19 MPG combined is the reality for 2024 Audi Q8 quattro 3.0L owners. This isn’t Prius territory. The Q8 is a statement, a luxury SUV that prioritizes expressive design, potent performance, and cutting-edge technology. Fuel efficiency, while not irrelevant, is less important than these core attributes. The Q8 doesn’t apologize for its thirst; its buyers understand that indulging in its unique blend of style and substance comes at a price, and that price includes more frequent trips to the gas station.

City and highway performance

The Q8’s EPA ratings break down to 17 MPG in the city and 23 MPG on the highway. The lower city figure reflects the demands placed on the 3.0-liter turbocharged V6 engine during stop-and-go driving, with frequent acceleration and idling. The highway figure is more respectable, and attainable in practice, thanks to the smooth-shifting eight-speed automatic transmission (S8) and Audi’s quattro all-wheel-drive system. The quattro system enhances grip and stability, but adds weight and complexity, contributing to the overall fuel consumption. Long highway trips at consistent speeds are where the Q8’s efficiency shines, relatively speaking.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Audi Q8 quattro at exactly $3,050. This figure is based on driving 15,000 miles per year, with a specific percentage assumed to be city versus highway miles, and using the national average fuel price for premium unleaded gasoline. This is an estimate. Your actual fuel costs will vary depending on your driving habits, local fuel prices, and the specific blend of fuel you use. However, $3,050 provides a benchmark, and a stark reminder that owning a luxury SUV with a performance-oriented engine isn’t cheap, with all Audi fuel economy data readily available to compare.

Real-world expectations

Real-world MPG numbers will vary. Aggressive driving, frequent short trips, and extended idling will all reduce fuel economy below the EPA estimates. Gentle acceleration, anticipatory braking, and prioritizing highway driving can help you approach or even slightly exceed the official numbers. The Q8’s driver-selectable modes, including an “Efficiency” setting, can subtly influence fuel consumption. Accept that the Q8 prioritizes performance and driving enjoyment over fuel savings.

How it compares

The Q8’s fuel economy puts it squarely in line with other performance-oriented luxury SUVs, but it’s worthwhile to understand how it measures up against the competition. The BMW X6 xDrive40i, with its turbocharged inline-six, achieves a similar 23 MPG combined. The Mercedes-Benz GLE 450 4MATIC also hovers around 21 MPG combined. A Porsche Cayenne, known for its driving dynamics, lands in a slightly lower range, depending on the engine configuration chosen. Electrified or hybrid models like the Lexus RX 450h offer significantly better fuel economy, but at the expense of driving performance and distinctive design. Q8 buyers aren’t typically cross-shopping with a Lexus; they prioritize a specific European aesthetic and driving experience.

Tips to maximize efficiency

Use the Audi Drive Select. The “Efficiency” mode optimizes the engine and transmission settings for the best possible fuel economy. The differences may not be drastic, but it’s a small effort that can add up over time. Experiment with it and be conscious of how your driving style changes.

Monitor tire pressure regularly. Underinflated tires create more rolling resistance, which reduces fuel economy. The Q8’s tire pressure monitoring system (TPMS) provides a constant readout, but visually inspect your tires frequently to catch any issues early. Always inflate to the recommended pressure listed on the door jamb sticker.

Avoid unnecessary idling, which consumes fuel without covering any distance. If you anticipate being stopped for more than a minute, switch off the engine. The Q8’s start-stop system automatically shuts off the engine at traffic lights, further reducing idle fuel consumption in the city.

Minimize aggressive acceleration and braking. Gentle, gradual inputs are safer and more fuel-efficient. Anticipate traffic flow and maintain a steady speed whenever possible. The Q8’s powerful engine is responsive, so you don’t need to constantly bury the accelerator.

Reduce excess weight in the vehicle. The heavier the vehicle, the more fuel it consumes. Remove unnecessary items from the trunk and cargo area to lighten the load. This is particularly relevant if you tend to accumulate sporting equipment or other bulky items.
