20 MPG combined is what you get with the 2021 Audi SQ5 Sportback, a stylish and strong crossover that prioritizes performance and looks over saving fuel. For some, this number will disqualify the Audi immediately. But for those drawn to its turbocharged V6 and coupe-like silhouette, it’s an acceptable tradeoff. This isn’t a vehicle for penny-pinchers; it’s for those who value driving pleasure and design flair and are willing to pay a bit more at the pump.

City and highway performance

The EPA estimates of 18 MPG in the city and 24 MPG on the highway tell a more nuanced story. The city figure reflects the stop-and-go realities of urban driving, where the SQ5 Sportback’s 3.0-liter turbocharged V6 can feel a bit thirsty as it repeatedly spools up and slows down. However, the 24 MPG highway estimate indicates that the engine is relatively efficient when cruising at consistent speeds. This suggests that drivers who log significant highway miles will see fuel economy closer to that upper limit. The eight-speed automatic transmission (S8) plays a key role here, optimizing engine speed for efficiency at higher speeds. All-wheel drive (Quattro) is standard and contributes to the overall weight, adding to the fuel consumption.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Audi SQ5 Sportback at $2,900. This figure is based on driving 15,000 miles per year, with a roughly even split between city and highway driving, and using national average fuel prices. Individual fuel costs will vary based on driving habits, local fuel prices, and the specific grade of gasoline used; premium fuel is recommended. While $2,900 is a significant amount, it needs to be put in context. Buyers considering a performance-oriented crossover likely anticipate higher-than-average fuel costs, and for many, the fun of driving an SQ5 Sportback outweighs the concern over a few extra dollars at the gas station.

Real-world expectations

Although the EPA provides a standardized benchmark, many SQ5 Sportback owners report real-world fuel economy that varies from the official estimates. Aggressive driving, frequent acceleration, and prolonged idling can all significantly reduce fuel efficiency. On the other hand, those who focus on smooth acceleration, anticipate traffic flow, and use the vehicle’s driving modes to their advantage may see figures closer to, or even slightly above, the EPA estimates. The “Dynamic” driving mode, which sharpens throttle response and holds gears longer, will undoubtedly impact fuel consumption, while the “Efficiency” mode promotes earlier upshifts and coasting to conserve fuel. Checking SQ5 MPG across all years can provide a broader understanding of typical owner experiences.

How it compares

In the performance crossover market, the 2021 Audi SQ5 Sportback’s fuel economy is neither exceptional nor terrible. The BMW X4 M40i, a direct competitor, achieves a similar 23 MPG combined, showing that performance and efficiency are a tradeoff in this category. The Mercedes-AMG GLC 43 Coupe, another rival, lands in the same ballpark. However, choosing a less performance oriented trim matters: opt for the base GLC 300 and you can reach 25 MPG combined because of its milder engine tune. The Porsche Macan S offers a comparable driving experience, but its fuel economy is also very similar to the SQ5 Sportback. These comparisons highlight that buyers in this segment typically prioritize power and handling over maximizing MPG, so the Audi’s fuel economy is one among many factors they weigh while shopping.

Tips to maximize efficiency

Use the Audi Drive Select system. The “Efficiency” mode optimizes engine and transmission settings for saving fuel, potentially yielding noticeable improvements on longer drives. Experiment with different modes to find the best balance between performance and efficiency for your driving style.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Maintaining the recommended tire pressure, which can be found on the doorjamb sticker, is a simple yet effective way to improve gas mileage.

Anticipate traffic flow and practice smooth acceleration. Avoid jerky starts and hard braking, as these actions waste fuel. By anticipating traffic and maintaining a consistent speed, you can reduce the need for sudden acceleration and deceleration.

Minimize idling. Idling for extended periods consumes fuel without covering any distance. If you’re stopped for more than a minute or two, consider turning off the engine to save fuel, especially in urban environments.

Consider removing unnecessary weight. Carrying excessive cargo adds to the vehicle’s overall weight, which negatively impacts fuel economy. Removing items you don’t regularly use can help improve gas mileage, especially on city streets.
