81 MPG combined makes the 2023 Audi RS e-tron GT a performance car with lower fuel costs. This isn’t about hypermiling, it’s about fast acceleration, great handling, and luxurious features, all with gas mileage that was unthinkable in a car this capable just a few years ago. The RS e-tron GT attracts a specific buyer: someone who wants the thrill of a sports car but is also aware of their impact on the environment and the rising cost of gasoline. They don’t want to compromise, and the RS e-tron GT delivers the best of both worlds.

City and highway performance

The EPA numbers for the 2023 Audi RS e-tron GT show a close range between city and highway driving. The car gets 79 MPG in the city and 82 MPG on the highway. This similar efficiency across different driving conditions shows Audi’s electric drivetrain and energy management system. It means that the car handles stop-and-go traffic and sustained high-speed cruising well. Regeneration technologies help, allowing the car to recapture energy during braking and deceleration in urban environments. On the highway, aerodynamics help achieve consistent consumption at higher speeds. For drivers who split their time between city streets and open roads, the RS e-tron GT presents a good option for electric performance.

Annual fuel cost

Based on EPA estimates, the annual fuel cost for the 2023 Audi RS e-tron GT is $950. This is based on driving 15,000 miles per year and using the then-current national average electricity prices. This figure is very different from the fuel costs of traditional high-performance vehicles. The savings are big, allowing owners to spend money typically spent on gas on track days, driver training, or extended road trips. This lower running cost is a big factor in the decision for environmentally conscious performance enthusiasts.

Real-world expectations

While the EPA provides a standard, real-world efficiency changes based on driving style, ambient temperature, and terrain. Hard acceleration and frequent use of “boost” mode will drain the battery faster. However, a more conservative driving style, focusing on smooth acceleration and maximizing regenerative braking, can produce even better numbers. Owners who live in colder climates should expect a reduction in range, as battery performance decreases in low temperatures. Even under less-than-ideal conditions, getting more than 70 MPG equivalent is possible for most owners, which is better than most gas-powered performance cars.

How it compares

The main competitors to the RS e-tron GT are gasoline-powered performance sedans and other high-end electric vehicles. The BMW M5 typically achieves around 17 MPG combined, while the Porsche Panamera Turbo S manages about 20 MPG. These vehicles offer fast performance, however their fuel consumption is much worse than the Audi. Even compared to other EVs, like the Porsche Taycan Turbo S (76 MPG combined), the RS e-tron GT compares favorably. These comparisons are relevant to buyers who are cross-shopping based on performance and lower fuel costs. The savings on fuel are one consideration compared to the driving experience, but potential buyers of the RS E-Tron GT should be aware of the other options.

Tips to maximize efficiency

One of the best ways to improve the efficiency of the RS e-tron GT is to make the most of its regenerative braking system. Watch traffic flow and coast when possible. This lets the car recapture kinetic energy and slow down, instead of relying on the friction brakes. Learn the regeneration modes and select the one that suits your driving style. You will see a difference in the range quickly.

Preconditioning the cabin while the car is plugged in can improve efficiency, especially in cold weather. This warms the battery to its optimal operating temperature before you start driving, which reduces the energy needed to heat the cabin and battery during your journey. This can retain more range during the drive and improve vehicle comfort.

Reduce weight. Remove any unneeded items from the trunk and passenger compartment. Extra weight increases the energy needed to accelerate and maintain speed. The RS e-tron GT is designed to carry passengers and cargo, and reducing unneeded weight can improve fuel economy in the city and on the highway.

Watch tire pressure. Under-inflated tires create more rolling resistance, which reduces efficiency. Properly inflated tires improve fuel economy, enhance handling, and prolong the lifespan of the tires. Check the tire pressure regularly and keep it at the recommended level, which is on the door jamb or in the owner’s manual.

Monitor your driving habits. Hard acceleration and hard braking can reduce efficiency. Smooth driving will produce the best results. Watch the power meter and try to avoid going into the “power” zone. Driving with a lighter foot saves energy and extends the driving range. All Audi fuel economy data is available for comparison, as is RS MPG across all years.
