18 MPG combined is what drivers who demand supercar performance blended with daily-driver practicality can expect. The 2016 Audi RS 7 is not purchased for its fuel sipping, but for its rapid acceleration, impeccable interior, and subtly aggressive styling. Anyone considering a car with this level of performance knows that fuel efficiency is a secondary concern. But how much of a concern? Let’s look at the details.

City and highway performance

The official EPA ratings are 14 MPG in the city and 25 MPG on the highway. The city figure is optimistic if you plan on enjoying the RS 7’s power. Stop-and-go traffic, combined with the temptation to exploit the 4.0-liter twin-turbo V8’s instant response, will likely result in even lower numbers. The highway figure is more achievable, thanks to the RS 7’s eight-speed automatic transmission and aerodynamic profile. Long cruises can yield decent fuel economy, provided you resist the urge to pass everyone in sight using full throttle. Understanding these factors is key to managing your expectations and your fuel budget.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,200 for the 2016 Audi RS 7. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Premium fuel is a requirement for the RS 7, and its price is factored into that figure. If you drive more aggressively, live in an area with higher fuel costs, or exceed the 15,000-mile average, expect this number to increase. It’s a useful baseline, but not necessarily a precise prediction of your individual spending.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy can vary significantly based on driving style, traffic conditions, and even weather. Owners who regularly engage the RS 7’s launch control or spend most of their time in dense urban environments will likely see figures closer to 12 MPG or even lower. On the other hand, drivers who prioritize smooth acceleration and use cruise control on long highway stretches might achieve closer to 27 MPG. Tire pressure, maintenance, and even the quality of the fuel can also influence your mileage. The RS 7 rewards a gentle foot, but encourages aggressive driving.

How it compares

Competitors like the Mercedes-AMG CLS63 S of the same year offer similar performance, but with slightly worse fuel economy, rated at 16 MPG combined. The BMW M6 Gran Coupe, another powerful four-door coupe, achieves 17 MPG combined. These differences, while seemingly small, can add up over the lifespan of the vehicle.

These cars are not cross-shopped against hybrids or economy cars; buyers are comparing performance metrics first, with fuel efficiency being a secondary consideration. See RS MPG across all years to view historic data for this model. For more details, check all all Audi fuel economy data.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The RS 7’s twin-turbo V8 is powerful, but every hard launch and sudden stop translates directly into wasted fuel. Smooth, gradual inputs will keep the engine operating more efficiently.

Use the Audi Drive Select system. Experiment with the “Efficiency” mode, which adjusts engine mapping and transmission behavior to prioritize fuel conservation. While it may dampen throttle response, it can make a difference on long highway drives.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and maintain the recommended levels.

Minimize idling. Letting the engine idle for extended periods wastes fuel. If you anticipate being stopped for more than a minute, turn off the engine. Modern vehicles are designed to restart quickly and efficiently.

Plan your routes strategically. Avoiding congested areas and peak traffic times can improve your fuel economy. Opt for routes with fewer stoplights and less start-and-stop driving.
