The EPA rates the 2023 Audi Q8 3.0L 6-cyl at 20 MPG combined. For a stylish SUV with aggressive styling, strong performance, and a luxurious interior, many Q8 buyers find it’s a worthwhile trade-off. This vehicle is bought for its presence, performance, and the prestige of the Audi brand, not primarily for saving gas.

City and highway performance

The EPA further breaks down the Q8’s fuel economy, with ratings of 18 MPG in the city and 23 MPG on the highway. The difference in ratings reflects that urban driving with frequent stops requires more acceleration, increasing fuel consumption. On the open road, the Q8’s engine management and eight-speed automatic transmission allow it to cruise with reasonable efficiency. Aggressive driving will significantly impact these numbers, regardless of location.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Audi Q8 3.0L 6-cyl is $2,900. This is based on driving 15,000 miles per year and using national average fuel prices. Individual fuel costs will vary, depending on driving habits, location, and gas prices. Consider this a benchmark but remember that the premium fuel required by the Q8 will likely cost more than the national average used in the EPA calculation.

Real-world expectations

While the EPA estimates are a standardized measure, real-world fuel economy will always vary. Q8 owners who often test drive the vehicle’s performance, use the sport driving modes, or live in hilly areas will likely see lower fuel economy than the EPA estimates. Drivers who accelerate smoothly, use the adaptive cruise control on the highway, and maintain their vehicle may achieve numbers closer to, or even slightly better than, the stated MPG.

How it compares

The Q8’s fuel economy is in line with its competitors. The BMW X6 xDrive40i, equipped with a similar inline-six engine, achieves an EPA-estimated 23 MPG combined. The Mercedes-Benz GLE 450 4MATIC, another rival, also gets around 22 MPG combined, depending on the configuration. Buyers considering the Porsche Cayenne Coupe, which provides a luxurious experience and sporting character, will find the base model delivers roughly the same fuel economy as the Q8. Those who prioritize lower fuel costs might consider the Lexus RX 350h, which delivers close to 36 MPG combined, although its driving experience is very different. For drivers focused on maximum space, all Audi fuel economy data is available for comparison. It is also a good idea to review Q8 MPG across all years to consider different year models that might save you money at the pump.

Tips to maximize efficiency

The Q8’s responsiveness can be addictive, so avoid constantly aggressive acceleration. Accelerate gradually and maintain a steady speed to improve fuel economy.

Take advantage of the Q8’s drive select modes, and select the “Efficiency” mode when possible. This mode optimizes engine and transmission settings to maximize fuel economy.

Ensure your Q8’s tires are properly inflated because underinflated tires increase rolling resistance, reducing fuel economy. Check tire pressures regularly, and inflate them to the recommended levels found on the doorjamb sticker.

Keep up with scheduled maintenance. Consistent oil changes, air filter replacements, and spark plug maintenance keep the engine running efficiently.

Minimize idling. Modern engines do not need long warm-up periods. Shut off the engine if you expect to idle for more than a minute.
