The 2023 Audi S5 Sportback gets an EPA-estimated 24 MPG combined. This isn’t the best, or class-leading, but for a stylish, high-performance hatchback with luxury features and standard Quattro all-wheel drive, it’s a trade-off most buyers accept. The S5 Sportback appeals to those who prioritize driving engagement, sleek design, and everyday practicality in a premium car, not ultimate fuel efficiency.

City and highway performance

The EPA estimates the 2023 Audi S5 Sportback achieves 21 MPG in the city and 30 MPG on the highway. The city figure reflects typical stop-and-go traffic, where the S5’s 349-horsepower turbocharged V6 engine is less efficient. The highway number is respectable, showing how the engine cruises efficiently at consistent speeds, aided by the smooth eight-speed automatic transmission that keeps engine speed low. Many owners can realistically achieve the highway figure on long trips. The city fuel economy is more variable, heavily influenced by driving habits and traffic.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Audi S5 Sportback at $2,400. This is based on driving 15,000 miles per year, with 45% in the city and 55% on the highway, using national average fuel prices for premium gasoline, which the S5 requires. Individual fuel costs will change based on driving habits, location, and current fuel prices. Expect the $2,400 figure to increase with aggressive city driving. Spending more time on the open road could lower your annual fuel bill. See all Audi fuel economy data to compare Audi models.

Real-world expectations

EPA estimates provide a benchmark, but real-world fuel economy varies. Some owners might get close to the EPA figures with careful driving and highway cruising. Others who often tap into the S5’s performance in cities will likely see lower numbers. Weather, tire pressure, and using accessories such as air conditioning also affect gas mileage. Check user reviews and forums for the S5 to get a better idea of what drivers experience before reviewing S5 MPG across all years.

How it compares

The S5 Sportback faces competition, and fuel economy matters to buyers. The BMW 440i Gran Coupe, a direct competitor, gets nearly the same 25 MPG combined. The Mercedes-AMG C43 Coupe, with more power, sees similar mileage, in the low 20s. The Acura TLX Type S, with its turbocharged V6, offers similar performance but often lags behind the S5 in real-world fuel economy to around 22 MPG combined. All require premium fuel, adding to the cost. The S5 buyer weighs performance, style, and practicality, knowing a slight fuel economy trade-off is the price for the driving experience and design they want.

Tips to maximize efficiency

Use the Audi Drive Select system. “Efficiency” mode changes the throttle response and shift points to conserve fuel. This will sacrifice some acceleration, but it improves MPG, especially on commutes.

Check tire pressure regularly. Underinflated tires increase rolling resistance, making the engine work harder and burn more fuel. Find the recommended tire pressure on the sticker inside the driver’s side door and maintain it. This easily improves fuel economy and extends tire life.

Avoid quick acceleration and hard braking. The S5’s strong engine is tempting, but smoother driving significantly boosts fuel economy. Anticipate traffic and maintain consistent speed to lower fuel waste. Use cruise control when you can.

Remove extra weight from the car. Excess weight strains the engine and lowers fuel economy. Remove unneeded items from the trunk and passenger area to reduce the load. Every pound matters, especially in the city.

Think about the route you pick. If you can, pick routes with fewer lights and less traffic. A longer route with fewer stops can be more fuel-efficient than a shorter route with gridlock. Use navigation apps to find the best route for less gas.
