88 MPG combined is transformative for a vehicle with the performance of the 2025 Audi S e-tron GT, especially with the optional 21-inch wheels. This is a high-performance electric grand tourer with attractive styling, for drivers who want sports car thrills without impracticality or gas. The S e-tron GT’s energy consumption lets buyers focus on electrifying performance, technology, and style without worrying about range or charging costs. If you want ultimate efficiency, look elsewhere, but this Audi balances performance and economy for a specific appeal.

City and highway performance

The S e-tron GT’s EPA ratings show better performance in the city, achieving 89 MPG compared to 85 MPG on the highway. This is due to the effective regenerative braking system. City driving means frequent deceleration, letting the S e-tron GT recapture energy and replenish the battery, maximizing efficiency. Highway driving, with its sustained speeds and fewer chances for regeneration, results in a slightly lower number. This driving profile is ideal for commuting or running errands in urban environments.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Audi S e-tron GT at $850. This is based on driving 15,000 miles per year and assumes a national average electricity cost of roughly $0.16 per kilowatt-hour. Your actual charging costs will vary depending on your location, electricity provider, time-of-use rates, and driving habits. However, even with fluctuation, the S e-tron GT’s energy efficiency promises savings compared to gasoline-powered sports sedans that can easily cost drivers several thousands of dollars per year.

Real-world expectations

While the EPA numbers are a benchmark, real-world mileage will vary depending on driving style, road conditions, and climate. Aggressive acceleration, frequent use of air conditioning or heating, and sustained high-speed cruising will all reduce efficiency. Cold weather can impact battery performance and range. Most Audi S e-tron GT owners will find that the EPA estimates are generally achievable with mindful driving. Also many owners have home chargers, letting them use the lowest electricity rates overnight and “fill up” while the vehicle sits unused. This reduces the overall cost of ownership.

How it compares

Comparisons show the S e-tron GT’s efficiency among high-performance EVs. For example, the Porsche Taycan 4S, a close relative with similar performance, achieves roughly 79 MPG combined, while the higher-performance Taycan Turbo trims often fall even lower. The Tesla Model S Long Range touts an EPA-estimated 120 MPG combined, which is considerably better, but caters to a different buyer more focused on efficiency than luxury. Even hybrid competitors like the BMW 530e, achieving around 64 MPG combined, fall short. This places the S e-tron GT as offering a blend of driver engagement and electric efficiency.

Tips to maximize efficiency

Take advantage of the Audi’s regenerative braking settings. Experiment with the different levels of regeneration to find the setting that best suits your driving style and maximizes energy recapture, especially during city driving. Often, coasting and allowing the car to gently slow through regeneration can reclaim power.

Precondition the cabin while the vehicle is plugged in. Warming or cooling the interior while the car is connected to the charger reduces the energy demand on the battery when you start driving, preserving driving range.

Monitor tire pressure regularly. Maintaining the recommended tire pressure reduces rolling resistance, improving efficiency. Even a slight drop in pressure can have a noticeable impact on driving range, especially with the larger 21-inch wheels.

Limit aggressive acceleration. While the S e-tron GT offers acceleration, frequent bursts of full power drain the battery quickly. Smooth, gradual acceleration will improve efficiency and extend driving range. For those prioritizng long trips it is recommended to check all Audi fuel economy data.

Plan routes strategically. Use the navigation system to identify charging stations along your route and optimize driving to avoid detours. Familiarize yourself with S MPG across all years which, along with a little pre-planning, can help you avoid running out of power and get to your destination on-time.
