The 2025 Audi SQ5 Sportback gets 22 MPG combined. It’s a figure that represents a compromise its drivers are willing to make. No one buys an SQ5 Sportback for its fuel efficiency; they buy it for its potent 3.0-liter turbocharged V6, its sleek coupe-like roofline, standard Quattro all-wheel drive, and the Audi brand. The SQ5 Sportback buyer wants performance and style, and they consciously accept the fuel economy that comes with it.

City and highway performance

The EPA estimates the 2025 Audi SQ5 Sportback at 19 MPG in the city and 26 MPG on the highway. The city figure reflects stop-and-go traffic, where the engine is constantly accelerating, putting a strain on fuel consumption. The highway number, on the other hand, demonstrates the engine’s ability to cruise efficiently at a steady speed, using the 7-speed automatic transmission (AM-S7) to its advantage. While 26 MPG is reasonable, aggressive driving or sustained high speeds will lead to a decrease in fuel economy. Most drivers will see something between these two estimates on a typical commute.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2025 Audi SQ5 Sportback is estimated at $2,650. This figure is calculated based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price. This is an estimate. Individual driving habits, local fuel prices, and even the specific grade of gasoline used can all influence the amount spent on fuel over a year.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often varies. SQ5 Sportback owners who prioritize spirited driving and frequently engage the sport modes will likely see figures closer to the city estimate, or even lower. Drivers who adopt a more conservative driving style, minimize hard acceleration, and spend more time on the highway may achieve mileage closer to, or even slightly above, the EPA’s highway estimate. The SQ5 Sportback requires premium fuel, which contributes to the overall cost.

How it compares

Compared to its competitors, the 2025 Audi SQ5 Sportback’s fuel economy is within the expected range for a performance-oriented SUV. The BMW X4 M40i, a direct rival, achieves a similar 21 MPG combined. The Mercedes-AMG GLC 43 Coupe, another competitor with a turbocharged V6, posts a combined 19 MPG, making the SQ5 Sportback slightly more palatable at the pump. Even within Audi’s own lineup, the differences are significant. You can review all Audi fuel economy data to see how models like the Q5 45 TFSI offer much better fuel efficiency (26 MPG combined), but at the expense of performance. If you’re primarily concerned with fuel efficiency, you may want to review SQ5 MPG across all years to see if past models offered better economy.

Tips to maximize efficiency

The Audi SQ5 Sportback benefits from a proactive approach to fuel efficiency. Avoid aggressive acceleration and braking. The turbocharged engine is responsive, but unnecessary hard starts and stops directly impact fuel consumption. Smooth, gradual acceleration allows the engine to operate more efficiently, and coasting when possible helps conserve fuel.

Ensure proper tire inflation. Correctly inflated tires reduce rolling resistance, which can noticeably improve fuel economy. Check your tire pressure regularly and maintain it at the levels specified on the doorjamb sticker. Even a slight drop in pressure can lead to a decrease in MPG.

Minimize idling time. Letting the engine idle for extended periods wastes fuel. If you anticipate a delay, such as waiting in a parking lot, it’s best to turn off the engine. Modern engines warm up quickly while driving, so there’s no need to idle unnecessarily.

Take advantage of the Audi Drive Select modes. Select the “Efficiency” mode when fuel conservation is a priority. This mode optimizes the engine and transmission settings for maximum efficiency, resulting in improved MPG. The trade-off will be in overall responsiveness.

Regular maintenance is critical. Ensure your SQ5 Sportback receives scheduled maintenance, including oil changes and air filter replacements. A well-maintained engine operates more efficiently, which translates to better fuel economy. Neglecting maintenance can lead to decreased performance and reduced MPG.
