The 2023 Audi SQ8 4.0L 8-cyl gets 17 MPG combined. To be clear, fuel efficiency isn’t the main reason someone buys an SQ8. This is a high-performance SUV that combines aggressive styling, a luxurious interior, and thrilling acceleration into a strong (and thirsty) package. This is a statement vehicle, and its fuel consumption reflects that. The SQ8 buyer wants presence, performance, and prestige. They are less concerned with squeezing every last mile out of a gallon of premium fuel and more interested in the immediate thrust of its twin-turbocharged V8.

City and highway performance

The EPA estimates that the 2023 Audi SQ8 achieves 14 MPG in the city and 20 MPG on the highway. These figures realistically reflect the SQ8’s driving characteristics. In urban environments, the constant stop-and-go traffic and the engine’s eagerness to accelerate off the line contribute to lower fuel economy. On the open road, the SQ8’s eight-speed automatic transmission and cylinder-on-demand technology (which can shut down cylinders under light load) help to improve efficiency, although 20 MPG is still modest compared to more economy-focused SUVs.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Audi SQ8 at $3,400. This calculation is based on driving 15,000 miles per year and using current national average fuel prices. Remember that the SQ8 requires premium fuel, which is typically more expensive than regular gasoline, further contributing to its higher running costs. This $3,400 figure assumes you drive around 41 miles per day. If your daily commute is longer, or if you enjoy frequent spirited drives, expect to surpass this amount.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy can vary significantly depending on driving habits, traffic conditions, and even the weather. Aggressive acceleration, frequent hard braking, and extended idling will all negatively impact fuel consumption. In real use, expect that 17 MPG combined rating to be closer to reality during careful driving. If you regularly exploit the engine’s potential, expect a number south of 17.

You can also explore SQ8 MPG across all years as pre-owned models might have different economy ratings.

How it compares

The SQ8 competes in a segment dominated by high-performance luxury SUVs, none of which are particularly renowned for their fuel efficiency. The BMW X5 M, for example, delivers similar performance but returns an EPA-estimated 15 MPG combined. The Mercedes-AMG GLE 63 S also achieves around 15 MPG combined. Even the Porsche Cayenne Turbo, known for its performance and efficiency, manages only around 17 MPG combined, mirroring the SQ8’s figure. Buyers considering these vehicles typically prioritize performance and luxury over lower fuel costs. If you’re looking for better mileage, consider the standard Q8, which as a V6 engine and delivers significantly better fuel economy, but at the expense of performance. You can explore all Audi fuel economy data to compare models.

Tips to maximize efficiency

Although the SQ8 is not inherently fuel-efficient, there are a few steps owners can take to optimize their MPG. Avoid aggressive acceleration and hard braking. Smooth, gradual inputs will help the engine operate more efficiently. Anticipate traffic flow and maintain a steady speed whenever possible.

Ensure your tires are properly inflated. Under-inflated tires increase rolling resistance, which can negatively affect fuel economy. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications, which can be found on the driver’s side doorjamb.

Minimize idling. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling consumes fuel without moving the vehicle. This can be especially beneficial in urban environments with frequent stoplights.

Use the Audi Drive Select system to your advantage. The SQ8 offers various driving modes that can optimize fuel efficiency. Selecting the “Efficiency” or “Comfort” mode will adjust the engine and transmission settings to prioritize fuel economy over performance.

When road conditions allow, engage cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy compared to manually controlling the throttle. Just remember to disengage it as needed in traffic or changing road conditions.
