23 MPG combined may not sound great in 2024, but for the Audi Q3 S line quattro with its 2.0L 4-cylinder engine, it’s a reasonable balance between performance, practicality, and luxury. The Q3 S line quattro isn’t a hybrid and isn’t for those focused on maximizing MPG either; it’s designed for young professionals and small families who prioritize style, technology, and all-weather capability in a compact car that is easy to park. Fuel economy, while important, isn’t typically the deciding factor for this group.

City and highway performance

The EPA estimates for the 2024 Audi Q3 S line quattro break down to 20 MPG in the city and 28 MPG on the highway. That 20 MPG city figure reflects stop-and-go traffic and shorter trips, where the engine spends more time at lower speeds. The turbocharged 2.0L engine and eight-speed automatic transmission (S8) deliver responsive acceleration, useful for navigating urban environments but decreasing fuel efficiency. On the open road, the 28 MPG highway figure shows what the Q3 S line quattro can achieve when cruising at consistent speeds. This makes it suitable for longer commutes and road trips, where the aerodynamic profile and gearing can contribute to better fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Audi Q3 S line quattro at $1,900. This is based on driving 15,000 miles per year and using national average fuel prices, but your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and where you live, as fuel prices differ across states. If you primarily drive in the city or have a heavy foot, expect your annual fuel costs to be higher than the EPA estimate. If you do mostly highway driving and practice fuel-efficient driving techniques, you might spend less. This $1,900 is a useful benchmark, but consider it an estimate.

Real-world expectations

Real-world fuel economy can vary from the EPA’s ratings. Q3 drivers report a range of MPG figures, often falling slightly below the official numbers. Aggressive driving, frequent short trips, and cold weather can all hurt fuel efficiency. Some people prioritize smooth acceleration, maintain steady speeds on the highway, and keep their tires properly inflated and are more likely to achieve figures closer to, or even slightly above, the EPA estimates. Check Q3 MPG across all years for trends and comparisons by other owners.

How it compares

The Audi Q3 S line quattro competes in a crowded segment of small luxury SUVs. The BMW X1 xDrive28i achieves a combined 28 MPG, making it more efficient, and the Mercedes-Benz GLA 250 4MATIC is rated at 26 MPG combined. This suggests competitors offer better fuel economy. The Q3 buyer is likely prioritizing factors like Audi’s styling, interior design, or quattro all-wheel-drive system. Even the larger Audi Q5 with its base 40 TFSI powertrain manages 25 MPG combined. Compact size doesn’t always guarantee superior fuel efficiency. For access to all Audi fuel economy data, visit FuelEconomyHub.com.

Tips to maximize efficiency

Drive smoothly. The Q3’s turbocharged engine delivers plenty of torque, so avoid aggressive acceleration and hard braking. Anticipate traffic flow and maintain a steady speed to minimize fuel consumption from bursts of acceleration.

Monitor tire pressure. Underinflated tires increase rolling resistance, which directly reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended levels listed on the driver’s side doorjamb. It can make a difference.

Minimize idling. If you anticipate being stopped for more than a minute, turn off the engine. Modern engines restart quickly, making this a simple way to save fuel, especially in urban environments. Excessive idling wastes fuel and contributes to unnecessary emissions.

Avoid carrying excess weight. Remove unnecessary items from the vehicle, as extra weight increases the engine’s workload and reduces fuel efficiency. Every extra pound counts, so keep the cargo area clear.

Consider using the Audi Drive Select system. Experiment with the different driving modes to find the balance between performance and fuel economy for your driving style and conditions. The “Efficiency” mode optimizes vehicle settings, such as throttle response and transmission shift points, to maximize fuel efficiency.
