17 MPG combined. Let’s be honest, nobody considering a 2021 Audi RS 7 4.0L 8-cyl is prioritizing fuel economy. This is a machine engineered for explosive performance, a statement on wheels that trades efficiency for visceral thrills. The buyer appreciates handcrafted interiors, blistering acceleration, and the unmistakable growl of a twin-turbo V8. They accept the fuel consumption as the cost of admission to a very exclusive club.

City and highway performance

The EPA estimates of 15 MPG in the city and 22 MPG on the highway accurately reflect the RS 7’s dual nature. In urban environments, stop-and-go traffic keeps fuel consumption high. The powerful engine needs fuel to deliver its instant torque, and the RS 7’s weight doesn’t help. However, on the open road, with cruise control set and a steady throttle, hitting the EPA’s 22 MPG isn’t unrealistic. But let’s be honest again: few RS 7 drivers will prioritize steady-state cruising. The temptation to unleash the V8’s full potential will be too great, inevitably impacting fuel consumption.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,400 for the 2021 Audi RS 7. This figure is based on driving 15,000 miles per year, with a 55/45 split between city and highway driving, and using national average fuel prices at the time of calculation. Keep in mind that premium fuel is recommended (if not required) for optimal performance, contributing to the annual expense. This number provides a benchmark, but your personal fuel costs will depend on your individual driving habits and fuel prices in your region. Don’t be surprised if you exceed this estimate, especially if you frequently indulge in the RS 7’s performance capabilities.

Real-world expectations

Don’t expect to consistently achieve the EPA’s numbers. The RS 7’s addictive power delivery encourages spirited driving. Frequent bursts of acceleration, aggressive cornering, and the joy of hearing the exhaust note all contribute to lower fuel economy. A lead foot will easily drop you into the low teens around town and barely above 20 on the highway. That said, mindful drivers who prioritize smooth acceleration and anticipate traffic flow can likely get closer to the EPA estimates. But you’ll need considerable restraint, an attribute not commonly associated with RS 7 ownership.

How it compares

The BMW M8 Gran Coupe, another high-performance four-door coupe, achieves a slightly better 17 MPG city and 24 MPG highway. The Mercedes-AMG GT 63 S offers similar performance and fuel economy, rated at 15 MPG city and 21 MPG highway. Even Porsche‘s Panamera Turbo S E-Hybrid, despite its hybrid powertrain, only manages 18 MPG combined when running on both electric and gasoline power. These rivals offer comparable performance and luxury, but don’t represent a significant leap in fuel efficiency. For drivers considering all Audi fuel economy data, the numbers suggest performance is the prevailing concern, not frugality. This is further evidenced when viewing RS MPG across all years.

Tips to maximize efficiency

While the RS 7 isn’t designed for maximum fuel efficiency, there are still techniques to improve your mileage. Avoid aggressive acceleration and braking. Smooth, progressive throttle inputs are key to keeping fuel consumption in check. Anticipate traffic flow and maintain a safe following distance to minimize unnecessary braking.

Take advantage of the RS 7’s drive mode selector. Selecting the “Efficiency” mode will remap the throttle response and shift points to prioritize fuel saving. While it might dampen the car’s sporty character somewhat, it can make a noticeable difference on longer journeys.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, leading to less gas. Check your tire pressures regularly, using a high-quality gauge, and inflate them to the recommended pressure (found on the doorjamb sticker).

Reduce unnecessary weight. Carrying extra cargo adds to the vehicle’s overall weight, increasing fuel consumption. Remove any items you don’t need to carry regularly.
