MPG combined, the 2018 Audi RS 7 isn’t designed for fuel efficiency. It’s a high-performance, four-door coupe made for incredible speed and striking style; fuel economy is a secondary concern. The RS 7 buyer understands this trade-off and accepts it for the exciting combination of luxury, technology, and strong power this car provides.

City and highway performance

The RS 7’s EPA ratings are 14 MPG in the city and 24 MPG on the highway. The city number reflects the demands on a large-displacement, turbocharged engine when navigating stop-and-go traffic. Expect frequent trips to the gas station if you mainly drive in the city. On the open road, the RS 7 does better. Its automatic transmission and engine management system allow it to cruise more efficiently, but aggressive driving will quickly eliminate any gains. The highway number is achievable, but requires a careful right foot. If you’re frequently engaging the turbos for overtaking, expect real-world highway MPG to fall closer to the combined figure.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2018 Audi RS 7 is $3,400. This estimate is based on driving 15,000 miles per year and using national average fuel prices. Actual costs will vary depending on individual driving habits, fuel prices in your area, and the type of fuel used. Given the RS 7’s high-performance engine, premium fuel is strongly recommended.

Real-world expectations

While the EPA figures offer a baseline, real-world MPG for the RS 7 can change a lot. Drivers who accelerate quickly will likely see numbers below 17 MPG on average. However, those who prioritize fuel efficiency and spend a lot of time on the highway might achieve slightly better results. The RS 7 encourages enthusiastic driving, and its performance capabilities often tempt drivers to exploit its full potential, which hurts fuel consumption. The driving mode selected also makes a difference; selecting an efficiency mode will reduce throttle response and shift points, potentially saving fuel.

How it compares

Compared to other performance sedans and coupes in its class, the RS 7’s fuel economy is typical. The BMW M6 Gran Coupe, for example, offered a similar combination of performance and luxury but only managed 17 MPG combined using a similar engine configuration. A Porsche Panamera Turbo, while offering superior performance, posted official figures around 18 MPG combined. Even slightly less powerful options such as the Mercedes-AMG CLS63 S achieved similar numbers. The RS 7 buyer prioritizes performance and luxury over fuel efficiency, so these slight differences in efficiency matter less. You can view all Audi fuel economy data for more models.

Tips to maximize efficiency

Avoid aggressive acceleration. The RS 7’s powerful engine responds instantly to throttle input. Gentle acceleration allows the turbos to spool up gradually, minimizing fuel consumption. Anticipate traffic flow to avoid unnecessary braking and acceleration.

Use the Audi Drive Select system carefully. The “Efficiency” mode optimizes engine and transmission settings for fuel economy. While it might not be ideal for spirited driving, it can make a noticeable difference during highway cruising and around-town errands. Don’t forget to compare RS MPG across all years.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, negatively impacting fuel economy. Check your tire pressure regularly and inflate to the recommended levels found on the door jamb or in the owner’s manual.

Minimize idling. Excessive idling wastes fuel and contributes to emissions. If you expect to be stationary for more than a minute or two, turn off the engine. The RS 7, like many modern cars, consumes fuel even when idling.

Keep the car properly maintained. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended service schedule, including regular oil changes, air filter replacements, and spark plug inspections. These simple maintenance tasks can prevent performance degradation and ensure optimal fuel economy.
