84 MPG combined is a startling figure for any vehicle, but it’s especially remarkable for the 2025 Audi RS e-tron GT Performance. This isn’t a hybrid sipping fuel; it’s an all-electric, high-performance grand tourer designed to deliver blistering acceleration and stunning driving dynamics. The fuel economy, expressed as an MPGe equivalent, is secondary to its mission. Buyers aren’t prioritizing maximum range above all else. They’re seeking an exhilarating driving experience with the bonus of near-silent running and instant torque. They appreciate the lower fuel costs of electric driving, but the raw performance is the primary draw.

City and highway performance

The EPA estimates for the RS e-tron GT Performance break down as 85 MPGe in the city and 82 MPGe on the highway. This slight advantage in city driving is typical for electric vehicles, which benefit from regenerative braking in stop-and-go traffic. On the open road, aerodynamic drag becomes a larger factor, and the inherently weighty nature of a performance EV can slightly reduce its relative efficiency. However, both figures underscore the impressive engineering baked into Audi’s electric powertrain. This is a car that thrives on both twisty backroads and long-distance cruising.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Audi RS e-tron GT Performance at just $900. This calculation is based on driving 15,000 miles per year and using the national average electricity cost. Of course, individual expenses will differ depending on driving habits, local electricity prices, and charging patterns. Those with access to cheaper off-peak electricity, or those who use workplace charging, will likely see even lower costs. This figure highlights a striking advantage of electric vehicles: the potential for significant savings compared to a similarly performing gasoline-powered car. It makes owners think less about fuel and more about enjoying the ride.

Real-world expectations

While the EPA figures provide a valuable benchmark, real-world MPGe will vary. Aggressive driving, frequent use of the car’s exhilarating launch control, and consistently high speeds will all impact efficiency. Ambient temperature also plays a role, as cold weather can reduce battery performance and increase energy consumption. Conversely, gentle acceleration, predictive driving techniques, and preconditioning the cabin while plugged in can help maximize range and align with, or even exceed, the EPA estimates. Drivers who use the adjustable regenerative braking settings can also recoup more energy, especially around town.

How it compares

Compared to other performance EVs in its class, the RS e-tron GT Performance holds its own well. The Porsche Taycan Turbo, a close relative underneath the skin, sees an EPA-estimated 76 MPGe combined. The Tesla Model S Plaid also offers immense power, but sits at an EPA-estimated 116 MPGe combined, emphasizing Tesla’s focus on range and efficiency, even within its performance models. The Mercedes-AMG EQS offers an EPA-estimated 86 MPGe combined. For buyers considering these high-end performance EVs, the slightly lower MPGe of the Audi might be an acceptable trade-off for its distinctive styling, luxurious interior, and the Audi brand cachet.

Tips to maximize efficiency

Preconditioning the cabin is a simple way to conserve battery energy. Whether heating or cooling, doing so while the car is plugged in allows the system to draw power from the grid instead of the battery, preserving range for driving. Many owners overlook this simple step.

Gentle acceleration and smooth braking are key. The RS e-tron GT Performance is capable of neck-snapping acceleration, but frequent hard launches will quickly drain the battery. Instead, focus on using the instant torque responsibly, enjoying the smooth power delivery without constantly pushing the car to its limits.

Take advantage of regenerative braking. Experiment with the different levels of regeneration to find a setting that suits your driving style. Maximizing regen in city driving can significantly increase range, recouping energy that would otherwise be lost during braking.

Monitor tire pressure regularly. Underinflated tires increase rolling resistance, which reduces efficiency. Keeping your tires properly inflated will not only improve fuel economy but also extend tire life and improve handling.

Plan your routes carefully, incorporating charging stops as needed. While the charging infrastructure is constantly improving, it’s still essential to plan longer trips to ensure access to fast chargers. This proactive approach reduces range anxiety and allows you to enjoy the drive without worrying about running out of power. View all Audi fuel economy data.
