85 MPG combined is a remarkable figure for the 2024 Audi RS e-tron GT, especially when you consider what this car actually is: a blisteringly fast, all-wheel-drive, four-door grand tourer with a curb weight around 5,100 pounds. It’s not a Prius, and it’s not trying to be. The RS e-tron GT caters to buyers who demand supercar-level performance in a luxurious and technologically advanced package. Efficiency, while important, is secondary to exhilaration. These drivers want to minimize their environmental impact without sacrificing the visceral thrill of driving a truly exceptional machine, which makes this impressive MPG figure all the more appealing.

City and highway performance

Predictably, the EPA rates the RS e-tron GT at 85 MPG for both city and highway driving. This surprising parity comes from the vehicle’s electric powertrain and regenerative braking system, which recoup energy during deceleration, making city driving almost as efficient as cruising on the open road. Instant torque delivery from the electric motors ensures rapid acceleration in urban environments, while aerodynamic efficiency and meticulously managed power consumption contribute to consistent economy at higher speeds. This parity between city and highway figures is a common trait amongst modern EVs for those who frequent all Audi fuel economy data pages.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Audi RS e-tron GT at precisely $900. This calculation is based on driving 15,000 miles per year, with fuel prices reflecting a national average. Individual results will vary depending on electricity rates in your region and your specific driving habits, but this benchmark provides a valuable point of comparison when considering alternative vehicles. $900 a year to drive cross-country is quite a bargain, especially considering the vehicle’s performance characteristics.

Real-world expectations

While the EPA numbers provide a standardized benchmark, real-world efficiency can fluctuate based on several factors. Aggressive acceleration, frequent use of the “Boost” mode, and extreme weather conditions can all impact range and overall MPG. On the other hand, careful driving techniques, strategic use of regenerative braking, and pre-conditioning the battery while plugged in can help to maximize efficiency and potentially exceed the EPA estimates, which is the case on RS MPG across all years. The biggest variable is how heavy on the throttle the driver is.

How it compares

The electric vehicle market is constantly evolving, and several competitors vie for attention in the high-performance EV segment. The Porsche Taycan Turbo, another closely related vehicle, achieves a combined EPA rating of 79 MPG. The Tesla Model S Plaid, despite its blistering acceleration, manages a combined 116 MPG. The less powerful BMW i4 M50 achieves 96 MPGe Combined. Ultimately, the RS e-tron GT buyer isn’t solely focused on maximizing efficiency. They’re balancing performance, luxury, and lower fuel costs, and the Audi strikes a good balance, even if its MPG figure isn’t the absolute highest.

Tips to maximize efficiency

Smooth and consistent acceleration is crucial for maximizing the RS e-tron GT’s efficiency. Avoid abrupt starts and stops. Let the regenerative braking system do its job whenever possible to recapture energy and extend your driving range. Anticipate traffic flow and adjust your speed accordingly.

Pre-conditioning the battery before driving can significantly improve efficiency, particularly in cold weather. Use the Audi connect app to schedule pre-conditioning while the car is plugged in. This warms the battery to its optimal operating temperature using grid power, minimizing energy draw from the battery itself during your drive.

Pay attention to tire pressure. Properly inflated tires reduce rolling resistance, improving efficiency and extending range. Check your tire pressure regularly and maintain it at the recommended levels. You can find the recommended pressure on a sticker inside the driver’s side door jamb.

Minimize aerodynamic drag. Remove any unnecessary items from the roof rack or cargo carrier, as these can significantly increase drag and reduce efficiency. Even small changes like ensuring your windows are closed at highway speeds can make a difference.
